Abstract |
Objective To evaluate the anatomic course of the lateral antebrachial cutaneous nerve (LABCN) and medial antebrachial cutaneous nerve (MABCN) in the forearm. Method We dissected 29 upper extremities of 16 cadavers for LABCN and 20 upper extremities of 15 cadavers for the MABCN. We measured the distance (BT_L) between the biceps tendon (BT) and LABCN on the intercondylar line. The BT is the point at which biceps tendon crosses intercondylar line. The distance (L12) between LABCN and the point of 12 cm distal to BT on the line between BT and radial artery at wrist was measured. The distance (ME_M) between MABCN and medial epicondyle on the intercondylar line was measured. M8 and M10 are the distances between MABCN and the points 8 cm and 10 cm distal to BT on the line from BT to mid-point of flexor carpi radialis and palmaris longus at the wrist respectively. Results BT_L and L12 were 1.4±3.7 mm and 4.4±3.7 mm respectively. ME_M, M8 and M10 were 28.6±6.9 mm, 18.9±8.9 mm and 18.3±8.2 mm respectively. The thickness of LABCN and MABCN was 19.1±4.9 mm and 13.2±4.2 mm respectively. Conclusion The LABCN was emerge just lateral to biceps tendon at the elbow and ran down to radial artery. The anatomic course of MABCN was variable at the elbow and forearm. (J Korean Acad Rehab Med 2007; 31: 329-332) |
