Validity and reliability of the adapted Dutch version of the Brace Questionnaire (BrQ).

The Brace Questionnaire (BrQ) is a disease-specific health-related quality of life (HRQOL) instrument for measuring perceived health status of scoliosis patients undergoing brace treatment. The purpose of this study is to evaluate the validity and reliability of a translated and culturally adapted Dutch version of the BrQ. The original Greek BrQ was translated into Dutch and a cross-cultural adaptation and validation processes were conducted. Subsequently, 80 adolescent idiopathic scoliosis (AIS) patients undergoing active brace treatment were included from 4 scoliosis centers to evaluate the validity and reliability of the Dutch version of the BrQ. The questionnaire's floor and ceiling effects, internal consistency, and test-retest reliability were assessed. Concurrent validity was evaluated by comparing the BrQ with the revised Scoliosis Research Society 22-item questionnaire (SRS-22r) scores. The mean total BrQ score was 75.9 (standard deviation [SD] 11.3) and the mean domain scores varied between 3.4 (SD 0.9) and 4.2 (SD 0.7) for the domains "vitality" and "bodily pain," respectively. There were no floor and ceiling effects for the total BrQ score. The BrQ showed satisfactory internal consistency in most subdomains with a Cronbach's α ranging between 0.35 for the domain "general health perception" and 0.89 for the domain "self-esteem and aesthetics." Excellent test-retest reproducibility was observed for the total BrQ score (ICC 0.91), and the BrQ was successfully validated against the SRS-22r. The translated and culturally adapted Dutch version of the BrQ is a valid and reliable HRQOL instrument for AIS patients undergoing brace treatment.

Is higher compliance to brace therapy associated with poorer quality of life and self-image? A 36-months follow-up study.

Brace treatment is the most effective tool for avoiding curve progression in moderate adolescent idiopathic scoliosis and high adherence is required to achieve therapeutic success. Despite this, the compliance often is impaired by the concern about the psychological well-being of adolescents. This 36-month follow-up study investigated if the patients most adherent to brace treatment could report a stronger impairment in the quality of life and body image. 64 adolescents with idiopathic scoliosis responded to the Scoliosis Research Society-22 revised Patient Questionnaire at 12, 24, and 36 months after prescription of a TLSO rigid brace. Retrospectively, participants who wore a brace for more than 75% of the prescribed time were assigned to the good-compliance group (GC); the others formed the poor-compliance group (PC). At 12 months the GC group showed higher scores in treatment satisfaction and at 36 months they did not differ from the PC group in the overall SRS-22r score. Moreover, they achieved a statistically significant improvement in the scoliosis severity, although they showed lower scores in the self-image domain. In our patient's cohort, increased brace adherence does not compromise QoL and provides better treatment outcomes. However, more attention is needed to maintain good self-perception.

Modeling of the chest wall response to prolonged bracing in pectus carinatum.

Pectus carinatum is a chest wall deformity that is often treated through the wearing of an external brace. The treatment of the deformity could benefit from a greater understanding of chest wall characteristics under prolonged loading. These characteristics are difficult to model directly but empirical studies can be used to create statistical models. 185 patients from 2018-2020 received bracing treatment. Data on the severity of the deformity, treatment pressures, and time of wear were recorded at the first fitting and all subsequent follow-up visits. This data was analyzed using a statistical mixed effects model to identify significant measures and trends in treatment. These models were designed to help quantify changes in chest wall characteristics through prolonged bracing. Two statistical models were created. The first model predicts the change in the amount of pressure to correct the deformity after bracing for a given time and pressure. The second model predicts the change in pressure response by the body on the brace after bracing for a given time and pressure. These models show a high significance in the amount of pressure and time to the changes in the chest wall response. Initial deformity severity is also significant in changes to the deformity. The statistical models predict general trends in pectus carinatum brace treatment and can assist in creating treatment plans, motivating patient compliance, and can inform the design of future treatment systems.

Study on the efficacy of brace therapy for developmental dysplasia of the hip with Graf IIc and greater severity.

To assess changes in the α and β angle with brace treatment in DDH classified as Type Graf IIc, D, III, and IV; to study the α angle threshold that can predict the treatment effect; to analyze the effective rate in different groups. A retrospective study was conducted on children from 2013 to 2018 with Graf type IIc and greater diagnosed with ultrasound (US). Brace therapy was applied to 356 patients, with 423 affected hips (Graf IIc: 202 hips; Graf D: 17 hips; Graf III: 118 hips; and Graf IV: 86 hips). For follow-up efficacy analyses using US, X-ray and clinical examination, based on the success of early treatment of the brace, the outcomes were divided into 'effective' and 'noneffective' groups. The statistical results showed that the α angle increased ( P < 0.05) and the β angle decreased ( P < 0.05). When α≥43°, the accuracy of success with early treatment was 95.95%. The overall effective rate of bracing treatment was 74.70%. Children with α ≥ 43° are recommended to receive brace therapy as soon as possible and demonstrate the best effects. The effective rate varies across different Graf types and the age at treatment initiation. Brace therapy is more effective for Graf IIc and D hips compared to Graf III and IV.

A comprehensive nonoperative treatment protocol for developmental dysplasia of the hip in infants.

Brace treatment is the cornerstone of managing developmental dysplasia of the hip (DDH), yet there is a lack of evidence-based treatment protocols, which results in wide variations in practice. To resolve this, we have developed a comprehensive nonoperative treatment protocol conforming to published consensus principles, with well-defined a priori criteria for inclusion and successful treatment. This was a single-centre, prospective, longitudinal cohort study of a consecutive series of infants with ultrasound-confirmed DDH who underwent a comprehensive nonoperative brace management protocol in a unified multidisciplinary clinic between January 2012 and December 2016 with five-year follow-up radiographs. The radiological outcomes were acetabular index-lateral edge (AI-L), acetabular index-sourcil (AI-S), centre-edge angle (CEA), acetabular depth ratio (ADR), International Hip Dysplasia Institute (IHDI) grade, and evidence of avascular necrosis (AVN). At five years, each hip was classified as normal (< 1 SD), borderline dysplastic (1 to 2 SDs), or dysplastic (> 2 SDs) based on validated radiological norm-referenced values. Of 993 infants assessed clinically and sonographically, 21% (212 infants, 354 abnormal hips) had DDH and were included. Of these, 95% (202 infants, 335 hips) successfully completed bracing, and 5% (ten infants, 19 hips) failed bracing due to irreducible hip(s). The success rate of bracing for unilateral dislocations was 88% (45/51 infants) and for bilateral dislocations 83% (20/24 infants). The femoral nerve palsy rate was 1% (2/212 infants). At five-year follow-up (mean 63 months (SD 5.9; 49 to 83)) the prevalence of residual dysplasia after successful brace treatment was 1.6% (5/312 hips). All hips were IHDI grade I and none had AVN. Four children (4/186; 2%) subsequently underwent surgery for residual dysplasia. Our comprehensive protocol for nonoperative treatment of infant DDH has shown high rates of success and extremely low rates of residual dysplasia at a mean age of five years.

Impact of Brace-Related Stress on Brace Compliance in Adolescent Idiopathic Scoliosis: A Single-Center Comparative Study Using Objective Compliance Measurement and Brace-Related Stress.

This study aimed to investigate the brace compliance and clinical background of patients with adolescent idiopathic scoliosis (AIS) who demonstrate different degrees of psychological brace-related stress. Forty-five patients initiating brace treatment with a Cobb angle between 25° and 45° were included. Patients receiving brace treatment for AIS were administered a questionnaire for brace-related stress (i.e., the Japanese version of the Bad Sobernheim Stress Questionnaire-Brace [JBSSQ-brace]). Based on their scores, we allocated the patients into two stress groups: mild-stress (≥16 points) and below-moderate-stress (<16 points). We investigated the character of brace compliance and brace-related psychological stress in all patients and compared the demographics and brace compliance between both groups. Forty-one of 45 patients completed the study. The mean JBSSQ-brace scores were 18.7±5.1, 19.1±5.2, and 18.7±5.0 points at the 1-month, 4-month, and 1-year follow-ups, respectively. There was no significant change in JBSSQ-brace scores over one year after the brace prescription (P=0.332). There was no difference in-brace compliance between seasons during the first month of brace prescription (P=0.252). Both groups' overall brace compliance was comparable (below-moderate: 17.1±7.1 h/day vs. mild: 20.4±3.0 h/day; P=0.078). The mild-stress group showed better compliance than the below-moderate-stress group on weekdays (below-moderate: 17.0±6.9 h/day vs. mild: 20.5±2.8 h/day; P=0.048) and at nighttime (below-moderate: 82.3%±27.0%/nighttime vs. mild: 93.8%±12.4%/nighttime; P=0.008). Overall, brace compliance was comparable among patients with different brace-related stress, but brace compliance during weekdays and nighttime was significantly better in the mild-stress group.

Psychosocial Effect of Brace Treatment in Adolescent Idiopathic Scoliosis: A Study Using EQ-5D.

Retrospective cohort study. To evaluate psychosocial effect of brace treatment in adolescent idiopathic scoliosis (AIS) using EuroQoL 5-dimension (EQ-5D) depression and anxiety category. AIS is a structural abnormality of the spine often affecting patients during the puberty, a critical period of developing psychosocial problems. Many questionnaires had been adapted to evaluate mental health and health-related quality of life of AIS patients. However, these questionnaires are often time consuming and difficult to obtain. Therefore, a simpler substitute-EQ-5D-was evaluated. This is a single-center retrospective cohort analysis of adult idiopathic scoliosis patients aged between 8 and 19, visiting outpatient's clinic. Beck's depression inventory, EQ-5D and EuroQoL visual assessment scale, and Objectified Body Consciousness Scale for Youth were compared between brace group and non-brace group of AIS patients. Furthermore, difference between male and female were evaluated within brace group. None of the questionnaire showed significant difference between brace and non-brace group. However, when male and female patients were compared within brace group, female patients were significantly more susceptible to depression and anxiety based on EQ-5D and body consciousness. Furthermore, depression and anxiety according to both BDI and EQ-5D were significantly correlated to health-related quality of life. During brace treatment of female AIS patients, psychosocial status played a significant role in health-related quality of life. EQ-5D is a simple way to monitor the mental health status.

Early brace treatment for idiopathic scoliosis may change the paradigm to improve curves.

This study evaluated whetherearly brace treatment of curves < 25° decreased theprevalence of curve progression and surgery. In a retrospective review, patients with idiopathic scoliosis Risser stages 0 to 2 braced at < 25° were followed until brace discontinuation, skeletal maturity, or surgery. Patients with predominantly primary thoracolumbar/lumbar curves were prescribed nighttime braces (NTB) and thoracic curves were prescribed fulltime braces (FTB). Comparisons were made for TLSO type (NTB vs. FTB) and triradiate cartilage (TRC) status (open vs. closed) at brace prescription. 283 patients were included, 81% who were Risser stage 0 with curves averaging 21.8° ± 2.1° at brace prescription. The average curve change was 2.4° ± 11.2°. Curves improved ≥ 6° in 23% of patients. Patients who were not skeletally mature at brace discontinuation (n = 39) had lower Cobb angles (16.7° vs. 23.9°, p < 0.001), better curve improvement (-4.7° vs. 2.1°, p < 0.001), and were braced for a shorter period of time (1.8years vs. 2.3years, p = 0.011) than those who were skeletally mature at brace discontinuation (n = 239). Only 7% of patients in NTB and 8% of patients in FTB with open TRC required surgery. The numbers needed to treat to prevent surgery in patients in FTB with open TRC was calculated to be 4. Early brace treatment (Cobb < 25° and open TRC) may not only reduce curve progression and the need for surgical treatment but may also result in curve improvement, thus challenging the paradigm that the goal of bracing is merely to stop curve progression. 3-retrospective cohort study.

Russian localization and validation of the BRACE QUESTIONNAIRE

BACKGROUND:According to the literature, the Greek questionnaire on the study of the quality of life of children and adolescents undergoing brace treatment (BRACE questionnaire, abbreviated as BrQ) is informative and reliable, which is confirmed by its validation in different countries. This necessitates the creation ofanadopted Russian version and its validation.&#x0D; AIM:To perform Russian localization and validation of the Greek questionnaire on the study of the quality of life of children and adolescents undergoing brace treatment.&#x0D; MATERIALS AND METHODS:Russian localization and validation of the Russian version of the questionnaire on braces (Ru-BrQ) was carried out in several stages: direct and reverse translations, examination of the questionnaire, formation ofapreliminary version, pilot testing of 104 patients with idiopathic scoliosis on brace treatment, development of the final version, reliability study using the evaluation of Cronbachs alpha criterion and intraclass correlation coefficient (ICC), and provision of the final version.&#x0D; RESULTS:According to the indicators of the overall Ru-BrQ score, 0% of patients scored at the floor and ceiling levels. The average quality of life scores according to Ru-BrQ and in the retest were 72 9.2 and 72.4 9.0 points, respectively. According to the ICC indicator, domains such as general health, self-esteem and aesthetics, vitality, and social functioning showed excellent reliability (0.9). Physical functioning and school activity demonstrated good reliability(0.750.9).Emotional functioning and body pain demonstrated moderate reliability (0.50.75). The Cronbachs alpha coefficient showed that except for the domains emotional functioning and body pain, where good internal consistency was determined (0.8), all other domains confirmed excellent internal consistency (0.9). The Pearson correlation coefficient (index 0.67) revealedanoticeable correlation between Ru-BrQ and the Russian version of SRS-22.&#x0D; CONCLUSIONS:The Russian version isareliable questionnaire for the study of the quality of life of children and adolescents undergoing brace treatment, comparable with the original Greek version of BrQ, and can be recommended for use in practical and scientific activities to assess the effect ofatorso brace on the quality of life in children and adolescents.

Evaluation of Humeral Shaft Fracture Outcomes by Treatment Method: A Systematic Review and Meta-analysis Based on Comparison Studies.

The purpose of this systematic review and meta-analysis was to evaluate various outcomes of humeral shaft fractures treated with different treatment methods, which included functional bracing, open reduction and internal fixation, intramedullary nailing, and locked compression plate. A systematic review was performed using research databases including PubMed, EMBASE, and Google Scholar. Keywords relating to treatment of humeral shaft fractures were used, and comparison studies that reported patient characteristics and outcomes, including nonunion, malunion, function scores, and complications, were included. One hundred fourteen records were screened, with 18 studies ultimately included in the meta-analysis. Treatment groups were consolidated into brace or surgery and then further categorized into subgroups based on surgical technique used. Postoperative events, complications, and functional scores were compared among the treatment groups. Statistical analysis for this study was conducted using Review Manager 5.3, with a standard p-value of ≤0.05 for statistical significance. Eighteen studies were included in this review with a total of 706 patients. Z-tests showed that risks of revision, nonunion, and malunion were higher in the brace treatment group compared with the surgical treatment group (p < 0.0001, <0.0001, 0.004, respectively). Risk of infection was expectedly higher in the surgical group compared with the brace group (p = 0.04). Radial nerve injury rates were also higher in the unspecified surgical group compared with the brace group (p = 0.01). In the surgical group, the mean Constant shoulder score was also significantly higher than that in the brace group (p = 0.004). When comparing the nail and plate groups, Z-tests revealed higher risks of delayed unions and other complications in the nail group (p = 0.04 and 0.001, respectively) but higher risk of infection in the plate group (p = 0.05). The conservative treatment of humeral shaft fractures with functional braces may be associated with a lower incidence of infection and nerve injury when compared with operative treatment methods. However, nonoperative treatment may also come with higher risks of revision, nonunion, and malunion than the many available surgical modalities. Operative management with either intramedullary nail or plate has shown to be a reliable method of management with reasonable outcomes for humeral shaft fractures. While the nail group had higher risk of delayed unions and other complications, the plate group had higher risk of infections. Both nail and plate surgical treatments have shown to result in high union rates and should be considered by the surgeon on a case-by-case basis when treating humeral shaft fractures. Level I.

Higher Baseline Serum Myokine of FSTL1 May Serve as a Potential Predictive Biomarker for Successful Brace Treatment in Girls With Adolescent Idiopathic Scoliosis.

A retrospective case-control study. This study aimed to investigate whether myokine, which is related to exercise and muscle mass, could serve as a biomarker for predicting bracing outcomes. Several risk factors have been documented to be associated with bracing failure in patients with adolescent idiopathic scoliosis (AIS). However, serum biomarkers have not been extensively explored. Skeletally immature females with AIS, without previous histories of bracing or surgery, were included. Peripheral blood was collected at the time of the bracing prescription. Baseline serum concentrations of 8 myokines [apelin, fractalkine, brain-derived neurotrophic factor, erythropoietin, osteonectin, fatty-acid-binding protein 3, follistatin-like 1 (FSTL1), and musclin] were measured by multiplex assays. Patients were followed up until weaned from bracing and then designated as a "failure" (defined as Cobb angle progression >5°) or "success." A logistic regression analysis was performed that accounted for serum myokines and skeletal maturity. We included 117 patients, with 27 in the failure group. Patients in the failure group had lower initial Risser sign and lower baseline serum levels of myokines, including FSTL1 (2217.3 ± 617.0 vs . 1369.3 ± 704.9, P = 0.002), apelin [116.5 (12.0, 335.9) vs . 83.5 (10.5, 221.1), P = 0.016], fractalkine (979.6 ± 457.8 vs . 743.8 ± 456.1, P = 0.020), and musclin [211.3 (16.3, 370.3) vs . 67.8 (15.5, 325.6), P = 0.049]. Following adjusted analysis, serum FSTL1 [odds ratio = 10.460; (2.213-49.453)] was determined to be predictive of bracing effectiveness. Patients who failed AIS bracing had significantly lower mean baseline levels of FSTL1 than those who achieved success. FSTL1 may serve as a biomarker that can inform outcomes after bracing.

Defining the Incidence of Residual Acetabular Dysplasia After Successful Reduction With a Harness

Background: The purpose of this study was to evaluate the rate of residual acetabular dysplasia (RAD), defined as an acetabular index (AI) of &gt;90th percentile of age and sex-matched controls, in a cohort of infants successfully treated with the Pavlik harness (PH). Methods: We retrospectively studied typically developing infants at a single center, with at least 1 dislocated hip, that was successfully treated with a PH and had a minimum of 48 months follow-up. Hip dislocation was defined as &lt;30% femoral head coverage at rest on pretreatment ultrasound or IHDI grade 3 or 4 on the pretreatment radiograph. Results: Forty-six dislocated hips (41 infants) were studied (4 males and 37 females). Brace treatment was initiated at an average age of 1.8 months (range: 2 d to 9.3 mo) and was maintained for an average of 10.2 months (range: 2.3 to 24.9 mo). All hips achieved IHDI grade 1 reduction. Five of 46 hips (11%) had an AI &gt;90th percentile at the conclusion of bracing. Average follow-up was 6.5 years (range: 4.0 to 15.2 y). We found a 30% incidence of RAD (14/46 hips) on final follow-up radiographs. Of these hips, 13/14 (93%) had AI &lt;90th percentile at the end of brace treatment. Comparing children with and without RAD, there were no differences in age at the initial visit or brace initiation, total follow-up, femoral head coverage at the initial visit, alpha angle at the initial visit, or total time in the brace (P &gt; 0.09). Conclusion: In a single-center cohort of infants with dislocated hips treated successfully with a PH, we observed a 30% incidence of RAD at a minimum 4.0-year follow-up. Normal acetabular morphology at the end of brace treatment did not result in normal acetabular morphology at the final follow-up in 13/41 hips (32%). We recommend that surgeons should pay close attention to the year-over-year change in both the AI and AI percentile. Level of Evidence: Level IV: case series.

The effect of brace on apical vertebral derotation in adolescent idiopathic scoliosis.

The current study aims to evaluate the effect of Boston brace treatment on apical vertebral derotation in adolescent idiopathic scoliosis (AIS) patients receiving conservative treatment. The study included 51 AIS patients, consisting of 8 males and 43 females, with Cobb angles between 25° and 45° and Risser's findings ranging from 0 to 4. The mean age of the participants was 12.20 ± 1.34years. All patients were treated with the Boston brace for a minimum of 2years and evaluated before the brace, during early brace use, and at the last follow-up. Radiographs were assessed to measure apical vertebral rotation (AVR) and vertebral translation (AVT). The SRS-22 questionnaire was used to evaluate patient outcomes. The radiographs of patients were evaluated over a mean follow-up period of 32.42 ± 8.65months. Before the brace, the mean AVR was 2.1 ± 0.6, while it was 1.1 ± 0.5 with the brace. At the last follow-up, the mean AVR was 1.3 ± 0.5 (p < 0.001). Before the brace, the mean AVT was 36.4 ± 9.6mm, which decreased to 16.7 ± 7.3mm with the brace (p < 0.001). At the last follow-up, the mean AVT was 19.8 ± 8.1mm (p < 0.001). The use of the brace had a significant corrective effect on thoracolumbar and lumbar curvatures compared to before the brace (p < 0.001). The findings of the current study suggest that the use of a Boston brace in the conservative treatment of AIS is effective in correcting the coronal and sagittal plane deformities, including thoracic, thoracolumbar, and lumbar curvatures, and in reducing apical vertebral rotation and translation.

Effectiveness of the Boston Brace in the Treatment of Paediatric Scoliosis: A Longitudinal Study from 2010-2020 in a National Spinal Centre.

Bracing can reduce curve progression in order to prevent or delay scoliosis surgery in growing children. Brace treatment is effective in adolescent idiopathic scoliosis (AIS), but there is less evidence of its efficacy in early-onset or non-idiopathic scoliosis. We assessed the outcome of bracing at the end point of treatment, including the patients' perception of clinical results. We reviewed 480 patients treated using Boston brace from 2010-2020 (70% female); 249 patients completed bracing (52%) and 118 patients (47.4%) did not require surgery, with 83% having idiopathic scoliosis. Brace success was considered scoliosis below 50° at the end of bracing, with the patient skeletally mature. A total of 131 patients required scoliosis surgery after bracing (64% had idiopathic scoliosis; adolescents 57% and juveniles 43%). All patients had a minimum two-year follow-up after bracing or after scoliosis correction, with the quality of life assessment questionnaires. A total of 98 out of 182 patients with idiopathic scoliosis did not require surgery (54%). Thoracic scoliosis improved with bracing by a mean of 3.4° and thoracolumbar/lumbar scoliosis by a mean of 6.8°. A total of 85 patients with AIS (64%) but only 9 patients with JIS (20%) did not need surgery. In the AIS group, 97 patients had scoliosis of 20-40°; 71 of these patients (73.2%) did not require scoliosis correction at the end of bracing. In total, 84 patients with idiopathic scoliosis had surgery at a mean of 14 years (surgery was delayed by a mean of 3.2 years). In total, 20 of 67 patients with non-idiopathic scoliosis did not need surgery (30%). Thoracic scoliosis improved with bracing by a mean of 8.4° and thoracolumbar/lumbar scoliosis by a mean of 0.8°. A total of 47 patients with non-idiopathic scoliosis required surgery at a mean of 13.1 years (surgery was delayed by a mean of 5.2 years). Multivariate regression analysis showed that idiopathic scoliosis, AIS, closed triradiate cartilage, post-menarche status, higher Risser grade and smaller scoliosis angle at initial presentation predicted brace success. Patients reported good function and self-image, reduced pain and high satisfaction after treatment in both the bracing-only and the bracing followed by surgery groups.

Are torso asymmetry and torso displacements in a computer brace model associated with initial in-brace correction in adolescent idiopathic scoliosis?

BackgroundLack of initial in-brace correction is strongly predictive for brace treatment failure in adolescent idiopathic scoliosis (AIS) patients. Computer-aided design (CAD) technology could be useful in quantifying the trunk in 3D and brace characteristics in order to further investigate the effect of brace modifications on initial in-brace correction and subsequently long-term brace treatment success. The purpose of this pilot study was to identify parameters obtained from 3D surface scans which influence the initial in-brace correction (IBC) in a Boston brace in patients with AIS.MethodsTwenty-fiveAIS patients receiving a CAD-based Boston brace were included in this pilot study consisting of 11 patients with Lenke classification type 1 and 14 with type 5 curves. The degree of torso asymmetry and segmental peak positive and negative torso displacements were analyzed with the use of patients’ 3D surface scans and brace models for potential correlations with IBC.ResultsThe mean IBC of the major curve on AP view was 15.9% (SD = 9.1%) for the Lenke type 1 curves, and 20.1% (SD = 13.9%) for the type 5 curves. The degree of torso asymmetry was weakly correlated with patient’s pre-brace major curve Cobb angle and negligible correlated with major curve IBC. Mostly weak or negligible correlations were observed between IBC and the twelve segmental peak displacements for both Lenke type 1 and 5 curves.ConclusionBased on the results of this pilot study, the degree of torso asymmetry and segmental peak torso displacements in the brace model alone are not clearly associated with IBC.

Comparative analysis of spinal stabilization techniques

Background: The purpose of this study was to compare different spinal stabilization techniques in terms of their effectiveness in providing stabilization and reducing pain. A systematic review was performed to identify relevant studies and analyze their findings. The studies were evaluated based on their methodological quality, sample size, and outcome measures. The results showed that the use of spinal bracing, spinal manipulation, and exercise-based treatments was found to be more effective than pharmacological interventions in providing spinal stabilization and reducing pain. The evidence suggests that a combination of these treatments may be more beneficial in providing adequate stabilization and reducing pain compared to a single intervention. Future research is needed to further explore the efficacy of different spinal stabilization techniques. Objective: The objective of this study was to compare and analyze the effectiveness of different spinal stabilization techniques in providing stabilization and reducing pain. Methodology: A systematic review was conducted department of orthopedic kth hospital Peshawar from jan 2020 to jan 2021 to identify relevant studies that evaluated the effectiveness of different spinal stabilization techniques in providing stabilization and reducing pain. The studies were evaluated based on their methodological quality, sample size, and outcome measures.

Patient Adherence to Wide Abduction Brace Treatment for Legg-Calvé-Perthes Disease.

A wide abduction brace called the A-frame brace is used to contain the deformed femoral head and improve femoral head remodeling in patients with Legg-Calvé-Perthes disease (LCPD). While there is some data showing the efficacy of brace treatment, little is known about patient adherence. The purpose of this study was to measure A-frame brace adherence using temperature sensors and to identify factors that influence adherence. This is an IRB-approved retrospective study of 61 patients with LCPD treated with an A-frame brace between ages 5 and 11. Brace wear was measured using built-in temperature sensors. Pearson correlation coefficient and multiple regression were used to determine relationships between patient characteristics and brace adherence. Of 61 patients, 80% were male. Mean age at LCPD onset was 5.9±1.8 years and the mean age at initiation of brace treatment was 7.1±1.5 years. Fifty-eight patients (95%) were in the fragmentation or reossification stage at the start of bracing, with 23 patients (38%) having lateral pillar B, 7 (11%) lateral pillar B/C, and 31 (51%) lateral pillar C. Forty-two (69%) patients were treated with a Petrie cast for 6 weeks before the A-frame brace. Mean adherence, defined as the ratio of measured over prescribed brace wear, was 0.69±0.32. Mean adherence improved with age ( P <0.05), increasing from 0.57 in patients less than 6 to 0.84 in patients aged 8 to 11. Patients first treated with a Petrie cast had significantly better adherence than those without (0.77 vs. 0.50; P <0.005). Adherence was negatively associated with the amount of prescribed brace wear per day ( P <0.005). Adherence did not change significantly between the start and end of treatment and was not significantly associated with sex or attention deficit hyperactivity disorder. A-frame brace adherence was significantly associated with age at treatment, prior Petrie casting, and the amount of daily prescribed brace wear. These findings provide new insight into A-frame brace treatment, which will lead to better patient selection and counseling to optimize adherence. III Therapeutic Study.

Cervicothoracic dislocation due to congenital and bone-dysplasia-related vertebral malformations.

To evaluate the approaches to treatment of congenital and bone-dysplasia-related pediatric cervicothoracic dislocations and define the optimal treatment method. The publications available in PubMed and Google Scholar data bases were selected following such criteria as the disease in question, pediatric age, the treatment description, and follow-up results. The paper also includes the descriptions of our own six cases of the cervicothoracic dislocations detected in children with different vertebral malformations. Only eight patients meeting the abovementioned selection criteria were found in the publications: three of them had the Klippel-Feil syndrome (KFS), two had one-level vertebral anomaly, one had neurofibromatosis (NF type 1), one had the Larsen syndrome, and one had a variation of VACTERL association. Their treatment was long term, multi stage, and complicated. Among six our own cases, four patients also had KFS, one had a variation of VACTERL association, and one had NF type 1. All the patients suffered from preoperative neurological disorders. Posterior instrumental fixation with posterior vertebral body resection was performed in four cases and one patient underwent a combined surgery. The parents of one of the patients refused the operation, so he was observed while receiving bracing treatment. Since the treatment was long term and complicated by reoperations, the average follow-up period comprised 5years. Congenital cervicothoracic dislocations are an extremely rare pathology that manifests itself in early age and requires an early surgical treatment. Failure to provide the treatment leads to the patient's disability. The surgical tactics for such patients is determined individually, but the published data and our own experience demonstrate that early multi-stage combined treatment has been the best option available so far. The cervicothoracic dislocations due to NF 1 manifest later and have a more favorable forecast.

Predictors of Clinically Meaningful Results of Bracing in a Large Cohort of Adolescents with Idiopathic Scoliosis Reaching the End of Conservative Treatment

We need good outcome predictors to maximize the treatment efficiency of adolescents with idiopathic scoliosis (AIS). The in-brace correction has shown an important predictive effect on brace failure, while the influence of other variables is still debated. We aimed to identify new outcome predictors from a big prospective database of AIS. Design: Retrospective analysis of prospectively collected data. AIS between 21 and 45°, Risser 0-2, brace prescription during the observation, treatment conclusion. All of the participants followed a personalized conservative approach according to the SOSORT Guidelines. End of growth below 30°-40°-50°. The regression model included age, BMI, Cobb angle, ATR, TRACE score, real brace wear (RBW), and in-brace correction (IBC). A total of 1050 patients, 84% females, ages 12.1 ± 1.1, 28.2 ± 7.9° Cobb. IBC increased by 30%, 24%, and 23% the odds of ending treatment below 30°, 40°, and 50°, respectively. The OR did not change after the covariate adjustment. Cobb angle and ATR at the start also showed a predictive effect. The systematic evaluation of IBC in clinics is useful for individuating the patient response to brace treatment more accurately, even in relation to the Cobb angle and ATR degrees at the start. Further studies are needed to increase the knowledge on predictors of AIS treatment results.

Finite element simulation of growth modulation during brace treatment of adolescent idiopathic scoliosis.

Adolescent idiopathic scoliosis (AIS) is a spine deformity whose progression during growth is affected by asymmetrical loads acting on the spine. The conservative brace treatment aims to limit the deformity's progression until the end of skeletal growth. This study's objective was to develop a patient-specific finite element model (FEM) simulating immediate in-brace correction and subsequent growth modulation over 2 years of treatment. Thirty-five retrospective AIS cases with documented correction over 2 years were analyzed. For each case, a patient-specific FEM was built, and in-brace correction was simulated. Vertebral growth and its modulation were modeled using simulated pressures on epiphyseal vertebral growth plates, including a compliance factor representing the recorded brace wear. The simulated Cobb angles, thoracic kyphosis, lumbar lordosis and apical vertebral rotation were compared with the actual measurements immediately in-brace and out-of-brace at the 2-year follow-up. Treatment outcomes according to simulated compliance scenarios of no brace-wear vs. full brace-wear were also computed. The average immediate in-brace difference between the simulated and actual Cobb angle was 4.9° (MT) and 3.7° (TL/L). 2-year out-of-brace, it was 5.6° (MT) and 5.4° (TL/L). The no brace-wear and full brace-wear compliance scenarios resulted respectively in 15/35 (43%) and 31/35 (89%) simulated spine deformities progressing by less than 5° over 2 years of treatment. Clinical significance: the FEM's ability to simulate the final correction with an accuracy on the order of the radiological measurements' interoperator reproducibility, combined with its sensitivity to brace-wear compliance, provides confidence in the model's predictions for a comparative context of use like improving a brace's design before its application.
