The results of the first 56 consecutive total hip replacements using a new cementless, sandwich (alumina-polyethylene-titanium) acetabular component are reported. From March 1994 to March 1995 we operated on 39 female and 17 male patients; their mean age was 62.8 years (range 32-85 years). The Harris Hip Score was used for clinical evaluation. X-rays were examined according to the DeLee and Charnley method. At an average follow up of 62.4 months, 51 patients had complete clinical and radiographic data. For them, we recorded a good clinical result (average HHS 90.6), and we could detect no acetabular radiolucencies on X-rays. At the 5-year follow-up the results of this ceramic acetabular cup are quite encouraging. As a matter of fact, although the clinical results are very similar to those reported by other authors with conventional ceramic-polyethylene coupling prosthesis, the absence of periacetabular radiolucency and socket migration could mean less debris formation, less acetabular wear and, consequently, a longer life of the implant.

This study reports the results of total hip arthroplasty (THA) for osteonecrosis after failed free vascularized fibular grafting (FVFG) at a 5-year minimum follow-up. In this study, 73 patients (89 THA) were treated for failed FVFG, and survival of THA was discussed. Clinical outcome was measured using a pain and function survey (possible 91 points) in 84 hips and Harris Hip scores (HHS, 100 possible points) for 52 hips. Survival was 94.4% at 5 years, 85.4% at 10 years, and 82% overall. Average HHS at final follow-up improved to 77.5 (P <.05). The average clinical result after THA was 68 of 91 points. In this study, 58% of patients had a good or excellent HHS. The overall revision rate for proximal ingrowth stems was 13% at an average follow-up of 9.1 years. Only 4 patients required stem revision for loosening (7.4%). THA after FVFG provides improved functional results comparable to the published results of primary THA in osteonecrosis in young patients.

We investigated the long-term changes in the Harris Hip and Knee Society scores (HSS and KSS) to determine whether they result from overall functional decline rather than actual changes in the condition of the prosthesis. The HHS for 106 total hip arthroplasties with a minimum follow-up of ten years, no medical complications after operation and no evidence of radiological loosening, and the KSS for 264 total knee arthroplasties with a minimum follow-up of 12 years and no medical complications after operation or signs of radiographical loosening were evaluated. There were statistically significant drops in the functional scoring components of the joint evaluation systems despite no loosening of the prostheses or other significant medical complications. The HHS declined at an average of 0.67 points per year from between three and ten years after operation (p < 0.0001). Contributing to this were deterioration in gait and limp (p < 0.0004), the use of support aids (p < 0.0001), the distance walked (p < 0.0001) and the ability to climb stairs (p < 0.0455). The functional component of the KSS declined significantly at an average 0.88 points per year betwen the third and 12th years (p < 0.0001). There were significant declines in every component of the functional score including the distance walked (p < 0.0001), the ability to climb stairs (p < 0.0001) and the use of support aids (p < 0.0001). The knee score component of the KSS did not decline significantly (p < 0.9750). The combination of functional and pain scores within the HHS system leads to an inaccurate decline in the entire score. The decline of HHS and Knee Society functional scores in total joint arthroplasties, in the absence of implant-related problems, suggests that deterioration in the functional capacity of ageing patients is an important factor in longitudinal studies using these scoring systems.

The purpose of this study was to evaluate the results of the Thrust Plate Prosthesis as a treatment option for osteoarthritis of the hip in young patients. Of the fifty patients (63 hips) reviewed, 31 (62%) were males and 19 (38%) females. Pre-operative diagnosis included primary osteoarthritis (23), developmental dysplasia (8), avascular necrosis (7), Perthes (4), post-traumatic arthritis (3), rheumatoid arthritis (2), ankylosing spondylitis (1), psoriatic arthropathy (1) and slipped upper femoral epiphysis (1). All components were implanted uncemented with metal-on-metal articulation. The average follow-up was 4.04 years (range 12 months-8.5 years). The mean age of the patients was 42.3 years (range 21-57 years). The mean pre-operative Harris Hip Score was 41.9 (range 12-89) and at final follow-up 89.91 (range 41-100). In 25 hips with > or = 5 yr follow-up, the average HHS at final follow-up was 84.5 (range 50-100). Complications included dislocation (2), transient sciatic nerve palsy (1), discomfort from lateral strap (2), implantation of wrong femoral head (1), revision (3 = 4.76%) and implant loosening (4) (6.35%). The thrust plate prosthesis is a useful alternative in young patients with hip arthritis and the results are comparable with other uncemented hip replacements. The added advantage is preservation of the proximal femoral bone stock, which can prove useful in future revisions.

The clinical and radiographic features of 109 hybrid total hip replacements performed between 1986 and 1992 in 96 consecutive patients were retrospectively reviewed. A cementless Harris-Galante (HGP1) cup and a 32 mm monobloc straight Muller stem were used in all cases. The overall prevalence of distal femoral cortical hypertrophy (DCH) was 43.1%. Male sex, underlying diagnosis of avascular necrosis and Charnley grade A were among the factors that predisposed to the development of DCH. The prevalence of stem radiolucencies was lower in the group of patients who developed DCH compared with those without hypertrophy. The Harris Hip Score ranged between 5 and 54 preoperatively and the average HHS was more than 80 postoperatively. No association was found between DCH and thigh pain.

The purpose of this study is to describe our early experience in the development and use of a minimally invasive, anterolateral approach to the hip joint for total hip arthroplasty (THA). This approach uses a specific intraoperative protocol involving leg positioning to maximise exposure and hip joint visualisation. Between October, 2004 and December, 2004, we operated on 18 male and 29 female patients without selection and in consecutive order. The average patient age at surgery was 66 years (range 28 to 86 yrs) with an average body mass index (BMI) of 26 (range 18 36) and with a majority of patients presenting with osteoarthritis as the primary indication for surgery. The average length of the skin incision was 8 cm and the average incision-to-suture time was 45 minutes. The preoperative average Harris Hip Score was 38 and improved to 70 at 10 days postoperatively, and 92 at three and six months. Similarly, the HHS average pain component score increased from 12.6 preoperatively to 39 at 10 days postoperatively, and 40 at three and six months. An exact neutral implantation of the stem was found in 48% of the patients, between one to three degrees out of neutral in 40% and greater than four degrees of varus in 12%. The average inclination angle of the cup was measured at 44 degrees. No intraoperative or perioperative complications of any kind occurred in this series of 47 consecutive patients. From our experience, the MIS AL approach for THA with patients in the lateral position can be applied without restrictions for patient indication. Improved results can be observed when using the MIS AL approach, especially in the ear-ly postoperative phase. Since the abductors can be completely spared during the surgery, improved long-term results may be expected. Moreover and when necessary, an operative expansion is always possible without difficulties. Overall, the approach yields promising results.

We report the clinical and radiological outcome of 99 Zweymuller metal on metal total hip arthroplasties in 84 patients followed up prospectively for a mean period of 9.5 (range, 6-15) years. There were 29 (34.5%) male and 55 (65.5%) female patients with a mean age of 62.85 years (range, 50-70 years) at the time of surgery. All patients had osteoarthritis. One acetabular component and one stem were revised due to aseptic loosening. One femoral stem was revised due to a periprosthetic fracture. HHS score improved from a preoperative mean of 62.56 points (SD 8.87) to a final postoperative follow-up mean of 93.48 (SD 7.7). Cumulative success rate for both implants at 13 years, with aseptic loosening as the end point, was 97.05%, while for both implants at 13 years, with revision for any reason as the end point, it was 91.17%. Satisfactory results were observed with the use of this prosthesis.

The aim of the study is clinical assessment of modular arthroplasty Fenix and early assessment of 77 patient with femoral neck fracture treated with Fenix hemiarthroplasty. The mean age of the group was 77 years. There were 51 woman and 16 men in the group. Size of the used steam and head, the way of steam implantation, time of the operation and early complication was assessed. Operated patients were evaluated with Harris Hip Score, Larson I and Larson II score. The most common used steams were number 3 and 4, and the most common used head was number 44 with -4 mm offset. Mean operation time was 68.9 minute. The following early complication occurs: superficial wound infection treated with antibiotics--8 cases, pneumonia--8 cases, urinary tract infection--6 cases, intra operative femur shaft fracture during steam implantation, treated with plate osetosynthesis--1 cases. There were 14 cases of death in the group. 22 patients were evaluated with HHS and Larson. Mean score in HHS was 71 point, in Larson I--76 point, in Larson II--72 point. There was found that operating technique is similar like in the others hemiarthroplasty system and system is easy to use. Most of the stems were cemented. There was found that there are a high percent of death in femur neck fracture patient group during the first year after the operation and this kind of fractures handicap patient locomotion in spite of good hip joint function.

A retrospective review was conducted to evaluate the mid-term results (8.5 years follow-up) of the Versys ET stem (Zimmer, Warsaw, Indiana, USA). From 1995 to 2000, 225 total hip arthroplasties (THA) were performed using this device. All patients were evaluated clinically by the Harris Hip Score, and radiographically. The Hip Score increased from 54 preoperatively to 97 points postoperatively. The stem displayed a varus alignment between 5 degrees and 10 degrees in 17 cases without any clinical consequences (HHS 96.8). We recorded one case of septic loosening and one case of aseptic loosening. The stability of the stem was radiographically evaluated according to Engh's criteria, confirming bone ongrowth in all other cases.

To address femoral bone loss in revision total hip arthroplasty (THA) we developed a technique involving impaction allografting with intramedullary mesh moulded around the revision stem, to prevent excessive cement penetration of the allograft. The length of the revision stem was determined by the extent of femoral bone loss. Between 1986 and 1998, 32 such procedures were undertaken on 28 patients. The mean pre-operative HHS for function was 22 (range 5 to 42), improving to 41 (range 12 to 47) at final follow-up. Only 1 patient presented with aseptic loosening after revision at 147 months (12.2 years). The 12.5 year survivorship for the stem was 92.8%. The technique has provided stable and durable reconstruction, with good new bone formation visible radiologically. It is technically demanding and time consuming, but it avoids the previously published problem of massive subsidence within the bone graft.
