Effects of dual-plate fixation for intercondylar fracture of the humerus via triceps muscle

Objective: To explore the effects of dual-plate fixation for intercondylar fracture of the humerus via triceps muscle.Methods: Forty-two intercondylar fracture cases the collected during January 2007 and January 2011 underwent dual-plate fixation via triceps muscle(n=21,observation group),and Y-shape plate fixation(n=21,control group).Elbow joint function,complication incidence,fixation stability and elbow mobility were observed and compare between the two groups.Results: Following up ranging from 3 months to 4 years showed that 13 of the 19 cases of the observation showed excellent outcomes,3 showed good outcomes with and excellent rate of 84.2%,for 20 cases of the control group,the corresponding number was 9 and 5,excellent rate was 70.0%,showing significant difference between the two groups(P0.05).Neither fixation failure nor complications were observed in the observation group,while fixation failure and complications were observed in 15.0% and 5.0% of the 20 cases,which was significant higher than the observation group(P0.05).Mobility of the involved elbow for the observation group was(126.4°±14.2°) significant higher than(103.4°±5.2°) of the control group.Conclusions: Dual-plate fixation via triceps muscle is an effective treatment for intercondylar fracture of the humerus.
