[CAN HIP FRACTURE PATTERN OR TYPE OF SURGERY PREDICT ONE-YEAR MORTALITY OR MOBILITY?]

Several demographic and medical factors have an established effect on mortality and function after hip fractures, however varying fracture characteristics and surgical factors have been less thoroughly investigated. The study assessed the impact of specific fracture patterns on mortality and mobility one year post hip fracture. Other surgical factors including the type of intervention, major complications and sequential fractures were assessed as well.

An institutional hip fracture registry was reviewed. Mobility status scores were calculated one year post-operatively.

Thirty days mortality was 4.6% and one year mortality was 19.9%. There was no significant effect of fracture type on mortality. However, patients receiving hemiarthroplasty had a significantly higher mortality (28.1%) than other patients receiving internal fixation (18.6%) or total hip arthroplasty (4%). An increased mobility status after intra-capsular fractures over extracapsular fractures was demonstrated. Patients receiving total hip arthroplasty had significantly better mobility at one year than patients with fracture fixation or hemiarthroplasty. Major complications and sequential fractures had no significant effect on outcome.

Critical factors that influence decision making for orthopedic surgeons are revealed to have a lesser effect on the patient's ultimate outcome.
