Craniovertebral joints


The atlantoaxial joints enable head rotation about the dens axis, whereas the atlanto-occipital joints primarily allow flexion, extension, and lateral bending. They permit flexion, extension Uncovertebral joints, also called Luschka’s joints, are seen bilaterally between adjacent cervical vertebrae, identified by the cat ear shaped uncinate processes of the C3-7 vertebrae (C1 and C2 have no uncinate processes). Craniovertebral junction 360°: A combined microscopic and endoscopic anatomical study p. The lateral facet joints of the atlas and axis limit rotation of the axis on the atlas (Shapiro et al. Craniocervical Instability (CCI), also known as the Syndrome of Occipitoatlantialaxial Hypermobility, is a structural instability of the craniocervical junction which may lead to a pathological deformation of the brainstem, upper spinal cord, and cerebellum. The atlanto-axial joint is composed of two lateral joints between the superior facets of the axis and inferior facets of the atlas and a median joint between the dens of the axis and the anterior arch and transverse ligament of atlas. Hinge joints: elbow (between the humerus and the ulna) These joints act as a door hinge does, allowing flexion and extension in just one plane Pivot joints The association of masses of the craniovertebral junction with chronic atlantoaxial subluxation raises the possibility that the underlying cause of the masses is chronic mechanical irritation. Symptoms may include pain, muscle spasm and restricted movement. Posterior view of the craniovertebral joints, showing the vertebral artery (red).

The Suárez Dissector makes possible the teaching and learning of all anatomy, from head to toe, in a rigorous, yet approachable manner. 52 It is estimated that the osseoligamentous system contributes 20% to the mechanical stability of the cervical spine while 80% Neck Instability (Craniovertebral Instability) ‘Neck instability’, ‘Craniovertebral instability’ and ‘Cervical spine instability’ are umbrella terms which cover both atlanto-axial instability and atlanto-occipital instability. However, some patients with craniovertebral injury may have no neurologic deficits . The craniovertebral complex comprises of two sets of joints-occipitoatlantal and atlantoaxial joints. Avulsion fractures in this region, associated with atlantooccipital dislocation, may be more common than previously Several studies have focused on the cartilaginous, articular, and ligamentous development of the craniovertebral joint (CVJ), but there are no unifying criteria regarding the origin and morphogenetic timetable of the structures that make up the CVJ. 25 Dissection of the craniovertebral joint ligaments Posterior view. The bony structure is designed immaculately to perform the function of circumferential mobility while being the most stable of all joints in The craniovertebral junction (CVJ) is a collective term that refers to the occiput (posterior skull base), atlas, axis, and supporting ligaments. There are many types of vertebral joints, but the atlas and axis form the only craniovertebral joints in the body. To see how a pivot joint functions www.

The drawbacks of CT include poorer evaluation of ligamentous structures. Key Points – The craniovertebral junction (CVJ) includes the base of the occiput (O), the occipital condyles, and vertebrae C1 and C2. The primary surface landmarks of the back are associated with the skull (external occipital protuberance), spine (spinous process T1, spinous process C7 and ligamentum nuchae), scapula (inferior angle, medial border, spine and acromion) and innominate (iliac crest and posterior superior iliac spine). The facet joints are relatively flat. The atlanto-occipital joints are formed between the lateral masses of the atlas (C1) and the occipital condyles of the cranium. Then the patient nods their head forward six times while stabilizing the cervical spine in only 15 degrees of anterior cranial rotation. Certain terms are conventionally used to express the anomalies, as follows. The two types of joints we are talking about are the atlanto-occipital joints and the atlanto-axial joints. Douglas L. to C-7 region. We present an extremely rare case with anomaly in the craniovertebral junction and syncope, and discuss the mechanism of the syncope. Proton weighted magnetic resonance imaging (MRI) of the craniovertebral junction, and the alar and transverse ligaments were evaluated and blinded to clinical information. The atlanto- occipital joint is a synovial joint. 4),theanterior median atlantoaxial joint(Fig. Appropriate assessment and treatment is key to resolving your pain. The median atlantoaxial joint is a pivot articulation, and the two lateral joints are gliding articulations. CRANIOVERTEBRAL JUNCTION 2. Condyloid joints occur where an egg-shaped surface of a bone fits into a concave space in another bone, allowing flexion, extension, abduction, and adduction movements ( circumduction ).

Craniovertebral Joints N15, 97-98. Dr. ; Ebrahim, M. The dynamic mechanism underlying cervical spine involvement in rheumatoid arthritis (RA) remains unidentified. Involvement of the transverse ligament leads to atlantoaxial instability (AAI). Uncovertebral joints provide permanence and direct the movement of the cervical vertebrae. ~ Recognize the symptoms and signs of lateral and medial disc codyle subluxation. The craniovertebral junction (CVJ) consists of the occiput and the first two cervical vertebrae, and functions as an articulation point capable of complex motions distinct from the remainder of the spinal column. We present one of those, the paracondylar process (PCP). Joints and Ligaments of Craniovertebral Spine. the joint between the ribs and vertebra). FIGURE 4. investigated whether narrowing of the craniovertebral and/or cervicomedullary angle (CVA, CMA) affects the trigeminal nerve branches and three upper cervical spinal nerves via stretching, thereby causing pain. These signs may also be precautionary signs for other causes of hyperrnobility. The suboccipital joints are between the skull and C1 (atlas), and between C1 and C2 (atlas and axis). *1 Assistant Professor Department of Orthopedic Physiotherapy, KLEU Institute of Physiotherapy, Belagavi, Karnataka, India. These complex joints and their articular surfaces become involved by the arthropathy, leading to ligament, joint, and bone destruction. 0 mm nodular calcification in the right alar ligament with normal adjacent bony structures.

The fact that there was a remarkable clinical im-provement following the reduction of the atlantoaxial disloca-tion and of basilar invagination, it appears that the complex As posterior approach provides adequate access with wiring technique is the poor axial stability provided to the lateral craniovertebral joints for grafting and fusion, by Hartshill rectangle or Ransford loop. Craniometric measurements used in radiologic assessment of CVJ anomalies include the Chamberlain line, Wackenheim clivus baseline, Welcher basal angle, and atlantooccipital joint axis angle. This often results in significant joint pain, along with swelling, stiffness, and reduced joint mobility. CIBA-Geigy, 1994. The upper three cervical sinuvertebral nerves (SVNs) at the craniovertebral junction (CVJ) are thought to be responsible for mediating pain from the ligaments, dura mater, and soft tissues of the posterior cranial fossa and upper cervical column.

The Therapist then places the index fingers between the occiput and spinous process of C2, so the index fingers are over the neural arch of the C1 vetebra. It also allows a pivoting motion at the atlantodental articulation, which is supported by the special ligamentous support. Potential causes of hypermobility and insta- bility in the upper cervical  The craniovertebral junction (CVJ) consists of the occipital dens axis, whereas the atlanto-occipital joints lateral masses of C2, and the atlantoaxial joints. Costovertebral Junction Definition The thoracic spine (upper back) is a very stable area of the body with little motion because it is attached to the ribs and breastbone. The atlanto-occipital joint (articulation between the atlas and the occipital bone) consists of a pair of condyloid joints. The posterior linear translation movement of the spine is prevented by Uncovertebral joints. It has a complex anatomic structure consisting of the vertebral column, paraspinal soft tissue, ligaments, and joints between the clivus, occipital bone, foramen magnum, atlas (C1), and axis (C2). the craniovertebral region of the The craniovertebral region consists of the top two joints of the neck, one on either side.

All patients were imaged with metrizamide myelography and adjunctive computed tomography (CT), then by magnetic resonance (MR) imaging. Motion at these joints may also occur in oblique planes. Plane joints (or gliding joint) carpals of the wrist, acromioclavicular joint: These joints allow only gliding or sliding movements, are multi-axial such as the articulation between vertebrae. Vertebral artery injury or cranial nerve deficits may be present. The craniovertebral joints include: Atlanto-occipital CRANIOVERTEBRAL JUNCTION The craniovertebral (or craniocervical) junction(CVJ) is a collective term that refers to the occiput (posterior skull base), atlas, axis, and supporting ligaments.

Thus condyloid joints are biaxial. Asked in Human Anatomy and Physiology Craniovertebral joints: they are synovial joints with no IV discs. It encloses the soft tissue structures of the cervicomedullary junction which includes medulla, spinal cord and lower cranial nerves. Tamarkin, of Springfield Technical Community College states that pivot joint action occurs when one bone spins around on another in either the left or the right direction. Anatomy The biomechanical features of the CVJ arise from the unique characteristics of the structures that comprise this region. Whilst occipitoatlantal joint is the most stable, atlantoaxial is the most mobile of all joints of the body. It includes some ligaments and membranes such as the alar ligament, cruciform ligament, apical ligament, atlantoaxial accessory, capsular joints, tectorial membrane (TM Introduction The craniovertebral region is an area of the spine with a high level of variability.
