Abstract

Abstract : Case: We describe a patient with incomplete high median nerve palsy after surgical treatment of pediatric supracondylar humeral fracture (SCHF). Preoperative images after 11 months after the surgical treatment of the SCHF showed rotational deformity and an isolated median nerve entrapped between the proximal humerus anteriorly and callus posteriorly in the bony tunnel of the distal humerus. Two years after neurolysis, he showed clinical recovery. Four cases similar to our case were reported previously. Conclusion: Common pediatric fractures may cause unusual neuropathy. Rotational deformity of fracture might be an important factor for isolated median nerve entrapment after SCHF.
