5. Interlaminar space: Synonym: interarcuate space. Space between laminae of adjacent vertebrae. Occupied by the yellow (interarcuate) ligament and medial portions of the articular process joint capsules. In dogs with degenerative lumbosacral disease, the L7-S1 interlaminar space is often narrowed. This is associated with buckling and hypertrophy of the ligaments. <Back
