title: [Surgical treatment for Mayo II B comminuted fracture of the olecranon].
abstract: OBJECTIVE
  To study clinical effects of surgery for the treatment of Mayo II B comminuted fracture in ulna olecranon.
  
  
  METHODS
  From May 2008 to March 2015, a total of 37 patients with Mayo II B comminuted fracture in ulua olecranon were treated, including 20 males and 17 females, ranging in age from 40 to 65 years old ,with an average of 53 years old. All the patients were treated with open reduction and internal fixation within 4 to 7 days after injuries. All the patients had pain and functional disorder uf elbow joint. The X-ray and CT examination showed ulna olecranon comminuted fracture of Mayo II B. Postoperative complications were observed ,and Broberg-Morrey criteria was used tu evaluate therapeutic effects.
  
  
  RESULTS
  All the patients were followed up ,and the duraiton ranged from 9 to 30 months ,with a mean of 15 months. Two patients had surface infection around incision ,and were healed by changing dressings. No other complications occurred such as needle slipping to stimulate skin ,screw loosening and wire broken. One patient had slight uneveness of joint surface without obvious functional disorder. According to Broberg-Morrey elbow fracture curative effect criteria, 11 paients got an excellent result, 24 good and 2 fair,and the total score was 87.0 ± 7.3.
  
  
  CONCLUSIONS
  For the Mayo II B comminuted fracture in ulna olecranon, preoperative preparation, intraoperative restoring of the articular surface smooth and reasonable internal fixation, and postoperative rehabilitation actively, can obtain satisfactory clinical effects.
