title: Clinical and radiologic outcomes of arthroscopic suture bridge repair for the greater tuberosity fractures of the proximal humerus.
abstract: OBJECTIVE
  To report the clinical and radiological outcomes of arthroscopic suture bridge repair for the GT fractures of the shoulder joint.
  
  
  METHODS
  From March 2008 to July 2013, we performed arthroscopic suture bridge repair of the GT fractures displaced more than 5 mm superiorly or posteriorly, but less than 2 cm in 40 cases [20 men, 20 women; mean age, 56 (27-80) years] with the average 32 (24-48) months follow-up. At the final follow-up, clinical (ASES, UCLA, SST, KSS score and range of motions) and radiological outcomes using post-operative MRI or CT scan were evaluated. Associated injuries occurred in 21 cases (52.5%): 8 rotator cuff tears; 7 SLAP lesions; 3 glenoid rim fractures; 3 Bankart lesions; 5 biceps tendon tears; 1 partial subscapularis tear; 1 combined subscapularis and biceps tendon tear, and 1 brachial plexus injury.
  
  
  RESULTS
  At the final follow-up, the mean VAS score improved from 7 to 1; ASES, to 92; UCLA, to 32; KSS, to 90; and SST, to 10. Mean forward flexion, abduction, external rotation at the side, and internal rotation at the back were improved to 157°, 157°, 37° and T11, respectively. Mean residual superior and posterior displacement of the fracture was 0 (range -5 to 3.3) mm and 0.1 (-5.5 to 3.2) mm, respectively, compared to pre-operative displacement of 4.9 (0-14) mm and 4.5 (0-20) mm, respectively (p < 0.001). Complications included anchor protrusion in five cases.
  
  
  CONCLUSIONS
  Arthroscopic suture bridge repair was useful for the treatment of displaced GT fractures with or without comminution and the management of the combined lesions. At the final follow-up, meaningful remodeling of the GT fracture and satisfactory clinical outcomes could be achieved.
