arthroplasty
Pronunciation: ar-THROP-las-tee
Surgical reconstruction or replacement of a joint, often performed as salvage treatment for severe trauma.
Full Definition
Arthroplasty is a surgical procedure involving reconstruction or replacement of a joint using artificial components (prostheses) or biological tissue. In orthopedic trauma, arthroplasty may be indicated as primary treatment for complex periarticular fractures in elderly patients or as salvage therapy for post-traumatic arthritis, osteonecrosis, or failed internal fixation. Common procedures include total hip arthroplasty for femoral neck fractures and shoulder arthroplasty for proximal humerus fractures.
Usage
Usage note: Specify type (total, partial, reverse, etc.) when documenting; not synonymous with arthroscopy.
