It is an area cubitla transition between the anatomical arm and forearm which several important structures traverse through.

This article focuses on the anatomy and clinical relevance of the cubital fossa. The cubital fossa is a three-dimensional space which has a superior, lateral and medial border, as well as a roof and floor.

It is bordered by two forearm muscles Ч brachioradialis laterally and pronator teres medially. The medial border of the cubital fossa is formed by the pronator teres muscle which originates from the medial epicondyle. This muscle is innervated by the median nerve and is located in the anterior compartment of the forearm. The lateral border of the cubital fossa is formed by the brachioradialis which originates from the lateral supra-epicondylar ridge of the humerus.

This muscle is innervated by the radial nerve, as it is located in the posterior compartment of the forearm. The superior border of the cubital fossa which forms the base of the triangle is marked by an imaginary transverse line what is the cubital fossa between the fkssa and lateral epicondyles of the humerus a. The floor of the cubital fossx is formed mainly by the brachialis muscle proximally and the supinator muscle distally.

The roof of the cubital fossa is formed by fascia and skin. The roof of the fossa is covered by the bicipital aponeurosiswhich confers some protection to the median nerve and brachial artery. The contents of the cubital fossa fosda the median nerveradial nervebrachial artery and biceps tendon Ч these will be discussed in greater detail below. The radial nerve is located adjacent to the cubital fossa, anterior to the elbow and deep to the brachioradialis muscle.

Strictly speaking, it is not considered to be contained how to remove dui from record the cubital fossa but it does pass closely through the area under brachialis. The radial nerve typically bifurcates close to the cubital fossa into a superficial and deep branch.

The deep branch is solely responsible for motor function and supplies the muscles of the posterior compartment of the forearm. It passes between the supinator muscle heads and fosa name changes to become the posterior interosseous nerve which passes close to the radial neck and is responsible for motor function only. The biceps tendon passes centrally through the cubital fossa and attaches to the radial tuberosity of the radius.

The biceps tendon is relatively easy to identify by palpation and can be used as a useful landmark for the other contents of the cubital fossa. Medial to the biceps tendon is the brachial artery and median nerve. The brachial pulse is key to measuring blood pressure manually with whqt sphygmomanometer.

The brachial artery is first palpated and then auscultated to listen for Korotkoff sounds which appear and disappear during inflation and deflation of the sphygmomanometer allowing systolic and diastolic blood pressure to what is the cubital fossa measured. The brachial artery is a continuation of the axillary artery and sits just medial to the biceps tendon within the cubital fossa.

The median nerve lies most medially what is the cubital fossa the cubital fossa, immediately medial to the brachial artery. The median nerve exits the cubital fossa between the two heads of the ulnar and humeral heads of pronator teres.

The median nerve has an important what does a recreation therapist do in wrist flexion, forearm pronation and movements of the digits by innervating most of the muscles of the anterior compartment of the forearm.

As a side note; the ulnar nerve does not pass through the cubital fossa. The ulnar nerve passes down what is a baby spider called medial side of the forearm through the cubital tunnel and passes what is the cubital fossa to the medial epicondyle to enter the anterior forearm. The superficial veins of the cubital fossa lie superior to the roof of the fossa and are separated from the brachial artery and median nerve by the bicipital aponeurosis.

The superficial veins what is the cubital fossa the cubital fossa include the basilic vein located medially, the cephalic vein located laterally and the median cubital vein which connects these two veins together. The superficial veins located superior to the cubital fossa are often used in procedures such as venepuncture and intravenous cannulation. The aponeurosis confers an element of protection to the brachial artery and median nerve in this instance. A supracondylar fracture of the humerus is a relatively common fracture in children.

As the elbow is hyper-extended in this instance, a fracture can occur between the medial and lateral epicondyles. Anatomical knowledge is essential for preventing iatrogenic injury during surgery. Patients in renal failure requiring dialysis undergo a procedure to create an arteriovenous fistula which is a connection between how to put dell computer back to factory settings artery and a vein.

The brachial artery and cephalic vein wgat commonly used to create an arteriovenous fistula. This vein must be large enough to withstand the higher pressures associated with the arterial circulation. Clinical Examination. Cbital Murmurs. Eye Drops Overview.

Clinical Relevance: Supracondylar Fracture

Nov 06, †Ј The cubital fossa (a.k.a. antecubital fossa) is a triangular space located anterior to the elbow joint. The Cubital Fossa is a triangular-shaped depression, located between the forearm and the arm on the anterior surface of the elbow, with the apex of the triangle pointing distally. It is also known as the УantecubitalФ because it lies anteriorly to the elbow. It is a space filled with different structures that makes up its content.

The cubital anticubital fossa is a triangular-shaped depression over the anterior aspect of the elbow joint. It represents an area of transition between the anatomical arm and the forearm , and conveys several important structures between these two areas. In this article, we shall look at the anatomy of the cubital fossa Ч its borders, contents and clinical relevance. Fig 1 Ч The cubital fossa is a triangular-shaped depression over the anterior aspect of the elbow.

The cubital fossa is triangular in shape and consists of three borders, a roof, and a floor:. Fig 2 Ч The medial and lateral borders of the cubital fossa are formed by the muscles of the anterior forearm. The cubital fossa is a passageway for structures to pass between the upper arm and forearm. The roof of the cubital fossa also contains several superficial veins. Notably, the median cubital vein , which connects the basilic and cephalic veins and can be accessed easily Ч a common site for venepuncture.

A supracondylar fracture is a fracture of the distal humerus. The fracture is typically transverse or oblique, and the most common mechanism of injury is falling on an outstretched hand. It is more common in children than adults. In this type of injury, the contents of the cubital fossa can be damaged Ч either directly, or by soft tissue swelling following the trauma.

There also can be damage to the anterior interosseous nerve branch of the median nerve , ulnar nerve or radial nerve. Type 1 can usually be managed conservatively with an above elbow cast whereas types 2 and 3 typically require surgical fixation with crossed, bi-cortical k-wires.

In this article, we shall look at the anatomy of the cubital fossa - its borders, contents and clinical relevance. In this type of injury, the contents of the cubital fossa can be damaged - either directly, or by soft tissue swelling following the trauma.

By TeachMeSeries Ltd Borders The cubital fossa is triangular in shape and consists of three borders, a roof, and a floor: Lateral border Ч medial border of the brachioradialis muscle.

Medial border Ч lateral border of the pronator teres muscle. Superior border Ч horizontal line drawn between the epicondyles of the humerus. Roof Ч bicipital aponeurosis, fascia, subcutaneous fat and skin. Floor Ч brachialis proximally and supinator distally.

Contents The cubital fossa is a passageway for structures to pass between the upper arm and forearm. Its contents are lateral to medial : Radial nerve Ч travels along the lateral border of the cubital fossa and divides into superficial and deep branches.

It has a motor and sensory function in the posterior forearm and hand. Biceps tendon Ч passes centrally through the cubital fossa and attaches the radial tuberosity immediately distal to the radial neck.

It gives rise to the bicipital aponeurosis which contributes to the roof of the cubital fossa. Brachial artery Ч bifurcates into the radial and ulnar arteries at the apex of the cubital fossa. The brachial pulse can be felt in the cubital fossa by palpating medial to the biceps tendon Median nerve Ч travels medially through the cubital fossa, exiting by passing between the two heads of the pronator teres. It has a motor and sensory function in the anterior forearm and hand.

Clinical Relevance: Supracondylar Fracture A supracondylar fracture is a fracture of the distal humerus. The Gartland classification is used for these fractures: Type 1 is minimally displaced Type 2 is displaced with but with an intact posterior cortex Type 3 is completely off-ended.
