However, deformity in either type has the potential for severe progression because most deformity starts while the patients are skeletally immature. Curve progression is especially rapid once the individual becomes non-ambulant (averaging 10° in Cobb angle/year) and usually curves extend to involve most of the thoracic and lumbar spine. A severe scoliosis compromises respiratory function and makes sitting more difficult. However, in order for that to happen, the child must be relatively thin (at least not terribly obese) so that the brace actually fits well. Thoracic Insufficiency Syndrome (TIS) is commonly used to describe the potential combined spine and lung problems in EOS. Further information can be found here. Further information can be found, The Scoliosis Society Past Present and Future, Spinal Interface Training Group (STIG) Pilot. Sometimes the shape changes can become a big concern. Whether stapling will prove to be a permanent and final procedure or whether for a given patient treatment will need to be finished off by converting the stapled spine to a spinal fusion will need to be determined on an individual basis.16, Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window), Click to share on Google+ (Opens in new window), Osteotomies and Vertebral Column Resections for Complex Spinal Deformities, Bracing and Nonoperative Treatment of Spinal Deformity, Anterior/Posterior (AP) Surgery for Spinal Deformity. Figure 14–1 This teenage girl had polio with the extensor hallucis longus on one foot as the only functioning lower extremity muscle. She developed a severe spinal deformity with 90 degrees of pelvic obliquity: (A) anterior/posterior (AP) and (B) bender thoracolumbar (TL) radio-graphs. Surgery in a growing child’s spine aims to reduce the risk of the curve worsening at the same time as trying to ensure the spine overall still grows and lengthens with time. As people with neuromuscular conditions often have other illnesses as well as their scoliosis, your surgeon will have to make choices with you about the appropriateness of surgery balanced with all the potential risks. The scoliosis then progresses with an acute deterioration during the growth spurt somewhere between the ages of 13 and 15 years, such that it becomes difficult or impossible to sit unaided. If the spine results in a lot of tilting of the trunk, it can affect function in a wheelchair and the ability to sit up straight and look ahead to interact with the environment. The severity of the abnormalities can vary between people and can change with time. A study in bone and joint surgery in 1971 followed that idiopathic scoliosis patients who had not received treatment for some years are at risk of decreasing their life expectancy by up to 14 years. Some syndromes have associated spinal deformities, which are particularly “malignant” in their severity and progression as well as their “refractoriness” to even surgical treatment (e.g., familial dysautonomia). The literature on this topic is very extensive. )5,9,10 may influence how the deformity is handled. The many causes of scoliosis include neuromuscular problems and inherited diseases or conditions caused by the environment. Common orthopaedic manifestations in SMA include scoliosis… Therefore, young children are often offered brace treatment until the spine has a chance to grow. 14–6). Though this technique does involve a spinal fusion, its effect on trunk height is less than would occur with a long posterior fusion because many fewer vertebrae are involved in the fusion segment15(Figs. Neuromuscular scoliosis is a direct result of a disease process or injury that has caused the spinal muscles to be deficient in supporting and stabilizing the vertebral column. The neurologic condition may be the patient’s primary diagnosis or may be part of a larger syndrome. This means an operation through a long scar on the back to put rods and screws into the bones of the spine and straighten the spine. Muscular dystrophy refers to a group of genetic muscle-wasting disorders.

Neuromuscular= involving the muscles and the nervous system (the brain, spine, and nerves) Scoliosis=a side-to-side curvature of the spine Scoliosis is a side-to-side curvature of the spine. In fact, the goals of surgical treatment are the following: correction of the curve in the coronal plane, normalization of sagittal alignment, leveling of the pelvis, and the achievement of a solid fusion (if in fact the surgical treatment being performed is a definitive fusion)1–3(Fig. Also, treatment of the underlying neurologic condition may actually have a profound effect on behavior and natural history of the spinal deformity; examples of this would be decompression of a Chiari malformation or the treatment of Duchenne’s muscular dystrophy with steroids. Spinal muscular atrophy (SMA) is a progressive neuromuscular condition characterized by hypotonia. parents and caretakers report excellent improvement in the child's quality of life after deformity correction; Increased risk of wound complications with: Poor nutritional status (serum albumin <3.5 g/dL) ... - Neuromuscular Scoliosis B 11/22/2020 26 . How Dr. Lowenstein Can Help. The severity of the underlying muscle abnormality, patient age (e.g., skeletal maturation status), general health, and the natural history of the underlying diagnosis all affect the deformity behavior. ... (10.8 years) but longer quality-adjusted life expectancy (4.84 QALYs) than nonoperative management (11.2 years; 3.21 QALYs). Traditionally definitive treatment means a long posterior spinal fusion to the pelvis (with possibly an anterior supplemental fusion) and posterior instrumentation. Compared with idiopathic scoliosis, neuromuscular scoliosis is much more likely to produce curves that progress, and continue progressing into adulthood. Neuromuscular Scoliosis. Surgery may also be advised if function is affected. The etiology of neuromuscular deformity is primarily that of muscular weakness and/or imbalance and control that affects trunk alignment. The developmental type of neuromuscular scoliosis would be associated with conditions that are recognized at birth or soon thereafter, and examples of such conditions would be cellular abnormalities, inherited myopathies, myelomeningocele, and cerebral palsy. Neuromuscular curves frequently present to the spine surgeon only after they have progressed to large magnitude. After all of this, the doctors may want you to go for further tests such as an MRI scan. This does stiffen as well as straighten the spine. Neuromuscular scoliosis is a sideways curvature of the spine caused by poor muscle control, neurological problems and other issues. The most common operation, posterior spinal fusion, is well established, well studied and performed widely. Even in those diseases with a fairly limited life expectancy, curve progression may occur early, and to improve the quality of life, early treatment may be necessary. Life expectancy for children with cerebral palsy and mental retardation: Implications for life care planning. The X - rays also show if there are causes for the scoliosis. We analyzed data from 84 patients with scoliosis with different neuromuscular disorders. Figure 14–1 This teenage girl had polio with the extensor hallucis longus on one foot as the only functioning lower extremity muscle. Log In or Register to continue There are some new techniques that fall into the category of “fusionless” spinal correction, and these would include such things as “growing rods,” vertebral stapling, and VEPTR (vertical expandable prosthetic titanium rib). A two-stage reconstruction was done involving a two-level vertebrectomy, anterior spinal fusion (ASF), posterior spinal fusion (PSF), and instrumentation to the pelvis with excellent correction: (C) AP and (D) lateral post-op radiographs. Additionally, these references have extensive bibliographies that provide the reader with an ample opportunity to peruse the many additional articles that address and expand on the comments in this chapter. When untreated, severe EOS may be associated with an increased risk of early death due to heart and lung disease. Neuromuscular scoliosis is the name given to the type of scoliosis that happens in people with problems with their nervous systems (brain, spinal cord or nerves) or muscles. In certain situations, only a short anterior spinal fusion with instrumentation may be indicated, especially in patients who are less involved neurologically, are walkers, and who have lumbar or thoracolumbar curves. If standing or bending is not possible, the doctors will do the examination in the wheelchair and then on the couch in the clinic. ♦ Nonoperative Treatment There is no need to avoid sport or exercise when you have neuromuscular scoliosis. Though most authors who have written about neuro-muscular spinal deformity suggest that treated patients benefit physically, functionally, and emotionally (and so do their caregivers)12,13 at least one article refutes this notion.14. Life expectancy in pediatric patients with cerebral palsy and neuromuscular scoliosis who underwent spinal fusion Article in Developmental Medicine & Child Neurology 45(10):677 - … Figure 14–5 This nonambulatory teenager with cerebral palsy developed a significant deformity [(A) AP and (B) lateral pre-op radiographs] associated with difficulty sitting (C). A same-day ASF and PSF. They are usually rigid braces and need to be worn 23 hours a day. Therefore, there is clear evidence of how neuromuscular deformities affect the patient functionally. A few of the more common conditions associated with NMS include muscular dystrophy, cerebral palsy, … However, today there are alternatives to this approach. Neuromuscular scoliosis usually develops early in life and can progress rapidly through growth and in adulthood. Sometimes, the screws and rods are attached from the very top of the spine (where the neck joins the trunk) to the pelvis bone. Depending on the underlying NMD, the prevalence of scoliosis is also different. Though most authors who have written about neuro-muscular spinal deformity suggest that treated patients benefit physically, functionally, and emotionally (and so do their caregivers)12,13 at least one article refutes this notion.14 Compared with other forms of scoliosis, neuromuscular scoliosis is more likely to continue increasing in size over time. Other types are affected not only by the muscular weakness but also abnormalities of the vertebrae (e.g., myelomeningocele) (Fig. | Your Spine Surgeon will talk to you about the risks and benefits of this type of an operation. (Curve progression and trunk imbalances are more severe in patients who are not able to walk). If it remains roughly the same each time you are seen then they will continue to monitor you until you are fully grown. The Spine Surgeon will send your child for X - rays. If the plan is to monitor your scoliosis, you will be asked to return in a few months (often 6 months) for another examination and X - ray. Health and Economic Outcomes of Posterior Spinal Fusion for Children With Neuromuscular Scoliosis. However, in order for that to happen, the child must be relatively thin (at least not terribly obese) so that the brace actually fits well. When braces are used, they should only be used when the patients are up and about, and not be worn at nighttime. Even in those diseases with a fairly limited life expectancy, curve progression may occur early, and to improve the quality of life, early treatment may be necessary. Scoliosis in the presence of a neuromuscular disorder (NMD) behaves entirely differently from the more predictable idiopathic scoliosis. Katz RT (2003). Excellent correction and balance were achieved: (C) AP and (D) lateral post-op radiographs. Either you, your child or someone else may notice that there are changes in the shape of the spine or that they are sitting or standing as straight as before. 14–5). Neuromuscular curves frequently present to the spine surgeon only after they have progressed to large magnitude. In the lumbar spine we detected an improvement of 27.5% (SD ± 32.9), in the thoracic spine 25.3% (SD ± 38.0). Revision of the spinal surgery resulted in normalization of spinal alignment and a solid fusion: (C) AP and (D) lateral post-op radiographs. Prognosis will also depend on any underlying disorders or comorbidities. Surgical treatment of the initial injury was performed but failed: (A) AP and (B) lateral radiographs. Traditionally definitive treatment means a long posterior spinal fusion to the pelvis (with possibly an anterior supplemental fusion) and posterior instrumentation. 14–4). Although large idiopathic curves in adolescence are generally not painful and do not interfere with activities of daily living, severe neuromuscular curves frequently cause impaired posture and discomfort that interfere with basic functions such as sitting (Fig. ALL Rights Reserved. This chapter will summarize the collective and traditional wisdom about neuromuscular spine deformity in general and address a few specific conditions to illustrate the concepts and difficulties in reaching the treatment goals of this condition. “Successful bracing” is continued until age 10 or 11, at which time definitive fusion can be performed without as much trunk shortening as would have occurred with fusion at an earlier age. Patients who have suffered a spinal cord injury secondary to spinal fracture and/or dislocation frequently have had surgical treatment for it. Figure 14–4 This older teenage girl with Rett syndrome has a severe kyphosis as her main deformity. 134 males)with spasticity and neuromuscular scoliosis who underwent spinal fusion (mean age at surgery 13 years 11 months, SD 3 years 4 months), and to identify exposure variables that could significantly predict survival times. Spinal Interface Training Group (STIG) PilotJune 17, 2019, MAGEC Rods - BSS Statement - 29 Nov 2018November 29, 2018, 2015 © BSS. Neuromuscular Scoliosis Further information can be found here. Patients who have suffered a spinal cord injury secondary to spinal fracture and/or dislocation frequently have had surgical treatment for it. Increasing disability with age causes difficulty walking that leads to becoming wheelchair bound at the age of 8 to 10 years. The literature on this topic is very extensive. Sometimes the head is not level or the pelvis is not level. Unfortunately there is no strong evidence that exercise alone stops a scoliosis progressing or improves it. Scoliosis-related factors like accumulated stress could have an effect on life expectancy. Contraindications to bracing are stiff curves with pelvic obliquity, very obese patients whom the brace does not fit properly, and those with an unreliable family situation in which compliance would be a problem.1–3. Patients with scoliosis should be informed as to the uncertainty of benefits and potential risks of surgery for scoliosis. Methods: Patients from 2 multicenter registries who underwent … The etiology of neuromuscular deformity is primarily that of muscular weakness and/or imbalance and control that affects trunk alignment. She developed a severe spinal deformity with 90 degrees of pelvic obliquity: (A) anterior/posterior (AP) and (B) bender thoracolumbar (TL) radio-graphs. Under base-case assumptions, PSF costs $50 100 per QALY gained. Contraindications to bracing are stiff curves with pelvic obliquity, very obese patients whom the brace does not fit properly, and those with an unreliable family situation in which compliance would be a problem.1–3 Life expectancy in pediatric patients with cerebral palsy and neuromuscular scoliosis who underwent spinal fusion November 2003 Developmental Medicine & Child Neurology 45(10):677-82 Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window)Click to share on Google+ (Opens in new window) The commonest initial plan is to be monitored. PSF costs $75 400 per patient. Common conditions that can result in a neuromuscular scoliosis include: Muscular dystrophy (eg Duchenne’s muscular dystrophy). The British Scoliosis Society represents surgeons, healthcare workers and researchers interested in the nature of and treatment of scoliosis and complex spine disorders. 1. In his 15 plus years of chiropractic and 13 years of scoliosis-specific chiropractic care, Dr. Alex has seen many patients with neuromuscular scoliosis. The doctors will talk that through with you.
