Background
- Salter-Harris type IV fracture
- Neurovascular injury uncommon
Humerus Fracture Types
Clinical Features
- Swelling and tenderness limited to lateral elbow
- neurovascular injury is uncommon
Differential Diagnosis
Elbow Diagnoses
Radiograph-Positive
- Distal humerus fracture
- Radial head fracture
- Capitellum fracture
- Olecranon fracture
- Elbow dislocation
Radiograph-Negative
- Biceps tendon rupture/dislocation
- Lateral epicondylitis
- Medial epicondylitis
- Olecranon bursitis (nonseptic)
- Pronator teres syndrome
- Septic bursitis
Pediatric
- Nursemaid's elbow
- Supracondylar fracture
- Lateral epicondyle fracture
- Medial epicondyle fracture
- Olecranon fracture
- Radial head fracture
- Salter-Harris fractures
Evaluation
- Xray
- Obtain oblique view if suspicion high despite neg AP/lat
- Radiocapitellar line will not intersect middle of capitellum in all views
- May be only sign of fracture if fracture is entirely through growth plate
- +Fat Pad Sign/"sail" sign
- May be only sign of nondisplaced fracture
Management
General Fracture Management
- Acute pain management
- Open fractures require immediate IV antibiotics and urgent surgical washout
- Neurovascular compromise from fracture requires emergent reduction and/or orthopedic intervention
- Consider risk for compartment syndrome
Specific Management
- Often requires ORIF (ortho consult)
