Treatment of hip impingement syndrome Hip impingement syndrome is a common condition that can cause chronic hip pain and limited hip flexion and internal rotation, and is a common cause of hip osteoarthritis. Typical signs of hip impingement syndrome: pain deep in the front of the hip joint, limited or painful internal rotation of the hip joint, and popping or discomfort in the hip joint, often aggravated by movement. Walking on a level path and straight flexion may be tolerated, but impact activities (e.g., walking on inclined paths or stairs, rotational movements) usually increase the pain. Pain may occur when standing up suddenly after sitting for a long time, when putting on shoes and socks, and when cutting toenails. The primary goal of treatment is to reduce the frequency of the associated symptoms, which includes avoidance of symptom-provoking postures. The second objective is to improve the range of motion of the joint as long as the pain is tolerable. Braking and nonsteroidal anti-inflammatory drugs are first used to treat symptomatic hip impingement syndrome. Exercise therapy is also commonly used, but first it is important to fully understand the hip deformity and the effect of the deformity on the range of motion of the hip and the muscle strength of the joint-related muscles. Improving the range of motion of the hip is not the goal of treatment. The long-term efficacy of conservative treatment of hip impingement syndrome is unknown. Surgery Surgery may be considered if symptoms do not improve with conservative treatment. Preparation for surgery includes evaluation of acetabular glenoid labral cartilage pathology and bony deformity of the acetabulum and proximal femur. The outcome of treatment is usually related to the degree of degeneration of the articular cartilage. Hip impingement syndrome is now generally treated by incisional surgery and/or hip arthroscopy, both of which have better early results and fewer complications. The selection of the right patient has an important impact on the outcome of hip impingement syndrome. The surgical treatment of symptomatic hip impingement syndrome focuses on the acetabular labral lesion and the corresponding bony deformity of the hip joint. The scope of surgery includes the central compartment (acetabular rim, acetabular glenoid labrum, and acetabular cartilage) and the peripheral compartment (femoral head-neck junction). The current surgical dislocation technique for hip impingement syndrome offers major advantages: wide field of vision, thorough cleanup of the lesion, ability to manage a variety of special conditions, no serious complications, and no need for special instrumentation. Many studies have shown better results with glenoid labral repair and resection of the bony deformity site.
