Cervical Disc Arthroplasty: A Movement-Sparing Surgical Option in Cervical Disc Degeneration

Teaser:

CLINICAL TOOLS

Abstract: Degeneration of the cervical discs is a common problem and can cause compression of cervical nerve roots and/or the spinal cord. This in turn may lead to permanent neurological injury, disability and socioeconomical impact for the patient. Surgical management typically includes either an Anterior Cervical Decompression and Fusion (ACDF) or a Posterior Decompression with or without fusion or laminoplasty. Over the past 20 years, Cervical Disc Arthroplasty (CDA) has been an increasingly viable alternative to the “Gold Standard” ACDF, after failure of conservative management in the appropriately selected patient. Single and multilevel CDA has a growing body of evidence to support its equivalency - and even superiority - to ACDF in long-term clinical outcomes.
Key Words: Cervical degenerative disc disease; Cervical Disc Replacement; Cervical Disc Arthroplasty; Radiculopathy; Myelopathy.

Cervical radiculopathy symptoms include pain, paresthesia, numbness, and weakness in a recognised dermatomal and myotomal pattern.
First-line conservative treatment for cervical radiculopathy includes physiotherapy, analgesia, and non-steroidal anti-inflammatories.
Cervical disc replacement is an evidence-supported intervention for upper extremity radiculopathy that has failed conservative treatment.
Many designs of cervical disc arthroplasty are currently available for implantation in North America.
Cervical degenerative disc disease is a common radiographic finding present in both the symptomatic and asymptomatic population.
Axial neck pain, in the absence of red flag symptoms is best managed with an active physiotherapy program and pain management strategies.
Cervical disc arthroplasty is an evidence-supported surgical option to address central or foraminal cervical stenosis at the disc level.
1 or 2-level cervical disc arthroplasty has a lower re-operation rate than anterior cervical decompression and fusion.
Cervical disc arthroplasty procedure can be performed through a 4cm incision in the front of the neck.

CLINICAL TOOLS

Abstract: Opioids are drugs with pain relieving properties; however, there is evidence that opioids are no more effective than non-opioid medications in treating low back pain (LBP), and opioid use results in higher adverse events and worse surgical outcomes. First line treatment should emphasize non-pharmacological modalities including education, self-care strategies, and physical rehabilitation. Non-steroidal anti-inflammatory drugs (NSAIDs) are generally considered an appropriate introduction into pharmacological treatment when deemed necessary. Non-opioid adjunct medications can be considered for specific features related to LBP such as neuropathic leg pain. Primary care providers should exhaust first and second line treatments before considering low-dose opioids, and only then in consultation with evidence-based clinical practice guidelines.
Key Words: Pharmacological; low back pain; radiculopathy; opioids; analgesia.

1. First line treatment for low back and radicular leg pain is non-pharmacological.
2. Second line treatment includes NSAIDs (with or without proton pump inhibitor), and muscle relaxants (3 weeks maximum), gabapentinoids and antidepressants.
3. Exhausting non-opioid analgesics includes trialing different medications within the same class and at different doses since many of these medications have wide therapeutic dose ranges.
A "start low and go slow" approach is recommended for initiating pharmacological treatments for low back and radicular leg pain, especially when using neuroleptics and antidepressants.
When treating low back pain with neuropathic leg pain, patients who fail a trial of pregabalin may tolerate gabapentin, or vice versa.
Antidepressants have a role in managing low back pain, particularly chronic, even in the absence of mood disorder.

CLINICAL TOOLS

Abstract: Lumbar disc herniation is a common cause of low back pain and radiculopathy (sciatica). Diagnosis is initially made based on history and physical examination and ruling out red flags, particularly surgical emergencies such as Cauda Equina Syndrome. A trial of conservative treatment consisting of physical rehabilitation and oral medication is usually successful for back dominant pain. When persistent radiculopathy indicates lumbar discectomy the diagnosis must be confirmed by imaging but, due to very high rates of asymptomatic disc herniation, imaging cannot replace clinical diagnosis. For disabling leg dominant pain discectomy results in faster recovery but has a similar long-term outcomes compared to conservative treatment.
Key Words: lumbar disc herniation, lower back pain, sciatica, radiculopathy.

Lumbar disc herniation is common and frequently asymptomatic.
Lumbar disc herniation may result in back pain. Much less frequently, when the adjacent nerve root is involved it can cause radiculopathy (sciatica).
Under most circumstances, the symptoms of lumbar disc herniation can be managed conservatively with physical rehabilitation and oral medications.
Red flags and surgical emergencies such as Cauda Equina Syndrome must be considered and should lead to urgent imaging and surgical referral.
Imaging, particularly MRI, has high rates of false positives and should only be used to confirm a diagnosis made based on history and physical examination.
For disabling persistent radiculopathy with good radiological correlation, surgical intervention in the form of a discectomy can be considered.
Lumbar disc herniation (LDH) is common and in most cases asymptomatic. Findings on MRI of lumbar disc herniation are not predictive of future back related disability. MRI findings should be interpreted along with history and physical exam findings to determine the appropriate diagnosis.
LDH can result in back pain and, when the adjacent nerve root is involved, radicular leg pain. The first line of treatment for back dominant pain should be education, lifestyle modification, mechanical therapy and oral medications in the form of acetaminophen, non-steroidal anti-inflammatories.
Radicular leg dominant pain may require opioids and/or epidural corticosteroid injections. The majority of patients will improve without further intervention.
For persistent symptoms of sciatica, surgical intervention can be considered. Lumbar discectomy is the most common procedure performed and has good to excellent outcomes.

CLINICAL TOOLS

Abstract: Degenerative conditions of the spine are a major cause of disability, and represent a large economic burden on the health care system. In this review, we have described some of the most common degenerative pathologies of the lumbar spine—low back pain, spinal stenosis, degenerative spondylolisthesis, lumbar disc herniation and cauda equina syndrome—and the diagnostic approach and immediate management from the perspective of the primary care physician. We have emphasized clinical pearls seen in these conditions and specific indications for surgical referral, as well as red flags that should prompt urgent referral for life-threatening entities, such as malignancy and infection.
Key Words: degenerative spine, surgery, lumbar disc herniation, spinal stenosis, spondylolisthesis, radiculopathy.

1. Evaluate for hip and knee joint pathology, and vascular pathology, especially in older patients presenting with unilateral radiating leg symptoms.
2. Spine surgery is more successful in treating leg dominant pain symptoms than back dominant mechanical pain symptoms.
3. Screen every patient presenting with a lumbar spine complaint for concomitant cervical and thoracic stenosis, in particular looking for evidence of cord compression (i.e. myelopathy). Be suspicious in patients with bilateral leg symptoms.
Clinicians should ensure that a focused history and a thorough physical examination is performed to help place patients with low back pain into several key categories: (a) nonspecific low back pain (Pattern I or II), (b) back pain potentially associated with radiculopathy leg symptoms (Pattern III) or leg claudication from structural spinal stenosis (Pattern IV), or (c) back pain potentially associated with another specific spinal cause (i.e. red flags). The history should also include assessment of psychosocial risk factors, which predict risk for chronic disabling back pain.3
Unless there are red flag symptoms or signs, routine imaging or other diagnostic tests in patients with acute nonspecific low back pain is not required.3
Diagnostic imaging and special investigations in patients with low back pain in the presence of severe or progressive neurologic deficits or when serious underlying conditions are suspected on the basis of history and physical examination.
Surgery can be helpful for patients with leg dominant symptoms (sciatica/radiculopathy, Pattern III) or leg claudication from spinal stenosis (Pattern IV). There is a limited role for surgery for back pain dominant symptoms in the absence of specific structural correlative pathology (i.e. Pattern I or II).3
Approximately 15% of patients with lumbar spinal stenosis will have concurrent cervical or thoracic canal stenosis. One must screen for the presence of upper motor neuron signs and symptoms. Degenerative lumbar stenosis always presents without upper motor findings but may occasionally have focal root compression signs.

Numbness and Paresthesias in the Elderly

Numbness and Paresthesias in the Elderly

Teaser: 

Anahita Deboo, MD, Assistant Professor of Neurology, Drexel University College of Medicine, Philadelphia, PA, USA.

The evaluation of numbness and paresthesias in geriatric patients can present a particular challenge to the primary care physician. Careful sensory examination, in combination with recognition of motor and reflex involvement, will suggest a pattern that aids in neuroanatomic localisation. This article reviews the common patterns seen in polyneuropathies, focal neuropathies, plexopathies and radiculopathies. Central nervous system etiologies also are mentioned. The differential diagnosis and further evaluation of sensory disturbances in the elderly population are discussed.
Key words: paresthesias, numbness, neuropathy, radiculopathy, plexopathy.
