Abbreviation: PQ, pronator quadratus.
Measurement performed in eight specimens, as in two specimens the radial prominence was located more radially than the radial border of the joint line.
Including two specimens in which the radial prominence was situated respectively 0.2 and 1.3 mm more proximal than the most radial point of the PQ (expressed in a negative value).
