Abstract

PURPOSE
In this study we introduced minimal invasive plate osteosynthesis (MIPO) and analyzed clinical outcomes to determine the effectiveness of this intervention in proximal humerus fractures.
MATERIALS AND METHODS
We studied 27 patients including 16 cases with a 2-part fracture, 10 cases with a 3-part fracture, and 1 case with a 4-part fracture. Clinical outcomes were evaluated using UCLA score, KSS score and recovery of range of motion. Time to union and humerus neck-shaft angle change were estimated by radiologic assessment. The average follow up period was 19 months.
RESULTS
UCLA scores were "excellent" for 15 patients, "good" for 12 patients. The mean KSS score was 91.4 at final follow-up. The average shoulder range of motion was 167.2degrees in forward elevation. Bone union occurred by 14.1 weeks postoperatively. Humerus neck-shaft angle recovery was "excellent" in 24 patients and "moderate" in 3 patients. There were no complications such as axillary nerve paralysis, deep infection, or subacromial impingement of the plate.
CONCLUSION
MIPO for proximal humerus fractures is an effective procedure if performed with sufficient understanding of the anatomical structures. MIPO leads to minimized dissection of soft tissue, low complication rates and early recovery of range of motion.
