Analysis of Migration Patterns of Disk Fragments and Contributing Factors in Extruded Lumbar Disk Herniation  Eun-Seok Son, MD, PhD, Du Hwan Kim, MD, Jae Won Jung, MD, Donggyu Lee, MD  PM&R  Volume 9, Issue 1, Pages (January 2017) DOI: /j.pmrj Copyright © 2017 American Academy of Physical Medicine and Rehabilitation Terms and Conditions

2 Figure 1 Axial views of lumbar spine magnetic resonance imaging in patients with extruded lumbar disk herniation. Central (A), paracentral (B), subarticular (C), and foraminal (D) migration of herniated disk materials in the horizontal plane. PM&R 2017 9, 15-20DOI: ( /j.pmrj ) Copyright © 2017 American Academy of Physical Medicine and Rehabilitation Terms and Conditions

3 Figure 2 Sagittal view of lumbar spine magnetic resonance imaging in patients with extruded lumbar disk herniation. Rostral (A) and caudal (B) migration of herniated disk materials in the vertical plane. PM&R 2017 9, 15-20DOI: ( /j.pmrj ) Copyright © 2017 American Academy of Physical Medicine and Rehabilitation Terms and Conditions

4 Figure 3 Association between migration in the vertical plane and age. A significant increase was observed in the number of rostral migration cases with increasing age (P = .048).

5 Figure 4 Association between migration in the horizontal plane and age. A significant association was found between migration in the horizontal plane and increasing age (P = .010). PM&R 2017 9, 15-20DOI: ( /j.pmrj ) Copyright © 2017 American Academy of Physical Medicine and Rehabilitation Terms and Conditions

6 Figure 5 Association between migration in the horizontal plane and vertical plane. A significant association was found between migration in the vertical and horizontal planes; all patients with foraminal herniation had rostral migration (P < .001).
