Patient advocacy groups have proved to be very useful in helping families cope with the illness and associated surgical care. Based on the current evidence, no significant conclusions can be drawn about the impact of intrathecal baclofen pumps on the progression or treatment of spinal deformity in patients with cerebral palsy. In very small or thin patients, the authors continue to prefer a Galveston rod construct for pelvic fixation. Get the facts on scoliosis types and symptoms. Figure 24–14 A and B, This severe 140-degree lumbar curve was upsetting wheelchair sitting balance in this spastic quadriplegic patient. The effect of bracing on pulmonary dysfunction seems to depend on the level of muscle spasticity. Copyright © 2003 Elsevier Ltd. All rights reserved. In nonambulatory patients with neuromuscular scoliosis, surgeons have relied on rods or screws inserted into the iliac wings by a cantilever method to level the pelvis. These x-rays keep track of changes until your child has finished growing. Preoperatively, patients may have compromised pulmonary function, limited cardiac capacity, poor bone stock, and high risk for aspiration, which put them in danger of intraoperative or postoperative complications. Improvement on the Galveston concept has been the focus of many clinical studies.69,72–74 The use of S1 screws alone was investigated, but bone quality is generally not substantial enough for successful use in patients with neuromuscular scoliosis. The use of a wheelchair affords these patients educational and social opportunities that enrich their lives. These results are contrary to other studies reported in the literature. The introduction of segmental spinal instrumentation by Luque49 in 1976 led to major advances in the biomechanical stability and correction of these very deformed spines (Fig. The benefit of scoliosis surgery in this population is a topic of much debate. However, there are treatments available for people who have neuromuscular scoliosis, including: Wheelchair modifications. FIGURE 24–10 Radiolucency around rod tip in ilium (windshield wiper effect) suggests lumbosacral pseudarthrosis, which may remain asymptomatic and resolve spontaneously. Olafsson and colleagues18 followed 90 patients with various neuromuscular conditions treated with a soft Boston orthosis for an average of 3 years after brace treatment. Survival into adulthood is now a realistic possibility for many patients who received optimal treatment.12 Although gene-based and cellular-based therapies are currently under development for the treatment of DMD, the efficacy of glucocorticoid steroids has been evaluated by several randomized controlled trials. Although many patients already have neurologic compromise, they are still at risk for further compromise because of intraoperative spinal column manipulation. Although less common since the advent of segmental instrumentation and decreased use of casting, this prolonged obstruction carries significant morbidity; identifying at-risk patients and maintaining a high index of suspicion when encountering protracted vomiting is essential. This clinical course emphasizes that fixation challenges are present in patients with neuromuscular deformity, particular hyperkyphosis. Modular seating systems can be configured for optimal support of an individual patient (Fig. Lonstein and Akbarnia29 reported that more than 50% of patients treated had functional improvement after surgery. "For these patients, we almost always use allografts [freeze-dried, irradiated donor bone] with excellent results," says Dr. Widm… Many patients with neuromuscular scoliosis are on long-term seizure therapy, which has some important operative ramifications. The objective of treatment in neuromuscular scoliosis is to maximise patient's function whilst preventing progression of the scoliosis. Rinsky LA. In 1942, Haas47 published one of the first references to surgical intervention in neuromuscular scoliosis: a case report describing muscle and fascial transfers to obtain complete and permanent correction in one patient. Physicians may wish to provide information regarding clinical trials or refer families to clinical trial websites (www.clinicaltrials.gov provides a current listing of open clinical trials). To stop the curve from getting worse and help you go back to doing the things you love, Medtronic developed surgical treatment options for scoliosis. With a molded wheelchair, the patient with neuromuscularscoli… Patients with spastic disorders generally do not tolerate rigid brace treatment, whereas patients with flaccid paresis are more apt to be compliant with brace treatment. The natural history for a given patient is largely determined by the specific underlying neuromuscular condition and the degree of involvement. Neuromuscular scoliosis: The spine may also curve due to specific abnormalities of the nervous or musculoskeletal system, such as cerebral palsy, Marfan syndrome, or neurofibromatosis. Neuromuscular scoliosis (NMS) is a type of scoliosis that occurs in individuals with conditions that affect the muscles and / or connective tissues that support the spine. Background: Patients with neuromuscular scoliosis (NMS) can pose treatment challenges related to medical comorbidities and altered spinopelvic anatomy. Dietary supplements Whether your child has idiopathic, neuromuscular or congenital scoliosis, the primary goal of any treatment is to stop the curve from getting worse. FIGURE 24–5 A and B, Wheelchair systems can provide sitting support for patients who are not good candidates for bracing. Spinal surgery is considered the primary treatment option for correcting severe scoliosis in neuromuscular disorders. Copyright © 2021 Elsevier B.V. or its licensors or contributors. Adolescent idiopathic scoliosis is the most common type of scoliosis and is usually diagnosed during puberty. When patients with neuromuscular scoliosis are instrumented because of the severe obliquity of the pelvis, intraoperative halo-femoral traction may also be beneficial. Some patients are capable of ambulation, although many lose their ability to walk early in life or never achieve ambulatory status at all. This can only be achieved by better education of referring physicians on the importance of timing of surgery. 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. The pediatric orthopedic surgeon addresses the curve by realigning the bone using rods and bone grafts to fuse areas of the spine and maintain the correction. Anterior release is necessary only in severe deformities. Regardless of severity, scoliosis pain is rare. Several studies have shown that anterior instrumentation alone provides acceptable correction without the need for posterior instrumentation in selected short flexible curves that do not include the pelvis or have less than 15 degrees of pelvic obliquity. Randomized placebo-controlled trials have been conducted investigating the efficacy of several medical treatments for SMA, including creatine, phenylbutyrate, gabapentin, and thyrotropin-releasing hormone.2–5 None of these compounds has proven to be an efficacious drug treatment for SMA.2. Many patients are malnourished secondary to a combination of reflux, low calorie intake, and high metabolic demand from frequent illness. It is important to avoid “locking in” a poor correction with anterior instrumentation in rigid curves. 24–1). FIGURE 24–9 A, Failure of proximal sublaminar wiring in this construct resulted in increased kyphosis and prominent hardware necessitating revision surgery 3 years after primary procedure. It is characterized by an abnormal lateral curvature of the spine and there are many different forms. Mild cases may not affect daily living. Askin and colleagues30 evaluated 20 patients with neuromuscular scoliosis preoperatively and 6, 12, and 24 months after corrective spinal surgery. What are the treatment options for neuromuscular scoliosis? Studies of patient outcomes with unit rod fixation have revealed excellent correction and maintenance of correction.54–56 Bulman and colleagues57 compared the unit rod with double Luque rods and reported superior correction of sagittal and coronal alignment and pelvic obliquity with the unit rod constructs. More powerful instrumentation systems have led to less postoperative decompensation and pseudarthrosis; however, there remains a considerable risk of curve progression, sometimes necessitating revision surgery.26–28. In skeletally immature patients with idiopathic scoliosis, anterior release and fusion reduces anterior overgrowth that results in crankshaft deformity; however, whether this principle can be applied in neuromuscular scoliosis is controversial. The benefit of scoliosis surgery in this population is a topic of much debate. Patients with DMD may have cardiomyopathy and arrhythmias. The curve severity guidelines are loosely based on, but less aggressive than, the guidelines used in idiopathic scoliosis. Mercado and colleagues. The rotation component start… In a study of 20 nonambulatory patients with neuromuscular scoliosis with halo-femoral traction and 20 matched patients without halo-femoral traction, Takeshita and colleagues78 found that halo-femoral traction provided significantly improved lumbar curve and pelvic obliquity correction at 2-year follow-up. These results have been supported by a meta-analysis by Gill and colleagues,46 which found that tranexamic acid and aminocaproic acid are effective in minimizing blood loss and transfusion in patients undergoing spine surgery. These abnormalities in the spine, costal-vertebral joints, and the rib cage produce a ‘convex’ and ‘concave’ hemithorax. Several pharmacologic agents have been under investigation for their efficacy in reducing blood loss during surgery. If a patient cannot be assessed with formal pulmonary function tests, other signs of ventilatory capacity must be used, including crying, laughing, and other vocalizations.38–40. If the curve remains rigid after an anterior release, the anterior instrumentation is skipped, and either an apical vertebrectomy is performed, or the correction is achieved after posterior osteotomies (Fig. In all other patients, brace wear was ineffectual in altering progression but did provide assistance in sitting. The dilemma faced by the surgeon is how to stop the progression of a curve without adversely a… Scoliosis is defined by the Cobb's angle of spine curvature in the coronal plane, and is often accompanied by vertebral rotation in the transverse plane and hypokyphosis in the sagittal plane. Common conditions that can result in a neuromuscular scoliosis include: Regardless of whether the precontoured unit rod or double Luque rods are used, segmental sublaminar wire instrumentation provides simple, inexpensive, and fairly powerful correction of coronal plane deformity. Botulinum toxin has gained a growing acceptance as a treatment of upper and lower limb spasticity. By continuing you agree to the use of cookies. The sagittal profile is another important consideration because lordotic and kyphotic deformities can also impair sitting balance and pulmonary capacity (Fig. Intrathecal baclofen has been shown to reduce the need for orthopaedic lower extremity procedures and the rate of postoperative complications associated with these procedures.8 Concerns have been raised, however, regarding its impact on the progression of scoliosis in patients with spastic quadriplegia. Certain types of scoliosis have a greater chance of getting worse, so the type of scoliosis also helps to determine the proper treatment. A multidisciplinary approach is needed in the treatment of neuromuscular scoliosis. This may be achieved nonsurgically or through spinal fusion with instrumentation. Although surgery may be considered in appropriately selected patients with preexisting respiratory failure, Gill and colleagues, Proper nutritional balance is crucial for successful surgical outcomes in patients with neuromuscular scoliosis. 24–12). Patients may have cardiac problems secondary to their deformity and other cardiac issues that are comorbidities of the primary disorder. Reviewing the results of 67 patients, McCarthy and colleagues. 24–2). This procedure was followed by T2 to pelvis posterior instrumentation with completion of L1 and L2 corpectomy posteriorly. The addition of an anterior procedure can assist in the correction of neuromuscular spinal deformity and may be justified in several situations (Fig. In a study by Newton and colleagues,80 the fusion rate achieved with anterior release combined with posterior corrective instrumentation and fusion was found to be comparable between adolescent patients with neuromuscular scoliosis and idiopathic scoliosis at 3-year follow-up.
