Isolated injury of the infraspinatus branch of the suprascapular nerve.
A 30-year-old recreational baseball player developed dominant-sided infraspinatus atrophy and shoulder pain after throwing a baseball. Partial denervation of the infraspinatus muscle with delayed motor latency was documented. Isolated lesions of the branch to the infraspinatus may be more common than previously suspected, particularly in throwing athletes with shoulder pain.
