Kidner surgery

Kidner surgery is used for the treatment of flexible flat feet. The deformable flat foot, or loose flat foot, is characterized by the disappearance of the medial longitudinal arch at the time of weight bearing, and the longitudinal arch can return to a normal state when the weight is not loaded. In addition, there may be a talus protruding to the medial and temporal sides of the foot, the forefoot in the plane and achilles tendon plane abduction, heel valgus and Achilles tendon shortening. Treatment should be based on non-surgical treatments, such as using an arch pad or wearing orthopedic shoes to strengthen the muscles of the foot. Surgical treatment is considered only after symptoms such as pain are severe and non-surgical treatment is ineffective. Surgical methods should be based on the patient's condition, strict surgical indications. Treatment of diseases: flat feet Indication Kidner surgery is suitable for children under 10 years of age, due to the deformable flat feet caused by excessive protrusion of the scaphoid or the scapula, pain and other symptoms are not effective after non-surgical treatment. Contraindications Significant secondary changes have occurred in stiff flat feet or foot bones and soft tissues. Preoperative preparation Including skin preparation, suitable osteotome and other orthopedic instruments. Surgical procedure Use epidural anesthesia or general anesthesia. In the supine position, the balloon tourniquet is tied in the middle of the thigh. 1. Make a slightly curved incision in the medial aspect of the foot, starting from the lower side of the medial malleolus to the base of the first metatarsal. The deep fascia and periosteum were cut longitudinally, and the upper and lower sides were separated into two upper and lower sides. The attachment point on the dorsal side of the tendon after free tendon retains its attachment point on the side of the scaphoid and the cuneiform. 2. Use a thin narrow bone knife to cut the posterior tibial tendon along with the lamellae from the scaphoid bone, leaving only the distal end of the wedge bone. The posterior tibial tendon is then displaced laterally to the temporal sulcus of the scaphoid. If there is no bone groove, you can use a bone knife to cut a bone groove. Use the osteotome to remove the overhanging part of the scaphoid and the inner part of the scaphoid, so that it is flush with the talus and the cuneiform bone. 3. The posterior tibial tendon displaced to the side of the scaphoid was sutured and fixed on the periosteum and fascia of the temporal side. When suturing, the foot should be turned inward and the arch should be raised to maintain a certain degree of tension in the tendon. 4. Suture the periosteal fascia flap to cover the rough bone surface of the scaphoid and the posterior tibial tendon. 5. Suture the incision in layers. complication The main complication of Kidner's surgery was that the foot deformity was not corrected or the pain symptoms were not relieved.
