Recalcitrant Ulnar-Sided Hand Pain in a Collegiate Golfer: A Case Report.

This case report details a diagnosis of myositis ossificans in a collegiate golfer with right ulnar-sided hand pain after striking the ground on a swing. Despite conservative treatment and a thorough workup, the patient's ulnar-sided hand pain did not improve. An ultrasound eventually revealed myositis ossificans within the abductor digiti minimi muscle. The patient received an ultrasound-guided fenestration and injection of lidocaine and dexamethasone into the affected muscle, leading to complete symptom resolution. Myositis ossificans is often secondary to trauma, causing bone formation in soft tissue, leading to pain, limited range of motion, and disability. This case highlights the importance of considering myositis ossificans in cases of persistent muscular pain and the diagnostic challenges related to ulnar-sided hand anatomy.
