This study examined the anatomy of approximately 100 normal wrist MRIs and XRays and approximately 100 wrists with ulnar sided wrist pathology. We examined the impact of cartilage (which can only be viewed on MRI) on the height or “variance” of the ulna. A normative study design was used to describe the normal standard values for the anatomy of the ulnar in normal wrists which will later be compared to the values of wrists with ulnar sided pathology.
