Ulnar variance varies amongst the population [7].
Ulnar variance was measured on all x-ray films.
The ulnar variance at the wrist is measured by fluoroscopy.
Some patients in this group need treatment for their positive ulnar variance, usually by ulnar shortening osteotomy. .
Sanderson et al. [7] evaluated ulnar variance in over 1,000 cohorts and found that ulnar variance decreases with age.
+ Positive ulnar variance.
The regression analysis showed an association between temperature variation and nerve conduction velocity values for the median and ulnar nerve at T2 as compared to T1.
The specificity of this effect is further demonstrated by the non-significant variation of motor evoked potentials in the abductor digiti minimi muscle, innervated by a different nerve (ulnar) respect to that one for the conditioning stimulation (median).
The rest of upper limb arterial flows did not show significant variations when compared with FlowSRC or FlowNOCATH; however, they showed a tendency to increase in the ulnar and brachial arteries and decrease in the subclavian arteries.
