Arthroscopic shoulder surgery for gouty long head of biceps tendinitis: a case report.

Objective: The objective of the case report is to analyze the clinical manifestations and imaging features of gouty long head of biceps tendinitis, and to summarize the methods and effects of shoulder arthroscopic surgery.

Clinical presentation and intervention: The clinical data of a 39-year-old Han Chinese female with gouty long head of the biceps tendinitis was retrospectively analyzed, and the clinical manifestations, imaging features, and diagnosis and treatment were analyzed. The patient presented with pain and limited movement of right shoulder joint. Computed tomography showed irregular high-density shadows above the glenoid and adjacent to the coracoid process of the right shoulder. Magnetic resonance imaging revealed superior labrum anterior and posterior injury with edema in the upper recess and axillary sac. After arthroscopic surgery, the "tofu residue" tissue of the long head of the biceps was removed, and the postoperative pathological examination proved that it was gout stone.

Conclusion: Gouty long head of the biceps tendinitis is a rare disease. Arthroscopic surgery can probe the structural lesions of shoulder cavity in all aspects, improve the surgical accuracy, and reduce the trauma.
