Abstract
Routine postoperative radiographs following hip hemiarthroplasty are commonly undertaken despite it being suggested that they can cause delays to discharge, discomfort to patients and unnecessary radiation. Our study considered the necessity of these post-operative radiographs.
A retrospective search was conducted of all hemiarthroplasty procedures on the Royal Cornwall Hospital database. These were reviewed for cases where re-operation was conducted within 6 weeks. Notes and post-operative check radiographs of those who underwent re-operation were reviewed to determine how essential radiographs were in diagnosing complications requiring re-operations.
A total of 1557 hemiarthroplasty operations were identified. There were 37 incidences of re-operation within 6 weeks. 29 cases had normal check radiographs. 8 dislocations were picked up on post-operative radiographs. In all but one of these cases, clinical suspicion of complication had been raised prior to the radiograph. In the remaining case documentation was poor and no firm conclusion as to clinical suspicion could be drawn.
Our review of over 1500 hemiarthroplasty cases, demonstrated one incident where the check radiograph solely diagnosed an abnormality needing intervention that might not have been apparent clinically. We thus suggest that check radiographs following hip hemiarthroplasty should not be routinely ordered for all patients.
