title: Isolated shear fracture of the humeral trochlea in an adolescent: a case report and literature review.
abstract: This report documents a rare case of isolated trochlear shear fracture in an adolescent patient and provides a literature review. Radiographic analysis of the distal humerus revealed an intra-articular fracture of the anterior trochlea, evidenced by a full moon-shaped osteochondral fragment. Open reduction and internal fixation with two headless Herbert screws secured the fragment. Because of the paucity of information on this injury, standard treatment and management have not been established. Prospective studies with longer follow-up are needed before a consensus with regard to these fractures is established.
