Are routine postoperative X-rays needed following surgery for hallux valgus? An evaluation of their use after scarf osteotomy.
BACKGROUND
Postoperative X-rays, following a scarf osteotomy, are generally carried out as routine. The aim of this study was to assess the value of performing such investigations.


METHODS
Retrospective data were collected regarding all scarf osteotomies performed by three consultant orthopaedic surgeons at a large teaching hospital. A review of routine postoperative X-rays was carried out.


RESULTS
A total of 274 scarf osteotomies were included in the study. Of these, 95% were followed by at least one routine postoperative X-ray. In total, 412 X-rays were performed of which 11% were not commented upon by a radiologist or a surgeon. Of the X-rays with comments from both specialists, only one case was reported as abnormal by both radiologist and surgeon, with no change in management made as a result of these reports. In two cases, changes to standard management were made on the basis of the routine postoperative X-rays and only one of these was implemented solely on the basis of the routine postoperative images.


CONCLUSIONS
The value of postoperative X-rays following a scarf osteotomy is questionable. We propose, on the basis of this study, that, unless clinically indicated, the routine use of postoperative X-rays following a scarf osteotomy should be abandoned.
