“…Nonetheless, since FDA approval was granted, a circumferential treatment by corundumisation has been used to 'seal' the proximal femur and shield the implant from wear debris. 30,31 The current technique also preserves the lateral neck of the femur, thus reducing the access of wear debris to the proximal femur. While the generation of wear particles remains an unsolved problem, the present design has shown that preservation of bone at the initial operation is possible and subsequent revisions may be achieved with conventional designs of primary implant.…”

Between 1985 and 1993, 146 patients (162 hips) had total hip replacement (THR) using a conservative uncemented femoral component. The mean age of the patients was 50.8 years and the mean follow-up was 6.2 years (2 to 13). One patient was lost to follow-up, one died within two years of surgery and one had a revision procedure after a fracture sustained in a road-traffic accident.For the remaining 159, Kaplan-Meier survival analysis was calculated for the incidence of revision because of mechanical loosening or osteolysis. Survival without mechanical loosening at both five and ten years was 98.2%. Survival without osteolysis was 99% at five and 91% at ten years. The Harris hip score improved from a mean of 66.3 before to 90.4 at follow-up. Of particular note is the lack of thigh pain in this group. Radiological analysis showed that 139 stems (88%) had no measurable subsidence, 8 (5%) had less than 2 mm and 12 (7%) had more than 2 mm. Two of the eight and one of the 12 were revised for mechanical loosening. Nine hips were revised for late loosening associated with osteolysis. No reaming of the femoral canal was associated with statistically significant less blood loss compared with a comparable control group of uncemented implants (p < 0.0001).Our study suggests that using a conservative femoral implant does not protect against wear debris but the reliable mechanical stability (98.2%) makes this an attractive design of implant particularly for young patients.

“…Clinical follow-up studies of non-cemented implants failed to prove superiority over cement-fixation until the late-nineties. The reported mechanical loosening-rates (revised and non-revised) for short-and mid-term follow-up are between 6 and 52% for the majority of studies [1,3,6,7,[14][15][16][17]21,25,26]. Successful short-term results have been reported for a few stem designs, i.e.…”

A series of total hip replacements was performed using a proximally porous coated, tapered femoral stem system. At a mean follow-up of 8.1 (5-13) years, 80 out of 107 hips were available for clinical and radiological examination. The mean age at the index procedure was 58.6 years. The mean Harris Hip Score at final follow-up was 91.7. Radiological ingrowth was observed in 77 femoral stems, 2 stems were fibrous stable and 1 stem was loose.Résumé Nous avons realisé une étude rétrospective comprenant 80/107 prothèses totale de la hanche en utilisant une tige fémorale avec fixation proximale noncimentée. L`age moyen des patients lors de l`intervention était de 58.6 ans. La durée moyenne d`observation post-opératoire était de 8.1 ans. Le score de Harris lors du dernier examen clinique était de 91.7. Une incorporation radiologique idéale était observée dans 77 tiges, 2 tiges étaient stables et 1 tige était descellée.

“…Für zementierte Prothesen liegen z. T. ausgezeichnete Nachuntersuchungsergebnisse vor [10,20,28,38]. Bei zementfreien Endoprothesen fehlen trotz beachtenswerter publikatorischer Aktivität zahlreicher Arbeitsgruppen Langzeitergebnisse jenseits der 10-Jahres-Frist fast noch vollständig [7,8,13,32,33,42].Andererseits ist besonders in Zeiten zunehmend wichtiger werdender wirtschaftlicher Überlegung eine streng rationale Implantatwahl auf der Basis prospektiver Studien notwendig [4,27].…”

A higher-than-average rate of aseptic loosening has been postulated to be associated with the combination of a titanium stem and bone cement. In this prospective follow-up study we therefore investigated our first consecutive series of 250 implantations of a cemented femoral shaft prosthesis made of titanium alloy (BiCONTACT((R)), Aesculap, Tuttlingen, Germany). Average time of follow-up evaluation was 9.7 years (range 8.7-10.3 years). At follow-up, mean patient age was 81 years; 89 patients with 93 hips have deceased and two could not be located. Follow-up rate was 98.7% for the patients still alive at time of follow-up evaluation. Five patients have been revised, two for infection and one for aseptic loosening of a varus-malaligned stem; two radiologically well-fixed stems had been revised during acetabular revision. Survival estimate showed a calculated cumulative survival rate of 97.5% after 11 years [confidence limits: 99.0% (upper) and 94.1% (lower)]. The average Harris hip score at time of follow-up was 82.25 points.Radiologically, signs of loosening could be detected in 3 stems: in one case varus malalignement deteriorated with time and in 2 cases osteolyses developed together with significant polyethylene wear. All 3 patients experienced only mild pain and revision had not been indicated so far. In conclusion, the long-term follow-up results with this cemented titanium femoral component are encouraging and are comparable to other successful cemented femoral components in primary total hip arthroplasty. No increased risk for aseptical loosening was associated to the combination of titanium and cement in this specific stem. Design parameters seem to play an important role in the development of aseptic loosening in cemented titanium stems.
