Human lumbar zygapophyseal joint inferior recess synovial folds: A light microscope examination

Abstract

The structure of human lumbar zygapophyseal joint inferior recess synovial folds as seen by high-power light microscopy is described. Small paravascular nerves and nerves unrelated to blood vessels are demonstrated in the synovial folds. Elastic fibres are demonstrated in the interlocular fibrous septa of the synovial tissue.

Reference Data for In Vivo Magnetic Resonance Imaging Properties of Meniscoids in the Cervical Zygapophyseal Joints

“…9,[15][16][17][18] In addition, anatomic studies of the lumbar spine using computed tomography and MRI have visualized meniscoids in the lumbar spine. 19 -21 Yu et al 12 were able to depict meniscoids in the cervical spine in anatomic specimens with MRI.…”

Zygapophyseal Joint Adhesions After Induced Hypomobility

“…14 Although the TMJs are modified fibrous joints and the Z joints are planar synovial joints, the same mechanism is reasonable for the Z joints, because the Z joints have an ample synovium found not only along the inner joint capsule but also surrounding the Z joint synovial folds. 20,21 Further research is required to verify the source of Z joint intra-articular ADH. Additional work characterizing the ultrastructural and biochemical composition of the ADH is also warranted.…”

Intra‐articular synovial folds of thoracolumbar junction zygapophyseal joints

“…3 3 , and 6B,C) may be a sequel to "nipping" between the articulating surfaces (Kos and Wolf, 1972). Giles (1988) has suggested that the abundance of elastic fibres demonstrated within the multilobulated synovial folds may impart a potential for elastic recoil to minimize the possibility of these synovial folds becoming trapped during normal joint movements. In a small number of cases the hyaline cartilage did not completely cover the facet surfaces, and the adjacent non-articular area was occupied by a fibroadipose synovial fold (Fig.…”
