The aim of this study was to evaluate the short-term radiological and functional outcome of surgical treatment for symptomatic, low-grade, adult isthmic spondylolisthesis. Twelve patients underwent a monosegmental fusion for symptomatic spondylolisthesis. Posterior reduction with pedicle screw instrumentation was followed by second-stage anterior interbody(More)
Radiographic assessment of lumbar interbody fusion is difficult, especially in the presence of cages and metal artifacts. The purpose of this study is to assess whether impacted bone chips in intervertebral lumbar cages show a tendency toward increased attenuation on postoperative computed tomography (CT) scans as a sign of ongoing revascularization and(More)
Total hip arthroplasty has been a very succesful orthopaedic procedure. The optimal fixation method of the acetabular component however, has not yet been defined. We performed a systematic review using the Medline and Embase databases to find evidence for the superiority of cemented or cementless acetabular components on short- and long-term clinical and(More)
BACKGROUND In this prospective randomized study we tested the hypothesis that use of more cyclo-oxygenase 2 (COX 2)-selective non-steroidal anti-inflammatory drugs (NSAIDs) can reduce perioperative blood loss compared with non-selective NSAIDs. METHODS Data from 200 patients who underwent total hip replacement were studied. Two NSAIDs were compared:(More)
The goal of all therapies for Perthes' disease is to achieve an optimal shape of the acetabulum and an optimal coverage of the femoral head. Thirty patients who were included in this follow-up study (mean follow-up 12 years) underwent a shelf acetabuloplasty for Catterall group III or IV. The mean IOWA hip score at follow-up was 96 (max. 100 points, range(More)
The goal of this study was to evaluate the short-term effects of intradiscal electrothermal treatment (IDET) for chronic discogenic low back pain. Twenty consecutive patients with symptomatic degenerative discs were treated with IDET and evaluated preoperatively, and 3 and 6 months postoperatively. Pain was measured with a 100-mm visual analog scale (VAS)(More)
We report the updated results for a previously evaluated surgical treatment for adult low-grade isthmic spondylolisthesis. In 12 patients a decompressive laminectomy was performed followed by a circumferential fusion using posterior pedicle screw instrumented reduction and staged anterior cage-assisted interbody fusion. Average time to follow-up was 5.6(More)
BACKGROUND CONTEXT The use of stand-alone cervical interbody cages in anterior cervical discectomy with fusion (ACDF) has become popular, but high subsidence rates have been reported in the literature. PURPOSE The authors present short-term radiological results of a titanium box cage with regard to fusion and subsidence. Reliable fusion and lack of(More)
In 1986, 242 M. E. Muller (MEM) cemented, straight-stem total hip arthroplasty prostheses were implanted in 229 patients; 15 hips (13 patients) were lost to follow-up. Of the remaining 227 implants, 180 were placed in women, and 47 were placed in men (each with mean age, 71 +/- 7.7 years). After 10 years, 66 patients had died, and 152 implants were still in(More)
The authors have conducted a prospective cohort study of the efficacy of a 7 days administration of Indomethacin (n = 89) versus Meloxicam (n = 92), in the prophylaxis of heterotopic ossification (HO) in primary total hip arthroplasty. To assess the interobserver variability of the Brooker classification, all radiographs were evaluated by three(More)
