First, the treatment of osteophyte and cystectomy is suitable for elderly patients. The treatment of hallux valgus is to add a tourniquet to epidural anesthesia or calcaneus interception anesthesia. Make an arc incision on the inside of the big toe joint to remove the skin with excessive thumb sac and pull the skin nerve under the incision to protect it from injury. What is the treatment method of thumb valgus? Expose the inside of the toe joint capsule, and cut the joint capsule with the tongue plate, with the tip pointing to the proximal metatarsal bone. Oblique metatarsal osteotomy is suitable for young and middle-aged patients with joint osteoarthritis without toes. The treatment of hallux valgus is double oblique osteotomy at the junction of head and neck far away from metatarsal bone, so that the anterior and posterior osteotomy are inclined and the inclined plane is 30 degrees. After osteotomy, the pure osteotomy line of the distal metatarsal is outward, and the cortical width is outward. Fix the medial side with a needle and bite open the proximal medial bony process. After 4 weeks of plaster fixation, you can try to go to the ground after the pain disappears.
2. Precautions 1. Diagnostic criteria of hallux valgus: the angle between the toe axis and the first metatarsal axis is greater than 15 degrees (usually less than 15 degrees), and the angle between the first metatarsal axis and the second metatarsal axis is greater than 80 degrees. 2. The operative age is related to the curative effect. Generally 10 ~ 20 years old is a good age. 3. The operation should try to avoid being related to the toe joint. 4. The operation to change the contact of articular cartilage of metatarsophalangeal joint will inevitably lead to the degeneration of articular cartilage, resulting in pain and stiffness of metatarsophalangeal joint. 5. Soft tissue surgery around joints will cause stiffness when joint capsule and ligament are involved. The degree of stiffness is directly proportional to the degree of damage. 6. When correcting hallux valgus deformity, the deformity of the big toe and metatarsal before rotation should be corrected at the same time. 7. If it is a beriberi patient, it is recommended to treat beriberi and perform surgical treatment to avoid postoperative infection. 8. Use prophylactic antibiotics after and during surgery. 9. People with a history of local purulent arthritis pain. This operation cannot continue.
To sum up, the outer sole of the thumb is flat, especially when the first metatarsal is varus and the piers of the first and second metatarsals are enlarged. If the metatarsophalangeal joint is round, the degree of thumb valgus is more serious, and wearing shoes is also an important reason for thumb valgus. The results show that wearing shoes increases the incidence of hallux valgus, and the toes and metatarsals are arranged in the same direction, and the feet are arranged in the same direction. If the situation is serious, you must seek medical attention in time.
