  • Title: Technical pitfalls in the use of the sliding hip screw for fixation of intertrochanteric hip fractures.
    Author: Rokito AS, Koval KJ, Zuckerman JD.
    Journal: Contemp Orthop; 1993 Apr; 26(4):349-56. PubMed ID: 10148465.
    Abstract:
    Two hundred fifty consecutive intertrochanteric fractures treated with a sliding hip screw (SHS) over a three year period were reviewed and specific types of technical pitfalls identified. Most pitfalls were technique dependent and potentially preventable with proper attention to the principles of fracture reduction and insertion of the device. Pitfalls encountered with the use of the SHS occurred as a result of either poor fracture reduction or implant insertion. Problems related to fracture reduction included poor radiographic visualization, posterior sag, varus angulation, and internal rotation of the femoral shaft in relation to the femoral neck. Potential pitfalls encountered during SHS insertion included superior guide wire placement, guide wire breakage or penetration into the hip joint or pelvis, loss of reduction during lag screw insertion, improper screw-barrel relationship, and improper plate application. Finally, the SHS may not be the implant of choice for all extracapsular hip fractures (i.e., the reverse obliquity fracture). This paper identifies the various pitfalls that may occur with the use of the SHS for the fixation of intertrochanteric hip fractures. Illustrative cases are provided and guidelines for avoiding these surgical pitfalls suggested.
