“…In the cubital fossa, the median nerve lies medial to the brachial artery, deep to the bicipital aponeurosis and anterior to the brachialis muscle [2-3]. We found this nerve to lie an average of three centimeters lateral to the medial epicondyle.…”

“…It is closely related to the brachial artery throughout its course in the arm [3]. It then enters the forearm between the heads of the pronator teres [3]. The median nerve innervates the palmar skin of the thumb, index and middle fingers and the lateral side of the ring finger and provides innervation to most of the flexor compartment of the forearm.…”

“…The radial nerve at the elbow lies in the deep groove between the brachialis medially and the brachioradialis and extensor carpi radialis longus, laterally [2-3]. It provides innervation to the extensors of the forearm and innervates the skin of the lower lateral arm, the posterior aspect of the forearm and the skin over the dorsum of the radial half of the ring, middle, and index fingers and the thumb [2].…”

IntroductionThe median and radial nerves are two important neural structures found in the cubital fossa. The trajectory and landmarks used to identify their location are important when procedures are done in this area.Methods and materialsTen fresh-frozen cadavers were dissected (20 upper limbs) and measurements were taken from the medial epicondyle to the median and radial nerves as well as to the lateral epicondyle of each limb.ResultsThe distance between the medial epicondyle and the median nerve was found to be three centimeters with a range of 2.1 to four centimeters and the distance from the medial epicondyle to the radial nerve had a mean distance of 5.5 cm and a range of 3.8 to seven centimeters.DiscussionDamage to the median or radial nerves can lead to major complications including loss of extension, flexion, and sensation in the forearm and hand. Other studies have tried to identify the course of these nerves in order to prevent their injury during procedures.ConclusionAfter identifying the medial epicondyle, using the results we obtained, physicians may have a better understanding of where the median and radial nerves lie within the cubital fossa when performing procedures in this area.

The elbow is a complex joint made up of three separate articulations within a common capsule. The proximal ulna articulates with the trochlea and functions as a hinge joint, while the proximal radioulnar joint provides for rotational movement of the forearm. The radiocapitellar joint allows for both hinge and rotational movements. Together, these allow for flexion and extension of the arm and, in conjunction with the distal radioulnar joint at the wrist, pronation and supination as well.
