Determining the closest distances from the coracoid base and tip to neurovascular structures in acute high-grade acromioclavicular joint injuries: a cadaveric study.

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
backgroundHigh-grade acromioclavicular (AC) joint injuries often require coracoclavicular (CC) stabilization, which increases the risk of neurovascular injury due to coracoid process proximity to vital structures. Previous intact AC joint measurements may have underestimated the surgical risks of high-grade injuries with altered anatomy. Therefore, this study investigated the distance from the coracoid base and tip to the adjacent neurovascular structures in simulated acute high-grade AC joint injuries.
methodsEight freshly frozen cadaveric specimens, consisting of four male and four female specimens, were subjected to simulated high-grade AC joint injuries via AC capsule and CC ligament transection and deltotrapezial fascia detachment. Closest distances from the coracoid base and tip to the lateral border of adjacent neurovascular structures were measured in the supine, beach chair, and lateral decubitus positions.
resultsThe distance from the coracoid base to the neurovascular structures varied significantly depending on the body position. The supine position provided the greatest distance, reducing the risk of neurovascular injury compared to the beach chair and lateral decubitus positions (p = 0.030 and p < 0.001, respectively). In contrast, the lateral decubitus position had the shortest distance, highlighting an increased risk of neurovascular injury.
conclusionsThis study demonstrates that the supine position provides the safest approach for minimizing neurovascular injury risk during surgical stabilization of high-grade AC joint injuries. These findings contribute to clinical practice by emphasizing the importance of patient positioning to optimize surgical safety and outcomes. CLINICAL TRIAL NUMBER: Not applicable.
