Spine (neck and back) disorders

Arachnoiditis is an inflammatory response of the arachnoid, one of three coverings, or meninges, that envelop the brain and spinal cord. Arachnoiditis is a general term for several progressive regional disorders all of which result in the inflammation of parts of the middle membrane surrounding the spinal cord and brain and the space defined by this membrane (subarachnoid space).
Neck pain
Neck pain is pain that occurs anywhere from the bottom of your head to the top of your shoulders. It may spread to the upper back or arms and may cause limited neck and head movement. Common neck pain is from muscle strain or tension. Individuals with minor neck pain may be experiencing the earliest symptoms of arthritis.
Whiplash is an injury to the neck caused by the neck bending forcibly forward and then backward, or vice versa. The injury usually involves the muscles, discs, nerves, and tendons in the neck. Whiplash occurs when the neck is suddenly and forcibly bent backward and forward. This causes injury to the joints of the neck, known as the cervical vertebrae, and to the surrounding soft tissue.
Herniated disc
A herniated disc is a common cause of lower back pain. Disks are round, flat, plate-like structures between the vertebrae (back bones) in the spinal column. They have a tough covering over a soft, gelatinous inside (nucleus pulposus), and their purpose is to cushion the back bones and allow the back to flex. A hernia is a tear in the covering of the disc that allows the soft interior to bulge out.
Kyphosis is the extreme curvature of the upper back also known as a hunchback. Kyphosis is a spinal deformity that can result from trauma, developmental problems, or degenerative disease. Kyphosis can occur at any age, although it is rare at birth. Kyphosis is a flexed curvature of the spine in a sagittal plane, as is present normally in the thoracic and sacral regions.
Lordosis is an increased curvature of the normally curved lumbar spine. Lordosis is a curve in the spine in a sagittal plane, convexity forwards. A certain amount of lordosis is normal in the lumbar and cervical regions of the spine. Loss of the normal lumbar lordosis may be a sign of ankylosing spondylitis or paravertebal muscle spasm. Also known as swayback.
Scoliosis is a lateral curvature of the spine. In most cases this curvature develops during childhood and adolescence. The spinal column curves and twists, rotating the rib cage as it does so and eventually causes changes to the spine, chest and pelvis. A slight curve of the spine is a common condition. Scoliosis may result from a birth defect or develop later in life, most often in adolescence.
Spinal stenosis
Spinal stenosis is narrowing of the spinal canal caused by excessive growth of bone and/or thickening of tissue, which reduces the size of the openings in the spinal bones (vertebrae). This narrowing can squeeze and irritate the spinal nerve roots where they leave the spinal cord or the spinal cord itself. The disease and its effects are similar to stenosis in the lower spine.
Torticollis (cervical dystonia or spasmodic torticollis) is a type of movement disorder, in which the muscles controlling the neck cause sustained twisting or frequent jerking. Torticollis may cause permanent facial deformity if it is not resolved in the first year. Torticollis may occur without known cause (idiopathic), be genetic (inherited), or be acquired secondary to damage to the nervous system or muscles.
Back pain
Back pain is one of humanity's most frequent complaints and does not usually reflect any underlying disease. The most common type of back pain is lower back pain. That's because the lower portion of the back is under the most pressure when a person is sitting or lifting, and it can be easily damaged. Lower back pain is often triggered by some combination of overuse, muscle strain, or injury to the muscles and ligaments that support the spine.
