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.

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.

ReviewLocking screw-plate fixation of cervical spine fractures with and without ancillary posterior plating.
Forty consecutive patients with 19 fractures and 21 fracture-dislocations in the lower cervical spine were treated prospectively with open reduction and interbody fusion, using the AO titanium locking screw-plate system. There were 30 men and 10 women with a mean age of 36 years (range 16-90 years). Eight were admitted tetraplegic, 12 tetraparetic, and 6 had nerve root injuries. ⋯ Six screws transgressed facet joints below the fusion. Ten posterior fusions extended to adjacent mobile segments by exuberant bony overgrowth. Ancillary posterior plating significantly reduced the range of neck mobility and also caused significantly more pain than anterior plate fixation alone.

ReviewBlood loss in total hip replacement. A retrospective study.
Two hundred and twelve total hip replacements performed in one clinic over 1 year were reviewed. The mean operative time was 89 min and mean total blood loss 1090 ml. Homologous blood was administered to 74% of the patients. ⋯ Despite a mean of only 12 total hip replacements per surgeon, both operative time and blood loss were small compared to what was found in other studies. The use of a posterior approach is believed to contribute to a shorter operative time as well as to moderate blood loss. Intraoperative blood loss was less under epidural than under general anaesthesia, but in contrast to others we found higher postoperative blood loss after epidural anaesthesia.

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.
