Proximal femoral fractures remain the most common reason for admission to hospital following orthopaedic injury, with an annual cost of £1.7 billion to the National Health Service and social care services. Fragility fractures of the hip in the elderly are a substantial cause of mortality and morbidity. Revision surgery for any cause carries a higher morbidity, mortality, healthcare- and social economic burden. Which patients suffer failed surgery and the reasons for failure have not been established. The aim of this study was to determine which patients are at risk of failed proximal femoral fracture surgery, the mechanism and cause fo failed surgery and modifiable patient factors associated with failure of hip fracture surgery.
From prospectively collected data of 795 consecutive proximal femoral fractures admitted between July 2007 and July 2008, all peri-operative and post-operative complications were identified.
55 (6.9%) patients were found to have developed a surgical complication requiring further intervention. Risk factors included younger age (p=0.01), smoking (p=0.01) and cannulated screw fixation (p<0.01). Cannulated screw fixation was associated with a 30.9% complication rate. Mechanical cause was the most common reason for cannulated screw failure. Hip hemiarthroplasty most commonly failed by infective causes. Inter-trochanteric and subtrochanteric fracture fixation had very low failure rates. Surgical complication was not found to be associated with an increased mortality but a post-operative medical complication (21.8%) was associated with higher rate of mortality at 4-years (78.5%) and shorter time to mortality. (Median time 0.16 years (95% CI 0.00–0.33).
