Technologies for Young Femoral Neck Fracture Fixation

Abstract

Fixation of young femoral neck fractures represents a challenge in the field of orthopaedic trauma surgery. Conventional methods, including cannulated screw and sliding hip screw constructs, have been studied and found to have similar results with regards to patient outcomes, which has made choosing an optimum fixation strategy difficult. In all of these cases, quality of reduction has been shown to be the most important factor when it comes to creating a favorable environment for fracture healing. Some of these patients, however, continue to have negative sequelae including nonunion, avascular necrosis, femoral head collapse, and poor hip function as a result. In this article, we review the 2 most commonly used constructs and present 2 novel fixation constructs for the fixation of femoral neck fractures in physiologically young patients, including the Smith & Nephew Conquest system and the Aesculap Targon system. We outline techniques for usage of these systems and proposed advantages to these systems compared with conventional fixation methods. We also discuss the results of previously published studies regarding conventional fixation methods and compare with some limited studies that have been published on these newer technologies.
