Mayo surgery

Elbow joint stiffness and fibrous stiffness are limited by the movement of the metatarsophalangeal joints, and are mainly limited by back extension and pain, which affects normal walking. The cause of the disease may be trauma, exfoliative chondritis or osteochondritis, pronation foot and the first metatarsal is too long. The most common treatment methods are Keller surgery, first metatarsophalangeal joint fixation, Mayo surgery, and proximal phalanx dorsal wedge osteotomy. Keller surgery is effective in correcting deformities and relieving pain. Most of the effects of elbow joint stiffness and fibrous stiffness are satisfactory. Treatment of diseases: elbow joint stiffness and fibrous stiffness Indication Mayo surgery is the main reason for the elbow joint stiffness and fibrosis. The first metatarsal head has obvious bone hyperplasia to form the lip-like bulge, which causes the extension of the metatarsophalangeal joint and pain, which affects the walking function. Contraindications The first metatarsophalangeal joint is severely degenerative, the articular cartilage surface is extensively damaged, or the toe is severely deformed. Preoperative preparation Including skin preparation, osteotome, osteophytes and other orthopedic instruments. Surgical procedure 1. Do the incision of the dorsal aspect of the first metatarsophalangeal joint, starting from the middle of the proximal phalanx, extending backward along the medial aspect of the long extensor tendon, ending at the junction of the first iliac bone and the distal third of the junction. The long extensor tendon is retracted to the outside, and the switch capsule is longitudinally cut to reveal and comprehensively examine the condition of the metatarsophalangeal joint. 2. The toe is flexed and the first metatarsal head is dislocated to the dorsal side. Use a sharp bone knife to remove the epiphysis of the dorsal metatarsal head together with some normal bone, so that the metatarsophalangeal joint of the toe can at least passively extend back to 60°. For example, if there is a callus on the base of the proximal phalanx, it is also trimmed. The bone surface after excision of the epiphysis can be smoothed with the epiphysis. 3. Stitch the joint capsule and incision. complication The main complication of Mayo surgery was that the resection of the dorsal metatarsal head of the humerus was not accompanied by partial normal bone resection; or because of extensive destruction of the cartilage surface of the metatarsophalangeal joint, the back extension and pain of the toe were not significantly improved.
