Abstract: Background: Reconstruction plates have been used from a long time for fixation of distal humerus fractures. Locking plates are increasingly used now-a-days. The aim of this study is to compare the radiological and functional outcome of AO Type C distal humerus fracture treated with pre-contoured locking plates and conventional reconstruction plates.
Material and Methods: A total of 25 patients of AO type C distal humerus fracture were enrolled for the study during 2016- 2018. Out of 25 patients, 14 were treated using locking plates and 11 were treated using reconstruction plates. Patients were followed up at 2 weeks, 6 weeks, 3 months, 6 months and 12 months post operatively. Radiological assessment was done by follow-up X-rays at 3, 6 and 12 months. Mayo Elbow Performance Score was used for assessment of functional outcome at 3, 6 and 12 months post-operatively.
Results: The mean duration of surgery and hospital stay was similar in both the groups. The mean Range of motion and MEPS score was significantly higher in locking plate group as compared to conventional reconstruction plates at 3 months post operatively. However both of them were similar at 6 months and 12 months post operatively. 93% union rate in locking plate group and 9% union rate in reconstruction plate group were seen at the end of 12 months follow-up. Excellent and/or good results were obtained in 93% in locking plate group which is significantly higher than reconstruction plate group in which only 82% patients had excellent and/ or good results.
Conclusion: Locking plates has advantage over reconstruction plates in early mobility and greater functional outcome.
