Therapeutic exercises for idiopathic scoliosis in adolescents.

BACKGROUND: Adolescent idiopathic scoliosis (AIS) is a pathology that changes the three-dimensional shape of the spine and trunk. While AIS can progress during growth and cause cosmetic issues, it is usually asymptomatic. However, a final spinal curvature above the critical threshold of 30° increases the risk of health problems and curve progression in adulthood. The use of therapeutic exercises (TEs) to reduce the progression of AIS and delay or avoid other, more invasive treatments is still controversial. OBJECTIVES: To evaluate the effectiveness of TE, including generic therapeutic exercises (GTE) and physiotherapeutic scoliosis-specific exercises (PSSE) in treating AIS, compared to no treatment, other non-surgical treatments, or between treatments. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, four other databases, and two clinical trials registers to 17 November 2022. We also screened reference lists of articles. SELECTION CRITERIA: Randomised controlled trials (RCTs) comparing TE with no treatment, other non-surgical treatments (braces, electrical stimulation, manual therapy), and different types of exercises. In the previous version of the review, we also included observational studies. We did not include observational studies in this update since we found sufficient RCTs to address our study aims. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methodology. Our major outcomes were progression of scoliosis (measured by Cobb angle, trunk rotation, progression, bracing, surgery), cosmetic issues (measured by surface measurements and perception), and quality of life (QoL). Our minor outcomes were back pain, mental health, and adverse effects. MAIN RESULTS: We included 13 RCTs (583 participants). The percentage of females ranged from 50% to 100%; mean age ranged from 12 to 15 years. Studies included participants with Cobb angles from low to severe. We judged 61% of the studies at low risk for random sequence generation and 46% at low risk for allocation concealment. None of the studies could blind participants and personnel. We judged the subjective outcomes at high risk of performance and detection bias, and the objective outcomes at high risk of detection bias in six studies and at low risk of bias in the other six studies. One study did not assess any objective outcomes. Comparing TE versus no treatment, we are very uncertain whether TE reduces the Cobb angle (mean difference (MD) -3.6°, 95% confidence interval (CI) -5.6 to -1.7; 2 studies, 52 participants). Low-certainty evidence indicates PSSE makes little or no difference in the angle of trunk rotation (ATR) (MD -0.8°, 95% CI -3.8 to 2.1; 1 study, 45 participants), may reduce the waist asymmetry slightly (MD -0.5 cm, 95% CI -0.8 to -0.3; 1 study, 45 participants), and may result in little to no difference in the score of cosmetic issues measured by the Spinal Appearance Questionnaire (SAQ) General (MD 0.7 points, 95% CI -0.1 to 1.4; 1 study, 16 participants). PSSE may result in little to no difference in self-image measured by the Scoliosis Research Society - 22 Patient Questionnaire (SRS-22) (MD 0.3 points, 95% CI -0.3 to 0.9; 1 study, 16 participants) and improve QoL slightly measured by SRS-22 Total score (MD 0.3 points, 95% CI 0.1 to 0.4; 2 studies, 61 participants). Only Cobb angle results were clinically meaningful. Comparing PSSE plus bracing versus bracing, low-certainty evidence indicates PSSE plus bracing may reduce Cobb angle (-2.2°, 95% CI -3.8 to -0.7; 2 studies, 84 participants). Comparing GTE plus other non-surgical interventions versus other non-surgical interventions, low-certainty evidence indicates GTE plus other non-surgical interventions may reduce Cobb angle (MD -8.0°, 95% CI -11.5 to -4.5; 1 study, 80 participants). We are uncertain whether PSSE plus other non-surgical interventions versus other non-surgical interventions reduces Cobb angle (MD -7.8°, 95% CI -12.5 to -3.1; 1 study, 18 participants) and ATR (MD -8.0°, 95% CI -12.7 to -3.3; 1 study, 18 participants). PSSE plus bracing versus bracing alone may make little to no difference in subjective measurement of cosmetic issues as measured by SAQ General (-0.2 points, 95% CI -0.9 to 0.5; 1 study, 34 participants), self-image score as measured by SRS-22 Self-Image (MD 0.1 points, 95% CI -0.3 to 0.5; 1 study, 34 participants), and QoL measured by SRS-22 Total score (MD 0.2 points, 95% CI -0.1 to 0.5; 1 study, 34 participants). None of these results were clinically meaningful. Comparing TE versus bracing, we are very uncertain whether PSSE allows progression of Cobb angle (MD 2.7°, 95% CI 0.3 to 5.0; 1 study, 60 participants), changes self-image measured by SRS-22 Self-Image (MD 0.1 points, 95% CI -1.0 to 1.1; 1 study, 60 participants), and QoL measured by SRS-22 Total score (MD 3.2 points, 95% CI 2.1 to 4.2; 1 study, 60 participants). None of these results were clinically meaningful. Comparing PSSE with GTE, we are uncertain whether PSSE makes little or no difference in Cobb angle (MD -3.0°, 95% CI -8.2 to 2.1; 4 studies, 192 participants; very low-certainty evidence). PSSE probably reduces ATR (clinically meaningful) (MD -3.0°, 95% CI -3.4 to -2.5; 2 studies, 138 participants). We are uncertain about the effect of PSSE on QoL measured by SRS-22 Total score (MD 0.26 points, 95% CI 0.11 to 0.62; 3 studies, 168 participants) and on self-image measured by SRS-22 Self-Image and Walter Reed Visual Assessment Scale (standardised mean difference (SMD) 0.77, 95% CI -0.61 to 2.14; 3 studies, 168 participants). Further, low-certainty evidence indicates that 38/100 people receiving GTE may progress more than 5° Cobb versus 7/100 receiving PSSE (risk ratio (RR) 0.19, 95% CI -0.67 to 0.52; 1 study, 110 participants). None of the included studies assessed adverse effects. AUTHORS' CONCLUSIONS: The evidence on the efficacy of TE is currently sparse due to heterogeneity, small sample size, and many different comparisons. We found only one study following participants to the end of growth showing the efficacy of PSSE over TE. This result was weakened by adding studies with short-term results and unclear preparation of treating physiotherapists. More RCTs are needed to strengthen the current evidence and study other highly clinically relevant outcomes such as QoL, psychological and cosmetic issues, and back pain.

Effectiveness of the Bilateral and Bilevel Erector Spinae Plane Block (ESPB) in Pediatric Idiopathic Scoliosis Surgery: A Randomized, Double-Blinded, Controlled Trial.

BACKGROUND: This study aimed to compare the effect of the ultrasound-guided bilateral and bilevel erector spinae plane block (ESPB) on pain scores, opioid requirement, intraoperative motor-evoked potentials (MEPs), and stress response to surgery expressed by the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) versus standard analgesia methods following idiopathic scoliosis surgery. METHODS: This was a prospective, double-blinded, randomized controlled trial. Sixty patients aged 10 to 18 years and physical status ASA 1 or 2 were randomized into 2 equal groups, each receiving an ESPB or sham block. The primary outcome was the pain scores (Numerical Rating Scale, NRS) within 48 hours after spinal correction and fusion surgery for idiopathic thoracic scoliosis. The secondary outcomes were total opioid consumption, NLR, and PLR levels at 12 and 24 hours postoperatively and intraoperative MEPs. RESULTS: ESPB patients presented lower NRS scores, signifying less pain, at all time points (30, 60, 90, 120 min; and 6, 12, 24, and 48 h after surgery), all P <0.0001. The total opioid consumption, the incidence of nausea or vomiting, and the need for remifentanil and propofol during surgery were significantly lower in the ESPB group. The surgery-induced stress response expressed by NLR and PLR was considerably lower in the ESPB group. ESPB did not affect the intraoperative MEP's amplitude. CONCLUSIONS: ESPB is effective for postoperative analgesia, can reduce opioid consumption in patients undergoing scoliosis surgery, and reduces the stress response to surgery. ESPB does not interfere with neuromonitoring. LEVEL OF EVIDENCE: Level I.

Association Between Baby Walker Use and Infant Functional Motor Development.

PURPOSE: The aim of this study was to determine the association between baby walker use and infant motor development, quality of gait, and potential development of lower extremity deformities. METHODS: An anonymous survey was conducted among 6874 parents and legal guardians regarding the use of baby walkers, their children's development, and the occurrence of lower extremity deformities and gait disorders. A total of 969 questionnaires were returned. RESULTS: Baby walkers were used by 15.6% of children. A higher percentage of children who used baby walkers omitted crawling compared with the 10.7% of children who did not use baby walkers. Gait disorders occurred at a similar percentage in both groups. CONCLUSIONS: Use of baby walkers may be associated with infant motor development. Infants who used a baby walker were 3 times more likely to not have crawled for mobility than those who did not use a baby walker.

Update on neuromonitoring procedures applied during surgery of the spine - observational study.

Introduction: Motor evoked potentials (MEPs) are currently considered as a more useful method for neurophysiological intraoperative monitoring than somatosensory evoked potentials in cases of surgery applied to patients with adolescent idiopathic scoliosis. The non-invasive approach is preferred to modify MEP recordings, criticizing, in many cases, the fundamentalism for neurophysiological monitoring based only on needle recordings. The aim of the review is to provide our own experience and practical guidelines with reference to neuromonitoring innovations. Material and methods: Recordings of MEPs with surface electrodes instead of needle electrodes including nerve instead of muscle combinations during neurophysiological monitoring associated with surgical interventions to the spine have become more relevant for pediatric purposes, avoiding the anesthesiology-related influences. Observations on 280 patients with Lenke A-C types of spine curvature are presented before and after the surgical correction. Results: The MEPs recorded from nerves do not undergo fluctuations at different stages of scoliosis corrections and the anesthesia effect more than MEPs recorded from muscles. The use of non-invasive surface electrodes during neuromonitoring for MEP recordings shortens the total time of the surgical procedure without diminishing the precision of the neural transmission evaluation. The quality of MEP recordings during intraoperative neuromonitoring from muscles can be significantly influenced by the depth of anesthesia or administration of muscle relaxants but not those recorded from nerves. Conclusions: The proposed definition of "real-time" neuromonitoring comprises the immediate warning from a neurophysiologist about the changes in a patient's neurological status during scoliosis surgery (especially during pedicle screws' implantation, corrective rods' implantation, correction, distraction and derotation of the spine curvature) exactly during the successive steps of corrective procedures. This is possible due to the simultaneous observation of MEP recordings and a camera image of the surgical field. This procedure clearly increases safety and limits financial claims resulting from possible complications.

The classification of scoliosis braces developed by SOSORT with SRS, ISPO, and POSNA and approved by ESPRM.

PURPOSE: Studies have shown that bracing is an effective treatment for patients with idiopathic scoliosis. According to the current classification, almost all braces fall in the thoracolumbosacral orthosis (TLSO) category. Consequently, the generalization of scientific results is either impossible or misleading. This study aims to produce a classification of the brace types. METHODS: Four scientific societies (SOSORT, SRS, ISPO, and POSNA) invited all their members to be part of the study. Six level 1 experts developed the initial classifications. At a consensus meeting with 26 other experts and societies' officials, thematic analysis and general discussion allowed to define the classification (minimum 80% agreement). The classification was applied to the braces published in the literature and officially approved by the 4 scientific societies and by ESPRM. RESULTS: The classification is based on the following classificatory items: anatomy (CTLSO, TLSO, LSO), rigidity (very rigid, rigid, elastic), primary corrective plane (frontal, sagittal, transverse, frontal & sagittal, frontal & transverse, sagittal & transverse, three-dimensional), construction-valves (monocot, bivalve, multisegmented), construction-closure (dorsal, lateral, ventral), and primary action (bending, detorsion, elongation, movement, push-up, three points). The experts developed a definition for each item and were able to classify the 15 published braces into nine groups. CONCLUSION: The classification is based on the best current expertise (the lowest level of evidence). Experts recognize that this is the first edition and will change with future understanding and research. The broad application of this classification could have value for brace research, education, clinical practice, and growth in this field.

The method for measurement of the three-dimensional scoliosis angle from standard radiographs.

BACKGROUND: Three-dimensional idiopathic scoliosis cannot be accurately assessed with the aid of a single plane parameter - the Cobb angle. We propose a novel method for evaluating the three-dimensional (3D) pattern of scoliosis based on two X-rays (PA and lateral). The proposed method consists of the measurements of the angles between the upper endplate of the upper-end vertebra and the lower endplate of the lower-end vertebra (3D scoliosis angle). METHODS: The 3D-angles of thirty scoliosis curves were measured with either computed tomography (CT) or digitally reconstructed radiographs (DRRs): PA and lateral. CT was used as a reference. In the case of CT, the 3D angle was calculated based on the coordinates of three points situated on the upper endplate and those of three points situated on the lower endplate of the scoliosis curve. In the case of the DRR, the 3D angle was calculated using the four-angle method: the angles formed by the endplates of the curve with the transverse plane. The results were tested with the Student's t-test, and the agreement of measurements was tested with the intraclass correlation coefficient. RESULTS: There was no significant difference between the 3D-angle measurements obtained with DRRs versus CT, p > 0.05. There was, however, a significant difference between the 3D-scoliosis angle and the Cobb angle measurements performed based on the X-rays. The reproducibility and reliability of 3D angle measurements were high. CONCLUSIONS: Based on two standard radiographs, PA and lateral, it is possible to calculate the 3D scoliosis angle. The proposed method facilitates 3D-scoliosis assessment without the use of sophisticated devices. Considering the 3D nature of AIS, the 3D parameters of the spine may help to apply a more effective treatment and estimate a more precise prognosis for patient with scoliosis.

CHD7 gene polymorphisms in female patients with idiopathic scoliosis.

BACKGROUND: The CHD7 (chromosome domain helicase DNA binding protein 7) gene has been associated with familial idiopathic scoliosis (IS) in families of European descent. The CHD7 single-nucleotide polymorphisms have never been studied in Polish Caucasian IS patients. METHODS: The aim of this study was to investigate the relationship of CHD7 gene polymorphisms with susceptibility to or progression of IS in Polish Caucasian females. The study group comprised 211 females who underwent clinical, radiological and genetic examination. The study group was analyzed in three subgroups according to: (1) Cobb angle (Cobb angle ≤30° vs. Cobb angle ≥35°), (2) age of diagnosis (adolescent IS vs. early-onset IS) and (3) rate of progression (non-progressive vs. slowly progressive vs. rapidly progressive IS). The control group comprised 83 females with no scoliosis and with a negative family history who underwent clinical and genetic examination. In total six CHD7 gene polymorphisms were examined. Three polymorphisms (rs1017861, rs13248429, and rs4738813) were examined by RFLP (restriction fragment length polymorphism) analysis, and three were quantified by Sanger sequencing (rs78874766, rs4738824, and rs74797613). RESULTS: In rs13248429, rs78874766, and rs74797613 polymorphisms only the wild allele was present. The rs1017861 polymorphism demonstrated an association with IS susceptibility (p < 0.01). Two polymorphisms, rs1017861 and rs4738813, were associated with curve severity and progression rate (p < 0.05). None of the evaluated polymorphisms in CHD7 gene showed any association with the age of IS onset. CONCLUSIONS: The polymorphism rs1017861 in CHD7 gene showed an association with IS susceptibility. Two polymorphisms (rs1017861 and rs4738813) were associated with curve severity and progression rate. None of the evaluated polymorphisms in CHD7 gene showed any association with the age of IS onset. Further evaluation of CHD7 gene should be considered as IS modifying factor.

Thirty Percent of Female Footballers Terminate Their Careers Due to Injury: A Retrospective Study Among Polish Former Players.

CONTEXT: Female football is becoming an increasingly popular women's team sports discipline around the world. The Women's Football Committee in the Polish Football Association has developed a long-term strategic plan to popularize the discipline across the country and enhance girls' participation. On one hand, it is postulated to increase the number of female footballers, and on the other hand, it is crucial to decrease the number of girls quitting football prematurely. OBJECTIVE: To find the reasons for sports career termination among female football players. DESIGN: Cross-sectional with retrospective information about reasons of career termination. SETTING: Online questionnaire was filled out by online access. PARTICIPANTS: Ninety-three former female footballers. MAIN OUTCOME MEASURES: Factors leading to career termination. METHODS: Participants completed the online questionnaire. The analysis was performed referring to 2 groups: "injury group"-in which the injury was the main reason for quitting football, and "other group"-in which the female player stopped playing football due to all other factors. RESULTS: Thirty percent of former Polish female football players terminated their career due to a long-term treatment for an injury. Over 27% (27.7%) females had ended their careers because they were not able to reconcile sports with work/studying. Over 10% (10.8%) of former football players reported that becoming a wife and/or mother was the reason for career termination. Losing motivation and interest in the sport was reported by 9.2% (n = 6) of present study participants who decided to terminate the career due to noninjury reasons. CONCLUSIONS: The results clearly show that more effort is needed to support female football players, especially after an injury, so that they do not quit the sport voluntarily.

Prevalence of incorrect body posture in children and adolescents with overweight and obesity.

The ever increasing epidemics of overweight and obesity in school children may be one of the reasons of the growing numbers of children with incorrect body posture. The purpose of the study was the assessment of the prevalence of incorrect body posture in children and adolescents with overweight and obesity in Poznan, Poland. The population subject to study consisted of 2732 boys and girls aged 3-18 with obesity, overweight, and standard body mass. The assessment of body mass was performed based on BMI, adopting Cole's cutoff values. The evaluation of body posture was performed according to the postural error chart based on criteria complied by professor Dega. The prevalence rates of postural errors were significantly higher among children and adolescents with overweight and obesity than among the group with standard body mass. In the overweight group, it amounted to 69.2% and in the obese group to 78.6%. CONCLUSION:  The most common postural deviations in obese children and adolescents were valgus knees and flat feet. Overweight and obesity in children and adolescents, predisposing to higher incidence of some types of postural errors, call for prevention programs addressing both health problems. What is Known: • The increase in the prevalence of overweight and obesity among children and adolescents has drawn attention to additional health complications which may occur in this population such as occurrence of incorrect body posture. What is New: • The modified chart of postural errors proved to be an effective tool in the assessment of incorrect body posture. • This chart may be used in the assessment of posture during screening tests and prevention actions at school.

Braces for idiopathic scoliosis in adolescents.

BACKGROUND: Idiopathic scoliosis is a three-dimensional deformity of the spine. The most common form is diagnosed in adolescence. While adolescent idiopathic scoliosis (AIS) can progress during growth and cause a surface deformity, it is usually not symptomatic. However, in adulthood, if the final spinal curvature surpasses a certain critical threshold, the risk of health problems and curve progression is increased. OBJECTIVES: To evaluate the efficacy of bracing for adolescents with AIS versus no treatment or other treatments, on quality of life, disability, pulmonary disorders, progression of the curve, and psychological and cosmetic issues. SEARCH METHODS: We searched CENTRAL, MEDLINE, EMBASE, five other databases, and two trials registers up to February 2015 for relevant clinical trials. We also checked the reference lists of relevant articles and conducted an extensive handsearch of grey literature. SELECTION CRITERIA: Randomized controlled trials (RCTs) and prospective controlled cohort studies comparing braces with no treatment, other treatment, surgery, and different types of braces for adolescent with AIS. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by The Cochrane Collaboration. MAIN RESULTS: We included seven studies (662 participants). Five were planned as RCTs and two as prospective controlled trials. One RCT failed completely, another was continued as an observational study, reporting also the results of the participants that had been randomized.There was very low quality evidence from one small RCT (111 participants) that quality of life (QoL) during treatment did not differ significantly between rigid bracing and observation (mean difference (MD) -2.10, 95% confidence interval (CI) -7.69 to 3.49). There was very low quality evidence from a subgroup of 77 adolescents from one prospective cohort study showing that QoL, back pain, psychological, and cosmetic issues did not differ significantly between rigid bracing and observation in the long term (16 years).Results of the secondary outcomes showed that there was low quality evidence that rigid bracing compared with observation significantly increased the success rate in 20° to 40° curves at two years' follow-up (one RCT, 116 participants; risk ratio (RR) 1.79, 95% CI 1.29 to 2.50). There was low quality evidence that elastic bracing increased the success rate in 15° to 30° curves at three years' follow-up (one RCT, 47 participants; RR 1.88, 95% CI 1.11 to 3.20).There is very low quality evidence from two prospective cohort studies with a control group that rigid bracing increases the success rate (curves not evolving to 50° or above) at two years' follow-up (one study, 242 participants; RR 1.50, 95% CI 1.19 to 1.89) and at three years' follow-up (one study, 240 participants; RR 1.75, 95% CI 1.42 to 2.16). There was very low quality evidence from a prospective cohort study (57 participants) that very rigid bracing increased the success rate (no progression of 5° or more, fusion, or waiting list for fusion) in adolescents with high degree curves (above 45°) (one study, 57 adolescents; RR 1.79, 95% CI 1.04 to 3.07 in the intention-to-treat (ITT) analysis).There was low quality evidence from one RCT that a rigid brace was more successful than an elastic brace at curbing curve progression when measured in Cobb degrees in low degree curves (20° to 30°), with no significant differences between the two groups in the subjective perception of daily difficulties associated with wearing the brace (43 girls; risk of success at four years' follow-up: RR 1.40, 1.03 to 1.89). Finally, there was very low quality evidence from one RCT (12 participants) that a rigid brace with a pad pressure control system is no better than a standard brace in reducing the risk of progression.Only one prospective cohort study (236 participants) assessed adverse events: neither the percentage of adolescents with any adverse event (RR 1.27, 95% CI 0.96 to 1.67) nor the percentage of adolescents reporting back pain, the most common adverse event, were different between the groups (RR 0.72, 95% CI 0.47 to 1.10). AUTHORS' CONCLUSIONS: Due to the important clinical differences among the studies, it was not possible to perform a meta-analysis. Two studies showed that bracing did not change QoL during treatment (low quality), and QoL, back pain, and psychological and cosmetic issues in the long term (16 years) (very low quality). All included papers consistently showed that bracing prevented curve progression (secondary outcome). However, due to the strength of evidence (from low to very low quality), further research is very likely to have an impact on our confidence in the estimate of effect. The high rate of failure of RCTs demonstrates the huge difficulties in performing RCTs in a field where parents reject randomization of their children. This challenge may prevent us from seeing increases in the quality of the evidence over time. Other designs need to be implemented and included in future reviews, including 'expertise-based' trials, prospective controlled cohort studies, prospective studies conducted according to pre-defined criteria such as the Scoliosis Research Society (SRS) and the international Society on Scoliosis Orthopedic and Rehabilitation Treatment (SOSORT) criteria. Future studies should increase their focus on participant outcomes, adverse effects, methods to increase compliance, and usefulness of physiotherapeutic scoliosis specific exercises added to bracing.

Comparison of radiographic sagittal spinopelvic alignment between skeletally immature and skeletally mature individuals with Scheuermann's disease.

PURPOSE: The aim of this study was to compare radiographic sagittal spinopelvic parameters between skeletally immature and skeletally mature patients with Scheuermann's disease (SD). METHODS: Cross-sectional analysis of standing postero-anterior and lateral radiographs of the spine of patients with SD was performed. Sagittal vertical axis (SVA), thoracic kyphosis (TK), thoracolumbar kyphosis (TLK), lumbar lordosis (LL), pelvic incidence (PI), pelvic tilt (PT), and sacral slope (SS) were measured on the lateral radiographs. Risser's sign was assessed on the postero-anterior radiographs. All of the parameters measured were compared between skeletally immature (Risser's sign 0-3) versus mature patients (Risser's sign 5). PI, PT, and SS in both groups were compared to PI, PT, and SS reported for normal children, adolescents, and adults. RESULTS: Sixty-six patients with SD (33 immature and 33 mature) were retrospectively reviewed and included in the study. There was no significant difference between the two groups of SD patients in: SVA (-16.6 vs. -22.9 mm, p = 0.74), TK (57.8° vs. 56°, p = 0.66), TLK (7.8° vs. 11.7º, p = 0.14), LL (63.2° vs. 62.2°, p = 0.74), PI (36.7° vs. 39.4°, p = 0.20), PT (3.8° vs. 7.3°, p = 0.10), and SS (32.8° vs. 32.1°, p = 0.75). Both, the immature and mature group of SD patients presented significantly lower PI and SS than normal children, adolescents, and adults, and significantly lower PT than normal adults. CONCLUSIONS: There is no significant difference in sagittal spinopelvic parameters between skeletally immature and mature subjects with SD. Pelvic incidence in both groups of SD patients was significantly lower than PI in normal children, adolescents, and adults. This challenges the role of PI in predicting desired LL in patients with SD.

Calculation of corrected body height in idiopathic scoliosis: comparison of four methods.

PURPOSE: The aim of the study was to analyze four radiographic methods of calculating the loss of body height associated with scoliosis. METHODS: Thirty patients with right thoracic idiopathic scoliosis were examined with standing postero-anterior radiographs. Cobb angles of the upper thoracic, main thoracic and lumbar curves were measured. The loss of body height due to scoliosis was measured directly on the radiographs and then calculated using the methods of Bjure, Kono, Stokes and Ylikoski, respectively. The reproducibility of calculations was tested. Detailed analysis of two patients with similar Cobb angle but different trunk height was performed. RESULTS: The mean Cobb angle of the main thoracic curve was 46° (21°-74°). The mean loss of body height was 23 mm (11-43 mm) calculated by method of Bjure, 7 mm (-24 to 46 mm) by Kono, 20 mm (5-47 mm) by Stokes, 14 mm (3-36 mm) by Ylikoski, versus 18 mm (3-50 mm) measured directly on radiographs. The overall difference between the loss of body heights was significant (p < 0.0001), with significant differences in pairs for: Bjure versus Kono (p < 0.0001), Stokes versus Kono (p = 0.0002), Kono versus measured (p = 0.0061) and Bjure versus Ylikoski (p = 0.0386). Strong linear correlation between the methods was found (r ≥ 0.92; p < 0.0001). High reproducibility of height loss calculations was noticed. The two patients with similar Cobb angle and different trunk height revealed similar height loss calculated, while different loss measured on radiographs. CONCLUSIONS: There existed no overall agreement between the four methods of calculation of the loss of body height associated with scoliosis. Calculations based on the Cobb angle produced inaccuracy and could be supplemented with data considering trunk size.

Estrogen receptors genes polymorphisms and age at menarche in idiopathic scoliosis.

BACKGROUND: The age at menarche (AAM) is commonly in use in patients with IS as one of the maturity indicator suggesting deceleration of the growth velocity. The AAM was suggested to be related to predisposition and curve progression potential of IS. The late age at menarche was reported to be associated with higher prevalence of adolescent idiopathic scoliosis. The age at menarche is determined by both genetic and environmental factors as well as their interactions. Estrogen receptors 1 and 2 polymorphism were reported to be associated with AAM: in ESR1 XbaI and PvuII site polymorphism and in ESR2 AluI site polymorphism.The purpose of the study was to investigate associations of the ESR1 and ESR2 polymorphisms with AAM in IS patients and to evaluate association of AAM with IS severity. METHODS: 208 females with IS Caucasian females from Central Europe underwent clinical, radiological and genetic examinations. Four SNPs were selected XbaI (A/Grs9340799) and PvuII (C/T rs2234693) in ESR1and AluI (A/G rs4986938) and RasI (A/G rs1256049) in ESR2. Samples were analyzed with polymerase chain reaction followed by restriction fragments length polymorphism analysis (PCR-RFLP). The age of a menarche was established during personal interview with the patients and in case of children with their parents. The Cobb angle was measured. RESULTS: All genotypes followed HWE. Mean AAM for patients was 154.8 ± 14.7 months (12.9 ± 1.2 years). The earliest AAM was 121 and latest 192 months. There was no statistically significant difference between AAM mean values in each genotype, for the XbaI, PvuII, AluI and RsaI site polymorphisms the p values were p=0.7141, p=0.9774, p=0.7973 and p=0.2282, respectively. Patients divided according to Cobb into mild (<30°), moderate (30°-49°) or severe (≥ 50°) IS revealed tendency to delay AAM: 151.9 ± 14.7; 155.2 ± 14.8 and 157.9 ± 14.0 months, respectively. There was statistical significant difference between patients with mild <30° and severe ≥ 50° IS, p=0.0267. CONCLUSIONS: In IS patients estrogen receptors polymorphisms did not show association with the AAM. Patients with severe IS form revealed delayed AAM than patients with mild IS form.

Deep tissue massage and nonsteroidal anti-inflammatory drugs for low back pain: a prospective randomized trial.

OBJECTIVE: To investigate whether chronic low back pain therapy with deep tissue massage (DTM) gives similar results to combined therapy consisting of DTM and non-steroid anti-inflammatory drugs (NSAID). DESIGN: Prospective controlled randomized single blinded trial. SETTINGS: Ambulatory care of rehabilitation. PARTICIPANTS: 59 patients, age 51.8 ± 9.0 years, with chronic low back pain. Interventions. 2 weeks of DTM in the treatment group (TG) versus 2 weeks of DTM combined with NSAID in the control group (CG). MAIN OUTCOME MEASURES: Visual analogue scale, Oswestry disability index (ODI), and Roland-Morris questionnaire (RM). RESULTS: In both the TG and the CG, a significant pain reduction and function improvement were observed. VAS decreased from 58.3 ± 18.2 to 42.2 ± 21.1 (TG) and from 51.8 ± 18.8 to 30.6 ± 21.9 (CG). RM value decreased from 9.8 ± 5.1 to 6.4 ± 4.4 (TG), and from 9.3 ± 5.5 to 6.1 ± 4.6 (CG). ODI value decreased from 29.2 ± 17.3 to 21.4 ± 15.1 (TG) and from 21.4 ± 9.4 to 16.6 ± 9.4 (CG). All pre-post-treatment differences were significant; however, there was no significant difference between the TG and the CG. CONCLUSION: DTM had a positive effect on reducing pain in patients with chronic low back pain. Concurrent use of DTM and NSAID contributed to low back pain reduction in a similar degree that the DTM did.

Mental health of adults treated in adolescence with scoliosis-specific exercise program or observed for idiopathic scoliosis.

OBJECTIVE: To examine general mental health in adult males and females, who in adolescence participated in a scoliosis-specific therapeutic exercise program or were under observation due to diagnosis of scoliosis. DESIGN: Registry-based, cross-sectional study with retrospective data collection. METHODS: Sixty-eight subjects (43 women) aged 30.10 (25-39) years, with mild or moderate scoliosis (11-36° Cobb angle), and 76 (38 women) nonscoliotic subjects, aged 30.11 (24-38) years, participated. The time period since the end of the exercise or observation regimes was 16.5 (12-26) years. Beck Depression Inventory (BDI) and General Health Questionnaire (GHQ-28) scores were analyzed with the χ(2) and U tests. Multiple regression analyses for confounders were also performed. RESULTS: Intergroup differences of demographic characteristics were nonsignificant. Scoliosis, gender, participation in the exercise program, employment, and marital status were associated with BDI scores. The presence of scoliosis and participation in the exercise program manifested association with the symptoms. Higher GHQ-28 "somatic symptoms" subscale scores interacted with the education level. CONCLUSIONS: Our findings correspond to the reports of a negative impact of the diagnosis of scoliosis and treatment on mental health. The decision to introduce a therapeutic program in children with mild deformities should be made with judgment of potential benefits, risks, and harm.

Scoliosis Research Society (SRS) Criteria and Society of Scoliosis Orthopaedic and Rehabilitation Treatment (SOSORT) 2008 Guidelines in Non-Operative Treatment of Idiopathic Scoliosis.

According to the Scoliosis Research Society (SRS), idiopathic scoliosis (IS) is a curvature of more than 10° Cobb angle, affecting 2-3% of pediatric population. Idiopathic scoliosis accounts for 80% of all scoliosis cases. Non-operative principles in the therapy of idiopathic scoliosis, including Scoliosis Research Society (SRS) criteria and guidelines proposed by the experts of the Society on Scoliosis Orthopedic and Rehabilitation Treatment (SOSORTS) were presented. The possibility to carry out quality of life assessments in a conservative procedure was also demonstrated. Based on the natural history of idiopathic scoliosis, SRS criteria, SOSORT 2008 experts' opinion and the knowledge of the possibilities of psychological assessment of conservative IS treatment, rules were proposed regarding nonsurgical IS therapy procedures, with special consideration being paid to the proper treatment start time (age, Risser test, biological maturity, Cobb angle), possibility of curvature progression, the importance of physiotherapy and psychological assessment. The knowledge of SRS criteria and SOSORT guidelines regarding the conservative treatment of IS are essential for proper treatment (the right time to start treatment), and supports establishment of interdisciplinary treatment teams, consisting of a physician, a physiotherapist, an orthopedic technician and a psychologist.

Hip Joint Stability during and after Femoral Lengthening in Congenital Femoral Deficiency.

BACKGROUND: Hip stability remains a major preoccupation during femoral lengthening in Congenital Femoral Deficiency (CFD). We aimed to review hip stability in Paley type 1a CFD patients undergoing femoral lengthening. METHODS: A total of 33 patients with unilateral CFD, who were treated between 2014 and 2023, were retrospectively reviewed. In 20/33 cases (60.6%) the SUPERhip preparatory surgery was performed at a mean age of 4.3 years (range 2.7-8.1). The femoral lengthening using an external fixator was performed at a mean age of 7.8 years (range 4.3-14.3). RESULTS: All patients presented with a stable hip joint after preparatory surgery and during femoral lengthening. Six cases of hip instability at a mean of 637 days after the external fixator removal were observed (range 127 to 1447 days). No significant differences between stable and unstable hips were noted for (1) Center-Edge Angle: 23.7 vs. 26.1 deg; (2) Acetabular Inclination: 12.8 vs. 11.7 deg; and (3) Ex-Fix Index: 35.6 days/cm vs. 42.4 days/cm; p > 0.05. Late hip instability was related to Coxa Vara and decreased femoral antetorsion before lengthening. CONCLUSIONS: Late hip joint instability in Paley type 1a CFD patients may occur long after femoral lengthening despite hip morphology appearing to be normal on radiograms before and at the end of femoral lengthening. Coxa Vara, femoral torsional deformity, and posterior acetabular deficiency might be risk factors for hip instability.

"Real-Time Neuromonitoring" Increases the Safety and Non-Invasiveness and Shortens the Duration of Idiopathic Scoliosis Surgery.

Introduction: A practical solution to the incidental unreliability of intraoperative neuromonitoring (IONM) may be the simultaneous neurophysiological recording and control of the surgical field through a camera (the concept of "Real-time" IONM). During "Real-time" IONM, the surgeon is immediately warned about the possibility of damage to the neural structures during, but not after, standard idiopathic scoliosis (IS) corrective surgery procedures (the concept of "Surgeon-neurophysiologist" interactive, verbal IONM). This study aimed to compare the advantages, utilities, reliabilities, and time consumption of the two IONM scenarios. Methods: Studies were performed in two similar groups of patients undergoing surgery primarily due to Lenke 2 idiopathic scoliosis (N = 120), when both IONM approaches were applied. Neurophysiological evaluations of the spinal transmission were performed pre- (T0), intra- (before (T1) and after (T2) surgery), and postoperatively (T3), as well as once in healthy volunteers (control, N = 60). Non-invasive and innovative recordings of the motor evoked potentials (MEPs) bilaterally from the peroneal (PER) nerve and tibialis anterior (TA) muscle were performed with surface electrodes as a result of transcranial magnetic stimulation (TMS) or electrical stimulation (TES) at T0-T3. Results: In both groups, the MEP amplitudes and latencies recorded from the PER nerve were approximately 67% lower and 3.1 ms shorter than those recorded from the TA muscle. The MEP recording parameters differed similarly at T0-T3 compared to the control group. In all patients, the MEP parameters induced by TMS (T0) and TES (T1) did not differ. The MEP amplitude parameters recorded from the TA and PER at T1 and T2 indicated a bilateral improvement in the neural spinal conduction due to the surgical intervention. The TMS-induced MEP amplitude at T3 further increased bilaterally. In both IONM groups, an average 51.8 BIS level of anesthesia did not affect the variability in the MEP amplitude, especially in the PER recordings when the applied TES strength was 98.2 mA. The number of fluctuations in the MEP parameters was closely related to the number of warnings from the neurophysiologist during the transpedicular screw implantation, corrective rod implantation, and distraction, derotation, and compression procedures, and it was higher in the "Surgeon-neurophysiologist" IONM group. The average duration of surgery was shorter by approximately one hour in the "Real-time" IONM group. The number of two-way communications between the surgeon and the neurophysiologist and vice versa in the "Real-time" IONM group decreased by approximately half. Conclusions: This study proves the superiority of using "Real-time" IONM over the standard "Surgeon-neurophysiologist" IONM procedure in increasing the safety and non-invasiveness, shortening the time, and lowering the costs of the surgical treatment of IS patients. The modifications of the MEP nerve-conduction-recording technology with surface electrodes from nerves enable precise and reliable information on the pediatric patient's neurological condition at every stage of the applied surgical procedures, even under conditions of slight fluctuations in anesthesia.

Complications and Health-Related Quality of Life in Children with Various Etiologies of Early-Onset Scoliosis Treated with Magnetically Controlled Growing Rods-A Multicenter Study.

Background: Early-onset scoliosis (EOS) refers to spinal deformities that develop and are diagnosed before the age of 10. The most important goals of the surgical treatment of EOS are to stop the progression of curvature, achieve the best possible correction, preserve motion, and facilitate spinal growth. The objectives of this multicenter study were to analyze the risk of complications among patients with EOS treated using magnetically controlled growing rods (MCGRs) and assess the patients' and their parents' quality of life after diagnosis and treatment with a minimum two-year follow-up. Methods: Patients given an ineffective nonoperative treatment qualified for surgery with MCGRs. This study involved 161 patients (90 females and 71 males) who were classified according to the etiology of curvature. The intraoperative and postoperative complications and those that occurred during the continuation of treatment with MCGRs were recorded and analyzed. The 24-item Early-Onset Scoliosis Questionnaire (EOSQ-24) was used to evaluate the patients' quality of life and satisfaction with the treatment. Results: Implant-related complications requiring instrumentation revision were recorded in 26% of the patients. Medical complications occurred in 45% of the population. The EOSQ-24 revealed a significant improvement in the average scores during the follow-up. Conclusions: The treatment of early-onset scoliosis with MCGRs carries 66% risks of incurring medical and mechanical complications, the latter 26% of patients requiring revision procedures. Children with neuromuscular scoliosis, females, and with curvature greater than 90 degrees are at a higher risk of developing complications. Limiting the number of elective surgeries necessitated to prolong the instrumentation and treatment process for patients with MCGRs can greatly enhance their quality of life and satisfaction throughout the follow-up period.
