Polydactyly, the presence of extra fingers and toes, is a fascinating genetic trait that has intrigued scientists and medical professionals for centuries. While most individuals have the typical five fingers and toes, polydactyly occurs when there is an abnormal development of these digits, resulting in the presence of extra ones. This condition can vary in severity, with some individuals having only small, non-functional extra digits, and others having fully formed, functional extra fingers or toes.
The study of polydactyly genetics has provided valuable insights into the inheritance patterns and causes of this condition. It is well established that polydactyly can be inherited, meaning that it is passed down from parents to their children through specific genes. However, the exact genetic mechanisms behind the development of extra fingers and toes are still being actively studied and understood.
Several genetic factors have been implicated in the development of polydactyly. In some cases, the condition is caused by mutations in specific genes that are responsible for the development and patterning of the limbs during embryonic development. These mutations can disrupt the normal signaling pathways and result in the formation of extra digits. Other cases of polydactyly are believed to have a multifactorial inheritance, meaning that both genetic and environmental factors contribute to the development of the condition.
What is Polydactyly?
Polydactyly is a genetic condition characterized by the presence of extra fingers or toes. It is one of the most common limb malformations and can occur in both humans and animals. The word “polydactyly” is derived from the Greek words “poly,” meaning multiple, and “daktylos,” meaning finger or toe.
Types of Polydactyly
There are different types of polydactyly, including preaxial polydactyly, postaxial polydactyly, and central polydactyly.
Preaxial polydactyly refers to the presence of extra digits on the thumb or big toe side of the hand or foot. This is the most common type of polydactyly and can range from just a small skin tag to a fully formed extra finger or toe.
Postaxial polydactyly, on the other hand, is characterized by extra digits on the little finger or toe side of the hand or foot. Central polydactyly involves the presence of extra digits in the middle of the hand or foot.
Causes of Polydactyly
Polydactyly can be inherited from one or both parents, or it can occur as a result of spontaneous genetic mutations. It is often caused by changes in certain genes that are involved in limb development during fetal development.
Researchers have identified several genes that are associated with polydactyly, including the GLI3, HOXD13, and PITX1 genes. Mutations in these genes can disrupt the normal formation of fingers and toes, leading to the development of extra digits.
While most cases of polydactyly are isolated and not associated with other health problems, it can sometimes occur as part of a genetic syndrome or underlying medical condition.
Understanding the genetics behind polydactyly is important for diagnosing and managing the condition. Genetic counseling can help individuals and families understand the inheritance patterns and risks associated with polydactyly.
The Genetics of Polydactyly
Polydactyly is a condition characterized by the presence of extra fingers or toes. It can occur in isolation or as part of a syndrome and can be inherited in several different ways.
There are two main types of polydactyly: preaxial and postaxial. Preaxial polydactyly refers to the presence of extra digits on the thumb side of the hand or the big toe side of the foot. Postaxial polydactyly, on the other hand, refers to the presence of extra digits on the pinky side of the hand or the little toe side of the foot.
The inheritance pattern of polydactyly varies depending on the specific genetic mutations involved. In some cases, polydactyly is inherited in an autosomal dominant manner, which means that a person only needs to inherit one copy of the mutated gene to develop the condition. Other cases of polydactyly are inherited in an autosomal recessive manner, which means that a person needs to inherit two copies of the mutated gene (one from each parent) to develop the condition.
There are also cases of polydactyly that are caused by random mutations that occur during embryonic development. These mutations are not inherited and are considered to be sporadic cases of polydactyly.
In addition to genetic factors, environmental factors can also play a role in the development of polydactyly. For example, exposure to certain drugs or chemicals during pregnancy may increase the risk of a baby being born with extra fingers or toes.
If a person has polydactyly, genetic testing may be recommended to determine the specific genetic mutation involved and to assess the risk of passing the condition on to future generations. Genetic counseling can also be helpful in providing information and support for individuals and families affected by polydactyly.

Types of Polydactyly
Polydactyly, the presence of extra fingers or toes, can be classified into several different types based on its characteristics and inheritance patterns. In general, polydactyly can be categorized as either preaxial or postaxial polydactyly.
Preaxial polydactyly refers to the presence of extra digits on the thumb or big toe side of a limb. This type of polydactyly is often inherited in an autosomal dominant manner, meaning that a person only needs to inherit one copy of the affected gene from either parent to express the disorder. Preaxial polydactyly can vary in severity, ranging from a minor duplication of the thumb to a fully formed extra digit.
Postaxial polydactyly, on the other hand, refers to the presence of extra digits on the pinky or little toe side of a limb. This type of polydactyly can also be inherited in an autosomal dominant manner, or it can be sporadic. Sporadic cases of postaxial polydactyly may be caused by mutations in certain genes or by environmental factors.
There are also different subtypes of polydactyly within the preaxial and postaxial categories. These subtypes can be based on the number, size, and structure of the extra digits. For example, preaxial polydactyly can manifest as a small, soft extra digit called a nubbin, or it can present as a fully formed, functional finger or toe. Similarly, postaxial polydactyly can range from a small, non-functional digit to a fully formed extra finger or toe.
Understanding the different types of polydactyly is crucial for genetic counseling, diagnosis, and treatment options. By identifying the specific type and inheritance pattern of polydactyly, healthcare professionals can provide accurate information and guidance to individuals and families affected by this condition.
Postaxial polydactyly is a form of polydactyly where the extra digits are located on the outside of the hand or foot, away from the thumb or big toe. It is also known as ulnar polydactyly, as the extra digits are found along the ulnar (pinky finger) side.
This condition can vary in severity, from a small, non-functional extra finger or toe to a fully formed digit that may have bones, joints, and even nails. The extra digits may be fully developed or incompletely formed, and they can vary in size and shape.
Postaxial polydactyly can occur in isolation, where it is the only abnormality present, or it may be part of a larger syndrome or genetic disorder. In some cases, it may be inherited as an autosomal dominant trait, meaning that it is passed down from one affected parent to their children.
The underlying cause of postaxial polydactyly can vary. It may be caused by genetic mutations that affect the development of the limb during embryogenesis. Environmental factors and maternal age may also play a role in the development of this condition.
Testing and diagnosis may involve a physical examination, imaging studies such as X-rays or ultrasounds, and genetic testing to identify any underlying genetic mutations. Treatment options depend on the severity of the polydactyly and may include surgical removal of the extra digits or reconstructive procedures to improve their functionality and appearance.
Overall, postaxial polydactyly is a complex condition that can have a significant impact on an individual’s hand or foot function and appearance. Ongoing research and advancements in genetics are improving our understanding of the underlying causes and providing new insights into treatment options for individuals with this condition.
Preaxial polydactyly is a genetic condition characterized by the presence of extra fingers or toes on the thumb or big toe side of the hand or foot. It can occur as an isolated condition or as part of a syndrome. This condition is caused by genetic mutations that affect the development of the limbs.
Preaxial polydactyly can be either inherited or occur sporadically. Inherited preaxial polydactyly follows an autosomal dominant pattern of inheritance, which means that a child has a 50% chance of inheriting the condition if one of their parents carries the gene mutation. Sporadic preaxial polydactyly occurs randomly and is not passed down from parents to children.
Genetic studies have identified several genes that are associated with preaxial polydactyly. These genes play important roles in limb development and the formation of fingers and toes. Mutations in these genes can disrupt the normal development of the limbs, leading to the formation of extra digits.
Preaxial polydactyly can vary in severity, ranging from a small, non-functional extra digit to a fully formed and functional extra finger or toe. The treatment for preaxial polydactyly depends on the specific characteristics of the extra digit and its effect on hand or foot function. In some cases, surgical intervention may be necessary to remove or correct the extra digit.
Understanding the genetics of preaxial polydactyly is important for diagnosing the condition and providing appropriate medical management and genetic counseling. By studying the genes and molecular mechanisms involved in limb development, researchers hope to uncover new insights into the causes and potential treatments for preaxial polydactyly.
Central polydactyly, also known as mesoaxial polydactyly or preaxial polydactyly type II, is a rare form of polydactyly that involves the duplication of the central digits. It is characterized by the presence of extra fingers or toes on the side of the thumb or big toe.
The inheritance pattern of central polydactyly is complex and is believed to be influenced by both genetic and environmental factors. Studies have shown that mutations in certain genes, such as the GLI3 gene, are associated with this condition. The GLI3 gene provides instructions for making a protein that is involved in the development of limbs. Mutations in this gene can disrupt the normal development of the digits, leading to the formation of extra fingers or toes.
In addition to genetic factors, environmental factors such as maternal alcohol consumption and exposure to certain medications during pregnancy have also been linked to an increased risk of central polydactyly. These factors can interfere with the normal development of the limbs in the developing fetus.
Furthermore, there is evidence to suggest that central polydactyly may have a multifactorial inheritance pattern, meaning that both genetic and environmental factors contribute to its development. This makes studying and understanding the causes of this condition challenging.
The treatment for central polydactyly depends on the severity of the condition and its impact on the individual’s daily activities. In some cases, surgical intervention may be necessary to remove the extra digit and restore normal function. The timing of the surgery will depend on the age of the individual and the complexity of the digits.
Genetic counseling may also be recommended for individuals and families affected by central polydactyly. A genetic counselor can provide information about the inheritance pattern of the condition and the likelihood of passing it on to future generations. They can also discuss available treatment options and provide advice and support.
Overall, continued research is needed to further understand the genetics and causes of central polydactyly. This knowledge will help in the development of more effective diagnostic tools and treatment strategies for individuals affected by this condition.
Inheritance Patterns of Polydactyly
Polydactyly is a condition characterized by the presence of extra fingers or toes. It can be inherited in several different patterns, depending on the underlying genetic factors.
One of the most common inheritance patterns of polydactyly is autosomal dominant. This means that if a parent has polydactyly, there is a 50% chance that each of their children will also have the condition. In autosomal dominant polydactyly, only one copy of the mutated gene is needed to cause the extra digits.
In some cases, polydactyly can also be inherited in an autosomal recessive manner. This means that both parents must carry a copy of the mutated gene in order for their child to have polydactyly. If both parents are carriers, there is a 25% chance that their child will have the condition.
In rare cases, polydactyly can be caused by a chromosomal abnormality, such as a duplication or deletion of genetic material. These chromosomal abnormalities can be inherited from a parent or can occur spontaneously.
It is important to note that not all cases of polydactyly are inherited. Some cases can occur as spontaneous mutations, meaning that there is no family history of the condition. These cases are thought to occur due to random genetic changes during development.
Overall, understanding the inheritance patterns of polydactyly is essential in determining the likelihood of passing on the condition to future generations. Genetic counseling can be helpful for individuals and families who are concerned about the risk of polydactyly and want to understand the underlying causes.
Autosomal Dominant Inheritance
In the field of genetics, polydactyly can be inherited in different ways. One of the most common patterns of inheritance is known as autosomal dominant inheritance. This means that the gene responsible for polydactyly is located on one of the autosomal chromosomes, rather than the sex chromosomes.
In autosomal dominant inheritance, a person needs to inherit only one copy of the abnormal gene from one parent in order to develop extra fingers or toes. This means that if one parent has polydactyly, there is a 50% chance that each child they have will also have the condition.
It is important to note that even if an individual has polydactyly, it does not necessarily mean that their parents also have the condition. This is because the trait can skip generations or can be caused by a new mutation in the affected individual.
When studying the genetics of polydactyly, researchers have discovered several genes that are associated with the development of extra fingers and toes. Mutations in these genes can disrupt the normal development of limbs during embryonic development, leading to the formation of additional digits.
Understanding the inheritance patterns and genetic causes of polydactyly is crucial for both research purposes and for individuals and families affected by the condition. It can aid in genetic counseling, family planning decisions, and potentially pave the way for future treatments and interventions.
Autosomal Recessive Inheritance
Autosomal recessive inheritance is one of the patterns of inheritance that can contribute to polydactyly. In this type of inheritance, both parents must carry the non-disease-causing gene variant, known as the recessive allele, in order for their child to be born with polydactyly. If both parents are carriers, there is a 25% chance with each pregnancy that their child will inherit the polydactyly trait.
To better understand autosomal recessive inheritance, it is important to know the basics of genetics. An individual has two copies of each gene, one inherited from each parent. In autosomal recessive inheritance, the gene responsible for polydactyly is on an autosome, which is any chromosome other than a sex chromosome.
If an individual inherits one copy of the recessive allele from one parent and a non-disease-causing allele from the other parent, they will be a carrier of the polydactyly trait but will not have the physical characteristic themselves. Carriers can still pass the trait on to their offspring if their partner is also a carrier. Only when an individual inherits two copies of the recessive allele from both parents will they have polydactyly.
It is important to note that not all cases of polydactyly are caused by autosomal recessive inheritance. There are other genetic and non-genetic factors that can contribute to the development of extra fingers and toes. Additionally, genetic counseling and testing can provide more accurate information about an individual’s specific genetic risks and the likelihood of passing on the trait to their children.
The study of genetics is essential in understanding the inheritance patterns of polydactyly. Genes contain the instructions for the development and functioning of an organism. By studying the genes involved in polydactyly, scientists can gain insights into the underlying mechanisms and potential treatments for this condition. Continued research in genetics is crucial for further advances in the understanding and management of polydactyly.
While most cases of polydactyly are inherited in an autosomal dominant or recessive manner, there is also an X-linked pattern of inheritance. X-linked polydactyly occurs when the gene responsible for the extra fingers or toes is located on the X chromosome.
In X-linked inheritance, the chance of developing polydactyly depends on the sex of the individual and whether they inherit the affected X chromosome. Females have two X chromosomes (XX), while males have one X and one Y chromosome (XY).
X-Linked Recessive Polydactyly
In X-linked recessive polydactyly, females with one affected X chromosome are carriers of the condition but do not typically show any symptoms. However, they have a 50% chance of passing the affected X chromosome to their children, who may then develop polydactyly.
Males, on the other hand, have a higher risk of developing polydactyly if they inherit the affected X chromosome. This is because males have only one X chromosome, so if they receive the affected X chromosome from their mother, they will have the condition.
X-Linked Dominant Polydactyly
In X-linked dominant polydactyly, both males and females can show symptoms of the condition if they inherit the affected X chromosome. However, females are more likely to be affected since they have two X chromosomes and a higher chance of inheriting the affected one.
Males, on the other hand, have a higher risk of having more severe symptoms if they inherit the affected X chromosome, as they do not have a second X chromosome to compensate for the gene mutation.
Causes of Polydactyly
Polydactyly is a genetic condition characterized by the presence of extra fingers or toes. This condition can be caused by various factors, including genetic mutations and environmental influences.
One of the main causes of polydactyly is a genetic mutation. Mutations can occur in different genes that are involved in the development of limbs during embryonic development. These mutations can disrupt the normal signaling pathways and lead to the formation of extra fingers or toes. There are several genes that have been identified to be associated with polydactyly, including the Sonic Hedgehog (SHH) gene and the GLI3 gene.
Environmental factors can also contribute to the development of polydactyly. Certain medications, such as thalidomide, have been known to increase the risk of polydactyly when taken during pregnancy. This is because these medications can interfere with normal limb development in the fetus. Additionally, exposure to certain toxins and chemicals during pregnancy may also increase the risk of polydactyly.
In some cases, the exact cause of polydactyly may be unknown. It is possible that a combination of genetic and environmental factors contribute to the development of this condition. Further research is needed to fully understand the causes and mechanisms behind polydactyly.
Polydactyly is a genetic condition that results in individuals being born with extra fingers or toes. This condition is caused by genetic mutations, which are changes in the DNA sequence that can alter the structure or function of genes.
There are several types of genetic mutations that can lead to polydactyly. One common mutation is a duplication of the SHH gene, which is responsible for the development of limbs. This duplication can result in the formation of an extra digit.
Another type of mutation that can cause polydactyly is a loss-of-function mutation. This type of mutation leads to the inactivation or loss of a gene, which can disrupt the normal development of limbs and result in the formation of extra fingers or toes.
Genetic mutations that cause polydactyly can be inherited from a parent or can occur spontaneously during embryonic development. Inherited mutations are usually passed down in an autosomal dominant pattern, which means that only one copy of the mutated gene is necessary to produce the trait. However, the severity and expression of polydactyly can vary among individuals with the same mutation.
Studying genetic mutations associated with polydactyly is important for understanding the underlying causes of this condition. It can provide insights into the development of limbs and help researchers develop targeted therapies or interventions to prevent or treat polydactyly.
|Types of Genetic Mutations
|Duplication of SHH gene
|Alteration in limb development
|Inactivation or loss of gene
In addition to genetics, there are several environmental factors that can contribute to the occurrence of polydactyly, or the presence of extra fingers and toes.
Exposure to certain substances or conditions during pregnancy can increase the risk of polydactyly. For example, exposure to certain medications, chemicals, or infections during fetal development may disrupt the normal formation of fingers and toes, leading to the development of extra digits.
The health of the mother during pregnancy can also play a role in the development of polydactyly. Certain maternal health conditions, such as diabetes, can increase the risk of abnormalities in fetal development, including polydactyly.
Teratogens are substances that can cause birth defects when a fetus is exposed to them during pregnancy. Some teratogens, such as certain drugs or alcohol, have been associated with an increased risk of polydactyly.
Exposure to certain environmental hazards, such as radiation or chemicals, can also increase the risk of polydactyly. Studies have shown that individuals who live near nuclear power plants or are exposed to high levels of certain chemicals may have a higher incidence of polydactyly.
While genetics and environmental factors can contribute to the development of polydactyly, it is important to note that not all cases can be prevented. However, taking certain precautions during pregnancy can help reduce the risk. This includes avoiding exposure to harmful substances, maintaining good maternal health, and seeking appropriate medical care throughout pregnancy.
Understanding the influence of both genetics and environmental factors is crucial in understanding the causes of polydactyly. While genetic factors play a significant role, environmental factors can also contribute to the occurrence of this condition. Further research is needed to fully understand the complex interactions between genetics and the environment in the development of polydactyly.
Symptoms of Polydactyly
Polydactyly is a genetic condition that results in the development of extra fingers or toes on a person’s hands or feet. The most common form of polydactyly is known as postaxial polydactyly, which is characterized by the presence of an extra finger or toe on the outer side of the hand or foot. In some cases, the extra digit may be fully formed and functional, while in others it may be smaller or not fully developed.
Polydactyly can vary in severity. Some individuals may have only one extra finger or toe, while others may have multiple additional digits. The extra digit may be located next to the little finger or toe, or it can be found anywhere along the outer edge of the hand or foot. The size and appearance of the extra digit can also vary, ranging from a small skin tag to a fully formed finger or toe with bones, joints, and nails.
In addition to the physical symptoms, polydactyly can also be associated with other genetic conditions or syndromes. For example, it is commonly seen in individuals with Down syndrome, Ellis-van Creveld syndrome, or Holt-Oram syndrome. These conditions can have additional symptoms and implications for a person’s overall health and development.
In summary, polydactyly is a genetic condition characterized by the presence of extra fingers or toes. The severity, location, and appearance of the extra digit can vary. It can occur as an isolated condition or be associated with other genetic conditions or syndromes. Understanding the symptoms and genetic factors involved in polydactyly can help in its diagnosis and management.
Diagnosis of Polydactyly
The diagnosis of polydactyly is typically based on a physical examination and medical history. The presence of extra fingers or toes is usually apparent at birth or shortly thereafter. However, in some cases, polydactyly may not be immediately obvious and may only become apparent as the child grows.
During the physical examination, the doctor will assess the number and location of extra digits, as well as their size, shape, and functionality. They may also look for other associated abnormalities or genetic syndromes that may be present in conjunction with polydactyly.
Genetic testing may be recommended in certain cases to help determine the cause of polydactyly. This can involve analyzing the DNA of the affected individual and their parents to identify specific genetic mutations or changes that may be responsible for the condition.
There are several genetic syndromes that can cause polydactyly, such as Greig cephalopolysyndactyly syndrome and Bardet-Biedl syndrome. Genetic testing can help differentiate between these syndromes and provide important information regarding inheritance patterns.
In some cases, imaging studies such as X-rays or ultrasounds may be performed to further evaluate the bones and soft tissues of the hand or foot. These imaging studies can provide more detailed information about the structure and anatomy of the extra digits, as well as any associated abnormalities.
Overall, an accurate diagnosis of polydactyly is important to guide appropriate management and treatment options. It can also provide valuable information regarding the inheritance of the condition, which can help with family planning and genetic counseling.
When diagnosing polydactyly, a physical examination is typically the first step. The healthcare provider will carefully examine the hands and feet of the individual to determine the number of fingers and toes present, as well as their size, shape, and overall structure. They will also look for any other associated abnormalities in the hands and feet.
In addition to the visual examination, the healthcare provider may also perform certain tests to assess the functionality of the extra digits. This can include examining the range of motion and strength of the fingers and toes, as well as checking for any difficulties in grasping or walking.
Furthermore, the healthcare provider may take measurements of the fingers and toes to document their length, width, and any variations in size. This information can help in determining the severity of the polydactyly and its potential impact on the individual’s daily activities and overall quality of life.
Overall, a thorough physical examination is crucial in diagnosing polydactyly and assessing its genetic basis. This examination helps healthcare providers determine the best course of treatment and provide appropriate genetic counseling to affected individuals and their families.
|Assessment of the number, size, shape, and structure of the fingers and toes.

|Measuring the length, width, and variations in size of the fingers and toes.
In cases of polydactyly, imaging tests may be used to further evaluate the condition and determine the number and structure of the extra fingers or toes. These tests provide detailed images of the bones, joints, and soft tissues, allowing healthcare professionals to make accurate diagnoses and develop appropriate treatment plans.
X-Rays: X-rays are commonly used to visualize the skeletal structures of the hands and feet. They can capture images of the bones, joints, and any abnormalities present in the affected digits. X-rays help determine the type of polydactyly, whether it involves extra bones or simple duplication of existing bones.
Ultrasound: Ultrasound uses high-frequency sound waves to create images of the internal structures of the body. It can be used to examine the soft tissues, blood vessels, and joints of the affected digits. Ultrasound is particularly useful in assessing the presence of any associated abnormalities, such as vascular anomalies or joint deformities.
Magnetic Resonance Imaging (MRI): MRI is a non-invasive imaging technique that uses powerful magnets and radio waves to generate detailed images of the body’s soft tissues. It can provide a more comprehensive view of the structures surrounding the extra digits, including tendons, ligaments, and nerves. MRI is especially helpful in assessing the functional capabilities of the duplicated digits and detecting any associated anomalies.
Computed Tomography (CT) Scan: CT scans use a combination of X-rays and computer technology to produce cross-sectional images of the body. They can provide more detailed information than X-rays alone and may be used in certain cases of polydactyly to assess the internal structures and confirm the diagnosis.
Overall, imaging tests play a crucial role in the evaluation and management of polydactyly. They help healthcare professionals determine the extent of the condition, identify any associated abnormalities, and guide the decision-making process regarding treatment options.
Treatment Options for Polydactyly
Polydactyly is a congenital condition characterized by the presence of extra fingers or toes. The treatment options for polydactyly depend on the specific type and severity of the condition.
When it comes to genetics, polydactyly can be inherited in different ways. It can be passed down from a parent who also has polydactyly, or it can occur sporadically without a family history. Genetic counseling can be helpful in determining the likelihood of passing on the condition to future generations.
In some cases, polydactyly may not require any treatment, especially if the extra finger or toe is small and not causing any functional or cosmetic issues. However, if the extra digit is causing difficulties with movement or interfering with functionality, surgical intervention may be considered.
Surgical treatment for polydactyly involves removing the extra finger or toe. The surgery is typically performed in infancy or early childhood to optimize the chances of restoring normal function and appearance. The procedure may also involve reshaping the remaining digits or addressing any associated abnormalities.
During the surgical procedure, the surgeon will carefully assess the anatomy of the hand or foot and make the necessary adjustments to achieve the desired outcome. After surgery, rehabilitation and physical therapy may be recommended to promote optimal healing and help the individual regain full use of their hand or foot.
It is important to note that the decision to undergo surgical treatment for polydactyly is a personal one and should be made in consultation with a healthcare professional. They can provide guidance and support, discussing the potential risks, benefits, and long-term outcomes of the procedure.
In summary, treatment options for polydactyly depend on the type and severity of the condition. While some cases may not require treatment, surgical intervention can help restore normal function and appearance in individuals with more significant polydactyly. Genetic counseling can also be beneficial in understanding the inheritance patterns and making informed decisions about family planning.
In cases where polydactyly causes functional problems or significant aesthetic concerns, surgical intervention may be pursued. The decision to undergo surgery is typically based on the severity of symptoms and the impact on the individual’s quality of life.
There are different surgical procedures that can be performed to correct polydactyly. The specific technique used depends on the type and extent of the extra digit.
One common procedure is called syndactyly release, which involves separating fused digits. This can be done through excision of the tissue connecting the digits or through skin grafting to cover any resulting gaps.
In cases of preaxial polydactyly, where the extra digit is located on the thumb side of the hand or foot, surgical intervention may involve removing the extra digit and reconstructing the remaining digits to achieve a more normal appearance and functionality.
Following surgery, it is important to follow the post-operative care instructions provided by the surgeon. This may involve keeping the affected area clean and dry, avoiding certain activities that could strain or disrupt the healing process, and attending follow-up appointments to monitor progress and address any complications.
