Component orientation measurements in total hip arthroplasty using an inertial measurement unit-based smart trial system.
Article in Arthroplasty (London, England), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundIntraoperative measurement of component orientation represents a basis for optimizing outcomes after total hip arthroplasty (THA). Although the use of computer navigation systems in THA has improved the accuracy of component positioning, they have not gained widespread popularity due to their complexity, time demands, and time-consuming protocols.
methodsWe developed an Inertial Measurement Unit-based Hip Smart Trial system (IMUHST) to assist with intra-operative monitoring of hip posture. An in vitro validation experiment was conducted using a sawbones with a three-dimensional (3D) measurement model as the reference standard.
resultsThe absolute mean error, Bland-Altman analysis, and Intra-class Correlation Coefficient revealed that the accuracy and precision of this system meet the threshold for clinical application.
conclusionsIn conclusion, this in vitro validation demonstrates that the IMUHST system provides accurate component orientation measurements while eliminating the cost and complexity of optical navigation, offering a practical solution for widespread adoption. Video Abstract.
