Regeneration of Bone after Loss of the Distal Half of the Humerus: Case Report with a 20-Year Follow-Up

Abstract

A 16-year-old boy was involved in an agricultural accident in which he sustained a large wound to the right arm and forearm. Radiological examination showed loss of the distal half of the humerus. A posterior splint was applied and after two months there was regeneration of the distal humerus including the articular portion. He was able to use his arm at five months. Twenty years later, he had a painless elbow and a 70 degrees range of movement.
