Ultrasound-Guided Targeted Injection to the Anterior Labral-Ligamentous Complex of the Shoulder: A Cadaveric Feasibility Study for Regenerative Therapy.
Article in Bioengineering (Basel, Switzerland), 2026. 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
The anterior labral-ligamentous complex (ALLC), formed by the integration of the anterior inferior glenohumeral ligament and anterior glenoid labrum, plays a critical role in shoulder stability and represents a potential target for regenerative injection therapy. However, precise ultrasound-guided targeting of this capsular-labral interface has not been anatomically validated. This feasibility cadaveric study evaluated the accuracy of ultrasound-guided in-plane injection directed at the ALLC at its glenoid attachment. A fresh-frozen human cadaver specimen was examined in the supine position with the shoulder in external rotation. Stepwise lateral-to-medial and cranial-to-caudal ultrasound scanning was performed to localize the ALLC. A 23-gauge needle was advanced in a cranial-to-caudal in-plane trajectory, and 1-2 mL of red filler was injected into the capsular-labral interface. Subsequent layer-by-layer dissection was conducted to assess injectate localization. In both shoulders (2/2), red filler was confined within the ALLC without extra-capsular leakage, diffuse intra-articular pooling, or neurovascular staining. These findings demonstrate the anatomical feasibility of ultrasound-guided targeted delivery to the anterior capsular-labral complex. This proof-of-concept study provides foundational anatomical validation for the development of regenerative injection protocols directed at the shoulder capsular-labral enthesis.
