Artificial joint replacement
Minimally invasive artificial hip replacement
Hip replacement with endoprostheses has been applied for over 50 years with very good results. In recent years, further development has led to minimally invasive operations, which spare the tissue. The method that we use, anterior minimal invasive surgery, permits the insertion of an artificial joint without cutting the ligaments or the muscles. The goal is a more rapid postoperative recovery of the patient with good long-term results.
The joint is surrounded by a capsule and forms a unit. Around that, there is a thick layer of muscle that is responsible for stability and active movement. Two natural gaps in the muscle exist on the front side, which can be used by the operating physician as an entrance path for minimally invasive operations. In this procedure, no muscle need be cut or disconnected.
The operation takes place under full anesthesia and is connected with an inpatient stay of 7 to 10 days. The operation itself lasts for one to one and a half hours. Depending on the size and weight of the patient, the scar measures between 8 and 12 centimeters. After the joint is open, the femoral neck is pushed to the side. The joint socket is then milled and the non-cemented joint implant is inserted. Then the femur is filed and, depending on the quality of the bone, the shaft prosthesis is inserted with or without bone cement. After intra-operative testing of the stability, the artificial head of the hip is replaced and the wound is then closed.
In the normal case, full weight-bearing is allowed immediately. Crutches for movement stability are used, if needed, for a few days. For the first 4 weeks after the operation, treatment with injections of heparin is necessary for reducing the risk of thrombosis. The ongoing healing treatment can be performed either on an outpatient or inpatient basis.
