AO double plate for treatment of intercondylar fractures of the humerus via triceps-splitting approach

Objective To explore the surgical management and its effect of AO double plate in treating intercondylar fractures through triceps-splitting approach.Methods From Jul.2004 to Mar.2009,25 patients of intercondylar fracture of humerus were treated with AO double plate internal fixaton through triceps-splitting approach.There were 16 males and 9 females,with a mean age of 41.6 years(range 18-65 years).According to AO/ASIF classification,there were 7 cases of type C1,12 cases of type C2,6 cases of type C3.Results Satisfactory reduction was achieved in 24 cases,poor reduction in 1 case.No incision infection was observed.Ulnar nerve injury was observed intraoperatively in 2 cases.Twenty-one patients were followed up for 9-36 months(average 22.3 months).Of the 21 patients,all fractures healed,injured ulnar nerve recovered.There was no loosening and breakage.The healing time was 14-24 weeks,averaging 17 weeks.The function of the elbow(according to Cassebaum scale) showed excellent in 5 cases,good in 12,fair in 4 and poor in 1.The excellent and good rate was 80.9%.Conclusion The technique of AO double plate for treating intercondylar fracture of humerus through triceps-splitting approach has advantages of good anatomical reduction,stable fixation and early functional exercise.
