SUMMARY Background. The critical shoulder angle (CSA) has been used as a tool for identifying patients with high risk of developing a rotator cuff tear (RCT). A CSA angle larger than 35 degrees has been shown to be associated with increased risk of RCT. The aim of this study was to determine if this concept is applicable to … Continued
SUMMARY Skeletal muscle consists of heterogeneous cell populations that work in concert to support musculoskeletal homeostasis and regeneration in the context of acute injury and chronic disease. In this past decade, the recently discovered sub-population of muscle resident stem cells known as fibro-adipogenic progenitors (FAPs) have been implicated in the pathogenesis and regenerative response to a number of … Continued
Background. Supraspinatus (SSP) tendon tear leads to intramuscular fat accumulation and the mechanisms are unknown. We investigated changes in SSP muscle vascularization and association with intramuscular fat following SSP tendon detachment with or without reattachment. Methods. Sixty-six rabbits underwent SSP tendon detachment. In groups of ten, thirty rabbits were sacrificed 4, 8, and 12 weeks … Continued
