Lung volume reduction (LVR) is a new surgical approach designed to relieve shortness of breath and to improve exercise tolerance in patients with severe lung emphysema. Selection of patients for LVR is based on history, clinical investigation, chest X-ray studies, CT scan, lung perfusion scan, lung function testing, and blood gas analysis. Selection criteria are severe emphysema (FEV1 20-35% pred., TLC > 120% pred., RV > 250% pred.), dyspnea despite optimized medical therapy, abstinence from smoking, acceptable nutritional status and rehabilitation potential. ⋯ Three cases of a delayed pneumothorax were observed. Early hospital mortality (< 30 days) was 1.7% and 90 days mortality 3.4%. Few follow-up data are available beyond 1 year, and the long-term benefit of LVR surgery therefore remains to be defined.

Pelvic floor hernias are rare. Three different types can be distinguished; these are, in order of decreasing frequency: obturator, perineal and sciatic hernias. We report a rare case of a perineal hernia with an intra- and extraperitoneal part. Furthermore a two-stage surgical approach (first transabdominal, then posterior) is presented.

Posterior dislocation fracture of the shoulder is a rare injury that often occurs in association with a grand mal seizure. Our aim with this paper is to emphasize diagnosis and therapy. In the past 5 years seven patients with nine posterior dislocation fractures were treated operatively. ⋯ Six open reductions and stabilizations with screws were performed, and three times we fixed the subscapular tendon in the reversed Hill-Sachs lesion with anchor sutures. Patients after grand mal seizures may have a posterior shoulder dislocation, and clinical and radiological examination should be emphasized. In locked posterior dislocation we favour early open reduction, fixation of the subscapular tendon with anchor sutures in the reversed Hill-Sachs lesion and stabilization of the lesser tuberosity with screws.
