When Simi begins to palpate Mary's joints, she finds her stride, spilling out technical terms as she goes: symmetrical deformity; ulnar deviation at the MCP joint; rheumatoid nodules, widespread over all joints; Z-thumb deformity; fixed flexion deformity on all fingers; swan neck deformity… The list seems endless, and Karan is impressed, needing to prompt Simi only once or twice.
No flexion is involved, so using rigid ceramics is not a problem.
The last of these is often recommended by family doctors as the safest for sore backs.In this section Fast-tracking treatments Caging the Li-ion Assume the position ReprintsMost back problems in younger folk are triggered by bending forward, a movement called flexion.
To facilitate cursorial, or running, habits, flexion is limited to one plane.
Success has been achieved with a surgical procedure in which a triangular piece of the ITB is resected from the area overlying the lateral femoral epicondyle when the knee is in the critical position of 30° flexion.
Their primary action is adduction of the thigh, as in squeezing the thighs together; they also aid in rotation and flexion of the thigh.
Because of the attachment of the spine to the base of the skull, the back of the head advances more rapidly than the brow with the result that the head becomes flexed (i.e., the neck is bent) until the chin comes to lie against the breastbone (see flexion in the figure).
As a consequence of this flexion mechanism, the top of the head becomes the leading pole and the ovoid head circumference that entered the birth canal is succeeded by a smaller, almost circular circumference, the long diameter of which is about 2 centimetres (0.75 inch) shorter than that of the earlier circumference.
Thus, as extension (bending of the head backward) takes the place of flexion, the occiput, brow, eye sockets, nose, mouth, and chin pass successively through the external opening of the lower birth canal and are born (see extension in the figure).
Similar to living pinnipeds, Enaliarctos had hind limbs that were specialized as flippers, and the vertebral column was specialized for strong flexion and extension.
Typically, iliotibial band syndrome (ITBS) results from overuse injury, seen most commonly in distance runners and other athletes whose sports require a great degree of knee flexion.
