The midline interlaminar ligament of the spine: An anatomical study

Abstract

Introduction: During routine cadaveric dissection, Simonds et al. in 2019 found a previously undocumented ligament, which they termed the midline interlaminar ligament (MIL), in 24 out of 36 (76.5%) lumbar spinal levels. The MIL is an unpaired ligament located between and distinctly separate from the right and left ligamenta flava (LF).The purpose of this study was to identify the presence or absence of the MIL in the cervical, thoracic, and lumbar spinal regions and obtain detailed measurements of the ligaments' toughness (R) and elastic modulus (E).Materials and Methods: Intact preserved cadaveric vertebrae from C2 to the upper sacral region were dissected. Presence or absence of the MIL was documented, and length and width of each MIL were measured in situ. The R and E of the LFs from corresponding spinal segments were found for comparison.Results: At least one MIL was observed in 90.3% (28) of specimens. Eighty-eight MIL's were observed out of 186 cervical intervertebral levels (0.5%), 371 thoracic intervertebral levels (5.9%), and 101 lumbar intervertebral levels (63.4%). The mean width and

“…A majority of Fellows are successful in publishing within a peer‐reviewed journal. As such, past Fellows have successfully published in Clinical Anatomy (Bancroft & Stephens, 2007; Telisky & Olinger, 2011; Dahlstrom & Olinger, 2014; Mayer et al, 2019; Millhuff et al, 2023), Orthopaedic Journal of Sports Medicine (Daggett et al, 2017; Johnson et al, 2022), Surgical and Radiological Anatomy (Woyski et al, 2013; Smith et al, 2017), Aesthetic Surgical Journal (Marolt et al, 2021; Moorefield et al, 2021; Freed et al, 2022), and Medical Educator (Motzko & Dennis, 2023; Stock & Singh, 2023); however, this is not an exhaustive list. To support research endeavors, Fellows are allotted $1500 to cover the costs associated with attending research conferences and other activities related to professional development.…”
