Multiple closed avulsions of flexor tendons of the hand caused by a firecracker blast

Closed avulsion, in the absence of pathology, of both flexor digitorum profundus and superficialis tendons from the same finger is uncommon. We report a multiple closed avulsion of long fingers flexor tendons, associated with pulleys rupture in the left hand of a healthy, 16-year-old boy. The lesion was caused by a firecracker blast which the patient had tried to hide. No injuries were found in the volar or dorsal areas of the hand. All affected flexor tendons were reinserted; in addition, second and third digits fourth annular pulleys were resutured to prevent posterior bowstringing. At present, the patient has completely recovered his range of motion and has obtained his driver license.
