Muscle hypoxia in rheumatoid hands: does it play a role in ulnar drift?
The intrinsic muscle weakness, intrinsic tightness, and muscle wasting observed in RA may not be due to disuse atrophy resulting from joint disease. From our data, we speculate that these changes may be the result of direct muscular involvement in RA leading to muscle hypoxia.
After adjusting for confounders, MOI was found to independently predict mortality and functional impairment at hospital discharge. Current injury assessment models could be greatly enhanced by including MOI, and we propose routine adjustment for injury mechanism in trauma outcomes research.
