AB  - BACKGROUND: In arthroscopic surgery, the suture anchor technique has become 
      popular for rotator cuff repair. Preoperative evaluation of the bone 
      microstructure is of utmost importance because, especially in elderly patients, 
      osteoporotic changes may cause anchor pullout, which results in failure of 
      rotator cuff repair. Many groups have reported humeral microstructural analysis; 
      however, most studies were experiments using porcine specimens or human cadavers. 
      In this study, we used multidetector row computed tomography to successfully 
      perform in vivo evaluation of the bone microstructure of the humeral greater 
      tuberosity in patients with rotator cuff tears. METHODS: Ten patients were 
      examined. Regions of interest were defined in six quadrants of the greater 
      tuberosity (medial, lateral, and far lateral rows of the anterior and posterior 
      areas). The local bone mineral density and the trabecular microstructural 
      parameters, including the mean bone volume to total volume (BV/TV), trabecular 
      thickness, trabecular separation, and structure model index (SMI), were measured 
      using bone analysis software. RESULTS: The BV/TV of the posteromedial region was 
      highest and the SMI of the posteromedial region was lowest. These findings 
      suggest that the bone quality of the posteromedial portion is the highest within 
      the greater tuberosity. CONCLUSION: Because the bone quality may be correlated 
      with the pullout strength of suture anchors, our method can help to understand 
      the individual and regional variance in bone quality and may lead to the creation 
      of personalized surgical protocols.
