Abstract
|
|
|
|
The dorsal ulnar cutaneous nerve (DUCN) is the sensory branch of ulnar nerve supplying sensation to the dorsal ulnar aspect of the hand. Isolated DUCN injury is known rare. We report 3 cases of isolated DUCN injury caused by stretch injury and mild blunt injury during activities of daily living. Isolated DUCN injury may more frequently occur than we thought. Nerve conduction study and ultrasonography are useful method to localize the lesion and to evaluate the structural etiology.
