Cubital

   1. Pertaining to the elbow. 2. Pertaining to the forearm and hand. 3. Pertaining to the ulna.

RELATED TERMS
--------------------------------------

Elbow
The juncture of the long bones in the middle portion of the arm. The bone of the upper arm (humerus) meets both the ulna (the inner bone of the forearm) and radius (the outer bone of the forearm) to form a hinge joint at the elbow. The radius and ulna also meet one another in the elbow to permit a small amount of rotation of the forearm. The elbow therefore functions to move the arm like a hinge (forward and backward) and in rotation (outward and inward). The biceps muscle is the major muscle that flexes the elbow hinge, and the triceps muscle is the major muscle that extends it. The primary stability of the elbow is provided by the ulnar collateral ligament, located on the medial (inner) side of the elbow. The outer bony prominence of the elbow is the lateral epicondyle, a part of the humerus bone. Tendons attached to this area can be injured, causing inflammation or tendonitis (lateral epicondylitis, or tennis elbow). The inner portion of the elbow is a bony prominence called the medial epicondyle of the humerus. Additional tendons from muscles attach here and can be injured, likewise causing inflammation or tendonitis (medial epicondylitis, or golfer's elbow).

Forearm
The portion of the upper limb from the elbow to the wrist. In popular usage, the arm extends from the shoulder to the hand. However, in medical terminology, the arm refers to the upper extremity extending from the shoulder only to the elbow. The arm is thus distinguished in medical usage from the forearm, which extends from the elbow to the wrist.The forearm has 2 bones: the radius and ulna.

Ulna
Forearm bone on the side of the little finger.

Cubicin
Cubicin is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): daptomycin.

Cubital tunnel
The opening between the two heads of a muscle through which the ulnar nerve passes at the elbow and enters the forearm. (The muscle is called the flexor carpi ulnaris.) Compression of the ulnar nerve in this passageway results in the cubital tunnel syndrome.

Cubital tunnel syndrome
A form of mononeuropathy due to compression or other injury of the ulnar nerve at the elbow. Symptoms of the cubital tunnel syndrome may include pain and numbness along the ulnar aspect (the little finger side) of the hand and forearm, and weakness of the hand.

Cubital Tunnel Syndrome
Compression of the ULNAR NERVE in the cubital tunnel, which is formed by the two heads of the flexor carpi ulnaris muscle, humeral-ulnar aponeurosis, and medial ligaments of the elbow. This condition may follow trauma or occur in association with processes which produce nerve enlargement or narrowing of the canal. Manifestations include elbow pain and PARESTHESIA radiating distally, weakness of ulnar innervated intrinsic hand muscles, and loss of sensation over the hypothenar region, fifth finger, and ulnar aspect of the ring finger. (Joynt, Clinical Neurology, 1995, Ch51, p43)

Cubitus
1. The elbow. 2. The forearm and hand. 3. The ulna.

Cubitus valgus
A deformity of the elbow resulting in an increased carrying angle (so that, with the arm extended at the side and the palm facing forward, the forearm and hand are held at greater than 15 degrees). Cubitus valgus can be due to a congenital malformation, as in Turner syndrome and Noonan syndrome, or be due to a fracture.

Cubitus varus
A deformity of the elbow resulting in a decreased carrying angle (so that, with the arm extended at the side and the palm facing forward, the forearm and hand are held at less than 5 degrees). There is deviation of the forearm toward the midline of the body. Cubitus varus is also called the gun stock deformity.

Computerized tomography scan. Pictures of structures within the body created by a computer that takes the data from multiple X-ray images and turns them into pictures on a screen. CT stands for computerized tomography.

CT, electron beam
Also known as Ultrafast CT (computerized tomography), this is a new (and controversial) noninvasive test for the detection of coronary artery disease (CAD). It is designed to measure calcium deposits in the coronary arteries.
