%X The anatomy of the lateral antebrachial cutaneous nerve is relevant in the clinical and surgical medical knowledge. Its lesion may be doing by nerve entrapment, needle procedures, trauma, among others. The objectives of this study are to establish the anatomical elements that may participate in the nerve entrapment and to establish anatomical landmarks to localize the nerve at the elbow. We have dissected 20 upper limbs (12 left, 8 right) exploring the lateral bicipital canal, focusing in the anatomical relations of the musculocutaneous nerve and the lateral antebrachial cutaneous nerve. The tendon of the biceps has an extensive and sharp lateral edge. The lateral antebrachial cutaneous nerve passes beneath the tendon. A muscle-aponeurotic tunnel was observed at the lateral bicipital region. This tunnel may support the contact between the nerve and the biceps tendon. The results of the measurements show the nerve has a extensive contact between the lateral antebrachial cutaneous nerve and biceps tendon. The results of this research support the use of the biceps tendon as landmark to localize the lateral antebrachial cutaneous nerve at the elbow.
