What is ulnar head replacement?
What does this involve? This involves removing the arthritic end of your ulna bone replacing it with an artificial joint. The end of the ulna bone is called the ulnar head and the joint it makes with the end of the radius is called the distal radioulnar joint (DRUJ). Various types of replacement are available.
What is the ulna head?
The lateral, distal end of the ulna is the head of the ulna. It articulates with the ulnar notch on the radius and with the triangular articular disc in the Wrist Joint.
Is there an ulnar head?
The ulnar head is a thin fasciculus, which arises from the medial side of the coronoid process of the ulna, and joins the preceding at an acute angle.
How is ulnar subluxation treated?
Treatment of simple subluxation in the acute setting consists of immobilization in a reduced position: the position of the forearm should be neutral for bidirectional instability, supination for ulna dorsal dislocations, and pronation for ulna volar dislocations, for six weeks in an above-elbow cast. .
Where is the ulnar tuberosity?
The ulnar (or brachial) tuberosity is a roughened depression immediately inferior to the coronoid process. It marks the insertion of the brachialis muscle, a flexor of the elbow that originates from the anterior surface of the humerus.
What is the purpose of ulna?
The ulna is a long bone in the forearm. It lies medially and parallel to the radius, the second of the forearm bones. The ulna acts as the stabilising bone, with the radius pivoting to produce movement. Proximally, the ulna articulates with the humerus at the elbow joint.
Is the ulna on the pinky side?
What is ulnar wrist pain? Ulnar wrist pain occurs on the outside (pinkie-finger side) of your wrist. The ulna is the arm bone that ends at the wrist on this side.
Can you damage your ulnar nerve?
Ulnar neuropathy occurs when there is damage to the ulnar nerve. This nerve travels down the arm to the wrist, hand, and ring and little fingers. It passes near the surface of the elbow. So, bumping the nerve there causes the pain and tingling of “hitting the funny bone.”
What causes ulnar subluxation?
Ulnar nerve, being in close proximity to the elbow joint is predisposed to trauma and entrapment neuropathy where it courses through the cubital tunnel. Subluxation or dislocation of the nerve at this site could occur as a result of trauma or variations in the anatomical structures posterior to elbow joint.
