Repair of medial canthal ligament avulsion or dissection

The avulsion or disconnection of the medial malleolar ligament causes the ankle angle to shift to the underarm, that is, the distal ankle deformity. Treatment of diseases: internal suede Indication The avulsion or disconnection of the medial malleolar ligament causes the ankle angle to shift to the underarm, that is, the distal ankle deformity. Contraindications The patient is too old and should be filled with poor general condition. Preoperative preparation 1. Rinse the lacrimal duct to understand the presence or absence of chronic dacryocystitis. If mucus purulent secretions are washed out, the lacrimal sac should be taken first. 2. X-ray examination should be done before operation to understand the local bone deformity and provide an important basis for the development of surgical plans. 3. Intranasal drip in the nasal cavity before surgery. Surgical procedure 1. A curved incision near the base of the nose for the skin of the medial malleolus, about 2 to 2.5 cm long. The soft tissue was separated down with a blunt hair cut to the tear bone and fully exposed. Removes local scar tissue, loosens scar tissue and all traction caused by other causes. Look for the ends of the medial malleolar ligament. 2. If the original ligament is found to be broken, it can be sutured with nylon suture or stainless steel thin steel wire. If a partial ligament break is found, the broken end of the ligament can be sutured to the residual medial malleolar ligament. 3. If the original sacral ligament stump can not be found, you can use the bone drill as the two bone holes in the back tears, 0.5cm apart, and try not to penetrate the nasal mucosa when drilling. 4. The stainless steel wire penetrates from one side of the bone hole, passes between the nasal mucosa and the bone wall, passes through the other side bone hole, and is sutured with a relatively tough connective tissue corresponding to the level of the internal hemorrhoid for twisting fixation. 5. Excision of excessive soft tissue and skin on the temporal side of the incision, suturing the orbicularis muscle and skin layer by layer. complication Wound infection.
