Great tuberosity fixation does not affect healing and clinical outcomes in RSA performed in proximal humeral fractures in elderly patients.

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
purposeAims of our study were to define whether the great tuberosity (GT) positioning fixation in reverse shoulder arthroplasty (RSA) after proximal humeral fracture (PHF) could predict tuberosity healing and its impact on clinical outcomes.
methodsWe enrolled 59 patients treated with cementless reverse shoulder arthroplasty after PHF in our institute between 2012 and 2018. The mean follow-up was 57 months (± 23.4). We divided patients into two groups according to GT positioning after fixation: Group 1 GT in contact and Group 2 GT detached at least 1 mm from humeral diaphysis. Clinical and radiographic evaluations were conducted at last follow-up.
resultsOverall GT healing rate was 64.4%, (Group 1 70.7%-Group 2 50%). A statistically significant difference (P = 0.047) was found in cortical thickness narrowing at one-third of stem length. We found a correlation between lateral cortical narrowing and GT fixation in non-anatomical position, but we observed no statistically significant differences about GT healing according to GT anatomical or non-anatomical fixation. No differences were found in shoulder function in patients whose tuberosity was healed or failed to heal.
conclusionGT reduction is not a predictive factor for GT healing; external stress shielding, instead, seems to be decreased in patients with postoperative anatomically reduced GT. In our study, GT healing did not affect clinical outcomes or patient's satisfaction in elderly low-demanding patients.
