Abstract

Background: Comminuted fractures happen frequently due to traumas. Fixation without opening the fracture site,
known as minimally invasive plate osteosynthesis (MIPO), has recently become prevalent. This study has been
designed to assess the outcomes of this treatment for tibial and femoral comminuted fractures.
Methods: A total of 60 patients with comminuted femoral or tibial fractures were operated with MIPO method in this
cross-sectional study at Alzahra university hospital in 2015. Eleven patients were excluded due to lack of adequate
follow-ups. Patients’data including union time; infection in the fractured site; hip and knee range of motion; and any
malunion or deformities like limb length discrepancy were collected after the surgery in every session.
Results: Among 32 femoral and 17 tibial fractures, union was completed in48 patients, while only one patient with
femoral fracture had nonunion. The mean union time was 18.57±2.42 weeks. Femur fractures healed faster than tibia
(17.76±2.36 compared to 19±2.37 weeks, respectively, P=0.09). None of the patients suffered from infections or fistula.
The range of motion in hip and knee remained intact in approximately all patients. Malunion happened in 3 patients; 100
internal rotation in 1 patient; and 1cm limb shortening in 2 patients.
Conclusion: According to the result of this study, MIPO is a simple and effective method of fixation with a high rate
of union as well as minimal complications for comminuted fractures of long bones. Infection is rare, and malunion or
any deformity is infrequent. MIPO appears to be a promising and safe treatment alternative for comminuted fractures.
