modified bosworth technique

Improved bosworth is used for the surgical treatment of tennis elbow. Tennis elbow is a common chronic injury to the elbow, which is more common in middle-aged people. There are many explanations for the etiology. Common sacral epicondylitis, ectopic synovitis, calcification of the extensor tendon, sacral nerve branch or forearm lateral cutaneous nerve branch, and the synovial edge of the ankle joint Hypertrophy, radial collateral ligament or annular ligament is stimulated. Because the beginning of the radial flexor tendon is in close contact with the external humerus, ankle joint, and annular ligament, any of these tissues will stimulate the muscle to produce symptoms. Tennis elbow can be cured by non-surgical treatment, including reduction of activity, physical therapy and partial closure. For those who are ineffective in conservative treatment, surgical treatment can be performed for the cause. The purpose of surgical treatment is to eliminate all possible pathological changes, including the removal of the proximal part of the annular ligament, the beginning of the release of the extensor muscle, the removal of the existing synovial sac and the edge of the synovium. Treatment of diseases: traumatic elbow arthritis Indication Improved bosworth is not effective for conservative treatment of tennis elbow for more than 6 months, and the pain is still severe. Preoperative preparation Prepare routinely before surgery. Surgical procedure Incision The posterolateral incision of the elbow joint was used to make a 7 cm long arcuate incision from the proximal side of the lateral epicondyle 2 cm. 2. Loose extensor tendon Cut the skin and subcutaneous tissue, cut the deep fascia at the proximal end of the extensor muscle 5 cm, sharply separate the tendon at the beginning of the external iliac crest, and retract it to the distal end, taking care to protect the ring attached to it. The ligaments do not enter the ankle joint. 3. Partial resection of the annular ligament and joint capsule Rotate the forearm, determine the ankle joint gap, make a transverse incision at 0.4cm in the distance and near each, starting from the anterior tibial incision, bypassing the humeral head outward, ending behind the ulna humerus incision, cutting a wide approximation 1.0 cm, which contains the proximal half of the annular ligament, the ankle joint capsule and its synovial folds. The distal portion of the annular ligament remains to stabilize the upper ankle joint. 4. Fixed extensor tendon The protrusion of the external epiphysis was excised with a bone knife, and the total extensor tendon piece was loosely sutured on the soft tissue around 0.5 cm distal to the distal end of the humerus. 5. Close the wound The deep fascia, subcutaneous tissue and skin were sutured intermittently with silk. Postoperative diet 1. Give high protein, high vitamin and cellulose-rich digestible diet. 2, do not eat spicy spicy food.
