Arthritis of the STT or scaphoid-trapezium-trapezoid joint is a condition that usually occurs along with arthritis of the CM or carpometacarpal joint of the thumb [14]. Since that area is above the curve, but inside the trapezoid, it’ll get included in the trapezoidal rule estimate, even though it shouldn’t be because it’s not part of the area under the curve. Routine anteroposterior, lateral, and oblique radiographs of the hand cannot be depended upon to provide adequate visualization of all … In Euclidean geometry, a convex quadrilateral with at least one pair of parallel sides is referred to as a trapezoid () in American and Canadian English but as a trapezium () in English outside North America.
