Functonal outcome of ORIF of distal femur fracture(AO TYPE B) with intra-articular extension

Abstract

Background: Distal femur fractures with intra-articular extension (AO TYPE B) are complex injuries which have been treated by different methods. The authors studied the functional outcome of management of distal femur fractures with the published literature. Aim and objectives: The purpose of this study is to evaluate the outcome of operated cases of distal femur fracture with intra-articular (AO TYPE B) with open reduction and internal fixation and also to study union rates, full weight bearing of it by fixation. Study design: Retrospective study Materials and methods : Distal femur fractures with intra-articular extension (AO TYPE B) treated with open reduction and internal fixation during the period Jan 2011-Dec 2012 at Govt. Medical College, Surat formed the study population. They were evaluated to assess their clinical and functional results using Neers Scoring system and compared with the available literature. The results were analysed using different parameters; male vs. female, age distribution, functional outcomes and complications etc. Results: The results were excellent in 70%, good in 19%, fair in 11% and poor in 0%. Results were assessed and found to be excellent in majority of cases with mean knee flexion being 102.8 degrees, mean fracture union time of 15.5 weeks, with mean full weight bearing duration of 12.7 weeks .complications being knee stiffness (0),delayed union (01),infection (01),shortening(01)knee pain (04) Conclusion: Surgery in the form of ORIF is recommended for Distal femur fractures with intra-articular extension (AO TYPE B) for good outcome and early mobilization with minimum preventable complications.
