The radial notch of the ulna (lesser sigmoid cavity) is a narrow, oblong, articular depression on the lateral side of the coronoid process; it receives the circumferential articular surface of the head of the radius. It is concave from before backward, and its prominent extremities serve for the attachment of the annular ligament.
The radial notch is the smooth, oval, articular indentation found along the lateral aspect of the coronoid process of ulna. Its anterior and posterior margins provide attachment sites for the annular ligament of the radius. The radial notch of ulna articulates with the medial portion of the articular circumference of the head of the radius ...

31 Ιουλ 2024 · radial head: radial notch of the proximal ulna (site of supination and pronation) distal. distal radius facet: scaphoid and lunate fossae separated by a small ridge. volar tilt: approximately 11 o of tilt on the lateral view. radial inclination: approximately 22 o of inclination on the frontal view. ulnar notch: ulna head (site of supination ...
Radial notch: This is the indentation just lateral to the coronoid process on the proximal portion of the bone. Similar to the ulnar notch of the radius, the radial notch of the ulna is named for the bone/feature that articulates with it.
coronoid fractures and radial head injuries often exhibited involvement of the coronoid anterolateral facet. This type of anterolateral or oblique lateral fractures can include the radial notch (RN), which forms the ulnar articular surface of the proximal radioulnar joint (Fig. 1 a, b). So far, the extent * Krishnan Sircar
22 Μαρ 2019 · The most distal aspect of the greater SN where the notch intersects with the most ulnar aspect of the lunate facet was chosen as the joint line (0 mm). The red line represents the distal radius central axis (DRCA), a line joining the radial styloid point and the center of the SN.
