proximal tibial incision

Proximal tibial incision is used for the treatment of thigh and knee deformity. Treating diseases: knee valgus Indication Proximal tibial incision is applicable to: 1. Severe knee flexion deformity, which was not completely corrected after osteotomy. 2, knee valgus, varus deformity or accompanied by rotational deformity. Surgical procedure 1. Incision: A 6- to 8 cm curved incision is made from the upper end of the lower leg to the inside or outside of the patellar ligament. 2. Cut the periosteum and expose the bone above the tibia to the lower part of the humerus. 3, osteotomy: According to the deformity and the habits of the surgeon, the following osteotomy method can be used: 1V shape. When the degree is heavier, the reverse side can be cut off a piece of bone, and after correction, the bone piece is cut and filled on one side of the mouth; 2 wedge shape. According to the size of the deformed angle, the wedge-shaped bone is cut off from the convex surface; The concave spherical surface is at the proximal end. All of the above methods are often unstable, and often require Kirschner wire for cross fixation, parallel compression or screw fixation. In order to avoid the above shortcomings, the incision is made above the attachment point of the humerus ligament of the tibial plateau, where the contact surface is large, the stability is strong, the displacement is not easy, and the internal fixation is not required.
