Surgical Correction of Simple Cutaneous Syndactyly of the Third and Fourth Fingers in a Three-Year-Old Girl: A Case Report.

Syndactyly is a common congenital malformation of the hand, characterized by fusion of adjacent digits. Early surgical correction is recommended to prevent functional limitations and esthetic concerns. We report the case of a three-year-old girl with congenital simple complete cutaneous syndactyly between the third and fourth fingers of the left hand. The fusion was limited to soft tissues, with fully formed and separate fingernails. Surgical separation was performed using interdigital dorsal and palmar Z-plasty incisions, followed by full-thickness skin grafting harvested from the groin donor site. Postoperative recovery was uneventful. At follow-up, the patient demonstrated a normal range of motion, satisfactory esthetic results, and no evidence of web creep or joint stiffness. This case supports the effectiveness and safety of Z-plasty combined with full-thickness skin grafting for the correction of simple syndactyly in early childhood.
