|January 23, 2015
Summary
Intraoperative fluoroscopy did not improve total hip arthroplasty (THA) component accuracy or reduce complications. This technique increased operative time and costs, leading to a recommendation against its use in uncomplicated primary THA.
Area of Science:
- Orthopedic Surgery
- Medical Technology Evaluation
Background:
- Accurate component placement is crucial for successful total hip arthroplasty (THA) outcomes.
- Technology-assisted techniques may enhance accuracy but face barriers due to resource requirements.
Purpose of the Study:
- To compare primary THA procedures with and without intraoperative fluoroscopic guidance.
- To evaluate the impact on prosthesis placement accuracy, operative time, and postoperative complications.
Main Methods:
- Review of 341 consecutive primary THA cases (September 2007 - January 2010).
- Measurement of acetabular inclination, leg length discrepancy, and femoral offset using postoperative radiographs.
- Comparison of complication rates and operative times between fluoroscopy-guided and freehand groups.
Main Results:
- No significant differences in acetabular inclination, leg length discrepancy, or offset discrepancy between groups.
- Similar postoperative complication rates (8.1% control vs. 5.3% study group).
- Significantly longer operative time in the fluoroscopy-guided group (59.8 min vs. 52.8 min).
Conclusions:
- Intraoperative fluoroscopy does not appear to improve prosthesis accuracy or decrease complications in primary THA compared to a freehand technique.
- Increased operative time and costs associated with fluoroscopic guidance.
- Discourages routine use in uncomplicated primary THA at high-volume centers.
