A radiological study of 50 patients with thoracic Scheuermann's disease revealed two types of lateral spinal curvature. A total of 43 lateral curves was present in 35 of the patients. Thirteen were apical at the same level as the Scheuermann's kyphosis and were due to vertebral-body wedging in the coronal plane; these curves had a mean Cobb angle of 15 degrees, occurred with equal prevalence in boys and girls and were directed equally to right and left. Thirty curves occurred in regions of compensatory lordosis (mean 5.6 degrees) situated above or, more commonly, below the Scheuermann's kyphosis. These scolioses had a mean Cobb angle of 16 degrees, were more often convex to the right than to the left and were significantly more prevalent in girls than in boys. The presence of these kyphoses and scolioses in the same spine, separated by only a few vertebrae, emphasises the importance of the sagittal plane in idiopathic spinal deformities and strongly suggests that idiopathic scoliosis and Scheuermann's disease share a common pathological process

Aim:

AIS causes a loss of trunk height. This paper documents this loss against sitting height standards and assesses formulae for adjusting height loss back to the standard.

Methods:

A total of 334 patients (84% female) with AIS and no other known systemic disease had sitting height measured. This was compared to standards of sitting height with age and the ratio of height to sitting height with age (HSH).

The corrected height was calculated using published formulae and replotted against these standards.


We investigated the relationship between spinopelvic parameters and disc degeneration in young adult patients with spondylolytic spondylolisthesis. A total of 229 men with a mean age of 21 years (18 to 26) with spondylolytic spondylolisthesis were identified. All radiological measurements, including pelvic incidence, sacral slope, pelvic tilt, lumbar lordosis, sacral inclination, lumbosacral angle (LSA), and sacrofemoral distance, were calculated from standing lateral lumbosacral radiographs. The degree of intervertebral disc degeneration was classified using a modified Pfirrmann scale. We analysed the spinopelvic parameters according to disc level, degree of slip and disc degeneration.

There were significant positive correlations between the degree of slip and pelvic incidence (p = 0.009), sacral slope (p = 0.003) and lumbar lordosis (p = 0.010). The degree of slip and the LSA were correlated with disc degeneration (p < 0.001 and p = 0.003, respectively). There was also a significant difference between the degree of slip (p < 0.001) and LSA (p = 0.006) according to the segmental level of disc degeneration.

Background. Scoliosis is described as a lateral spinal curvature exceeding ten degrees on radiograph with vertebral rotation. Approximately 80% of scoliosis presentations are adolescent idiopathic scoliosis (AIS). Current management for AIS in the UK occurs in Surgeon or Paediatrician-led clinics and can be conservative or surgical. The musculoskeletal assessment and triage of AIS appears well-suited to an advanced physiotherapist practitioner (APP) skill set. The aim of this service evaluation was to scope, develop, implement and evaluate a four-month pilot of an APP-led AIS triage pathway. Method and Results. Spinal Consultant deformity and scoliosis clinics were scoped and observed. Clinic inclusion criteria and a patient assessment form was developed. An APP AIS clinic was set up beside a consultant led clinic. All patients assessed were discussed with a spinal surgeon. Consultant and APP agreement (% of total), waiting times, surgical conversion, and patient satisfaction were reviewed. A clinical competency package was developed for training and development of APPs. A total of 49 patients were seen (20 sessions). Waiting list reduced from 10 weeks to 6 weeks. 45%(n=22) of new patients seen were diagnosed with AIS, 27% (n=6) were directly listed for surgery. Consultant/ APP percentage agreement was high for Cobb angle measurement (82%), management plans (90%), and further diagnostic requests (94%). There were no adverse events and high patient satisfaction levels (n=20), (100% Very satisfied or satisfied) were reported. Conclusion. APP-led AIS clinics can provide similar levels of management and assessment as Spinal Consultants with improved waiting times and high levels of satisfaction. Conflicts of interest: No conflicts of interest. Sources of funding: No funding obtained

The aim of this study is to clarify the implication of ciliary pathway on the onset of the spinal curvature that occurs in Adolescent Idiopathic Scoliosis (AIS) patients through functional studies of two genes: POC5 and TTLL11. Since the genetic implication for AIS is accepted, many association and candidate gene analysis revealed the implication of ciliary genes. The characterisation of these two proteins was assessed by qPCR, WB and immunofluorescence in vitro using control cells and cells derived from AIS patients. The impact of genetic modification of these genes on the functionality of the proteins in vitro and in vivo was analysed in zebrafish model created by CRISPR/Cas9 using microCT and histologic analysis. Our study revealed that mutant cells, for both gene, were less ciliated and the primary cilia was significantly shorter compared to control cells. We also observed a default in cilia glutamylation by immunofluorescence and Western Blot. Moreover, we observed in both zebrafish model, a 3D spine curvature similar to the spinal deformation in AIS. Interestingly, our preliminary results of immunohistology showed a retinal defect, especially at the cone cell layer level. This study strongly supports the implication of the ciliary pathway in the onset of AIS and this is the first time that a mechanism is described for AIS. Indeed, we show that shorter cilia could be less sensitive to environmental factors due to lower glutamylation and result in altered signalling pathway. Identifying the biological mechanism involved is crucial for elucidating AIS pathogenesis

Linear spinal cord distraction, in animal models, leads to elevated intra-compartmental spinal cord pressure. We developed an in vitro model of distraction, with increasing tensile force, to demonstrate the relationship between the degree of spinal curvature and the proportional elevation of intra-compartmental pressure. Six Porcine spinal sections, two cervical, two thoracic, and two lumbar were harvested from 30kg pigs. These cord sections were individually stretched in a saline solution with increasing tensile force applied. Cord interstitial pressure (CIP) was monitored with an arterial line pressure monitor. The sections were each tested six times fresh, and then thawed and tested an additional six times. An additional ten freshly thawed cords were tested in linear distraction and over forty-five degree and ninety degree curved surfaces with CIP monitoring. Increased tension, by adding increasing weights of distraction, lead to a proportionally elevated CIP in the linear model (R=0.986). We achieved a 99% confidence interval via paired T testing to demonstrate that there was no significant difference between fresh specimens and recently thawed cords. As the degree of spinal curvature increased from a linear model, to a forty-five and ninety degree (cobb) curve, there were significant increases in CIP at the same distraction force. The more significant the curve, the greater the CIP for each increment in distraction force; ninety degree curves produced a 2.3x higher pressure than linear distraction. High cord interstitial pressure (CIP) can be achieved through spinal cord distraction (> 140mm Hg). This CIP is no only directly proportional to tension, but also proportionally magnified by the degree of spinal curvature. It is not affected by freezing/thawing. This may suggest that spinal cord compartment syndrome is a potential mechanism for spinal cord distraction injury, and these distraction pressures are potentially magnified in the setting of scoliosis

Aims. There is no consensus about the best method of achieving equal leg lengths at total hip arthroplasty (THA) in patients with Crowe type-IV developmental dysplasia of the hip (DDH). We reviewed our experience of a consecutive series of patients who underwent THA for this indication. Patients and Methods. We retrospectively reviewed 78 patients (86 THAs) with Crowe type-IV DDH, including 64 women and 14 men, with a minimum follow-up of two years. The mean age at the time of surgery was 52.2 years (34 to 82). We subdivided Crowe type-IV DDH into two major types according to the number of dislocated hips, and further categorised them into three groups according to the occurrence of pelvic obliquity or spinal curvature. Leg length discrepancy (LLD) and functional scores were analysed. Results. Type-I included 53 patients with unilateral dislocation, in which 25 (category A) had no pelvic obliquity or spinal deformity, 19 (category B) had pelvic obliquity with a compensated spinal curvature and nine (category C) had pelvic obliquity and decompensated spinal degenerative changes. Type-II included 25 patients with one dislocated and one dysplastic hip, in which there were eight of category A, 15 of category B and two of category C. Pre-operatively, there were significant differences between the anatomical and functional LLD in type-IB (p = 0.005) and -IC (p < 0.001), but not in type-IA, -IIA or -IIB. Post-operatively, bony LLD increased significantly in types-IB, -IC and -IIB, whereas functional LLD decreased significantly in each type except for IIA. The mean functional LLD decreased from 30.7 mm (standard deviation (. sd. ) 18.5) pre-operatively to 6.2 mm (. sd. 4.4) post-operatively and the mean anatomical LLD improved from 35.8 mm (. sd. 19.7) pre-operatively to 12.4 mm (. sd. 8.3) post-operatively. Conclusion. Pelvic and spinal changes are common in patients with Crowe type-IV DDH and need to be taken into consideration when planning THA, in order to obtain equal leg lengths post-operatively. The principal subdivisions of Crowe type-IV DDH which we describe proved effective in achieving equal leg lengths and satisfactory outcomes. Cite this article: Bone Joint J 2017;99-B:872–9

Background: Back pain is a common complaint in the Western World with a sedentary lifestyle contributing to its recurrence. The aim of this study was to establish differences in lumbar and thoracic posture after a period of unsupported sitting between subjects with a history of back pain but no current symptoms (BP) and those without a history of back pain (NBP). Method: Twenty subjects (10 BP and 10 NBP group) fulfilling specific inclusion criteria were recruited. Ethical approval was obtained from the Institutions Ethical Committee. Following placement of markers on the vertebrae L5, T12 and C7, subjects sat unsupported on a plinth following standardisation of hip and knee position. A digital image (sagittal view) was taken at 1, 5 and 10 minutes. Spinal curvature was measured using Matlab, two-dimensional analysis system. Repeated measures ANOVA with Post Hoc analysis were calculated to determine the differences between groups and time points. Results: The NBP group demonstrated no difference in thoracic or lumbar curvature at 1, 5 and 10 minutes. The BP group showed a statistically significant difference in lumbar spine curvature between one and ten minutes (p=0.006). No significant differences in thoracic curvature in BP group were found (F =.524 p = 0.601). Conclusion: This study showed that subjects with BP demonstrate a change in lumbar curvature following a period of unsupported sitting compared to NBP group. The thoracic kyphosis in both group remained unchanged. Further studies investigating differences in spinal curvature between specific sub-sets of LBP population could provide useful information on sitting postures

Objective: To document an unusual pattern of clinical presentation simulating cerebral palsy and investigate the evolution of spinal deformity in relation to patients’ growth and responsiveness to levodopa therapy. Study Design-Material: A retrospective study was performed including 3 pediatric patients with dopa-responsive dystonia who developed in the course of their disease spinal curvatures. Summary of Background Data: Dopa-responsive dystonia has been recognized as a separate type of idiopathic dystonia with early onset, gradual generalized involvement, diurnal fluctuation of symptoms, spinal malalignment, and remarkable response to levodopa. Nevertheless, it can present with atypical features including prominent spastic elements and intrafamilial variability of expression. Methods: The medical records and radiographs of the 3 patients were reviewed. Results: All 3 siblings were normal at birth and had negative family history of neurological disease or spinal imbalance. Soon they developed progressive neurological impairment with exaggerated spasticity, underestimated dystonic patterns, and marked phenotypic variation, leading to the initial misdiagnosis of spastic-dystonic cerebral palsy of familial inheritance. With further growth, patient 1 and 3 developed spinal deformity, which responded dramatically to levodopa treatment and resolved spontaneously, while the neurological symptoms persistently ameliorated. Patient 2 developed a rigid C-shaped thoracolumbar scoliotic curve measuring at age 10 years 88o; even though she demonstrated considerable overall improvement with levodopa, the spinal curvature remained unresponsive and necessitated surgical correction through a combined anterior-posterior instrumented spinal fusion extending to the sacrum. However, her ambulatory function was preserved. Conclusions: Spinal decompensation is a common manifestation of dopa-responsive dystonia with excellent prognosis if adequate diagnosis and initiation of levodopa treatment are made early. On the contrary, if diagnosis and levodopa treatment are delayed, spinal deformity may progress following the rapid evolution pattern of neuromuscular curves, necessitating surgical intervention. When spinal arthrodesis is required, inclusion of the lumbosacral joint does not preclude latter ambulatory function

Purpose. To investigate associations between sagittal thoracolumbar spine shape with sex and measures of adiposity throughout adulthood. Methods. Thoracolumbar spine shape was characterised using statistical shape modelling on lateral dual-energy x-ray absorptiometry images, recorded for vertebral fracture analysis, of the spine from 1529 participants of the MRC National Survey of Health and Development, acquired at age 60–64 years. Associations between spine shape modes (SM) and 1) sex, 2) contemporaneous measures of overall and central adiposity (indicated by body mass index and waist circumference, respectively), 3) changes in total and central adiposity during earlier stages of adulthood and age at onset of overweight, were investigated. Results. Four of the first eight spine modes (SM) describing lumbar spine shape differed by sex; on average, women had more lordotic spines than men with relatively smaller but caudally increasing anterior-posterior (a-p) vertebral diameters. Greater BMI and waist circumference and earlier onset of overweight were associated with uneven (or snaking) spinal curvatures (SM2) and larger a-p vertebral diameters (SM3). Central adiposity was also associated with larger caudal disc heights (SM4) in women, especially increases between 36–43 years. Conclusions. Sagittal spine shapes differed by sex and associations with overall and central adiposity also differed. Overweight and greater central adiposity earlier in adulthood were particularly important, and were associated with a straighter but more unevenly curved spine with larger vertebrae and caudal discs heights, possibly explained by a chronic effect of increased mechanical loading on the spine. Conflicts of interest: None. Funding received from MRC

Aims

The aim of this study was to evaluate the reliability and validity of a patient-specific algorithm which we developed for predicting changes in sagittal pelvic tilt after total hip arthroplasty (THA).

Methods

This retrospective study included 143 patients who underwent 171 THAs between April 2019 and October 2020 and had full-body lateral radiographs preoperatively and at one year postoperatively. We measured the pelvic incidence (PI), the sagittal vertical axis (SVA), pelvic tilt, sacral slope (SS), lumbar lordosis (LL), and thoracic kyphosis to classify patients into types A, B1, B2, B3, and C. The change of pelvic tilt was predicted according to the normal range of SVA (0 mm to 50 mm) for types A, B1, B2, and B3, and based on the absolute value of one-third of the PI-LL mismatch for type C patients. The reliability of the classification of the patients and the prediction of the change of pelvic tilt were assessed using kappa values and intraclass correlation coefficients (ICCs), respectively. Validity was assessed using the overall mean error and mean absolute error (MAE) for the prediction of the change of pelvic tilt.

In 21 children with myelomeningocele who underwent kyphectomy for congenital kyphosis of the lumbar spine, aortography revealed no case in which the aorta followed the spinal curvature. Many anomalies of the intercostal and segmental arteries were demonstrated which were only in part associated with deformities of the respective vertebral bodies. The kidneys, which were frequently malformed, often lay within the kyphosis and were therefore at risk of operative damage. We conclude that the aorta is not at risk and that aortography is not usually necessary before kyphectomy, except in patients who have undergone prior abdominal surgery. Non-invasive methods (ultrasound, CT or MRI) should be used to detect malpositions and malformations of the kidneys

Aims

This systematic review aims to identify 3D predictors derived from biplanar reconstruction, and to describe current methods for improving curve prediction in patients with mild adolescent idiopathic scoliosis.

Methods

A comprehensive search was conducted by three independent investigators on MEDLINE, PubMed, Web of Science, and Cochrane Library. Search terms included “adolescent idiopathic scoliosis”,“3D”, and “progression”. The inclusion and exclusion criteria were carefully defined to include clinical studies. Risk of bias was assessed with the Quality in Prognostic Studies tool (QUIPS) and Appraisal tool for Cross-Sectional Studies (AXIS), and level of evidence for each predictor was rated with the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach. In all, 915 publications were identified, with 377 articles subjected to full-text screening; overall, 31 articles were included.

Most studies on LBP have focused on adults although many investigations have shown that the roots of LBP lie in adolescence. Several mechanical, physical and behavioral factors have associated with non-specific LBP in adolescents. To our knowledge no previous study has investigated using advanced statistics all previously reported parameters together with psychological and psychosocial factors on LBP in adolescents aged 15–19 years. 688 students aged 16± 1 years from 5 randomly selected high schools participated in this multifactorial study and completed a questionnaire containing questions on daily activity, backpacks carrying, psychological and psychosocial behavior. Anthropometric data as well biplane spinal curvatures together with questionnaire results were included in the analysis using advanced statistics. LBP reported 41% of the participants. Generally, statistically significant correlations were found between LBP(0.002), physical activity(P< 0.001), physician consultation(P=0.024) and depression (P< 0.001) Gender-related differences were shown regarding LBP intensity(P=0.005) and frequency(P=0.013), stress(P< 0.03), depression (P=0.005) and nervous mood(P=0.036) in favor of male students. Male adolescents had continuously energy (P=0.0258) and were calm (P=0.029) in contrast to female counterparts. LBP was gender-related and was less common in adolescents with frequent activity. Adolescent girls with stress, depressive mood and low energy have more LBP than boys that makes physician consultation for LBP more common in female adolescents. Systematic physical activity and control of psychological profile should decrease LBP frequency and intensity

Stature and its components were examined in 143 girls aged 11 to 15 years with adolescent idiopathic scoliosis. Correction was made for loss of height due to the lateral spinal curvature, and the findings were compared with those from 202 healthy girls of similar age. Using three components of stature (suprapelvic, pelvic and subischial heights) we were able to show that the relatively greater stature of girls with adolescent idiopathic scoliosis was due to changes in the pelvis and lower limbs but not significantly in the spine. Suprapelvic height was reduced relative to subischial height; this probably represents the growth pattern of predominantly ectomorphic individuals, reflecting the physique of many of these girls. Pelvic height was disproportionately increased, and this is considered to be a true rather than an apparent difference. Cephalocaudal disproportion involving two segments suggests a common mechanism of causation which is unlikely to be secondary to the scoliosis. These physical features may in some way be associated with a predisposition to progression of the scoliosis

Spinal fusion, ending caudally at L5 rather than at the sacrum, is recommended for selected patients with scoliosis due to Duchenne muscular dystrophy. We present a retrospective review of 48 patients operated on for this condition. Patients having spinal curvature with a Cobb angle of less than 40° and with less than 10° between a line tangential to the superior margins of both iliac crests and a line perpendicular to the spinous processes of L4 and L5, were fused to L5 (38 patients); patients not meeting these criteria were fused to the sacrum (10 patients). Spinal and sitting obliquity increased in patients fused to L5, rather than to the sacrum, but the severity of the worsening obliquity was significantly greater in patients in whom the apex of the curve was below L1. Two of the ten latter patients required revision procedures for worsening obliquity when their pulmonary function deteriorated to less than 25% of predicted values. We recommend fusion to the sacrum for scoliosis in Duchenne muscular dystrophy, especially for patients with an apex to their curve below L1

AIS is present in 3–5% of the general population. Large curves are associated with increased pain and reduced quality of life. However, no information is available on the impact of smaller curves, many of which do not reach secondary care. The objective of this project was to identify whether or not there is any hidden burden of disease associated with smaller spinal curves. The Avon Longitudinal Study of Parents and Children (ALSPAC) is a population-based birth cohort that recruited over 14,000 pregnant women from the Bristol area between 1991–1992 and has followed up their offspring regularly. At aged 15 presence or absence of spinal curvature ≥6degrees was identified using the validated DXA Scoliosis Measure in 5299 participants. At aged 18 a structured pain questionnaire was administered to 4083 participants. Chi-squared was used to investigate any association between presence of a spinal curve at aged 15 and self-reported pain at aged 18 years. Sensitivity analyses were performed by rerunning analyses after excluding those who were told at aged 13 they had a spinal curve (n=27), and using a higher spinal curve cut-off of ≥10degrees. Full data was available for 3184 participants. Of these, 56.8% were female, and 4.2% non-white reflecting the local population. 202 (6.3%) had a spinal curve ≥6degrees and 125 (3.9%) had a curve ≥10degrees. The mean curve size was 12degrees. 140/202 (69.3%) had single curves, and 57.4% of these were to the right. In total 46.3% of the 3184 participants reported aches and pains that lasted for a day or longer in the previous month, consistent with previous literature. 16.3% reported back pain. Those with spinal curves ≥6degrees were 42% more likely to report back pain than those without (OR 1.42, 95%CI 1.00 to 2.02, P=0.047). In addition, those with spinal curves had more days off school, were more likely to avoid activities that caused their pain, were more likely to think that something harmful is happening when they get the pain, and were more afraid of the pain than people without spinal curves (P<0.05). Sensitivity analyses did not change results. We present the first results from a population-based study of the impact of small spinal curves and identify an important hidden burden of disease. Our results highlight that small scoliotic curves that may not present to secondary care are nonetheless associated with increased pain, more days off school and avoidance of activities

There is a close link between the embryological development of the musculoskeletal system and all other main organ systems. We report a prospective series of 202 patients with congenital vertebral abnormalities and document the associated abnormalities in other systems. There were 100 boys and 102 girls. In 153 there were 460 associated abnormalities, a mean of 2.27 abnormalities for each patient. Intravenous pyelography was carried out on 173 patients (85.6%) and ultrasonography on the remaining 29 (14.4%). Patients with genitourinary anomalies were more likely to have musculoskeletal (p = 0.002), gastrointestinal (p = 0.02) and cardiac abnormalities (p = 0.008) than those without genitourinary involvement. A total of 54 (26.7%) had at least one genitourinary abnormality, the most frequent being unilateral renal agenesis. There was urinary obstruction in six (3%). There was no association between genitourinary abnormality and the place of birth, parental age, birth order, level of spinal curvature, or the number, type and side of spinal anomaly. There was, however, a statistically significant association (p = 0.04) between costal and genitourinary abnormalities. The incidence of genitourinary abnormalities (26.7%) was similar to that of previously reported series. The diagnosis of a congenital vertebral abnormality should alert the clinician to a wide spectrum of possible associated anomalies most of which are of clinical importance

Purpose of the study. Monitoring of scoliosis is traditionally done with radiographs which can be associated with an increased risk of cancer secondary to multiple exposures over many years. This study investigates whether lateral asymmetry (LA) from ISIS2 surface topography can predict radiographic cobb angle, to provide an alternative non- invasive means of monitoring scoliosis patients. Methods. A total of 72 untreated patients with scoliosis (77 curves) with a Cobb angle of 55 degrees or less were included in the study. They had clinical assessment, cobb angle measurement taken from a standard radiograph and surface topography done on the same day. The cobb angle were measured by single surgeon using digital PACS system. The surgeon was unaware of the LA score. Lateral asymmetry was measured using ISIS2 surface topography done by a research nurse who was also unaware of the cobb angle as previously described. Lateral asymmetry was calculated using the standard ISIS2 software. A comparison of cobb angle and LA was performed. Linear regression analysis was performed to define an equation predicting Cobb from LA. The predicted Cobb angles were then compared with the measured radiographic Cobb angles using Bland-Altman analysis. All statistical analysis was carried out using R. Results. The regression equation is: Predicted Cobb = 1.04∗LA + 9.972 with a Pearson correlation coefficient of 0.85 for Cobb angles less than 55 degrees. Bland-Altman analysis of the difference between radiographic Cobb and predicted Cobb from LA gave a mean difference of 0.08 degrees, standard deviation of 6.71 degrees and 95% limits of agreement of −13.3 to 13.5 degrees. For cobb angle less than 55 degrees on radiograph, ISIS2 was able to predict the cobb angle within 13 degrees. Conclusion. Cobb angles themselves display poor reliability, estimates ranging from 3 degrees to 10 degrees. Even so, the 95% confidence limits on the prediction of Cobb angle from ISIS2 LA are too wide to use it alone for monitoring spinal curvature. Whether or not LA is capable of monitoring change in curvature will be investigated as more longitudinal data is built up. Ethics approval: None. Interest Statement: None
