SURGICAL TREATMENT BY PEDICLE FLAP TRANSFER FOR GUSTILO TYPE III B OPEN FRACTURE OF THE TIBIA WITH SOFT TISSUE DEFECT

Abstract

　　Objectives : To examine the clinical and preoperative evaluation results of treating Gustilo type III B open fractures of the tibia with soft tissue defects by the pedicle flap transfer method. Materials and Methods : Between 2011 and 2015, 8 cases of tibia fracture with soft tissue defects in 7 males and 1 female aged 20-72 years were treated at our institution. We evaluated each case using the AO soft-tissue grading system and Ganga Hospital Scoring System (GHS), which are specifically designed to evaluate III B injuries. Results : According to the AO soft-tissue grading system, 1 case was MT1, 5 cases were MT2, and 2 cases were MT3. On the scoring of functional tissues by musculotendinous (MT) and nerve units based on the GHS, 1 case had a score of 1, 5 cases had a score of 2, and 2 cases had a score of 3. Two flaps that were MT3 with a score of 3 were lost to necrosis. Conclusion : Pedicle flap transfers can be performed for Gustilo type III B tibia fractures that have an AO soft-tissue grading system score up to MT2 and GHS musculotendinous functional tissues score up to 2.
