Congenital Hand Deformities: Treatment Options for Children

Congenital Hand Deformities: Treatment Options for Children

Congenital hand deformities are conditions present at birth that affect the structure and function of a child's hand. These conditions occur in approximately 1 in every 500 to 1000 live births and range from minor anomalies to complex malformations that significantly impact hand function. Early diagnosis and timely surgical intervention by an experienced plastic surgeon can make a profound difference in a child's ability to use their hands normally. Dr. Prasanna Somvanshi, a skilled plastic and reconstructive surgeon in Mumbai, specialises in paediatric hand surgery at NH SRCC and Surya Hospital, two of Mumbai's most trusted children's healthcare facilities.

Syndactyly: Fused Fingers

Syndactyly is one of the most common congenital hand deformities, occurring when two or more fingers are joined together by skin or, in more complex cases, by bone. It can be classified as:

• Simple syndactyly: Fingers are connected only by skin and soft tissue.
• Complex syndactyly: Bones of adjacent fingers are fused together.
• Complete syndactyly: Fusion extends to the fingertips.
• Incomplete syndactyly: Fusion does not reach the fingertips.

Surgical separation is typically recommended between 12 and 18 months of age. The procedure involves carefully dividing the shared skin and creating individual finger spaces using skin grafts or local flaps. Dr. Prasanna Somvanshi employs meticulous microsurgical techniques to preserve blood vessels and nerves, ensuring each finger has adequate circulation and sensation after surgery.

Polydactyly: Extra Fingers

Polydactyly refers to the presence of one or more extra fingers. It may occur on the thumb side (preaxial), the little finger side (postaxial), or in the central digits. Treatment depends on the complexity of the extra digit:

• Simple skin tags: Can sometimes be removed in the clinic during infancy.
• Well-formed extra digits: Require formal surgical excision with reconstruction of ligaments, tendons, and joints to ensure proper alignment and function of the remaining finger.

Dr. Somvanshi carefully evaluates each case with X-rays and clinical examination to determine which digit has better function and should be preserved. Surgery is typically performed between 6 months and 2 years of age at NH SRCC or Surya Hospital.

Thumb Hypoplasia: Underdeveloped Thumb

The thumb accounts for approximately 40 percent of hand function, making thumb hypoplasia a particularly impactful condition. It ranges from mild underdevelopment to complete absence of the thumb. Treatment options include:

• Mild cases (Type I-II): Tendon reconstruction and stabilisation procedures to improve thumb function.
• Moderate cases (Type IIIA): Reconstruction involving tendon transfers, joint stabilisation, and sometimes bone grafting.
• Severe cases (Type IIIB-V): Pollicisation, a procedure where the index finger is surgically repositioned and reconstructed to function as a thumb.

Dr. Prasanna Somvanshi has performed numerous pollicisation procedures with excellent functional and cosmetic results, allowing children to develop a strong, functional grip essential for daily activities.

Trigger Thumb in Children

Paediatric trigger thumb presents as a locked or clicking thumb that the child cannot fully straighten. Unlike adult trigger finger, which is caused by repetitive strain, the paediatric form is believed to be congenital, resulting from a size mismatch between the flexor tendon and its sheath. While some cases resolve spontaneously before age one, persistent trigger thumb typically requires a minor surgical procedure called A1 pulley release. This outpatient surgery takes approximately 15 to 20 minutes and has excellent outcomes. Dr. Somvanshi recommends surgery if the condition persists beyond 12 to 18 months of age.

When Is the Right Time for Surgery?

Timing of surgery is crucial in paediatric hand deformities. General guidelines include:

• Syndactyly: 12 to 18 months, especially if border digits (thumb-index or ring-little) are involved.
• Polydactyly: 6 months to 2 years, depending on complexity.
• Thumb hypoplasia: Usually around 12 to 24 months to ensure adequate tissue size for reconstruction.
• Trigger thumb: After 12 to 18 months if not resolving spontaneously.

Early surgery allows children to develop normal hand function during critical developmental milestones. Delayed treatment can lead to compensatory movement patterns that are harder to correct later.

Why NH SRCC and Surya Hospital?

Dr. Prasanna Somvanshi performs paediatric hand surgeries at NH SRCC and Surya Hospital because these facilities offer dedicated paediatric anaesthesia teams, child-friendly environments, and comprehensive post-operative rehabilitation services. These hospitals, along with SevenHills, HN Reliance, MRR Hospital, and Sushrusha Hospital, provide the multidisciplinary support essential for treating young patients with complex hand conditions.

If your child has been diagnosed with a congenital hand deformity, early evaluation is essential. Contact Dr. Prasanna Somvanshi to schedule a consultation and learn about the best treatment options available for your child in Mumbai.
