split hand closure

Split hand closure is used for the surgical treatment of congenital split hand deformity. Congenital split hand deformity, also known as lobster claw-shaped hand deformity, is very rare in clinical practice. It is generally divided into two types. The first type is also called the center type, and the palm has a deep crack. The central part of the metacarpal bone is divided into two parts, usually one or several metacarpal bones are absent, and their corresponding fingers are absent, or with adjacent fingers. The second type is also called the middle hemiplegic side type. This type of deformity is heavy. The central part of the metacarpal and phalanx are lacking. It is often only necessary to keep two short fingers on the temporal side and the ulnar side. Because of the wide finger and force line anomalies between the remaining two fingers, the gripping and clamping functions are substantially lost. Surgical treatment should be performed when the sick child has obvious dysfunction after 2 years of age. The central type of split hand deformity adopts a repair operation to eliminate the crack of the palm, which can enhance the grip function of the hand and improve the appearance. The second type of treatment is more difficult and often requires a second-stage surgery to improve its grip function. Treatment of diseases: Pediatric hand-heart malformation syndrome Indication Split hand closure is suitable for congenital split hand deformity as the central type, aged over 2 years old, and affects the grip function of the affected hand. Surgical procedure 1. First form a rectangular flap at the palm crack. 2. Excision of excess skin on the volar and dorsal sides of the fissure, and removal of part of the adductor pollicis muscle, suturing the deep tissue, and then suturing the rectangular flap, so that the gap between the two fingers disappeared. The thumb column was temporarily fixed in the functional position with two Kirschner wires.
