radial head resection

Radial head resection for the treatment of congenital dislocation of the humeral head. Congenital dislocation of the humeral head is rare. When the dislocation of the humeral head is long, the humeral head is small, and there is no evidence of ulnar fracture, the disease should be suspected. The X-ray shows that the humerus is long and the ulna is bow-shaped, corresponding to the humerus. The development of the small head is poor, and the humeral head of the proximal ulna is shallow or absent, and can be unilateral or bilateral. Treatment of diseases: congenital humeral head dislocation Indication 1. Congenital dislocation of the humeral head failed to be cut open early, or dislocated after reduction and reduction, which significantly affected the elbow flexion and extension function. 2. The patient has entered puberty, or the proximal humerus has closed. Contraindications Young children and elbow joint function are not affected, the operation time should be postponed to prevent the development of ulnar bone and dislocation of the ulnar joint. Surgical procedure Incision Starting from the external iliac crest, along the anterior border of the elbow muscle, the iliac crest of the proximal humerus to the proximal end of the ulna is about 5 cm long. 2. Expose and remove the humeral head Cut the skin and deep fascia, find the gap between the ulnar wrist extensor and the elbow muscle and cut it, and pull it to the sides to reveal the small head of the humerus. The longitudinal incision switch capsule is used to remove the residual annular ligament, and the level of the osteotomy is selected according to the length of the tibia overgrowth. If there is not much growth, it can be cut off in the neck. If the proximal humeral shaft should be removed, it should be removed together with the periosteum, but the deep branch of the phrenic nerve should be prevented. 3. Stitching joint capsule and muscle stop The elbow joint and the upper ankle joint capsule were sutured intermittently with silk thread, and the elbow muscle tendon was sutured to the original stop point, the tourniquet was relaxed, the bleeding was completely stopped, and the incision was closed layer by layer.
