Background: Practice variation may indicate a lack of clear evidence to guide treatment. This study aims to quantify practice variation for common orthopaedic fractures, and to explore possible predictors of the variation., Materials and Methods: A nationwide electronic survey of Australian orthopaedic surgeons was performed. Five common fractures (ankle, scaphoid, distal radius, neck of humerus, and clavicle) were presented. Data on management preferences and surgeon background were gathered. Potential predictors of operative (vs. non-operative) treatment were explored., Results: 358 of 760 (47%) surgeons responded. For the ankle, undisplaced scaphoid, distal radius, neck of humerus and clavicle fractures, operative treatment was chosen in 40%, 44%, 77%, 26% and 38%, respectively. Operative treatment was significantly more likely to be chosen by more junior surgeons, and by surgeons specialising in the affected area (i.e., shoulder surgeons for clavicle and neck of humerus fractures, and hand surgeons for scaphoid and distal radius fractures)., Conclusions: Variations exist in the management of common fractures. Variation may represent legitimate improvisation for varying clinical scenarios, but it may reflect clinician bias, which in turn, may contribute to varying standards of care for the management of common conditions., (Copyright © 2010 Elsevier Ltd.
