Self-bearing, uncemented, ceramic total hip replacement arthroplasty.

The results for young patients in three diagnostic groups--osteoarthritis, posttraumatic arthritis, and osteonecrosis--show clearly that the uncemented procedure requires longer a recovery time than the cemented procedure. A more aggressive physical therapy program has resulted in an earlier return to function, as shown in these graphs. In conclusion, our experience with this operative procedure includes excellent patient acceptance, a failure rate comparable to that in Europe, a longer period of recovery than that for cemented arthroplasty, excellent results in revision of failed cemented arthroplasty, and an encouraging facility in the difficult case.

Orthopaedic aspects of the VATER association.

The cases of twenty-eight patients with the VATER association, which consists of various combinations of vertebral anomalies, anal atresia, tracheoesophageal fistula with esophageal atresia, radial dysplasia, and renal anomalies, were reviewed. Associated anomalies included deformities of the ribs and lower limbs, a two-artery umbilical cord, a congenital heart defect, and auricular deformities. Three children died in the first two years of life. Of the remaining twenty-five patients, twelve have required a total of seventeen orthopaedic procedures for the treatment of congenital scoliosis or deformity of the upper or lower extremities.

Controlled hypotensive anesthesia during spinal surgery. A retrospective study.

A retrospective study has been made of 264 posterior spinal fusions performed between 1972 and 1978 at the Good Samaritan Hospital in Cincinnati. Two hundred ten of the procedures were performed under hypotensive anesthesia. Blood loss and total blood replacement were related to the mean arterial pressure (MAP) during surgery. A 42% reduction in total intraoperative loss and a 28%reduction in total blood requirements were demonstrated. The results were significantly different when patient age was considered in adults maintained below 80 mmHg MAP, blood loss was decreased by 33%, but the total blood requirement was decreased by only 6%; in children under 18 years of age maintained below 90 mmHg MAP, the blood loss was decreased by 49% and the blood requirement by 42%.
