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.
