Congenital Hand Anomalies: Syndactyly & Polydactyly Treatment
A clear guide to congenital hand differences in children, including webbed and extra fingers, and the surgery that improves hand function.
Treatment usually begins with
Paediatric Assessment
Corrective Surgery
Hand Therapy
Surgical correction is typically planned in the first few years of life to support normal hand growth and function.
You may need this evaluated if...
An evaluation is recommended when these are noticed at birth or in early childhood:
- Two or more fingers joined together (webbed fingers)
- An extra finger or thumb
- Fingers that are unusually short, curved or fused
- Difficulty with grip as the child grows
Congenital hand differences are treatable, and timely surgery supports normal hand growth and function as the child develops.
What is Congenital Hand Anomalies (Syndactyly & Polydactyly)?
Congenital hand anomalies such as syndactyly (webbed fingers) and polydactyly (extra fingers) are differences present from birth in how the hand's fingers form.
Present from Birth
These differences occur during early foetal development of the hand.
Timing Matters for Growth
Surgery is usually planned at an age that balances technical ease with supporting normal hand development.
Function and Appearance
Correction aims to improve both how the hand works and how it looks.
Family-Centred Care
Parents are closely involved in planning the timing and approach to surgery.
Common Signs
- Fingers joined by skin or soft tissue
- An extra digit on the hand
- Uneven finger length or curvature
- Reduced grip development compared to peers
What Increases Your Risk
A combination of medical, genetic and lifestyle factors can increase the likelihood of this condition.
How It Is Diagnosed
A detailed clinical examination confirms the diagnosis and helps plan the right reconstructive or aesthetic approach.
Clinical Examination
Identifies the specific type and extent of the hand difference.
X-ray Imaging
Assesses the bone structure involved, which guides surgical planning.
Genetic Counselling (Selected Cases)
Offered when the anomaly is associated with a broader genetic condition.
Treatment Approaches
Conservative Care
- Observation for very mild variations
- Developmental monitoring of hand function
- Parent education on timing of surgical options
Surgical Care
Surgery separates webbed fingers or removes an extra digit and reconstructs normal hand contour, timed to support the best functional and cosmetic outcome as the child grows.
Treatment decisions are based on the extent of the condition, your goals and overall health, not a single test.
Know When to Act
Recognising these signs early and acting promptly leads to better functional and aesthetic outcomes.
Book an Assessment
Schedule a consultation for a routine evaluation or ongoing concern.
- A hand difference noticed at birth needing evaluation
- Planning the right age for corrective surgery
Seek Urgent Care
Reach out for emergency care immediately if you notice any of the following.
- Reduced blood flow to a finger noticed after birth
