Arthroscopy of the hip joint has developed into a useful tool for the hip surgeon. Hip joint anatomy, however, makes special demands of the arthroscopist. He needs to be familiar with the arthroscopic anatomy of the hip and its variations. Moreover, he should have practical training in the technique of hip arthroscopy prior to his first intraoperative experience in order to avoid complications. A complete arthroscopic inspection of the hip can be achieved by using a combined procedure: whereas the central hip compartment can be scoped only by distraction of the joint, the periphery can be better seen without traction. Whether to place the patient supine or lateral is dependent on personal experience. No matter which position is used, the positioning technique has to be exact. The literature has shown that most complications are related to traction. Before the first portal is placed, the joint vacuum force should be broken by distension of air or fluid. This leads to maximum distraction of the joint and reduces the risks of damage to labrum and cartilage during first access to the joint. For a diagnostic round through the central compartment, at least two portals have to be placed. The use of a 3-portal technique increases the range of inspection. Due to the relatively thin soft tissue mantle and greater distance to neurovascular structures, the anterolateral or lateral portal should be used as the first portals to the central compartment. In addition, the anterolateral portal is the standard portal to the periphery of the hip. The posterolateral or anterior portal should be used as a supplementary portal. The following indications have been described for an arthroscopic procedure of the hip: loose bodies, labral lesions, synovial diseases such as chondromatosis and pigmented villonodular synovitis, associated lesions in underlying osteoarthritis, ruptures of the teres ligament, malorientation of the acetabulum and proximal femur and, last but not least, "idiopathic" hip pain. The use of hip arthroscopy in infectious arthritis, avascular necrosis of the femoral head, Perthes' disease, osteochondrosis dissecans and complications after total hip replacement is less frequent. Here, in addition to its diagnostic value, operative arthroscopy of the hip offers removal of loose bodies, resection of the labrum and ligaments, synovial biopsy, partial synovectomy, microfracturing, lavage and placement of intraarticular drainage. The first results of arthroscopic procedures in the hip are promising. In addition to its diagnostic value and contribution to the understanding of intraarticular anatomy and pathology, recent studies have demonstrated the advantages of the arthroscopic treatment of the hip.

Two-stage total hip arthroplasty (THA) is considered a safe choice for the treatment of primary infectious arthritis of the hip. In cases where the proximal portion of the femur is intact without infection, the use of a spacer with a femoral stem during the interim would disturb the normal femoral medullary cavity. The authors report the technical procedure and outcomes of cases using a novel medullary sparing, antibiotic-loaded hip spacer for the treatment of hip infections.Five consecutive patients (5 hips) with infectious arthritis of the hip were treated in a 2-stage approach using an intraoperatively made medullary-sparing hip spacer. During the first-stage THA, after thorough debridement of potentially infected and necrotic soft tissues, the spacer was inserted into the femoral neck and fixed without opening the femoral canal. Antibiotics were administered for at least 6 weeks and were continued until the infection was controlled clinically, after which the second-stage THA was completed.Infection was eradicated in all 5 hips. Average follow-up was 39.6 months (range, 30-59 months). At most recent follow-up, no recurrence of infection was observed. No specific complications were associated with the use of this novel spacer. Average Harris Hip Score improved from 35.2 (range, 28-43) before the first-stage THA to 61.6 (range, 54-71) between the 2 stages and to 93.6 (range, 89-99) at final follow-up. All patients ambulated with the aid of crutches during the interim period.
