Radius fracture after total wrist arthroplasty.

Four cases of radius fracture are presented; each was caused by a fall and happened at least 18 months after total wrist arthroplasty. One patient had bilateral fractures occurring 12 months apart. All injuries were initially treated nonoperatively. Nonunion or healing with deformity occurred in three fractures. Revision arthroplasty was done in two cases with satisfactory results, and is being considered for a third.
