Spondyloptosis and multiple-level spondylolysis. (1/167)
An unusual case of a combination of multiple bilateral spondylolyses (L2, 3 and 4), spondylolisthesis at L3/4, spondyloptosis at L4/5 and sacralization of L5 in a teenage female is described. The patient had severely increasing lower back pain radiating to the left lower limb. Radiography identified the abnormalities and myelography revealed complete obstruction and compression of the thecal sac at the L4/5 level. The case was treated surgically by posterior decompression, corpectomy and fusion in a three-stage operation. The follow-up was extended to 2 years with no complications. No similar case has previously been reported. (+info)Cervical osteoarthropathy: an unusual cause of dysphagia. (2/167)
PRESENTATION: A 72-year-old man complained of progressive dysphagia for solids associated with a sensation of foreign body in his throat for 2 years. A barium swallow showed a bridging osteophyte between C4 and C5 vertebrae indenting the oesophagus posteriorly and displacing it anteriorly. OUTCOME: He refused surgical intervention and was given dietary advice. After 6 months, his weight was steady and he was able to swallow semi-solid food without difficulty. (+info)Pitfalls and delay in the diagnosis of Pancoast tumour presenting in orthopaedic units. (3/167)
Pancoast tumours present a difficult and peculiar problem. Their clinical manifestations may be extrapulmonary. The underlying lesion may be missed in patients presenting with predominantly orthopaedic symptoms. We present four consecutive cases, which were referred to our clinic and the diagnosis was made with mean delay of 18.5 months from the beginning of symptoms. (+info)Association of transforming growth factor beta1 genotype with spinal osteophytosis in Japanese women. (4/167)
OBJECTIVE: To examine the possible relationship between a T-->C polymorphism at nucleotide position 29 of the transforming growth factor beta1 (TGFbeta1) gene and genetic susceptibility to radiographic spinal osteophytosis. METHODS: A total of 540 postmenopausal Japanese women were subjected to radiography of the spine and determination of bone mineral density (BMD) for the lumbar spine and total body. Changes in lumbar intervertebral discs were examined in 67 individuals with either osteoporosis or spinal osteophytosis by magnetic resonance imaging (MRI). TGFbeta1 genotype was determined with an allele-specific polymerase chain reaction assay. The serum concentration of TGFbeta1 was measured in 29 control subjects and in 36 patients with spinal osteophytosis. RESULTS: Among all study subjects, the prevalence of radiographic spinal osteophytosis in individuals with the CC genotype was greater than that in those with the TC or TT genotype. Logistic regression analysis, adjusted for age, height, body weight, time since menopause, smoking status, body fat, lean mass, and either lumbar spine or total body BMD, demonstrated that the frequency of the C allele in subjects with spinal osteophytosis was significantly greater than that in those without this condition. Comparison among control, osteoporosis, and spinal osteophytosis groups also revealed that the C allele was more prevalent in subjects with osteophytosis than in controls, even after adjustment for BMD. In contrast, as previously shown, the frequency of the C allele was lower in osteoporosis patients than in controls. The intervertebral disc area and the ratio of disc area to vertebral body area, as determined by MRI, were also lowest in subjects with the CC genotype. The serum concentration of TGFbeta1 increased with the number of C alleles in both controls and patients with spinal osteophytosis. CONCLUSION: The T29-->C polymorphism of the TGFbeta1 gene exhibited inverse patterns of association with genetic susceptibility to spinal osteophytosis and with osteoporosis. Although radiographic evaluation of osteophytes might not reflect the actual disease severity, the C allele, which protects against osteoporosis, may be a risk factor for genetic susceptibility to spinal osteophytosis. (+info)Tricortical cervical inter-body screw fixation. (5/167)
A new tricortical method of screw implantation for anterior cervical interbody plate fixation is described. The screws are placed obliquely such that they engage the anterior cortex of the body and traverse through the cortices adjoining the disc space. By this method the screws not only hold the plate firmly with a tricortical purchase, but by virtue of their course stabilize the two adjoining vertebral bodies by themselves. Sixteen patients were treated by this method. In three of these cases only tricortical screws without the metal plate were used for fixation. The advantages of the technique are discussed. (+info)Changes in the loads on an internal spinal fixator after iliac-crest autograft. (6/167)
Spines are often stabilised posteriorly by internal fixation and anteriorly by a bone graft. The effect of an autologous bone graft from the iliac crest on implant loads is unknown. We used an internal spinal fixation device with telemetry to measure implant loads for several body positions and activities in nine patients before and after anterior interbody fusion. With the body upright, implant loads were often higher after than before fusion using a bone graft. Distraction of the bridged region led to high implant loads in patients with a fractured vertebra and to marked changes in load in those with degenerative instability. Leaving the lower of the bridged intervertebral discs intact led to only small changes in fixator load after anterior interbody fusion. A bone graft alone does not guarantee a reduction of implant loads. (+info)A case report of synovitis, acne, pustulosis, hyperostosis and osteitis syndrome presenting with spondylodiscitis. (7/167)
SAPHO syndrome stands for synovitis, acne, pustulosis, hyperostosis and osteitis. The common site of skeletal lesions in this syndrome is the sternocostoclavicular area. Spondylodiscitis is rarely described in published studies. In general, skin lesions develop before the onset of skeletal lesions. We report a case of SAPHO syndrome in which spondylodiscitis developed more than 1 year before the onset of pustulosis. (+info)Cervical spondylotic myelopathy: a common cause of spinal cord dysfunction in older persons. (8/167)
Cervical spondylotic myelopathy is the most common cause of spinal cord dysfunction in older persons. The aging process results in degenerative changes in the cervical spine that, in advanced stages, can cause compression of the spinal cord. Symptoms often develop insidiously and are characterized by neck stiffness, arm pain, numbness in the hands, and weakness of the hands and legs. The differential diagnosis includes any condition that can result in myelopathy, such as multiple sclerosis, amyotrophic lateral sclerosis and masses (such as metastatic tumors) that press on the spinal cord. The diagnosis is confirmed by magnetic resonance imaging that shows narrowing of the spinal canal caused by osteophytes, herniated discs and ligamentum flavum hypertrophy. Choice of treatment remains controversial, surgical procedures designed to decompress the spinal cord and, in some cases, stabilize the spine are successful in many patients. (+info)Spinal osteophytosis, also known as spinal osteophyte formation or bone spurs on the spine, refers to the abnormal growth of bony projections along the vertebral column's margins. These bony outgrowths develop due to degenerative changes, inflammation, or injury in the joints between the vertebrae (facet joints) and can cause stiffness, pain, and reduced mobility. In some cases, spinal osteophytosis may lead to complications such as spinal stenosis or nerve compression.
An osteophyte, also known as a bone spur, is a bony projection that forms along the margins of joints, often as a result of degenerative changes in the cartilage and underlying bone. These changes are most commonly seen in conditions such as osteoarthritis, where the protective cartilage that cushions the ends of bones breaks down, leading to inflammation, pain, and reduced mobility.
Osteophytes can develop in any joint in the body, but they are most commonly found in the spine, hips, knees, and hands. They may vary in size from small bumps to large, irregular growths that can restrict joint movement and cause discomfort or pain. In some cases, osteophytes may also compress nearby nerves, leading to symptoms such as numbness, tingling, or weakness in the affected limb.
While osteophytes are often considered a sign of aging or joint degeneration, they can also be caused by other conditions that put excessive stress on the joints, such as injury, infection, or inflammatory arthritis. Treatment for osteophytes typically involves addressing the underlying cause of joint damage, along with pain management strategies such as physical therapy, medication, or in some cases, surgery.
Osteoarthritis (OA) of the knee is a degenerative joint disease that affects the articular cartilage and subchondral bone in the knee joint. It is characterized by the breakdown and eventual loss of the smooth, cushioning cartilage that covers the ends of bones and allows for easy movement within joints. As the cartilage wears away, the bones rub against each other, causing pain, stiffness, and limited mobility. Osteoarthritis of the knee can also lead to the formation of bone spurs (osteophytes) and cysts in the joint. This condition is most commonly found in older adults, but it can also occur in younger people as a result of injury or overuse. Risk factors include obesity, family history, previous joint injuries, and repetitive stress on the knee joint. Treatment options typically include pain management, physical therapy, and in some cases, surgery.
The spinal cord is a major part of the nervous system, extending from the brainstem and continuing down to the lower back. It is a slender, tubular bundle of nerve fibers (axons) and support cells (glial cells) that carries signals between the brain and the rest of the body. The spinal cord primarily serves as a conduit for motor information, which travels from the brain to the muscles, and sensory information, which travels from the body to the brain. It also contains neurons that can independently process and respond to information within the spinal cord without direct input from the brain.
The spinal cord is protected by the bony vertebral column (spine) and is divided into 31 segments: 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal. Each segment corresponds to a specific region of the body and gives rise to pairs of spinal nerves that exit through the intervertebral foramina at each level.
The spinal cord is responsible for several vital functions, including:
1. Reflexes: Simple reflex actions, such as the withdrawal reflex when touching a hot surface, are mediated by the spinal cord without involving the brain.
2. Muscle control: The spinal cord carries motor signals from the brain to the muscles, enabling voluntary movement and muscle tone regulation.
3. Sensory perception: The spinal cord transmits sensory information, such as touch, temperature, pain, and vibration, from the body to the brain for processing and awareness.
4. Autonomic functions: The sympathetic and parasympathetic divisions of the autonomic nervous system originate in the thoracolumbar and sacral regions of the spinal cord, respectively, controlling involuntary physiological responses like heart rate, blood pressure, digestion, and respiration.
Damage to the spinal cord can result in various degrees of paralysis or loss of sensation below the level of injury, depending on the severity and location of the damage.
Osteoarthritis (OA) is a type of joint disease that is characterized by the breakdown and eventual loss of cartilage - the tissue that cushions the ends of bones where they meet in the joints. This breakdown can cause the bones to rub against each other, causing pain, stiffness, and loss of mobility. OA can occur in any joint, but it most commonly affects the hands, knees, hips, and spine. It is often associated with aging and can be caused or worsened by obesity, injury, or overuse.
The medical definition of osteoarthritis is: "a degenerative, non-inflammatory joint disease characterized by the loss of articular cartilage, bone remodeling, and the formation of osteophytes (bone spurs). It is often associated with pain, stiffness, and decreased range of motion in the affected joint."
