Intrathecal Fentanyl Pump Placement in a Patient With Chronic Pain Caused by Hereditary Multiple Exostoses: A Case Report.

Hereditary multiple exostoses (HME) is a genetic disorder defined by the formation of benign bone tumors known as exostoses, which can lead to chronic pain and functional impairment. This case report details a 57-year-old man with a long-standing history of severe diffuse bone pain attributed to HME. Despite various treatments, his pain remained poorly controlled until an intrathecal pump with fentanyl was implanted. This intervention significantly improved his pain management and overall quality of life. The manuscript explores clinical presentation, diagnostic approach, and treatment outcomes, highlighting the challenges and benefits of intrathecal drug delivery systems in managing refractory pain associated with HME.
