Lister's tubercle is found on the dorsal distal radius. [1] It varies in size and shape significantly. [2] [3] It can range from around 2 to 6 mm in height (averaging 3 mm), and around 6 to 26 mm in length (averaging 13 mm). [2] [3] Lister's tubercle consists of two peaks including radial peak and ulnar peak. [4]
Anatomical snuff box. People with scaphoid fractures generally have snuffbox tenderness.. Focal tenderness is usually present in one of three places: 1) volar prominence at the distal wrist for distal pole fractures; 2) anatomic snuff box for waist or midbody fractures; 3) distal to Lister's tubercle for proximal pole fractures.
The most prominent tubercle of the tibia, a leg bone which is more commonly known as the shinbone or shankbone, is the tibial tuberosity. The tibial tuberosity is located on the tibia's anterior surface, distal to the medial condyle. It creates a bony prominence just below the patella, and can be easily located with the fingers.
Beneath the neck of the radius, on the medial side, is an eminence, the radial tuberosity; its surface is divided into: a posterior, rough portion , for the insertion of the tendon of the biceps brachii .
The distal end of the radius forms two palpable points, radially the styloid process and Lister's tubercle on the ulnar side. Along with the proximal and distal radioulnar articulations , an interosseous membrane originates medially along the length of the body of the radius to attach the radius to the ulna.
De Quervain syndrome causes pain over the styloid process of the radius. [3] [4] This is due to the passage of the inflamed extensor pollicis brevis tendon and abductor pollicis longus tendon around it. [4] [5] The styloid process of the radius is a useful landmark during arthroscopic resection of the scaphoid bone. [6]
The carpal bones function as a unit to provide a bony superstructure for the hand. [5]: 708 The scaphoid is also involved in movement of the wrist. [1]: 6 It, along with the lunate bone, articulates with the radius and ulna to form the major bones involved in movement of the wrist. [5]
English: Computer Generated 3d Model showing: Posterior View of Right Distal Radius. you can see the interosseous border, posterior border, posterior and lateral surfaces, dorsal tubercle, groove for extensor carpi radialis, radial styloid process, ulnar notch, groove for the extensor muscle tendons and groove for extensor pollicis longus.
