Abstract
INTRODUCTION: Traditional open reduction and internal fixation (ORIF) of extra-articular distal humerus fractures has a risk of iatrogenic radial nerve injury, extensive soft tissue stripping, and long incision scar. We performed an antero-lateral minimally invasive plate osteosynthesis (MIPO) technique with the radial nerve exploration for distal-third diaphyseal fractures of the humerus and evaluated clinical and radiographic outcomes through this respective study. METHODS: From April 2010 to June 2016, 28 cases of extra-articular distal-third diaphyseal fractures were treated with an antero-lateral MIPO procedure. Patient demographics, Disabilities of the Arm, Shoulder and Hand (DASH) Score, Mayo Elbow Performance (MEP) Score, elbow range of motion, scars and post-operative complications were recorded and analyzed. RESULTS: All fractures were united with a mean time of 3.5 months. One patient exhibited delayed union (3.6%). The mean DASH Score was 6.6, and all patients had excellent or good MEP Score values. The average scar length was 6.8 cm, and the shortest was 4.5 cm. CONCLUSIONS: The MIPO technique via an antero-lateral approach for extra-articular distal-third diaphyseal fractures of the humerus results in satisfactory clinical outcomes. LEVEL OF EVIDENCE: Level IV, case series, treatment study.
