Assessing periprosthetic bone in total wrist arthroplasty: The validity of DXA
Journal of clinical densitometry
Dual-energy X-ray absorptiometry (DXA) can measure bone mineral density (BMD) around joint arthroplasties. DXA has never been used in total wrist arthroplasties (TWA). We investigated (1) whether BMD differs between 2 TWAs implanted in the same cadaver forearm, (2) the effect of forearm rotation and wrist extension on measured BMD around TWA in a cadaver, and (3) the precision of DXA in a cadaver and patients. One ROI around the distal and 1 and 3 ROIs (ROI1-3) around the proximal componentdoi:10.1016/j.jocd.2020.10.006 pmid:33172804 fatcat:abaqej2y6fdo5m4ruskg5gez5m
