Atypical Cleft Hand: Surgical Technique for Grasping Improvement

Introduction: We present 6 cases of children with atypical cleft hand and discuss a surgical technique. Clinically, participants presented with a lack of pulp-to-pulp pinch due to metacarpophalangeal ligament insufficiency and difficulty grasping large objects because of the narrowed first web. Materials and Methods: Second metacarpal resection and Z-plasty, creating a wide first web. The second extensor digitorum communis tendon was transferred to improve the thumb metacarpophalangeal joint stability. Conclusions: The surgical technique presented in this paper did improve function in oligodactyly or type-IIA atypical cleft hand.
