Abstract
|
|
|
The intercostobrachial nerve (ICBN) originates from the second intercostal nerve’s lateral cutaneous branch, whilethe median nerve (MN) typically arises from the brachial plexus’s lateral and medial roots. The medial cutaneous nerve of thearm, a branch of the medial cord of the brachial plexus, often connects with the ICBN. Variations were observed during thedissection of a 50-year-old male cadaver, including MN having two lateral roots (LR), LR1 and LR2, joining at different levels.
Three ICBNs innervated the arm in this case, with the absence of the medial cutaneous nerve of the arm compensated bybranches from the medial cutaneous nerve of the forearm. Understanding these anatomical variations is crucial for surgicalprocedures like brachioplasty, breast augmentation, axillary lymph node dissection, and orthopedic surgery. Surgeons andmedical professionals must be aware of these variations to enhance preoperative planning, minimize complications, andimprove patient outcomes in these procedures.
