Coronoid Fractures of the Elbow

Evaluation and Treatment of the Elbow and Forearm Injuries in the Emergency Department

“…These fractures occur most frequently in association with other injuries, such as elbow dislocations, and a coronoid fracture should suggest the need to look for other signs of injury to the joint. 44 They are a result of shear forces of the distal humerus on the coronoid Treatment of the Elbow and Forearm Injuries process. 45 The Regan and Morrey classification system describes fractures in 3 categories 46 :…”

The Comparative Stability of Screw Versus Plate Versus Screw and Plate Coronoid Fixation

“…2,6 In large coronoid fractures, this anterior buttress is completely disrupted. 2 Restoration of the coronoid's anterior buttress is critical to future elbow stability. 6 Small coronoid tip fractures (O'Driscoll type 1) are associated with terrible triad injuries.…”

“…9 Historic recommendations are to fix all large coronoid fracture fragments as well as small fracture fragments associated with instability. 2 A previous biomechanical study has shown that 50% of the coronoid process must be intact to minimize axial displacement of the ulnohumeral joint, and that posterior axial displacement was significantly increased if more than 50% of the coronoid was removed. 10 Based on biomechanical investigations, many authors have recommended that all type 3 fractures (Ͼ50% of the coronoid's height) should be fixed in addition to addressing any associated fractures and ligament injuries.…”

“…[1][2][3][4][5] One major mechanism for coronoid fractures is a posterior axial load, which creates a shear force concentrated on the articular surface of the coronoid process. 2,6 In large coronoid fractures, this anterior buttress is completely disrupted. 2 Restoration of the coronoid's anterior buttress is critical to future elbow stability.…”

Surgical Outcomes after Olecranon Plating with Retrograde Coronoid Process Screw Fixation through the Plate Hole in the Bifocal Fracture of the Proximal Ulna

“…4,5) 더하여 관절 강직의 예방을 위한 조기 능 동관절운동 역시 필수적이다. [6][7][8] 이러한 After fixation of the olecranon, the gap of the coronoid process fragment was checked with using an image intensifier. In cases of more than 2 mm of gap, the coronoid process was indirectly reduced with using a bone hook and provisional fixation with K-wire was performed done.…”
