Opportunistic Screening for Local Osteoporosis of the Proximal Humerus on the Basis of Hounsfield Units: A Study of Patients With Rotator Cuff Tears.
Article in Orthopaedic surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectivesThe accuracy of dual-energy x-ray absorptiometry (DXA) in predicting proximal humerus osteoporosis in patients with rotator cuff tears (RCTs) undergoing arthroscopic rotator cuff repair (ARCR) is uncertain. The aim of this study was to assess the correlation of computed tomography (CT) Hounsfield units (HU) and the deltoid tuberosity index (DTI) with bone mineral density (BMD), and to evaluate the predictive value of HU values for implant selection.
methodsThis study analyzed the preoperative shoulder CT scans and x-rays of 184 patients who underwent ARCR. Preoperative CT scans were utilized to assess the multiple anatomical parts of the proximal humerus to ascertain the HU values, whereas preoperative x-rays were analyzed to derive the DTI. Among them, 104 patients with preoperative DXA data were grouped according to the WHO diagnostic criteria for osteoporosis to establish the threshold HU values. The correlation between HU values and DTI and the lowest T score on DXA was studied, and the relationship between the HU value and the type of implant selected was discussed. The Pearson correlation coefficient was employed to examine the relationship between HU values, DTI, and T scores. And the Spearman correlation coefficient was employed to examine the relationship between HU values and enhanced fixation.
resultsThere was a significant correlation between the HU values and DTI and the lowest T score (r
conclusionProximal humeral HU values were significantly correlated with DTI and the lowest T score on DXA. When the HU values in the proximal humerus in patients with RCTs fall below the thresholds, the surgery should be carefully planned. No correlation exists between HU values and enhanced fixation, thus further investigation through group studies is warranted. LEVEL OF EVIDENCE: Level III, study of nonconsecutive patients, diagnostic study.
