Coronoid Process Fracture

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