[Treatment of trochanteric fractures with the gamma nail].
The osteosynthesis of trochanteric fractures requires a minimal invasive technique to guarantee fully weight bearing and early rehabilitation in elderly patients. In this retrospective study we want to prove if the gamma nail meets all requirements and if the results improved after initiation of the new instrumentarium and standardization of the operative technique. From January 1992 until April 2000 we treated 387 patients with a gamma nail. The average age was 79.4 years. We used the new instrumentarium suitable for radiography since June 1996, the operative technique was standardized since the same time. The evaluation occurred on the basis of clinical and radiological findings included analysis of complications. We've seen intraoperative problems in 29% before June 1996, this rate could be reduced to 9%. General postoperative complications presented in equal frequency. After improvement of the technique dislocations of the neck screw and relevant sinking of the fractures were more rarely. The rate of reoperations after complications of the implant was 8% in both groups. In consideration of technical standards the postoperative full weight bearing and early mobilisation is possible even in old patients.
