Incorrect anatomy. The article “Cervical Radiculopathy: Nonoperative Management of Neck Pain and Radicular Symptoms” (January 1, 2010, p. 33) incorrectly labeled the disk interspaces for nerve roots C8 and T1 in Table 1 (p. 35). Because there is not a C8 vertebral body, the Interspace column of Table 1 should have listed C7-T1 rather than C7-C8 for nerve root C8, and T1-T2 rather than C8-T1 for nerve root T1. This table was adapted with permission in Table 2 (p. 748) of the article “Nonoperative Management of Cervical Radiculopathy” (May 1, 2016, p. 746), and the errors from Table 1 in the 2010 article were repeated. The online versions of these articles have been corrected.
