Differences in range of motion with the same combined anteversion after total hip arthroplasty.
Article in International orthopaedics, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 papers.
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
purposeWe investigated the various impingement angles (including both bony and prosthetic impingement) and impingement types that can occur after THA, even when the same combined anteversion parameter is used. We also investigated the relationship between impingement angle and acetabular morphology or femoral anteversion.
methodsWe evaluated 83 patients with no hip arthritis. We divided them into six groups according to acetabular CE angle (≤15°, >15-≤25°, and >25°) and femoral anteversion (≤20° and >20°). Using three-dimensional templating software, we changed stem and cup anteversion to satisfy a combined anteversion (CA) of 50° in each hip (stem anteversion + cup anteversion = 50°) and investigated the resulting impingement angles.
resultsEven with the same CA, differences in impingement angle occurred: 18.3° ± 7.2° with flexion, 30.2° ± 9.7° with internal rotation at 90° flexion, 20.2° ± 12.5° with extension, and 26.2° ± 7.8° with external rotation. As stem anteversion increased, the impingement type changed from prosthetic impingement to bony impingement in flexion and internal rotation and from bony impingement to prosthetic impingement in extension and external rotation. The flexion angle and internal rotation angle at 90° flexion increased (p < 0.016) as CE angle decreased. There were no significant differences between high and low femoral anteversion.
conclusionsCombined anteversion theory should be used with care because of large differences in impingement angles. A stem anteversion of 30° and cup anteversion of 20° appear to be ideal for obtaining a larger impingement angle under this condition.
