Intertrochanteric fracture is the most frequent type of fracture in the proximal femur and the compressive hip screw is one of the most popular methods of treatment. The reduction criteria for this type of fracture are ill-defined. The purpose of this study was to validate 3 reduction criteria: displacement, alignment in the anteroposterior and in the lateral plane. We reviewed a cohort of 430 intertrochanteric fractures treated with a compression hip screw. The type of fracture, quality of reduction and technical complications were noted. We observed a relationship between accuracy of reduction and the incidence of complications, even among fractures of the same severity. A displacement bigger than 4mm and failure to accomplish correct alignment (a neck-shaft angle over 125 masculine and less than 20 degrees angulation on the lateral view) was considered a poor reduction and was associated with more complications.
转子间骨折是股骨近端最常见的骨折类型，加压髋螺钉是最常用的治疗方法之一。此类骨折的复位标准尚不明确。本研究的目的是验证3种复位标准：移位、前后位和侧位对线。我们回顾了一组430例采用加压髋螺钉治疗的转子间骨折。记录骨折类型、复位质量和技术并发症。我们观察到复位的准确性与并发症的发生率之间存在关联，即使在相同严重程度的骨折中也是如此。移位大于4mm以及未能实现正确对线（颈干角大于125°且侧位X线片上成角小于20°）被认为是复位不佳，并与更多并发症相关。
