Two-Staged Tendon Reconstruction in Flexor Tendon Ruptures Secondary to Fracture of the Hamate Hook

초록

We report a case of 2-staged reconstruction of flexor tendons ruptured spontaneously by attrition. A 49-year-old man presented with inability to flex the ring and little fingers of his left hand. Preoperative computed tomographic scans revealed fracture of the hamate hook. At the time of the operation, both the flexor superficialis and profundus of the little finger and the flexor profundus tendon of the ring finger were ruptured adjacent to the fracture site of the hamate. Because the flexor tendon rupture secondary to the fracture of the hamate is extremely rare, and surgical outcomes of previous reports are not satisfactory, a decision was made to perform 2-staged reconstruction of ruptured flexor tendons. The surgical result was excellent with complete restoration of full range of motion. This report describes for the first time to our knowledge, the technique, and rehabilitation of 2-staged tendon reconstruction in a patient with hook of hamate fracture.
