Incorrect description of tendons comprising the anatomic snuffbox. The article “Evaluation and Diagnosis of Wrist Pain: A Case-Based Approach” (April 15, 2013, p. 568) contained an error in the paragraph under the “Background” heading for “Case 3. De Quervain Tenosynovitis” (p. 572). The first two statements indicated that the extensor pollicis brevis and abductor pollicis longus tendons comprise the medial and lateral borders of the anatomic snuffbox. However, the lateral border of the anatomic snuffbox is actually comprised of the extensor pollicis brevis and abductor pollicis longus, and the medial border is comprised of the extensor pollicis longus. The statements should have read as follows: “Two major dorsal tendons of the thumb are involved: the extensor pollicis brevis and the abductor pollicis longus (Figure 5). These tendons comprise the lateral border of the anatomic snuffbox, with the extensor pollicis longus medially and the scaphoid bone at the bottom.” The online version of this article has been corrected.
