Elbow arthroplasty: replacement of distal humerus and proximal ulna portions of elbow joint
Hinged implant
Implant is stable
Semiconstrained/linked implant
Uses pin, which allows small amount of rotation and varus-valgus angulation (7-10°)
Most commonly used total elbow prosthesis
Convertible implant
Allows surgeon to choose between semiconstrained and unconstrained mechanism
Unlinked or uncoupled implant
Inherently less stable than hinged implant
Requires normal underlying bone stock
Stabilizing soft tissues must be intact (muscles, tendons, and collateral ligaments)
Increased rate of dislocation (13%) but decreased rate of loosening
Hemiarthroplasty: replacement of only 1 portion of joint
Humeral and ulnar hemi-implants not used secondary to high failure rate
Radial head implant used but has high rate of failure
Unipolar or bipolar (allows rotation of head up to 15°)
Capitellum resurfacing
Often used with radial head implant for lateral elbow resurfacing
Arthroplasty is procedure; device = prosthesis, implant, replacement
