Glutaraldehyde treated bovine fibrocartilage arthroplasty for the scaphoid: a case history and discussion.

Avascular necrosis of the proximal pole of the carpal scaphoid following fracture often leads to degeneration and carpal collapse. Replacement arthroplasty as a treatment for this condition using a variety of materials has not been universally successful. A case is described in which a new arthroplasty material-glutaraldehyde treated bovine fibrocartilage-was used as a spacer to restore carpal height.
