II. Epidemiology
- Uncommon condition in children
- Differentiate from Nursemaid's Elbow (subluxed elbow)
- Nursemaid's Elbow is much more common in children
III. Causes
-
Traumatic Injury dislocates radial head anteriorly
- Fall on an outstretched pronated arm
- "Bent Ulna" suggests Monteggia Fracture
- Congenital disorder
- Radial head dislocates posteriorly
- Radial Head Dislocation is often bilateral
- Other anomalies may be associated
-
Developmental Disorder
- Radial head dislocates posterolaterally
- Result of Cerebral Palsy or neurologic injury
IV. Differential Diagnosis
V. Imaging: Elbow XRay
- Draw line through long axis of radius
- Line should always pass through capitellum in any view
VI. Management
-
Traumatic dislocation
- Early reduction to prevent stiffness and pain
- Surgery for old neglected dislocations
- Congenital or Developmental Dislocations
- Management not needed if:
- No pain
- Little or no functional Impairment
- Management not needed if:
