ReviewTen-year results of tibial osteotomy for medial gonarthrosis. The influence of overcorrection.
The results in relation to the correction achieved 1 year after surgery of a series of tibial osteotomies in 50 patients (52 knees) are presented with a total observation time of 10 years. Mean age at the time of osteotomy was 56 years. ⋯ One out of 34 overcorrected knees recurred in varus. Five knees were revised by knee arthroplasty or reosteotomy one of which was overcorrected.

Review Case ReportsNonunion of a comminuted intra-articular wrist fracture after external fixation. A case report and review of the literature.
Nonunion is a very rare complication of a comminuted intra-articular wrist fracture treated by external fixation. The authors describe the likely reasons and the after-care, in order to avoid this complication.

ReviewSystemic effects of implanted prostheses made of cobalt-chromium alloys.
Systemic effects of Co-Cr alloy/polyethylene hip joint prostheses were investigated using instrumental neutron activation to determine the concentrations of up to 16 elements. First, in a prospective study whole blood and serum taken from 10 patients from 1 day before to 90 days after implantation were analyzed. Secondly, in a retrospective study whole blood and serum from 23 patients who had had prostheses in place for up to 18 years were analyzed. ⋯ The analyses of tissues from the vicinity of the implants in the two deceased implant patients showed strong local effects of Co, Cr, Zr, and Hf, the latter two elements originating from the X-ray contrast media in the bone cement. The analyses of organs revealed significant Co and Cr enrichment in several tissues and organs. Consequently, it can be seen that implant corrosion is not an occurrence of merely local significance, but one that affects the trace element status of the entire organism.

Review Case ReportsTraumatic dislocation of the hip in young children.
Traumatic dislocation of the hip joint is an uncommon injury in children. The present report on this traumatic emergency is based on the authors' own observations of three cases and a review of the literature. ⋯ The crucial therapeutic intervention to avoid this serious complication seems to be immediate, usually closed, reduction under general anaesthesia. A management protocol is presented.

The blood levels of the active metabolites of vitamin D3 25-hydroxycholecalciferol [25(OH)D3]. 1,25-dihydroxycholecalciferol [1,25(OH)2D3], and 24,25-dihydroxycholecalciferol [24,25(OH)2D3] were determined in 27 patients suffering from arthrosis of the knee, including 4 patients with non-insulin-dependent diabetes mellitus. The blood level of 24,25-dihydroxycholecalciferol was found to be significantly lower in patients with gonarthrosis than in patients with coxarthrosis. With the exclusion of the diabetic patients, the mean value for this metabolite was lower than in the coxarthrosis group, but the difference was not significant statistically.
