Pediatric Lateral Humeral Condyle Fractures

Abstract

Lateral humeral condyle fractures are common and potentially challenging injuries to treat.  Multiple classification systems have been proposed with the Weiss and Song classifications helpful for treatment and prognosis.  Nonsurgical management is the mainstay of nondisplaced or minimally (<2mm) displaced fractures, though vigilance in ensuring lack of displacement during treatment is mandatory.  Surgical management is performed with closed or open reduction, depending on the amount of displacement and the need to visualize the articular surface for an anatomic reduction.  Kirschner wires or screws are both appropriate methods of fixation.  Delayed union and nonunion can occur, though with appropriate vigilance and early surgical treatment, chronic nonunion can be avoided.  If nonunion can be avoided, most patients are expected to have excellent functional results after treatment of pediatric lateral humeral condyle fractures.  Stiffness, and lateral bump formation are common complications, though may not lead to major functional disability.
