Values are presented as mean (range).
Chi-square test for subjective satisfaction about surgical scar; independent t-test for the rest.
IM: intramedullary, MIPO: minimally invasive plate osteosynthesis, ROM: range of motion, AOFAS: American Orthopaedic Foot and Ankle Society.
*Subjective satisfaction about surgical scar: ratio of (highly satisfied+ satisfied)/ (highly satisfied, satisfied, acceptable, dissatisfied).
