Origin of the uncus and of Luschkaʼs joint in the cervical spine.

Strain rate dependent properties of younger human cervical spine ligaments

“…The spaces between the vertebral bodies from C3 to C6 have a unique feature called uncovertebral joints, or Luschka's joints (Hayashi et al, 1985). They exist between the bony lips that project from the superior vertebral body inferiorly, toward the bony lips, also known as uncinate processes, that project superior from the inferior vertebral body (Moore et al, 1999).…”

Resection or degeneration of uncovertebral joints altered the segmental kinematics and load-sharing pattern of subaxial cervical spine: A biomechanical investigation using a C2–T1 finite element model

“…The UJ consists of uncinate processes and corresponding beveled surfaces on the inferior aspect of adjacent superior vertebrae. Uncinate processes are bony protuberances that extend cranially from the lateral margins of C3 (the third cervical vertebra) to C7, and occasionally at T1 and T2, and form the medial wall of the intervertebral foramen (IVF) in the SCS (Hayashi and Yabuki, 1985).…”

Courses of Cervical Disc Herniation Causing Myelopathy or Radiculopathy

“…5 They have an uncinate process projecting upward from the lateral margin to the lateral one fifth of the posterior margin of the vertebral body, forming the socalled joint space with the upper adjacent body. The joint space contains fibrocartilagenous fiber and narrows with sclerosis and osteophyte formation in the process of degeneration.…”
