Early clinical efficacy of hip hemiarthroplasty via the SuperCap approach vs. the posterolateral approach in elderly patients with femoral neck fractures: a randomized controlled trial.

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
Objective: To evaluate the clinical efficacy, perioperative trauma, and early functional recovery trajectory of hip hemiarthroplasty (HA) via the SuperCap approach vs. the traditional posterolateral approach (PLA) in patients aged ≥75 years with displaced femoral neck fractures (FNFs). Methods: A prospective, single-center, randomized controlled trial was conducted between July 2023 and January 2024, initially recruiting 52 geriatric patients with displaced FNFs (Garden types III and IV). Forty-eight patients (24 per group) completed the 6- and 12-month functional assessments. The primary outcome was the Harris Hip Score (HHS) at 6 months postoperatively. Secondary outcomes encompassed perioperative metrics, early mobility indices [Time to Mobilization, Timed Up and Go (TUG)], pain Visual Analog Scale (VAS), laboratory biomarkers of muscle trauma and inflammation [e.g., creatine kinase (CK), hemoglobin (Hb)], radiographic positioning, and complications. Results: The primary outcome (6-month HHS) showed no statistically significant difference between groups (91.04 ± 1.46 vs. 90.67 ± 1.97; mean difference 0.37; 95% CI -0.64 to 1.38; Conclusion: While achieving comparable short-term functional outcomes to the traditional PLA, the SuperCap approach significantly minimizes skeletal muscle trauma, reduces perioperative blood loss, and accelerates early functional rehabilitation. It serves as a highly effective, tissue-sparing option that facilitates rapid postoperative recovery in vulnerable geriatric patients.
