Abstract

PURPOSE
This study compared the radiological and clinical results of minimally invasive plate osteosynthesis (MIPO) and intramedullary nailing (IMN) of distal tibial fractures, which were classified as the simple intra-articular group and extra-articular group.
MATERIALS AND METHODS
Fifty patients with distal tibial fractures, who could be followed-up more than 12 months, were evaluated. Group A consisted of 19 patients treated with MIPO and group B consisted of 31 patients treated with IMN. The results of each group were analyzed by radiological and clinical assessments.
RESULTS
The mean operation times in groups A and B were 72.4 minutes and 65.7 minutes, respectively. The mean bone union times in groups A and B were 16.4 weeks and 15.7 weeks, respectively. The bone union rate in groups A and B were 100% and 93%, respectively. The ranges of ankle motion were similar in the two groups at the last follow-up. The mean American Orthopaedic Foot and Ankle Society score was similar: 90.1 in group A and 90.5 in group B. The radiological and clinical results were similar in the intra and extra-articular groups. In groups A and B, two cases of posterior angulation and five cases of valgus deformity of more than 5° were encountered.
CONCLUSION
Both MIPO and IMN achieved satisfactory results in extra-articular AO type A and simple articular extension type C1 and C2 distal tibia fractures.
