MS-3262

A basketball enthusiast in his early twenties visits his GP complaining of discomfort in his right shoulder and neck, and also reports an unusual appearance on the right side of his upper back.

To assess the condition, the GP asks the patient to stand facing a wall and extend his arms straight in front of him, with his palms flat against the wall. The GP then instructs the patient to bend his arms and push away from the wall. During the movement, the patient’s right shoulder blade protrudes from his back.

Based on the symptoms, which nerve is most likely to be affected?
