Open reduction of the displaced T-shaped acetabular fracture has a problem of accuracy of the fracture reduction. This study was carried out to demonstrate that the reconstruction of the pelvic brim by approaching the pubo-acetabular fragment plays a role in the accuracy of the reduction of displaced T-shaped acetabular fractures. From 1975 to 1990, a retrospective study was carried out of 22 patients who sustained a displaced T-shaped acetabular fracture. The patients were operated on by open reduction and internal fixation of the ischio-acetabular fragment to the posterior column without restoration of the pelvic brim. Radiographs of the pelvis were reviewed. The result showed that there was displacement of the pubo-acetabular fragment including the medial wall in all cases. As the result of this study, a prospective study between 1990 and 1997 was carried out of 15 patients who sustained displaced T-shaped acetabular fractures including 3 cases with medial displacement of the femoral head. The pubo-acetabular fragment was anatomically reduced and fixed to the anterior column of the acetabulumn as the first approach to restore a disrupted pelvic brim. There, patterns of the acetabular fracture were subsequently re-evaluated especially the ischio-acetabular fragment including the position of the femoral head by using an intraoperative portable X-ray technique. The stability of the hip joint was assessed by hip flexion. The intraoperative radiograph appearances of the ischio-acetabular fragment were visually confirmed by a second surgical exposure. The results showed that the intraoperative radiographs gave spontaneous reduction of the ischio-acetabular fragment in all patients except one. There was a reduction of the displaced femoral head into the hip socket in the three patients. The hip joints were stable in all patients. The second surgical exposure showed that there was good spontaneous reduction of the ischio-acetabular fragment to the posterior column by ligamentotaxis in 14 patients. Therefore, it is not necessary to address the ischio-acetabular fragment. In the exceptional case, the ischio-acetabular fragment was displaced as a free bone which could not be reduced by ligamentotaxis. However, reduction and internal fixation of the ischio-acetabular fragment to the posterior column for complete re-application of the hip joint onto the pelvic ring of this case was facilitated. Postoperative 2 year and 5 year follow-up showed that the fracture had healed without heterotrophic ossification or premature osteoarthrosis of the hip joint. The exceptional case had a broken plate at the anterior column of the acetabulum. Hip function was evaluated clinically using Merle D' Aubigne's hip score. All patients had a "very good score". The study showed that reconstruction of the pelvic brim by anatomical reduction and fixation of the pubo-acetabular fragment to the anterior column plays an important role in the accuracy of fracture reduction of a displaced T-shaped acetabular fracture.

From January 1997 to August 1998 all stable and nonstable trochanteric femoral fractures (n = 72) were treated routinely by gamma nail using the correct operative technique. Patients showing additional osteoarthritis of the hip in radiographs hip replacement was performed by a cementless modular femoral hip prostheses from January 1996 to August 1998 (n = 28). Follow up period was 6 to 18 months. Operation time and blood loss were higher using the prostheses. However complications and lethality (< 5%) were not different during postoperative course. In each group three operative technical complications occurred. Using a modified Harris Hip Score (without range of motion, contractions) the score was decreased non significant comparing both groups first of all in unstable fractures until follow up. In each group one revision (loosening of prostheses, excessive shortening of femoral neck) was necessary. Using the correct operative technique, the gamma nail proved to be a save device with good outcome. Outcome using modular prostheses is comparable to gamma nail. Therefore the use of modular prostheses is justified in case of osteoarthrosis and in some cases of very unstable fracture.

Current treatment for femoral head avascular necrosis has shown good results in early stages of disease, but are not as impressive after progression to collapse. We treated 19 patients (20 hips) with Stage III avascular necrosis (AVN) by open reduction augmented by methylmethacrylate cementation. Follow up ranges from 6 months to 2 years (average = 8.7 months). We followed patient progress with pre- and post-operative Harris Hip Scores, Womac Osteoarthritis Index and a Health Status Questionnaire (SF36). All patients realized immediate post-operative pain relief and improvement in function. Harris Hip, Womac Osteoarthritis Index and SF36 physical health scores improved significantly from 54.0 to 79.5 (p < 0.05), 54.3 to 29.8 (p < 0.05) and 28.4 to 42.4 (p < 0.05), respectively. Three patients had a conversion to total hip arthroplasty. Cementation is technically simple, burns no bridges and enables patients a rapid recovery. The long term results, in regards to progression of disease and secondary arthritis, are unknown.

The Swedish National Total Hip Arthroplasty (THA) Register was initiated in 1979, and it is one of the oldest quality registers in the world. The register covers all hospitals in Sweden, and today it contains > 205,000 hip arthroplasties. The failure endpoint definition in the register is revision. There is no information about quality of life and mortality. The aim of this study was to validate the results presented by the Swedish THA register by comparison with the Discharge register (the Swedish National Board of Health and Welfare) and to study mortality after hip arthroplasties. All hip arthroplasties from the Discharge register, performed in 1986 and thereafter, were compared with the Swedish THA register. Epidemiologic parameters, including mortality, were documented from the Swedish Death register. The mortality for primary THAs for men was 1% higher and for women 6% higher when compared with an age-matched and sex-matched cohort. For revision, the numbers were 7% and 9% higher. The risk for death compared with an age-matched and sex-matched population was lower for patients with osteoarthrosis treated with hip arthroplasty. The results with revision as failure endpoint showed that the Swedish THA register is reliable. The register includes >95% of the primary and revision THAs performed in Sweden between 1986 and 1995.

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.

During the past 40 years, improvements have been made in the technique, implant, and surgical environment for total hip replacement, which today is one of the most cost-effective operations done. The aim of this study was to compare different outcome measurement methods and to develop recommendations for optimal followup of total hip replacement. The study involved the outcome of 2604 randomly selected patients in Sweden treated surgically with a modern technique. General questionnaires (the Medical Outcomes Study 36-Item Short-Form Health Survey and the Nottingham Health Profile) were compared with disease-specific questionnaires (the Western Ontario and McMaster University Osteoarthritis Index and the Harris hip score). The study showed a good correlation between the studied questionnaires, and all questionnaires used could be suitable for followup study after hip replacement surgery. In clinical practice and for research, a general and disease-specific self-administered score should be used. Some patients (older and low cerebral capacity) have difficulties answering questions on these questionnaires. A new short self-administered general and disease-specific questionnaire was designed: the Total Hip Replacement score. The Total Hip Replacement score provides information about the result of the hip arthroplasty, and the results can be compared with results of other surgical interventions.

In this review, 18 studies have been evaluated about the effectiveness of exercise therapy in the physiotherapy in osteoarthritis of hip or knee. All studies emphasised the general profit of exercise therapy compared to alternative programs (such as "health education", etc.). The effect sizes were mostly indicated to be moderate to large. There were no study comparing two or more alternative exercise programs in regard to the size of effectiveness. Only two studies gave informations about the radiographic grade of the OA. Today the effectiveness is proved only for aerobic, dynamic strengthening exercises. There were no study about the effectiveness of physiotherapy in Hip-OA.

We evaluated the utility and the safety of arthroscopy for diagnosing and treating symptoms in patients with osteoarthritis (OA) of the hip. We studied 133 patients consecutively treated for hip OA, using a modified Harris Hip Score (HHS) for the clinical assessment: There were no related complications or infections. At an average follow-up of 18 months, 61% of patients showed an improvement of their preoperative score, although only 36% of those actually presented good or excellent results. The remaining 39% of the total, either developed recurrent symptoms or underwent a major surgical procedure after arthroscopy. Benefit derived from the arthroscopy procedure depends strictly on either age or OA severity. Arthroscopy of the hip joint is a safe tool for managing problems related to OA of the hip. Careful selection of patients must be performed to identify those who will benefit most from the procedure. It seems that young patients with early OA are those associated with a higher rate of procedure success.

This study reports the results of a battery of physical function tests used to assess physical function of older patients with clinical knee and/or hip osteoarthritis (OA), and the correlation to the WOMAC Index (disease-specific questionnaire). A total of 106 sedentary subjects, aged >60 years (mean 69.4, S.D. 5.9) with hip and/or knee OA (mean 12.2 yrs, S.D. 11.0) participated in the study. Mobility, joint flexibility and muscle strength were evaluated by recording time to: walk a distance of 8', ascend/descend 4 stairs, rise from/sit down from a chair (5 times). Hip/knee flexion and isometric quadriceps strength were also measured. Categories of performance were formed by dividing data into quartiles for each test (1=highest, 4=lowest score, 5=unable to complete) and, by summing the category scores, a total summary score (TSS) was obtained. The battery of physical function tests showed an acceptable test-retest reliability (ICC of all tasks > or =0.80) and internal consistency (Cronbach's alpha > or =0.80). Performance scores on walking, stair climb, chair-rise and ROM of affected OA joints were significantly correlated with each other, and with the WOMAC Index (P<0.05, Spearman's correlation). Lower scores on the TSS were associated with lower scores on all the WOMAC Index items (P<0.001). This study shows that a simple battery of physical function tests in combination with the WOMAC Index are reliable and may be useful outcome measures in the evaluation of therapeutic interventions and geriatric rehabilitation.

The authors used magnetic resonance imaging to evaluate the hip joint in patients with diastrophic dysplasia. T1- and T2-weighted images were obtained from 35 patients (25 female patients, 10 male patients) of different ages (1-39 years). The status of the joint and paraarticular soft tissues was evaluated. Hip joint congruity was good, although the joint was usually deformed. The thickness of the joint cartilage was diminished and signs of early osteoarthritis, including bone cysts and local edema, were common. The ligamentum teres was visible in only 24% of patients, suggesting abnormality of the ligamentous structures. Epiphyses were flattened or absent in all young patients. Of the 17 visible epiphyses, 7 showed avascular necrosis, indicated as a decrease in signal intensity in both T1- and T2-weighted images. It seems that proximal femoral epiphysis fails to bear normal weight pressure.
