Effect of digital navigation during anterior-approach total hip arthroplasty on patient outcomes.
Article in Canadian journal of surgery. Journal canadien de chirurgie. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundFluoroscopic guidance is a well-established technique in anterior-approach total hip arthroplasty (AA-THA) to enhance appropriate implant size and positioning, and to address potential complications, such as leg-length discrepancy (LLD). The primary objective of this study was to assess whether the implementation of a noninvasive fluoroscopy-assisted digital-navigation software improved the accuracy of postoperative leg length in AA-THA.
methodsWe conducted a retrospective cohort study involving patients who were identified from the prospectively collected patient-level provincial administrative data repositories. We extracted outcome data and measured leg lengths on postoperative radiographs.
resultsA total of 435 patients were identified. After exclusion, 400 patients were included in the study, with 247 in the navigation-software cohort. There was no significant difference between the groups with respect to demographic data. In the navigation-software cohort, we found no significant difference between the achieved LLD and zero LLD, whereas we found a significant difference in the fluoroscopy-only cohort (
conclusionThe use of navigation software in AA-THA is safe and effective to achieve more accurate postoperative leg length. Despite the increase in fluoroscopic time, there was a small but statistically significant reduction in operative time. The value of such technology would be expected to substantially increase if used during the learning curve when introducing AA-THA to contemporary practice.
