Use of cervical spine manipulation under anesthesia for management of cervical disk herniation, cervical radiculopathy, and associated cervicogenic headache syndrome

OBJECTIVE: To demonstrate the benefits of cervical spine manipulation with the patient under anesthesia as an approach to treating a patient with chronic cervical disk herniation, associated cervical radiculopathy, and cervicogenic headache syndrome. CLINICAL FEATURES: The patient had neck pain with radiating paresthesia into the right upper extremity and incapacitating headaches and had no response to 6 months of conservative therapy. Treatment included spinal manipulative therapy, physical therapy, anti-inflammatory medication, and acupuncture. Magnetic resonance imaging, electromyography, and somatosensory evoked potential examination all revealed positive diagnostic findings. INTERVENTION AND OUTCOME: Treatment included 3 successive days of cervical spine manipulation with the patient under anesthesia. The patient had immediate relief after the first procedure. Her neck and arm pain were reported to be 50% better after the first trial, and her headaches were better by 80% after the third trial. Four months after the last procedure the patient reported a 95% improvement in her overall condition. CONCLUSION: Cervical spine manipulation with the patient under anesthesia has a place in the chiropractic arena. It is a useful tool for treating chronic discopathic disease complicated by cervical radiculopathy and cervicogenic headache syndrome. The beneficial results of this procedure are contingent on careful patient selection and proper training of qualified chiropractic physicians.     

Chiropractic care of a patient with vertebral subluxations and unsuccessful surgery of the cervical spine

OBJECTIVE: The chiropractic care of a patient with vertebral subluxations, neck pain, and cervical radiculopathy after a cervical diskectomy is described. CLINICAL FEATURES: A 55-year-old man had neck pain and left upper extremity radiculopathy after unsuccessful cervical spine surgery. INTERVENTION AND OUTCOME: Contact-specific, high-velocity, low-amplitude adjustments (i.e., Gonstead technique) were applied to sites of vertebral subluxations. Rehabilitation exercises were also used as adjunct to care. The patient reported a decrease in neck pain and left arm pain after chiropractic intervention. The patient also demonstrated a marked increase in range of motion (ROM) of the left glenohumeral articulation. CONCLUSION: The chiropractic care of a patient with neck pain and left upper extremity radiculopathy after cervical diskectomy is presented. Marked resolution of the patient's symptoms was obtained concomitant with a reduction in subluxation findings at multiple levels despite the complicating history of an unsuccessful cervical spine surgery. This is the first report in the indexed literature of chiropractic care after an unsuccessful cervical spine surgery.     

Management of acute lumbar disk herniation initially presenting as mechanical low back pain.

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/nonlancinating 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 herniation is an important aspect of management. Good-quality trials of manipulation for patients with disk herniation are imperative for the chiropractic profession.     

Cox decompression chiropractic manipulation of a patient with postsurgical lumbar fusion: a case report

OBJECTIVE: The purpose of this case report is to describe a patient with an L5/S1 posterior surgical fusion who presented to a chiropractic clinic with subsequent low back and leg pain and was treated with Cox decompression manipulation. CLINICAL FEATURES: A 55-year-old male postal clerk presented to a private chiropractic practice with complaints of pain and spasms in his low back radiating down the right buttock and leg. His pain was a 5 of 10, and Oswestry Disability Index score was 18%. The patient reported a previous surgical fusion at L5/S1 for a grade 2 spondylolytic spondylolisthesis. Radiographs revealed surgical hardware extending through the pedicles of L5 and S1, fusing the posterior arches. INTERVENTION AND OUTCOME: Treatment consisted of ultrasound, electric stimulation, and Cox decompression manipulation (flexion distraction) to the low back. After 13 treatments, the patient had a complete resolution of his symptoms with a pain score of 0 of 10 and an Oswestry score of 2%. A 2-year follow-up revealed continued resolution of the patient's symptoms. CONCLUSIONS: Cox chiropractic decompression manipulation may be an option for patients with back pain subsequent to spinal fusion. More research is needed to verify these results.     

Chiropractic rehabilitation of a patient with S1 radiculopathy associated with a large lumbar disk herniation

OBJECTIVE: To describe the nonsurgical treatment of acute S1 radiculopathy from a large (12 x 12 x 13 mm) L5-S1 disk herniation. CLINICAL FEATURES: A 31-year-old man presented with severe lower back pain and pain, paresthesia, and plantar flexion weakness of the left leg. His symptoms began 5 days before the initial visit and progressed despite nonsteroidal anti-inflammatory drugs and analgesic medication. An absent left Achilles reflex, left S1 dermatome hypesthesia, and left gastrocnemius/soleus weakness was noted. Magnetic resonance imaging demonstrated a large L5-S1 disk herniation. INTERVENTION AND OUTCOME: Initial treatment of this patient included McKenzie protocol press-ups to reduce and centralize symptoms, nonloading exercise for cardiovascular fitness, and lower leg isotonic exercises to prevent atrophy. Counseling was provided to reduce abnormal illness behavior risk. Later, flexion distraction and side-posture manipulation were provided to improve joint function. Sensory motor training, trunk stabilization exercises, and trigger point therapy were also used. He returned to modified work 27 days after symptom onset. A follow-up, comparative magnetic resonance imaging (MRI) study was unchanged. He was discharged as symptomatic (zero rating on both the Oswestry and numerical pain scales) after 50 days and 20 visits, although the left S1 reflex remained absent. Reassessment 169 days later revealed neither significant symptoms nor lifestyle restrictions. CONCLUSION: This case demonstrates the potential benefit of a chiropractic rehabilitation strategy by use of multimodal therapy for lumbar radiculopathy associated with disk herniation.     

Lumbar intraspinal synovial cyst containing gas as a cause for low-back pain

OBJECTIVE: To discuss intraspinal synovial cysts caused by degenerative changes involving the posterior articular facets in the lumbar spine and to provide differential considerations for patients with low-back pain. Clinical Features: A 70-year-old man with low-back and gluteal pain demonstrating eventual progression of radiating pain into the left thigh, calf, ankle, and foot over a 5-month period. Radiographs of the lumbar spine revealed mild degenerative disk disease at L5-S1 with associated vacuum phenomena of the L5 disk. Degenerative osteophytes were present at L3, L4, and L5. Moderate posterior joint arthrosis was evident at L4-L5 and L5-S1. Computed tomography and magnetic resonance imaging studies revealed an intraspinal gas-containing synovial cyst at the left lateral aspect of the central canal at the level of the left L4-L5 facet articulation. Intervention and Outcome: The patient underwent surgical excision of the synovial cyst with remission of symptoms. CONCLUSION: Gas-containing intraspinal synovial cysts can be a significant finding and a causative factor in patients with low-back pain and pain radiating into the lower extremities. Both computed tomography and magnetic resonance imaging are important in defining intraspinal synovial cysts as a cause of back pain in patients whose low-back pain does not respond to chiropractic care.     

T2 radiculopathy: A differential screen for upper extremity radicular pain

Radicular pain in the upper extremity can have a cervical origin terminating at the cervicothoracic junction (C8, T1). Review of the literature suggests cutaneous representations of T2 nerve root to the axilla, posteromedial arm, and lateral forearm, suggesting yet another source of upper extremity radicular pain. A 53-year-old female experienced insidious right upper thoracic pain radiating into the right axilla, upper arm, and lateral forearm (10/10 numerical pain rating scale (NPRS)) of 1-week duration. Medical referral suggested cervical radiculopathy, however, cervical spine examination was unremarkable. She presented with mechanical dysfunction of C8, T1; T1, T2; and T2, T3 vertebral segments with restricted cervical extension. Firm compression over the right lateral aspect of the second and third thoracic vertebrae reproduced her symptoms markedly. There was a predominance of right axillary pain. Cervical extension reproduced local upper thoracic pain. Nine treatment visits for a period of 3 weeks addressed mechanical dysfunction at the cervicothoracic junction and upper thoracic region, comprising manual therapy, corrective exercise, and pain modalities. Reduction of local tenderness, and radiating axillary and right arm pain was observed (2/10 NPRS), with improved cervical extension. The second thoracic intercostal nerve and the adjoining intercostobrachial nerve, medial antebrachial cutaneous nerve, and the posterior brachial cutaneous branch of the radial nerve are speculated to be potential symptom mediators. They have a representation to the axilla, medial and posterior arm, and lateral forearm – a representation supporting the speculation of upper extremity radicular symptoms following mechanical dysfunction of the upper thoracic vertebrae.     

Disorders in the Lower Cervical Spine. A Cause of Unilateral Headache?

Various pathoanatomical disorders may underlie cervicogenic headache. We present a patient who, after 15 years of unilateral headache and neck pain, developed radiating pain in the ipsilateral (left) arm. Cervical myelography demonstrated herniation of the C6-C7 intervertebral disc with involvement of the left C7-root. After decompression of this root, with disappearance of the radiating symptoms, the left-sided unilateral headache also disappeared. The follow-up time is 38 months.     

Lumbar extension exercises in conjunction with mechanical traction for the management of a patient with a lumbar herniated disc

ABSTRACT

Low back pain resulting from lumbar disc herniation is a common reason for referral for physical therapy. There is no evidence to support the management of lumbar disc herniation and derangement using mechanical traction combined with lumbar extension exercises. Therefore, the purpose of this case report was to describe and discuss the use of mechanical traction in conjunction with lumbar extension exercises for a patient with a lumbar herniated disc. The patient was a 49-year-old male referred to physical therapy with a medical diagnosis of a lumbar herniated disc at L5-S1 with compression of the L5 nerve root confirmed by MRI. The patient's chief complaint was pain over the left lumbosacral and central lumbar region with radiating pain into the left buttock accompanied by numbness and tingling in the left lower leg and foot. The patient was seen for a total of 14 visits. The first 5 days (2 weeks) of therapy consisted of lumbar extension exercises. For the following nine visits (over a 3-week period), mechanical traction was added as an adjunct to the extension exercises. Outcome measures included the Oswestry Disability Questionnaire, Back Pain Function Scale (BPFS), and the Numeric Pain Rating Scale (NPRS). Results from initial evaluation to discharge (Oswestry: 36% to 0%; BPFS: 33/60 to 57/60; NPRS: 7/10 to 0/10) demonstrated that the patient no longer experienced low back pain and improved in terms of functional status and pain-related disability. The patient no longer complained of numbness and tingling in the left lower extremity and the goals for the patient had been attained. The data from this case report suggests lumbar extension exercises in conjunction with mechanical traction facilitated the patient's improvement in pain and return to prior level of function.     

Concomitance of fibromyalgia syndrome and cervical disc herniation

[Purpose] Fibromyalgia syndrome (FMS) and cervical disc herniation (CDH) are a common diseases commonly encountered in physical therapy clinics. There are also patients who have both of these diseases. In this study we aim to investigated whether FMS is a risk factor for cervical disc herniation and the frequency of their coincident occurrence. [Subjects and Methods] Thirty-five patients having a primary FMS diagnosis according to the American Rheumatism Association criteria are taken into consideration and a control group were the subjects of this study. The two groups were compared with respect to cervical disc hernia using cervical region MRI. [Results] The distribution of disc hernia of 6 fibromyalgia patients who had cervical discopathy was: 16.6% C2–3, 16.6% C5–6, 16.6% C6–7, 33.3% C4–5, C5–6 (two levels in two patients) and 16.6% C4–5, C5–6, C7–1 (three levels in one patient) . The herniation directions were given as: central in 5 levels, right paramedian in 1 level, and left paramedian disc hernia in 1 level. There were 4 cervical disk hernia in the control group. The herniation direction were central in two, right paramedian in one, and left paramedian in one patient. [Conclusion] In this study, the existence of cervical disc herniation in fibromyalgia patients was found to be not different from the normal population.Key words: Primary fibromyalgia syndrome, Cervical disc herniation, Fibromyalgia     

Recognition of prodromal cervical spondylotic myelopathy presenting in a U.S. Veteran referred to chiropractic for acute thoracic pain: A case report

ObjectiveTo highlight a patient who was referred to a VA chiropractic clinic for thoracic pain and upon physical exam was found to be myelopathic, subsequently requiring surgery.Clinical featuresA 58-year-old male attended a telephone interview with the VA chiropractic clinic for thoracic pain of 4 months duration; he denied neck pain, upper extremity symptoms or clumsiness of the feet or hands. At his in-person visit, he acknowledged frequently dropping items. The physical examination revealed signs of myelopathy including positive Hoffman's bilaterally, 3+ brisk patellar reflexes, and 5+ beats of ankle clonus bilaterally. He also had difficulty walking heel/toe.Intervention and outcomeCervical and thoracic radiographs were ordered and a referral was placed to the Physical Medicine and Rehabilitation (PM&R) Clinic for evaluation of the abnormal neurologic exam and suspicion of cervical spondylotic myelopathy (CSM). He was treated for 2 visits in the chiropractic clinic for his thoracic pain, with resolution of thoracic symptoms. No treatment was rendered to the cervical spine.The PM&R physician ordered a cervical MRI which demonstrated severe central canal stenosis and increased T2 signal within the cord at C5–C6, representing myelopathic changes. The PM&R specialist referred him to Neurosurgery which resulted in a C5-6, C6-7 anterior cervical discectomy and fusion.ConclusionThe importance of physical examination competency and routine thoroughness cannot be overstated. Swift identification of pathologic signs by the treating chiropractor resulted in timely imaging and surgical intervention.     

Chiropractic treatment of postsurgical neck syndrome with mechanical force, manually assisted short-lever spinal adjustments

OBJECTIVE: To describe a case of postsurgical neck pain, after multiple spinal surgeries, that was successfully treated by chiropractic intervention with instrumental adjustment of the cervical spine. CLINICAL FEATURES: A 35-year-old woman had chronic neck pain for over 5 years after two separate surgeries of the cervical spine: a diskectomy at C3/4 and a fusion at C5/6. Surgeries were performed 6 months apart in an attempt to resolve persistent neck pain and spasm of the cervical musculature. Neither surgery was effective in relieving the patient's pain. Five years after the second surgery, a third surgery was recommended by the patient's physicians to alleviate the chronic pain. The patient sought chiropractic evaluation of her condition to avoid further surgical intervention. INTERVENTION AND OUTCOME: The patient was treated with conservative instrumental chiropractic manipulation, consisting of mechanical force, manually assisted short-lever spinal adjustments rendered with an Activator Adjusting Instrument (AAI) II. She comfortably tolerated the treatment and responded favorably to this therapy. All chronic symptoms had resolved within 30 days of instituting the chiropractic instrumental adjustments with an AAI. More interestingly, longitudinal examination over the next 2 years showed that the patient experienced no residual effects or further recurrences of her previous chronic problem after her initial course of chiropractic care. CONCLUSION: Chiropractic treatment of postsurgical neck syndrome may be effectively treated, in certain cases, by mechanical force, manually assisted adjusting procedures with an AAI. The use of instrumental adjustment methodology may provide chiropractic physicians with an effective alternative to manual manipulation in those cases in which the patient's surgical history or presenting symptoms make forceful manipulation of the spine, particularly performed at end range, inappropriate. This approach may be contemplated by physicians faced with managing this type of condition. Further study should be made in this regard, in an academic research setting, to determine the safest and most effective approaches to managing postsurgical patients in a chiropractic setting.     

Treatment of cervical radiculopathy with flexion distraction

OBJECTIVE: To discuss the nonsurgical treatment of a cervical disk herniation with flexion distraction manipulation. CLINICAL FEATURES: A case study of cervical disk syndrome with radicular symptoms is presented. Magnetic resonance imaging revealed a large C5-C6 disk herniation. Degenerative changes at the affected level were demonstrated on cervical spine plain film radiographs. INTERVENTION AND OUTCOME: The patient received treatment in the form of flexion distraction manipulation and adjunctive therapies. A complete resolution of the patient's subjective complaints was achieved. CONCLUSION: Flexion distraction has been a technique associated with musculoskeletal conditions of the lumbar spine. Flexion distraction applied to the cervical spine might be an effective therapy in the treatment of cervical disk herniations. Although further controlled studies are needed, treatment of cervical disk syndromes with flexion distraction might be a viable form of conservative care.     

Pain, disability, and satisfaction outcomes and predictors of outcomes: a practice-based study of chronic low back pain patients attending primary care and chiropractic physicians

BACKGROUND: Few studies exist on the prognostic value of demographic, clinical, or psychosocial factors on long-term outcomes for patients with chronic low back pain. OBJECTIVE: This study reports on long-term pain and disability outcomes for patients with chronic low back pain, evaluates predictors of long-term outcomes, and assesses the influence of doctor type on clinical outcome. METHODS: Sixty chiropractic (DC) and 111 general practice (MD) physicians participated in data collection for a prospective, longitudinal, practice-based, observational study of ambulatory low back pain of mechanical origin. The primary outcomes, measured at 6 months and 12 months, were pain (by using the Visual Analog Scale), and functional disability (by using the Revised Oswestry Disability Questionnaire). Satisfaction was a secondary outcome. RESULTS: Overall, long-term pain and disability outcomes were generally equivalent for patients seeking care from medical or chiropractic physicians. Medical and chiropractic care were comparable for patients without leg pain and for patients with leg pain above the knee. However, an advantage was noted for chronic chiropractic patients with radiating pain below the knee after adjusting for baseline differences in patient and complaint characteristics between MD and DC cohorts (adjusted differences = 8.0 to 15.2; P <.002). A greater proportion of chiropractic patients were satisfied with all aspects of their care (P =.0000). The strongest predictors of primary outcomes included an interaction of radiating pain below the knee with provider type and baseline values of the outcomes. Income, smoking, comorbidity, and chronic depression were also identified as predictors of outcomes in this study. CONCLUSION: Chiropractic care compared favorably to medical care with respect to long-term pain and disability outcomes. Further study is required to explore the advantage seen for chiropractic care in patients with leg pain below the knee and in the area of patient satisfaction. Identification of patient and treatment characteristics associated with better or worse outcomes may foster changes in physicians' practice activities that better serve these patients' needs.     

Case study: acceleration/deceleration injury with angular kyphosis

OBJECTIVE: To discuss the case of a patient who received upper cervical chiropractic care after trauma-induced arcual kyphosis in the cervical spine. A practical application of conservative management for posttrauma cervical spine injury in the private office setting is described. Clinical Features: A 17-year-old female patient suffered an unstable C3/C4 motor segment after a lateral-impact motor vehicle collision. Additional symptoms on presentation included vertigo, tinnitus, neck and shoulder pain, and confusion. Intervention and Outcome: Conservative management consisted exclusively of upper cervical-specific adjustments guided by radiographic analysis and paraspinal bilateral skin temperature differential analysis of the cervical spine. During 10 weeks of care and 22 office visits, all symptoms subsided and the instability of C3/C4 motor segment appeared to be completely resolved. CONCLUSION: This study provides support for the use of upper cervical chiropractic management in cervical spine trauma cases. The clinical work-up consisted of physical examination, radiographic analysis, computer-administered and scored cognitive function testing, and audiometric examination. After conservative care, these examinations were repeated and demonstrated that the objective findings concurred with the subjective improvements reported by the patient.     

Immediate and lasting effects of a thoracic spine manipulation in a patient with signs of cervical radiculopathy and upper extremity hyperalgesia: A case report

Patients with cervical radiculopathy (CR) may present with accompanying symptoms of hyperalgesia, allodynia, heaviness in the arm, and non-segmental pain that do not appear to be related to a peripheral spinal nerve. These findings may suggest the presence of central or autonomic nervous system involvement, requiring a modified management approach. The purpose of this case report is to describe the treatment of a patient with signs of CR and upper extremity (UE) hyperalgesia who had a significant decrease in her UE pain and hypersensitivity after a single thoracic spine manipulation (TSM). A 48-year-old female presented to physical therapy with acute neck pain radiating into her left UE that significantly limited her ability to sleep and work. After a single TSM, the patient demonstrated immediate and lasting reduction in hyperalgesia, hypersensitivity to touch, elimination of perceived heaviness and coldness in her left UE, and improved strength in the C6-8 myotome, allowing for improved functional activity capacity and tolerance to a multi-modal PT program. Based on these results, clinicians should consider the early application of TSM in patients with CR who have atypical, widespread, or severe neurological symptoms that limit early mobilization and tolerance to treatment at the painful region.     

A new 3-point bending traction method for restoring cervical lordosis and cervical manipulation: a nonrandomized clinical controlled trial

OBJECTIVE: To evaluate a new 3-point bending type of cervical traction. DESIGN: Nonrandomized controlled trial of prospective, consecutive patients compared with control subjects. Follow-up patient data were obtained at 3 and 15(1/2) months, and 8 1/10 months for controls. SETTING: Data were collected at a spine clinic in Nevada. PATIENTS: Volunteer subjects consisted of 30 patients and 24 controls. Subjects had cervicogenic pain (neck pain, headaches, arm pain, and/or numbness). Subjects were included if their Ruth Jackson radiographic stress lines measured less than 25 degrees but were excluded if they had suspected disk herniation or canal stenosis. All subjects completed the first follow-up examinations, and 25 of 30 patients completed the long-term follow-up examination. INTERVENTIONS: Spinal manipulation for pain and a new form of 3-point bending cervical traction to improve lordosis. Cervical manipulation was provided for the first 3 to 4 weeks of treatment. Traction treatment consisted of 3 to 5 sessions per week for 9 +/- 1 weeks. MAIN OUTCOMES MEASURES: Besides pain visual analog scale (VAS) ratings, pre- and posttreatment lateral cervical radiographs were analyzed. RESULTS: Control subjects reported no change in the pain VAS ratings and had no statistically significant change in segmental or global radiographic alignment. For the traction group, VAS ratings were 4.3 pretreatment and 1.6 posttreatment. Traction group radiographic measurements showed statistically significant improvements (P <.008 in all instances of statistical significance), including anterior head weight bearing (improved 6.2mm), Cobb angle at C2-7 (improved 12.1 degrees ), and angle between posterior tangents at C2-7 (improved 14.2 degrees ). For the treatment group, at 15(1/2)-month follow-up, only minimal loss of C2-7 lordosis (3.5 degrees ) was observed. CONCLUSIONS: Sagittal cervical traction with transverse load at midneck (2-way cervical traction) combined with cervical manipulation can improve cervical lordosis in 8 to 10 weeks as indicated by increases in segmental and global cervical alignment. Magnitude of lordosis at C2-7 remained stable at long-term follow-up.     

Imaging the back pain patient

Imaging is an integral part of the clinical examination of the patient with back pain; it is, however, often used excessively and without consideration of the underlying literature. The primary role of imaging is the identification of systemic disease as a cause of the back or limb pain; magnetic resonance imaging (MRI) excels at this. Systemic disease as a cause of back or limb pain is, however, rare. Most back and radiating limb pain is of benign nature, owing to degenerative phenomena. There is no role for imaging in the initial evaluation of the patient with back pain in the absence of signs or symptoms of systemic disease. When conservative care fails, imaging may be undertaken with due consideration of its risks: labeling the patient as suffering from a degenerative disease, cost, radiation exposure, and provoking unwarranted minimally invasive or surgical intervention. Imaging can well depict disc degeneration and disc herniation. Imaging can suggest the presence of discogenic pain, but the lack of a pathoanatomic gold standard obviates any definitive conclusions. The imaging natural history of disc herniation is resolution. There is very poor correlation between imaging findings of disc herniation and the clinical presentation or course. Psychosocial factors predict functional disability due to disc herniation better than imaging. Imaging with MRI, computed tomography (CT), or CT myelography can readily identify central canal, lateral recess, or foraminal compromise. Only when an imaging finding is concordant with the patient's pain pattern or neurologic deficit can causation be considered. The zygapophysial (facet) and sacroiliac joint are thought to be responsible for axial back pain, although with less frequency than the disc. Imaging findings of the structural changes of osteoarthritis do not correlate with pain production. Physiologic imaging, either with single-photon emission CT bone scan, heavily T2-weighted MRI sequences (short-tau inversion recovery), or gadolinium enhancement, can detect inflammation and are more predictive of an axial pain generator.     

Electrodiagnostics for low back pain

Low back pain with radiating pain to the hip, buttock, or limb is the most common reason for electrodiagnostics referral. Electrodiagnostics is used to assess for lumbosacral radiculopathy potentially underlying low back pain. It serves as an extension of the clinical history and physical examination, and complements neuroimaging. Common low back pathologies amenable to electrodiagnostic evaluation include lumbosacral disk herniation and spinal stenosis. Electrodiagnostics may aid in the decision-making process when considering surgical management, and may aid in patient selection. The usefulness of electrodiagnostics is maximized when performed for the appropriate patient, and when the findings are properly interpreted.
