Comparative analysis of the quality of the cement mantle in hip hemiarthroplasty after femoral neck fracture between three different surgical approaches: a single-center retrospective observational study.

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
purposeAchieving the initial stability of implants is necessary for hip hemiarthroplasty (HHA), especially in elderly patients, and this can be achieved with a cement mantle of quality. The direct anterior approach (DAA) for HHA lately has shown positive results. However, evidence is lacking of HHA in elderly patients with osteoporosis after femoral neck fracture (FNF). This study compares differences in cement mantle quality after HHA, its complications, radiological outcomes and functional status in elderly patients with FNF intervened through different approaches.
methodsA non-interventional, retrospective case-control study was conducted. 150 cases were selected based on the surgical approach (DAA, DLA and PLA) in a 1:1:1 proportion between 2018 and 2019. Under 75 years old suspicion or confirmation of a pathological fracture were excluded. Antibiotic-loaded cement was utilized. Cement preparation involved vacuum centrifugation and standard instructions for preparation canal and filling, and prosthesis placement were followed.
resultsNo statistically significant differences in cement mantle quality, radiological outcomes, and the majority of the postoperative complications and functional status considering the surgical approach (p > 0.05). However, the DAA was associated significantly with shorter hospital stays (8.3 days vs 11.3 and 13 days for DLA and PLA) a decrease in postoperative blood transfusion (22% vs 34% and 53%), and lower rate of loss of walking (8% vs 20% and 28.6%).
conclusionThe DAA for HHA in patients with FNF provides a high-quality cement mantle, similar to other approaches. Also, the DAA shows advantages like shorter hospital stays and lower transfusion rates in elderly patients.
