Title: An Uncommon Source of Shoulder and Upper Extremity Pain in a Collegiate Baseball Player
Developed under the guidance of Dr. Sarah Christie , Exercise Science

Quadrilateral Space Syndrome is a pathology in which the posterior humeral circumflex artery and/or axillary nerve are compressed in the quadrilateral space. Because of the vague description of pain, this syndrome is often misdiagnosed. A 21-year-old collegiate baseball player presents with left shoulder pain and numbness following practice. An MRI was ordered, which displayed a possible labral biceps pathology. Six days later, the athlete received a labral debridement, open biceps tenodesis, and subacromial decompression. However, during rehab, symptoms returned. Another MRI was ordered, which displayed nothing suspicious, and therapy was re-implemented. Two months later, the athlete saw an orthopedic surgeon, who diagnosed him with QSS.
