Related to ulnar deviation: subluxation, carpal tunnel syndrome, ulnar drift


1. a turning away from the regular standard or course.
2. in ophthalmology, strabismus.
3. in statistics, the difference between a sample value and the mean.
axis deviation an axis shift in the frontal plane, as seen on an electrocardiogram. There are three types: Left, from −30° to −90°; Right, from +90° to +180°; and Undetermined, which may be either extreme left or extreme right, from −90° to +180°.
conjugate deviation dysfunction of the ocular muscles causing the two eyes to diverge to the same side when at rest.
sexual deviation sexual behavior or fantasy outside that which is morally, biologically, or legally sanctioned, often specifically one of the paraphilias.
standard deviation (SD) the dispersion of a random variable; a measure of the amount by which each value deviates from the mean. It is equal to the square root of the variance. For data that have a normal distribution, about 68 per cent of the data points fall within (plus or minus) one standard deviation from the mean and about 95 per cent fall within (plus or minus) two standard deviations. Symbol σ.
ulnar deviation a hand deformity, seen in chronic rheumatoid arthritis and lupus erythematosus, in which swelling of the metacarpophalangeal joints causes the fingers to become displaced to the ulnar side. Called also ulnar drift. See illustration.

observed wrist orientations at two different speeds (1.3 and 2.2 m/s) and observed that mean maximum flexion, extension, and ulnar deviation angles did not change with speed [10].

The study variables were measured and documented at the baseline including, age, gender, dominant hand, hand involved, prior level of activity, pain intensity score, Thumb function score, and PROM of wrist flexion, extension, radial and ulnar deviation (Table-I).
The exposure is made with the wrist in ulnar deviation and the resultant radiograph demonstrates the magnified scaphoid.
Some research evidence indicates reduced discomfort with this kind of design because of reduced ulnar deviation. These designs do not usually address wrist extension issues.
Mean flexion/extension of the wrist and radial/ ulnar deviation postural data were determined for the third cycle of task completion for all conditions.
Avoid activities requiring excessive up-and-down (flexion and extension) and side-to-side (radial and ulnar deviation) movements of the wrist as much as possible.
(12) described perilunate injuries as the result of sequential intercarpal wrist instability that occurs following a reproducible injury pattern: wrist hyperextension, ulnar deviation, and intercarpal supination with an axial load.
The exact mechanism of the injury is unknown; however, previous reports have suggested that high-energy motor vehicle accidents with forced wrist dorsiflexion of the hand in ulnar deviation may result in the scaphoid leaving its fossa [3].
Reduction was done with wrist in palmar flexion and ulnar deviation. The adequacy of the reduction was checked under C-arm and then below elbow POP slab was given.
(16) Riding in the tops hand position produce the greatest ulnar deviation. (16) In these cycling postures, sustained compression of the ulnar nerve ensues.
A major change in gen 3 was the compound wrist, which combined movements of ulnar radial deviation with wrist flexion and movements of ulnar deviation with wrist extension.
