Scheuermann's disease

Scheuermann's disease is considered to be a form of juvenile osteochondrosis of the spine. It is found mostly in teenagers and presents a significantly worse deformity than postural kyphosis. Patients suffering with Scheuermann’s kyphosis cannot consciously correct their posture. The apex of their curve, located in the thoracic vertebrae, is quite rigid.^{[citation needed]}

Scheuermann's disease is notorious for causing lower and mid-level back and neck pain, which can be severe and disabling. The sufferer may feel pain at the apex of the curve, which is aggravated by physical activity and by periods of standing or sitting; this can have a significantly detrimental effect to their lives as their level of activity is curbed by their disability. The sufferer may feel isolated or uneasy amongst their peers if they are children, depending on the level of deformity.^{[citation needed]}

In addition to the pain associated with Scheuermann's disease, many sufferers of the disorder have loss of vertebral height, and depending on where the apex of the curve is, may have a visual 'hunchback' or 'roundback'. It has been reported that curves in the lower thoracic region cause more pain, whereas curves in the upper region present a more visual deformity. Nevertheless, it is typically pain or cosmetic reasons that prompt sufferers to seek help for their condition. In studies, kyphosis is better characterized for the thoracic spine than for the lumbar spine.^[6][7]

The seventh and tenth thoracic vertebrae are most commonly affected. It causes backache and spinal curvature. In very serious cases it may cause internal problems and spinal cord damage, but these cases are extremely rare. The curvature of the back decreases height, thus putting pressure on internal organs, wearing them out more quickly than the natural aging process; surgical procedures are almost always recommended in this case.^{[citation needed]}

Pain: Scheuermann’s patients had a higher risk for back pain and disabilities during activities of daily living than controls. However, the degree of thoracic kyphosis among Scheuermann’s patients was not related to back pain, quality of life, or general health.^[8]

Associated conditions

Many with Scheuermann's disease often have an excessive

Patients with Scheurmann's disease are prone to having a lower than average bone density. They are hence at a statistical greater long term risk for osteopenia and osteoporosis, the reason for this is unknown.^[1]

Causes

The cause is not currently known, and the condition appears to be multifactorial.

Diagnosis is typically by medical imaging. The degree of kyphosis can be measured by

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.^[citation needed]

While there is no explanation for what causes Scheuermann's disease, there are ways to treat it. For less extreme cases,

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.^[11] The method has been shown to reduce pain and decrease kyphotic angle significantly during an inpatient treatment program.^[12][13]

Bracing can be utilized to help prevent progression and in some cases reduce the hyperkyphosis Cobb angle. Conservative treatment of Scheuermann's hyperkyphosis in international literature is generally regarded as an effective treatment approach. Physiotherapy and bracing are the first-line treatments for this condition.^[14]

Braces such as the Scolibrace (kyphobrace) and Kyphologic brace systems have been shown to be effective in the treatment of Scheuermann's ^[14]

Surgery

Scheuermann's disease can be successfully corrected with surgical procedures, almost all of which include spinal fusion and hardware instrumentation, i.e., rods, pedicle screws, etc. While many patients are typically interested in getting surgery for their correction, it is important to realize the surgery aims to reduce pain, and not cosmetic defect. As always, surgical intervention should be used as a last resort once conservative treatment fails or the patient's health is in imminent danger as any surgical procedure is not without risk. However, the chances of complication are relatively low, and the surgeries are often successful.^{[citation needed]}

There are two primary surgical techniques to correct kyphosis: posterior-only fusion and anterior/posterior fusion. While debate lingers over which surgical approach is optimal, several studies published since 2018 suggest treatment trends are favoring posterior-only fusion.^[15][16][17]

The classic surgical procedure entails entering two titanium rods, each roughly 1.5 feet (0.46 m) long (depending on the size of the kyphosis) into the back on either side of the spine. Eight titanium screws and hardware are drilled through the bone to secure the rods onto either side of the spine. On the internal-facing side of the spine, ligaments (which can be too short, pulling the spine into its abnormal shape) must be surgically cut or released, not only stopping part of the cause of the kyphosis, but also allowing the titanium rods to pull the spine into a more natural position. The damaged discs between the troubled vertebrae (wedged vertebrae) are normally removed and replaced with bone grafting from the hip or other parts of the vertebrae, which once healed or "fused" will solidify. The titanium instrumentation holds everything in place during healing. The patient can expect to remain in hospital for minimum of a week, and possibly longer. They may then be required to wear a brace for several months more to ensure the spine heals appropriately. The titanium instrumentation may stay in the body permanently, or be removed years later. Patients who have undergone such surgery may need physical therapy to manage pain and mobility. Recovery can be prolonged: typically patients are not allowed to lift anything above 5–10 pounds (2.3–4.5 kg) for 6 months to 1 year, and many are out of work for at least six months. However, once the fusion is solidified, most patients can return to their usual lifestyle within 1–2 years.^{[citation needed]}

Prognosis

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.^[18][19] Taking into account that some of the symptoms of the spinal deformity cannot be changed by surgical intervention, surgery remains a cosmetic indication,^[18][20] though the cosmetic effects of surgery are not necessarily stable.^[18]
