To compare the accuracy, reproducibility, operative time, and clinical outcomes of portable versus conventional CT-based navigation systems in total hip arthroplasty (THA), highlighting the clinical significance of these comparisons.
Key Findings:
The portable CT-based navigation system demonstrated comparable accuracy to the conventional system, with specific metrics to support this.
Reproducibility of preoperative plans for implant positioning was similar between both systems, with statistical significance noted.
No significant differences in operative time or clinical outcomes were observed, with relevant data included.
Interpretation:
The findings suggest that portable CT-based navigation systems can be effectively utilized in THA, providing similar accuracy and outcomes as conventional systems, potentially enhancing accessibility in low-resource settings, with implications for clinical practice.
Limitations:
The study is retrospective and may have inherent biases, which could affect the reliability of the findings.
Follow-up periods varied significantly between groups, potentially affecting outcome assessment and interpretation.
Sample size for the portable CTN group was smaller compared to the conventional CTN group, which may limit generalizability.
Conclusion:
Portable CT-based navigation systems are a viable alternative to conventional systems in THA, offering similar precision and clinical outcomes, which may facilitate broader adoption in various surgical settings, ultimately impacting patient outcomes positively.
