Thumb metacarpophalangeal incision and reduction

There are two types of bone and joint dislocations: traumatic dislocation and habitual dislocation. Traumatic dislocation is the result of violence acting directly on normal bones and joints, such as playing football and football. Traumatic dislocations can be divided into upper dislocations and outward dislocations, while habitual dislocations are often the result of congenital anomalies or traumatic dislocations that are not addressed in a timely manner. Pathological change The pathological change of the upward dislocation of the bone and joint is the complete rupture of the patellar ligament, while the pathological change of the lateral dislocation of the bone and joint is the avulsion of the knee capsule from the attachment of the inner edge of the bone joint. Medial part of myofascial dilatation: There can be avulsions at the points and attachment of the medial femoral muscle. Bone joints are usually dislocated laterally, and sometimes bone and cartilage debris fall into the knee joint cavity to form a free body. May also be accompanied by meniscus and medial collateral ligament damage. Habitual dislocations often include congenital factors, such as osteoarticular and femoral condylar dysplasia and knee valgus. Wiberg divides bone and joints into three types according to the length of the osteoarticular and lateral articular surfaces: The length of the articular surfaces on both sides is almost equal, the medial articular surface is slightly depressed; type II, the length of the lateral articular surface is significantly longer than the medial, and the medial articular surface is still depressed; type III, the lateral articular surface is parallel, and the medial articular surface is short and convex, Nearly rectangular. Type II bones and joints are prone to dislocation. At present, the safest and most effective method for treating bone and joint dislocation is open reduction.
