Use of Mother-Child Screws in the Treatment of Coronoid Fractures in Terrible Triad Injury of the Elbow

of coronoid fractures, including plates, lag screws, suture anchors, or suture lasso techniques (4,7,13,27).However, coronoid fracture fragments are frequently small, and makes reliable internal fixation difficult (12,18,25).The best surgical protocol to treat coronoid fractures in terrible triad injuries remains unclear.This study enrolled 18 patients with terrible triad injuries, and the outcome of a modified protocol for the treatment of coronoid fragments using MCS was explored (Fig. 1), which consists of two parts of child-screws (Fig. 1, arrow A) and the mother-screw (Fig. 1, arrow C).
