Automated Impaction Improves Femoral Component Canal Fit in Total Hip Arthroplasty: A Matched Study.

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
Background: Automated impaction in total hip arthroplasty (THA) is a new technology in femoral canal preparation. Recent studies have shown that it improves component alignment and fit and reduces operative time. The purpose of our study is to further investigate this technology's impact on femoral component canal fit, fracture risk, and operative time. Methods: We conducted a retrospective, matched analysis of 274 patients who underwent THA via automated impaction (N = 137) or manual impaction (N = 137). Postoperative radiographs were assessed to measure canal fill (CF) at the level of the neck cut, the lesser trochanter (LT), and 10 mm above (LT+10) and 60 mm below (LT-60) the LT. The average CF across these measurement points was calculated. The incidence of intraoperative fracture and average CF percentage were compared between the two cohorts. Results: The average CF percentage was significantly higher in the automated cohort (79.6 ± 5.6) than in the manual cohort (76.3 ± 5.6) ( Conclusions: Our study results suggest that automated femoral canal impaction improved CF and reduced operative time without introducing additional risk of intraoperative fracture in THA. Of note, these results cannot determine whether automated impaction has clinical benefit with respect to pain, function, or survivorship of the femoral component.
