A COMPARATIVE STUDY OF FUNCTIONAL AND RADIOLOGICAL OUTCOME OF HIGH ENERGY PROXIMAL TIBIA FRACTURE USING ILLIZAROV EXTERNAL FIXATOR VS HYBRID EXTERNAL FIXATOR

Abstract

Background: In High energy proximal tibia fracture aim is to achieve adequate reduction and stability without signicantly compromising the soft tissue integrity and vascularity . External xator minimizes soft tissue dissection and minimize other complications. Method: 60 patients' high energy proximal tibia fracture with cases were considered in the study. 30 patients were treated with Ilizarov external xator and 30 patients were treated with hybrid external xator. Results were analyzed both clinically and radiologically using Johner and Wruh's criteria. Results: Mean time of union was 22 week in ilizarov xator group and 34 week in hybrid xator group. Pin tract infection occured in 6 patient (20%) in ilizarov xator group and 4 patient in hybrid xator group. Joint stiffness occured in 3 Patient (10 %) in ilizarov group and 10 patient in hybrid xator group.Shortning occured in 2 patient (6.6 %) in ilizarov xator group and 2 patient in hybrid xator group. Overal results in ilizarov group were excellent in 23 patient (76.7%), good in 5 patient (16.67%) , fair in 2 patient (6.67%) while in hybrid group excellent in 16 patient( 53.33%),good in 10 patient(33.33%),fair in 4(13.33%)patient. Conclusion: External xators are excellent modalities in treatment of high energy proximal tibia fracture with ilizarov method has advantage of early mobilization and early union but require long operative time and bulky framework on other hand hybrid xator has simpler construct ,lesser operative time but has lesser stability , longer union time and longer immobilization time.
