Vascular structures and relationship to intramuscular fat in supraspinatus muscle following tendon detachment and reattachment – an experimental study in rabbits

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
