Despite the general success of the sliding hip screw for stabilization of intertrochanteric fractures, there is dissatisfaction with the resultant deformity associated with its use, particularly in unstable fracture patterns. These concerns have resulted in increasing use of intramedullary devices for treatment of peritrochanteric fractures. Use of an intramedullary device for peritrochanteric fracture stabilization limits the amount of lag screw sliding and resultant limb deformity, particularly shortening, since the fracture can settle only until the proximal fragment abuts against the nail. This article describes some of the advances in intramedullary nails used to stabilize peritrochanteric fractures.
尽管滑动髋螺钉在稳定转子间骨折方面总体取得了成功,但人们对其使用所导致的畸形仍不满意,尤其是在不稳定骨折类型中。这些担忧导致髓内装置在治疗转子周围骨折中的使用越来越多。使用髓内装置稳定转子周围骨折可限制拉力螺钉的滑动量以及由此导致的肢体畸形,特别是缩短畸形,因为骨折只能在近端骨折块抵住髓内钉时才会复位。本文介绍了用于稳定转子周围骨折的髓内钉的一些进展。
