Abstract：
OBJECTIVE: Synthesis with cannulated screws is one of the accepted methods in femoral neck fractures, although its optimal configuration is a subject in continuous debate. The main objective was to compare the results of the patient with a femoral neck fracture fixed with three screws in triangle and inverted triangle configuration in the frontal plane.
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.

摘要：
目的：空心螺钉合成是股骨颈骨折的公认方法之一，尽管它的最佳配置是一个不断争论的话题。主要目的是比较患者在额平面上用三角形和倒三角形配置的三个螺钉固定股骨颈骨折的结果。
方法：对53例股骨颈骨折患者进行回顾性对比研究,在2015年至2022年之间使用三个空心螺钉进行固定，22具有三角形配置(三角形组)和31在倒三角形(倒三角形组)中。使用改良的Merléd\'Aubigné量表评估功能，使用Koval量表的行走能力，以及术后并发症。
结果：在Merléd\'Aubigné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=.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=.000)，发现组间没有差异。三角组术后并发症6例,倒三角组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。
