Femoral shaft fractures treated by Ender nails using a trochanteric approach.

We describe the use of Ender nails for the internal fixation of femoral shaft fractures by a closed technique via the greater trochanter and report the treatment of 100 patients with 106 fractures, of which 88 were reviewed 12 months or more after operation. There was primary union in 85 fractures (96.6%) and significant angulation, rotation or leg length discrepancy in eight (9%). We discuss the principles of management which we have evolved.

Rupture of the left main-stem bronchus with a polyvinylchloride double-lumen tube.

Double-lumen tubes have proved to be a useful adjunct in thoracic surgery. Their use has become quite commonplace, particularly since the introduction of the softer polyvinylchloride (PVC) tubes, which are technically easier to use and may carry less risk for serious complications. Any such tube, however, can cause life-threatening complications. We present a case with such a complication related to the use of a PVC double-lumen tube and make recommendations regarding the use of these tubes to minimize the risk of serious intraoperative complications.

Interrelationships of physician performances: technical quality and utilization and implications for quality and utilization controls.

The study determined the intrarelationships and interrelationships of two sets of physician performance measures: technical quality and utilization of medical resources. The performance measures were based on 2,431 episodes in 15 diagnostic categories involving 454 physicians. A series of correlations were used to determine these relationships. The technical performance of physicians for prehospitalization, hospitalization, and posthospitalization care were found to be positively related (r=.38). The interrelationships between efficient utilization and technical quality were also positive (r=.22). There appears to be some homogeneity in the performance in the areas of technical quality and utilization patterns, but this is not strong enough to allow substitution one for another. It is therefore recommended that efforts to control or measure quality of care and utilization patterns need to be directed to each aspect of physician performances.
