Direct anterior approach and dual mobility cup: the "head-first" reduction technique: a technical note and early case series.
Article in Musculoskeletal surgery, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
purposeLess invasive direct anterior approach (DAA) and dual mobility cup (DMC) are increasingly adopted in practice over the last decade. Their use aims to reduce, as much as possible, soft tissue dissection and dislocation rate. This study aims to present a novel surgical technique to reduce a DMC prosthesis during a DAA easily.
methodsA mildly modified version of the direct anterior approach is proposed. When leg lengths, stability, impingement, and tension have been checked, the trial stem is disassembled in situ, dislocated, and removed, leaving the space to exchange the trial double mobility head with the definitive one. When the definitive stem is inserted, the surgeon guides and helps the assistant to match the trunnion in the double mobility head. As soon as the components are matched, the traction is released, and the unit is impacted by an alternation of axial traction and release.
resultsOf 164 patients who underwent primary total hip arthroplasty (December 2016-May 2017) by a single surgeon, a double mobility cup through DAA and the "head-first" technique was performed in 26 patients (15.8%). The mean operative time was 130 min (85-220 min; SD 34.28). No significant complications occurred during the mean follow-up of 23.6 months.
conclusionsSpecific difficulties can be anticipated when pairing dual mobility cup and direct anterior approach. The "head-first" technique is a useful technique in reducing the possible difficulties related to the reduction of double mobility cup through a less invasive direct anterior approach.
