Yoo, Kang, and Seo: Surgical Results of Minimally Invasive Percutaneous Plate Fixation in the Treatment of Clavicle Shaft Fracture

Abstract

Purpose

This study analyzed the results of the midclavicle fracture treatment using the minimally invasive percutaneous plate osteosynthesis (MIPO) technique in a retrospective manner.

Materials and Methods

Between March 2013 and March 2017, this study analyzed 40 patients who received MIPO surgery. Excluding 1 patient who underwent surgery on another body part injury, and 4 patients who were lost to follow-up over 1 year, 40 patients were analyzed for their operation time, bone union, functional American Shoulder and Elbow Surgeons score, scar lengths, pain relief (visual analogue scale), and complications.

Results

All patients over a 1 year of follow-up achieved bone union, and American Shoulder and Elbow Surgeons score 97.6 (94–100) on their shoulder functional scores. Their average operation time was 42.7 minutes, and the average scar length was 6.1 cm. Eighteen patients successfully received metal removal using the previous scar without additional incision. The clavicle length was similar in the normal and operated group.

Conclusion

Despite its small sample size, clavicle fixation using the MIPO technique can be considered an effective treatment because of its limited number of complications, such as nonunion and rotational angulations.
