Reverse total shoulder arthroplasty in massive rotator cuff tears: does the Hamada classification predict clinical outcomes?
Observational study in Archives of orthopaedic and trauma surgery, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers, 1 of them a synthesis that pooled 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.
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
introductionReverse total shoulder arthroplasty (RTSA) is a widely recognized treatment to reduce pain and improve shoulder function for patients in various disease stages of cuff tear arthropathy (CTA). However, it remains unclear whether outcomes after RTSA depend on the preoperative stage of CTA. Therefore, this study evaluated whether the Hamada classification influences midterm clinical outcomes after RTSA. MATERIALS AND
methodsIn this multicenter observational study, patients underwent inverted bearing RTSA for massive rotator cuff tears or CTA. Shoulders were grouped into those with (Hamada grades 4a, 4b, and 5) and those without (Hamada grades 1, 2, and 3) glenohumeral arthritis. Clinical outcomes, including range of motion, Constant score, American Shoulder and Elbow Surgeons score, and visual analog scale for pain and satisfaction, were determined preoperatively and at 24 and > 30 months. All complications were recorded, and survival free from any implant component revision was calculated.
resultsOverall, 202 patients (211 shoulders) were treated with RTSA at a mean age of 75.8 ± 6.6 years (range 41.9-91.6 years). Of these, 144 patients (151 shoulders) were available for a mean follow-up of 79.9 ± 24.7 months (range 30.2-132.3 months). No significant between-group differences were found for clinical outcomes at 24 and > 30 months (P > 0.05). Furthermore, the Hamada classification did not correlate with clinical outcomes at 24 (P = 0.98) and > 30 months (P = 0.29). Revision-free implant component survival was similar between groups (P = 0.17). Postoperative complications were found in 11 shoulders, of which 10 required revision.
conclusionsInverted bearing RTSA was found to be an effective treatment with similarly good midterm clinical outcomes, similar revision rates, and high implant survival rates in every stage of massive rotator cuff tears. Overall, the preoperative Hamada classification did not influence clinical outcomes or complications after RTSA.
