This permits “bone-on-bone” apposition which is the unique feature which facilitates the unique short-segment correction of the flexible curves which are ideal for this approach. Median and range were calculated for descriptive numbers. The reverse is also true — an x-ray may show changes that point to advanced osteoarthritis while you may be experiencing few if any, symptoms. Bone apposition,interleukin-6,Oncostatin M,RANK,RANKL Context Oncostatin M (OSM) is a member of the interleukin (IL)-6 family and induces the expression of IL-6.
