The most commonly injured nerve during the supracondylar fractures in children is controversially reported as the median nerve (% 28-60), followed by radial and ulnar nerves. The median nerve injury is usually seen in the fractures with posterolaterally displacement and the anterior interosseous branch (AIN) of this nerve is often injured. Here, we present a supracondylar humeral fracture of a 7 years old male child who had a neuropraxia postoperatively, which probably developed intraoperatively during the reposition of the median nerve which was migrated from anterior compartment to the posterior. Although the cause of the nerve stretching is reported to be fracture displacement in the literature, there is no report on stretching of median nerve by migrating to the posterior compartment. Neuropraxia of the AIN can occur in the situations where the median nerve is found to migrate from anterior to posterior compartment in the supracondylar humeral fractures of children. We believe that during the posterior surgical approach for the treatment of the supracondylar fractures of the humerus in children, the tissues over the periosteum must be bluntly dissected to avoid from an iatrogenic median nerve cut.
