swanson surgery

The swan-neck deformity of the finger is named after the shape of the proximal interphalangeal joint extension and the distal interphalangeal joint flexion. The proximal metacarpophalangeal joint is sometimes accompanied by a straight dysfunction. Treating diseases: rheumatoid arthritis Indication Swanson surgery is suitable for: For the rheumatoid arthritis and cerebral palsy formed by the gooseneck deformity, the effect is very large, it is necessary to choose the timing of surgery, surgery in the stable period of disease. For most cases caused by trauma or burns, the choice is made for their pathology and patient needs, and attempts to restore or maintain joint activity while correcting deformities. Surgical procedure 1. Make a longitudinal incision in the midline of the finger side. The flexor digitorum tendon sheath was incision at the proximal interphalangeal joint, and the volar part of the joint capsule, the palmar plate, the short button and the periosteum were cut proximal to the joint. 2. Drill 2 small holes in the proximal phalanges from 0.5 to 0.6 cm from the palm to the back. Use a curette to scrape a rough surface between the 2 holes of the volcanic volar as the superficial flexor tendon attachment. The flexor digitorum tendon is also sharply scraped out of the rough surface, and the proximal interphalangeal joint is flexed by 20° to 40°, and the flexor digitorum tendon is fixed on the phalanx by extraction of the wire. The proximal interphalangeal joint was obliquely fixed with a thin round needle at a suitable flexion position, and the wound was sutured.
