Fixed angle devices versus multiple cancellous screws: what does the evidence tell us?

Complications, including nonunion and avascular necrosis, are relatively common after internal fixation of a femoral neck fracture. Young patients are particularly impacted by these complications as salvage options often result in a suboptimal functional result. The quality of reduction appears to be of primary importance; however, it is unknown whether the choice of internal fixation affects the incidence of complications. In this article, we present the rationale and evidence for available internal fixation options. Current evidence is insufficient to recommend an optimal method of internal fixation, and this review demonstrates the need for high-quality randomised, controlled trials to study this problem.
