Definitions for "Hemiarthroplasty"
Surgical repair of a joint, in which one joint surface is replaced with artificial material, usually made of metal. In the case of the TMJ, when only the fossa-eminence is reconstructed with a metal implant (partial joint reconstruction). See also, fossa-eminence prosthesis.
a quicker operation than a total hip replacement and therefore theoretically safer (less anesthesia time, less bleeding, less exposure to the air)
arthroplasty in which one joint surface is replaced with artificial material, usually metal. In shoulder hemiarthroplasty, the proximal humerus is usually replaced, rather than the glenoid.
