Functional outcome of distal end femur fractures treated by minimally invasive plate osteo-synthesis using locking compression plate: a prospective study in 50 adults
Background: Distal femoral locking compression plate can be done via minimal invasive methods, overcoming the drawbacks of excessive stripping as caused by open methods. Fixed locking construct of the plate also provides stable fixation needed for early mobilization in fractures of distal femur. Hence, we evaluated the results of distal femoral locking compression plate done via minimally invasive technique in fractures of distal end femur.
Material and methods: 50 cases of fracture distal end femur were treated by internal fixation with distal femoral locking compression plate via minimal invasive techniques and were evaluated radiologically for union and functionally, using NEER’S Score.
Results: 50 distal end femoral fractures (29 males and 21 females) with mean age of 51 years (range 20 to 83 years) were included in study. Mean duration for surgery was 67 minutes (range 60 to 89 minutes), mean blood loss was 119 ml (range 100 to 140 ml) and mean union time was 14.3 weeks (range 11 to 20 weeks). 38 (76 %) patients had excellent results and 8 (16%) had satisfactory results as per NEER’s scoring system with mean NEER’s score of 90.133 (range 74 to 96). Complications seen were knee stiffness as seen in 4 (8%) cases, 4(8%) had superficial infection, 1 (2%) had implant failure, 2 (4%) had malalignment and 1(2%) had nonunion.
Conclusion: Pre-contoured distal femoral locking compression plate by virtue of its features, to provide stable fixation and done via minimal invasive technique, provides excellent function, high rate of bone union and fewer complications, even in severely comminuted fractures and osteoporotic bones of distal end femur.
