Bilateral medial canthal fixation repair

Bilateral medial malleolus repair is used for corrective treatment of internal hemorrhoids. Acute traumatic interpupillary widening combined with obvious nasal wall fracture and bilateral patellar tendon ligament need early fixation. Curing disease: Indication 1. Injury of the medial malleolar ligament such as impaired intercondylar widening and dislocation. 2, benign tumors caused by sputum displacement such as hemangioma, neurofibromatosis and bone fiber abnormal proliferation. 3, congenital craniofacial deformity such as widening of the distance, narrow cleft palate, craniofacial hypoplasia and hypoplasia of the mandibular surface. Contraindications The absence of internal or external defects after trauma or tumor resection is beyond the scope of this section. Preoperative preparation 1. The surgical plan should be designed according to the reasons for the displacement of the sputum. It is often used for internal and external hernia repair while treating major diseases. 2, in the sacral fixation, if you need to use small bone pieces or slotted wire, you should determine the bone site or prepare the metal material. Surgical procedure 1, surgical approach It can be done by locally damaging the wound or a small transverse incision in the surface of the ligament in the medial malleolus. 2. Exploring and identifying the medial malleolar ligament It may still be attached to the bone, or it may have been torn, or even mixed with the wound scars of the department. Sometimes it is necessary to separate and retain part of the scar tissue at the site corresponding to the medial malleolar ligament, acting as the medial malleolar ligament. 3, internal iliac ligament reduction and fixation The fixed fine wire is surrounded and passed through the ligament. In order to thread the wire to the opposite side, the wire is passed through the nose with a nose drill. In the case of a few emergencies, initial bone grafts help to fix. The rib graft graft is shaped according to the curvature of the inner wall of the crucible and fixed with a wire. This method ensures the solid bone fixation inside the medial malleolus when there is severe bone destruction or rupture. The increased bone graft provides stability without any external fixation. The wire is passed through the same bone graft on the opposite side and the contralateral free medial malleolar ligament is sewed and then tightened to the extent that correction is needed to provide a secure fixation of the traumatic ankle widening. Coronal incision approach: Coronal incision pathway is beneficial to the loosening of the sputum content in the severe displacement of the combined eye or in the correction of the widening of the intercondylar distance while correcting the internal hemorrhoids. After the suture is placed at the ligament, the tension applied to the wire depends on whether the tension on the upper and lower branches of the medial malleolus is equal. Pay attention to whether it is symmetrical after fixing. This is especially important in the correction of the widening of the interpupillary distance because a large amount of soft tissue is pulled into the opposite side. After the bone incision in the intercondylar widening correction is completed, the ends of the sharpened wire are passed from the subcutaneous site through the periosteum and soft tissue to the bone. complication 1. Wound infection. 2, the main reason for the recurrence of sputum displacement is the use of thin metal wire as the puncture and suture of the patellar ligament; secondly, the suture is unreliable, so that the patellar ligament is in a tight, fixed position, avulsion or fracture occurs; The two bone holes for the wire are too close, and the bone is absorbed after the ligation to loosen the fixation.
