Early division of median nerve is noted proximal to carpal tunnel.
( Cross sectional area of radial division - 0.8 mm2 ; Cross sectional area of ulnar division - 0.9 mm2 ; Combined cross sectional area - 17 mm2 )
Case Discussion
Combine cross sectional area > 11 mm2 is considered abnormal and compatible with carpal tunnel syndrome in a case of bifid median nerve.
