| Minimum distance watershed line—PQ | 3.5 | 1.2–7.2 |
| Maximum distance watershed line—PQ | 7.6 | 3.6–10.6 |
| Ulnar prominence—PQ | 7.2 | 2.3–10.0 |
| Radial prominence—PQ | 2.8 | –1.3–0.5 b |
| Interfossa sulcus—PQ | 4.8 | 1.7–7.4 |
Abbreviation: PQ, pronator quadratus.
a
Measurement performed in eight specimens, as in two specimens the radial prominence was located more radially than the radial border of the joint line.
b
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).
