What is the radial tuberosity of the radius?
Anatomical terms of bone 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. an anterior, smooth portion, on which a bursa is interposed between the tendon and the bone.
What is the significance of the radial tuberosity?
Background: The radial tuberosity contributes to the biceps supination moment arm and the elbow flexion moment. The purpose of our study was to compare the impact of a cortical bone trough versus an anatomic repair on measurements of the forearm supination moment arm and elbow flexion force efficiency.
Which muscle inserts onto the radial tuberosity?
Biceps brachii muscle
| Origin | Short head – Apex of the Coracoid process of the scapula Long head – Supraglenoid tubercle of the scapula Mnemonic: ‘You walk Shorter to a street Corner. You ride Longer on a Superhighway’ |

| Insertion | Radial tuberosity of the radius Deep fascia of forearm (insertion of the bicipital aponeurosis) |
Where is Bicipital tuberosity located?
an oval projection from the medial surface of the radius just distal to the neck, giving attachment (insertion) on its posterior half to the tendon of the biceps.
Where is the radial tuberosity located quizlet?
Where is the radial tuberosity located? The radial tuberosity is distal to the medial part of the neck, and demarcates the promixal end (head and neck) of the radius from the shaft.
What is the function of the styloid process of the radius?
The radial styloid process projects obliquely downward from the distal end of the radius. It serves as the point of attachment for the brachioradialis muscle and the radial collateral ligament. Laterally, the tendons of extensor pollicis brevis and abductor pollicis longus run in a flat groove.
What muscles attach to the radius?
Muscle attachments[edit | edit source] Biceps brachii attaches to the radial tuberosity. Supinator, flexor pollicis longus and the flexor digitorum superficialis attach to the upper third part of the shaft of the radius.
Is Bicipital tuberosity same as radial tuberosity?
The radial tuberosity (bicipital tuberosity) is a blunt, rugose, variably shaped structure on the anteromedial side of the proximal radius.
What does the radial tuberosity articulate with?
The head of the radius is disk-shaped; its upper concave surface articulates with the humerus (upper arm bone) above, and the side surface articulates with the ulna. On the upper part of the shaft is a rough projection, the radial tuberosity, which receives the biceps tendon.
What landmark on the humerus articulates with the radius?
capitulum
Immediately lateral to the trochlea is the capitulum (“small head”), a knob-like structure located on the anterior surface of the distal humerus. The capitulum articulates with the radius bone of the forearm.
What is radial tuberosity?
Radial tuberosity – WikiMili, The Best Wikipedia Reader Beneath the neck of the radius, on the medial side, is an eminence, the radial tuberosity; its surface is divided into: Beneath the neck of the radius, on the medial side, is an eminence, the radial tuberosity; its surface is divided into:
What is bicipital tuberosity and why is it important?
The anatomy of the distal biceps tendon and bicipital tuberosity (BT) is important in the pathophysiology of tendon rupture, as well as surgical repair. Understanding the dimensions of the BT and its angular relationship to the radial head and radial styloid will facilitate surgical procedures such …
What is the proximodistal dimension of ulnar tuberosity?
For an isolated proximal end, the tuberosity faces anteromedially. The medial portion of the proximal ulnar articular surface has the greatest proximodistal dimension. There is a small ridge on the posteromedial aspect of the neck, congruent with the superior aspect of the medial edge of the radial tuberosity.
What is pseudocyst in radial tuberosity?
The radial tuberosity on lateral projections can create an ovoid radiolucent lesion like appearance (“pseudocyst”), which is proven to be artefactual on the AP view. 1. Mhuircheartaigh JN, Lin YC, Wu JS. Bone tumor mimickers: A pictorial essay.
