1 · What the graph read from 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.

2 · The registry

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

introductionDisplaced intracapsular femoral neck fractures (FNF) are the most frequent surgical pathology in orthopedics. Controversy surrounds optimal treatment, with little consensus, particularly in the elderly multimorbid at risk population. For over a decade, our institution adopts a standardized protocol for FNF, utilizing cemented hip hemiarthroplasty (HA) via the posterior approach. This study evaluates the outcomes of this approach, contributing to the ongoing debate and potentially guiding future treatment strategies. METHODOLOGY: This retrospective study included patients (≥ 60 years) who underwent HA for FNF from January 1, 2008, to June 30, 2019, at a University Hospital. Our primary endpoint was revision surgery for HA (rHA) within four years after HA. Secondary endpoints included hip-related and unrelated complications.

resultsOf 1001 patients, 40 (3.9%) underwent rHA. Indications were periprosthetic fractures (5; 0.5%), dislocation (15; 1.5%), suspected prosthetic joint infection (17; 1.7%), and acetabular erosion (3; 0.3%). Four-year mortality was 51%. Cox regression revealed age > 80 years (aHR 1.86, p < 0.001), ASA score III or IV (aHR 2.11, p < 0.001), and postoperative delirium (aHR 1.29, p < 0.05), as independent predictors of higher 4-year mortality. No difference was observed among patients with and without revision indication for ASA scores III or IV (64% vs. 64%; p = 0.912), surgery within 24 h (52% vs. 57%; p = 0.334), duration over 90 min (46% vs. 53%; p = 0.201), and surgery during the night shift (24% vs. 19%; p = 0.285). Board certification did not impact revision rates (39% vs. 39%; p = 1.000).

conclusionCemented HA is a safe and reliable treatment option for FNF, delivering consistent outcomes in the elderly multimorbid population, with low rates of rHA (3.9%). The posterior surgical approach, even in patients with heightened dislocation risk, remains a viable option. Timing of surgery (night/day) does not significantly affect revision rates, which could have substantial implications for surgical planning and healthcare resource allocation.
