This is the reason why anterolisthesis refers to the condition of the spine in which the upper body of vertebral, the area shaped like drum at the front of each vertebrae slips forwards on to the vertebra. This is basically another term for spondylolisthesis. The vertebrae are the bones that protect the spinal cord. Each vertebra has a thick drum-shaped area in front called a vertebral body. Between the vertebrae are spaces that allow nerves (nerve roots) to go from the spinal cord to other parts of the body. In anterolisthesis, there is abnormal positioning of the upper vertebral body when compared to the body of the lower vertebra.

Cunningham and his colleagues at hss are looking at ways to optimize bone tissue. Substances called bone morphogenic proteins (BMPs) may actually help build bone and already have a role in augmenting spinal fusions. In addition, ensuring that patients are not Vitamin d and/or calcium deficient can help to strengthen the bone and improve the patients ability to tolerate the insertion of rods, screws, and other instrumentation, as needed. Finally, some research in the field is focusing on surgical techniques that are less invasive or minimally invasive, a development that would, in some cases, allow surgeons to perform procedures using an incision of one to two inches in length instead of requiring the longer. This is expected to not only minimize soft tissue trauma, but to be better tolerated striped by patients, and allow them to become mobile again more quickly following surgery. "This makes good sense for patients who require short fusions, or longer fusions that are straightforward. "However, for those who require more extensive surgeries involving decompressions and fusions, traditional open approaches may be unavoidable."

Summary prepared by nancy novick; images by the hss department of Radiology and Imaging. Read about Anteriolisthesis Symptoms, causes and Treatment. The term anterolisthesis is derived from a latin word ante that means front and a greek word listhesis that means sliding down on a path that is slippery. Putting the terms together, you will have antelisthesis that means a front slide down a path that is slippery.
Patients who undergo decompression for stenosis or radicular symptoms almost always have an improvement in symptoms. Those whose pain, numbness, or weakness was intermittent prior to surgery tend to experience the greatest benefit. Patients with degenerative scoliosis who undergo fusion of the spine for isolated back pain have results that are comparable to those achieved in patients with degeneration and straight spines. Good outcomes are also based on appropriate assessment of surgical candidates by a multidisciplinary team,. Cunningham notes, especially in an older population. "Whenever we consider surgery, we have to ask, 'does the patient have other medical problems that will make it difficult to tolerate surgery or to participate in rehabilitation? Is she or he vegetarianism taking any medication that will interfere with surgery and recovery, and is it necessary to stop these medications temporarily? future directions in Treatment In order to continue improving outcomes in treatment,.

Note the absence of bone in the center of the canal in the image on the left, as shown by the white arrow, due to the decompression. . Also note the excellent fusion bone produced in the cages between the vertebral bodies in the image on the right, as shown by the green arrows. The instrumentation (rods and screws) can be seen in the center of each image. "Our goal in surgery is to alleviate the pain, restore and maintain stability, and to correct the curve as much as is safely possible. To help protect the patient during surgery, the nerves are monitored through wires attached to the skin in the arms and legs, which are then connected to a computer for interpretation, and are overseen by an filsafat hss neurologist. Treatment Results For the majority of patients with degenerative scoliosis, pain relief or reduction can be achieved with aggressive use of non-surgical measures. In patients for whom surgery becomes necessary, the results vary with the underlying problem.

Figure 12 (right mri of the same patient after spine decompression surgery, with an increased nerve space and 90 improvement in stenosis and radicular symptoms. "In determining the appropriate surgery we have to look at the entire spine. "For example, although the patient with degenerative scoliosis may only have radicular symptoms, if we perform a decompression only and do not stabilize the scoliosis, the resulting instability generated by the removal of bone and ligaments can be problematic. Therefore, fusion may be necessary, in addition to the decompression, to maintain the stability of the spine. If we find spondylolisthesis at one or more levels of the spine, we can expect this deformity to progress, and we typically need to address this with a combined decompression and fusion as well."

In patients who are experiencing leg symptoms only, an epidural steroid injection can be considered. The concept of an epidural injection is that the needle is guided either from the midline skin or from the side, and the tip of the needle is advanced to an area near one of the spinal nerves that is either inflamed or is being. A slightly different epidural technique is called a caudal, where the needle is inserted at the base of the spine. With any of the techniques used, the purpose is to deliver corticosteroids to bathe the affected nerve roots, thereby reducing inflammation and pain (see figure 6, above). Injection therapy may continue to be effective for some time; however, patients in whom it is ineffective, or in whom it becomes ineffective, may eventually be candidates for surgery.
Surgical Treatment Surgical treatment for degenerative scoliosis may involve a fusion, a decompression, or both. If the patients pain is restricted to the back and degenerative changes in the facet joints, fusion in the affected area may be recommended. In essence, the vertebrae are "welded" together and screws or other instrumentation are used to secure and immobilize the bone, with the goal of eliminating the pain associated with movement in that area. Figure 9 (left x-ray of a patient with degenerative scoliosis (50 degrees) and lateral spondylolisthesis prior to fusion surgery. Figure 10 (right x-ray of the same patient after fusion surgery with instrumentation, which eliminated her listhesis and reduced her curve to 10 degrees. In the presence of stenosis and radicular symptoms, decompression surgery (also known as laminectomy) is performed to take pressure off the nerves, a procedure that involves the removal of bony structures, ligaments, and in some cases, other soft tissues that help to support the spine.
Cunningham notes that Oxycodone is a common and typical narcotic to use on rare occasions to manage extreme pain symptoms. "Narcotics can offer effective pain relief on a short term basis; for example, in the week or so leading up to surgery or for a few weeks following surgery he says. "However, these drugs are not a good choice long-term as the patient accommodates to the dose and requires increasingly greater doses of the drug to achieve pain relief. Moreover, they eventually become ineffective." Injections If oral drugs do not offer sufficient relief for axial and/or radicular symptoms in the back and legs, the patient may be referred to a physician specially trained in physiatry or pain management for injection-based treatment. For back pain due to symptoms coming from the facet joints, the specialist may decide to perform a facet injection. Facet injections deliver two medications directly into the joint: a numbing agent and a corticosteroid which is intended to reduce inflammation.
"Injections can be helpful in two ways explains. "If the patient feels numb or funny in the injected area, but the pain is still there, we know we have not found the problematic facet joint. However, if the pain does goes away, we know weve found the correct facet joint responsible for causing the pain symptoms. At this point, the cortisone reduces inflammation and diminishes - or in some cases completely relieves - pain for a matter of weeks to months." Because more than one facet joint may be affected in degenerative scoliosis, the patient may require multiple injections. If pain returns after the facet injections, the specialist may consider a facet rhizotomy, in which a special thermal probe is inserted near a small nerve just outside of the painful facet joint. The probe can then be heated up where it contacts the nerve and serves to destroy the nerve. This process of rhizotomy effectively "turns off" pain signals to the brain. This procedure can provide several months to years of relief.

Figure 8 (right x-ray showing anterior spondylolisthesis, also known as anterolisthesis. Note the white outlined arrow pointing to the affected vertebra. Non-Surgical Treatment Many patients with degenerative scoliosis achieve pain relief from one of umum a number of non-surgical treatments, including: observation kites avoidance of activities that exacerbate symptoms exercises to strengthen muscles (physical therapy, pilates, or yoga) moist heat or cold acupuncture manipulations oral medication regimens injection. For back pain, the orthopaedic surgeon may recommend either a non-steroidal anti-inflammatory drug (nsaid) such as ibuprofen or naproxen, or a drug from the cox-2 inhibitor class of medications, such as celecoxib. For radicular symptoms, drugs that reduce inflammation in the nerves and surrounding soft tissues may be prescribed, or drugs that reduce "overactivity" in nerves (neuroleptics) can be used to limit symptoms. Although the neuroleptic agents (such as gabapentin or pregabalin) can be very effective, they also depress the function of normal nerves and can leave patients with a "rubbery" sensation in the legs; in addition, some patients taking these drugs report feeling sleepy much of the. Anti-depressants may also improve radicular symptoms, although the mechanism involved is not well understood.

Magnetic resonance imaging (MRI) may also be used to obtain information about the nerves, disks, and soft tissue in the spine. This is particularly helpful in determining the cause of radicular symptoms in the legs. Figure 5 (left mri of a festivals patient with a facet cyst (shown by he green arrow) causing compression of nerves. Figure 6 (right mri of same patient after facet injection and cyst rupture (shown by the green arrow completely relieving the compression and eliminating the patient's pain. When assessing a patient in whom degenerative scoliosis is suspected, the orthopedic spine surgeon looks at the angles in the spine as well as the balance of alignment between the head, spine, and hips. If a curve is present, its important to assess whether it is likely to progress and to find other factors that may be contributing to the patients deformity, such as spondylolisthesis, a condition in which one vertebra slides forward, backward, or sideways relative to the. Spondylolisthesis suggests instability of the spine and can produce stenosis (abnormal narrowing of the spinal canal pain, and sometimes nerve injury.

may be a condition called foot drop, in which the patient has difficulty lifting the front part of the foot. Patients with degenerative scoliosis who have developed stenosis may also experience fatigue when walking or a heaviness in the legs that subsides when the he or she leans forward or sits down. Diagnosis and Imaging, in addition to a physical exam and patient history, orthopedic surgeons use imaging techniques to confirm the diagnosis of degenerative scoliosis. These will include: full spine x-rays from the front and from the side and in some cases. Ct scan, which can provide additional detail including evidence of arthrosis of the facet joints. Ct images may also reveal the presence of small fractures that may not be visible on x-ray images.

Degenerative changes can occur in the discs or the facets. When arthritis develops in the facet joints, it is very similar to the process that occurs in the other joints of the body, with thinning of the joint cartilage and rubbing together of the bone ends. Disc degeneration includes the inner part of the disk: a jelly-like substance called the nucleus pulposis that begins to dry out as it ages, or the outer part of the disk: the thickly ligamentous annulus fibrosis, which develops rips and cracks as it wears. The cumulative degenerative changes in all three of these can result in spinal stenosis, in which the passage surrounding the spinal cord and cauda equina become constricted and the nerves red circumferentially compressed. Symptoms, patients with degenerative scoliosis usually seek medical attention when they experience pain or other symptoms in the back, hip, buttocks, or legs, according. Cunningham, md, phd, who is an Orthopaedic Surgeon at Hospital for Special Surgery (HSS). Pain in the back is typically related to spine arthrosis or muscle spasms, and can radiate into the buttocks, the thighs, and the hips. These are referred to as axial symptoms. Radicular symptoms result from compression or pinching of a nerve, and may include shooting pains, sometimes described by patients as "lightning bolts sciatica, or numbness in the legs.

Introduction, degenerative changes of the vertebrae and disks that make up the spine are common in the aging population and may be associated with either osteoarthritis or osteoporosis. However, when these changes result in an asymmetry, a sideways curve of the spine measuring 10 degrees or greater, the condition is described as degenerative scoliosis. The cause of spinal osteoarthritis and degenerative scoliosis vertebrae is not known, but clearly the condition is accentuated by daily "wear and tear" or micro-trauma, and activities that jar the spine repeatedly - for example, as in a person who operates a jackhammer. Less frequently, a fall or other traumatic accident can ultimately lead to a diagnosis of degenerative scoliosis. To understand how this process occurs, it is helpful to think of the spine as a series of bony blocks, the vertebrae, which are connected by facet joints that permit movement in the spine. Disks sit between the vertebrae and provide cushioning and protection. The spinal cord runs through the spinal canal, a passage created by the vertebrae.
