The joint that occurs between facets of the interior and superior articular processes of adjacent VERTEBRAE.
Mechanical compression of nerves or nerve roots from internal or external causes. These may result in a conduction block to nerve impulses (due to MYELIN SHEATH dysfunction) or axonal loss. The nerve and nerve sheath injuries may be caused by ISCHEMIA; INFLAMMATION; or a direct mechanical effect.
Diseases of the twelfth cranial (hypoglossal) nerve or nuclei. The nuclei and fascicles of the nerve are located in the medulla, and the nerve exits the skull via the hypoglossal foramen and innervates the muscles of the tongue. Lower brain stem diseases, including ischemia and MOTOR NEURON DISEASES may affect the nuclei or nerve fascicles. The nerve may also be injured by diseases of the posterior fossa or skull base. Clinical manifestations include unilateral weakness of tongue musculature and lingual dysarthria, with deviation of the tongue towards the side of weakness upon attempted protrusion.
A surgical procedure that entails removing all (laminectomy) or part (laminotomy) of selected vertebral lamina to relieve pressure on the SPINAL CORD and/or SPINAL NERVE ROOTS. Vertebral lamina is the thin flattened posterior wall of vertebral arch that forms the vertebral foramen through which pass the spinal cord and nerve roots.
VERTEBRAE in the region of the lower BACK below the THORACIC VERTEBRAE and above the SACRAL VERTEBRAE.
Acute and chronic conditions characterized by external mechanical compression of the SPINAL CORD due to extramedullary neoplasm; EPIDURAL ABSCESS; SPINAL FRACTURES; bony deformities of the vertebral bodies; and other conditions.

General term for CYSTS and cystic diseases of the OVARY.
Paired bundles of NERVE FIBERS entering and leaving the SPINAL CORD at each segment. The dorsal and ventral nerve roots join to form the mixed segmental spinal nerves. The dorsal roots are generally afferent, formed by the central projections of the spinal (dorsal root) ganglia sensory cells, and the ventral roots are efferent, comprising the axons of spinal motor and PREGANGLIONIC AUTONOMIC FIBERS.
Forward displacement of a superior vertebral body over the vertebral body below.
Intradermal or subcutaneous saclike structure, the wall of which is stratified epithelium containing keratohyalin granules.
Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.

Cervical synovial cysts: case report and review of the literature. (3/77)

The authors describe the case of a 58-year-old man with a 6-month history of severe myelopathy. CT scan and MRI of the spine revealed a cystic formation, measuring about 1 cm in diameter, at C7-T1 at a right posterolateral site at the level of the articular facet. At operation the mass appeared to originate from the ligamentum flavum at the level of the articular facet and was in contact with the dura mater. Once the mass had been removed, there was a significant amelioration of the patient's symptoms. As previously suspected, histological aspect was synovial cyst. Cervical synovial cysts are extremely rare and, as far as we know, only 22 cases have so far been described in the literature. Diagnostic radiological investigations used were CT scan and MRI. At CT scan the most important diagnostic findings are a posterolateral juxtafacet location of the mass, egg-shell calcifications on the wall of the cyst, and air inside the cyst. At MRI the contents of the cyst are iso/hypointense on T1- and hyperintense on T2-weighted images. There may also be a hypointense rim on T2-weighted images, which enhances after i.v. administration of gadolinium. Surgical treatment consists of removal of the mass. Fixation of the vertebral segments involved is not always necessary.  (+info)

Craniocervical junction synovial cyst associated with atlanto-axial dislocation--case report. (4/77)

A 51-year-old female presented with a rare case of synovial cyst at the cruciate ligament of the odontoid process associated with atlanto-axial dislocation, manifesting as a history of headache and numbness in her left extremities for 5 months, and progressive motor weakness of her left leg. Neuroimaging studies revealed a small cystic lesion behind the dens, which severely compressed the upper cervical cord, and atlanto-axial dislocation. The cyst was successfully removed via the transcondylar approach. C-1 laminectomy and foramen magnum decompression were also performed. Posterior craniocervical fusion was carried out to stabilize the atlanto-axial dislocation. The cyst contained mucinous material. Histological examination detected synovial cells lining the fibrocartilaginous capsule. Synovial cysts of this region do not have typical symptoms or characteristic radiographic features. Careful preoperative evaluation of the symptoms and a less invasive strategy for removal of the cyst are recommended.  (+info)

Alternative and effective treatment of shoulder ganglion cyst: ultrasonographically guided aspiration. (5/77)

The therapeutic effect of ultrasonographically guided aspiration of a ganglion cyst of the shoulder is evaluated. Fifteen patients (nine male, six female) with chronic shoulder pain were enrolled in this study. Each patient was referred to rule out rotator cuff lesion. The ultrasonographic examination showed an anechoic cystic lesion in the shoulder region in every patient and abnormality of the rotator cuff in only four patients. Under ultrasonographic guidance, an 18 gauge needle was inserted into the cyst to aspirate the fluid. Initial sonographic imaging showed the cyst, which appeared as a localized fluid accumulation and was located between the deltoid muscle and the subscapularis tendon in seven patients, between the deltoid muscle and the biceps tendon in one patient, below the coracoacromial ligament in five patients, and over suprascapular notch area in one patient. The ganglion cysts ranged in size from 3.5 to 30 mm. The amount of aspirated fluid in each cyst varied from 0.4 to 12 ml (mean, 2.6 ml +/- 3.1) with a clear or light yellowish color and a jelly-like appearance. No major complications occurred during or after this procedure. The symptom (pain) was improved after sonographically guided aspiration in each patient. Follow-up study showed complete relief of pain in four patients, marked improvement in nine patients, and mild improvement but still persistent shoulder pain in two patients. Duration of follow-up study ranged from 2 to 24 months (mean, 6.4 months +/- 6.9). The success rate for sonographically guided aspiration was 86% on the basis of marked symptom improvement or relief. Ultrasonographically guided aspiration of shoulder ganglion cysts is an effective procedure in the management of shoulder pain caused by ganglion cysts.  (+info)

Spontaneous remission of a solitary intraspinal synovial cyst of the lumbar spine. (7/77)

We report on a 15-year-old boy in whom a spontaneous remission of a symptomatic synovial cyst, possibly emanating from the L4-5 facet joint, was noted. The medical history suggested that sport-related overactivity and/or minor trauma was the underlying cause. Conservative treatment for several months may be one treatment option if the cyst wall is not calcified and the symptoms and signs related to radiculopathy show a gradual decrease.  (+info)

Use of magnetic resonance imaging to diagnose common wrist disorders. (8/77)

Magnetic resonance imaging is being used more frequently to diagnose and plan treatment of wrist disorders. This article reviews the common pathologic lesions of the wrist: avascular necrosis, triangular fibrocartilage complex tears, ligamentous tears, ganglion cysts, carpal tunnel syndrome, and osteoarthritis. The typical magnetic resonance imaging characteristics of these lesions is discussed.  (+info)

A Synovial Cyst is a type of benign cyst that typically develops in the synovium, which is the membrane that lines and lubricates joint capsules. These cysts are filled with synovial fluid, which is the same lubricating fluid found inside joints. They usually form as a result of degenerative changes, trauma, or underlying joint diseases such as osteoarthritis.

Synovial cysts commonly occur in the spine (particularly in the facet joints), but they can also develop in other areas of the body, including the knees, hips, and hands. While synovial cysts are generally not harmful, they may cause discomfort or pain if they press on nearby nerves or restrict movement in the affected joint. Treatment options for synovial cysts range from conservative measures like physical therapy and pain management to surgical intervention in severe cases.

A cyst is a closed sac, having a distinct membrane and division between the sac and its surrounding tissue, that contains fluid, air, or semisolid material. Cysts can occur in various parts of the body, including the skin, internal organs, and bones. They can be caused by various factors, such as infection, genetic predisposition, or blockage of a duct or gland. Some cysts may cause symptoms, such as pain or discomfort, while others may not cause any symptoms at all. Treatment for cysts depends on the type and location of the cyst, as well as whether it is causing any problems. Some cysts may go away on their own, while others may need to be drained or removed through a surgical procedure.

Polyradiculopathy is a medical term that refers to a condition affecting multiple nerve roots. It's a type of neurological disorder where there is damage or injury to the nerve roots, which are the beginning portions of nerves as they exit the spinal cord. This damage can result in various symptoms such as weakness, numbness, tingling, and pain in the affected areas of the body, depending on the specific nerves involved.

Polyradiculopathy can be caused by a variety of factors, including trauma, infection, inflammation, compression, or degenerative changes in the spine. Some common causes include spinal cord tumors, herniated discs, spinal stenosis, and autoimmune disorders such as Guillain-Barre syndrome.

Diagnosing polyradiculopathy typically involves a thorough neurological examination, imaging studies such as MRI or CT scans, and sometimes nerve conduction studies or electromyography (EMG) to assess the function of the affected nerves. Treatment for polyradiculopathy depends on the underlying cause but may include medications, physical therapy, surgery, or a combination of these approaches.

Spinal diseases refer to a range of medical conditions that affect the spinal column, which is made up of vertebrae (bones), intervertebral discs, facet joints, nerves, ligaments, and muscles. These diseases can cause pain, discomfort, stiffness, numbness, weakness, or even paralysis, depending on the severity and location of the condition. Here are some examples of spinal diseases:

1. Degenerative disc disease: This is a condition where the intervertebral discs lose their elasticity and height, leading to stiffness, pain, and decreased mobility.
2. Herniated disc: This occurs when the inner material of the intervertebral disc bulges or herniates out through a tear in the outer layer, causing pressure on the spinal nerves and resulting in pain, numbness, tingling, or weakness in the affected area.
3. Spinal stenosis: This is a narrowing of the spinal canal or the neural foramen (the openings where the spinal nerves exit the spinal column), which can cause pressure on the spinal cord or nerves and result in pain, numbness, tingling, or weakness.
4. Scoliosis: This is a curvature of the spine that can occur in children or adults, leading to an abnormal posture, back pain, and decreased lung function.
5. Osteoarthritis: This is a degenerative joint disease that affects the facet joints in the spine, causing pain, stiffness, and decreased mobility.
6. Ankylosing spondylitis: This is a chronic inflammatory disease that affects the spine and sacroiliac joints, leading to pain, stiffness, and fusion of the vertebrae.
7. Spinal tumors: These are abnormal growths that can occur in the spinal column, which can be benign or malignant, causing pain, neurological symptoms, or even paralysis.
8. Infections: Bacterial or viral infections can affect the spine, leading to pain, fever, and other systemic symptoms.
9. Trauma: Fractures, dislocations, or sprains of the spine can occur due to accidents, falls, or sports injuries, causing pain, neurological deficits, or even paralysis.

A zygapophyseal joint, also known as a facet joint, is a type of synovial joint that connects the articulating processes of adjacent vertebrae in the spine. These joints are formed by the superior and inferior articular processes of the vertebral bodies and are covered with hyaline cartilage. They allow for smooth movement between the vertebrae, providing stability and limiting excessive motion while allowing flexibility in the spine. The zygapophyseal joints are supported by a capsule and ligaments that help to maintain their alignment and restrict abnormal movements. These joints can become sources of pain and discomfort when they become inflamed or damaged due to conditions such as arthritis, degenerative disc disease, or injury.

Nerve compression syndromes refer to a group of conditions characterized by the pressure or irritation of a peripheral nerve, causing various symptoms such as pain, numbness, tingling, and weakness in the affected area. This compression can occur due to several reasons, including injury, repetitive motion, bone spurs, tumors, or swelling. Common examples of nerve compression syndromes include carpal tunnel syndrome, cubital tunnel syndrome, radial nerve compression, and ulnar nerve entrapment at the wrist or elbow. Treatment options may include physical therapy, splinting, medications, injections, or surgery, depending on the severity and underlying cause of the condition.

The hypoglossal nerve, also known as the 12th cranial nerve (CN XII), is primarily responsible for controlling tongue movements. Hypoglossal nerve diseases refer to conditions that affect this nerve and result in various tongue-related symptoms. These disorders can be congenital or acquired, and they may stem from different causes such as trauma, tumors, infections, inflammation, or degenerative processes.

Hypoglossal nerve diseases can present with the following symptoms:

1. Weakness or paralysis of the tongue muscles on one or both sides.
2. Deviation of the tongue towards the affected side when protruded.
3. Fasciculations (involuntary muscle twitches) or atrophy (wasting) of the tongue muscles.
4. Difficulty with speaking, swallowing, and chewing due to tongue weakness.
5. Changes in taste and sensation on the back of the tongue and throat.

Some specific hypoglossal nerve diseases include:

1. Hypoglossal nerve palsy: A condition characterized by unilateral or bilateral weakness or paralysis of the tongue due to damage to the hypoglossal nerve. Causes can include trauma, tumors, stroke, multiple sclerosis, or other neurological disorders.
2. Hypoglossal neuritis: Inflammation of the hypoglossal nerve, often caused by viral infections or autoimmune processes, leading to tongue weakness and atrophy.
3. Congenital hypoglossal nerve anomalies: Abnormal development of the hypoglossal nerve during fetal growth can result in various tongue-related symptoms and difficulties with speech and swallowing.
4. Tumors affecting the hypoglossal nerve: Both benign and malignant tumors, such as schwannomas or neurofibromas, can compress or infiltrate the hypoglossal nerve, causing weakness or paralysis.
5. Hypoglossal-facial anastomosis: A surgical procedure that connects the hypoglossal nerve to the facial nerve to restore facial movement in cases of facial nerve palsy. This connection can lead to tongue weakness as a side effect.

A laminectomy is a surgical procedure that involves the removal of the lamina, which is the back part of the vertebra that covers the spinal canal. This procedure is often performed to relieve pressure on the spinal cord or nerves caused by conditions such as herniated discs, spinal stenosis, or tumors. By removing the lamina, the surgeon can access the affected area and alleviate the compression on the spinal cord or nerves, thereby reducing pain, numbness, or weakness in the back, legs, or arms.

Laminectomy may be performed as a standalone procedure or in combination with other surgical techniques such as discectomy, foraminotomy, or spinal fusion. The specific approach and extent of the surgery will depend on the patient's individual condition and symptoms.

The lumbar vertebrae are the five largest and strongest vertebrae in the human spine, located in the lower back region. They are responsible for bearing most of the body's weight and providing stability during movement. The lumbar vertebrae have a characteristic shape, with a large body in the front, which serves as the main weight-bearing structure, and a bony ring in the back, formed by the pedicles, laminae, and processes. This ring encloses and protects the spinal cord and nerves. The lumbar vertebrae are numbered L1 to L5, starting from the uppermost one. They allow for flexion, extension, lateral bending, and rotation movements of the trunk.

Spinal cord compression is a medical condition that refers to the narrowing of the spinal canal, which puts pressure on the spinal cord and the nerves that branch out from it. This can occur due to various reasons such as degenerative changes in the spine, herniated discs, bone spurs, tumors, or fractures. The compression can lead to a range of symptoms including pain, numbness, tingling, weakness, or loss of bladder and bowel control. In severe cases, it can cause paralysis. Treatment options depend on the underlying cause and may include physical therapy, medication, surgery, or radiation therapy.

Cyst fluid refers to the fluid accumulated within a cyst, which is a closed sac-like or capsular structure, typically filled with liquid or semi-solid material. Cysts can develop in various parts of the body for different reasons, and the composition of cyst fluid may vary depending on the type of cyst and its location.

In some cases, cyst fluid might contain proteins, sugars, hormones, or even cells from the surrounding tissue. Infected cysts may have pus-like fluid, while cancerous or precancerous cysts might contain abnormal cells or tumor markers. The analysis of cyst fluid can help medical professionals diagnose and manage various medical conditions, including infections, inflammatory diseases, genetic disorders, and cancers.

It is important to note that the term 'cyst fluid' generally refers to the liquid content within a cyst, but the specific composition and appearance of this fluid may vary significantly depending on the underlying cause and type of cyst.

Surgical decompression is a medical procedure that involves relieving pressure on a nerve or tissue by creating additional space. This is typically accomplished through the removal of a portion of bone or other tissue that is causing the compression. The goal of surgical decompression is to alleviate symptoms such as pain, numbness, tingling, or weakness caused by the compression.

In the context of spinal disorders, surgical decompression is often used to treat conditions such as herniated discs, spinal stenosis, or bone spurs that are compressing nerves in the spine. The specific procedure used may vary depending on the location and severity of the compression, but common techniques include laminectomy, discectomy, and foraminotomy.

It's important to note that surgical decompression is a significant medical intervention that carries risks such as infection, bleeding, and injury to surrounding tissues. As with any surgery, it should be considered as a last resort after other conservative treatments have been tried and found to be ineffective. A thorough evaluation by a qualified medical professional is necessary to determine whether surgical decompression is appropriate in a given case.

A hip contracture is a condition in which the range of motion in the hip joint is limited due to tightness or shortening of the muscles, tendons, or other soft tissues surrounding the joint. This can make it difficult for the person to perform certain movements, such as flexing the hip or bringing the knee up towards the chest. Hip contractures can be caused by a variety of factors, including injury, surgery, prolonged immobility, cerebral palsy, and other neurological conditions. Treatment may include physical therapy, stretching exercises, and in some cases, surgery.

Radiculopathy is a medical term that refers to the condition where there is damage or disturbance in the nerve roots as they exit the spinal column. These nerve roots, also known as radicles, can become damaged due to various reasons such as compression, inflammation, or injury, leading to a range of symptoms.

Radiculopathy may occur in any part of the spine, but it is most commonly found in the cervical (neck) and lumbar (lower back) regions. When the nerve roots in the cervical region are affected, it can result in symptoms such as neck pain, shoulder pain, arm pain, numbness, tingling, or weakness in the arms or fingers. On the other hand, when the nerve roots in the lumbar region are affected, it can cause lower back pain, leg pain, numbness, tingling, or weakness in the legs or feet.

The symptoms of radiculopathy can vary depending on the severity and location of the damage to the nerve roots. In some cases, the condition may resolve on its own with rest and conservative treatment. However, in more severe cases, medical intervention such as physical therapy, medication, or surgery may be necessary to alleviate the symptoms and prevent further damage.

The odontoid process, also known as the dens, is a tooth-like projection from the second cervical vertebra (axis). It fits into a ring formed by the first vertebra (atlas), allowing for movement between these two vertebrae. The odontoid process helps to support the head and facilitates movements such as nodding and shaking. It is an essential structure in maintaining stability and mobility of the upper spine.

The atlanto-axial joint is the joint between the first and second cervical vertebrae, also known as C1 (atlas) and C2 (axis). It consists of two separate joints: the median atlanto-axial joint, which is a pivot joint that allows for rotation of the head, and the paired lateral atlanto-axial joints, which are plane joints that allow for limited gliding movements.

The atlanto-axial joint is surrounded by several ligaments that provide stability and limit excessive movement. The transverse ligament, located on the anterior aspect of the joint, is particularly important as it prevents excessive movement of the atlas on the axis and helps to protect the spinal cord.

Abnormalities or injuries to the atlanto-axial joint can result in instability and potentially serious neurological complications.

The Cauda Equina refers to a bundle of nerves at the lower end of the spinal cord within the vertebral column. It originates from the lumbar (L1-L5) and sacral (S1-S5) regions and looks like a horse's tail, hence the name "Cauda Equina" in Latin. These nerves are responsible for providing motor and sensory innervation to the lower extremities, bladder, bowel, and sexual organs. Any damage or compression to this region can lead to serious neurological deficits, such as bowel and bladder incontinence, sexual dysfunction, and lower limb weakness or paralysis.

An ovarian cyst is a sac or pouch filled with fluid that forms on the ovary. Ovarian cysts are quite common in women during their childbearing years, and they often cause no symptoms. In most cases, ovarian cysts disappear without treatment over a few months. However, larger or persistent cysts may require medical intervention, including surgical removal.

There are various types of ovarian cysts, such as functional cysts (follicular and corpus luteum cysts), which develop during the menstrual cycle due to hormonal changes, and non-functional cysts (dermoid cysts, endometriomas, and cystadenomas), which can form due to different causes.

While many ovarian cysts are benign, some may have malignant potential or indicate an underlying medical condition like polycystic ovary syndrome (PCOS). Regular gynecological check-ups, including pelvic examinations and ultrasounds, can help detect and monitor ovarian cysts.

Spinal nerve roots are the initial parts of spinal nerves that emerge from the spinal cord through the intervertebral foramen, which are small openings between each vertebra in the spine. These nerve roots carry motor, sensory, and autonomic fibers to and from specific regions of the body. There are 31 pairs of spinal nerve roots in total, with 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal pair. Each root has a dorsal (posterior) and ventral (anterior) ramus that branch off to form the peripheral nervous system. Irritation or compression of these nerve roots can result in pain, numbness, weakness, or loss of reflexes in the affected area.

Spondylolisthesis is a medical condition that affects the spine, specifically the vertebrae in the lower back (lumbar region). It occurs when one vertebra slips forward and onto the vertebra below it. This slippage can lead to narrowing of the spinal canal and compression of the nerves exiting the spine, causing pain and discomfort. The condition can be congenital, degenerative, or result from trauma or injury. Symptoms may include lower back pain, stiffness, and radiating pain down the legs. Treatment options range from physical therapy and pain management to surgical intervention in severe cases.

An epidermal cyst is a common benign skin condition characterized by the growth of a sac-like structure filled with keratin, a protein found in the outermost layer of the skin (epidermis). These cysts typically appear as round, firm bumps just under the surface of the skin, often on the face, neck, trunk, or scalp. They can vary in size from a few millimeters to several centimeters in diameter.

Epidermal cysts usually develop as a result of the accumulation of dead skin cells that become trapped within a hair follicle or a pilosebaceous unit (a structure that contains a hair follicle and an oil gland). The keratin produced by the skin cells then collects inside the sac, causing it to expand gradually.

These cysts are generally slow-growing, painless, and rarely cause any symptoms. However, they may become infected or inflamed, leading to redness, tenderness, pain, or pus formation. In such cases, medical attention might be necessary to drain the cyst or administer antibiotics to treat the infection.

Epidermal cysts can be removed surgically if they cause cosmetic concerns or become frequently infected. The procedure typically involves making an incision in the skin and removing the entire sac along with its contents to prevent recurrence.

Medical Definition:

Magnetic Resonance Imaging (MRI) is a non-invasive diagnostic imaging technique that uses a strong magnetic field and radio waves to create detailed cross-sectional or three-dimensional images of the internal structures of the body. The patient lies within a large, cylindrical magnet, and the scanner detects changes in the direction of the magnetic field caused by protons in the body. These changes are then converted into detailed images that help medical professionals to diagnose and monitor various medical conditions, such as tumors, injuries, or diseases affecting the brain, spinal cord, heart, blood vessels, joints, and other internal organs. MRI does not use radiation like computed tomography (CT) scans.
