“…The outlier of 145° was in an obese patient, whose abdomen most likely pushed her elbows away from her body requiring greater internal rotation of her arms to place her hands in her lap when getting vaccinated. Among 238 consecutive patients at an academic medical center with rotator cuff diagnoses at surgery, 56.7% exhibited bone lesions at the posterior facet and 22.7% at the anterior facet on their pre-operative MRI [ 38 ], a distribution roughly corresponding to the relative size of the facets [ 39 ]. This is higher than the prevalence of bone lesions in the normal population, which is 13–27% based on radiographs [ 38 ].…”

Background: Chronic shoulder pain occurs rarely after a vaccination and is hypothesized to arise from the effects of unintentional vaccine injection into the subacromial bursa, rotator cuff, capsule or underlying bone. The avascular nature of the rotator cuff, as well as unknown genetic and environmental factors, may predispose to the persistence of pain and disability, referred to as vaccination-related shoulder dysfunction and shoulder injury related to vaccine administration (SIRVA). Methods: Ultrasonography, sonopalpation and ultrasound-guided anesthetic injections were used to locate the anatomical source of chronic (mean 20, range 8-42 months) shoulder pain after a vaccination in a consecutive series of 5 patients. Subsequently ultrasound-guided ultrasonic aspiration and debridement was performed using a 2.1 mm outer cannula with an inner needle vibrating at 28 kHz. Outcomes were assessed using the Quick Disabilities of the Arm, Shoulder and Hand (QDASH) scale at 2, 4, 12, 24 weeks and 1 year. Results: The distal infraspinatus and teres minor tendons, their insertions and or the adjacent bone were the source of pain in all 5 patients. The mean QDASH score improved from 65 points to 11 points at 2 weeks (P ¼ 0.001), and to 1 point at 4 weeks after the procedures (P ¼ 0.003). Improvements in pain and function remained stable at 1 year in 3 patients, for at least 24 weeks in 1 patient who died of unrelated causes, and 1 year in 1 patient for posterior shoulder pain who after a pain free interval developed anterior shoulder pain related to his previously asymptomatic osteoarthritis (P ¼ 0.013). Conclusion:The distal infraspinatus and teres minor tendons, their insertions and adjacent bone are a common source of chronic shoulder pain after a vaccination. Ultrasound-guided ultrasonic aspiration and debridement is a potentially effective treatment for resolving pain and restoring function.

“…The ES cuff was embedded into a region of 150 mm 2 (5 × 15 mm), an area that roughly reflects the dimensions of the footprint of the supraspinatus tendon enthesis, measured from human cadaveric specimens. [72,73] The ES cuff had a maximum force of failure of 226.8 ± 46.9 N, indicating a clear potential for clinical application from a mechanical point of view. Indeed, sutures used for rotator cuff surgeries typically fail in the range of 184-359 N, [11,[74][75][76]77] although this is heavily dependent on suture material, suture configuration, and tissue quality (tendon and bone).…”

Rotator cuff tendon tears are common injuries of the musculoskeletal system that often require surgical repair. However, re‐tearing following repair is a significant clinical problem, with a failure rate of up to 40%, notably at the transition from bone to tendon. The development of biphasic materials consisting of soft and hard components, which can mimic this interface, is therefore promising. Here, a simple manufacturing approach is proposed that combines electrospun filaments and 3D printing to achieve scaffolds made of a soft polydioxanone cuff embedded in a porous polycaprolactone block. The insertion area of the cuff is based on the supraspinatus tendon footprint and the size of the cuff is scaled up from 9 to 270 electrospun filaments to reach a clinically relevant strength of 227N on average. The biological evaluation shows that the biphasic scaffold components are noncytotoxic, and that tendon and bone cells can be grown on the cuff and block, respectively. Overall, these results indicate that combining electrospinning and 3D printing is a feasible and promising approach to create soft‐to‐hard biphasic scaffolds that can improve the outcomes of rotator cuff repair.
