Multiple dislocations after femoral head replacement consider improper exercise or loosening or fracture around the prosthesis, and take conservative treatment or surgical treatment for the cause of the disease. 1. Conservative treatment: If the dislocation is caused by improper exercise, it is necessary to strengthen the muscle strength training around the hip joint to increase the stability around the hip joint. Avoid large activities of the hip joint, avoid hip internal rotation or external rotation, avoid sitting on a short bench. 2. Surgery: For repeated dislocations that are ineffective through conservative treatment, the radiographs of the hip joint around the prosthesis loosening, fracture around the prosthesis or wear out the bone need to perform revision surgery. Repeated dislocations after femoral head replacement need to identify the specific causes for further treatment.
