ulnar nerve advancement in cubital tunnel syndrome

Elbow syndrome refers to the compression of the ulnar nerve of the elbow caused by various reasons. In the past, ulnar neuropathy was simply attributed to "ulnar neuritis" caused by elbow valgus. In fact, ulnar neuropathy is mainly a chronic injury secondary to the elbow. In 1957, Osborne determined the concept of ulnar nerve compression, called "late ulnar neuritis." The disease is more common in men than in women, mostly associated with chronic repeated strain and soft tissue degeneration in the elbow. Feindel and Stratford named the elbow ulnar nerve region "elbow" and named a series of syndromes with ulnar nerve symptoms in the region as "elbow syndrome". Treatment of diseases: ulnar nerve injury elbow joint tuberculosis Indication 1. Elbow joint trauma, osteoarthritis ulnar nerve sulcus bone hyperplasia, stimulation, compression and wear of the ulnar nerve. 2. The external humerus fracture combined with elbow valgus deformity, so that the tension of the ulnar nerve increases the numbness of the hand, the ulnar side of the ring finger, the pain, the touch, the temperature is reduced, the internal muscle atrophy, the grip strength is weakened. 3. Delayed ulnar neuritis caused by various reasons. Contraindications 1. Patients with severe heart, lung, liver, kidney disease and diabetes cannot undergo surgery. 2. People with potential infections in the body. Preoperative preparation One week before the operation, the patients were fed nutritious and digestible foods. Those with weak constitution can supplement the appropriate amount of protein and vitamins by oral or intravenous infusion. 3 days before surgery, routine orthopedic preparation, that is, on the first and second days, first wash the area with soapy water, disinfect the skin with iodine, ethanol and then use a sterile towel; on the third day, shave the hair, brush, disinfect and use Wrap the sterile towel. Carefully check the determined preparations before the operation. A sedative can be given that night to ensure a good sleep. Surgical procedure 1. The medial longitudinal incision of the elbow. 2. Cut the skin and peel off under the deep fascia. Pay attention to protecting the medial cutaneous nerve of the forearm. 3. Dissection and separation of the medial muscle space of the upper arm. 4. Cut off the medial muscle space. 5. Cut the flexor muscles from the starting point of the iliac crest and place the ulnar nerve forward under the muscle. 6. The flexor muscle group and the starting point are sutured with 4 needles to reconstruct the muscle origin. 7. The muscle starting point is rebuilt. 8, the muscle tunnel can pass the little finger. 9. Close the wound.
