Congenital upper limb deformities
Congenital hand deformities
Aphalangia

Aphalangia is the Congenital absence of a part or the entire digit of a hand or FOOT. It occurs As a result of primary developmental failure or amniotic band constriction. Clinical practice encounters cases where the nail phalanx or part of it is missing, and more rarely, the complete absence of a single finger or multiple fingers on one or both hands.

This anomaly is accompanied not only by a cosmetic defect, but also by impaired hand function. Therefore, children born with this condition undergo corrective Surgical Treatment aimed at improving hand function.

The Scope of surgical Procedures varies. Previously, finger phalangization combined with metacarpal resection was performed. With the advancement of microsurgery, specialized hand microsurgery departments have made it possible to perform vascularized second toe-to-hand autotransplantation to replace a missing thumb. Alternatively, if at least a portion of the bone phalanx is preserved, phalangeal lengthening can be achieved using a distraction device. Today, such procedures are performed very widely.
