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.

DISH is diagnosed by findings on x-ray studies. Radiographs of the spine will show abnormal bone formation (ossification) along the anterior spinal ligament. The disc spaces, facet and sacroiliac joints remain unaffected. Diagnosis requires confluent ossification of at least four contiguous vertebral bodies. Classically, advanced disease may have "melted candle wax" appearance along the spine on radiographic studies. In some cases, DISH may be manifested as ossification of enthesis in other parts of the skeleton.

The calcification and ossification is most common on the right side of the spine. In people with dextrocardia and situs inversus this calcification occurs on the left side, which confirms the role of the descending thoracic aorta in preventing the physical manifestations of DISH on one side of the spine.

The pectus carinatum can be easily diagnosed by certain tests like "CT scan(2D and 3D)". It may be then found out that the rib cage is in normal structure . If there is more than average growth of sternum than pectus carinatum protrudes .Also it is of two types , as pectus carinatum is symmetrical or unsymmetrical . On the basis of that further treatment is given to the patient.

Different features of the dysostosis are significant. Radiological imaging helps confirm the diagnosis. During gestation (pregnancy), clavicular size can be calculated using available nomograms. Wormian bones can sometimes be observed in the skull.

Diagnosis of CCD spectrum disorder is established in an individual with typical clinical and radiographic findings and/or by the identification of a heterozygous pathogenic variant in RUNX2 (CBFA1).

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.

Schmorl's nodes can be detected with x-ray, although they can be imaged better by CT or MRI. They are considered to be vertical disc herniations through the cartilaginous vertebral body endplates. Schmorl's nodes can sometimes be seen radiographically, however they are more often seen on MRI, even when not visible on plain film x-ray. They may or may not be symptomatic, and their etiological significance for back pain is controversial. In a study in Spine by Hamanishi, et al., Schmorl's nodes were observed on MRI in 19% of 400 patients with back pain, and in only 9% of an asymptomatic control group. The authors concluded that Schmorl's nodes are areas of "vertical disc herniation" through areas of weakness in the endplate.

Presence at birth is extremely rare and associated with other congenital anomalies such as proximal femoral focal deficiency, fibular hemimelia or anomalies in other part of the body such as cleidocranial dyastosis. The femoral deformity is present in the subtrochantric area where the bone is bent. The cortices are thickened and may be associated with overlying skin dimples. External rotation of the femur with valgus deformity of knee may be noted. This condition does not resolve and requires surgical management. Surgical management includes valgus osteotomy to improve hip biomechanics and length and rotational osteotomy to correct retroversion and lengthening.

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.

Pectus excavatum requires no corrective procedures in mild cases. Treatment of severe cases can involve either invasive or non-invasive techniques or a combination of both. Before an operation proceeds several tests are usually to be performed. These include, but are not limited to, a CT scan, pulmonary function tests, and cardiology exams (such as auscultation and ECGs). After a CT scan is taken, the Haller index is measured. The patient's Haller is calculated by obtaining the ratio of the transverse diameter (the horizontal distance of the inside of the ribcage) and the anteroposterior diameter (the shortest distance between the vertebrae and sternum). A Haller Index of greater than 3.25 is generally considered severe, while normal chest has an index of 2.5. The cardiopulmonary tests are used to determine the lung capacity and to check for heart murmurs.

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

Pectus excavatum is initially suspected from visual examination of the anterior chest. Auscultation of the chest can reveal displaced heart beat and valve prolapse. There can be a heart murmur occurring during systole caused by proximity between the sternum and the pulmonary artery.

Lung sounds are usually clear yet diminished due to decreased base lung capacity.

Many scales have been developed to determine the degree of deformity in the chest wall. Most of these are variants on the distance between the sternum and the spine. One such index is the "Backer ratio" which grades severity of deformity based on the ratio between the diameter of the vertebral body nearest to xiphosternal junction and the distance between the xiphosternal junction and the nearest vertebral body. More recently the "Haller index" has been used based on CT scan measurements. An index over 3.25 is often defined as severe. The Haller index is the ratio between the horizontal distance of the inside of the ribcage and the shortest distance between the vertebrae and sternum.

Chest x-rays are also useful in the diagnosis. The chest x-ray in pectus excavatum can show an opacity in the right lung area that can be mistaken for an infiltrate (such as that seen with pneumonia). Some studies also suggest that the Haller index can be calculated based on chest x-ray as opposed to CT scanning in individuals who have no limitation in their function.

Pectus excavatum is differentiated from other disorders by a series of elimination of signs and symptoms. Pectus carinatum is excluded by the simple observation of a collapsing of the sternum rather than a protrusion. Kyphoscoliosis is excluded by diagnostic imaging of the spine, where in pectus excavatum the spine usually appears normal in structure.

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.

Conventional radiography is usually the initial assessment tool when a calcaneal fracture is suspected. Recommended x-ray views are (a) axial, (b) anteroposterior, (c) oblique and (d) views with dorsiflexion and internal rotation of the foot. However, conventional radiography is limited for visualization of calcaneal anatomy, especially at the subtalar joint. A CT scan is currently the imaging study of choice for evaluating calcaneal injury and has substituted conventional radiography in the classification of calcaneal fractures. Axial and coronal views are obtained for proper visualization of the calcaneus, subtalar, calcaneocuboid and talonavicular joints.

Manipulative physiotherapy, therapeutic exercises and chiropractic manipulative therapy shows beneficial results for decreasing pain and increasing spinal range of motion. As areas of the spine and tendons can become inflamed NSAIDs such as ibuprofen and Naproxen can be helpful in both relieving pain and inflammation associated with DISH. It is hoped that by minimizing inflammation in these areas, further calcification of tendons and ligaments of the spine leading to bony outgrowths (enthesophytes) will be prevented, although causative factors are still unknown.

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.

The use of orthotic bracing, pioneered by Sydney Haje as of 1977, is finding increasing acceptance as an alternative to surgery in select cases of pectus carinatum. In children, teenagers, and young adults who have pectus carinatum and are motivated to avoid surgery, the use of a customized chest-wall brace that applies direct pressure on the protruding area of the chest produces excellent outcomes. Willingness to wear the brace as required is essential for the success of this treatment approach. The brace works in much the same way as orthodontics (braces that correct the alignment of teeth). The brace consists of front and back compression plates that are anchored to aluminum bars. These bars are bound together by a tightening mechanism which varies from brace to brace. This device is easily hidden under clothing and must be worn from 14 to 24 hours a day. The wearing time varies with each brace manufacturer and the managing physicians protocol, which could be based on the severity of the carinatum malformation (mild moderate severe) and if it is symmetric or asymmetric.

Depending on the manufacturer and/or the patient's preference, the brace may be worn on the skin or it may be worn over a body 'sock' or sleeve called a Bracemate, specifically designed to be worn under braces. A physician or orthotist or brace manufacturer's representative can show how to check to see if the brace is in correct position on the chest.

Bracing is becoming more popular over surgery for pectus carinatum, mostly because it eliminates the risks that accompany surgery. The prescribing of bracing as a treatment for pectus carinatum has 'trickled down' from both paediatric and thoracic surgeons to the family physician and pediatricians again due to its lower risks and well-documented very high success results. The pectus carinatum guideline of 2012 of the American Pediatric Surgical Association has stated: "As reconstructive therapy for the compliant pectus [carinatum] malformation, nonoperative compressive orthotic bracing is usually an appropriate first line of therapy as it does not preclude the operative option. For appropriate candidates, orthotic bracing of chest wall malformations can reasonably be expected to prevent worsening of the malformation and often results in a lasting correction of the malformation. Orthotic bracing is often successful in prepubertal children whose chest wall is compliant. Expert opinion suggests that the noncompliant chest wall malformation or significant asymmetry of the pectus carinatum malformation caused by a concomitant excavatum-type malformation may not respond to orthotic bracing."

Regular supervision during the bracing period is required for optimal results. Adjustments may be needed to the brace as the child grows and the pectus improves.

Around 5 years of age, surgical correction may be necessary to prevent any worsening of the deformity. If the mother has dysplasia, caesarian delivery may be necessary. Craniofacial surgery may be necessary to correct skull defects. Coxa vara is treated by corrective femoral osteotomies. If there is brachial plexus irritation with pain and numbness, excision of the clavicular fragments can be performed to decompress it. In case of open fontanelle, appropriate headgear may be advised by the orthopedist for protection from injury.

The presence of a cervical rib can cause a form of thoracic outlet syndrome due to compression of the lower trunk of the brachial plexus or subclavian artery. These structures become encroached upon by the cervical rib and scalene muscles.

Compression of the brachial plexus may be identified by weakness of the muscles around the muscles in the hand, near the base of the thumb. Compression of the subclavian artery is often diagnosed by finding a positive Adson's sign on examination, where the radial pulse in the arm is lost during abduction and external rotation of the shoulder. A positive Adson's sign is non-specific for the presence of a cervical rib however, as many individuals without a cervical rib will have a positive test.

Evaluating soft-tissue involvement is the most important aspect of the clinical examination because of its association with patient outcome. Skin blisters may become infected if medical attention is delayed, which can lead to necrotizing fasciitis or osteomyelitis, causing permanent damage to muscle or bone. Ligament and tendon involvement should also be explored. Achilles tendon injury can be seen with posterior (Type C) fractures. Since calcaneal fractures are related to falls from height, other concomitant injuries should be evaluated. Vertebral compression fractures occur in approximately 10% of these patients. A trauma-focused clinical approach should be implemented; tibial, knee, femur, hip, and head injuries should be ruled out by means of history and physical exam.

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 U.S. Preventive Services Task Force (USPSTF) recommend that all women 65 years of age or older be screened by bone densitometry. Additionally they recommend screening women with increased risk factors that puts them at risk equivalent to a 65‑year‑old. There is insufficient evidence to make recommendations about the intervals for repeated screening and the appropriate age to stop screening. In men the harm versus benefit of screening for osteoporosis is unknown. Prescrire states that the need to test for osteoporosis in those who have not had a previous bone fracture is unclear. The International Society for Clinical Densitometry, however, suggest BMD testing for men 70 or older, or those who are indicated for risk equal to that of a 70‑year‑old. A number of tools exist to help determine who is reasonable to test.

Scoliosis is well established and even evaluated at an early age. It is typically quantified using the standardized Cobb angle method. This method consists of measuring the degree of deformity by the angle between two successive vertebrae. The Cobb method was accepted by the Scoliosis Research Society (SRS) in 1966. It serves as the standard method for quantification of scoliosis deformities. Sagittal plane posture aberrations such as cervical and lumbar lordosis and thoracic kyphosis have yet to be quantified due to considerable inter-individual variability in normal sagittal curvature. The Cobb method was also one of the first techniques used to quantify sagittal deformity. As a 2D measurement technique it has limitations and new techniques are being proposed for measurement of these curvatures. Most recently, 3D imaging techniques using computed tomography (CT) and magnetic resonance (MR) have been attempted. These techniques are promising but lack the reliability and validity necessary to be used as a reference for clinical purposes.

Posture assessment has also become quite popular in many practical environments like the personal training and sports conditioning settings. The need for reliable methods of posture assessment as a screening tool is warranted. Current available programs such as those through the National Posture Institute (NPI) and Posture Print are recommended for the practical setting but cost close to $1000 and are clearly a profiteering scam by individuals not at all concerned with human well-being.

Chronic deviations from neutral spine lead to improper posture, increased stress on the back and causes discomfort and damage. People who sit for long hours on the job are susceptible to a number of misalignments.

"Neutral spine" is ideally maintained while sitting, standing, and sleeping.

More common cause: primary defect in endochondral ossification of the medial part of the femoral neck.

Excessive interuterine pressure on the developing fetal hip.

vascular insult.

Faulty maturation of the cartilage and metaphyseal bone of the femoral neck.

Clinical feature: presents after the child has started walking but before six years of age. Usually associated with a painless hip due to mild abductor weakness and mild limb length discrepancy.

If there is a bilateral involvement the child might have a waddling gait or trendelenburg gait with an increased lumbar lordosis. The greater trochanter is usually prominent on palpation and is more proximal. Restricted abduction and internal rotation.

X-ray: decreased neck shaft angle, increased cervicofemoral angle, vertical physis, shortened femoral neck decrease in femoral anteversion. HE angle (hilgenriener epiphyseal angle- angle subtended between a horizontal line connecting the triradiate cartilage and the epiphysisn normal angle is <30 degrees.

Treatment:

HE angle of 45–60 degrees observation and periodic follow up.

Indication for surgery :HE angle more than 60 degrees, progressive deformity, neckshaft angle <90 degrees, development of trendelenburg gait

Surgery: subtrochantric valgus osteotomy with adequate internal rotation of distal fragment to correct anteversion

common complication is recurrence. If HE angle is reduced to 38 degrees less evidence of recurrence

post operative spica cast is used for a period of 6–8 weeks.

Coxa vara is also seen in Niemann–Pick disease.

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.

Congenital vertebral anomalies are a collection of malformations of the spine. Most around 85% are not clinically significant, but they can cause compression of the spinal cord by deforming the vertebral canal or causing instability. This condition occurs in the womb. Congenital vertebral anomalies include alterations of the shape and number of vertebrae.
