(A) Preoperative antero-posterior and lateral radiographs.
(B) Regan and Morrey type I coronoid fracture, type I radial head fracture was observed in computed tomography.
(C) Only lateral ulnar collateral ligament has been sutured with Mitek anchor and stability was achieved.
Fig. 3Postoperative anteroposterior and lateral radiographs show reduced joint with fixation of the coronoid process.

Fig. 5
(A) Subluxated radiocapitellar joint was observed despite manual reduction of terrible triad injury.
(B) Anteroposterior and lateral radiographs of an elbow fracture-dislocation that inadequately characterized the extent of bony injury. Three-dimensional computed tomography scan showing anteromedial facet fragment and olecrenon fragment.
(C) Locking plate and screws were used for fixation of coronoid fracture and olecrenon fragment.
Fig. 6Anteroposterior and lateral radiographs of an elbow fracture-dislocation that inadequately characterized the extent of bony injury. Three-dimensional computed tomography scans show the radial head fracture and associated comminuted proximal ulnar and coronoid fracture.
