[PMID: 38841462 PMCID: PMC11152931 DOI: 10.1016/j.heliyon.2024.e31752] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2023] [Revised: 05/17/2024] [Accepted: 05/21/2024] [Indexed: 06/07/2024] Open
Abstract
Background Mobility impairment limits control of posture and body alignment. This leads to altered body shapes, co-occurring problems with pain and sleep, cardiopulmonary concerns, digestive health issues, and emergent health outcomes, which further complicate functions of daily living. 24-hour posture care management was developed to remedy these challenges by restoring body symmetry. Objective To determine the feasibility of introducing posture care management to a rural-based, medically complex patient population, evaluate response of body symmetry, and examine its impact on pain and sleep quality. Methods This pilot study employed a longitudinal, quasi-experimental study design from March 2016 to September 2018. The posture care management intervention introduced positioning support for use when lying down, a personalized training workshop for caregiver teams, and in-home initial and follow-up assessments to provide materials and collaboratively develop a personalized care plan. Participants were followed pre-post for 6-9 months. Results A total of 73 participants enrolled in the study; 55 (75 %) completed. The majority were male (55 %) with a median age of 11. Most caregivers were immediate family members, and most participants had 1+ diagnosis characterized as a neurodevelopmental disorder. A majority of participants improved body symmetry (56-76 %), and 53 % with comparable information saw improvement in body symmetry with no worsening of pain or sleep quality. Conclusion This study established the feasibility of administering posture care management in North America. These findings provide preliminary evidence of improvements in body symmetry and address concerns that posture care management can interfere with pain and sleep. Future research should consider levels of caregiver engagement and explore remote-monitored options of a posture care management intervention.

Abstract
Spinal deformities are considered an important complication of neuromuscular disorders such as spinal muscular atrophy (SMA). SMA patients typically develop progressive early-onset scoliosis, which is associated with increased functional decline, discomfort, and respiratory dysfunction. Over the second decade of the twenty-first century, a lot has changed in terms of the therapeutic options available to people with SMA. Specifically, the use of pharmaceutical agents such as nusinersen (Spinraza), onasemnogene abeparvovec (Zolgensma), and risdiplam (Evrysdi) has dramatically changed the landscape for SMA patients. These medications significantly alter motor- and respiratory functioning, as well as the natural progression of spinal deformities. When evaluating these agents and their impact on the development of scoliosis and motor functioning, it is important to consider the timing of treatment initiation. In patients treated after they had already developed symptoms, a shift of phenotype to a less severe subtype has been observed. This results in a delay in the onset of scoliosis for the less severe SMA types and an increase in early-onset scoliosis for the severe types in patients who would typically not live to develop scoliosis. Patients who receive treatment before they develop symptoms achieve almost normal motor functioning and will likely have a significant decrease in scoliosis prevalence or at least delay its onset.

Abstract
Scoliosis is a condition where the spine curves sideways, unique to humans due to their upright posture. However, the cause of this disease is not well understood because it is challenging to find a model for experimentation. This study aimed to create a model for human idiopathic scoliosis by manipulating the function of mechanosensitive channels called Piezo channels in zebrafish. Zebrafish were chosen because they experience similar biomechanical forces to humans, particularly in relation to the role of mechanical force in scoliosis progression. Here we describe piezo1 and piezo2a are involved in bone formation, with a double knockout resulting in congenital systemic malformations. However, an in-frame mutation of piezo1 led to fully penetrant juvenile-onset scoliosis, bone asymmetry, reduced tissue mineral density, and abnormal intervertebral discs-resembling non-congenital scoliosis symptoms in humans. These findings suggest that functional Piezo channels responding to mechanical forces are crucial for bone formation and maintaining spine integrity, providing insights into skeletal disorders.

Abstract
BACKGROUND Until the beginning of the 20th century, 'hysterical scoliosis' could be considered an established diagnosis in Middle Europe's German-speaking countries. The responsible physicians claimed that certain cases of scoliosis were caused solely by psychological factors, and they did not distinguish between real scoliosis (e.g. with neuromuscular cause) and abnormal posture caused by psychological reasons. Instead, 'hysterical scoliosis' was obviously believed to be a real scoliosis caused by psychologically induced contractures. OBJECTIVE This study critically discusses the historical diagnosis 'hysterical scoliosis' from today's point of view. MATERIALS AND METHODS This work is based on historical research (including journals and literature) approximately from the time around 1900. Furthermore, it is also based on recently discovered original material. RESULTS The original material is a correspondence between H. Schlesinger and G. Muskat, who published an article about 'hysterical scoliosis' in Schlesinger's journal. CONCLUSIONS Obviously, the underlying medical concepts of 'hysterical scoliosis' were wrong and led to clear diagnostic problems and inaccuracies. 'Hysterical scoliosis' can be considered one of adolescent psychiatry's early fashionable illnesses around the year 1900.

Abstract
This paper explores the efficacy of the cushion fitting technique using foam cut out cushions for off-loading bony prominences in the sitting position, with a particular focus on reducing the high risk of developing pressure injuries among aging wheelchair users. This technique, historically employed at Rancho Los Amigos National Rehabilitation Center, has shown promising results in reducing pressure injuries for patients with spinal cord injuries. However, its widespread adoption remains limited. This manuscript aims to raise awareness about foam cut out cushions, its historical context, and its contemporary relevance by presenting customized solutions for individual patients with specific deformities. Key clinical points are highlighted, emphasizing the importance of skilled clinicians in the fitting process and the need to consider foam cut out cushions alongside other preventive measures. Case examples illustrate successful outcomes, demonstrating improved pelvic stability, posture, and off-loading of bony prominences. By promoting foam cut out cushions as a valuable cushioning option, this manuscript equips clinicians with knowledge to utilize this technique effectively.

Abstract
Neuromodulation by serotonin regulates the activity of neuronal networks responsible for a wide variety of essential behaviours. Serotonin (or 5-HT) typically activates metabotropic G protein-coupled receptors, which in turn initiate second messenger signalling cascades and induce short and long-lasting behavioural effects. Serotonin is intricately involved in the production of locomotor activity and gait control for different motor behaviours. Although dysfunction of serotonergic neurotransmission has been associated with mood disorders and spasticity after spinal cord injury, whether and to what extent such dysregulation is implicated in movement disorders has not been firmly established. Here, we investigated whether serotonergic neuromodulation is affected in spinal muscular atrophy (SMA), a neurodegenerative disease caused by ubiquitous deficiency of the SMN protein. The hallmarks of SMA are death of spinal motor neurons, muscle atrophy and impaired motor control, both in human patients and mouse models of disease. We used a severe mouse model of SMA, that closely recapitulates the severe symptoms exhibited by type I SMA patients, the most common and most severe form of the disease. Together, with mouse genetics, optogenetics, physiology, morphology and behavioural analysis, we report severe dysfunction of serotonergic neurotransmission in the spinal cord of SMA mice, both at early and late stages of the disease. This dysfunction is followed by reduction of 5-HT synapses on vulnerable motor neurons. We demonstrate that motor neurons innervating axial and trunk musculature are preferentially affected, suggesting a possible cause for the proximo-distal progression of disease, and raising the possibility that it may underlie scoliosis in SMA patients. We also demonstrate that the 5-HT dysfunction is caused by SMN deficiency in serotonergic neurons in the raphe nuclei of the brainstem. The behavioural significance of the dysfunction in serotonergic neuromodulation is underlined by inter-limb discoordination in SMA mice, which is ameliorated when selective restoration of SMN in 5-HT neurons is achieved by genetic means. Our study uncovers an unexpected dysfunction of serotonergic neuromodulation in SMA and indicates that, if normal function is to be restored under disease conditions, 5-HT neuromodulation should be a key target for therapeutic approaches.

Abstract
Nusinersen has been shown to improve or stabilize motor function in individuals with spinal muscular atrophy (SMA). We evaluated baseline scoliosis severity and motor function in nusinersen-treated non-ambulatory children with later-onset SMA. Post hoc analyses were conducted on 95 children initiating nusinersen treatment in the CHERISH study or SHINE long-term extension trial. Participants were categorized by baseline Cobb angle (first nusinersen dose): ≤10°, >10° to ≤20°, and >20° to <40° (no/mild/moderate scoliosis, respectively). Outcome measures included the Hammersmith Functional Motor Score-Expanded (HFMSE) and the Revised Upper Limb Module (RULM). Regression analysis determined the relationships between baseline scoliosis severity and later motor function. For children with no, mild, and moderate scoliosis, the mean increase in HFMSE from baseline to Day 930 was 6.0, 3.9, and 0.7 points, and in RULM was 6.1, 4.6, and 2.3 points. In the linear model, a 10° increase in baseline Cobb angle was significantly associated with a -1.4 (95% CI -2.6, -0.2) point decrease in HFMSE (p = 0.02) and a -1.2 (95% CI -2.1, -0.4) point decrease in RULM (p = 0.006) at Day 930. Treatment with nusinersen was associated with improvements/stabilization in motor function in all groups, with greater response in those with no/mild scoliosis at baseline.

Abstract
BACKGROUND Lower preoperative pelvic obliquity (PO) and L5 tilt have been associated with good radiographic outcomes when the fusion ended short of the pelvis in children with neuromuscular scoliosis (NMS). Our purpose was to identify indications to exclude the pelvis in children with hypotonic NMS treated with growth-friendly instrumentation. METHODS This was a multicenter retrospective review. Children with spinal muscular atrophy and muscular dystrophy treated with dual traditional growing rod, magnetically controlled growing rod, or vertical expandable prosthetic titanium rib with minimum 2-year follow-up after the index surgery were identified. RESULTS A total of 125 patients met the inclusion criteria. Thirty-eight patients had distal spine anchors (DSAs) and 87 patients had distal pelvic anchors (DPAs) placed at the index surgery. Demographics and length of follow-up were similar between the groups but there was a greater percentage of DPA patients who were nonambulatory [79 patients (91%) vs. 18 patients (47%), P <0.0001]. Preindex radiographic measures were similar except the DSA patients had a lower PO (11 vs. 19 degrees, P =0.0001) and L5 tilt (8 vs. 12 degrees, P =0.001). Postindex and most recent radiographic data were comparable between the groups. There was no difference in the complication and unplanned returns to the operating room rates.Subanalysis of the DSA group based on ambulatory status showed similar radiographic measures except the ambulatory patients had a lower PO at all time points (preindex: 5 vs. 16 degrees, P =0.011; postindex: 6 vs. 10 degrees, P =0.045; most recent follow-up: 5 vs. 14 degrees, P =0.028). Only 1 ambulatory DSA patient had a PO ≥10 degrees at most recent follow-up compared with 6 nonambulatory DSA patients. Three (8%) DSA patients, all nonambulatory, underwent extension of their instrumentation to the pelvis. CONCLUSIONS Pelvic fixation should be strongly considered in nonambulatory children with hypotonic NMS treated with growth-friendly instrumentation. At intermediate-term follow-up, revision surgery to include the pelvis was rare but DSAs do not seem effective at maintaining control of PO in nonambulatory patients. DSA and DPA were equally effective at maintaining major curve control, and complication and unplanned returns to the operating room rates were similar. LEVEL OF EVIDENCE Level III-therapeutic.

Abstract
Introduction Symmetry is one of the criteria of correct body posture in upright position. The spatial positioning of the pelvic girdle is crucial to it. Functional and structural asymmetries within the lumbo-pelvic-hip complex can have a significant influence on the structure and functions of many human body organs and systems. The aim of the study was to present the results of inclinometer measurements of selected landmarks of the pelvic girdle in young adults aged 19-29. Methods The analysis of occurrence of spatial pelvic asymmetry was based on the authors' original, clinical classification and the significance of the body mass and height for the analyzed asymmetries. The inclinometer measurements of the selected landmarks of the pelvic girdle were performed in a sample consisting of 300 young individuals. Then, the occurrences of the spatial asymmetry of the pelvis were analyzed based on the authors' own clinical classification using alignment symmetry of the iliac crests, the anterior superior iliac spines and the trochanters major as a criterion. All study subjects with asymmetry <1 degree were treated as those with a symmetrical pelvis. Results The significance of gender, body mass and height for the analyzed asymmetries was assessed. Symmetric positioning of the iliac crests was observed in only 32% of the respondents. The iliac crest depression on the left side was more frequently observed - in 41% of the respondents. This occurred more often in women (44%) than in men (38%). In the group of women, the rotated pelvis was the most often observed (39.4%) asymmetry, while for men, it was the oblique pelvis (40%). More detailed analysis by pelvic asymmetry subtypes showed their statistical differentiation between women and men (p < 0.0001). Analysis of moderate rotation of the pelvis for men, were reported slightly higher values but these differences were not statistically significant (p = 0.253). Women, in turn, showed slightly higher mean values but here too, the differences were not statistically significant (p = 0.245). Discussion Asymmetries in the pelvis area are common; they were observed in less than three-quarters of the examined population. Oblique pelvis was found in less than a quarter of women and in more than one-third men with the predominant structural asymmetries. Rotated pelvis was observed in more than one-third of women and men with dominating functional asymmetries. There were no linear correlations between the body mass and height, and the angle of asymmetries.

Abstract
PURPOSE The aim was to investigate the prevalence, characteristics, predictors, and consequences of chronic pain in a national cohort of patients with limb-girdle muscular dystrophy (LGMD). MATERIALS AND METHODS Questionnaires were sent to all Danish LGMD patients (≥18 years of age) registered with the National Rehabilitation Center for Neuromuscular Diseases. RESULTS Of 209 patients, 121 responded. 44.7% of the patients experienced persistent (daily or constant) chronic pain lasting more than 3 months. 21.0% of patients experienced chronic pain that was not daily. Most pain patients experienced three or more pain problems, primarily in the lower back, neck, shoulders, hips, and legs. Symptoms suggestive of neuropathic pain were sometimes present. Patients with persistent chronic pain reported moderate pain interference with daily activities, greater psychological distress, and lower quality of life compared to patients without pain but did not differ regarding physical functioning. Sex, age, LGMD duration, LGMD type, mechanical ventilation use, mobility, arm function, or performance on activities of daily living did not predict chronic pain. CONCLUSION Chronic pain is common in patients with LGMD. Chronic pain should be considered an important component of LGMD and addressed in the clinic and rehabilitation setting from a biopsychosocial perspective.Implication for rehabilitationChronic pain is highly prevalent in patients with limb-girdle muscular dystrophy.Health professionals need to systematically ask patients about pain and the influence of pain on everyday life irrespective of LGMD-duration and extent of muscle wastage.Chronic pain and psychological distress need to be addressed in the clinic and rehabilitation setting as an additional disabling component of LGMD and this should be done within a biopsychosocial framework.

Abstract
Scoliosis is a common spinal deformity that considerably affects the physical and psychological health of patients. Studies have shown that genetic factors play an important role in scoliosis. However, its etiopathogenesis remain unclear, partially because of the genetic heterogeneity of scoliosis and the lack of appropriate model systems. Recently, the development of efficient gene editing methods and high-throughput sequencing technology has made it possible to explore the underlying pathological mechanisms of scoliosis. Owing to their susceptibility for developing scoliosis and high genetic homology with human, zebrafish are increasingly being used as a model for scoliosis in developmental biology, genetics, and clinical medicine. Here, we summarize the recent advances in scoliosis research on zebrafish and discuss the prospects of using zebrafish as a scoliosis model.

Chu ECP. Neuromuscular scoliosis in the presence of spina bifida occulta and a transitional lumbosacral vertebra: A case report. Radiol Case Rep 2022; 17:3260-3265. [PMID: 35818451 PMCID: PMC9270198 DOI: 10.1016/j.radcr.2022.06.033] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2022] [Revised: 06/08/2022] [Accepted: 06/11/2022] [Indexed: 11/10/2022] Open
Abstract
Common and minor birth defects, such as spina bifida occulta (SBO) and lumbosacral transitional vertebra (LSTV), are largely asymptomatic and overlooked. However, it is important for clinicians to consider their potential impacts on spinal stability. Neuromuscular scoliosis (NMS) is an abnormal lateral curvature of the spine that affects children with pre-existing neuromuscular conditions that are often complex to manage. The purpose of this case report is to describe the association of dual lumbosacral anomalies with complicated NMS. A 12-year-old boy was brought to the chiropractor by his mother for a consultation and possible care for the boy's back pain, progressive scoliosis, and long-standing walking abnormality that worsened quickly in the past 12 months. His mother stated that the patient walked on the balls of his left foot instead of putting weight on the heel ever since he started learning to walk. He had visited several pediatricians and neurologists since childhood. No one had been able to solve his problems. Radiographs showed right thoracolumbar curve of Cobb angle 20°, left pelvic obliquity, a cleft in the L5 and S1, and articulation of the transverse processes of L5 with the bilateral sacral alae. The patient was diagnosed with NMS and functional leg length discrepancy attributed to SBO and a LSTV at L5 level. Multimodal chiropractic care and foot orthotics were used. After 18 months of interventions, normal spinal curve, heel-to-toe gait, and posture balance were retrieved successfully. To date, few reports have been published on the impacts of SBO along with LSTV upon the lumbosacral spine. This article will allow a better understanding of the potential impacts of these birth defects and considerable consequences they would have on the growing spine and, therefore, may help to alleviate their impacts.

Front Public Health 2022; 10:983095. [PMID: 36062094 PMCID: PMC9437421 DOI: 10.3389/fpubh.2022.983095] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Accepted: 08/01/2022] [Indexed: 01/25/2023] Open
Abstract
Background The average altitude of Qinghai-Tibetan Plateau is 4,500 m and most of the residents are Tibetan ethnicity. The purpose of this study was to investigate the prevalence of scoliosis and associated factors among children in this region through a scoliosis screening program. Methods A cross-sectional study was preformed between May 2020 and December 2020 in Qinghai-Tibetan Plateau. A total of 9,856 children aged 6-17 years from schools and nearby villages were screened using visual inspection, the Adams forward-bending test, the angle of trunk rotation, and radiography. A self-designed questionnaire was used to collect demographic data. The prevalence of scoliosis and associated factors were analyzed. Results The overall prevalence of scoliosis among children in Qinghai-Tibetan Plateau was 3.69%, with 5.38% for females and 2.11% for males. The prevalence of scoliosis was 3.50% in children resided below 4,500 m while 5.63% in those resided above 4,500 m (P = 0.001). The prevalence of congenital scoliosis (2.14 vs. 0.42%, P < 0.001) and neuromuscular scoliosis (0.34 vs. 0.07%, P = 0.041) were significantly higher in the altitude above 4,500 m. 50.00% of patients resided above 4,500 m were recommended for surgery while 16.24% in those resided below 4,500 m (P < 0.001). Independent associated factors were detected as female (OR = 2.217, 95 CI% 1.746-2.814, P < 0.001), BMI < 18.5 (OR = 1.767, 95 CI% 1.441-2.430, P = 0.005), altitude of residence ≥ 4,500 m (OR = 1.808, 95 CI% 1.325-2.483, P = 0.002), and sleep time < 8 h (OR = 2.264, 95 CI% 1.723-2.846, P = 0.001). Conclusion The prevalence of scoliosis among children in Qinghai-Tibetan Plateau was 3.69%. With increasing altitudes, the prevalence of scoliosis and its major type were different from that at lower altitudes. Female, BMI < 18.5, altitude of residence ≥ 4,500 m, and sleep time < 8 h were independently associated with the prevalence of this disease. Early screening should be carried out before the age of 7 years, especially in the high-altitude, underdeveloped, and rural areas.

Correlation between Scoliosis Flexibility Degree on Preoperative Imaging with Postoperative Curve Correction and Mechanical Complications. APPLIED SCIENCES-BASEL 2022. [DOI: 10.3390/app12147305] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 02/01/2023]
Abstract
(1) Background: In the preoperative planning stage of scoliosis surgery, it is routine to use radiographs obtained with and without traction to observe the curve flexibility in order to estimate curve correction, but its association with mechanical complications is not completely understood. (2) Methods: Retrospective cohort study of all patients undergoing infantile, congenital, neuromuscular or idiopathic adolescent scoliosis correction surgery at a single institution between 2015 and 2019, with a minimum follow-up of 24 months. Associations between qualitative variables were tested with the chi-square test. The association between qualitative and quantitative variables were tested with the Mann–Whitney test, and correlations between quantitative variables was tested with Spearman’s correlation. (3) Results: A total of 330 patients, 88 males and 242 females, with a mean age of 16.98 years at surgery, were included. The mean value of preoperative main curves, its flexibility and postoperative value were 54.44 degrees, 21.73 degrees and 18.08 degrees, respectively. (4) Conclusions: Preoperative spinal X-ray examination with traction or bending films is a reasonable option for assessing scoliotic curve flexibility, and patients with neuromuscular scoliosis who are not ambulatory can be informed of the increased risks of late mechanical complications.

Abstract
Background and Objectives The introduction of spinal muscular dystrophy (SMA)-modifying therapies, such as antisense oligonucleotide therapy, has changed the natural history of SMA. Most reports on treatment outcomes have focused on motor scores and respiratory function. The objective of this study is to document the development and progression of scoliosis in patients with SMA1 treated with nusinersen. Methods A descriptive single-center study was conducted in patients with SMA1 who were treated with nusinersen before 6 months of age. Data were collected on patients who met criteria, including age at the first nusinersen dose, number of nusinersen doses, degree of scoliosis, respiratory parameters, feeding route, and motor scores at baseline and follow-up. The Children's Hospital of Philadelphia Infant Test of Neuromuscular Disorders (CHOP-INTEND) was subanalyzed using axial (AxS) and appendicular motor (ApS) scores to evaluate a possible correlation between scoliosis and axial muscle strength. Results From our cohort, 31 percent (11/35) of patients had a diagnosis of SMA1. Sixty-three percent (7/11) met the inclusion criteria. All patients (7/7) showed initial improvement in their CHOP-INTEND scores in correlation with improvement on the ApS. Despite this, most patients did not show improvement in the AxS. Subsequently, all patients developed scoliosis in the first year of life with Cobb angles that ranged between 18° and 60°. Furthermore, total CHOP-INTEND scores had dropped in 2 patients alongside the development of a Cobb angle of >40°. Discussion Despite the significant improvement in functional motor assessment in patients with SMA1, there is a progression of significant scoliosis despite treatment. Subsequently, lack or minimal improvement on the axial CHOP-INTEND scores may predict worsening on the total motor scores.

Abstract
(1) Background: scoliosis is highly prevalent in children with neurological disorders, however, studies predicting the progression and affecting the direction of scoliosis have been insufficient. We investigated the factors associated with the progression and direction of scoliosis in children with neurological disorders. (2) Method: retrospectively, 518 whole spine radiographs from 116 patients were used for analysis. Factors affecting the progression of scoliosis over time were analyzed using linear mixed-effects model. Factors associated with the apex direction of the scoliosis were analyzed. (3) Results: pelvic obliquity (PO) ≥ 2.5°, gross motor function classification system level V, vertebral rotation, and female sex significantly affect the progression of scoliosis (p = 0.04, <0.001, <0.001, 0.005, respectively). The higher side of PO and the apex side of scoliosis were interrelated (χ² = 14.58, p < 0.001), but the asymmetrical neurological upper extremity involvement was not. (4) Conclusions: severely impaired gross motor function, PO, vertebral rotation, and female sex were significantly related to the progression of scoliosis. The higher side of PO was opposite to the apex side of scoliosis. By identifying the factors that influence the progression of scoliosis, patients at high risk could be more actively intervened to minimize the severe complications.

Abstract
Longevity of individuals with neurodevelopmental diseases as Rett syndrome (RTT) has increased and many reach adulthood and old age. There is therefore a need to increase knowledge about the course of RTT in adults in order to improve medical care management and quality of life. We did a longitudinal study to address if a possible decline in motor skills in adults with RTT can be explained by the presence of common medical conditions as epilepsy, breathing disturbance, and scoliosis. Data from the Danish RTT database, medical files, and videos from visits at the national Center for Rett syndrome were reviewed. The study included 24 individuals aged 30-66 years at last visit after a follow-up period of 6-12 years. Results showed a clinically observable and significant decline in gross motor skills using the Rett syndrome Gross Motor Scale (RSGMS) with a tendency of less decline in the individuals with the best motor abilities. The frequencies of comorbidities were high. Decline in RSGMS score was associated with the presence of epilepsy and severe scoliosis that had been conservatively managed. The results emphasize that epilepsy plays a significant role in the adult RTT life and management of severe scoliosis in the younger years has impact on the motor abilities in adulthood.

Abstract
Deformity due to neuromuscular disease is often progressive and associated with reduced vital capacity. In general, all treatment should be performed in specialized centers, since invasive measures are associated with an increased morbidity compared to adolescent scoliosis. Derived from the etiology and the resulting biomechanical basis (characteristics), important aspects and considerations arise for all healthcare institutions from the examination interval to the duration of conservative therapy and initiation of surgical therapy. Proper monitoring and assessment are key components to identify curve progression and to achieve preservation or improvement of basic functions.

Abstract
Scoliosis is a deformity of the spine caused by excessive lateral curvature. Compared to other variants, neuromuscular scoliosis is more likely to progress, altering the body's normal architecture in a relatively short period of time. Furthermore, patients with Arnold-Chiari malformation or Chiari malformation (CM) type 2 have intrinsic neurological complications that might entangle the initial clinical assessment. A 24-year-old woman with a history of scoliosis and CM type 2 status post-tracheostomy was admitted from a skilled nursing facility after a one-day history of low blood pressure, leukocytosis, and an outpatient chest X-ray suspicious for pneumonia. Physical examination was remarkable for hypotension and decreased breath sounds at the left pulmonary base. A tracheostomy tube and central venous catheter were noticed. Initial laboratory results revealed leukocytosis with borderline bandemia and a chest X-ray with a left lower lung consolidation. She was treated as a case of sepsis, for which broad-spectrum antibiotics were immediately started. However, upon review of charts, the patient's objective findings were similar to a previous admission. Chest computed tomography scan revealed atelectasis in the left lower lung with no signs of consolidation, effusions, or abscesses. After extensive workup, no identifiable cause was found to suggest an acute process. Antibiotic therapy was halted and the patient was discharged to her nursing home. This case presents a patient with CM type 2 and scoliosis complicated by chronic and worsening atelectasis. Accurate initial assessment and communication between providers are paramount to avoid overtreatment.

Abstract
Objectives
The aim of this study was to investigate the relationship between scoliosis and upper extremity functions in patients with Duchenne muscular dystrophy (DMD).
Patients and methods
Between January 2018 and July 2018, a total of 55 patients (54 males, 1 female; mean age: 9.9±2.9 years; range, 6 to 15 years) who were diagnosed with DMD based on the clinical, laboratory, muscle biopsy and molecular analysis results were included in this cross-sectional study. Scoliosis was evaluated and Cobb angles were measured. Functional Ambulation Scale and Brooke and Vignos scale scores were recorded. The ABILHAND-Kids questionnaire and Nine-Hole Peg Test (9-HPT) were used to assess the upper extremity functions. Hand grip strengths were also evaluated.
Results
The median ABILHAND-Kids scores and the hand grip strength values of the patients without scoliosis were significantly higher compared to those with scoliosis (p=0.002 and p=0.004 for right hand and p=0.012 for left hand, respectively). There was no statistically significant difference in the 9-HPT scores between the patients with and without scoliosis (p>0.05). We found a negative, significant correlation between the Cobb angle and ABILHAND-Kids scores in patients with scoliosis (r=-0.503; p=0.017).
Conclusion
Our study results show a moderate relationship between scoliosis and upper extremity functions. Scoliosis may adversely affect upper extremity functions in patients with DMD.

STUDY DESIGN Single-center retrospective cohort analysis. OBJECTIVE The aim of this study was to evaluate risk factors associated with the development of proximal junctional kyphosis (PJK) in pediatric neuromuscular scoliosis (NMS). SUMMARY OF BACKGROUND DATA PJK is a common cause of reoperation in adult deformity but has been less well reported in pediatric NMS. METHODS Sixty consecutive pediatric patients underwent spinal fusion for NMS with a minimum 2-year follow-up. PJK was defined as >10° increase between the inferior end plate of the upper instrumented vertebra (UIV) and the superior end plate of the vertebra two segments above. Regression analyses as well as binary correlational models and Student t tests were employed for further statistical analysis assessing variables of primary and compensatory curve magnitudes, thoracic kyphosis, proximal kyphosis, lumbar lordosis, pelvic obliquity, shoulder imbalance, Risser classification, and sagittal profile. RESULTS The present cohort consisted of 29 boys and 31 girls with a mean age at surgery of 14 ± 2.7 years. The most prevalent diagnoses were spinal cord injury (23%) and cerebral palsy (20%). Analysis reflected an overall radiographic PJK rate of 27% (n = 16) and a proximal junctional failure rate of 7% (n = 4). No significant association was identified with previously suggested risk factors such as extent of rostral fixation (P = 0.750), rod metal type (P = 0.776), laminar hooks (P = 0.654), implant density (P = 0.386), nonambulatory functional status (P = 0.254), or pelvic fixation (P = 0.746). Significant risk factors for development of PJK included perioperative use of halo gravity traction (38%, P = 0.029), greater postoperative C2 sagittal translation (P = 0.030), decreased proximal kyphosis preoperatively (P = 0.002), and loss of correction of primary curve magnitude at follow-up (P = 0.047). Increase in lumbar lordosis from post-op to last follow-up trended toward significance (P = 0.055). CONCLUSION Twenty-seven percent of patients with NMS developed PJK, and 7% had revision surgery. Those treated with halo gravity traction or with greater postoperative C2 sagittal translation, loss of primary curve correction, and smaller preoperative proximal kyphosis had the greatest risk of developing PJK.Level of Evidence: 4.

The prevalence of scoliosis within Belgian myelomeningocele population and the correlation with ambulatory status and neurological comorbidities: a chart audit. Spinal Cord 2021; 59:1053-1060. [PMID: 33495580 DOI: 10.1038/s41393-020-00611-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2020] [Revised: 12/22/2020] [Accepted: 12/23/2020] [Indexed: 11/08/2022]
Abstract
STUDY DESIGN Retrospective chart audit. OBJECTIVES Firstly determining the prevalence of scoliosis in myelomeningocele (MMC) patients of the University Hospitals Leuven. Secondly analyzing whether there are differences concerning distribution of radiological level, ambulatory status, hydrocephalus, tethered cord, and syringomyelia in MMC patients with/without scoliosis. SETTING University Hospitals Leuven, spina bifida convention. METHODS The following data were collected: age, gender, radiograph type, age at the time of the radiograph, position during radiograph, presence of fusion, age at the time of fusion, diagnosis of hydrocephalus, tethered cord, or syringomyelia, radiological level of MMC, ambulatory status, main Cobb angle, main curve convexity, and main curve location. Correlation between prevalence of scoliosis and ambulatory status, neurological comorbidities, and radiological level were investigated. RESULTS There were 116 patients remaining, after excluding patients without MMC or useful images. The scoliosis prevalence in MMC patients was 78.4% (95% CI, 71.0-85.8) for Cobb angle ≥10°; 60.3% (95% CI, 51.4-69.2) for ≥20°, 52.6% (95% CI, 43.5-61.7) for ≥30°, and 36.6% (95% CI, 27.7-45.5) for an angle ≥40°. Wheelchair users had 4 to 8 times more chance of having scoliosis than patients able to walk on all surfaces without aid. Thoracolumbar and lumbar radiological levels had a slightly higher prevalence of scoliosis than sacral levels. CONCLUSIONS The high prevalence of scoliosis warrants a thorough screening and follow-up for MMC. There was no statistically significant difference between hydrocephalus, tethered cord, or syringomyelia regarding scoliosis. Future studies should focus on the interactions of the neurological comorbidities associated with MMC and scoliosis.

Abstract
BACKGROUND Weakness affects motor performance and causes skeletal deformities in spinal muscular atrophy (SMA). Scoliosis surgery decision-making is based on curve progression, pulmonary function, and skeletal maturity. Benefits include quality of life, sitting balance, and endurance. Post-operative functional decline has not been formally assessed. OBJECTIVE To assess the impact of scoliosis surgery on motor function in SMA types 2 and 3. METHODS Prospective data were acquired during a multicenter natural history study. Seventeen participants (12 type 2, 5 type 3 with 4 of the 5 having lost the ability to ambulate) had motor function assessed using the Hammersmith Functional Motor Scale Expanded (HFMSE) performed pre-operatively and at least 3 months post-operatively. Independent t-tests determined group differences based on post-operative HFMSE changes, age, and baseline HFMSE scores. RESULTS Three participants had minimal HFMSE changes (±2 points) representing stability (mean change = -0.7). Fourteen participants lost >3 points, representing a clinically meaningful progressive change (mean change = -12.1, SD = 8.9). No participant improved >2 points. There were no age differences between stable and progressive groups (p = 0.278), but there were significant differences between baseline HFMSE (p = 0.006) and change scores (p = 0.001). Post-operative changes were permanent over time. CONCLUSIONS Scoliosis surgery has an immediate impact on function. Baseline HFMSE scores anticipate post-operative loss as higher motor function scores were associated with worse decline. Instrumentation that includes fixation to the pelvis reduces flexibility, limiting the ability for compensatory maneuvers. These observations provide information to alert clinicians regarding surgical risk and to counsel families.

Abstract
Families of children with medical complexity (CMC) face many types of health-related decisions. These decisions vary in magnitude of consequences, degree of risk, time scale, degree of tradeoffs, degree of uncertainty, degree of linkage with other decisions, and reversibility. There are many influences on decision-making, including evidence, hopes, and values. Primary care pediatricians are in a unique position to assist families of CMC with decision-making. Pediatric clinicians have an opportunity to establish a trusting relationship with a family over time and to understand the family's values, beliefs, and preferences during periods of relative health and stability. This allows primary care pediatricians to support families in decision-making by helping to clarify their values and goals and apply those values to the decision at hand.

Abstract
PURPOSE To determine the prevalence of intraspinal alterations in scoliosis due to Spinal Muscular Atrophy (SMA). METHODS Cross-sectional, observational, descriptive study. Fifty-six patients with SMA diagnosis required surgical treatment due to scoliosis. INCLUSION CRITERIA scoliosis/kyphoscoliosis > 50 degrees in the coronal plane, clinical characteristics of Spinal Muscular Atrophy, accurate diagnosis by means of molecular or genetic study. Prior to the spinal surgery, and to find related intraspinal alterations, MRI of the spine and posterior cranial fossa was performed. RESULTS Forty females, 16 males, mean age 11 years (range 6-14 years). 94% of the patients had Spinal Muscular Atrophy type 2. The mean angle value was 81 degrees (range 53-122 degrees) in the coronal plane and 62 degrees (range 35-80 degrees) in the sagittal plane. The prevalence of intraspinal alterations was 1.78%. One patient with cervical hydromyelia and no neurological surgical procedure prior to the spinal deformity surgery was reported. CONCLUSIONS In the context of preoperative planning and strategy of patients with scoliosis due to Spinal Muscular Atrophy, MRI may have not to be requested.

Abstract
OBJECTIVE This study used a 3-point pressure spinal orthosis made of fabric material in neuromuscular scoliosis patients with flexible spinal curve to evaluate the in-brace correction of the spinal curve and to estimate changes in pulmonary function associated with brace wearing. DESIGN Twenty-eight children with neuromuscular scoliosis with spinal curve flexibility of more than 50% were enrolled. A custom-made 3-point pressure spinal orthosis was fitted for each patient. The Cobb angles in sitting and supine positions, forced vital capacity, forced expiratory volume in the first second, and peak cough flow were measured before and after applying spinal orthoses. Each participant recorded the brace wearing duration, and questionnaires on brace tolerance were collected. RESULTS Cobb angles after application of orthosis decreased from 31.0 degrees (interquartile range = 21.9-45.0 degrees) to 16.6 degrees (interquartile range = 10.0-34.0 degrees) in the sitting position and from 13.3 degrees (interquartile range = 4.0-21.0 degrees) to 1.4 degrees (interquartile range = 0.0-19.0 degrees) while supine (P < 0.01, P = 0.04, respectively). Preorthosis and postorthosis application forced vital capacity, forced expiratory volume in the first second, and peak cough flow were unaffected. Caregivers reported improved sitting postures and manual activities. CONCLUSIONS In children with flaccid-type neuromuscular scoliosis, curve correction can be achieved using a simple fabric-type spinal orthosis when applied to patients with flexible scoliosis, without compromising lung function.

Abstract
OBJECTIVE To investigate the efficacy and safety of preoperative halo-gravity traction and 1-stage posterior surgery for the treatment of scoliosis with intramedullary anomalies. METHODS A total of 11 patients with scoliosis with intramedullary anomalies were evaluated. All patients were treated with preoperative halo-gravity traction and 1-stage posterior surgery. The average age was 11.4 years (range, 7-21 years). All patients were followed-up for at least 2 years (mean, 3.5 years; range, 2-5 years). Their radiologic presentations and complications were reviewed. RESULTS The operating time was 7.9 hours, and the intraoperative bleeding amount was 1890 mL. Both the Cobb angle of scoliosis and kyphosis were significantly improved after halo-gravity traction and the operation (P < 0.05). Tethered cords were released, and intraspinal masses (neurofibromatosis and lipoma) were excised. Syringomyelia and split spinal cord malformations were left untreated. None of the patients experienced deterioration in their neurologic status after surgery. No severe complications, such as infection, cerebrospinal fluid leakage, failed internal fixation, or fractured pedicle screws or rods occurred after the operation. There was no deterioration of neurologic function, delayed infection, or pseudoarthrosis during the follow-up visits. CONCLUSIONS Preoperative halo-gravity traction and 1-stage posterior surgery provided patients who had scoliosis and intramedullary anomalies an effective and safe treatment option with few complications.

Abstract
As the potential for a treatment of Duchenne muscular dystrophy (DMD) grows, the need for methods for the early diagnosis of DMD becomes more and more important. Clinical experiences suggest that children with DMD will show some lack of motor ability in the early stage when compared with children at the same age, especially in balance and coordination abilities. Is it possible to quantify the coordination differences between DMD and typically developing (TD) children to achieve the goal of screening for DMD diseases? In this study, we introduced a Local Manifold Structure Mapping approach in phase space and extracted a novel index, relative coupling coefficient (RCC), from gait pattern signals, which were acquired by wearable accelerometers to evaluate the coordination of children with DMD during a walking task. Furthermore, we compared the RCC of 100 children with DMD and 100 TD children in four different age groups and verified the feasibility and reliability of the proposed indices to distinguish children with TD from DMD. T-test results show that, for all age groups, children of the same age with DMD and TD show significant differences in RCC (p < 0.001). Moreover, RCC comprehensively reflects that the coordination ability of DMD patients under walking tasks gradually decreases with age, which is consistent with clinical experience. As a functional biomarker extracted in the phase space of the gait data, the proposed coupling degree index RCC could sensitively distinguish between DMD and TD children at the same age and provide alternative insights and potentially valuable tools for the screening of DMD.

Abstract
INTRODUCTION Progressive neuromuscular spinal deformities with pelvic obliquity and loss of sitting balance are typical features of severely affected patients with cerebral palsy. The pelvis represents the key bone between the spine and the lower extremity when it comes to deciding whether and when to operate and if spine or hip surgery first is beneficial. The pelvis can be looked at as the lowest vertebra and as the rooftop of the lower extremities. BIOMECHANICAL CONSIDERATIONS To allow for a normal spinal shape, the pelvis needs to be horizontal in the frontal plane and mildly anterior tilted in the sagittal plane, less for sitting and more for standing. Any abnormal pelvic position requires spinal compensation and challenges the equilibrium control of the individual. Both anatomical neighbourhoods - the spine and the hip joints - have to be considered when spinal deformities, hip instability and contractures evolve, in conservative therapy (bracing, physiotherapy, seating in the wheelchair) and when surgical interventions are weighed out against each other. SURGICAL CONSIDERATIONS Multiple anatomical factors such as sagittal profile and pelvic orientiation, pelvic transverse plane asymmetries and lumbosacral malformations have to be considered in case the pelvis is instrumented with sacral and iliac screws. Rotational deformities and asymmetries of the pelvic bones make the safe insertion of long screws challenging. Advantages of primary pelvic fixation include correction of pelvic obliquity, especially considering the lever arm of the whole spinal construct. The risk of revision surgery due to progression of distal curves is also reduced. Disadvantages of pelvic fixation include the complexity of the additional intervention, which may result in longer operating times, increased risk of blood loss, infection and hardware malpositioning.

Abstract
STUDY DESIGN Retrospective. OBJECTIVE Assess the impact of varying severity of BMI on 30-day outcomes following posterior spinal fusions in neuromuscular scoliosis. SUMMARY OF BACKGROUND DATA Obesity in the pediatric population is shown to be associated with adverse outcomes across varying specialties. The weight-outcome relationship in neuromuscular scoliosis has not been thoroughly investigated. METHODS The 2012-2016 American College of Surgeons - National Surgical Quality Improvement (ACS-NSQIP) database was queried using Current Procedural Terminology codes 22800, 22802, and 22804 to identify patients undergoing posterior spinal fusion for neuromuscular scoliosis only. BMI was classified into four groups based on the Center for Disease Control (CDC) BMI-for-age percentile chart - Normal weight (BMI ≥5th to <85th percentile), Underweight (<5th percentile), Overweight (≥85th to <95th percentile) and Obese (≥95th percentile). Multivariate regression models were built to understand the impact of varying BMI severity classes on 30-day outcomes. RESULTS A total of 1291 patients underwent posterior spinal fusion for neuromuscular scoliosis. A total of 695 (53.8%) were normal weight, 286 (22.2%) were underweight, 145 (11.2%) were overweight, and 165 (12.8%) were obese. Obese patients versus normal weight patients were at a significantly higher risk of surgical site infections (OR 2.15; P = 0.035), wound dehiscence (OR 1.58; P = 0.037), urinary tract infections (OR 3.41; P = 0.010), and 30-day readmissions (OR 1.94; P = 0.029). Of note, overweight versus normal weight individuals had higher odds of cardiopulmonary complications (OR 8.82; P = 0.024). No significant associations were seen for varying BMI and other 30-day outcomes. CONCLUSIONS Obese neuromuscular patients undergoing PSF have higher odds of experiencing adverse outcomes, particularly surgical site infections, urinary tract infections, and readmissions. Providers should promote prevention strategies, such as dietary modification and/or early physical activity in these high-risk patients to minimize the risks of experiencing complications in the acute postoperative period.

Abstract
Historically pediatric scoliosis represents a condition deeply rooted within the origins of orthopedic surgery. Today only a few subspecialized surgeons treat pediatric scoliosis patients. In severe cases surgery can hold progression of and correct pathologic spinal curvature. The goal of this article is to provide an overview of the current state of pediatric scoliosis management. It aims to increase the attention of general physicians and orthopedic surgeons to a niched but rather frequently encountered pediatric pathology to facilitate early recognition and diagnosis. A thorough research of literature was conducted to summarize the different scoliosis types, their etiology and presentation. Classification, normal human growth phases and curve progression risk have been further elaborated. Finally, current treatment options with their benefits, shortcomings and complications were laid out and discussed. Among the etiological groups a focus was put on idiopathic scoliosis, in particular adolescent idiopathic scoliosis as the most frequently encountered subtype.

Abstract
Ninety-eight percent of skeletally immature patients with spinal cord injury (SCI) suffer from progressive neuromuscular scoliosis (NMS). Operative treatment has typically been limited to posterior spinal fusion (PSF), but a newer technique as described may be less invasive and preserve more function. A PSF of the entire spine to the pelvis is standard of care. However, maintenance of spinal flexibility, motion, and potential growth is desirable. We present a case for proof-of-concept of utilizing a surgical motion-preserving technique to treat progressive NMS in an 11year-old girl with T10 level (AIS B) paraplegia with a progressive 60° NMS of the lumbar spine. She had anterior scoliosis correction (ASC) from T11-L5 without fusion. Over 24 months, the curve growth-modulated to a residual of 12° with continued modulation to 7° at 3-year follow-up (skeletal maturity).

BACKGROUND Despite an increasing trend of corrective surgery in patients with neuromuscular scoliosis, evidence regarding risk factors associated with non-home discharge destination following surgery remains limited. METHODS The 2012-2016 American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) Pediatric database was queried using Current Procedural Terminology codes for patients undergoing posterior spinal fusion (22802, 22804 and 22808) for neuromuscular scoliosis. Non-home discharge was defined as discharge to a skilled nursing facility, rehabilitation facility and/or separate acute care unit. Patients who expired during inpatient stay were excluded from the study sample. Only patients aged 2-18 years with a primary diagnosis of neuromuscular scoliosis were included in the final cohort. RESULTS Out of a total of 1,269 patients, 76 (6.0%) had a non-home discharge disposition. Following adjustment for baseline clinical characteristics, patients lying in the age bracket of 15-17 years {odds ratio (OR) 2.27 [95% confidence interval (CI): 1.01-5.08]; P=0.047} or >17 years [OR 2.29 (95% CI: 1.10-4.79); P=0.027], male gender [OR 1.75 (95% CI: 1.06-2.89); P=0.029], having structural pulmonary abnormality at time of surgery [OR 2.01 (95% CI: 1.17-3.43); P=0.011], a length of stay >4 days [OR 2.29 (95% CI: 1.15-4.55); P=0.018] and having a past history of childhood cancer [OR 4.50 (95% CI: 1.15-17.61); P=0.031] were significant independent predictors associated with a non-home discharge. CONCLUSIONS Providers can utilize these data to pre-operatively identify patients who might require continued high-level/inpatient care in a facility, and subsequently expedite discharge and reduce costs associated with a prolonged inpatient stay.

Surgeon and Caregiver Agreement on the Goals and Indications for Scoliosis Surgery in Children With Cerebral Palsy. Spine Deform 2019; 7:304-311. [PMID: 30660226 DOI: 10.1016/j.jspd.2018.07.004] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2018] [Revised: 07/03/2018] [Accepted: 07/20/2018] [Indexed: 11/26/2022]
Abstract
STUDY DESIGN Prospective multicenter comparative study. OBJECTIVES We aimed 1) to survey surgeons and caregivers to rank the surgical indications for spinal fusion of pediatric patients with neuromuscular scoliosis secondary to cerebral palsy in order of importance and 2) to characterize the agreement of surgeons and caregivers on major (top three) indications. SUMMARY OF BACKGROUND DATA Surgery for spinal deformity in children with cerebral palsy is a multifaceted and individualized decision that may lead to miscommunication during informed consent. Little data exist on communication effectiveness between surgeon and caregiver during preoperative discussion. METHODS This is a multicenter, prospective survey of Harms Study Group patient caregivers and their surgeons. Participants ranked their most important of 15 indications in descending level of importance, where the top 3 selections were considered major indications for surgery for the particular patient in question. Demographic and other perioperative factors were recorded. Surgeon-caregiver agreement on major indications was determined, taking into account preoperative factors and intersurgeon differences. RESULTS 126 surgeon-caregiver pairs responded. The greatest percentage agreement that an indication was major was "to improve sitting" (69.0% major, 0.8% nonmajor), followed by "to prevent pulmonary compromise" (33.3% major, 24.6% nonmajor), "to improve pain" (31.7% major, 20.6% nonmajor), and "to improve head control/position" (20.7% major, 69.0% nonmajor). Preoperative pain showed an association with surgeon-caregiver agreement on pain as a major indication (p=.004), and intersurgeon differences in agreement on gastrointestinal and pain considerations existed (p=.002, p=.007, respectively). CONCLUSIONS Surgeon-caregiver agreement is greater where literature support for a particular surgical indication is strong (ie, spinal fusion's known improvement of sitting posture in children with neuromuscular scoliosis). Stronger literature support may bolster surgeons' confidence in recommending a particular procedure, fostering greater communication, understanding, and agreement on surgical necessity between caregivers and surgeons. LEVEL OF EVIDENCE Level II, prospective comparative study.

Abstract
BACKGROUND The health-related quality of life (HRQoL) was affected in children and adolescents with scoliosis. However, there was lack of study to compare the HRQoL among patients with different types of scoliosis. We aimed to investigate whether the HRQoL differs among patients with idiopathic, congenital, neuromuscular, and syndromic scoliosis. METHODS Children and adolescents with scoliosis were recruited from a single tertiary hospital. The HRQoL, as assessed by the child health questionnaire 50-item parent form, was compared with a reference health sample group using the effect size (ES). Intergroup differences related to scoliosis subtype and severity were explored. RESULTS A total of 67 participants with scoliosis (24 idiopathic, 15 congenital, 15 neuromuscular, and 13 syndromic) were analyzed. The HRQoL in patients with neuromuscular scoliosis was affected the most, in both physical (ES range: 0.97-2.4) and psychosocial domains (ES range: 0.92-2.58). To a lesser extent, the physical (ES range: 0.99-1.13) and psychosocial (ES range: 0.8-1.18) domains were also affected in patients with syndromic scoliosis. The domains of family activities (ES = 1.1), role/social-emotional/behavioral (ES = 0.99), general health perception (ES = 0.94), and self-esteem (ES = 0.87) were affected in patients with idiopathic scoliosis. In contrast, only the general health perception domain (ES = 1.27) was affected in patients with congenital scoliosis. Scoliosis severity correlated with scores in the physical domains and some psychosocial domains, while treatment type correlated with scores in the physical domains only. Scoliosis subtype and severity both affected the physical and psychosocial domains, with a stronger impact for subtype. CONCLUSION Differences in the HRQoL exist among scoliosis subtypes, with neuromuscular scoliosis being most affected. Although the scoliosis subtype and severity both affect the HRQoL, the subtype is more influential than severity.

Abstract
OBJECTIVE This study aims to elucidate surgical risk factors in neuromuscular scoliosis (NMS) with respect to wound site infection after spinal fusion. METHODS A retrospective review was performed of all patients treated surgically for NMS between January 2008 and December 2016 (minimum 6 months' follow-up). A sub-cohort of 60 patients with minimum 2 years of follow-up data was also analyzed. RESULTS In 102 patients (53 boys and 49 girls), the mean age at surgery was 14.0 years (SD ±2.7). Mean follow-up was 2.53 years (±1.66), and mean time to presentation of infection was 2.14 months (±4.95). The overall perioperative complication rate was 26.5%, with 14.7% of patients developing deep wound infection. Gram-negative bacteria were responsible for 60% of infections; 20% were Gram positive, and 20% involved both types. Pulmonary comorbidities (p = 0.007), pre- to postoperative increase in weight (p = 0.010), exaggerated lumbar lordosis at follow-up (p = 0.008), history of seizures (p = 0.046), previous myelomeningocele repair (p = 0.046), and previous operations (p = 0.013) were significant risk factors for infection. CONCLUSION Our data suggest that in the pediatric population treated surgically for NMS, wound infection is strongly associated with postoperative increase in body weight, residual lumbar lordosis, pulmonary comorbidity, history of myelomeningocele repair, seizures, and previous operations.

Abstract
OBJECTIVE High rates of perioperative complications are associated with deformity correction in neuromuscular scoliosis. The current study aimed to evaluate complications associated with surgical correction of neuromuscular scoliosis and to characterize potential risk factors. METHODS Data were retrospectively collected from a single-center cohort of 102 consecutive patients who underwent spinal fusions for neuromuscular scoliosis between January 2008 and December 2016 and who had a minimum of 6 months of follow-up. A subgroup analysis was performed on data from patients who had at least 2 years of follow-up. Univariate and multivariate regression analyses, as well as binary correlational models and Student t-tests, were employed for further statistical analysis. RESULTS The present cohort had 53 boys and 49 girls with a mean age at surgery of 14.0 years (± 2.7 SD, range 7.5-19.5 years). The most prevalent diagnoses were cerebral palsy (26.5%), spinal cord injury (24.5%), and neurofibromatosis (10.8%). Analysis reflected an overall perioperative complication rate of 27% (37 complications in 27 patients), 81.1% of which constituted major complications (n = 30) compared to a rate of 18.9% for minor complications (n = 7). Complications were predicted by nonambulatory status (p = 0.037), increased intraoperative blood loss (p = 0.012), increased intraoperative time (p = 0.046), greater pelvic obliquity at follow-up (p = 0.028), and greater magnitude of sagittal profile at follow-up (p = 0.048). Pulmonary comorbidity (p = 0.001), previous operations (p = 0.013), history of seizures (p = 0.046), diagnosis of myelomeningocele (p = 0.046), increase in weight postoperatively (p < 0.005), and increased lumbar lordosis at follow-up (p = 0.015) were identified as risk factors for perioperative infection. CONCLUSIONS These results suggest that in neuromuscular scoliosis, patients with preexisting pulmonary compromise and greater intraoperative blood loss have the greatest risk of experiencing a major perioperative complication following surgical deformity correction.

Abstract
PURPOSE Neuromuscular scoliosis (NS) is a complicated spinal disorder, and it could be treated through posterior-only approach (POA) or combined anterior-posterior approach (APA), which one is better and how to choose the surgical tactic is still in controversy. So comparing POA with APA parameters in the treatment of NS is meaningful. METHODS Database of PubMed, Embase and Cochrane Library was systematically searched, and the studies, which focus on the comparisons of POA and APA in the treatment of NS, were included. The meta-analysis was performed by RevMan 5.3. RESULTS Seven retrospective studies with 602 patients were included in meta-analysis. In previous analysis, statistically significant differences were observed in the major parameters between APA and POA. However, the results of subgroup meta-analysis, which focused on the correction angle and loss angle to eliminate the influence of different preoperative angles, were tend to no difference between two groups, except loss angle of scoliosis (MD, 6.4; 95% CI - 0.19 to 13) and correction angle of pelvic obliquity (MD, - 3.44; 95% CI - 6.71 to - 0.17). CONCLUSIONS Our meta-analysis suggested that POA was similar to APA in the correction of scoliosis in coronal and sagittal planes. However, APA had advantages in the correction of pelvic obliquity and decreasing the loss of angle between postoperation and follow-up in main scoliosis, whereas POA had advantages in operative time, blood loss, duration of hospital stay and complications.

Abstract
STUDY DESIGN This is a cross-sectional study. OBJECTIVE To investigate the feasibility and safety of a novel iliosacral screw placement for sacrum-pelvis in adult pelvis by computed tomography (CT) reconstruction. SUMMARY OF BACKGROUND DATA The optimal technique of spino-pelvic fixation is still being developed and redefined. However, neither the relevant anatomic parameters nor the potential spinal canal involvement for a novel iliosacral screw placement have been clearly analyzed. METHODS A total of 60 adults with normal pelvis, with the age ranging from 24 to 79 years old, were included in this study. Based on three-dimensional (3D) CT reconstruction of each pelvis, virtual iliosacral screw channel was identified bilaterally, the trajectory of which was characterized with the optimal width and length from the ilium to the sacrum. The virtual iliosacral screw channel that holding the greatest width and length of osseous channel was measured by rotating the 3D pelvis. Measurements of the determined channel on either side included iliosacral-screw-related and connector-related parameters. RESULTS There was a virtual iliosacral screw channel passing through the ilium, the iliosacral joint and then into the sacrum on either side of each pelvis. The caudal angle, convergent angle, and maximal length were 16.3 ± 3.0°, 61.3 ± 5.9°, 97.0 ± 5.6 mm in male, respectively. In female, they were 16.4 ± 3.9°, 63.0 ± 5.5° and 96.2 ± 6.0 mm, respectively. The ideal direction of the connector was from posteromedial to anterolateral. The cephalad angle, divergent angle, and embedding depth of the connector were 28.0 ± 5.7°, 28.7 ± 5.9° and 19.0 ± 2.9 mm in male, respectively. In female, they were 26.7 ± 6.1°, 27.0 ± 5.5° and 16.4 ± 2.6 mm, respectively. CONCLUSION It is safe and feasible to place the iliosacral screw when performing this novel instrumentation. Preoperative CT imaging and 3D reconstructions may help to determine the correct entry point and the trajectory of iliosacral screw. LEVEL OF EVIDENCE 5.

Abstract
BACKGROUND Trunk control is essential during seated activities. The trunk interacts with the upper extremities (UE) and head by being part of a kinematic chain and by providing a stable basis. When trunk control becomes impaired, it may have consequences for the execution of UE tasks. AIM To review trunk involvement in body movement and stability when performing seated activities and its relation with UE and head movements in neurological patients with a flaccid trunk, with a focus on childhood and development with age. METHODS AND PROCEDURES A search using PubMed was conducted and 32 out of 188 potentially eligible articles were included. OUTCOMES AND RESULTS Patients with a flaccid trunk (e.g. with spinal cord injury or cerebral palsy) tend to involve the trunk earlier while reaching than healthy persons. Different balance strategies are observed in different types of patients, like using the contralateral arm as counterweight, eliminating degrees of freedom, or reducing movement speed. CONCLUSIONS AND IMPLICATIONS The key role of the trunk in performing activities should be kept in mind when developing interventions to improve seated task performance in neurological patients with a flaccid trunk.

Pseudarthrosis in adult and pediatric spinal deformity surgery: a systematic review of the literature and meta-analysis of incidence, characteristics, and risk factors. Neurosurg Rev 2018; 42:319-336.

Abstract
We conducted a systematic review with meta-analysis and qualitative synthesis. This study aims to characterize pseudarthrosis after long-segment fusion in spinal deformity by identifying incidence rates by etiology, risk factors for its development, and common features. Pseudarthrosis can be a painful and debilitating complication of spinal fusion that may require reoperation. It is poorly characterized in the setting of spinal deformity. The MEDLINE, EMBASE, and Cochrane databases were searched for clinical research including spinal deformity patients treated with long-segment fusions reporting pseudarthrosis as a complication. Meta-analysis was performed on etiologic subsets of the studies to calculate incidence rates for pseudarthrosis. Qualitative synthesis was performed to identify characteristics of and risk factors for pseudarthrosis. The review found 162 articles reporting outcomes for 16,938 patients which met inclusion criteria. In general, the included studies were of medium to low quality according to recommended reporting standards and study design. Meta-analysis calculated an incidence of 1.4% (95% CI 0.9-1.8%) for pseudarthrosis in adolescent idiopathic scoliosis, 2.2% (95% CI 1.3-3.2%) in neuromuscular scoliosis, and 6.3% (95% CI 4.3-8.2%) in adult spinal deformity. Risk factors for pseudarthrosis include age over 55, construct length greater than 12 segments, smoking, thoracolumbar kyphosis greater than 20°, and fusion to the sacrum. Choice of graft material, pre-operative coronal alignment, post-operative analgesics, and sex have no significant impact on fusion rates. Older patients with greater deformity requiring more extensive instrumentation are at higher risk for pseudarthrosis. Overall incidence of pseudarthrosis requiring reoperation is low in adult populations and very low in adolescent populations.

Abstract
PURPOSE To describe pulmonary function and determine the impact of neurological level, scoliosis, and obesity on pulmonary function in people with spina bifida (SB). METHODS Participants with SB (N= 29) (15 females; age, 30 ± 12 years) completed spirometry and body plethysmographic lung volume testing. Univariate and multivariate regression analyses were used to describe the factors associated with pulmonary function in people with SB. RESULTS Distribution of category of impairment in pulmonary function was: 55% (n= 16) restricted, 6.9% (n= 2) spirometric restricted, 1 combined obstructed and restricted, and 35.5% (n= 10) normal. In univariate analyses, neurological level was negatively associated with pulmonary function parameters, i.e., forced vital capacity (FVC) (p= 0.005), forced expiratory volume in 1 second (FEV1) (p= 0.008), total lung capacity (TLC) (p= 0.001), and degree of scoliosis were inversely associated with FVC (p= 0.005), FEV1 (p= 0.003), and TLC (p= 0.004). In multivariate models, level of lesion and degree of scoliosis independently contributed to the degree of lung function impairment. Restrictive pulmonary function was observed in 9/10 (90%) of those with thoracic neurological levels and was associated with decreased inspiratory capacity (IC) and expiratory reserve volume (ERV). Lumbar level lesions were associated with either normal lung function or an isolated reduction in FVC due to reduction in only ERV and preserved TLC representing spirometric restriction. CONCLUSIONS High prevalence of restrictive pulmonary physiology is present in people with SB, with more rostral neurological levels and greater degree of scoliosis associated with a higher degree of pulmonary function impairment.

Abstract
Providing comprehensive transition care for adolescents and young adults with spina bifida (AYASB) requires a structured approach to addressing chronic condition management, self-management, care coordination, and health care navigation that is adaptable to the various levels of cognitive ability, physical function, and family/community environments within the population. This commentary (1) highlights AYASB transition program needs identified in the literature and within a local community, (2) analyzes advantages and limitations of published AYASB transition care models in addressing these needs, (3) demonstrates how a spina bifida (SB) transition clinic used the Chronic Care Model (CCM) to develop a comprehensive AYASB transition program, and (4) examines the potential feasibility in adapting this model to other SB clinics. A SB-specific transition clinic based on the CCM model facilitates the complex chronic care management and transition planning for AYASB. Further study is needed to evaluate health care outcomes using the CCM for SB transition.

Abstract
PURPOSE To assess reliability and validity of a trunk deformity evaluation method expressed as rotational and lateral lean angles between the upper and the lower trunk and between the lower trunk and the pelvis using 3D positions of six front body surface landmarks. METHODS Inter- and intra-rater reliabilities of the proposed method in adults with typical development (n = 22) were assessed, and its validity was also assessed through correlations between the Cobb angle and the analyzed trunk deformity parameters in adults with severe physical disabilities (n = 22). RESULTS The mean differences between two raters and between the initial and second measures were within 2°. Moderate correlations were found between the Cobb angle and both the upper and the lower trunk lateral lean angle and the upper trunk rotation angle. CONCLUSIONS The proposed trunk deformity evaluation appears to be a reliable and valid approach for bedridden people with physical disabilities.

The use of dynamic elastomeric fabric orthosis suits as an orthotic intervention in the management of children with neuropathic onset scoliosis: A retrospective audit of routine clinical case notes. SCOLIOSIS AND SPINAL DISORDERS 2016; 11:14. [PMID: 27299163 PMCID: PMC4900238 DOI: 10.1186/s13013-016-0073-z] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/25/2015] [Accepted: 05/09/2016] [Indexed: 11/22/2022]
Abstract
Background To date the main treatment approach for neuropathic onset scoliosis has utilised thoracic lumbar sacral orthoses (TLSO) to stabilize the spine and enable stable sitting. Dynamic elastomeric fabric orthoses (DEFOs) may achieve both of these aims if used as an early intervention. Due to a lack of evidence in this area, a retrospective audit of case notes was undertaken to understand current orthotic practice investigating the usage, outcomes and clinical characteristics of treated children with neuropathic onset scoliosis. Clinical notes of 180 children at risk for, or identified with, scoliosis were audited using a search matrix to identify diagnostic group, spinal muscle tone, Gross Motor Functional Classification Scale (GMFCS) level, orthotic treatment modalities, scoliosis specific data, surgical interventions, adaptive technologies used, and outcome measurements reported. Results Of the 180 notes examined, 85 were male; mean age nine years one month [SD four years seven months]. Spinal muscle tone was reported in 137 cases: 122/137 presented as low tone, 4/137 high tone, 6/137 fluctuating tone and 5/137 typical tone. Scoliosis was confirmed in (77/180) of whom (39/77) used a DEFO. Another (43/180) had a spinal curve developing, of whom (22/43) used a DEFO. The remaining (60/180) had no report of spinal curvature, but used a DEFO as a preventative measure. GMFCS scores were reported for 49 children of whom 14/49 were graded as level 4 and 17/49 level 5. Of the children with scoliosis who had spinal curve shapes reported, 48/60 had a C-shape presentation and 12/60 had an S-shape. Conclusions The findings confirm previously reported papers in children with neuropathic onset scoliosis in relation to curve shape and GMFCS levels. It provides some evidence of the role DEFOs may have in the management of these children, and highlights the need for further research in this area due to the lack of peer-reviewed publications.

Abstract
OBJECTIVE The objective of this study was to determine if the recent changes in technology, surgical techniques, and surgical literature have influenced practice trends in spinal fusion surgery for pediatric neuromuscular scoliosis (NMS). In this study the authors analyzed recent trends in the surgical management of NMS and investigated the effect of various patient and surgical factors on in-hospital complications, outcomes, and costs, using the Nationwide Inpatient Sample (NIS) database. METHODS The NIS was queried from 2002 to 2011 using International Classification of Diseases, Ninth Edition, Clinical Modification codes to identify pediatric cases (age < 18 years) of spinal fusion for NMS. Several patient, surgical, and short-term outcome factors were included in the analyses. Trend analyses of these factors were conducted. Both univariate and multivariable analyses were used to determine the effect of the various patient and surgical factors on short-term outcomes. RESULTS Between 2002 and 2011, a total of 2154 NMS fusion cases were identified, and the volume of spinal fusion procedures increased 93% from 148 in 2002 to 286 in 2011 (p < 0.0001). The mean patient age was 12.8 ± 3.10 years, and 45.6% of the study population was female. The overall complication rate was 40.1% and the respiratory complication rate was 28.2%. From 2002 to 2011, upward trends (p < 0.0001) were demonstrated in Medicaid insurance status (36.5% to 52.8%), presence of ≥ 1 comorbidity (40.2% to 52.1%), and blood transfusions (25.2% to 57.3%). Utilization of posterior-only fusions (PSFs) increased from 66.2% to 90.2% (p < 0.0001) while combined anterior release/fusions and PSF (AR/PSF) decreased from 33.8% to 9.8% (< 0.0001). Intraoperative neurophysiological monitoring (IONM) underwent increasing utilization from 2009 to 2011 (15.5% to 20.3%, p < 0.0001). The use/harvest of autograft underwent a significant upward trend between 2002 and 2011 (31.3% to 59.8%, p < 0.0001). In univariate analysis, IONM use was associated with decreased complications (40.7% to 33.1%, p = 0.049) and length of stay (LOS; 9.21 to 6.70 days, p <0.0001). Inflation-adjusted mean hospital costs increased nearly 75% from 2002 to 2011 ($36,805 to $65,244, p < 0.0001). In the multivariable analysis, nonwhite race, highest quartile of median household income, greater preexisting comorbidity, long-segment fusions, and use of blood transfusions were found to increase the likelihood of complication occurrence (all p < 0.05). In further multivariable analysis, independent predictors of prolonged LOS included older age, increased preexisting comorbidity, the AR/PSF approach, and long-segment fusions (all p < 0.05). Lastly, the likelihood of increased hospital costs (at or above the 90th percentile for LOS, 14 days) was increased by older age, female sex, Medicaid insurance status, highest quartile of median household income, AR/PSF approach, long-segment fusion, and blood transfusion (all p < 0.05). In multivariable analysis, the use of autograft was associated with a lower likelihood of complication occurrence and prolonged LOS (both p < 0.05). CONCLUSIONS Increasing use of IONM and posterior-only approaches may combat the high complication rates in NMS. The trends of increasing comorbidities, blood transfusions, and total costs in spinal fusion surgery for pediatric NMS may indicate an increasingly aggressive approach to these cases.

Abstract
STUDY DESIGN Psychometric study. OBJECTIVES To determine the intra- and inter-rater reliability and content validity of the International Spinal Cord Injury (SCI) Musculoskeletal Basic Data Set (ISCIMSBDS). SETTING Four centers with one in each of the countries in Australia, England, India and the United States of America. METHODS A total of 117 participants with a C2 to S1 neurological level and American Spinal Injury Association Impairment Scale A to D injury were recruited. The median (interquartile range) time since injury was 9 years (2-29). Fifty-seven participants were assessed by the same assessor, and 60 participants were assessed by two different assessors on two different occasions to determine the intra- and inter-rater reliability, respectively. Kappa statistics or crude agreement was used to measure reliability. Content validity was assessed through focus group interviews of people with SCI and health-care professionals. RESULTS The intra-rater reliability ranged from κ=0.62 to 1.00 and crude agreement from 75% to 100% for each of the variables on the ISCIMSBDS. The inter-rater reliability ranged from κ=-0.25 to 1.00, with a diverse crude agreement ranging from 0% to 100%. The inter-rater reliability was unsatisfactory for the following variables: 'Date of fracture', 'Fragility fractures', 'Scoliosis, method of assessment', 'Other musculoskeletal problems' and 'Do any of the above musculoskeletal challenges interfere with your activities of daily living (transfers, walking, dressing, showers, etc.)?'. Results from validity discussions implied no major suggestions for changes. CONCLUSION Overall, the ISCIMSBDS is reliable and valid, although 5 of the 12 variables may benefit from further refinement.

Abstract
EOS imaging (EOS System; EOS imaging, Paris, France) enables fast 2-D/3-D imaging of children in standing load-bearing position. Non-ambulatory children with neuromuscular scoliosis need evaluation of their spinal balance while in a normal daily position. We designed a customized chair fitting the EOS patient-area dimensions to obtain images in natural sitting postures. The chair is a 360° rotating orthopaedic chair made of fully radiolucent polyethylene and equipped with an adjustable headrest and three-point belts. Out of 41 consecutive patients, 36 (88%, 95% confidence interval 74-96%) had successful imaging. In most patients with severe neuromuscular trunk deformities, the EOS system combined with our chair was useful for assessing preoperative trunk collapse, pelvic obliquity and postoperative corrections in all planes. This specific device changed our daily practice for the assessment of spinal deformities in non-ambulatory patients.

Genome-wide association study identifies new susceptibility loci for adolescent idiopathic scoliosis in Chinese girls. Nat Commun 2015; 6:8355.

Abstract
Adolescent idiopathic scoliosis (AIS) is a structural deformity of the spine affecting millions of children. As a complex disease, the genetic aetiology of AIS remains obscure. Here we report the results of a four-stage genome-wide association study (GWAS) conducted in a sample of 4,317 AIS patients and 6,016 controls. Overall, we identify three new susceptibility loci at 1p36.32 near AJAP1 (rs241215, Pcombined=2.95 × 10−9), 2q36.1 between PAX3 and EPHA4 (rs13398147, Pcombined=7.59 × 10−13) and 18q21.33 near BCL-2 (rs4940576, Pcombined=2.22 × 10−12). In addition, we refine a previously reported region associated with AIS at 10q24.32 (rs678741, Pcombined=9.68 × 10−37), which suggests LBX1AS1, encoding an antisense transcript of LBX1, might be a functional variant of AIS. This is the first GWAS investigating genetic variants associated with AIS in Chinese population, and the findings provide new insight into the multiple aetiological mechanisms of AIS. The authors perform a genome-wide association study of adolescent idiopathic scoliosis patients of Han Chinese descent, and identify 3 new loci for disease susceptibility.
