Glossary

Treatment depends on 1) Associated injuries that may create elbow or forearm instability, and 2) Restriction of forearm rotation.

Nonoperative
Indication summary Skill Equipment
Non- or minimally displaced fractures with no restriction of forearm rotation Basic surgical experience, no specialized skills Basic equipment only

Note: Nonoperative treatment is generally only indicated if functional forearm rotation can be demonstrated with or without anesthetic injection.

Contraindications

  • Presence of elbow or forearm subluxation
  • Infirm or dependent person
  • Polytrauma

Advantages

  • Allows immediate motion and stretching exercises to avoid elbow stiffness

Disadvantages

  • Malunion of the radial head restricting forearm rotation and elbow subluxation can be difficult to salvage later.
Lag screw
Indication summary Skill Equipment
Simple displaced fractures Highly experienced and skilled surgeon Simple surgical and imaging resources

Contraindications

  • Multifragmentary fracture

Advantages

  • Anatomical reduction
  • Good interfragmentary compression

Disadvantages

  • Risk of joint penetration
  • Risk of additional fracture
Radial head excision
Indication summary Skill Equipment
Isolated unreconstructable radial head fracture with stable elbow but limited forearm rotation. Intact interosseous membrane and distal radioulnar joint (DRUJ). Some specialized surgical experience Basic equipment only

Contraindications

  • Simple fracture
  • Associated coronoid fracture (>50%)
  • DRUJ injury

Advantages

  • Fast procedure
  • Good functional recovery
  • Inexpensive and easy technique

Disadvantages

  • Risk of missed Essex-Lopresti injury
  • Risk of unstable elbow after wrong diagnosis
  • Risk of late proximal migration of the radius
Radial head arthroplasty
Indication summary Skill Equipment
Inability to reconstruct radial head fracture so that it provides sufficient stability for elbow joint. Interosseous membrane injury (Essex-Lopresti injury). Highly experienced and skilled surgeon Full specialized surgical and imaging resources

Further indications

  • Unreconstructable radial head fracture associated with an unstable fracture of the coronoid process
  • After radial head excision with evidence of medial collateral ligament insufficiency or ulnohumeral instability
  • Unreconstructable radial head fracture with acute distal radioulnar joint injury (Essex-Lopresti injury)

Contraindications

  • Simple fracture
  • Reconstructable multifragmentary fracture
  • Stable elbow

Advantages

  • Fast procedure
  • Good functional recovery
  • Stable elbow

Disadvantages

  • Early loosening of the prosthesis
  • Risk of elbow stiffness (prosthesis too large)
  • Risk of unstable elbow (prosthesis too small)
