The brachial plexus instead lies in the tissue plane between the rigid anatomical structures that form the boundaries of the anatomical axilla.17This rigid anatomy and the tissue plane within its borders combine to contain and direct the flow of an injected solution. The LAC and MAC nerve blocks can provide either primary anesthesia for superficial forearm operations or supplement an incomplete plexus block. Cite this article. This nerve involvement was also reported with tuberculoid leprosy neuritis [10] and subcutaneous lipoma [11]. Anesthetizing the skin of the medial forearm requires block of the MAC nerve, not the ulnar nerve at the elbow. Semantic Scholar is a free, AI-powered research tool for scientific literature, based at the Allen Institute for AI.

Either a motor response that consists of wrist flexion and/or thumb opposition or a paresthesia to the thumb or index finger is sought before injecting 35 mL of local anesthetic. The nerve blocks also represent a reasonable alternative for supplementation when proximal brachial plexus block is incomplete. Antebrachium The medial antebrachial cutaneous nerve of the forearm (MAC) is an intermediary branch of the medial cord. FIGURE 7. From where these two lines cross, the suprascapular notch underlies a point approximately 23 cm toward the middle of the upper/outer quadrant (see Figure 5). PubMedGoogle Scholar. The suprascapular nerve (C4C5) branches from the superior trunk of the brachial plexus and, therefore, it is usually anesthetized by an interscalene block. Careers. Quizlet It provides cutaneous innervation to the medial (ulnar) half of the volar forearm, an area commonly misperceived as innervated by the ulnar nerve (see Figures 1 and 2). The medial antebrachial cutaneous nerve originates from the medial cord of the brachial plexus in continuation of the lower trunk. Along with the medial cutaneous nerve of the arm (an intermediary branch of the medial cord), the intercostobrachial nerve provides cutaneous sensation to the upper half of the medial/posterior arm. 8600 Rockville Pike After 2days, the nature of the pain became dull. Numbness and sensory complaints of the medial side of the right hand and fifth finger showed improvement, but the sensory disturbance remained at the medial side of the forearm until 6months follow-up.
