Variant Distal Ulnar Nerve Loop: A Previously Undescribed Anatomical Finding.
Cureus. 2018 May 10;10(5):e2604. doi: 10.7759/cureus.2604.
Abstract
A previously undescribed variant ulnar nerve loop was discovered during the routine anatomic forearm and hand dissection of an adult female. The major finding was that of a large loop traveling around the distal tendon of the flexor carpi ulnaris. The variation presented here appears to be unique. The exact function of such derailed anatomy is not clear but, if found during surgery, might confound normal dissection methods or, when present, could result in varied clinical presentations regarding the sensory or motor examination of the hand.
