  • 4G: Impaired Joint Mobility, Muscle Performance, and Range of Motion Associated With Fracture

++

Description

++

  • Fracture
  • Any defect in continuity of the radial head or neck
  • Displaced (radial head/neck is moved on either side of the fracture) or nondisplaced (radial head/neck has not moved)
  • Closed (skin is intact) or open (skin is breached)

++

Essentials

++

  • Diagnosis is usually made by clinical examination
  • May not be a fracture but a proximal radioulnar subluxation/dislocation, humeroradial subluxation/dislocation, radial collateral ligament sprain

++

General Considerations

++

  • Radius is the most commonly broken bone in the arm.
  • Occurs in about 20% of all acute elbow injuries

++

Demographics

++

  • More frequent in women than in men
  • Occurs most often between 30 and 40 years of age

++

Signs and Symptoms

++

  • Pain on the outside of the elbow
  • Point tenderness
  • Edema
  • Ecchymosis
  • Loss of general function
  • Loss of active elbow movement
  • Loss of active forearm movement (supination/pronation)
  • Muscle guarding with passive movement
  • Crepitus

++

Functional Implications

++

  • Pain with weight-bearing activities on involved upper extremity (UE)
  • Pain with vertical positioning of arm at side
  • Pain with all elbow and forearm movements (passive or active)

++

Possible Contributing Causes

++

  • Mechanism of injury
    • Fall on outstretched hand
    • Blunt or penetrating trauma is a rare cause

++

Differential Diagnosis

++

  • Proximal radioulnar subluxation/dislocation
  • Humeroradial subluxation/dislocation
  • Radial collateral ligament sprain

++
