Erratum to: Controlled Motion with the XL-TDR Lateral-Approach Lumbar Total Disk Replacement: In Vitro Kinematic Investigation (J Neurol Surg A Cent Eur Neurosurg 2015;76(2):133–138)

It has been brought to the Publisher's attention that there is an error in [Fig. 2] of the above mentioned article, published in Journal of Neurological Surgery-Part A, Volume 76, Number 2, 2015, page 135 (DOI: 10.1055/s-0034-1394187). The bottom and the middle fluoroscopic images of Fig. 2 are swapped around.

The correct figure appears below.

Fig. 2 Representative photographs and lateral fluoroscopy images of specimens utilized in the nondestructive multidirectional (flexionextension, left-right lateral bending, and left-right axial rotation) testing. Test conditions were (A) intact spine, (B) XL-TDR at L4–L5 with intact anterior annulus/ligament, (C) XL-TDR at L4–L5 with resection of the anterior annulus/ligament.
