Anterior interosseous-nerve paralysis as a complication of supracondylar fractures of the humerus in children

Abstract

Two cases of anterior interosseous nerve syndromes following supracondylar fractures of the humerus in children are reported. In both cases spontaneous recovery began at 8 weeks and was complete at 10 weeks. The syndrome is discussed and the literature reviewed.

Surgical treatment and outcomes in 15 patients with anterior interosseous nerve entrapments and injuries

“…Anterior interosseous nerve paralysis as a complication of supracondylar fractures of the humerus in children has been described in several studies. [3][4][5]8,10,11,15,16,20,21,34 Fascicular torsion of the AIN in three patients with nontraumatic AIN palsy was described by Yasunaga, et al 39 Each of the three patients had an AIN that intraoperatively showed hourglass-like constrictions and 30˚ of fascicular torsion. These abnormalities were believed to have been formed on branching of the AIN from the median nerve.…”
