Résumé
To determine whether a fluoroscopy-based navigation system would improve tip-apex distance (TAD) compared with the conventional technique. Randomized controlled trial. Level 1 trauma center. A total of 161 patients were screened for inclusion in the study. After meeting inclusion and exclusion criteria, 31 patients were randomized (n = 18 navigated vs. n = 13 control group), with the patient blinded to the result. Fluoroscopy-based navigated guidance of lag screw length and position. Average TAD and the proportion of TAD over 25 mm. TAD was lower in the navigated group compared with the control group (mean = 17.5 vs. 24.2 mm; P = 0.0018). No navigated cases exceeded the 25 mm TAD threshold, compared with 39% of conventional cases (P = 0.0076). Navigation resulted in fewer drilling attempts compared with the conventional technique (median = 1 vs. 4 attempts; P < 0.0001). We detected no significant differences in operation time or total number of fluoroscopic images (P > 0.05). Fluoroscopy-based computer navigated Gamma nailing for intertrochanteric fractures improved TAD and reduced the number of drilling attempts without increasing operation time compared with the conventional fluoroscopy-guided technique in a teaching hospital setting. Therapeutic Level I. See Instructions for Authors for a complete description of levels of evidence.
