SR Print(0) ID 1115659942 T1 Focal Neuropathies of the Upper Extremities and Trunk: Radiculopathies, Brachial Plexopathies, and Mononeuropathies T2 Neuromuscular Disorders, 2e YR 2015 FD 2015 PB McGraw-Hill Education PP New York, NY SN 9780071752503 LK neurology.mhmedical.com/content.aspx?aid=1115659942 RD 2024/04/19 AB Numbness, pain, and/or weakness involving one or both arms are common reasons for referral to the neuromuscular clinician. These symptoms may be due to radiculopathy, brachial plexopathy, or one or more mononeuropathies. Some systemic etiologies for these focal neuropathic disorders have been discussed in preceding chapters (e.g., Lyme disease, vasculitis, and diabetes mellitus). This chapter will focus mainly on radiculopathies secondary to compression (e.g., degenerative joint disease and herniated discs), brachial plexitis, traumatic plexopathies, and focal mononeuropathies related to compression or entrapment. Before discussing the evaluation and management of these disorders, a review of the normal anatomy would be helpful.
