Abstract:

Objective To investigate the clinical effect of digital measurement based on the relative height of humeral head in the treatment of acromion impingement syndrome. Methods From February 2014 to March 2016, 89 patients with impingement syndrome were admitted. The relative height of the humeral head was measured by CT before the operation, andwe used C-type-arm to determine grinding position during the operation.We compared CT data,CMS andVAS between preoperation and postoperation to evaluate the clinical efficacy. Results  During an average follow-up of 15.5 months,88 patients were followed-up. At the last follow-up, all patients’ shoulder function has fully recovered. The relative height of humeral head was increased from (0.73±0.15) cm to (1.08±0.08) cm (P<0.05). The CMS was increased from (46.7±3.99) to (91.8±2.32) (P<0.05),and the VAS decreased from (5.3±1.1) to (0.6±0.3) (P<0.05). Conclusion The clinical efficacy of arthroscopic greater tuberosity plasty based on digital measurement of the relative height of humeral head for the treatment of acromion impingement syndrome was reliable.
