What is the Uncinate?
Introduction. The uncinate process is a hook like extension from the lower part of the head of the pancreas, and it extends superiorly and posteriorly behind the superior mesenteric vein (SMV), and ends either to the right side or extending behind the superior mesenteric artery (SMA) 1.
Where is the Uncinate located?
The uncinate processes refer to a hook-shaped process, or bony protuberance, located on the lateral or posterolateral margins of the superior endplates of the cervical vertebral bodies, most commonly found at the levels of C3-C7.
What is Uncinate joint?
The uncinate processes refer to a hook-shaped process, or bony protuberance, located on the lateral or posterolateral margins of the superior endplates of the cervical vertebral bodies, most commonly found at the levels of C3-C7 [2].
What is the main cause of spondylosis?
The main cause is aging, but the way aging affects your spine can lead to other changes and problems. Spondylosis is a cascade: One anatomical change occurs, which leads to more degeneration and changes in your spine’s structures. These changes combine to cause spondylosis and its symptoms.
What does the uncinate process do?
The uncinate process is one of the unique features of the cervical vertebrae. Uncinectomy and uncoforaminotomy are widely used to decompress the nerve in the intervertebral foramen and to remove osteophytes from the uncinate process.
Whats in the uncinate process?
An uncinate process is a hook-shaped projection or protuberance from a bone or organ. It may refer to: Uncinate process of ethmoid bone, a process located in the nasal cavity. Uncinate processes of ribs, separate bones or projections from ribs.
Is uncinate process a bone?
The uncinate process is one of the three downward vertical projections of the ethmoid bone (the other two are the perpendicular plate and the middle turbinate) and articulates inferiorly with the ethmoid process of the inferior turbinate (Figure IB).
What are the uncinate processes in the cervical spine?
The uncinate process of the cervical spine is a hook-shaped process found bilaterally on the superolateral margin of the cervical vertebral bodies of C3-C7. The uncinate processes are more anteriorly positioned in the upper cervical spine and more posteriorly location in the lower cervical spine.
Which organ has an uncinate process?
Anatomical terminology The uncinate process is a small part of the pancreas. The uncinate process is the formed prolongation of the angle of junction of the lower and left lateral borders in the head of the pancreas. The word “uncinate” comes from the Latin “uncinatus”, meaning “hooked”.

Where are uncinates located in the cervical spine?
The uncinates or uncovertebral joints are joints only found in the part of the spine that is in the neck (the cervical spine). When the uncinates hypertrophy, that means that they have gotten bigger.
Which is part of the rib has uncinate process?
The ribs have capitula and tubercula, and often uncinate processes (see p. 190) as in birds. From near the distal end an imperfectly ossified uncinate process (see p. 190) projects backwards. Projecting backwards from each is a large hooked uncinate process.
