- The facet joints, (or zygapophysial joints, zygapophyseal, apophyseal, or Z-joints) are a set of synovial, plane joints between the articular processes of two adjacent vertebrae.
- The Facet Joints, also known as the Zygapophyseal Joints, are located closer to the back of the spine, where they project above and below the vertebral arch.
- These joints also allow for movement of the spine, as well as providing for stability of the overall structure.
- Synarthroses are called as Fixed Joints.
- A type of joint which permits very little or no movement under normal conditions.
- The knee joint is classified as a synovial joint.
- The knee falls under the uniaxial as it is a hinge joint and it moves in one plane with slight rotational movement, but the rotation is not enough to be considered significant.
- Cubitus valgus is a medical deformity in which the forearm is angled away from the body to a greater degree than normal when fully extended.
- A small degree of cubitus valgus (known as the carrying angle) is acceptable and occurs in the general population.
- Cubitus varus (varus means a deformity of a limb in which part of it is deviated towards the midline of the body) is a common deformity in which the extended forearm is deviated towards midline of the body.
- Cubitus varus is often referred to as “Gunstock deformity”, due to the crooked nature of the healing.
- When your arms are held out at your sides and your palms are facing forward, your forearm and hands should normally be about 5 to 15 degrees away from your body. This is the normal “carrying angle” of the elbow.
- This angle allows your forearms to clear your hips when you swing your arms, such as during walking.
- The quadratus lumborum contributes to the stabilization and movement of the spine and the pelvis.
- A bilateral contraction leads to an extension of the lumbar vertebral column. When the muscle is only activated on one side, the trunk is bent towards that direction (lateral flexion).
