Minimally Invasive Plate Osteosynthesis for Distal Tibial Metaphyseal Fracture

ABSTRACT

PURPOSE: To retrospectively reviewed the outcomes and advantages of minimally invasive plate osteosynthesis (MIPO) technique as a new treatment of distal tibial metaphyseal fracture. MATERIALS AND METHODS: Nineteen distal tibial metaphyseal fractures were treated by MIPO technique and evaluated radiologically and functionally. A mean age was 46 years old (range 20~69 years) and a mean follow-up was 15 months (range 6~37 months). Sixteen fractures were not extended into ankle joint (AO/OTA type A1;4, A2;8, A3;4) and three fractures were extended into ankle joint (AO/OTA type C1;2, C2;1). Two cases were open fractures (type I;1, type III-A;1) according to the Gustilo-Anderson classification. RESULT: At a mean of 18 weeks (range 12 to 24), all fractures united without secondary procedures. A mean score was 94.2 point by Baird ankle scoring system. There were no complications including shortening over 1 cm, mal-alignment over 5 degrees, deep infection, or implant failure. CONCLUSION: MIPO technique of distal tibial metaphyseal fracture is a worthwhile method with good unions and functional recovery.
