Oblique supporting ligament reconstruction

The gooseneck 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 straightening dysfunction. For the rheumatoid arthritis, cerebral palsy formed by the goose neck deformity, the impact of the function is very large, we must 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. Curing disease: Indication Oblique support ligament reconstruction is applicable to: For the rheumatoid arthritis, cerebral palsy formed by the goose neck deformity, the impact of the function is very large, we must 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 hockey stick incision from the dorsal side of the distal interphalangeal joint, cross the joint from the ulnar side, cut to the proximal end along the medial line of the temporal side, and begin at the proximal phalanx of the proximal interphalangeal joint. The side is chamfered straight to the root. The neurovascular bundle is free, and a tunnel is made behind it, which is in front of the bone fiber tube and obliquely across the proximal interphalangeal joint. 2. Transcutaneously through the bone round needle, the distal interphalangeal joint is fixed in the extension position. The oblique round needle is obliquely fixed, and the proximal interphalangeal joint is fixed at a flexion position of 10° to 15°. 3. Take a 4mm wide graft from the longus or diaphragm. The distal end is implanted into the phalangeal base or sutured with the residual sputum, and is pierced from the fingerbone with a 4-0 stainless steel wire and fixed on the button. Pull out the wire from the back side to the outside of the skin. The transplanted tendon is guided by the medial vascular nucleus of the medial knuckle, and then the anterior interphalangeal joint is slanted across the joint in front of the bone fiber tube, leading to the groove next to the bone fiber tube on the proximal ulnar side. Sewing with the edge of the bone fiber tube with a non-absorbent suture under mild tension.
