Back Pain

Most people will experience lower back pain at some point in their lives. Often, the pain will resolve spontaneously within a short period of time. For some people, however, the pain can be persistent and interfere with their ability to function in their daily lives. There are many different causes of lower back pain, and often the symptoms will improve without treatment. However, you should seek immediate medical attention if the following symptoms exist:

  • Lower extremity pain, numbness or tingling
  • Weakness
  • Fever or chills
  • Recent trauma
  • Change in bowel or bladder function
  • Numbness or tingling in your perianal area
  • History of cancer
  • Pain that persists after 2-3 days

The following list includes some of the more common problems that can contribute to lower back pain.

Muscle Strain

There are numerous paraspinal muscles and ligaments that can cause or contribute to back pain. These muscles provide structural support for the spine and assist in movement. A muscle strain occurs when fibers become stretched or torn. A ligament sprain is a similar finding, with similar symptoms. The pain is typically localized in the back and may worsen with movement. Muscle spasm can lead to significant pain and stiffness in the neck and back.

Treatment

Muscle strains and ligament sprains can be managed conservatively, with medications and activity modification. Physical therapy programs will focus initially on exercises that minimally stress the back and then on exercises that condition the trunk muscles.

Lumbar Disc Herniation

The intervertebral disc is made up of a fibrous outer layer called the annulus fibrous and a soft inner layer called the nucleus pulposus. In the lumbar spine, each of the five vertebral bodies is separated by an intervertebral disc. The lumbar disc can be bulging, when it extends beyond the peripheral limits of the disc space. It can also be herniated, when the soft inner portion displaces outside of its normal boundaries. Disc herniations can compress a spinal nerve root, causing pain, numbness or weakness into one of the legs. This type of pain is called radiculopathy. Rarely, bladder or bowel control can be affected. If this occurs, you should seek immediate medical attention.

Diagnosis

The diagnosis of a lumbar disc herniation is made first through patient symptoms and clinical examination. If these suggest that disc herniation has occurred, your provider will likely order an MRI scan. The MRI is used to visualize the disc material and spinal nerves. If you are unable to have an MRI, a myelogram with CT scan is ordered.

Treatment

Conservative treatments include medications and physical therapy. Surgery may also be indicated, when conservative treatments fail or if you develop a neurological deficit.

Clinical Images

Lumbar Spine MRI

This is a sagittal view of a lumbar spine MRI. Notice the discs between the vertebral bodies. They are in good alignment without causing any pressure on the spinal nerves.

This cervical MRI shows stenosis at multiple levels in the spine.  You can see from the sagittal view that the space which is normally occupied by the spinal cord has become smaller.

Lumbar Stenosis

Lumbar stenosis is a narrowing of the spinal canal, which results from a combination of ligament thickening, joint overgrowth, disc bulging and a change in the curvature of the spine. It can cause back pain with radiculopathy. The symptoms typically increase with walking and are alleviated with rest.

Diagnosis

The first step in making a diagnosis of lumbar stenosis is the clinical examination and discussion with your physician your symptoms. Imaging studies are likely ordered, such as an MRI scan and possibly and x-ray. If you are not able to have an MRI, a myelogram and CT scan will be ordered. Sometimes, an EMG and nerve conduction study is also ordered. This test is performed by a trained clinician who delivers electrical stimulation to the muscles and nerves in the legs to evaluate for any nerve damage.

Treatment

Conservative treatments include medications, physical therapy and injections. Surgery may be necessary to decompress the spinal cord and nerves.

Spondylolisthesis

When one vertebral body is moved in relation to another, it is termed spondylolisthesis. Spondylolisthesis can be due to degenerative changes, trauma or congenital abnormalities in the bony architecture of the spinal column. Degenerative spondylolisthesis occurs over time, as a process of intersegmental instability. Fractures in certain parts of the vertebral body can also lead to instability. Congenital malformations in the neural arch, specifically the pars interarticularis, lead to spondylolysis and slippage. Patients with spondylolisthesis present with back pain and/or extremity pain that may change with bending.

Diagnosis

X-rays will confirm the presence of spondylolisthesis. These may be ordered with you bending forwards and backwards to evaluate for movement at the level of the spondylolisthesis. The MRI scan will show the nerves and possible compression. In addition, a CT scan may be ordered to evaluate for possible congenital defect in the bone that can lead to spondylolisthesis.

Treatment

Conservative treatments include medications, bracing, physical therapy and injections. Surgery may be necessary to decompress the spinal cord and nerves with spinal fusion.

Clinical Images

Spondylolysis

A congenital failure of the neural arch to form together is termed spondylolysis. These patients have a defect in the pars interarticularis region of the vertebrae. Spondylolysis leads to slippage, or spondylolisthesis. Often, patients are asymptomatic. However, back pain with or without radiculopathy may develop.

Diagnosis

The best test to visualize spondylolysis is a plain CT scan. X-rays and MRI scans can suggest spondylolysis, but the CT scan is a more definitive test.

Treatment

The treatment of spondylolysis is often conservative, including medications, physical therapy and sometimes a brace. Surgery, when indicated, involves a fusion procedure to stabilize the region.

Clinical Images

This is a CT scan from the lumbar spine, viewed as if you were looking at the spinal canal from the top-down.  Notice how the white bone forms a ring.  This ring encloses the spinal canal.

Scoliosis

Scoliosis refers to an abnormal S-shaped curvature that occurs in the lateral direction. Scoliosis can be congenital, and some individuals require corrective fusions in childhood. However, scoliosis can also be degenerative as a result of degenerative disc disease and ligament laxity. Scoliosis can lead to back pain and extremity pain, if spinal nerves are compressed.

Diagnosis

Scolioisis is best seen on an x-ray. A CT scan can be used to further evaluate the direction of rotation of each of the bones. Often, a CT scan is also used for surgical planning in cases of fusion. MRI scans are used to evaluate for nerve compression.

Treatment

Treatment for scoliosis begins with conservative measures, including physical therapy, medications and sometimes bracing. Pain management consultation for injections is also considered. If a patient has failed the above treatment options, surgical strategies can be discussed. The choice of surgical intervention depends on the patient’s symptoms and also the degree of scoliosis and stenosis. There are some cases in which the nerves can be decompressed with a minimally-invasive approach. There are some cases, however, where a fusion procedure is required to stabilize the spine after the nerves have been decompressed.

Degenerative Disc Disease

Disc degeneration occurs as the disc loses collagen and begins to collapse. Loss of the disc material contributes to decrease in motion at this level and pain. In addition, as the disc space narrows, the endplates of the adjacent vertebral bodies develop sclerosis and osteophytes. These changes can also produce back pain. Disc degeneration can also lead to disc herniation. Back pain is difficult to treat surgically, and conservative treatment is the first line approach.

Diagnosis

Disc degeneration can be appreciated on MRI scans as “black discs”. The MRI will also show any possible nerve compression. X-rays are also useful tests in this condition, and they will show collapsed disc spaces.

Treatment

Medications, physical therapy and injections can be used to achieve relief of chronic back pain associated with degenerative disc disease.

Cauda Equina Syndrome

The cauda equina is a group of nerve endings in the lower end of the spinal column. During development, the bony structures of the spinal column lengthen at a faster rate than the spinal cord. In most adult persons, the spinal cord ends at the level of the L1-L2 vertebrae. From this point, the cauda equina occupies the remainder of the spinal column. With compression of the cauda equina, patients have disturbance of the urinary and anal sphincters, saddle anesthesia, lower extremity weakness and sexual dysfunction. Patients also may have absent reflexes in the legs. Compression of the cauda equina can result from a large disc herniation, tumor, trauma or epidural hematoma.

This patient presented with lower extremity pain and urinary incontinence.  The large disc herniation was found in the lumbar spine, causing cauda equine syndrome.  Following urgent surgery, the patient had resolution in the leg pain and a significant improvement in urinary function.

Diagnosis

Clinical presentation is crucial in the diagnosis of cauda equina syndrome. In order to avoid a delay in treatment, the physician will have a high suspicion of the diagnosis based on your signs and symptoms. MRI scan is often ordered STAT to avoid a treatment delay.

Treatment

Surgical decompression is necessary and ideally should be performed early to avoid long term deficit.

Spinal Fracture

There are many different types of spinal fractures.

Compression fractures appear as a loss of height in the vertebral body. These fractures are commonly related to osteoporosis, but malignancy can also predispose an individual to develop compression fractures by weakening the bony matrix of the spinal column. These kinds of fractures more commonly occur in the thoracic and lumbar regions of the spine. Patients typically have pain in the middle to lower back and can be tender to the touch. They may or may not have radiculopathy. Often these patients can be treated conservatively, with bracing, medications and physical therapy. There is also a surgical procedure, called kyphoplasty, which can be performed if conservative treatment is ineffective. When there is a significant amount of compression, patients may require more extensive surgery to stabilize the fracture.

Fractures in the cervical spine can fall into many different classifications. Often, these are traumatic fractures. Patients require a thorough neurological assessment to evaluate for any deficits or possible spinal cord injury. Treatment will depend on the type of fracture. Most patients require immobilization and/or surgical stabilization.

This lateral xray shows a compression fracture in the lumbar spine.  You will notice how the fractured vertebrae appears to have less height than the other vertebral bodies.

Spinal Cord Tumor

Spinal cord tumors may be classified into one of the following groups:

  1. Extradural—Arise outside the spinal cord and dural sac
  2. Intradural extramedually—Arise inside the dural sac, but outside the spinal cord; often these are tumors that involve spinal membranes
  3. Intramedullary—Arise in the substance of the spinal cord

Most primary spinal tumors are benign and present when they become large enough to compress a nerve or the spinal cord, producing radiculopathy or myelopathy. Malignant primary spinal tumors are less common, but can occur. Metastatic spinal tumors can also arise from malignancy elsewhere in the body.

Diagnosis

Diagnosis of spinal cord tumor is often made with MRI scans. CT scans are useful, especially in diagnosis of extradural tumors that invade bone tissue. Based on the type of tumor, additional studies may be ordered to evaluate additional areas for involvement.

Treatment

Treatment of spinal cord tumor is dependent on the type of tumor and clinical presentation. In many cases, surgical resection is the best approach. With any type of tumor surgery, the goal of surgical resection is to remove as much of the tumor as is safely possible and spare functional neural tissue. Radical resection can often be achieved in benign tumor types. A limited resection or biopsy combined with multidisciplinary medical treatments may be recommended for malignant tumors. We work closely with both medical oncologists and radiation therapists to maximize the possibility of complete recovery.

Tethered Cord

In most people, the spinal cord and nerves float freely inside the dural sac surrounded by cerebrospinal fluid. In tethered cord syndrome, the spinal cord remains attached to the inside of the spinal membranes which limits its movement. It begins during development, as the spinal canal grows at a rate faster than the cord. If the spinal cord remains attached, the nerve tissues become stretched and this interferes with their function. Patients with tethered cord typically present in childhood, and tethered cord can have associated cutaneous findings. However, although less common, tethered cord patients can first present in adulthood. Patients may have difficulty walking, weakness in their legs, bladder dysfunction or lower back pain.

Diagnosis

The diagnosis of tethered cord syndrome depends on MRI scan. Clinical presentation increases suspicion for this diagnosis.

Treatment

Treatment for symptomatic tethered cord syndrome is surgical separation of this attached region.
