Operative outcomes, complications, and functional recovery of lateral-position direct anterior approach versus posterolateral approach in hemiarthroplasty: a retrospective cohort study.
Article in BMC surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundHip replacement is a standard treatment for femoral neck fractures, but the optimal surgical approach remains uncertain. This study aimed to compare the clinical outcomes of the lateral-position direct anterior approach (DAA) and the posterolateral approach (PLA) in patients undergoing hemiarthroplasty. MATERIALS AND
methodsThis retrospective cohort study analyzed clinical data from 56 patients with femoral neck fractures who underwent hemiarthroplasty between February 2019 and September 2022. Patients were classified into a PLA group (n = 28) and a DAA group (lateral-position DAA, n = 28). Perioperative indices, postoperative pain assessed by the visual analogue scale (VAS), Harris Hip Score, Barthel Index, quality-of-life measures, and early postoperative complications were evaluated.
resultsThe DAA group had a shorter operation time (100.54 ± 11.64 min vs. 110.48 ± 22.32 min, p = 0.041), smaller incision length (9.31 ± 0.31 cm vs. 12.31 ± 1.21 cm, p < 0.001), less intraoperative blood loss (214.95 ± 32.22 mL vs. 268.49 ± 23.53 mL, p < 0.001), and shorter hospital stay (10.68 ± 3.31 days vs. 17.49 ± 2.21 days, p < 0.001) compared with the PLA group. VAS scores were lower in the DAA group on postoperative days 1, 3, and 7 (all p < 0.001). Harris Hip Scores and Barthel Index scores were higher at discharge and at 1 and 3 months postoperatively (all p < 0.001). The incidence of early postoperative complications was lower in the DAA group than in the PLA group (7.14% vs. 42.86%, p = 0.002), including a reduced rate of hip dislocation (3.57% vs. 25.00%).
conclusionLateral-position DAA using conventional instruments was associated with improved perioperative outcomes, faster early functional recovery, and fewer early complications compared with PLA in this retrospective cohort. These findings suggest that lateral-position DAA may be a feasible alternative approach; however, prospective studies are required to confirm these results.
