Technical Trick: Coronoid Fracture “Lasso” Repair Using Arthroscopic Instrumentation in Terrible Triad Injuries With Fixable Radial Head Fractures

A single-stage operative repair of terrible triad injuries through a laterally-based approach using arthroscopic instrument-assisted reduction of the coronoid fracture in cases in which the radial head is deemed appropriate for repair rather than arthroplasty is described in this technical trick. Using an arthroscopic suture lasso, adjustable drill guides, cannulated guide-pins with nitinol shuttling wires, and a suspensory cortical button allow for a more precise and facile technique of "lasso" fixation of coronoid fractures and anterior capsular injuries with intact radial heads in terrible triad injuries.
