UnitedHealthcare and the ACN do not believe I need care for Degenerative Spondylolisthesis of the Lumbar Spine
This is one of the things I have wrong with my back and United Healthcare and the ACN do not think I need care.
Degenerative Spondylolisthesis of the Lumbar Spine
Degenerative changes in the spine are often referred to those that cause the loss of normal structure and/or function. Degenerative Spondylolisthesis (DS) is a disorder that causes the forward motion (slip) of one vertebral body over the one below. The term Spondylolisthesis is formed from two Greek words; spondylo meaning vertebra and olisthesis meaning to slide on an incline. DS is most common in the lumbar spine (L4-L5) and may cause low back pain.Symptoms and Non-Operative Treatment
Typical symptoms include low back pain, muscle spasms, thigh or leg pain, and weakness. Interestingly, some patients are asymptomatic and learn of the disorder following spinal radiographs.
Low back pain associated with DS is treated non-operatively. During the acute pain phase, bedrest may be recommended for a few days. Activities involving heavy lifting and stooping are prohibited to prevent stress to the lumbar spine.
Drug Therapy
During the acute phase of low back pain, drugs may be prescribed. Some of these may include narcotics, acetaminophen, anti-inflammatory agents, muscle relaxants, and anti-depressants.
Narcotics are used on a short-term basis partially due to their addiction potential. When low back pain is caused by muscle spasm, a muscle relaxant may be prescribed. Muscles relaxants are usually used no longer than one week and have sedative effects. Depression can be a factor in chronic low back pain. Anti-depressant drugs have analgesic properties and may improve sleep.
Bracing and Physical Therapy
Other conservative non-operative treatment may include a custom-made brace. A brace is designed to reduce the loads (weight) to the lumbar spine. Physical therapy may be added to the treatment plan. Forms of therapeutic exercise including stretching may improve the flexibility of the trunk muscles. Other non-aerobic exercises may help to improve muscular endurance, coordination, strength, and facilitate weight loss. Exercise also helps to combat anxiety and depression.
Disease Progression and Neurologic Deficit
Although degenerative spondylolisthesis may cause a vertebra to slip forward, that does not always mean the disorder is progressive. The vertebral segment may be stable without any neurologic compromise. Surgery becomes a consideration when the disorder causes neurologic deficit, such as incontinence or the slip progresses. Spinal fusion and instrumentation may become a consideration if slippage exceeds three millimeters. These surgical procedures stabilize the spinal column.
The surgeon bases his/her decisions on the patient’s medical history, symptoms, radiographic findings, as well as the degree and angle of the vertebral slip. Patients who use tobacco or are obese are known to have lower rates of success with fusion. Nicotine hampers the fusion process and obesity places excessive weight on the lumbar spine.
Spinal Fusion and Instrumentation
Spinal fusion and instrumentation are combined. Spinal fusion uses the patient’s (preferred) own bone harvested from the iliac crest (pelvis). Donor bone is an option. Spinal instrumentation uses medically designed implants such as screws and cages. The implant(s) holds the vertebral segment secure facilitating fusion. Instrumentation provides more rapid pain relief, recovery, and may eliminate the need for bracing following surgery. Two surgical procedures that utilize spinal fusion and instrumentation are termed Anterior Lumbar Interbody Fusion (ALIF) and Posterior Lumbar Interbody Fusion (PLIF). The difference between the two procedures is the surgical approach to treat the disorder (front or rear).
In Conclusion
Although aging adults can expect some degenerative processes to occur in their spines, this certainly does not point to a future facing disability. In general, spondylolisthesis only affects a small percentage of the population. Overall, most degenerative disorders of the spinal can be treated non-surgically with good outcomes.

In this thorough overview of Degenerative Spondylolisthesis, Dr. Lowe describes the importance of the correlation of the patient’s symptoms, the physical examination and the radiographic findings. As he states, many patients with the radiographic finding of DS are successfully treated nonoperatively. Unless there is significant neurologic impairment, a trial of conservative care is generally warranted. If the patient’s symptoms are persistent, then surgical intervention may be appropriate. In terms of a surgical option, decompression (to address nerve related symptoms) and stabilization/fusion are the two most often considered components. Depending upon the patient’s pattern of symptomatology and radiographic findings decompression alone, fusion alone, or a combined decompression and fusion may be considered by the treating surgeon. As described by Dr. Lowe, instrumentation is generally used in conjunction with fusion to provide initial stability to the involved area and to optimize fusion success rates.
