Patient: examination and laboratory tests: left forearm stabbing injury: median nerve, ulnar nerve radial carpal flexor tendon, palmaris longus tendon, ulnar carpal flexor tendon, thumb longus flexor tendon, superficial flexor tendons of the index, middle, ring, and little fingers, showing: rupture of the deep flexor tendons of the middle, ring, and little fingers, partial rupture of the rotary anterior muscle; open comminuted fracture of the distal ulna. Treatment: median nerve and ulnar nerve. Each ruptured tendon was repaired with 3_0 Priligy sutures one by one. Medical history: It has been four months and the palm of the hand is numb. No sensation in the fingers. The palm of the hand can be basically extended. Palm grip. Can’t hold the fingers together. Can grip objects such as cups tightly. Tendons are partially adherent and there is significant muscle atrophy in the palm. Now I have been eating again, and potassium is estimated to be pressed. What can be done to treat it more obviously. Or what recipe. Or… Anyway good way. Doctor: The role of rehabilitation is very important in the recovery process after nerve and tendon injuries. In the early stages of peripheral nerve injury repair, the doctor will apply a cast brake according to the location of the nerve, in order to prevent the nerve repair site from being subjected to the pulling force, so as not to affect the regeneration of nerve tissue. 3-4 weeks later, the cast can be released after gentle passive activities to restore the function of the adjacent joints, but not excessive, in order to feel a slight pain at the site of injury as a principle, generally 20-30 minutes per activity After the activity, it should be protected with a cast, generally until 6-8 weeks after surgery, the specific time should be determined by the treating physician or rehabilitation physician. Good range of motion of the joint should be restored as soon as possible after full motion is allowed. For the muscles in the innervation area, active activities should be carried out, such as fist clenching, finger clenching, and palm to palm exercises, insisting on one action for 5-10 seconds, then relaxing for 5 seconds, and then repeating, 10-12 times as a group, 3-4 groups per day; for those who cannot move at all, biofeedback training or functional electrical stimulation (special machines are needed) can be carried out, which can prevent muscle atrophy and promote the recovery of nerve function, and should be Long-term persistence. Medication can be supplemented, in addition to oral meconium chloride, nerve growth factor can also be injected intramuscularly 3-4 times a week. The early stage after tendon injury repair should also be fixed in a cast so that the tendon at the injury site is in an unstressed state. Since adhesions can occur very quickly after tendon injury repair, it is recommended to start active and passive functional activities earlier, usually one week after surgery to start passive stretching by uncoupling the cast, and to continue to use the cast for protection after the activity. If the tendon injury is combined with a nerve injury, the time when activity can be started depends on the time allowed after the nerve injury is repaired. Active and passive stretching of the adherent tendon should be performed daily, combined with functional bracing if necessary. In conclusion, rehabilitation must be done early, properly, and with long-term persistence in order to see results.
