Clinical analysis of two fixation methods for treatment of type C adult distal humerus fractures

Objective To compare and evaluate the curative effects of limited open reduction and internal fixation combined with external fixator and open reduction and internal fixation with AO two plates. Methods Fifty two cases of distal humerus type C fractures from Sports Hospital of Chengdu Sports University and Hospital of Traditional Chinese Medicine, affiliated to Luzhou Medical College were randomly assigned into two groups. Group A underwent open reduction and limited internal fixation combined with external fixator of distal radius bracket and group B were treated with internal fixation with two plates of the distal humerus. Results All patients were followed up for 12-36 months, an average of 27 months. In group A good rate of Cassebaum score was 81.5%, and in group B excellent and good rate was 52.0%, group A was significantly better than group B; Morry-Chao score in group A was an average of 87 points, group B for 84 points, the difference was not statistically significant. Conclusion Open reduction and limited internal fixation combined with external fixator for treatment of humeral distal type C fractures is better, and worthy of clinical application.
