Surgical management of hip fractures: an evidence-based review of the literature. I: femoral neck fractures

During the past 10 years, there has been a worldwide effort in all medical fields to base clinical health care decisions on available evidence as described by thorough reviews of the literature. Hip fractures pose a significant health care problem worldwide, with an annual incidence of approximately 1.7 million. Globally, the mean age of the population is increasing, and the number of hip fractures is expected to triple in the next 50 years. One-year mortality rates currently range from 14% to 36%, and care for these patients represents a major global economic burden. Surgical options for the management of femoral neck fractures are closely linked to individual patient factors and to the location and degree of fracture displacement. Nonsurgical management of intracapsular hip fractures is limited. Based on a critical, evidence-based review of the current literature, we have found minimal differences between implants used for internal fixation of displaced fractures. Cemented, unipolar hemiarthroplasty remains a good option with reasonable results. In the appropriate patient population, outcomes following total hip arthroplasty are favorable and appear to be superior to those of internal fixation.
