We cannot recommend for or against using an open incision to introduce a medial pin to stabilize the reduction of displaced pediatric supracondylar fractures of the humerus.

Therefore the group deemed it important to examine the technique of medial pin placement; specifically if there was a difference in ulnar nerve injury rates related to percutaneous vs. open medial pin placement. There was no existing adequate data to address the technique of medial pin placement.
