Check radiography after fixation of hip fractures: is it necessary?

Abstract

Technological advances in radiography in the form of image intensification has not only made internal fixation of femoral neck fracture much easier but these high resolution films can be saved as hard copies and can also be reversed into 'positives' at a later date. However, requesting routine post-operative check radiographs for these fractures are still a common practice. A retrospective study was carried out to compare the quality of image intensifier films with conventional post-operative radiographs. 79 sets of films were reviewed with particular reference to adequacy of fixation and possible joint penetration by the screws. No significant difference was noted between the two sets of films. We suggest that routine post-operative radiographs after femoral neck fracture fixation are unnecessary unless there is some clinical indication. This has significant implications in relation to patient discomfort, radiation exposure and cost-effectiveness.
