A Series of Nontuberculous Mycobacterial Flexor Tenosynovitis Infections and Cost of Treatment.

 Nontuberculous mycobacteria (NTM) are rare but potentially devastating causes of musculoskeletal infection and impairment in immunocompetent patients.  Given the sparse body of literature surrounding these infections, we describe a series of patients with and the cost of treatment of upper extremity NTM infections.  In a retrospective review of seven patients with NTM infections of the upper extremity treated at a university hospital from 2010 to 2019, we assessed patient demographics, exposures, infection characteristics, management course, outcomes, and costs of treatment.
