A TFCC tear is an injury to the triangular fibrocartilage complex, found in the wrist, between the end of the ulna bone and the carpals. Its function is to stabilize the radioulnar joint.
As in simpler alkanes, carbon in the CFCs and the HCFCs is tetrahedral. Because the fluorine and chlorine atoms differ greatly in size and effective charge from hydrogen and from each other, the methane-derived CFCs deviate from perfect tetrahedral symmetry.nce the partial pressure of the CFC (or SF 6) is derived, it is then compared to the atmospheric time histories for CFC-11, CFC-12, or SF 6 in which the pCFC directly corresponds to the year with the same measurement.
