Reconstructive Wrist and Finger Extension Surgery

Stretching and extension of the function of the wrist for the treatment of hand deformity, forearm extensor tendon caused by carpal ptosis and finger deformity, if the flexor and flexor muscles are good, and the ulnar, radial flexor carpal, palm long muscle, When the muscle strength of the anterior circular muscle is basically normal, the function of using the flexor muscle instead of the extensor muscle can refer to the treatment method of the tendon transposition of the sacral nerve sac, that is, the anterior circumflex muscle end point and the temporal extension of the wrist and the short muscle. The ulnar flexor carpal muscles were transferred to the extension of the total muscles, and the metacarpal muscles were transferred to the longissimus dorsi muscles, and the iliac crest muscles were retained in situ. Treatment of diseases: sacral nerve sensation Indication Stretching and extension of the function is suitable for the forearm extensor palsy, pronator or forearm flexor function. Surgical procedure 1. The incision should be made on the volar side to reveal the palmar long muscle and the ulnar flexor carpal muscle. The dorsal side is made to incision and suture the tendon. First, a 2cm transverse incision is made on the palm of the hand. 2. Exposure and free graft tendon reveal the palmar tendon and cut off at the stop point. A second incision of 3 to 4 cm in length was made from the middle of the forearm volar, and the severed palm length muscle was withdrawn from the incision and wrapped with a wet gauze. The wrist was stopped from the first incision and the wrist was removed from the second incision of the forearm, and wrapped in a wet gauze. 3. Turn the forearm to the pronator position, and make an S-shaped incision of 6~8cm in length at the proximal end of the dorsal side of the wrist, revealing the extension of the total muscle, the extension of the longbone and the abductor longus muscle tendon, so that the incision is made to both sides. The hypodermic tunnel passes through the second incision of the forearm. The palmar long tendon is passed through the temporal tunnel, and the ulnar flexor carpitenus is guided through the ulnar tunnel to the S-shaped incision for use. 4. After the tendon sutures and sutures the forearm volar incision, the forearm is in the neutral position, and the incision is made at the upper 1/3 of the temporal side of the temporal side to expose the diaphragm, and the muscle can be retracted to see the pronated round muscle located in the deep side. The flaky muscle is stopped, and the stagnation point is cut together with the periosteum of the tibia, and the proximal and distal sacral long and short muscles are sutured under a certain tension. 5. The wrist joint stretches 30°, the metacarpophalangeal joint and the interphalangeal joint are straightened, and the ulnar flexor carpal muscle is obliquely sutured on the total tendon of the extension finger. The long muscle of the palm is in the outer position of the thumb and the length of the thumb. The muscle is made into a braided suture.
