We compared, after a 10-year-minimum follow-up, the outcome of 50 cemented all-polyethylene Charnley acetabular sockets with that of 51 cementless metal-backed sockets in 2 comparable cohorts of young patients. Although the revision rate for the cemented and cementless group was 28% and 35%, respectively, the revision rate for aseptic loosening was 28% for(More)
We evaluated the effect of the inclination angle, position, and containment of 53 cementless cups inserted in patients with congenital hip disease (CHD), after a minimum of 10 years of follow-up. The polyethylene wear rate was significantly greater when the cup was placed in more than 45° inclination (P=.045) or if the cup was placed lateral to the teardrop(More)
The purpose of the present study was to evaluate the long-term outcome of the unrevised part in one-component total hip arthroplasty revision (index operation). Forty-four patients (46 hips) with a mean age of 58years at the time of the index operation were included. At the final follow-up, 4 of the 19 (21%) unrevised acetabular components and 6 of the 27(More)
We report the updated results at a minimum of fifteen years after eighty-four consecutive total hip arthroplasties performed in sixty-seven female patients with high dislocation of the hip. Sixty-four arthroplasties were performed in forty-nine patients, between 1976 and 1994, with Charnley low-friction acetabular and femoral components inserted with(More)
BACKGROUND We previously reported the outcomes at a minimum of twelve years after eighty-four Charnley low-friction arthroplasties performed in patients with osteoarthritis who were less than fifty-six years old at the time of the surgery. We now update the results of that cohort at a minimum of twenty-two years postoperatively. METHODS Eighty-four hips(More)
Previous studies have shown that anatomical abnormalities of the femur in dislocated hips require the application of special CDH prosthesis for the reconstruction of the proximal femur in total hip arthroplasty (THA). We have retrospectively examined the clinical records and radiographs of 50 patients (67 hips) with low and high dislocations treated with(More)
In this paper we described the development of both the hardware and the algorithms for a novel laser vision system suitable for measuring distances from both solid and mesh-like targets in underwater environments. The system was developed as a part of the AQUABOT project that developed an underwater robotic system for autonomous inspection of offshore(More)
