Nerve, Bone, and Joint Institute



The Nerve, Bone, and Joint Institute (NBJI) is a Washington, DC based, specialty medical practice designed to diagnose and treat neuro-musculoskeletal conditions. We aim to provide high quality comprehensive care for those suffering from pain and/or stress due to neuro-musculoskeletal medical issues. Neuro-musculoskeletal system is an integrated system of the body, intimately interconnected with body functions. Accordingly, ailments in the neuro-musculoskeletal system may also cause, contribute or exacerbate other conditions or disorders. For instance, neuro-musculoskeletal conditions can place stress on the spine and its joints, thus, affecting the nervous system and causing decreased mobility, inflammation, pain, stiffness and swelling.


Our goal at NBJI, is to evaluate patient conditions on a case-by-case basis and provide a personalized management plan for each individual. In creating the patient management plan, NBJI physicians consider a full-spectrum of treatment modalities encompassing restorative, regenerative and reconstructive options. This full-spectrum treatment approach may include non-operative, interventional and operative care. By utilizing our comprehensive and state-of-the-art approach, we strive to ensure the successful treatment of each and every patient.
