Lateral antebrachial cutaneous nerve (LACN) injury alone is a rare condition. Conditions such as trauma or repetitive forearm arm movements may play a role in its etiology. LACN injury may occur as a result of forceful upper extremity movements and entrapment of the LACN in the muscle tendon. In this case, a 33-year-old male solo guitarist with an LACN injury was presented. The patient stated that he often plays the guitar and is also interested in fitness. There was a sensory abnormality in the lateral right forearm without muscle weakness or pain. The compound nerve action potential of the right LACN could not be obtained. Magnetic resonance imaging and ultrasonography of the elbow and forearm revealed no abnormalities. LACN injury in this patient may be associated with forceful movements of the right forearm, including pronation, during guitar playing, and/or during fitness.
