Objective To compare the efficacy of four internal fixation method for the treatment of distal humerus fractures . In June 2009 to December 2010 , our hospital treated 36 cases of distal humerus fracture patients . Male patients in 23 cases, 13 cases of female patients , aged between 16 to 61 years old , the average age of 36 patients by AO / ASIF classification criteria after typing fracture type is A - 6 , are B-type 12 cases, 18 cases of C - type . In all cases , the use of Kirschner wire fixation of the three cases , the use of a single plate 13 cases , 10 cases fixed by bilateral reconstruction plate , Y plate 10 cases . For this group of patients surgical approach , internal fixation and postoperative joint function recovery were analyzed . The results were followed up for 6 to 17 months , an average of 9 months , fracture healing is generally about 10 to 16 weeks , the average healing time of 14 weeks , all cases of postoperative wound infection , 1 case of fracture healing , 1 case of trauma myositis ossificans . Kirschner and bilateral reconstruction plate without loosening fracture , and the Y- plate and single- plate cases were broken . After the elbow Cassebaum scoring system , excellent in 17 cases : elbow 15 °, 130 ° elbow elbow asymptomatic . Good in 10 cases : elbow 30 ° elbow 120 ° elbow or no symptoms . 6 cases : stretch elbow 40 degrees , 90 ° to 120 ° elbow ; elbow symptoms . Poor in 3 cases : extension elbow 40 ° elbow lt ; 90 ° , excellent rate of 75.0% . Conclusion by selecting the appropriate surgical approach and internal fixation can effectively improve the therapeutic effect of distal humerus fractures . In addition, the earlier after reasonable joint function recovery exercise is also an important factor to affect the distal humerus fracture healing . Comparison , analysis and efficacy of the olecranon osteotomy way better than the other approach , because it can fully exposed distal humeral articular surface , especially for the treatment of C-type C3 fractures , have a special advantage . Can effectively avoid the triceps injury , and allow early postoperative exercise , stand joint and muscle function recovery . Four internal fixation , bilateral reconstruction plate fixed effect is excellent, due to its fixation conducive to fracture healing , reducing the incidence of postoperative complications , conducive to the early recovery of the function of the elbow .
