Have you been diagnosed with Degenerative Disc Disease?
Are you getting conflicting information? Not sure what to do? Let us provide you with a global consultation and recommend spinal treatment options. All consultations are provided by Dr. Chiu himself.
As we age, the water and protein content of the body’s cartilage decreases. This makes the cartilage more fragile, thin and weak. Because both the discs and joints the vertebral column (facet joints) are partially composed of cartilage, these structures are increasingly subject to wear and tear or degenerative changes over time. The gradual deterioration of discs between vertebrae is referred to as degenerative disc disease.

Introduction
Often, degenerative arthritis and degenerative disk disease accompany each other. The aging process generally affects both the vertebrae and the disks. Unlike the problems associated with ruptured disks, degenerative disks are usually deteriorated, fibrous, and dehydrated, often associated with some sort of calcium deposit.
The disks are often called the body’s shock absorbers. It is the disks water content that gives them their resilience. With age, the water content in the disks decreases, the disks get smaller and lose some of their elasticity and hydration. The pain associated with degenerative disks is similar to that of arthritis, sometimes making the problem difficult to diagnose. Like arthritis, the aging process the disks go through is gradual. It is not always easy to remember exactly when the pain started.
Since the discs are like shock absorbers between the bones of the spine, they are designed to help the back stay flexible while resisting terrific forces in many different planes of motion. Each disc has two parts:
• A firm, tough outer layer (annulus fibrosus). The outer portion of this layer contains nerves. If the disc tears in this area, it can become quite painful.
• A soft, jelly-like core (nucleus puposus). This part of the disc contains proteins that can cause the tissues they touch to become swollen and tender. If these proteins leak out to the nerves of the outer layer of disc they can cause a great deal of pain.
Unlike other tissues of the body, there is very little blood supply to the disc. Once a disc is injured, it cannot repair itself, and a spiral of degeneration can set in with three stages that appear to occur over 20 to 30 years:
• Acute pain makes normal movement of the back difficult
• The bone where the injury occurred becomes relatively unstable. Over a long period of time, the patient will have back pain that comes and goes.
• The body restabilizes the injured segment of the back. The patient experiences fewer bouts of back pain.
Symptoms
The typical person with degenerative disc disease is active, otherwise healthy and in his or her 30s or 40s. Common symptoms of this condition include:
• Pain that is worse when sitting. While seated, the discs of the lower back have three times more load on them than when standing.
• Pain that gets worse when bending, lifting or twisting
• Feeling better while walking or even running than while sitting or standing for long periods of time
• Feeling better changing positions often or lying down
• Periods of severe pain that come and go. These last from a few days to a few months before getting better. They can range from nagging pain to severe, disabling pain.
• Pain can affect the low back, buttocks and thighs or the neck, depending on where the affected disc is, radiating to the arms and hands
• Numbness and tingling in the extremities
• Weakness in the leg muscles or foot drop may be a sign that there is damage to the nerve root
Several factors can cause discs to degenerate, including age. Specific factors include:
• The drying out of the disc. When we are born, the disc is about 80% water. As we age, the disc dries out and doesn't absorb shocks as well
• Daily activities and sports cause tears in the outer core of the disc. By the age of 60, most people have some degree of disc degeneration. Not everyone at that age has back pain, however.
• Injuries, which can cause swelling, soreness and instability. This can result in low back pain.
Diagnosis
To diagnose degenerative disc disease, the consultation begins with a medical history. During a physical exam, the doctor looks for limitations on movement, pain, loss of reflexes or other symptoms when the patient moves his or her spine. Other procedures that can help confirm the diagnosis include:
• X-rays, which can help rule out tumors, injuries or abnormalities
• Magnetic resonance imaging (MRI), which can be helpful in detecting damage or disease in the soft tissues, such as the discs between vertebrae or ligaments
• Computerized tomography (CT scan), which can show the shape, size and nearby structures of the spinal canal
• Myelogram, in which an opaque dye is injected into the spinal column followed by an MRI or CT scan, can show pressure on the spinal cord or nerves from herniated discs, bone spurs or tumors
• Bone scan, which can detect fractures, tumors, infections and arthritis
Conservative Non-Surgical Treatment
Here at the California Spine Institute we always consider non-surgical treatment first when managing degenerative disc disease and other neck and back ailments. Non-surgical treatment options are effective at treating the majority of neck and back disease. Some common non-surgical treatments include:
• Physical therapy – Often the first step in managing back and neck problems caused by osteoarthritis, we prescribe physical therapy, which improves flexibility and mobility and increases strength. Typical physical therapy treatments include exercise, massage, electrical stimulation, heat therapy, hydrotherapy (aquatic therapy) and others. The California Spine Institute has a fully equipped, state of the art physical rehabilitation center onsite.
• Chiropractic – Chiropractors typically adjust the spine in order to treat neck and back pain, deploying such techniques as manual manipulation (adjustment), applied pressure, and massage, of the vertebrae and joints. We provide a range of chiropractic services at our physical rehabilitation center.
• Pain management – Pain management covers a wide range of remedies, such treatments as injections, drugs and medications, spinal bracing and others.
• Alternative medicine – We have found that several non-traditional therapies including acupuncture, acupressure, yoga, biofeedback, and more are sometimes viable solutions for relieving back pain. Although supporting research is limited, many of our patients have reported relief from alternative medicine.
In addition to medical treatment, there are a variety of things you can do to delay onset and lessen the severity of spine arthritis. These include:
• Maintain a healthy weight
• Maintain proper posture
• Remain active and avoiding any extended periods of inactivity
• Quit smoking, as smoking impairs blood flow resulting in nutrient and oxygen loss in spinal tissues
• Wear comfortable, low-heeled shoes
• Sleep on a mattress of medium firmness to reduce curvature of the spine
Conventional Surgery
If conservative, non-surgical approaches aren’t successful, surgery may be needed, such as open back surgery to replace damaged discs. Until recently, this was a major operation that required general anesthesia, the dissection of muscle, removal of bone, manipulation of nerve roots, and, at times, bone fusion. Often, these types of procedures require large incisions and the manipulation bones and muscle tissue.
Conventional back surgery attempts to solve this and other back problems with extreme measures—such as removing a spinal disc or fusing parts of the spine together, so that they no longer move independent of one another, significantly decreasing the spine's mobility, or ability to move freely. Too often, considering the risks and sustained trauma, these solutions fail to relieve the patient's pain or make it and the overall spine condition worse.
It hurts just thinking about that. As you can imagine, major alterations like this to your spine (not to mention the huge access wound) take a long time to heal, several weeks or months. Full recovery, or returning to 100 percent original functionality, occurs infrequently. Also, this kind of surgery can require lengthy hospital stays, entails significant blood loss, and renders the patient vulnerable to several possible complications.
Minimally Invasive Spine Surgery
Minimally Invasive Spinal Surgery (MISS) is a procedure for decompressing nerve roots and other tissues affected by a degenerative disc disease, as well as several other types of back conditions. The term minimally invasive, of course, speaks volumes. It defines a category of procedures designed to do as little damage—to be as non-invasive and non-intrusive—as possible. Minimally invasive surgery, then, refers to surgical procedures designed to do as little collateral or malingering damage as possible.
In other words, we perform the procedure with minimal disruption to:
• The offending disc, joint, bone spurs, or facet area itself
• The entry point and access path
• The immediate area surrounding the problem area
• The patient’s overall health.
MISS is performed with micro instruments, fiber optics, lasers and digital imaging, as opposed to conventional highly invasive knives, bone saws and other equally trauma-inducing devices. Compared to conventional open back surgery, which usually entails huge incisions, displacing muscle tissue and nerve roots, and sometimes the removal of bone, MISS is without question much less traumatic. Also, it doesn’t destabilize the spine, unlike many conventional back surgeries. It can also be performed on multiple discs or other offending areas, even at widely spaced levels, during the same surgical session. Working on multiple levels with open back surgery often requires additional destructive entry wounds—far too much traumatic damage for patients to endure or recover from.
Degenerative disc disease—one of the more common back problems—for example, can cause pressure on the nerves in your spine, causing severe pain. Conventional back surgery attempts to solve this and other disc problems with extreme measures—such as removing a spinal disc or fusing parts of the spine together, so that they no longer move independent of one another. Either method significantly decreases the spine’s mobility, or ability to move freely. Too often, considering the risks and sustained trauma, these solutions fail to relieve the patient’s pain or make it and the overall spine condition worse.
As you can imagine, major alterations like this to your spine (not to mention the huge access wound) take a long time to heal, several weeks or months. Full recovery, or returning to 100 percent original functionality, occurs infrequently. Also, this kind of surgery can require lengthy hospital stays, entails significant blood loss, and renders the patient vulnerable to several possible complications.
MISS, on the other hand, is performed with very small “micro” instruments and tiny cameras inserted through a small tube. We also use x-ray, and other types of visualization technology to help guide the instruments, allowing us to “see” what we’re doing without cutting and clearing obstructing vital tissues and structures. We reach the offending disc through a very small incision. Damage to tissues and other vital structures in the immediate vicinity are, in nearly all instances, so minuscule that within a very short time the access point and path are healed, with little to no impact on the patient’s body and overall health.
After Surgery
There are numerous advantages to MISS compared to open spinal surgery.
(Note: Patients with large free fragments of disc in the spinal canal, as determined by the x-ray, cannot benefit from the endoscopic procedure, but might benefit from the arthroscopic procedure. However, the laser can shrink the bulging disc further for disc decompression.)
Some advantages are:
•Much less tissue trauma when compared to an open surgical procedure
•Hospitalization is not required, MISS is an outpatient procedure
•Faster recovery, since MISS is an outpatient procedure
•Minimal to no scarring in and around the nerves post operatively
•Earlier return to work and to daily activities
•Patients can begin an exercise program the day after surgery.
•We estimate the cost of endoscopic surgery is 40% less than conventional spine surgery
