Case ReportsGiant cell tumor of rib--rare location on the anterior aspect.
Giant cell tumor rarely occurs in ribs, where it presents posteriorly. We present a report of a giant cell tumor of bone occurring anteriorly in the rib with a review of the literature.

The influence of obesity on perioperative morbidity and mortality in revision total hip arthroplasty.
The significance of obesity as a risk factor for postoperative complications was determined in a consecutive series of 229 cases of revision total hip replacement. The body mass index (BMI) was used as an objective measure to classify the patients. ⋯ The results of our study demonstrate a clear association between obesity and operative time, whereas no statistically significant relationships were observed between obesity and the other parameters. We conclude that obesity does not have any significant influence on perioperative morbidity and mortality but is clearly related to operation time and, therefore, to higher costs per operation.

Early recovery of isometric shoulder muscle strength after open acromioplasty in stage II impingement syndrome.
The recovery of shoulder muscle strength after open acromioplasty was evaluated in 48 patients (27 male, 21 female, mean age 44.3 years) who had undergone open acromioplasty because of stage II impingement syndrome. The isometric strengths of flexion, abduction and external rotation were measured before the operation and at 3, 6 and 12 months postoperatively. The mean preoperative flexion strength of the involved shoulder was 72.6% of that of the uninvolved shoulder, and this increased to 77.1% by 3 months post operation, to 88.3% at 6 and to 88.3% at 12 months. ⋯ These recoveries were markedly improved when the cases with poor subjective results at 1 year were not considered. The low preoperative strengths were more pronounced in women than in men, but recovery was better in women. It is concluded that shoulder muscle strengths recover to near normal in 1 year after open acromioplasty.

Case ReportsFemoral nerve palsy in hip replacement due to pelvic cement extrusion.
We report a case in which cement protrusion into the pelvis led to a major complication. During reaming and preparation of the anterosuperior acetabulum, a bony defect resulted which made fixation of an uncemented cup impossible, and a cemented polyethylene cup was used instead. ⋯ Postoperative X-rays and CTs showed that a huge mass of bone cement protruded into the pelvis in close proximity to the iliac vessels and the femoral nerve. This probably led to nerve damage during the cement's polymerisation process due to the heat.

Magnetic resonance imaging as a screening procedure to avoid arthroscopy for meniscal tears.
The objective of this study was to evaluate the role of magnetic resonance imaging (MRI) as a screening procedure before arthroscopy of meniscal tears. Forty-one knees in 40 patients underwent MRI and arthroscopy. ⋯ The overall accuracy for MRI of the medial and lateral menisci combined was 84%. On the basis of the high predictive value of negative MRI, we conclude that MRI is useful to exclude patients from unnecessary arthroscopy.
