BACKGROUND: Fractures of the distal tibia can be challenging to treat because of the limited soft tissue,
the subcutaneous location, and poor vascularity. There is a considerable debate regarding the best
method for treating distal tibial fractures. In present study we have treated distal tibial fractures using MIPPO technique
OBJECTIVES: To evaluate the functional outcome following use of MIPO technique in lower 1/3rd fractures of tibia.
MATERIAL AND METHODS: This is a longitudinal follow up study. In this study a total of 30 patients with fracture distal 1/3rd
tibia admitted to CMRI hospital will be selected for treatment with MIPO technique according to inclusion and exclusion criteria.
All patients were reviewed in CMRI Hospital and radiographs (Tibia AP and lateral views) obtained after surgery and then at 1
month, 3 months and nally at 6 months. From 5 weeks onwards symptoms and functions will be assessed using the scoring
system of Olerud and Molander(1984). Statistical analysis of categorical variables was expressed as number of patients and
percentage of patients and continuous variables are expressed as descriptive statistics. The statistical software SPSS version 20
has been used for the analysis.
RESULTS: The age of patients ranged from 22-65 years. Fracture was most common in 4th and 5th decade of life. Average mean
age was 44.03±10.74yrs. In this study majority of 17(56.7%) patients were male and there were 13(43.3%) were female. Road
Trafc accident (RTA) was the main cause to produce lower end tibia fractures (83.3%) in our study. In this study right side (60%)
was involved more than left (40%). In this study only 3 (10%) patients had open grade 1 injury. Majority of patients 27 (90%) had
closed injury. In our study 66.67% (20) of patients had associated injuries and 33.33% patients had no associated injury. Average
injury operation interval in this study was 3.27±1.53 days. Average no. of plate holes were 10.50±1.72. Average duration of
hospital stay in this study was 10.07±2.75 days. Average duration of surgery in this study was 88.03±16.36 minutes. In this study
26 patients (86.7%) had no early post-op complications and 4 (13.3%) had complications. 3 patients (10%) had delayed wound
healing and 1patient (3.3%) had supercial infection of suture lines. There was 1 non-union and majority of patients 21(70%)
took 20-25 weeks for union. 7(23.4%) patients took less than 20 weeks and 1(3.33%) patient took more than 25 weeks. Average
time of union in this study was 21.17±2.17 weeks. Average time of weight bearing was 17.72±1.91 weeks in this study. Most
frequent late complication seen was swelling with frequency of 7 followed by stiffness and pain. 1 patient had malunion and 1
patient had non-union. In this study there were 28(93.3%) patients which showed union, 1 (3.3%) patient showed coronal
malunion and 1(3.3%) had non-union. There were 21 patients (70 %) with excellent result, 7 patients (23.3%) with good result and
2 patients (6.7%) with fair result in our cases of study. Average clinical Olerud & Molander score was 81.17±16.07 in this study.
CONCLUSION: The satisfactory functional results and lack of soft tissue complications suggest that this method should be
considered in peri-articular fractures. Biological xation of complex fractures gives stable as well as optimal internal xation
and complete recovery of limb function at an early stage with minimal risk of complications.
