posterior ankle capsulotomy

Posterior tibial articular capsulotomy is a surgical procedure used to treat ankle joint disease. In the case of severe plantar flexion, the residual plantar flexion after correction and the extension of the Achilles tendon can be corrected after the incision. However, the bone has been deformed and is invalid. Non-surgical treatment failure, more than 6 months after birth or older untreated patients require surgery. Treatment of diseases: sprained ankle Indication Non-surgical treatment failure, 6 months after birth or older untreated patients require surgery. Contraindications The patient is too old and should be filled with poor general condition. Preoperative preparation 1. Soak and clean the skin before surgery. Treat sputum. 2. Take a picture of the x-ray of the foot to understand the displacement and deformation of the bone joint. 3. Practice foot valgus before surgery, and loosen the inner skin. Surgical procedure 1. Position: side prone position. 2. Exposing and prolonging the Achilles tendon: with the Achilles tendon extension technique. Stitching the Achilles tendon should be performed after the posterior joint capsule is incision. 3. After the joint capsule is exposed: the Achilles tendon is cut off, and the long and short tendon tendons are pulled outward to the outside, and the posterior tibial vascular bundle, the posterior tibial tendon and the flexor longus tendon are pulled inward to reveal the sputum. The posterior joint capsule of the joint and the heel joint. 4. After the incision of the joint capsule: the back of the humerus is touched downward, and the foot is flexed and flexed, the posterior joint capsule of the ankle joint can be determined, and the transverse joint is cut open under direct vision, and the posterior iliac ligament is cut off when needed. For older children, the posterior capsule of the joint is often contracted, and can be cut transversely. If necessary, the posterior part of the ligament and the posterior cruciate ligament of the posterior triangular ligament in the medial and lateral anterior ligaments are cut off. Strong flexion of the ankle joint, while pressing the calcaneal nodules to fully separate the posterior joint capsule to correct the plantar flexion deformity. 5. Extend the Achilles tendon: Fit the upper and lower halves of the Achilles tendon to the proper tension while maintaining a 10° dorsiflexion. 6. Suture, external fixation: maintain the dorsiflexion of the foot, suture the incision according to the layer. The ankle joint was flexed at 10° and the heel was gently valgus fixed with a plaster cast. complication Toe blood supply.
