A 21-year-old male who is training to become a professional mixed martial artist complains of weakness with forward flexion of the right arm. Four months ago, he sustained several blows and kicks to his right upper extremity, torso, and flank during consecutive training sessions. Physical exam shows the deformity shown in Figure A.

A patient presents complaining of right shoulder pain and weakness following a neck exploration surgery. On exam, he is noted to have winging of the scapula. His EMG shows denervation of the trapezius muscle. This condition is best described as:
Lateral winging due to spinal accesory nerve injury
Medial winging due to spinal accesory nerve injury
Lateral winging due to long thoracic nerve injury
Medial winging due to long thoracic nerve injury
Scapular dyskinesia due to cervical radiculopathy
Injury to the long thoracic nerve can result in which of the following clinical entities?
Teres minor atrophy
Latissimus dorsi atrophy
Medial scapular winging
Lateral scapular winging
A patient develops shoulder dysfunction and is noted to have medial winging of the scapula. If the EMG shows an abnormaility, which nerve is most likely to be involved?
A collegiate swimmer develops medial winging of the scapula. If the EMG and nerve conduction studies are abnormal, the most likely nerve roots to be involved are?
C7, C8, T1
C6, C7, C8
C5, C6, C7
C4, C5, C6
C3, C4, C5
