AI Article Synopsis
- The study investigated the presence of the rotator cable during shoulder arthroscopy, focusing on its prevalence in relation to patient age and rotator cuff tears.
- Patients included were aged 16 and older, while those with more complex cuff tears or poor video quality were excluded.
- Results indicated that older patients (averaging 52.1 years) were more likely to have the rotator cable, and there was a notable association between the cable's presence and the severity of rotator cuff tears, confirming the study's hypothesis regarding age.
Article Abstract
Background: This study evaluated the presence of the rotator cable intraoperatively and compared its prevalence according to both patient age and rotator cuff integrity. The study hypothesis was that the cable would be more prevalent in older patients and patients with partial-thickness tears.
Methods: Patients who were undergoing shoulder arthroscopy and were aged at least 16 years were included in this study, whereas those who had a cuff tear of more than 1 tendon or who had a video with poor visualization of the rotator cuff insertion were excluded. Intraoperative videos were collected, deidentified, and distributed to 7 orthopedic surgeons to define rotator cable and cuff tear characteristics.
Results: A total of 58 arthroscopic videos (average patient age, 46 years; range, 16-75 years) were evaluated. The observers were in the most agreement on identifying the presence of a cable, with a κ coefficient of 0.276. Patients with the rotator cable were significantly older than those without it (mean age, 52.1 years vs. 42.5 years; P = .008), and a positive and significant correlation was found between rotator cable presence and increasing patient age (r = 0.27, P = .04). A significant association was noted between tear degree and cable presence (P = .002). There was no significant association with cable presence in patients with a full-thickness tear.
Conclusions: In this study, an intraoperative analysis was performed to define the presence of the rotator cable and correlate this with both patient age and rotator cuff integrity. The hypothesis was confirmed in that patients older than 40 years had a significantly higher rotator cable prevalence.

Objective: This study aimed to compare the clinical and functional outcomes of patients with large posterosuperior rotator cuff tears between those with intact rotator cables (crescent-shaped tears) and those with repaired rotator cables (U-, V-, or L-shaped tears).
Methods: Eighty-two patients with a mean age of 64.05 ± 9.

Massive rotator cuff tears constitute approximately 20% of all rotator cuff tears. Poor tissue quality or significant retraction can lead to failure of the repair. The anterior rotator cuff cable is essential in transmitting force to the proximal humerus and serves as the main load-bearing structure within the supraspinatus.

Background: The use of renewable energy for sustainable and climate-neutral electricity production is increasing worldwide. High-voltage direct-current (HVDC) transmission via underground cables helps connect large production sides with consumer regions. In Germany, almost 5,000 km of new power line projects is planned, with an initial start date of 2038 or earlier.

Purpose: This study sought to evaluate the biomechanical properties of the interface between the rotator cuff and the semicircular humeral ligament or rotator cable (RCa) using histological and biomechanical techniques.
Methods: Out of 13 eligible cadaver specimens, 5 cadaver shoulders with an intact rotator cuff were included, 8 were excluded due to an injured rotator cuff. The histological study enables us to describe the capsule-tendon interface between the infraspinatus tendon (IST) or supraspinatus tendon (SST) and RCa, and to detect loose connective tissue layers to determine their precise location and measure their length along the interface.

Article Synopsis
- The study aimed to analyze the anatomical connections between rotator cuff muscles and the rotator cable using cadaveric shoulders.
- 30 shoulders from 20 cadavers were dissected to observe the attachment and orientation of the rotator cable, while assessing the presence and severity of shoulder pathologies.
- Findings revealed that the infraspinatus muscle had a looser attachment to the rotator cable compared to the supraspinatus and teres minor, suggesting different functional roles which may be influenced by shoulder pathology.
