The triceps tongue-shaped flap approach double-plate fixation for 34 cases of AO C_3 type intercondylar fracture of humerus

Objective The purpose of this study was to determine the outcome of treating complex distal humeral fractures (AO C3) with double-plate fixation through triceps tongue-shaped flap approuch.Methods Thirty-four consecutive complex distal humeral fractures (AO C3) were fixed with two parallel plates (medially and laterally) applied in approximately the sagittal plane through triceps tongue-shaped flap approach.The patients were assessed clinically with use of the Mayo Elbow Performance Score (MEPS) and radiographically.Results 32 cases remained good reduction without infection.32 of 34 cases were followed for 6 to 19 months,an average of 13.5 months.Neither hardware failure nor fracture displacement occurred in any patient.Elbow pain was not occurred.The mean flexion-extension arc was 92° (88°～107°),and the mean MEPS was 84.5 points.Healing time was 14 to 24 weeks,17 weeks on average.The result was graded as excellent for ten elbows,good for nineteen,fair for four,and poor for one.Excellent rate was 85.29%.Conclusion Stable fixation and a high rate of union of complex distal humeral fractures can be achieved with double-plate fixation through triceps tongue-shaped flap approach.Elbow functional activity can be achieved in patients with early stage.
