Outcome of Mini mally Invasive Plate Osteosynthesis (MIPO) in the Treatment of Multifragmentary Fractures of Tibia at Lumphun Hospital

Abstract

           Common complications in the treatment of mulifragmentary fractures of tibia by fixation with conventional plate and screws are delayed union, nonunion and infection. Minimally invasive plate osteosynthesis MIPO technique was introduced to reduce these complication’s. This retrospective comparative study objected to compare the outcome of treatment between conventional plating technique and MIPO at Lumphun hospital in 74 patients with multifragmentary fractures of tibia during 1 June 2005-31 December 2008. All patients are aged during 12-17 years (average 28.9years). Most common causes of fractures is from traffic accidents(81.6%). 38patients were treated with conventional plating technique and 36 patients were treated with MIPO technique. The results of treatment were measured by time to radiographic union, time to full weight bearing and rates of complications. Chi-square tests was used for statistically comparative study. The outcomes were MIPO group have lower time to union(p0.017) lower time to full weight bearing (p0.001) and lower risks of infection(0.015) significantly when compare with standard plating technique.
