METHODS: Retrospective and comparative study of 53 patients with femoral neck fracture, operated between 2015 and 2022 with fixation with three cannulated screws, 22 with a triangle configuration (triangle group) and 31 in an inverted triangle (inverted triangle group). Functionality was evaluated using the modified Merlé d\'Aubigné scale, walking ability using the Koval scale, as well as postoperative complications.
RESULTS: On the Merlé d\'Aubigné scale, the mean score was 16.7 in the triangle group and 16.1 in the inverted triangle group (P=.259). On the Koval scale, a significant decrease was observed, going from 1.6 preoperative mean to 2.2 after surgery (P=.000), finding no differences between groups. There were six postoperative complications in the triangle group and three in the inverted triangle group (P=.140).
CONCLUSIONS: The configuration of the screws in the femoral neck, both in the form of a triangle and an inverted triangle, did not influence the functional or mechanical outcomes of the patients with a femoral neck fracture fixed with three cannulated screws.
结果:在Merled\'Aubigne量表上,三角形组的平均得分为16.7分,倒三角形组的平均得分为16.1分(p=0.259).在Koval尺度上,观察到显著下降,从术前平均1.6到术后2.2(p=0.000),发现组间没有差异。三角形组术后并发症6例,倒三角形组术后并发症3例(p=0.140)。
结论:股骨颈螺钉的配置,以三角形和倒三角形的形式,对使用三颗空心螺钉固定的股骨颈骨折患者的功能或机械结局没有影响。
