Calcified Tendinitis of the Flexor Carpi Ulnaris Tendon: A Case Report

INTRODUCTION: Calcification in the tendon (Calcific Tendinitis) occurs commonly in the shoulder, but this condition can happen in other tendon sites. Calcific tendinitis of the hand and wrist occurs rarely, which causes unfamiliarity toward the disease. With the symptoms mimicking other causes, misdiagnosis often happens. This can cause ineffective and over treatment. CASE REPORT: A 51-year-old man presented with a 2-week-pain on his right wrist with localized erythema and tenderness on physical examination. Imaging with ultrasound and X-ray shows calcification on the flexor carpi ulnaris tendon. Patient was treated with splinting for 2 weeks and NSAID for pain management and was free of pain afterwards. CONCLUSION: Calcific tendinitis mimics the symptoms of various causes. The ability to differentiate this entity to other differential diagnosis leads to an effective and precise treatment.
