The cubital fossa, antecubital fossa, chelidon, or inside of elbow is the area on the anterior side of the upper part between the arm and forearm of a human or other hominid animals. It lies anteriorly to the elbow (antecubital) (Latin cubitus) when in standard anatomical position. The cubital fossa is a triangular area having three borders. [1]
Ulnar nerve is most commonly injured in the flexion type of injury because it crosses the elbow below the medial epidcondyle of the humerus. [ 3 ] A puckered, dimple, or an ecchymosis of the skin just anterior to the distal humerus is a sign of difficult reduction because the proximal fragment may have already penetrated the brachialis muscle ...
At the midshaft of the humerus, the radial nerve travels from the posterior to the anterior aspect of the bone in the spiral groove. A fracture of the humerus in this region can result in radial nerve injury. The ulnar nerve lies at the distal end of the humerus near the elbow. When struck, it can cause a distinct tingling sensation, and ...
Elbow dislocations constitute 10% to 25% of all injuries to the elbow. The elbow is one of the most commonly dislocated joints in the body, with an average annual incidence of acute dislocation of 6 per 100,000 persons. [30] Among injuries to the upper extremity, dislocation of the elbow is second only to a dislocated shoulder. A full ...
Ulnar neuropathy at the cubital tunnel is diagnosed based on characteristic symptoms and signs. Intermittent or static numbness in the small finger and ulnar half of the ring finger, weakness or atrophy of the first dorsal interosseous, positive Tinel sign over the ulnar nerve proximal to the cubital tunnel, and positive elbow flexion test (elicitation of paresthesia in the small and ring ...
Dislocated shoulder; Anterior dislocation of the left shoulder. Specialty: Emergency medicine, orthopedics: Symptoms: Shoulder pain: Complications: Bankart lesion, Hill-Sachs lesion, rotator cuff tear, axillary nerve injury [1] Types: Anterior, posterior, inferior, superior [2] [1] Causes: Fall onto an outstretched arm or the shoulder. [3 ...
The brachialis (brachialis anticus) is a muscle in the upper arm that flexes the elbow. It lies beneath the biceps brachii, and makes up part of the floor of the region known as the cubital fossa (elbow pit). It originates from the anterior aspect of the distal humerus; [1] it inserts onto the tuberosity of the ulna.
It gives branches to the muscles of the anterior compartment. The artery is in between the median nerve and the tendon of the biceps muscle in the cubital fossa. It then continues into the forearm. The deep artery of the arm travels through the lower triangular space with the radial nerve. From here onwards it has an intimate relationship with ...
