Functional Outcome Of OTA Type-C Distal Femur Fracture Fixed With Locking Compression Plate

Abstract

Background:A distal femur fracture is a very complex injury constituting about seven percent of all femur fractures and a huge surgical challenge to restore function. The aim of this study is to access the functional outcome and the complication of distal Orthopaedic Trauma Association type C femur fracture using a locking compression plate.Material and Methods:A total of 35 cases was recruited as per inclusion and exclusion criteria. All the distal femoral fractures were treated with a distal femoral locking compression plate. The patients were followed up at 1, 3, 6, and 12 months respectively. There were 27 males and 8 females with a mean age of 48.5 years (range 25–94). The greater part of the cases was of type C2 (AO classification) and was due to high energy trauma. The functional outcome was assessed using the NEER’s criteria. Results:In this study, the average time of the union of fracture was 16 weeks (14-22weeks). In 26 cases (75%) we obtained satisfactory to excellent results. Post-operative complications associated with the fracture were knee stiffness six (17.1%), varus deformity in three (8.5%), shortening in five (14.2%), and two (5.7%) superficial wound infections. Conclusion:LCP plate is an effective method in distal femur fractures. It gives excellent stability and helps to maintain the length and alignment of the limb preventing metaphyseal collapse. It is also effective in osteoporotic fractures and reduces compression of periosteal vessels.
