II. Definitions
- Coronoid Process Fracture
- Proximal Ulna Fracture at the coronoid process
III. Physiology
- Coronoid process is the anterior projection of the olecranon that prevents posterior displacement of the elbow
IV. Epidemiology
- Rare Fracture that accompanies 10-15% of Elbow Dislocations
V. Imaging
-
Elbow XRay
- Best seen on lateral view
VI. Evaluation
- Arm neurovascular assessment
- Radial pulse at elbow at 90 degrees flexion
VII. Management
- Elbow Dislocation management
- Orthopedic Consultation in most cases
- Elbow Dislocation with persistent instability
- Coronoid Process Fracture with displacement
- Conservative management
- Long Arm Splint with elbow at 90 degrees flexion for up to 3 weeks
- Range of motion may be initiated after 1-3 weeks if repeat imaging shows no further displacement
- Indications
- Isolated Coronoid Process Fracture with no other associated injuries
- Fractures with <5 mm displacement
- Stable elbow
- Long Arm Splint with elbow at 90 degrees flexion for up to 3 weeks
