Tumors of the spinal vertebrae may result in pain due to vertebral fractures or to the displacement or compression of the neural elements by tumor expansion. The most common primary benign bone tumor of the spine is a hemangioma which rarely causes symptoms. Other less common primary benign tumors, particularly seen in younger patients, include osteoid osteomas and osteoblastomas. Osteoid osteomas may cause a painful scoliosis. The most common primary malignant tumor of the spine is the chordoma. Chordomas are rare and are typically midline tumors that occur most commonly in the sacrum and clivus. The most common non-primary malignancies in the spine are metastatic disease and multiple myeloma. Conventional radiographs are an insensitive means of detecting metastatic disease, particularly for lytic (destructive) lesions.

Pet (positron emission tomography) may also any help distinguish between a benign and malignant fracture. Trauma, fractures of the spine are more common in the cervical and thoracic spine than in the lumbar spine. Seatbelt injuries or Chance fractures typically occur in the upper lumbar spine. Conventional radiographs are used as a screening exam. With severe trauma, particularly when a patient is unconscious, a ct exam of the entire spine is typically performed to determine if a spine fracture is present. Mri is utilized to evaluate the integrity of the disc and spinal ligaments and the condition of the spinal cord and neural elements. Mri may detect unsuspected vertebral fractures by detecting hope edema in the fractured vertebral body. Mri is also the optimal exam to assess the ligaments and soft tissue which may affect spinal stability. Tumor, the elderly age group that is prone to osteoporotic compression fractures is also more likely to present with back pain due to the development of spinal tumors and vertebral body metastases (tumor that has originated from another site in the body and has spread. Metastases may replace healthy bone, weakening the vertebral bodies, and increasing the risk of fracture. Mri may help to distinguish a benign from a malignant fracture by detecting the replacement of normal marrow by abnormal tumor or by detecting a soft tissue mass that is associated with a bone tumor.
Mri is particularly useful in the assessment of the soft tissues which may be injured at first the time of a fracture. Mri is the optimum means to detect a disc herniation that may have occurred at the time of a fracture. Mri also provides useful information as to whether a fracture is acute or chronic. This is determined by the presence of edema in the fractured vertebra. The age of a fracture may determine whether a vertebroplasty or a kyphoplasty is performed to alleviate a patient's symptoms. Vertebroplasty and kyphoplasty are recent techniques for the treatment of compression fractures whereby a type of cement is percutaneously injected into the vertebral bodies to relieve symptoms, restore vertebral body strength and possibly increase vertebral body height. These procedures are most successful when the compression fracture is in the acute or subacute stage. Mri may also be of benefit to determine if a fracture is due to osteoporosis (called a benign fracture) or to a tumor (called a malignant fracture).
Conventional radiographs should be the initial imaging exam for the evaluation of spinal fractures. Radiographs provide accurate information as to the number of vertebral bodies involved and the degree of the vertebral body compression. Radiographs also provide means to assess spinal alignment after a fracture has occurred. Asymptomatic compression fractures that are detected incidentally when imaging the spine for other medical conditions may be followed for progression in order to determine if a spinal deformity develops. Due to decreased bone density, the evaluation of osteoporotic bones may be difficult with standard radiographs; other imaging modalities may be useful to determine if a fracture is present. Ct is the optimal exam to determine the extent of a fracture and the position of all the fracture fragments. Ct is also an excellent means to confirm that the facture is due to osteoporotic weakened bone and not to weakened bone from tumor infiltration. With its multiplanar capabilities (the ability to reconstruct images of the spine in alternative planes from the initially acquired axial images ct is the optimal test to evaluate spinal alignment after a fracture and to detect write subtle non-displaced fractures.
Fractured or collapsed vertebrae may be very painful and may lead to spinal stenosis and compression of the neural elements. Fractured vertebrae may also result in spinal malalignment which may exacerbate a patient's pain. Most vertebral compression fractures involve the vertebral body and may result in an anterior wedge deformity. Occasionally, a fracture may involve the posterior cortex of the vertebral body. If the posterior cortex of the vertebral body is displaced into the central spinal canal, the bony deformity may result in spinal stenosis and compression of the neural elements. In the thoracic spine, a fractured vertebral body may result in spinal cord compression. The thoracic spine is the most common location for osteoporotic fractures, but lumbar fractures are not infrequent.

Listhesis refers to the alignment of two adjacent vertebral bodies in the spine. Anterior displacement of the cephalad vertebral body with respect to the caudad vertebral body is called anterolisthesis and posterior displacement of the cephalad vertebral body with respect to the caudad vertebral body is called retrolisthesis. A lateral displacement of the cephalad vertebral body with respect to the caudad vertebral body is called a right or left lateral listhesis. Abnormal spinal alignment may lead to asymmetric loads on the spine and spine degeneration. Erect radiographs of the spine are optimal to evaluate spinal alignment (also referred to as spinal balance).
Ct and mri can provide additional information as to the etiology and effects of the listhesis. An anterolisthesis is typically the result of facet arthritis or spondylolysis (stress fractures of the pars interarticularis). With ct and mri, it is possible to assess the dimensions of the central canal and neural foramina and the effects of bony proliferation on the thecal sac and the nerve divergent roots. If surgery is needed to stabilize the spine and to prevent progression of the spinal deformity, both ct and mri examinations are utilized to plan appropriate treatment. In certain instances, ct myelography, which is a ct scan performed after iodinated contrast is administered into the spinal canal via a spinal needle, may be indicated to better visualize the spinal cord and spinal nerve roots within the thecal sac. Osteoporosis, osteoporosis is a structural weakening of bone, most commonly affecting postmenopausal females, and has important implications in the spine. Osteoporotic bone is more susceptible to a fracture, which may occur with even minor trauma.
These measurements are also critical in assessing the impact of therapeutic interventions to correct the scoliosis and aid in the assessment of the progression or resolution of the spinal curvature. These measurements can be performed in all age groups, including children with congenital anomalies. With the development of new imaging techniques the radiation dosage to the patient has been significantly reduced for the evaluation of scoliosis. Decreasing radiation dosage is extremely important due to the young age of many patients with scoliosis and the need for serial exams. Many surgeons request stress or lateral bending views of the spine to provide additional prognostic information for preoperative planning.
In post-surgical patients, conventional radiographs also serve as a means to reevaluate the spinal curvature and the integrity of spinal instrumentation. Ct (computed tomography) and, mRI (magnetic resonance imaging) can provide additional information in patients with scoliosis. Mri may be indicated to assess the brain and spinal cord in patients with certain types of scoliosis or congenital anomalies. Ct may be indicated to assess vertebral body shape, particularly in preoperative planning where the size of the vertebral pedicles must be determined. In rare cases, scoliosis may be the result of a syndrome such as neurofibromatosis or a tumor such as an osteoid osteoma. In these cases, cross sectional imaging (ct and mri) is invaluable for the initial diagnosis and treatment of these conditions. Scoliosis produces abnormal forces on the spine that may lead to early degenerative changes of the spine. In addition, patients that have undergone a spinal fusion to correct their scoliosis may be prone to spinal degeneration at the level adjacent to where the spinal fusion ends. Ct and mri can assess these degenerative changes.
Degenerative scoliosis: An overview
Scoliosis may also database occur with congenital malformations of the spine or may be due to spinal degeneration. Scoliosis can occur in the mediolateral or in the anteroposterior direction. In the mediolateral direction, the curvature is summary rightward or leftward and is named according to the direction of the convexity of the curve. In the anteroposterior direction, the curvature is referred to as kyphosis (increased posterior convexity of the spine) or lordosis (increased posterior concavity of the spine). Most scoliosis also has a rotational component. Conventional radiographs ( x-rays ) are an excellent means for assessing scoliosis. Examinations at hss are performed utilizing one long continuous image of the entire spine, usually obtained with the patient standing. Utilizing this technique, the angles of the spinal curvature can be measured and the grade of the deformity can be determined. These measurements can be used to predict the progression of scoliosis and to determine if the spinal alignment changes over time.
