BACKGROUND
This study evaluated the clinical results of a new implant in the internal fixation of undisplaced femoral neck fractures.
METHOD
Irrespective of their age, 149 patients with undisplaced (Garden I and II) femoral neck fractures were included in a prospective multicentre clinical cohort study and were treated by internal fixation by means of the Dynamic Locking Blade Plate (DLBP). The mean age was 69 years and the follow-up at least one year.
RESULTS
The DLBP fixation resulted in 6 out of 149 failures caused by AVN (2x), non-union (2x), loss of fixation (3x) or combination of these.
CONCLUSION
The fixation of undisplaced femoral neck fractures by the DLBP resulted in a low failure rate of 4 %.
背景
本研究评估了一种新型植入物用于无移位股骨颈骨折内固定的临床效果。
方法
149例无移位（Garden I型和II型）股骨颈骨折患者，无论年龄大小，均纳入一项前瞻性多中心临床队列研究，并采用动力锁定刀片钢板（DLBP）进行内固定治疗。平均年龄为69岁，随访至少一年。
结果
在149例患者中，有6例因股骨头缺血性坏死（2例）、骨不连（2例）、内固定失败（3例）或这些情况的组合而导致治疗失败。
结论
采用DLBP对无移位股骨颈骨折进行固定，失败率较低，为4%。
