A case of a patient with traumatic, simultaneous right posterior and left anterior hip dislocations without associated fractures is reported. Simultaneous asymmetric bilateral hip dislocation is very rare. The mechanism of this injury is discussed.

We report the clinical and radiograph outcome of 77 Furlong hydroxyapatite fully coated femoral prosthesis in 71 patients undergoing primary total hip replacement, with mean follow-up of 65 months (range 48-82 months). The patients' average age at surgery was 55 years. The clinical results, as determined by Harris hip score, were excellent or good for 84% of the hips. Thigh pain which was not disturbing was present in 9% of the hips. No femoral component had been revised for aseptic loosening, and none were considered loose radiographically at the time of final follow-up evaluation. Serial radiographs revealed an excellent quality of bone around the prostheses, with positive evidence of bone ingrowth and no signs of impending failure.

This report describes a patient with primary hyperparathyroidism who became spontaneously normocalcaemic preoperatively. This was due to infarction in a parathyroid adenoma. Plasma parathormone (PTH) levels were monitored pre- and postoperatively.
