Introduction

Accurate placement of acetabular components and femoral stems in total hip arthroplasty is imperative to improve clinical outcomes. The aim of this study was to compare component placement, stem alignment, leg length difference, surgical time and complications in patients with and without intraoperative fluoroscopy in patients undergoing Total hip arthroplasty.

Methods

Between 2015 and 2023, 187 patients who underwent total hip replacement in our clinic were retrospectively evaluated. There were 91 patients in the fluoroscopy group and 96 patients in the non-fluoroscopy group. Acetabular component placement, femoral stem alignment, leg length differences were compared between the groups on postoperative radiographs.

Results

The mean inclination, mean anteversion and mean femoral offset differences in the fluoroscopy group were 42.9° ± 7.08°, 9.62  ± 6.2 mm and 40.9° ± 6.89°, respectively, and the mean acetabular inclination, anteversion and femoral offset discrepancy in the non-fluoroscopy group were 48.74° ± 11.8°, 10.7  ± 6.9 mm and 45.44° ± 10.59°, respectively. When the groups were compared statistically, a significant difference was observed in terms of inclination and femoral offset (p: 0.001, p: 0.312, p: 0.002). In terms of femoral stem alignment, 8 patients in the fluoroscopy group had varus malalignment and 24 patients in the non-fluoroscopy group had varus malalignment. When the groups were compared statistically, a significant result was found (p: 0.003).

Conclusion

The study showed that the use of fluoroscopy improved acetabular component placement and femoral stem alignment, but intraoperative fluoroscopy significantly prolonged the surgical time.
