Introduction
Currently, there are no clear guidelines regarding the optimal settings for immediate postoperative imaging following total hip arthroplasty (THA). Authors’ primary aim was to determine the preferred setting for postoperative radiographs by comparing a technical quality of imaging performed in postanesthesia care unit (PACU) versus operating room (OR).
Materials and methods
Our study is a retrospective comparison of quality of postoperative radiographs following THAs, performed in PACU versus OR. The evaluated factors included a technical quality (penetration, collimation and presence of foreign bodies), proper patient positioning, and clinical significance of the imaging expressed in number of decisions to perform immediate revision surgery that were based on postoperative imaging.
Results
267 radiographs of patients who underwent primary unilateral THA were evaluated (139 performed in PACU and 128 in OR). In terms of technical quality, PACU radiographs were characterized by better penetration (69.1% vs 27.3%, p < 0.001) and less foreign bodies in the field (95.7% vs 83.6%, p < 0.001), but less adequate collimation (41.7% vs 79.7%, p < 0.001). There was a significant difference in the number of radiographs obtained without any noteworthy technical errors – 24 (17.3%) in PACU group vs 10 (7.8%) in OR group.
Conclusion
Postoperative X-rays performed in the PACU were characterized by better technical quality compared to postoperative radiographs performed in OR. We, therefore, suggest to perform immediate postoperative evaluation in PACU to provide baseline radiographs of higher quality for future follow-up.
