Patients with symptomatic isthmic anterolisthesis are initially offered conservative treatment consisting of activity modification, pharmacological intervention, and a physical therapy consultation.
- Physical therapy can evaluate and address postural and compensatory movement abnormalities.
- Anti-inflammatory medications (NSAIDS) in combination with paracetamol (Tylenol) can be tried initially. If a severe radicular component is present, a short course of oral steroids such as Prednisone or Methylprednisolone can be considered. Epidural steroid injections, either interlaminal or transforaminal, performed under fluoroscopic guidance can help with severe radicular (leg) pain. Lumbosacral orthoses may be of benefit for some patients but should be used on a temporary basis to prevent spinal muscle atrophy and loss of proprioception.
Body braces showed benefit in a randomised controlled trial.
The Milwaukee brace is one particular body brace that is often used to treat kyphosis in the US. Modern CAD/CAM braces are used in Europe to treat different types of kyphosis. These are much easier to wear and have better in-brace corrections than reported for the Milwaukee brace. Since there are different curve patterns (thoracic, thoracolumbar and lumbar), different types of brace are in use, with different advantages and disadvantages.
Degenerative anterolisthesis with spinal stenosis is one of the most common indications for spine surgery (typically a laminectomy) among older adults. Both minimally invasive and open surgical techniques are used to treat anterolisthesis.
In Germany, a standard treatment for both Scheuermann's disease and lumbar kyphosis is the Schroth method, a system of physical therapy for scoliosis and related spinal deformities.
It involves lying supine, placing a pillow under the scapular region and posteriorly stretching the cervical spine.
Scheuermann's disease is self-limiting after growth is complete, meaning that it generally runs its course and never presents further complication. Typically, however, once the patient is fully grown, the bones will maintain the deformity. For this reason, there are many treatment methods and options available that aim to correct the kyphosis while the spine is still growing, and especially aim to prevent it from worsening.
While there is no explanation for what causes Scheuermann's Disease, there are ways to treat it. For decades there has been a lot of controversy surrounding treatment options. For less extreme cases, manual medicine, physical therapy and/or back braces can help reverse or stop the kyphosis before it does become severe. Because the disease is often benign, and because back surgery includes many risks, surgery is usually considered a last resort for patients. In severe or extreme cases, patients may be treated through an extensive surgical procedure in an effort to prevent the disease from worsening or harming the body.
In Germany, a standard treatment for both Scheuermann's disease and lumbar kyphosis is the Schroth method, a system of specialized physical therapy for scoliosis and related spinal deformities. The method has been shown to reduce pain and decrease kyphotic angle significantly during an inpatient treatment program.
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.
There are links between human spinal morphology, bipedality, and scoliosis which suggest an evolutionary basis for the condition. Scoliosis has not been found in chimpanzees or gorillas. Thus, it has been hypothesized that scoliosis may actually be related to humans’ morphological differences from these apes. Other apes have a shorter and less mobile lower spine than humans. Some of the lumbar vertebrae in Pan are "captured", meaning that they are held fast between the ilium bones of the pelvis. Compared to humans, Old World monkeys have far larger erector spinae muscles, which are the muscles which hold the spine steady. These factors make the lumbar spine of most primates less flexible and far less likely to deviate than those of humans. While this may explicitly relate only to lumbar scolioses, it is possible that small imbalances in the lumbar spine could precipitate thoracic problems as well.
Scoliosis may be a byproduct of strong selection for bipedalism. For a bipedal stance, a highly mobile, elongated lower spine is very beneficial. For instance, the human spine takes on an S-shaped curve with lumbar lordosis, which allows for better balance and support of an upright trunk. Selection for bipedality was likely strong enough to justify the maintenance of such a disorder. Bipedality is hypothesized to have emerged for a variety of different reasons, many of which would have certainly conferred fitness advantages. It may increase viewing distance, which can be beneficial in hunting and foraging as well as protection from predators or other humans; it makes long distance travel more efficient for foraging or hunting; and it facilitates terrestrial feeding from grasses, trees, and bushes. Given the many benefits of bipedality which depends on a particularly formed spine, it is likely that selection for bipedalism played a large role in the development of the spine as we see it today, in spite of the potential for "scoliotic deviations". According to the fossil record, scoliosis may have been more prevalent among earlier hominids such as Australopithecus and Homo erectus, when bipedality was first emerging. Their fossils indicate that there may have been selection over time for a slight reduction in lumbar length to what we see today, favoring a spine that could efficiently support bipedality with a lower risk of scoliosis.
Spinal fusion for kyphosis and scoliosis is an extremely invasive surgery. The risk of complications is estimated to be about 10%. Possible complications may be inflammation of the soft tissue or deep inflammatory processes, breathing impairments, bleeding and nerve injuries, or infection. As early as five years after surgery around 5% require reoperation and long-term issues remain unclear. Taking into account that some of the symptoms of the spinal deformity cannot be changed by surgical intervention, surgery remains a cosmetic indication, though the cosmetic effects of surgery are not necessarily stable.
Gibbus deformity is a form of structural kyphosis typically found in the upper lumbar and lower thoracic vertebrae, where one or more adjacent vertebrae become wedged. Gibbus deformity most often develops in young children as a result of spinal tuberculosis and is the result of collapse of vertebral bodies. This can in turn lead to spinal cord compression causing paraplegia.
In addition to tuberculosis, other possible causes of gibbus deformity include pathological diseases, hereditary and congenital conditions, and physical trauma to the spine that results in injury. Gibbus deformity may result from the sail vertebrae associated with cretinism (the childhood form of hypothyroidism), mucopolysaccharidosis (MPS), and certain congenital syndromes, including achondroplasia. Because most children with MPS I (Hurler Syndrome) also exhibit symptoms of a gibbus deformity, the latter can possibly be used to identify the former.
Gibbus deformity is included in a subset of structural kyphosis that is distinguished by a higher-degree angle in the spinal curve that is specific to these forms of kyphosis. Other conditions within this subset include Pott’s disease and Scheuermann kyphosis, but gibbus deformity is marked by an especially sharp angle. Viewed from behind, the resulting hunchback is more easily seen when bending forward. A kyphosis of >70° can be an indication of the need for surgery and these surgeries can be necessary for children as young as two years old, with a reported average of 8 years of age.
The use of surgery to treat a Jefferson fracture is somewhat controversial. Non-surgical treatment varies depending on if the fracture is stable or unstable, defined by an intact or broken transverse ligament and degree of fracture of the anterior arch. An intact ligament requires the use of a soft or hard collar, while a ruptured ligament may require traction, a halo or surgery. The use of rigid halos can lead to intracranial infections and are often uncomfortable for individuals wearing them, and may be replaced with a more flexible alternative depending on the stability of the injured bones, but treatment of a stable injury with a halo collar can result in a full recovery. Surgical treatment of a Jefferson fracture involves fusion or fixation of the first three cervical vertebrae; fusion may occur immediately, or later during treatment in cases where non-surgical interventions are unsuccessful. A primary factor in deciding between surgical and non-surgical intervention is the degree of stability as well as the presence of damage to other cervical vertebrae.
Though a serious injury, the long-term consequences of a Jefferson's fracture are uncertain and may not impact longevity or abilities, even if untreated. Conservative treatment with an immobilization device can produce excellent long-term recovery.
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.
Treatment options vary from very conservative to aggressive. Conservative options include rest, observation, pain control, diet changes, use of a nasopharyngeal tube or oropharyngeal tube, and antibiotic therapy. More aggressive options include surgical repair of the hyoid bone and/or tracheotomy. Surgical treatment was used in 10.9% of cases in a 2012 meta-analysis.
Initial treatment in lumbar disc disease is one or two days of bedrest (although growing number of studies shows that it makes little difference) and pain relieving medications. In cases with ongoing pain despite conservative treatments, a surgical operation that will remove the compressing disc material, a microdiscectomy or discectomy may be recommended to treat a lumbar disc herniation.
A Cochrane review of low-intensity pulsed ultrasound to speed healing in newly broken bones found insufficient evidence to justify routine use. Other reviews have found tentative evidence of benefit. It may be an alternative to surgery for established nonunions.
Vitamin D supplements combined with additional calcium marginally reduces the risk of hip fractures and other types of fracture in older adults; however, vitamin D supplementation alone did not reduce the risk of fractures.
The cause of spondylolysis remains unknown, however many factors are thought to contribute to its development. The condition is present in up to 6% of the population, majority of which usually present asymptomatically. Research supports that there are hereditary and acquired risk factors that can make one more susceptible to the defect. The disorder is generally more prevalent in males compared to females, and tends to occur earlier in males due to their involvement in more strenuous activities at a younger age. In a young athlete, the spine is still growing which means there are many ossification centers, leaving points of weakness in the spine. This leaves young athletes at increased risk, particularly when involved in repetitive hyperextension and rotation across the lumbar spine. Spondylolysis is a common cause of low back pain in preadolescents and adolescent athletes, as it accounts for about 50% of all low back pain. It is believed that both repetitive trauma and an inherent genetic weakness can make an individual more susceptible to spondylolysis.
Over 2.5 million child abuse and neglect cases are reported every year, and thirty-five out of every hundred cases are physical abuse cases. Bone fractures are sometimes part of the physical abuse of children; knowing the symptoms of bone fractures in physical abuse and recognizing the actual risks in physical abuse will help forward the prevention of future abuse and injuries. Astoundingly, these abuse fractures, if not dealt with correctly, have a potential to lead to the death of the child.
Fracture patterns in abuse fractures that are very common with abuse are fractures in the growing part of a long bone (between the shaft and the separated part of the bone), fractures of the humeral shaft (long bone between the shoulder and elbow), ribs, scapula, outer end of the clavicle, and vertebra. Multiple fractures of varying age, bilateral fractures, and complex skull fractures are also linked to abuse. Fractures of varying ages occur in about thirteen percent of all cases.
The cost of scoliosis involves both monetary losses and lifestyle limitations that increase with severity. Respiratory deficiencies may also arise from thoracic deformities and cause abnormal breathing. This directly affects exercise and work capacity, decreasing the overall quality of life.
In the health care system of the United States, the average hospital cost for cases involving surgical procedures was $30,000 to $60,000 per patient in 2010. As of 2006, the cost of bracing has been published as up to $5,000 during rapid growth periods, when braces must be consistently replaced across multiple follow-ups.
A retrolisthesis is a posterior displacement of one vertebral body with respect to the subjacent vertebra to a degree less than a luxation (dislocation). Clinically speaking, retrolisthesis is the opposite of spondylolisthesis (anterior displacement of one vertebral body on the subjacent vertebral body), and is also called retrospondylolisthesis. Retrolistheses are most easily diagnosed on lateral x-ray views of the spine. Views, where care has been taken to expose for a true lateral view without any rotation, offer the best diagnostic quality.
Retrolistheses are found most prominently in the cervical spine and lumbar region but can also be seen in the thoracic area.
Children in general are at greater risk because of their high activity levels. Children that have risk-prone behaviors are at even greater risk.
In children, whose bones are still developing, there are risks of either a growth plate injury or a greenstick fracture.
- A greenstick fracture occurs due to mechanical failure on the tension side. That is, since the bone is not so brittle as it would be in an adult, it does not completely fracture, but rather exhibits bowing without complete disruption of the bone's cortex in the surface opposite the applied force.
- Growth plate injuries, as in Salter-Harris fractures, require careful treatment and accurate reduction to make sure that the bone continues to grow normally.
- Plastic deformation of the bone, in which the bone permanently bends, but does not break, also is possible in children. These injuries may require an osteotomy (bone cut) to realign the bone if it is fixed and cannot be realigned by closed methods.
- Certain fractures mainly occur in children, including fracture of the clavicle and supracondylar fracture of the humerus.
Vasodilators improve the blood flow into the vessels of the hoof. Examples include isoxsuprine (currently unavailable in the UK) and pentoxifylline.
Anticoagulants can also improve blood flow. The use of warfarin has been proposed, but the extensive monitoring required makes it unsuitable in most cases.
Anti-inflammatory drugs are used to treat the pain, and can help the lameness resolve sometimes if shoeing and training changes are made. Include Nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, and other joint medications. The use of intramuscular glycosaminoglycans has been shown to decrease pain in horses with navicular disease, but this effect wanes after discontinuation of therapy. Oral glycosaminoglycans may have a similar effect.
Bisphosphonates can be useful in cases where bone remodeling is causing pain.
Gallium nitrate (GaN) has been hypothesized as a possible treatment for navicular disease, but its benefits have not been confirmed by formal clinical studies. One pilot study examined horses given gallium nitrate in their feed rations. While it was absorbed slowly, it did stay in the animals' system, providing a baseline dosage for future studies.
Current surgical procedures used to treat spondylosis aim to alleviate the signs and symptoms of the disease by decreasing pressure in the spinal canal (decompression surgery) and/or by controlling spine movement (fusion surgery).
Decompression surgery: The vertebral column can be operated on from both an anterior and posterior approach. The approach varies depending on the site and cause of root compression. Commonly, osteophytes and portions of intervertebral disc are removed.
Fusion surgery: Performed when there is evidence of spinal instability or mal-alignment. Use of instrumentation (such as pedicle screws) in fusion surgeries varies across studies.
A cervical rib in humans is an extra rib which arises from the seventh cervical vertebra. Sometimes known as "neck ribs", their presence is a congenital abnormality located above the normal first rib. A cervical rib is estimated to occur in 0.2% (1 in 500 people) to 0.5% of the population. People may have a cervical rib on the right, left or both sides.
Most cases of cervical ribs are not clinically relevant and do not have symptoms; cervical ribs are generally discovered incidentally. However, they vary widely in size and shape, and in rare cases, they may cause problems such as contributing to thoracic outlet syndrome, because of pressure on the nerves that may be caused by the presence of the rib.
A cervical rib represents a persistent ossification of the C7 lateral costal element. During early development, this ossified costal element typically becomes re-absorbed. Failure of this process results in a variably elongated transverse process or complete rib that can be anteriorly fused with the T1 first rib below.
On imaging, cervical ribs can be distinguished because their transverse processes are directed inferolaterally, whereas those of the adjacent thoracic spine are directed anterolaterally.
Sports involving repetitive or forceful hyperextension of the spine, especially when combined with rotation are the main mechanism of injury for spondylolysis. The stress fracture of the pars interarticularis occurs on the side opposite to activity. For instance, for a right-handed player, the fracture occurs on the left side of the vertebrae.
Spondylolysis has a higher occurrence in the following activities:
- Baseball
- Tennis
- Diving
- Cheerleading
- Gymnastics
- Football
- Soccer
- Wrestling
- Weightlifting
- Roller Derby
- Cricket
- Pole Vault
- Rugby
- Volleyball
- Gym
- Ultimate Frisbee (especially during impact from laying out)
Although this condition can be caused by repetitive trauma to the lumbar spine in strenuous sports, other risk factors can also predispose individuals to spondylolsis. Males are more commonly affected by spondylolysis than females. In one study looking at youth athletes, it was found that the mean age of individuals with spondylolisthesis was 20 years of age. Spondylolysis also runs in families suggesting a hereditary component such as a predisposition to weaker vertebrae.
The hyoid bone fracture is a very rare fracture of the hyoid bone, accounting for 0.002% of all fractures in humans. It is commonly associated with strangulation and rarely occurs in isolation. The fracture may be associated with gunshot injury, car accidents or induced vomiting. In 50% of strangulations and 27% of hangings, hyoid fractures occur.
