Presentation Transcript


Elbow Dislocation


  • 3-6% of all elbow injuries

  • Peak: 13-14 yrs after closure of physes

  • High association with the following fractures

    • Medial epicondyle

    • Coronoid

    • Radial head and neck


  • Modified hinge joint

  • Very stable

    • Joint congruity

    • Opposing tension of triceps and flexors

    • Ligaments

      • Most important: Medial Collateral Ligament


Mechanism of Injury

  • Fall on an outstretched hand o elbow

    • Causes unlocking of the olceranon from the trochlea + translation of the articular surfaces

  • 2 types of dislocation

    • Posterior

    • Anterior


Malunion Discussion


Malunion

  • Described to be a fractured bone that did not heal in an anatomic position

  • Bone may have:

    • Angulated

    • Rotated out of position

    • Overlapped with another bone


  • Caused by:

    • Inadequate immobilization

    • Misalignment

    • Premature removal of an immobilizer


Non-union

  • A fracture that did not heal after a span of several months

  • Caused by:

    • Overdistraction

    • Excessive motion

    • Inadequate immobilization


Risk factors for poor fracture healing

  • Smoking

  • Excessive alcohol intake

  • Malnutrion

  • Diabetes

  • NSAID, corticosteroids

  • Anticonvulsants and Thyroid Hormone Replacement


Presentation

  • History

    • A fracture that was not brought to a physician

    • Deformity

    • Pain, edema

    • Instability

  • PE

    • Deformity and tenderness
