There are multiple techniques used in the diagnosis of spondylosis, these are;

- Cervical Compression Test, a variant of Spurling's test, is performed by laterally flexing the patient's head and placing downward pressure on it. Neck or shoulder pain on the ipsilateral side (i.e. the side to which the head is flexed) indicates a positive result for this test. However it should be noted that a positive test result is not necessarily a positive result for spondylosis and as such additional testing is required.

- Lhermitte sign: feeling of electrical shock with patient neck flexion

- Reduced range of motion of the neck, the most frequent objective finding on physical examination

- MRI and CT scans are helpful for pain diagnosis but generally are not definitive and must be considered together with physical examinations and history.

Wobblers is definitively diagnosed by x-ray, nuclear scintography or bone scan. X-rays will show channel widening or filling the easiest and are often most cost effective to horse owners. X-rays will also show any structural anomaly, arthritis, facet remodeling, or bone spurs present. Preliminary diagnosis can be made by ultrasound but x-rays are needed to measure the true depth of facet involvement. For extent of damage to associated structures, veterinarians may opt to have the horse undergo a bone scan or nuclear scintography.

Historically, the detection of spinal misalignments (subluxations) by the chiropractic profession has relied on X-ray findings and physical examination. At least 2 of the following 4 physical signs and/or symptoms must be documented to qualify for reimbursement:

- Pain and tenderness

- Asymmetry/misalignment

- Range of motion abnormality

- Tissue/tone changes

It has been proposed that a vertebral subluxation can negatively affect general health by altering the neurological communication between the brain, spinal cord and peripheral nervous system. Although individuals may not always be symptomatic, straight chiropractors believe that the presence of vertebral subluxation is in itself justification for correction via spinal adjustment.

Chiropractic treatment of vertebral subluxation focuses on delivering a chiropractic adjustment which is a high velocity low amplitude (HVLA) thrust to the dysfunctional spinal segments to help correct the chiropractic subluxation complex. Spinal adjustment is the primary procedure used by chiropractors in the adjustment. Adjustment/manipulation has been shown to help with low back pain, neck pain and tension type headaches, but further studies are inconclusive on the use of spinal manipulation outside the treatment of neuromusculoskeletal disorders.

Joint stability is easily evaluated by the use of flexion and extension lateral x-ray views of the spine.

A summary of part of the DRE tables () give a guide as to the implications of the joint instability. If either translation or angular change is determined from flexion to extension to the degree shown in the table below, then Category IV instability is present. This would mean that 20% to 23% “whole person impairment” is present at each level where this if found. In calculating the total whole person impairment it is NOT merely the case of adding the percentages. This calculation is best left to your health care provider. See also Joint stability.

Translation is a gliding motion where one bone of a joint glides over its neighbour.

The malpositioning seen on radiography may not cause any symptoms at all. If there are related symptoms, however, therapeutic options include chiropractic care, physical therapy and nerve block injections. As a last resort, decompressive laminectomy may be attempted to relieve pain symptoms and remove the abnormally enlarged portions of bone.

Treatment is usually conservative in nature. Patient education on lifestyle modifications, chiropractic, nonsteroidal anti-inflammatory drugs (NSAIDs), physical therapy, and osteopathic care are common forms of manual care that help manage such conditions. Other alternative therapies such as massage, trigger-point therapy, yoga and acupuncture may be of limited benefit. Surgery is occasionally performed.

Many of the treatments for cervical spondylosis have not been subjected to rigorous, controlled trials. Surgery is advocated for cervical radiculopathy in patients who have intractable pain, progressive symptoms, or weakness that fails to improve with conservative therapy. Surgical indications for cervical spondylosis with myelopathy (CSM) remain somewhat controversial, but "most clinicians recommend operative therapy over conservative therapy for moderate-to-severe myelopathy" (Baron, M.E.).

Physical therapy may be effective for restoring range of motion, flexibility and core strengthening. Decompressive therapies (i.e. manual mobilization, mechanical traction) may also help alleviate pain. However, physical therapy and osteopathy cannot "cure" the degeneration, and some people view that strong compliance with postural modification is necessary to realize maximum benefit from decompression, adjustments and flexibility rehabilitation.

It has been argued, however, that the cause of spondylosis is simply old age, and that posture modification treatment is often practiced by those who have a financial interest (such as Worker's Compensation) in proving that it is caused by work conditions and poor physical habits. Understanding anatomy is the key to conservative management of spondylosis.

Because there are various causes for back injuries, prevention must be comprehensive. Back injuries are predominant in manual labor so the majority low back pain prevention methods have been applied primarily toward biomechanics Prevention must come from multiple sources such as education, proper body mechanics, and physical fitness.

In 1977, Dyck and Doyle reported on the bicycle test, a simple procedure in which the patient is asked to pedal on a stationary bicycle. If the symptoms are caused by peripheral vascular disease, the patient will experience claudication, a sensation of not getting enough blood to the legs; if the symptoms are caused by lumbar stenosis, symptoms will be relieved when the patient is leaning forward while bicycling. Although diagnostic progress has been made with newer technical advances, the bicycle test remains an inexpensive and easy way to distinguish between claudication caused by vascular disease and spinal stenosis.

MRI is the preferred method of diagnosing and evaluating spinal stenosis of all areas of the spine, including cervical, thoracic and lumbar. MRI is useful to diagnose cervical spondylotic myelopathy (degenerative arthritis of the cervical spine with associated damage to the spinal cord). The finding of degeneration of the cervical spinal cord on MRI can be ominous; the condition is called myelomalacia or cord degeneration. It is seen as an increased signal on the MRI. In myelopathy (pathology of the spinal cord) from degenerative changes, the findings are usually permanent and decompressive laminectomy will not reverse the pathology. Surgery can stop the progression of the condition. In cases where the MRI changes are due to Vitamin B-12 deficiency, a brighter prospect for recovery can be expected.

The straight leg raise may be positive, as this finding has low specificity; however, it has high sensitivity. Thus the finding of a negative SLR sign is important in helping to "rule out" the possibility of a lower lumbar disc herniation. A variation is to lift the leg while the patient is sitting. However, this reduces the sensitivity of the test.

T2 weighted MRI in neutral (A) and linear traction (B) of a seven-year-old Doberman with a two-year history of cervical pain treated with NSAIDs and presented acutely tretraplegic: A C6-C7 and C5-C6 traction responsive myelopathy are evident on MRI. The spinal-cord hyperintensity seen at the C5-C6 is suggestive of chronic lesion and most likely responsible for the chronic history of cervical pain, while the C5-C6 lesion was most likely responsible for the acute tetraplegia.

Same dog (A) treated with double implant (B) three days after surgery: The dog became ambulatory three days after surgery. Four weeks after surgery, it had ataxia without conscious proprioceptive deficits, and three months after surgery, the dog was neurologically normal. The owner reported it had been two years since the dog was able to hold its neck in an elevated position.

The diagnosis of spinal stenosis involves a complete evaluation of the spine. The process usually begins with a medical history and physical examination. X-ray and MRI scans are typically used to determine the extent and location of the nerve compression.

A spinal tap is performed in the low back with dye injected into the spinal fluid. X-Rays are performed followed by a CT scan of the spine to help see narrowing of the spinal canal.

This is a very effective study in cases of lateral recess stenosis. It is also necessary for patients in which MRI is contraindicated, such as those with implanted pacemakers.

There are two tests that can provide a definite diagnosis of myelomalacia; magnetic resonance imaging (MRI), or myelography. Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to visualize the internal structure of the body used in the diagnosing of myelomalacia. Certain MRI findings can detect where bone density and matter has been lost in people with spinal cord injuries. Diffuse hyperintensity appreciated on T2-weighted imaging of the spinal cord can be an indication of the onset or progression of myelomalacia

Vertebral fractures of the thoracic vertebrae, lumbar vertebrae or sacrum are usually associated with major trauma and can cause spinal cord injury that results in a neurological deficit.

The vertebral column, also known as the backbone or spine, is part of the axial skeleton. The vertebral column is the defining characteristic of a vertebrate, in which the notochord (a flexible rod of uniform composition) found in all chordates has been replaced by a segmented series of bones—vertebrae separated by intervertebral discs. The vertebral column houses the spinal canal, a cavity that encloses and protects the spinal cord.

There are about 50,000 species of animals that have a vertebral column. The human vertebral column is one of the most-studied examples.

A spinal fracture, also called a vertebral fracture or a broken back, is a fracture affecting the vertebrae of the spinal column. Most types of spinal fracture confer a significant risk of spinal cord injury. After the immediate trauma, there is a risk of spinal cord injury (or worsening of an already injured spine) if the fracture is "unstable", that is, likely to change alignment without internal or external fixation.

Retrolisthesis may lead to symptoms of greatly varying intensity and distribution. This is because of the variable nature of the impact on nerve tissue and of the mechanical impact on the spinal joints themselves.

Structural instability may be Experienced as a local uneasiness through to a more far reaching structural compensatory distortion involving the whole spine. If the joints are stuck in a retrolisthesis configuration there may also be changes to range of motion.

Pain may be experienced as a result of irritation to the sensory nerve roots by bone depending on the degree of displacement and the presence of any rotatory positioning of the individual spinal motion segments. The soft tissue of the disc is often caused to bulge in retrolistheses. These cannot be determined by plain films, as the x-ray passes through the soft tissue. A study by Giles et al., stated that Sixteen of the thirty patients (53%) had retrolisthesis of L5 on S1 ranging from 2–9 mm; these patients had either intervertebral disc bulging or protrusion on CT examination ranging from 3–7 mm into the spinal canal. Fourteen patients (47%) without retrolisthesis (control group) did not show any retrolisthesis and the CT did not show any bulge/protrusion. On categorizing x-ray and CT pathology as being present or not, the well positioned i.e. true lateral plain x-ray film revealed a sensitivity and specificity of 100% ([95% Confidence Interval. = [89%–100%]) for bulge/protrusion in this preliminary study.” ()

Spinal cord compressions are also possible with patients experiencing pain, rigidity and neurologic signs that may follow some distance along nerves to cause symptoms at some distance from the location of the retrolisthesis.

The salient feature of the disorder is the exuberant osteophytosis that occurs at posterior lumbar spinous processes. Osteophytes are coarse calcifications at the edges of bone that form due to repetitive stress and trauma. There is also atrophy and fatty replacement of paraspinal musculature, which can be detected by CT or MRI.

For children younger than eight weeks of age (and possibly in utero), a tethered cord may be observed using ultrasonography. Ultrasonography may still be useful through age 5 in limited circumstances.

MRI imaging appears to be the gold standard for diagnosing a tethered cord.

A tethered cord is often diagnosed as a "low conus." The conus medullaris (or lower termination of the spinal cord) normally terminates at or above the L1-2 disk space (where L1 is the first, or topmost lumbar vertebra). After about 3 months of age, a conus below the L1-2 disk space may indicate a tethered cord and termination below L3-4 is unmistakably tethered. "Cord tethering is often assumed when the conus is below the normal L2-3 level.

TCS, however, is a clinical diagnosis that should be based on "neurological and musculoskeletal signs and symptoms. Imaging features are in general obtained to support rather than make the diagnosis." Clinical evaluation may include a simple rectal examination and may also include invasive or non-invasive urological examination. "Bladder dysfunction occurs in ~40% of patients affected by tethered cord syndrome. ... [I]t may be the earliest sign of the syndrome."

A doctor will base his or her diagnosis on the symptoms the patient has and the results of tests, including:

- An X-ray

- Magnetic resonance imaging (MRI), which usually provides the most information

- Computed tomography (CT) scan

Handling may be painful and stressful because of their poor body movement and how the bones have grown. Due to the stress, handling should be kept to a minimum.

A reptile with spinal osteoarthropathy does not require a large vivarium. Like all vivaria it needs to be heated according to the particular reptile's needs, with a dark hiding area (e.g. a log or dark box), normal substrate and clean water for the reptile to access. It is advisable not to have anything too high for them to climb because the reptile's ability to hold onto branches (for example) is restricted; floor space is more important. It is best not to keep them with a tank-mate (especially a healthy one), since bullying may occur.

Myelopathy is primarily diagnosed by clinical exam findings. Because the term "myelopathy" describes a clinical syndrome that can be caused by many pathologies the differential diagnosis of myelopathy is extensive. In some cases the onset of myelopathy is rapid, in others, such as CSM, the course may be insidious with symptoms developing slowly over a period of months. As a consequence, the diagnosis of CSM is often delayed. As the disease is thought to be progressive, this may impact negatively on outcome.

Once the clinical diagnosis "myelopathy" has been established, the underlying cause needs to be investigated. Most commonly this involves the use of medical imaging techniques. The best way of visualising the spinal cord is Magnetic Resonance Imaging (MRI). Apart from T1 and T2 MRI images, which are commonly used for routine diagnosis, more recently the use quantitative MRI signals is being investigated. Further imaging modalities used for evaluating myelopathy include plain X-rays for detecting arthritic changes of the bones, and Computer Tomography, which is often used for pre-operative planning of surgical interventions for cervical spondylotic myelopathy. Angiography is used to examine blood vessels in suspected cases of vascular myelopathy.

The presence and severity of myelopathy can also be evaluated by means of Transcranial Magnetic Stimulation (TMS), a neurophysiological method that allows the measurement of the time required for a neural impulse to cross the pyramidal tracts, starting from the cerebral cortex and ending at the anterior horn cells of the cervical, thoracic or lumbar spinal cord. This measurement is called "Central Conduction Time" ("CCT"). TMS can aid physicians to:

- determine whether myelopathy exists

- identify the level of the spinal cord where myelopathy is located. This is especially useful in cases where more than two lesions may be responsible for the clinical symptoms and signs, such as in patients with two or more cervical disc hernias

- follow-up the progression of myelopathy in time, for example before and after cervical spine surgery

TMS can also help in the differential diagnosis of different causes of pyramidal tract damage.
