The aim of this study was to clinically evaluate two generations of intramedullary gamma-nail used in the treatment of 31-A femur fractures.
In two consecutive series, 117 trochanteric gamma nails (TGN) and 100 Gamma3 nails (G3N) were implanted for the treatment of inter- and subtrochanteric fractures between 2009 and 2011. Clinical and radiological follow-up examinations were assessed. An analysis of surgical time, hemoglobin drop and complications were performed.
Average surgical time, fluoroscopy time, haemoglobin drop and length-of-stay (LOS) were similar in both groups. No significant differences were found in surgery-related complications like wound hematomas (=0,59), abscesses (=0,38), wound infections (=0,69) and Cut-outs (=0,69) between the two groups. The cumulative surgery-related complication rate was higher in the TGN group compared to the G3N group (13,68% 8%) but this did not reach statistical significance (=0,2).
Our findings suggest that both TGN and G3N allow adequate treatment of trochanteric fractures with an acceptable complication rate.
本研究旨在对用于治疗31 - A型股骨骨折的两代髓内伽马钉进行临床评估。
在两个连续系列中，于2009年至2011年植入117枚股骨粗隆间伽马钉（TGN）和100枚Gamma3钉（G3N）用于治疗粗隆间和粗隆下骨折。对临床和放射学随访检查进行评估。分析手术时间、血红蛋白下降情况及并发症。
两组的平均手术时间、透视时间、血红蛋白下降情况及住院时间相似。两组在手术相关并发症如伤口血肿（=0.59）、脓肿（=0.38）、伤口感染（=0.69）和内固定物穿出（=0.69）方面未发现显著差异。TGN组的累积手术相关并发症发生率高于G3N组（13.68%对8%），但未达到统计学显著性（=0.2）。
我们的研究结果表明，TGN和G3N均可对粗隆间骨折进行充分治疗，并发症发生率可接受。
