Structure-function and developmental biology results, and (iv) applying these strategies to improve tendon-to-bone healing figure 1: tendons attach to bone across the enthesis, a functionally graded fibrocartilaginous transitional tissue ( left: toluidine blue-stained section from an adult rat supraspinatus tendon enthesis. If the tendinitis occurs at the point where supraspinatus tendon insert to the bone, it is called enthesitis who gets supraspinatus tendinitis anyone can get tendinitis, but it is most often seen in throwing athletes (for example swimmers, football player and volleyball player) and workers that perform repetitive overhead. Features of acute on chronic rotator cuff inflammatory enthesitis typical of ankylosing spondylitis chronic erosion with subchondral cystic change of the superolateral humeral head, at the insertion site of the supraspinatus tendon marked underlying marrow edema within the humeral head no high grade. Most full-thickness tears occur in the distal enthesis of the supraspinatus, but some may arise more proximally and leave a distal tendon stump attached to the greater tuberosity (figure 1-52 video 1-16) in long-standing tears, fluid is usually absent and the gap filled in by fibrous tissue and proliferating synovium (figure 1- 53). Figure 2: (2a) the fat-suppressed coronal t2-weighted image demonstrates a focal bursal surface fluid-filled defect of the supraspinatus portion of the rotator cuff (arrow) (2b) the sagittal t2-weighted image also demonstrates focal fluid signal within the cuff defect (arrow) extending to the cortex of the greater tuberosity.
Abstract: the purpose of this study was to find out whether supraspinatus repair delayed by up to12 weeks affects the formation of a new enthesis when compared to an immediate repair in 67 rabbits, the supraspinatus fibrocartilaginous enthesis of one shoulder was resected the tendon was attached. This assessment is necessary for anatomic-clinical correlations and for the proper choice of surgical approach and technique anteriorly situ- ated defects are more painful, whereas posterior lesions interfere more with function in a sagittal section viewed from the subscapularis to the infraspinatus, several segments can be. Purpose to quantify in a longitudinal study non-chondrocytic cells and chondrocytes, tissular architecture as well as extracellular matrix restoration during the formation of an enthesis following supraspinatus tendon attachment to the humerus methods in 89 rabbits, one supraspinatus fibrocartilaginous enthesis was.

The supraspinatus enthesis was prepared for examination by decalcifying the shoulder (humerus + scapula), embedding them in paraffin and sectioned, as previously described  the remaining 5 aged 12-wk hrlf and 5 aged nc shoulder samples were embedded without decalcification in methyl.
