Cleft hand, also known as split hand deformity or ectrodactyly, is a rare congenital condition characterized by a deep cleft or split in the center of the hand. This results in the absence or underdevelopment of one or more central fingers, giving the hand a claw-like or lobster-claw appearance. The condition can affect one or both hands and varies widely in severity, from a mild notch in the hand to a complete absence of the middle digits.
The cleft in the hand occurs because of a failure in the normal development of the central rays of the hand during embryonic growth. This anomaly can affect the bones, muscles, tendons, and skin, leading to functional and cosmetic challenges.
Cleft hand is primarily a congenital malformation, meaning it is present at birth. The exact cause is often unknown, but it is believed to result from a combination of genetic and environmental factors that disrupt normal limb development during early pregnancy.
Cleft hand deformities are classified based on the extent and pattern of the cleft and the involvement of bones and soft tissues. The most commonly used classification is the Manske and Halikis classification, which divides cleft hand into:
The primary visible symptom of cleft hand is the characteristic split or cleft in the palm, often accompanied by missing or fused fingers. Other features may include:
The severity of functional impairment depends on the extent of the deformity and the presence of associated anomalies.
Cleft hand is usually diagnosed at birth through physical examination. The distinct appearance of the hand makes the diagnosis straightforward. However, further evaluation is necessary to understand the full extent of the deformity and plan treatment.
If a hereditary syndrome is suspected, genetic counseling and testing may be recommended to identify specific gene mutations and assess the risk for future pregnancies.
The management of cleft hand focuses on improving hand function and appearance. Treatment is highly individualized based on the severity of the deformity, the patient’s age, and functional needs.
Surgery is the mainstay of treatment for cleft hand and aims to:

ional loss. As a surgeon trained in microsurgery, our approach includes:
With appropriate treatment, many individuals with cleft hand achieve good functional use of their hands. Early surgical intervention combined with therapy can significantly improve hand strength, dexterity, and appearance.
However, some limitations may persist, especially in severe cases. Psychological support and counseling can be beneficial to address self-esteem and social challenges related to the visible deformity.
Children and adults with cleft hand can lead full, active lives. Support from healthcare professionals, family, and community resources plays a crucial role in their development and well-being.
Cleft hand is a rare congenital condition characterized by a split or cleft in the hand due to missing or underdeveloped central fingers. It results from genetic and environmental factors affecting limb development. Diagnosis is made through physical examination and imaging, with genetic testing in some cases. Treatment involves surgery and therapy to improve function and appearance. With proper care, individuals with cleft hand can achieve good hand function and quality of life.
