Thirty\u2010three fresh cadaveric shoulders (average age: 62 years; range: 39\u201083 years) were examined. A tensile load to failure was applied at a constant crosshead speed of 25.4 mm\/min to a 10 mm wide strip of the supraspinatus tendon that remained attached to the bone. Preexisting degenerative changes at the insertion were assessed and scored histologically and compared with the ultimate tensile stress. Twenty tendons failed at the insertion (the insertion group), and 11 failed in the midsubstance (the midsubstanee group). The histologic score of degeneration for the insertion group was significantly higher than that for the midsubstance group (p = 0.0026). There was a negative correlation between the ultimate tensile stress at the insertion and the degeneration score for the insertion group (r = \u22120.60; p = 0.013). Histologic observations revealed that disruptions of tendon fibers were located mostly in the articular half of the tendon and that they enlarged during mechanical testing in 90% of the specimens of the insertion group. It seems that degenerative changes at the supraspinatus insertion reduce the tensile strength of the tendon and constitute a primary pathogenetic factor of rotator cuff tear.<\/jats:p>","DOI":"10.1002\/jor.1100150514","type":"journal-article","created":{"date-parts":[[2005,2,24]],"date-time":"2005-02-24T10:47:57Z","timestamp":1109242077000},"page":"719-726","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":99,"title":["Degeneration at the insertion weakens the tensile strength of the supraspinatus tendon: A comparative mechanical and histologic study of the bone\u2010tendon complex"],"prefix":"10.1002","volume":"15","author":[{"given":"Hirotaka","family":"Sano","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hirotada","family":"Ishii","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alan","family":"Yeadon","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David S.","family":"Backman","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jacques A.","family":"Brunet","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hans K.","family":"Uhthoff","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2005,2,18]]},"reference":[{"key":"e_1_2_1_2_2","first-page":"80","volume-title":"Mechanics of Materials","author":"Beer FP","year":"1981"},{"key":"e_1_2_1_3_2","first-page":"89","article-title":"The histology of tendon attachments to bone in man","volume":"149","author":"Benjamin M","year":"1986","journal-title":"J Anat"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1177\/036354657900700206"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-199274050-00010"},{"key":"e_1_2_1_6_2","unstructured":"CodmanEA:The Shoulder pp65\u2013107.
