Abstract

PURPOSE: To evaluate the advantages of fixation of metaphysis by minimally invasive plate osteosynthesis(MIPO) technique for comminuted fractures of the proximal tibia. MATERIALS & METHODS: from January 1997 to February 2000, 18 cases of comminuted fracture of the proximal tibia were treated using MIPO technique. Operation time, union time, radiologic alignment, range of motion of the knee joint, functional and anatomical results according to Rassmusen's grading criteria, complications were evaluated. Minimal follow-up time was 12 months.
RESULTS
Operation time was average 51 minutes (30-80 minutes). Time to bone healing was average 10.6 weeks (9-14 weeks) There was 1 case of valgus angular deformity greater than 5 degrees. 6 cases in acceptable bony alignment less than valgus 5 degrees and 11 cases were classified into normal bony alignment. Range of motion of the knee joint was 0-140 degrees in 13 cases, 0-120 degrees in 3 cases, 0-90 degrees in 1 case, 10-90 degrees in 1 case. Rasmussen's grading criteria for functional outcome revealed there were 14 cases(77.8%) excellent results, 4 cases(22.2%) good result. and grading criteria for anatomical outcome revealed there were 7 cases(38.9%) excellent results, 11 cases(61.1%) good result.
CONCLUSION
MIPO technique for comminuted fracture of the proximal tibia seems to be a good techinque to obtain more rapid bony union with less complication.
