Objective To explore feasibility and clinic results of the MIPPO (minimally invasive percutaneous plate osteosynthesis) technique in treatment of humeral fractures. Methods 14 patients with humeral fracture underwent the MIPPO operation in our department. 7 of them were injured in a traffic accident, 4 in sports and 3 in daily life. There were 11 males and 3 females, with their ages ranging from 16 to 72 years. Of the 14 cases, 9 were proximal ones and 5 mid- distal ones, 3 were multiple injuries and 1 pathological fracture. Results The average intra- operative time was 80 minutes (ranging from 55 to 130 minutes). No patient received blood transfusion. The intra- operative blood loss was 100 to 200 mL. 14 cases were followed up for 8 weeks to 14 months. Their cuts healed at the primary stage. Their shoulder and elbow functions were fine. The fracture segments got satisfactory reduction with good apposition and alignment radiologically. The callus appeared 4 to 8 weeks postoperatively. Conclusion MIPPO is a safe and effective treatment for the humeral fracture with the benefits of less invasion, fewer complications and higher union rate.
