ABSTRACT
La escoliosis idiopática del Adolescente (EIA) es una deformidad tridimensional de la columna vertebral que aqueja de diversas formas la condición de vida de quien la padece, afectando el desarrollo físico y psicológico del paciente. Proponemos evaluar el resultado clínico, radiológico y el componente de calidad de vida de pacientes tratados quirúrgicamente con EIA, en el servicio de Neurocirugía, Hospital Jesús Yerena del Lídice. Se evaluó patrón de la curva, clasificación según Lenke, ángulo de Cobb pre y postquirúrgico, edad de tratamiento quirúrgico, gradode corrección, calidad de vida según cuestionario SRS-22 pre y postquirúrgica, valoración funcional mediante la escala de discapacidad de Oswestry (ODI) y complicaciones postoperatorias. Se estudiaron 22 casos (95 % femenino), el principal grupo etario fue de 11-14 años (55 %), la escoliosis tipo 1 fue la predominante (60 %), el ángulo de Cobb inicial fue mayor a 50° (50 %) y la madurez esquelética principal fue Risser 3 (55 %). La edad de resolución quirúrgica predominante fue entre 15-18 años (60 %), el grado de corrección postoperatorio fue de 75-100 % (73 %) y la densidad de los tornillos pediculares fue de 1.4-1.7 (64 %). En el cuestionario SRS-22, hubo mayor afectación en las dimensiones de autoimagen con una media de 1.8 y la valoración por ODI mostró un índice de incapacidad mínima, que fue mejorando en los controles sucesivos. Nuestra principal complicación fueron las infecciones (36 %). Concluimos que la cirugía correctiva temprana en la EIA ofrece a una mejoría clínica, radiológica y de la calidadde vida de estos paciente(AU)
Adolescent idiopathic scoliosis (AIS) is a three-dimensional deformity of the spine that affects the living condition of those who suffer from it in various ways, affecting the physical and psychological development of the patient. We propose to evaluate the clinical and radiological outcome and the quality-of-life component of patients treated surgically with EIA, in the Neurosurgery Service, Hospital Jesús Yerena del Lídice. Curve pattern, Lenke classification, pre-and post-surgical Cobb angle, age at surgical treatment, degree of correction, quality of life according to pre-and post-surgical SRS-22 questionnaire, functional assessment using the Oswestry Disability Scale (ODI) and postoperative complications were evaluated. 22 cases were studied (95% female), the main age group was 11-14 years (55%), type 1 scoliosis was predominant (60%), the initial Cobb angle was greater than 50° (50%) and the main skeletal maturity was Risser 3 (55%). The predominant age of surgical resolution was between 15-18 years (60%), the degree of postoperative correction was 75-100% (73%) and the density of pedicle screws was 1.4-1.7 (64%). In the SRS-22 questionnaire, there was greater impairment in the self-image dimensions with a mean of 1.8 and the ODI assessment showed aminimal disability index, which improved in successive controls. Our main complication was infections (36%). We conclude that early corrective surgery in AIS offers clinical, radiological and quality of life improvement for these patient(AU)

OBJECTIVE@#To observe the alteration of thoracic and lumbar physiological curvature in adolescent idiopathic scoliosis(AIS) and the difference of physiological curvature between different types of scoliosis.@*METHODS@#A retrospective analysis was conducted on 305 adolescent patients taken full spine X-ray in our hospital from January 2017 to December 2021. The patients were divided into normal group and scoliosis group. The normal group was composed of 179 patients, 79 males and 100 females, aged 10 to 18 years old with an average of (12.84±2.10) years old, with cobb agle less than 10 degrees. The scoliosis group was composed of 126 patients, 33 males and 93 females, aged 10 to 18 years old with an average of (13.92±2.20) years old. The gender, age, Risser sign, thoracic kyphosis(TK) and lumbar lordosis(LL) in 2 groups were compared, and the TK and LL were also compared between different genders, different degrees of scoliosis and different segments of scoliosis.@*RESULTS@#The female ratio(P=0.001) and age (P<0.001) in scoliosis group were higher than them in normal group; the ratio of low-grade ossification was higher in normal group than in scoliosis group(P=0.038). TK was significantly smaller in scoliosis group than in normal group(P<0.001), but there was no significant difference in LL between the 2 groups(P=0.147). There were no significant difference in TK and LL between male and female. The TK was significantly bigger in mild AIS patients than in moderate AIS patients(P<0.05), but there was no significant difference in LL between mild and moderate patients(P>0.05). The TK and LL in different segments scoliosis were not found significant difference.@*CONCLUSION@#The physiological curvature of thoracic and lumbar spine is independent of gender. The thoracic physiological curvature becomes smaller in AIS patients, but lumbar curvature remains unchanged. The thoracic physiological curvature in mild AIS patients is greater than that in moderate AIS patients, but the lumbar curvature is almost unchanged between mild and moderate scoliosis and is similar with that in normal adolescent. The alteration of thoracic and lumbar physiological curvature in AIS patients may be related to relative anterior spinal overgrowth, and the specific detailed mechanism needs to be further studied.

BACKGROUND:The distribution of horizontal pressure in adolescent idiopathic scoliosis can be used to evaluate the coronal imbalance.Currently,there are no reports on the characteristics of coronal pressure distribution and its correlation with coronal imbalance. OBJECTIVE:To explore the correlation between coronal pressure variation and coronal imbalance in adolescent idiopathic scoliosis patients. METHODS:A total of 39 adolescent idiopathic scoliosis patients who met the inclusion and exclusion criteria in Lianyungang First People's Hospital from March 2021 to June 2022 were selected as the adolescent idiopathic scoliosis group,and 30 matched healthy volunteers were recruited from the outpatient department as the control group.The horizontal position pressure,folding position pressure,coefficient of variation,and global and trunk pressure variation were measured by the TBED Postural Couch evaluation system.In the adolescent idiopathic scoliosis group,full-length spine radiographs were taken to measure Cobb angle,coronal balance,apical vertebral deviation and Nash-Moe rotation.The characteristics of coronal pressure variation and its correlation with coronal imbalance were analyzed. RESULTS AND CONCLUSION:(1)Compared with the control group,there was no statistically significant difference in the horizontal position pressure and folding position pressure in the adolescent idiopathic scoliosis group(P>0.05),but the global pressure variation and coefficient of variation were significantly increased(all P<0.05).(2)There were differences in both sides of the trunk of the adolescent idiopathic scoliosis group and the control group(P<0.05),and the convex side pressure variation in the adolescent idiopathic scoliosis group was higher than the concave side pressure variation in the left and right side pressure variation in the control group(all P<0.05).(3)The variation of the convex side pressure of the trunk in adolescent idiopathic scoliosis patients was positively correlated with coronal balance intensity(r=0.692,P<0.05),moderately positively correlated with Cobb angle and apical vertebral deviation(r=0.499,0.595,all P<0.05),and weakly correlated with Nash-Moe grade(r=0.377,P<0.05).The variation of the concave side pressure of the trunk was moderately positively correlated with coronal balance(r=0.410,P<0.05),and the rest was weakly correlated or not correlated(P>0.05).(4)These findings indicate that pressure variation may be used as an adjoint assessment tool in patients with mild to moderate scoliosis.

ABSTRACT
BACKGROUND:The study of the lumbar spine and pelvis in patients with Lenke type 5 lordosis is limited to the coronal and sagittal planes,and the three-dimensional relationship between the scoliosis and the pelvis has not yet been clarified. OBJECTIVE:To analyze the effect of lumbar scoliosis on the pelvis in patients with Lenke type 5 lordosis and to study the correlation between the lumbar spine and the three-dimensional spatial position of the pelvis. METHODS:Imaging data of 60 patients with Lenke type 5 lordosis scoliosis admitted to the 3D Printing Reception Center of Shanghai Ninth People's Hospital,Shanghai Jiao Tong University School of Medicine from January 2019 to September 2023 were retrospectively analyzed,including Cobb angle,coronal pelvic tilt,lumbar lordosis,left and right pelvic hip width ratio(sacroiliac-anterior superior iliac spine),spinal rotation angle,pelvic tilt,sacral slope,pelvic incidence,coronal deformity angular ratio,sagittal deformity angular ratio,C7 plumb line-center sacral vertical line,apical vertebral translation,and coronal sacral inclination.The information was summarized as a database.SPSS 22.0 software was used to analyze the data related to the lumbar spine and pelvis of the patients with Lenke type 5 primary lumbar curvature adolescent idiopathic scoliosis using Spearman's correlation analysis and linear regression. RESULTS AND CONCLUSION:(1)Cobb angle was highly positively correlated with coronal deformity angular ratio,apical vertebral translation,and spinal rotation angle(r=0.91,r=0.841,r=0.736).(2)Coronal deformity angular ratio was highly positively correlated with apical vertebral translation(r=0.737),moderately positively correlated with C7 plumb line-center sacral vertical line(r=0.514),and moderately negatively correlated with sagittal deformity angular ratio(r=-0.595).(3)There was a high positive correlation between lumbar lordosis and sagittal deformity angular ratio(r=0.942)and a moderate negative correlation with coronal deformity angular ratio(r=-0.554).(4)There was a moderate positive correlation between Cobb angle with coronal pelvic tilt and coronal sacral inclination(r=0.522,r=0.534)and a moderate positive correlation between C7 plumb line-center sacral vertical line and coronal pelvic tilt(r=0.507).Apical vertebral translation with coronal pelvic tilt and coronal sacral inclination showed a moderate positive correlation(r=0.507,r=0.506).Lumbar lordosis with sacral slope and pelvic incidence showed a moderate positive correlation(r=0.512,r=0.538).Sagittal deformity angular ratio was moderately positively correlated with sacral slope and pelvic incidence(r=0.614,r=0.621).(5)Studies have found that the relative position of the lumbar spine and the pelvis is closely related in the horizontal,sagittal and coronal planes.When the lumbar spine affects scoliosis and is rotated,the relative position of the pelvis will also change to compensate,which indicates that while correcting scoliosis,the correction of the pelvis cannot be ignored.
ABSTRACT
OBJECTIVE:At present,there are a variety of treatment methods for scoliosis using specific exercise therapy,but there is a lack of comparison of efficacy between different specific exercise therapy.This article compared the effectiveness of different specific exercise therapies to treat adolescent idiopathic scoliosis through a network meta-analysis. METHODS:Domestic and foreign electronic databases of relevant studies were searched for randomized controlled trials of specific exercise therapy for adolescent idiopathic scoliosis.Search time was from January 2000 to July 2023.The literature was screened by two reviewers using RevMan 5.4 and Stata 16.0 software to extract data and assess the bias risk of of inclusion studies. RESULTS:(1)This article includes 20 randomized controlled trials with 1 377 patients.Of them,12 studies involved Schroth therapy;2 studies involved BSPTS therapy,and 6 studies involved SEAS therapy.(2)The network meta-analysis indicated that in terms of improving Cobb angle and reducing trunk rotation angle in scoliosis patients,the BSPTS therapy group and Schroth therapy group were better than the conventional control group[WMD=-4.60,95%CI(-8.37,-0.82),P<0.05;WMD=-3.37,95%CI(-4.98,-1.75),P<0.05;WMD=-3.20,95%CI(-5.50,-0.90),P<0.05;WMD=-2.13,95%CI(-3.16,-1.09),P<0.05].The Schroth therapy group performed better than the conventional control group effective in improving the International Society for Scoliosis Research-22 Questionnaire quality of life score[WMD=1.41,95%CI(0.07,2.75),P<0.05]. CONCLUSION:Given the current evidence,BSPTS therapy group and Schroth therapy group were better than the conventional control group in improving Cobb angle and reducing trunk rotation angle.In the comparison of different specific exercise therapies,BSPTS therapy can be preferred to improve Cobb angle and reduce trunk rotation angle in adolescent idiopathic scoliosis patients.In addition,Schroth therapy may be the best treatment to improve the quality of life of adolescent idiopathic scoliosis patients.Limited by the quantity and quality of the included studies,the above conclusions should be interpreted with caution and need more high-quality studies to further validation.
ABSTRACT
Objectives:To assess the efficacy and safety of intravenous use of tranexamic acid(TXA)in re-ducing blood loss during correction surgery for patients with adolescent idiopathic scoliosis(AIS).Methods:The clinical data of 759 AIS patients who underwent posterior corrective fusion surgery at Nanjing Drum Tower Hospital between November 2016 and May 2022 were reviewed retrospectively.There were 544 females and 215 males,with an average age of 14.7±2.1 years.Among the patients,369 patients receiving intra-venous use of TXA during surgery were included in the TXA group,while the other 390 patients receiving the same volume of saline but not TXA were included in the control group.The baseline data(age,gender ratio,Cobb angle,and scoliosis type),pre-and postoperative blood laboratory parameters[hemoglobin(Hb),hematocrit(Hct),platelet count(PLT),prothrombin time(PT),D-dimer,activated partial thromboplastin time(APTT),and fibrinogen(FIB)],blood management indicators(intraoperative blood loss,intraoperative blood trans-fusion,postoperative drainage volume and removal time of drainage tube),and correction-related indicators(pre-and postoperative scoliosis degree,correction rate)and postoperative complications were compared be-tween the two groups.Results:There were no significant differences in baseline data and preoperative blood laboratory parameters between the groups(P>0.05).In TXA group,the intraoperative blood loss(551.7±130.3mL),intraoperative blood transfusion volume(551.3±96.3mL),postoperative drainage volume(468.3±162.5mL),and postoperative drainage time(2.8±0.4d)were all significantly lower than those in the control group(666.7±166.8mL,650.0±138.3mL,550.0±135.1mL,3.1±0.8d,P<0.05).Postoperative D-dimer and PLT in the TXA group were significantly lower than those in the control group(P<0.05),while other blood laboratory parameters showed no significant differences between the two groups(P>0.05).There were no statistically significant differ-ences in scoliosis correction rates,postoperative complication rates between the two groups(P>0.05).Conclusions:The use of TXA in surgery can reduce the perioperative blood loss and transfusion,and improve coagulation status in AIS patients,without increasing the incidence rates of complications.
ABSTRACT
Objectives:To analyze the functional movement characteristics after brace treatment for patients with adolescent idiopathic scoliosis(AIS),and to develop and validate a nomogram model to predict the risk of poor outcome.Methods:AIS patients who were treated with braces at our institution from March 2020 to March 2022 were collected as a training set,and were tested for functional movement before treatment,at initial follow-up and after treatment.The same criteria were used to collect AIS patients who underwent brace treatment in our hospital from April 2022 to August 2022 as the validation set.On the basis of whether the degree of scoliosis progression was＞5° after 1 year of treatment,the patients in the training set were divided into stable(≤5°)and progressive(＞5°)groups.Comparison of data was made between groups.Spearman corre-lation analysis was used to analyze the correlation between variables.Logistic regression model was used to screen the risk factors for poor outcomes.R software was applied to develop a nomogram prediction model.Area under curve(AUC)of receiver operating characteristic(ROC)curve and calibration curve were applied to evaluate the discrimination and accuracy of the model.Internal validation was performed with the model predicted risk values before and after training set Bootstrap self-sampling as the test variables and the actual prognosis of patients as the state variable;External validation of the model was performed after randomization of the validation set Bootstrap self-sampling.Results:A total of 102 patients with AIS were included in the training set.There were 73 cases in the stable group and 29 cases in the progressive group(range of degrees of progression:8° to 27°).The median follow-up time was 15.4 months.Both thoracic and lumbar Cobb angles decreased significantly after treatment(P＜0.05).Rotational stability and push-ups were higher at initial follow-up than before treatment,and scores on bow-step squat,hurdle striding,rotational stability,and push-ups improved after treatment(P＜0.05).There was no significant correlation between functional movement characteristics and Cobb angle(P＞0.05).Pre-treatment Cobb angle≥35°,Risser's sign≥3°,apex rotation≥degree Ⅲ,and spinal length gain≥20mm/year were independent risk factors for scoliosis progression.Lumbar spine bone density≥0.8g/cm2 and spinal flexibility≥50%were protective factors.The total value of the risk of scoliosis progression after brace treatment predicted by the nomogram model was 0.93.The AUCs before and after training set self-sampling were 0.928(95%CI:0.858-0.998)and 0.926(95%CI:0.854-0.997),respectively.The validation set included 37 patients.The external validation AUC for validation set was 0.891(95%CI:0.857-0.998).The calibration curves all showed good degree of fitting.Conclusions:Patients with AIS have poor movement patterns due to spinal restrictions.Brace treatment improves trunk stability and rotational stability,which has good corrective effects on the movement pattern.AIS patients with Cobb angle≥35°,Risser's sign≥3°,apex rotation≥degree Ⅲ,spinal length gain≥20mm/year,lumbar spine bone mineral density＜0.8g/cm2,and spinal flexibility＜50%before treatment who underwent bracing are prone to scoliosis progression.Timely warning shall be made based on the nomogram model and postural correction needs to be supplemented at appropriate time to improve the prognosis of AIS brace treatment.
ABSTRACT
OBJECTIVE@#To analyze the correlation between Cobb angle and spinous process angle (SPA) on X-ray film and body surface in patients with mild to moderate adolescent idiopathic scoliosis(AIS). To explore the possibility of linear SPA to assess scoliosis.@*METHODS@#Retrospective study for correlation of Cobb angle and linear SPA on X-ray film. AIS patients treated and taken full spine anteroposterior X-ray from January 2019 to December 2021 were analyzed correlation of Cobb angle and linear SPA on X-ray film. Prospective study for correlation of Cobb angle and body linear SPA. AIS patients treated and taken full spine anteroposterior X-ray from December 1 to December 9 this year were analyzed correlation of Cobb angle and body linear SPA.@*RESULTS@#A total of 113 AIS patients with age an average of (14.02±2.16) years old(ranged from 10 to 18 years old) were recruited in retrospective study, involving 26 males and 87 females;there were 71 patients with mild AIS and 42 patients with moderate AIS. Cobb angle in AIS patients was significantly inversely associated with SPA(r=-0.564, P<0.001), the linear regression equation was:Cobb angle=169.444-0.878×SPA. Cobb angles in patients with mild scoliosis were significantly and inversely associated with SPA(r=-0.269, P=0.012), the linear regression equation was:Cobb angle=46.832-0.185×SPA. Cobb angles in patients with moderate scoliosis were also clearly correlated with SPA(r=-0.417, P=0.003), the linear regression equation was:Cobb angle=113.889-0.516×SPA. Thirty-eight patients were recruited in prospective study. The mean Cobb angle and body linear SPA were(18.70±6.98)°, ranged from 11.3° to 36.0° and (170.34±4.57)°, ranged from 162.1° to 177.7° respectively. There was significantly negative correlation(r=-0.651, P<0.001), the linear regression equation is:Cobb angle=187.91-0.99×SPA.@*CONCLUSION@#Linear SPA on X-ray film or on the body was significantly negatively correlated with Cobb angles, but the regression equation fits poorly, so it's not suitable for diagnosis of scoliosis;however, linear SPA is appropriate for self-controlled assessment of scoliotic therapy or for dynamic assessment of spinal flexibility.

Objectives:To analyze the clinical efficacy of Cheneau brace in adolescent idiopathic scoliosis(AIS)patients and to discuss the changes of curve type during the treatment.Methods:75 patients with AIS treated with Cheneau brace from October 2016 to November 2021 were included.There were 69 females and 6 males,averaged 11.9±1.0 years old when starting to wear the brace,with a mean initial main curve Cobb angle of 29.8°±8.5° and an initial Risser's sign ≤2.Clinical and imaging data were collected,including age,gender,menarche age,time of daily wear,and full-length radiographs of the spine before initial treatment and at the final follow-up.All the patients were followed up for 1 year after finishing brace treatment.The curve types of the patients were counted using the main curve type and the modified Lenke classification system(mLenke),and changes in curve types and the efficacy of bracing in patients with different curve types were analyzed.Results:After 25.7±10.8 months of brace treatment,the patients averaged 14.2±1.2 years old when finishing brace treatment,and the mean main Cobb angle was 27.6°±12.0°.Among the patients,scoliosis was controlled in 63 while progressed in 12,and 23 patients were treated surgically.The rates of success of brace and control of curve were higher in patients with main lumbar curve than those in patients with main thoracic curve(P=0.043,P=0.003).There was a difference in the rate of brace success and control of curve in patients with each mLenke classification(P＜0.001,P=0.005).The highest rates of brace success and control of curve were found in patients of mLenke type Ⅴ,while mLenke type Ⅳ patients had the lowest success rate of brace treatment success and mLenke type Ⅱ patients had the lowest rate of control of curve.Before and after brace treatment,there was a difference in the proportion of patients with each main curve type(P=0.019),and the proportion of patients with each mLenke classification had no statistical difference(P=0.071).There were differences in the rate of change of curve type in each main curve type and each mLenke classification both(P＜0.001,P=0.020).No significant differences were seen in the rates of success of brace treatment and control of curve between patients with and without change in curve type under the two curve type classifications.Conclusions:The efficacy of Cheneau brace varies among AIS patients with different curve types.Patients with a main thoracic curve tend to have a poor response to bracing compared with patients of main lumbar curve;During the treatment with Cheneau brace,the patient's curve types may change,and the overall trend of curve type change is upward shifting of the main curve.The rate and outcome of curve type changes vary among patients with different curve types,and curve type changes may also occur in curve controlled or corrected patients.
ABSTRACT
Objective:To investigate the psychosocial behavior status and related factors in patients with adolescent idio-pathic scoliosis(AIS),in order to pay attention to the mental health and provide an empirical evidence of mental health service and rehabilitation for AIS patients. Method:Fifty participants with AIS and 50 matched healthy adolescents were selected.General information of the participants in the two groups was collected.The Scoliosis Research Society-22(SRS-22),the strengths and difficulties questionnaire-self-report(SDQ-S),self-rating anxiety scale(SAS),nine-item patient health ques-tionnaire(PHQ-9)were used to evaluate the quality of life,anxiety,depression and other psychosocial behav-ior of all subjects.Statistical analysis was conducted to determine whether psychosocial behavior was difference between two groups.The correlation between the type and degree of scoliosis and the quality of life and psy-chosocial behavior was further analyzed. Result:The SAS results indicated that the number of participants with different degrees of anxiety in the AIS group was significantly higher than that in the control group(Z=-3.998,P＜0.001);SDQ-S results showed that the scores of partner interaction problems(t=3.168,P=0.002)and prosocial behavior(t=2.529,P=0.013)in AIS group were significantly higher than those in control group.The scores of pain in double-bend patients were lower than those in single-bend patients(t=2.824,P=0.007);The degree of lateral bending(Cobb Angle)was correlated with the mobility(r=-0.283,P=0.008)and psychological status(r=-0.300,P=0.047)of SRS-22,and was positively correlated with the score of PHQ-9(r=0.356,P=0.011). Conclusion:AIS patients have different levels of anxiety,peer interaction problems and poor prosocial behav-ior.It is necessary to be high valued and screened,evaluated and intervened as soon as possible.
ABSTRACT
@#Introduction: Scoliosis is characterized by an abnormal lateral curvature that may occur during a child’s growth period. Early detection and intervention are needed to prevent the progression of abnormal curvatures. While the gold standard for diagnosing idiopathic scoliosis is x-ray imaging, there is a quick and easy way to perform screening, i.e., using a smartphone. A mobile application with a built-in inclinometer and simple scoliosis tests may help detect scoliosis. Therefore, this study aimed to assess the ScoScreen mobile application’s content for early screening of AIS. Methods: We recruited five physiotherapists with more than five years of experience in paediatric and musculoskeletal and one spinal surgeon. The validity of this study was assessed using a content validity form. Content validity was assessed by calculating the Item-level Content Validity Index (I-CVI), Scale-level Content Validity Index (S-CVI), and modified kappa. Results: The results show that the content validity of ScoScreen has an excellent level of content validity (I-CVI=0.83 – 1.00). The average approach’s overall content validity index was high (S-CVI/Ave=0.94). All items in this study were excellent, with the kappa scores greater than 0.74 (kappa= 0.816 – 1). Conclusion: The development of ScoScreen for early screening of AIS was proven to have excellent content validity in this study. As a result, the Scoscreen mobile application is appropriate for early detection of AIS in terms of its content.

ABSTRACT
Objective To evaluate the efficacy of additive manufacturing scoliosis orthosis, by simulation on interaction of the bone, trunk and orthosis using finite element method. Methods Combined with CT data of the patients, three-dimensional (3D) scanning model of the trunk and full length X-ray of the spine, the bone-trunk-orthosis finite element model was established and proved to be effective. The change and development trend of Cobb angle of the main thoracic scoliosis was calculated under different boundary and load conditions. Results The treatment effect of the additive manufacturing scoliosis orthosis was good. With the increase of orthotic preload, the improvement of Cobb angle and pelvic tilt was more obvious. The Cobb angle was expected to decrease by 6.18° after application of 70 N preload to the orthosis for 6 months. In the case of increasing system stiffness, Cobb angle improvement was not obvious and became even worse. Conclusions Additive manufacturing scoliosis orthosis is effective for treating adolescents with immature bones, while for patients with mature or degenerative bones, its treatment effect is poor.
ABSTRACT
@#Introduction: The instantaneous centre of rotation (ICR) is the centre of motion with zero velocity where a rigid body moves in a particular plane. ICR, as a dynamic measurement, gives more accurate results in terms of quality and quantity of the vertebral motions compared to range of motion (ROM). We aimed to determine the effect of thoracic instrumentation on cervical movement of adolescent idiopathic scoliosis (AIS) patients who had undergone thoracic level instrumentation by measuring pre-operative and post-operative ICR change in a pilot study Materials and methods: A total of 25 AIS patients were included in this study. C4-C5 and C6-C7 segmental ICR were determined by pre-operative and post-operative cervical flexion-extension radiographs. In addition, cervical sagittal parameters and global sagittal parameters were investigated. Results: There was no statistically significant change in ICR location post-operatively in both x and y coordinates at C4- C5 segment (p: 0.326 and p: 0.946, respectively) and C6-C7 segment (p: 0.209, p: 0.086, respectively). There was a positive correlation between LCL and C4-C5 ICR y coordinate (r: 0.481), but not with C6-C7 ICR y coordinate (r: -0.2, p: 0.398). T5-T12 kyphosis decreased (p: 0.002) and T1 pelvic angle (0.003), SVA (0.02) and sacral slope (0.049) increased significantly post-operatively. T1S was correlated with LCL (r: 0.595, p: 0.002), T5-T12 kyphosis (r: 0.423, p: 0.035), SVA (r: 0.658, p<0.001) and C2-C7 SVA (r: 0.416, p: 0.039). Conclusion: The ICR for cervical region was not changed post-operatively in AIS patients with thoracic instrumentation. There was no relationship found between the development of post-operative cervical kyphosis or lordosis and ICR, which represents the quality and quantity of intervertebral motion. The T1 vertebra plays a key role for cervical, thoracic, and global parameters interaction.

Objective:To explore the accuracy and repeatability of the smartphone scoliosis screening APP developed by our team in the measurement of the Cobb angle of adolescent idiopathic scoliosis (AIS).Methods:Clinical data of 60 patients with AIS admitted to Department of Spine and Spinal Surgery, Henan Province People′s Hospital from August 2020 to February 2021 were analyzed retrospectively.Three surveyors measured the coronal main curvature Cobb angle, sagittal thoracic kyphosis (TK) angle, thoracolumbar kyphosis (TLK) angle and lumbar kyphosis (LL) angle on whole-spine lateral X-ray films of 60 patients with AIS by means of the protractor, scoliosis screening APP and computerized Picture Archiving and Communication System (PACS). The time and results of each measurement were recorded.The measurement was repeated once after 2 weeks.Paired t-test was used to compare the measurement time of the APP method and the protractor method.Taking the Cobb angle measurement results of the PACS system as the reference standard, the accuracy of Cobb angle measurement by the APP method was analyzed by paired t-test.The repeatability of the surveyor and the consistency between the surveyors was compared by intraclass correlation coefficient (ICC). Results:Among the 60 patients with AIS, there were 17 males and 43 females, aged from 10 to 16 years [(12.2±2.4) years]. The main bends were thoracic curvature (Lenke Ⅰ) in 23 cases, Lenke Ⅱ in 18 cases and thoracolumbar curvature/lumbar curvature (Lenke V) in 19 cases.The APP method took significantly less time to measure the Cobb angle than the protractor method ( P<0.05). There was no significant difference in the Cobb angle measured by the APP method and PACS method ( P>0.05). The results of the coronal main curvature Cobb angle, TK angle, TLK angle and LL angle measured by 3 surveyors through the APP method were all in good agreement (ICC=0.990, 0.988, 0.986, 0.987). The repeatability (ICC 0.973-0.982) of the coronal main curvature Cobb angle, TK, TLK and LL measured twice before and after the APP method were both better that of the protractor method (ICC 0.933-0.954). Conclusions:Compared with the traditional protractor, the smartphone scoliosis screening APP has the advantages of short measurement time, high efficiency, excellent accuracy and good repeatability in measuring the Cobb angle of AIS.
ABSTRACT
Objective:To quantify any correlation between the severity of spinal curvature of an adolescent with idiopathic scoliosis and their cardiopulmonary exercise endurance.Methods:The cardiopulmonary exercise test (CPET) results and the full-length spinal X-rays in a standing position of 64 adolescents with idiopathic scoliosis were reviewed retrospectively. Independent t-tests were used to compare the two datasets obtained from those with left or right thoracic scoliosis. The correlation between the Cobb angle and cardiopulmonary exercise endurance was analyzed using Pearson correlation coefficients, multiple factor linear regression and two-stage linear regression.Results:After adjusting for gender, age, height and weight, the multiple linear regression analysis showed that the Cobb angle was significantly negatively correlated with maximum tidal volume (β=-0.013) and significantly positively correlated with the rate of respiration (β=0.421). The relationship between the Cobb angle and cardiopulmonary exercise endurance was non-linear. With a Cobb angle > 34°, a 1° increase reduces cardiopulmonary exercise endurance by a factor of 1.4 on average. At smaller Cobb angles the corresponding increase is about 0.87 times.Conclusions:The Cobb angle is a negative predictor of ventilation during exercise among adolescents with idiopathic scoliosis. The more severe a patient′s spinal curvature, the lower the cardiopulmonary exercise endurance is likely to be.
ABSTRACT
Objective:To observe the effect of braces combined with insoles on scoliosis and walking performance in patients with adolescent idiopathic scoliosis (AIS). Methods:From September, 2019 to September, 2020, 42 subjects with AIS were selected and randomly divided into brace group (n = 21) and brace combined with insole group (n = 21). Both groups received two-month routine rehabilitation, including braces for 22 to 23 hours a day and gymnastics for 30 minutes a day. The brace combined with insole group additionally wore insoles, at least eight hours a day for two months. Meanwhile, 32 even-aged adolescents were recruited as healthy controls. Firstly, gait and plantar pressure of 42 patients and 32 healthy adolescents were compared to find out abnormal indicators. Secondly, the scoliosis and above abnormal indicators were compared between the brace group and the brace combined with insole group Results:The center of pressure excursion index (CPEI) was higher in AIS group than in the healthy group (F = 3.120, P < 0.05), and there was no significant difference in walking speed, gait cycle and phase between two groups (P>0.05). An obvious imbalanced pressure was observed between the medial and lateral heel of the single foot and the bilateral foot in AIS patients (P < 0.05). After treatment, the Cobb's angle decreased in AIS patients (t > 7.552, P < 0.001), however, no difference was found between the brace group and the brace combined with insole group (t = 0.459, P > 0.05); the CPEI decreased (t = 2.209, P < 0.05), and the pressure in medial and lateral heel as well as the left and right foot tended to be balanced (t > 2.306, P < 0.05) in the brace combined with insole group, and were better than that of the brace group (|t| > 2.319, P < 0.05). Conclusion:Plantar pressure distribution shows obvious local and global asymmetric changes in AIS patients. The efficacy of insoles on the scoliosis is limited, but the insole can effectively improve the abnormal biomechanics and balance the force.
ABSTRACT
Objective:To explore the appropriate use of a self-developed scoliosis rehabilitation robot in treating adolescent idiopathic scoliosis (AIS), and also its safety and effectiveness.Methods:The scoliosis rehabilitation robot consists of a closed-loop pneumatic control system and multi-segment torso, pelvis and upper extremity fixation devices. It provides three-dimensional synchronous correction. Eighteen AIS subjects first received 30min of robot-assisted treatment using the maximum tolerable orthotic force. The angles of their spinal processes were evaluated using ultrasound before the treatment and after 30 seconds, 5 minutes and 30 minutes of treatment, then 5min later. In a second 30sec course of treatment the transverse orthotic force was 10%, 15%, 20%, 25%, and 30% of the patient′s body weight. Any adverse effects were observed and recorded.Results:The robot ran smoothly and could apply intelligent and precise correction. No severe adverse effects were reported. The mean correction of the spinal process angles showed a significant cumulative effect with treatment time, reaching 104% at 30min. The mean process angle correction increased with the applied force. Force at 25% of the patient′s weight produced an average correction of 104% in patients with mild AIS and 65% in those whose AIS was moderate.Conclusion:The scoliosis rehabilitation robot is safe and immediately effective. Setting the transverse force at 25% of a patient′s weight gives the best corrective effect with mild AIS. Moderate AIS requires more force.
ABSTRACT
@#Introduction: Scoliosis is a deformity of the spine that presents with a ‘S’ or ‘C’ curve with the most common type called Adolescent Idiopathic Scoliosis (AIS). The deformity begins unnoticed and can rapidly progress into severe deformation during the adolescent’s growth spurt. Factors such as onset of puberty, dietary intake, physical activity and ethnicity contributes to the development of AIS. Therefore, this study aims to determine the association of these factors with the prevalence of AIS among female school children in Kuala Langat. Methods: A total of 374 students between age 10 and 12 from six different primary schools in Kuala Langat were recruited according to the inclusion criteria. Consent form and questionnaire was distributed to the student’s parents/guardian prior conducting the research. Adam’s Forward Bend Test was performed to measure the rotation of the trunk using a smartphone Scoliometer Application. Results:Out of 374 students, 21 students from schools in Kuala Langat were found positive for AIS with a prevalence rate of 5.6%. However, no association was seen between the student’s age of menarche, dairy intake, frequency in physical activity and ethnicity with the prevalence of AIS. Conclusion: The factors measured in this study showed no association with the prevalence of AIS among school children in Kuala Langat.
