Direct anterior approach in lateral position achieves superior cup orientation in total hip arthroplasty: a radiological comparative study of two consecutive series.
Article in International orthopaedics, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
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
introductionAlthough the advantages of total hip arthroplasty (THA) using the direct anterior approach (DAA) have been well documented, DAA in the supine position is limited by the difficulty in exposing the acetabulum and femur, which may result in implant malpositioning and intra-operative complications. Recent studies have reported that DAA-THA in the lateral position can achieve satisfactory clinical and radiographic outcomes. The aim of this study was to investigate the difference in implant alignment between two patient cohorts that underwent primary THA by DAA and the traditional posterolateral approach (PLA) in the lateral position.
methodsA total of 208 THAs (110 using DAA and 98 using PLA) were retrospectively analyzed.
resultsThe cup anteversion angle was closer to the target anteversion angle, and the accuracy of cup orientation was superior in the DAA group. A total of 82 (74.5%) DAA-THA and 56 (57.1%) PLA-THA cases showed successful inclination and anteversion angles (p = 0.008) of the implant. In addition, 90 (81.8%) DAA-THA and 67 (68.4%) PLA-THA cases had successful anteversion angle (p = 0.024). There was no significant difference between the two groups in terms of successful inclination angle (98 vs. 81, p = 0.181), as well as in the stem alignment in both coronal and sagittal planes.
conclusionTHA using DAA in the lateral position can achieve superior cup orientation compared to PLA while maintaining the stem alignment.
