Background:
Metaphyseal fracture of distal femur and proximal tibia results from high-velocity road traffic accidents. Using minimally invasive plate osteosynthesis (MIPO), the complex fracture zone is left untouched and length, alignment, and rotation are restored. As the fracture site is not explored, the osteogenic tissues surrounding the fracture are well protected and their blood supply is well preserved. This accelerates fracture healing.
Materials and Methods:
Thirty-five patients within the span of 3 years underwent internal fixation of distal end femur and proximal tibia by locking compression plate (LCP) using MIPPO technique. All the patients were assessed using Johner–Wruhs’ criteria and lower extremity functional scale (LEFS).
Results:
The mean time of partial weight bearing in fractures of distal femur was 10.14 weeks and proximal tibia was 9.71 weeks, respectively. The mean time of full weight bearing in fractures of distal femur was 16 weeks and in proximal tibia was 15.28 weeks. The mean time of bone union in fractures of distal femur was 18.14 weeks and in proximal tibia it was 18.57 weeks. The overall average LEFS score comes out to be 67 out of 80 points. According to Johner Wruhs’ criteria, results were excellent in 14 (40%), good in 16 (45.7%), fair in 4 (11.4%), and poor in 1 patient.
Conclusion:
MIPO techniques represent a fascinating new armamentarium in fracture fixation, which is made easier with the LCP technology and the different available minimally invasive surgical instruments, which were developed to cause less additional damage to the soft tissue and the bone.
