Congenital Differences of the Hand

Congenital hand differences are conditions present at birth that affect the shape, function, or development of a child’s hand or upper extremity. These differences can range from very mild conditions that resolve with simple treatment to more complex reconstructive needs involving bones, joints, tendons, nerves, and blood vessels.

At the NYU Langone Center for Children’s Hand Clinic, Dr. Jacques Hacquebord provides expert, family-centered care for infants, children, and adolescents with all forms of congenital hand differences. Working closely with pediatric specialists, therapists, and plastic and orthopedic surgeons, Dr. Hacquebord offers comprehensive evaluation and individualized treatment plans designed to support each child’s growth, function, and confidence.

Pediatric Trigger Thumb
One of the most common congenital hand differences, pediatric trigger thumb, occurs when a tendon in the thumb becomes stuck, limiting bending or straightening. Many cases improve on their own, but some require a small, highly successful outpatient procedure to restore normal motion.

Thumb Duplication (Polydactyly)
Thumb duplication involves having two thumbs or duplicated thumb bones. Treatment is typically surgical and focuses on creating one stable, functional, and well-aligned thumb. Our team uses modern reconstructive techniques to optimize strength, appearance, and long-term function.

Syndactyly (Webbed Fingers)
Syndactyly occurs when two or more fingers are joined by skin or, in some cases, bone. Surgical separation is often performed in early childhood to improve hand function and allow fingers to grow normally. Dr. Hacquebord uses meticulous soft-tissue reconstruction to ensure safe separation and ideal cosmetic outcomes.

Thumb Hypoplasia
Thumb hypoplasia refers to an underdeveloped thumb, which may appear smaller, weaker, or unstable. Treatment varies depending on severity and may include ligament reconstruction, tendon transfers, or, in severe cases, pollicization—creating a new thumb from the index finger to restore strong pinch and grasp.

Radial Club Hand (Radial Longitudinal Deficiency)
A rare but complex congenital condition, radial club hand affects the radius bone and the alignment of the wrist and hand. These cases require multidisciplinary care, including early splinting, stretching, and staged reconstructive surgery to improve arm alignment, function, and growth.

Other Complex Congenital Differences
Dr. Hacquebord also treats a wide range of other congenital hand conditions, including:

• Cleft hand
• Arthrogryposis-related wrist and hand stiffness
• Constriction band syndrome
• Ulnar longitudinal deficiency
• Complex digit and limb anomalies requiring staged reconstruction

These conditions often benefit from coordinated care among pediatric hand surgeons, therapists, and specialists in limb reconstruction and microsurgery.

Families seeking treatment for congenital hand differences deserve clear guidance, reassurance, and a compassionate approach. Dr. Hacquebord emphasizes:

• Early diagnosis and individualized treatment plans
• Multidisciplinary care with pediatric therapy and orthotics
• Clear communication with families at each step
• Long-term follow-up to support growth, strength, and development

Our team understands that treatment decisions are deeply personal. We work closely with families to ensure each child receives the safest and most effective care possible.

As part of the NYU Langone Center for Children’s Hand Clinic, Dr. Hacquebord provides specialized expertise across the spectrum of congenital hand and upper-extremity conditions—from mild differences to the most complex reconstructive challenges.

Our mission is to help every child achieve the best possible function, independence, and quality of life.
