For Providers Radiology Resident Case of the Week, May 15, 1997 Lumbar disk herniation and conjoined nerve root sleeve (lumbar) Eric Fitzcharles, M.D. Peer Review Status: Not Internally Reviewed Clinical Sx: 53-year-old male with several-month history of increasing right lower extremity weakness and numbness. Etiology/Pathophysiology: Disk degeneration is noticeable by the age of 20. The process consists of desiccation, or water loss in the nucleus pulposus and decreased tissue resiliency with decrease in the height of the disk space. With age, the initially soft and gelatinous nucleus pulposus is replaced by fibrocartilage and the distinction between nucleus pulposus and annulus fibrosis becomes less distance. The annulus becomes fissured and negative pressures bring nitrogen out of solution causing vacuum phenomenon. Disk height loss leads to malalignment and all of these processes permit disk material to bulge and subsequently herniate. The second finding in this patient was a conjoined nerve root sleeve. This is a congenital anomaly that is considered a normal variant and is found in 1-3% of the population. Pathology: The terminology of disk disease is at times muddy, however the following definitions are helpful: bulge: concentric smooth circumferential expansion of softened disk material beyond the confines of endplates. Protrusion = herniation: focal protrusion of disk material maintaining broad base with parent disk due to weakened or ruptured annulus fibrosus but intact posterior longitudinal ligament (herniation implies ruptured annulus fibrosus but protrusion doesn't necessarily). Extrusion: prominent focal extrusion of disk material with only an isthmus of connection with the parent disk due to ruptured annulus and intact or ruptured posterior longitudinal ligament. Free fragment: frank separation of disk material from parent disk (may migrate). There was no resected pathologic specimen from this patient.

Peer Review Status: Externally Peer Reviewed Superior Portion of Duodenum The highest part of the duodenum varies from about the lower third of the tenth thoracic vertebra to the first lumbar disk. The average position is at a level between the twelfth thoracic disk and the upper third of the first lumbar vertebra, according to Eycleshymer and Schoemaker. Merkel, Cunningham, and Piersol place it at the level of the first lumbar vertebra, and Joessel places it at the same level but states that this is the position when empty. The present study places the highest level at the lower third of the tenth thoracic vertebra. Transverse Part Eycleshymer and Schoemaker reported that the lower margin of the transverse part of the duodenum varies in location from the middle of the third lumbar vertebra to the fourth lumbar disk. The average position is opposite the middle of the fourth lumbar vertebra.

window.location="http://www.ortho.hyperguides.com/"; Lumbar Disk Herniations Rahul Shah, MD Jonathan N. Grauer, MD Todd J. Albert, MD Introduction Anatomy and Pathophysiology Presentation and Evaluation Treatment Options ... References Introduction Ninety-five percent of herniated disks are located in the lumbar spine. Lumbar herniated disks present as back pain or radicular leg pain or weakness (which is commonly referred to as sciatica). This pathologic condition was described as early as the 1930s by Mixter and Bar. Most people relate the discomfort associated with a herniated disk to an acute traumatic event, but there may be a history of intermittent back pain for many months, or even years, before the onset of leg pain. Overall, this degenerative process generally presents in healthy people in the third and fourth decades of life. Anatomy and Pathophysiology Intervertebral disks are located between the vertebral bodies and are primarily composed of three biochemical components: collagen, proteoglycans, and water. Together, these components constitute 90% to 95% of the disk. However, this composition varies between the two anatomic regions; the outer annulus fibrosus is predominantly a ring of laminated collagen and the inner nucleus pulposus is gelatinous in nature ( Slide 1 Slide 1 The nucleus, which is a remnant of the developmental notochord, is predominantly composed of type II collagen. Type II collagen, along with proteoglycans, helps maintain the hydration of the nucleus, allowing the nucleus to resist compression and act as a physiologic cushion. As an individual ages, proteoglycans diminish and the nucleus loses the ability to distribute axial loads.

HERNIATED LUMBAR DISK Patients under treatment by their own physician who fail to improve after two to four weeks - refer to an Orthopedic Surgeon or Neurosurgeon for consultation and/or treatment. I. BACKGROUND Herniations occur most commonly through a posterolateral defect, but midline herniations may occur. Resulting compression of the spinal nerve root causes inflammation and pain, usually along the anatomic course of the nerve, In the lumbar spine, this most often occurs at the L4 and L5 disk levels, causing pressure on the corresponding L5 and S1 nerve roots. As a result of both mechanical and biochemical changes around the nerve root, the patient will experience pain, paresthesia, and possibly weakness in the leg or legs, usually below the knee. The rare herniations at the L1, L2 and L3 levels are usually associated with pain, paresthesia and weakness above the knee. Back pain may or may not be a presenting complaint with any herniated lumbar disk. II. DIAGNOSTIC CRITERIA A. Pertinent historical and Physical findings

Questions in The Neurology Forum are being answered by doctors from The Cleveland Clinic , consistently ranked one of the best hospitals in America. Subject: Lumbar Disk Problems Topic Area: Neuromuscular Forum: The Neurology and Neurosurgery Forum Question Posted By: Freddy on Wednesday, January 12, 2000 First of all, let me thank you for the wonderful service you provide. My question is somewhat of a personal nature concerning effects of a herniated L5-S1 disk. How common are erectile difficulties with this particular injury? I find that I have lost sensation in the penis. Will surgery to correct the disk restore full nerve function? As you can imagine, this has me quite concerned. All my neurosurgeon will say is 'Sometimes it does, sometimes it doesn't" Thank you again for your opinion. Answer Posted By: CCF Neuro[P] MD, RPS on Wednesday, January 12, 2000 Dear Freddy: Sorry to hear about your disc problem. What you are asking about is likely not due to L5/S1 herniation. The herniation would have to be pretty severe with compromise of the cord itself. The area in question is in S3/S4 if I remember correctly. The sensation and erection problem may be located somewhere else, either athroscleroisis, or sympathetic and parasympathetic derived nerves from the sacral plexus. If you have long term diabetes or use alcohol chronically these might feed into the problem. I would see a good neurologist or urologist. Sincerely

Surgery for Parkinson Herniated Lumbar Disk Excessive weight, bad postures, undue movements, improper weight lifting and other kind of traumas may weaken the inter vertebral disks. When this occurs the pulpous nucleus (spongy center) will bulge against the annulus (outer ring), or even be squeezed through it (extruded disk). If this bulged, or herniated disk, presses one of the nerves, it will produce pain going down the leg, in the distribution of the nerve, and maybe in the lower back. Sciatic pain occurs when the disk presses one of the nerves that form the sciatic nerve. Other symptoms could be weakness, tingling or numbness on the areas corresponding to the affected nerve. Sometimes bladder compromise is also present, which is made evident for urine retention and this need to be taken care as an emergency. The first steps to deal with a herniated or prolapsed lumbar disk are conservative. These include rest, analgesic and anti-inflammatory medication and in some cases physical therapy. At this point it is convenient to have some plain X-rays done, in search of some indirect evidence of the disk problem, as well as of degenerative changes on the spine.

To reach staff, make an appointment, get directions. Learn more about our residency program. Related sites Intervertebral Disk Disease What is a disk herniation? The spine is a column of bones, called vertebrae, that are separated by shock absorbing disks with elastic properties. Each vertebra has a large, central opening. All of these aligned openings form the spinal canal. The spinal cord resides in the spinal canal. At the level of each vertebra, nerves that branch from the spinal cord exit the spine through other openings called foramen. The seven uppermost vertebrae are called cervical vertebrae. Collectively, they comprise the cervical spine. The lumbar spine is composed of five vertebrae in the lower spine. The intervertebral disks (denoted as cervical disks in the cervical spine and lumbar disks in the lumbar spine) are composed of a tough outer ring and a soft center. Sometimes the soft center extrudes through weaknesses in the tough outer ring – much the same way that jelly can be squeezed from a jelly doughnut. This material can impinge on a nerve root as it branches from the spinal cord (called a radiculopathy when symptoms are present) or it can impinge on the spinal cord (called a myelopathy when symptoms are present).

Volume 24 (1) * January 2001 * Basic Science (abstract) Anatomic Considerations of the Posterolateral Lumbar Disk Region ABSTRACT Sixteen embalmed cadavers were dissected to determine the location of the lumbar nerve root and sympathetic trunk with reference to the superior border of transverse process. In the posterolateral lumbar disk region, a safe zone was found between the anterior limit of the lumbar nerve and the posterior limit of the sympathetic trunk. It has a transverse dimension of 22 mm at the T12-L1 disk region and 25 mm at the L4-L5 disk region. The only exception to this was the genitofemoral nerve running close to the lateral margin of the L2-L3 disk. The study provides an understanding of the posterolateral orientation of the lumbar nerves and sympathetic trunk. AUTHORS Reprint request: Nabil A.

They act as a cushion between the bones and allow some flexibility of the lower back. Degenerative changes or trauma may rupture the annulus fibrosus, the tough band of cartilage surrounding each disk, and disk material may bulge or herniate into the spinal canal or nerve root canal. The herniated or bulging piece of the disk or degenerative bone spur may compress the spinal cord or nerve root, causing pain in the back or "tingling and numbness" that may radiate to the buttocks, hips, groin, or legs. The pain from a bulging or herniated disk is worse on movement and may be worsened by coughing, laughing, or straining while having a bowel movement. Some patients also have weakness, clumsiness, drop foot, or walking intolerance.

management of acute lumbar disk herniation initially presenting as mechanical low back pain Volume: 22 Number: 4 Page Number: 235 Comments: Extract: Objective: To describe the clinical management with spinal manipulation of a male patient with risk factors for lumbar disk herniation initially suffering from what appeared to be mechanical low back pain that evolved into radiculopathy; also to review issues pertinent to chiropractic/manipulative management of disk herniation. Clinical Features: The patient initially suffered from unilateral low back pain and nonradicular/non-lancinating referral to the ipsilateral lower extremity. Intervention and Outcome: Disk herniation-in-evolution was included in the differential diagnosis, which was discussed with the patient, who then gave verbal informed consent for manipulative management. A day or so after the initial manipulation the presentation evolved to include S1 radiculopathy. Computed tomography, just after onset of radiculopathy, confirmed the clinical diagnosis of lumbosacral disk herniation. The patient continued with manipulative management and repeat computed tomography examination after clinical resolution about 2 months later revealed reduction in size of the apparently clinically significant herniation. Conclusion: Risk factors for the development of disk herniation should be considered when assessing patients suffering from what appears to be mechanical low back pain. The role played by manipulation in the development of disk herniation in this case was believed to be circumstantial rather than causal. Manipulation was used in the treatment of this patient over a period of approximately 2 months; after this time, clinical and partial computed tomography imaging resolution was evident. Ongoing clinical (neurologic) evaluation of patients with manifest or suspected disk hemiation is an important aspect of management. Good-quality trials of manipulation for patients with disk herniation are imperative for the chiropractic profession.

Home Lumbar spine osteoarthritis DESCRIPTION Osteoarthritis is a type of arthritis that is caused by the breakdown and eventual loss of the cartilage of one or more joints. Cartilage is a protein substance that serves as a "cushion" between the bones of the joints. Osteoarthritis is also known as degenerative arthritis. Among the over 100 different types of arthritis conditions, osteoarthritis is the most common. Osteoarthritis occurs more frequently as we age. Before age 45, osteoarthritis occurs more frequently in males. After age 55 years, it occurs more frequently in females. Osteoarthritis commonly affects the hands, feet, spine, and large weight-bearing joints, such as the hips and knees. Most cases of osteoarthritis have no known cause and are referred to as primary osteoarthritis. When the cause of the osteoarthritis is known, the condition is referred to as secondary osteoarthritis. Spinal osteoarthritis is fairly common. Osteoarthritis can develop in the joints that connect the upper part of the spine as well as in the joints of the spine itself. The bony outgrowths, or osteophytes, can be detected by X ray but usually don't change a person's appearance. Many researchers believe that lifestyle habits, including prolonged sitting, cigarette smoking, consumption of alcohol, and weight gain, contribute to the onset of spinal osteoarthritis. However, for the most part the primary cause is not known.

Home Herniated nucleus pulposus DESCRIPTION A condition in which part or all of the soft, gelatinous central portion of an intervertebral disk (the nucleus pulposus) is forced through a weakened part of the disk, resulting in back pain and leg pain caused by nerve root irritation. The spinal vertebrae are separated by cartilage disks filled with a gelatinous substance, that provide cushioning to the spinal column. These disks may herniate (move out of place) or rupture from trauma or strain, especially if degenerative changes have occurred in the disk. Radiculopathy refers to any disease affecting the spinal nerve roots. A herniated disk is one cause (but not the only cause) of radiculopathy (sciatica). Most herniation takes place in the lumbar area of the spine. Lumbar disk herniation occurs 15 times more often than cervical (neck) disk herniation, and it is one of the most common causes of lower back pain. The cervical disks are affected 8% of the time and the upper-to-mid-back (thoracic) disks only 1 to 2% of the time. Nerve roots (large nerves that branch out from the spinal cord) may become compressed resulting in neurological symptoms, such as sensory or motor changes.
