Direct anterior approach versus posterolateral approach hemiarthroplasty for treating femoral neck fractures in the elderly: a prospective controlled study.
Trial report in Journal of orthopaedic surgery and research, 2025. 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
objectiveTo compare the clinical efficacy of the direct anterior approach (DAA) versus the posterolateral approach (PLA) in hemiarthroplasty for treating femoral neck fractures in elderly patients.
methodsIn a prospective controlled study, elderly patients with femoral neck fractures undergoing hemiarthroplasty at Fujian Provincial National Regional Trauma Center from February 2023 to February 2025 were randomized to the DAA or PLA group. Primary outcomes included Harris Hip Score (preoperatively, and at 1 week, 1 month, and 3 months postoperatively) and Visual Analogue Scale (VAS) pain score. Secondary outcomes included operative time, intraoperative blood loss, transfusion rate, perioperative changes in hemoglobin and creatine kinase, complications, limb length discrepancy, drainage volume, ICU admission rate, hospital stay, and other clinical indicators.
results102 patients completed the surgery and 3-month follow-up (DAA: 50; PLA: 52). Baseline characteristics and comorbidities were comparable between groups (P > 0.05). The DAA group had a significantly higher Harris Hip Score at 1 week postoperatively compared to the PLA group (60.97 ± 2.78 vs. 58.92 ± 2.49, P < 0.001), though no significant differences were noted at 1 or 3 months. The overall trend in Harris Hip Score differed significantly between the groups (P = 0.006). VAS pain scores showed no difference at any time point. Limb length discrepancy postoperatively was significantly less in the DAA group [1.725 (0.930, 3.595) mm] than in the PLA group [3.935 (1.940, 5.458) mm, P < 0.001]. No significant differences were observed in operative time, blood loss, transfusion rate, perioperative marker changes, complications, ICU admission, hospital stay, or mortality.
conclusionDAA in hemiarthroplasty does not increase operative time, blood loss, or complications compared to PLA. DAA provides better early postoperative functional outcomes and less limb length discrepancy in elderly patients with femoral neck fractures.
