Late-presenting chronic humeral head collapse, Cruess stage V, managed with modular uncemented hemiarthroplasty.

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
Humeral head osteonecrosis may remain unrecognized until collapse and secondary arthropathy develop. A 44-year-old man presented with progressive right shoulder pain and restricted motion for 1 year. Radiographs and computed tomography showed advanced humeral head collapse with secondary glenohumeral arthropathy, most consistent with Cruess stage V osteonecrosis. Preoperative ultrasound demonstrated preserved rotator cuff continuity. Because joint-preserving procedures were not feasible, modular uncemented shoulder hemiarthroplasty was performed. This case illustrates the rationale for hemiarthroplasty in selected patients with stage V disease when destruction is predominantly humeral-sided, glenoid bone loss is limited, the rotator cuff continuity is preserved, and maintaining future revisionoptions is an important consideration.
