radiocarpal arthrodesis
Surgical fusion of the radius and carpal bones to eliminate painful wrist motion.
Full Definition
Radiocarpal arthrodesis is a salvage procedure that fuses the distal radius to the proximal carpal row, typically including the scaphoid, lunate, and sometimes the triquetrum. This procedure eliminates motion at the radiocarpal joint while preserving some wrist movement through the midcarpal joint. It is indicated for severe post-traumatic arthritis, failed wrist arthroplasty, or irreparable ligamentous injuries. The procedure provides pain relief and functional grip strength but results in approximately 50% loss of wrist motion compared to total wrist arthrodesis.
Usage
Usage note: Distinguish from total wrist arthrodesis which includes midcarpal joints.
