Translation, Transcultural Adaptation, and Validation of the Brazilian Portuguese Version of the Body Image Disturbance Questionnaire for Scoliosis (BR-BIDQ-S).

Objective The Body Image Disturbance Questionnaire for Scoliosis (BIDQ-S) for scoliosis derives from the Body Image Disturbance Questionnaire (BIDQ) with specific adaptation for scoliosis patients. Despite its significance and applicability, this instrument has never been translated into Brazilian Portuguese. The current study aimed to translate, transculturally adapt, and validate the BIDQ-S into Brazilian Portuguese. Methods BIDQ-S was translated and culturally adapted into Brazilian Portuguese using the American Association of Orthopedic Surgeons (AAOS) criteria. The questionnaire validation relied on internal consistency and comparison with the Cobb angle, Pediatric Quality of Life Inventory (PedsQL), and Scoliosis Research Society (SRS-22). The Brazilian version (BR-)BIDQ-S validation occurred in a sample of 35 adolescents with scoliosis waiting for specialized treatment. Results Internal consistency of the BR-BIDQ-S was 0.899 according to the Cronbach's index (i.e., virtually perfect). Although BR-BIDQ-S did not correlate with the Cobb angle, it presented correlations with the Physical, Emotional, and Social domains from the PedsQL and the Function/Activity domain from the SRS-22. Conclusion BR-BIDQ-S was reliable in evaluating the body image of adolescents with scoliosis, presenting an internal consistency of 0,899 (virtually perfect). Moreover, similar to the original instrument, it correlated with PedsQL and SRS-22.

Cross-cultural Validation of the Health Mindset Scale for Brazil.

Objective To cross-culturally validate the Health Mindset Scale for Brazil, as well as adapt the terms and questionnaires for adequate understanding of Brazilians, using factor analysis as an instrument to validate its reliability. Methods Cross-cultural validation of the Health Mindset Scale into Brazilian Portuguese using the Beaton method, Cronbach's alpha calculation and factor analysis Results The sample consisted of 215 patients aged between 18 and 87 years (M = 41.98; SD = 15.72), with a mean age between 31 and 50 years (42.0%), and female (52 .6%), a marginally significant difference (p < 0.10) between men and women was observed for item 3. In this item, men's mean (M = 5.48; SD = 0.99) was higher than the average for women (M = 5.10; SD = 1.22), with a small effect size for the difference (d = 0.26). Pearson's r correlation coefficient was examined between the mean score and age (r = -0.21; p = 0.002), the result of which indicated a weak, negative and significant linear relationship. The older the age, the lower the average score on the Health Mindset Scale. Conclusion The version of the health-focused mindset scale for Brazilian Portuguese was introduced and cross-culturally validated, demonstrating good reliability with a Cronbach's alpha of 0.786. Consequently, it constitutes a new instrument for clinical practice and can be correlated with established scales in the literature.

THORACOLOMBAR BURST FRACTURES: SHORT FIXATION, WITHOUT ARTHRODESIS AND WITHOUT REMOVAL OF THE IMPLANT.

Objectives: To present the functional outcomes, through the first case series in our country, of patients with thoracolumbar burst fractures (A3,A4), submitted to short posterior fixation, without arthrodesis and without removal of the implants, until the end of the minimum follow-up of one year. Methods: Fifty five patients consecutively treated between January/2010 and January/2019 were evaluated through medical records and imaging exams. Radiographic analysis was performed by mea suring local and segmental kyphosis using the Cobb method. Functional assessment was analyzed using the non-specific SF-36 questionnaire and the 1983 Denis pain and work-specific questionnaire, applied after 12 months of follow-up. Results: With a loss of five patients (9%), 22 (44%) patients reported having minimal and occasional pain and 8 (16%) patients reported having no pain. Three (6%) patients responded that they were completely incapacitated. Patients had a mean score of 73.16 points in the SF-36 domains. There was a significant reduction in kyphosis in 12 months (9.1±5.2 [min-max 0-22]) compared to the preoperative period (14.9±7.8 [min-max 0-32]) ( p≤0.01). One patient required implant removal due to the symptomatic prominence of the implant. Conclusion: This case series suggests that the technique leads to satisfactory functional results, without implant failure or significant kyphosis after a minimum follow-up of 12 months of treatment. Evidence Level IV; Case series.

Objetivo: Apresentar os desfechos funcionais, mediante primeira série de casos no nosso meio, de pacientes com fratura toracolombar do tipo explosão (A3, A4), submetidos a fixação posterior curta, sem artrodese e sem retirada dos implantes, até o final do acompanhamento mínimo de um ano. Métodos: Foram avaliados, por meio de prontuários e exames de imagem, 55 pacientes consecutivamente tratados entre Janeiro/2010 e Janeiro/2019. A análise radiográfica foi realizada medindo a cifose local e segmentar, pelo método de Cobb. A avaliação funcional analisada por meio do questionário inespecífico SF-36 e questionário específico de dor e trabalho de Denis de 1983, aplicados após os 12 meses de seguimento. Resultados: Com perda de cinco pacientes (9%), 22 (44%) pacientes relataram ter dor mínima e ocasional e 8 (16%) pacientes responderam não ter dor. Três (6%) pacientes responderam que estavam completamente incapacitados. Os pacientes tiveram uma pontuação média de 73,16 pontos nos domínios do SF-36. Houve redução significativa da cifose em 12 meses (9,1±5,2 [min-máx 0-22]) na comparação com o pré-operatório (14,9±7,8 [min-máx 0-32]) (p≤0,01). Um paciente necessitou de retirada do implante em razão da proeminência sintomática do implante. Conclusão: Esta série de casos sugere que a técnica leva a resultados funcionais satisfatórios, sem falha do implante ou cifose pós-traumática após acompanhamento mínimo de 12 meses de tratamento. Nível de Evidência IV; Série de casos.

The Relative Lymphocyte Count is Lower when the Etiological Agent in Pott Disease is Successfully Isolated.

Objective To describe the clinico-epidemiological, laboratory, and radiological characteristics of tuberculous spondylodiscitis in the Brazilian population, and to assess whether there are differences between patients in whom the etiological agent in Pott disease was isolated or not. Methods Patients diagnosed with tuberculosis (TB) of the spine (Pott disease) underwent follow-up between 2009 and 2019 at a quaternary hospital and were divided into 2 groups: successful isolation (SI) of the etiological agent (through bacilloscopy, culture, or positive molecular rapid test) and unsuccessful isolation (UI) of the etiological agent. Results From a total of 26 patients diagnosed with TB of the spine, 21 (80.7%) were male, with a mean age of 40 ± 22.5 years. The average lymphocyte counts were higher in the UI group (25.35 ± 13.08; p = 0.025) compared to the SI group (14.18 ± 7.48). Moreover, the monocyte/lymphocyte ratio was lower in the UI group (0.39 ± 0.22; p = 0.009) than in the SI group (0.89 ± 0.65). Relative lymphocyte counts higher than or equal to 16.7 had a sensitivity of 76.9% and specificity of 62.5% in the UI group. Values higher than or equal to 0.58 for the monocyte/lymphocyte ratio showed a sensitivity of 84.6% and specificity of 75.0% in the UI group. Conclusion No differences were observed regarding the clinico-epidemiological and radiological characteristics of the two experimental groups. However, the UI group had higher lymphocyte counts and a lower monocyte/lymphocyte ratio.

Spinal Cord Alignment in Patients with Thoracolumbar Burst Fracture.

Objective To evaluate the spinopelvic alignment in patients with thoracolumbar burst fracture (TBF) without neurological deficit treated nonsurgically and surgically in a tertiary reference trauma hospital. Method Retrospective cross-sectional study of patients with single level, type A3 and A4 AOSpine TBF only of the thoracolumbar region. Analysis of clinical data, low back pain (visual analogue scale [VAS]), Denis Pain Scale, quality of life (SF-36), sagittal (TC, TLC, LL, SVA) and spinopelvic (IP, PV, SI, PI-LL) radiographic parameters of patients treated surgically and nonsurgically. Results A total of 50 individuals with an average age of 50 years old with a mean follow-up of 109 months (minimum of 19 and maximum of 306 months) were evaluated. There was a significant difference between treatments for the Denis Work Scale ( p = 0.046) in favor of nonsurgical treatment. There was no significant difference between the treatments for lower back pain VAS and Denis Pain Scale ( p = 0.468 and p = 0.623). There was no significant difference between treatments in any of the domains evaluated with the SF-36 ( p > 0.05). Radiographic parameters were not different between the analyzed groups; however, all radiographic parameters showed significant difference between the population considered asymptomatic, except for pelvic incidence ( p < 0.005). Conclusions The spinopelvic alignment was normal in patients with TBF without neurological deficit treated nonsurgically and surgically after a minimum follow-up of 19 months. However, they presented a higher mean pelvic version and discrepancy between lumbar lordosis and pelvic incidence when compared with the reference values of the Brazilian population.

Time to surgery for adolescent idiopathic scoliosis: How long does it take? A multicenter study.

Study design: Retrospective review of multicentric data. Objectives: To estimate the time from initial visit to surgery in adolescent idiopathic scoliosis (AIS) patients and the main reasons for the time to surgery in a multicenter study. Methods: This retrospective study evaluated 509 patients with AIS from 16 hospitals across six Latin American countries. From each hospital's deformity registry, the following patient data were extracted: demographics, main curve Cobb angle, Lenke Classification at the initial visit and time of surgery, time from indication-for-surgery to surgery, curve progression, Risser skeletal-maturity score and causes for surgical cancelation or delay. Surgeons were asked if they needed to change the original surgical plan due to curve progression. Data also were collected on each hospital's waiting list numbers and mean delay to AIS surgery. Results: 66.8% of the patients waited over six months and 33.9% over a year. Waiting time was not impacted by the patient's age when surgery first became indicated (p = 0.22) but waiting time did differ between countries (p < 0.001) and hospitals (p < 0.001). Longer time to surgery was significantly associated with increasing magnitude of the Cobb angle through the second year of waiting (p < 0.001). Reported causes for delay were hospital-related (48.4%), economic (47.3%), and logistic (4.2%). Oddly, waiting time for surgery did not correlate with the hospital's reported waiting-list lengths (p = 0.57). Conclusion: Prolonged waits for AIS surgery are common in Latin America, with rare exceptions. At most centers, patients wait over six months, most commonly for economic and hospital-related reasons. Whether this directly impacts surgical outcomes in Latin America still must be studied.

Systematic Review of Platelet-Rich Plasma for Low Back Pain.

BACKGROUND: Low back pain (LBP) has a high economic burden and is strongly related to the degenerative process of the spine, especially in the intervertebral disc and of the facet joints. Numerous treatment modalities have been proposed for the management of LBP, and the use of platelet-rich plasma (PRP) has emerged as an innovative therapeutic option for degenerative disease of the spine. The present study aims to evaluate the efficacy of PRP injections in managing low back pain. METHODS: We conducted a systematic review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations, a registered at PROSPERO Systematic Reviews Platform, under number CRD42021268491. The PubMed, Web of Science, and Scopus databases were searched to identify relevant articles, along with hand searching to identify gray literature articles, with no language restrictions. Randomized clinical trials (RCTs), nonrandomized trials (NRTs), and case series (CSs) with more than 10 patients were considered eligible. The quality assessment and the risk of bias of the randomized clinical trials were evaluated using the RoB II tool. An evaluation of the description of the preparation methods was performed using an adapted version of the MIBO checklist. RESULTS: An electronic database search resulted in 2324 articles, and after the exclusion of noneligible articles, 13 RCTs and 27 NRTs or CSs were analyzed. Of the 13 RCTs, 11 found favorable results in comparison to the control group in pain and disability, one showed no superiority to the control group, and one was discontinued because of the lack of therapeutic effect at eight-week evaluation. Description of the PRP preparation techniques were found in almost all papers. The overall risk of bias was considered high in 2 papers and low in 11. An adapted MIBO checklist showed a 72.7% compliance rate in the selected areas. CONCLUSIONS: In this systematic review, we analyzed articles from English, Spanish and Russian language, from large databases and grey literature. PRP was in general an effective and safe treatment for degenerative LPB. Positive results were found in almost studies, a small number of adverse events were related, the risk of bias of the RCTs was low. Based on the evaluation of the included studies, we graded as level II the quality of the evidence supporting the use of PRP in LBP. Large-scale, multicenter RCTs are still needed to confirm these findings.

CORRELATION BETWEEN TYPES OF MINDSET AND QUALITY OF LIFE EVALUATION IN PATIENTS WITH SCOLIOSIS.

Scoliosis is a pathology with multiple etiologies that leads to aesthetic changes, increased morbidity and, especially, psychological damage. Objective: This work aims to compare two mindset types (fixed and growth) and assess levels of quality of life in individuals with scoliosis. Methods: Two questionnaires, Scoliosis Research Society-30 (SRS-30) and Early-Onset Scoliosis-24 Questionnaire (EOSQ-24), associated with the "Health Mindset Scale," were used. We applied the SRS-30 to patients who were independent or whose diagnosis of spinal deformity occurred after the age of 10 years. For patients diagnosed before the age of 10 or who presented dependence due to cognitive impairment, caregivers were subjected to the "Health Mindset Scale" and EOSQ-24 questionnaires. Results: The sample consisted of 35 patients aged from 4 to 46 years, the majority aged from 15 to 18 years old (42.9%), female (71.4%), and with neuromuscular scoliosis (28.6%). The only significant result (p = 0.060) was the increase in pain/discomfort scores in the EOSQ-24 for a patient with a growth mindset. Lastly, there was no statistical difference between groups, however, in patients with a growth mindset, there was a tendency (p = 0.060) to have a higher pain/discomfort score, assessed via the EOSQ-24 score, reported by the caregiver. Level of Evidence III, Retrospective Comparative Study.

A escoliose é uma patologia com múltiplas etiologias e que acarreta alterações estéticas, aumento de morbidade e principalmente danos psicológicos. Objetivo: Comparar dois tipos de mindset (fixo e construtivo) e o nível de qualidade de vida. Métodos: Foram utilizados dois questionários, o Scoliosis Research Society-30 (SRS-30) e o Early-Onset Scoliosis-24 Questionnaire (EOSQ-24), associados à escala Health Mindset Scale. Aplicamos o SRS-30 em pacientes independentes ou cujo diagnóstico de deformidade na coluna ocorreu após os 10 anos. Já no caso de pacientes com diagnóstico antes dos 10 anos ou que apresentassem dependência devido a dificuldades cognitivas, os cuidadores foram submetidos à Health Mindset Scale e ao EOSQ-24. Resultados: A amostra foi composta por 35 pacientes com idades entre 4 e 46 anos, sendo a maioria entre 15 e 18 anos (42,9%), do sexo feminino (71,4%) e com escoliose do tipo neuromuscular (28,6%). O único resultado com significância (p = 0,060) foi o aumento dos escores de dor/desconforto nos questionários EOSQ-24 em paciente com mindset de crescimento. Por fim, não houve diferença estatisticamente significante entre os grupos, porém, em pacientes com mindset construtivo, houve tendência (p = 0,060) de maior escore de dor/desconforto avaliado por meio do EOSQ-24 e referido pelo cuidador. Nível de Evidência III, Estudo Retrospectivo Comparativo.

Health-Related Predictive Factors of Brazilian Children With Early Onset Scoliosis Using the EOSQ-24 and CHQ-PF50 Questionnaires.

BACKGROUND: Assessing the quality of life (QOL) of children with early onset scoliosis (EOS) has been discussed recently. Therefore, the study aimed to apply and correlate the 24-item Early Onset Scoliosis Questionnaire (EOSQ-24) with the 50-item Childhood Health Questionnaire (CHQ-PF50) to find predictive factors impacting QOL. METHODS: Cross-sectional study involving a population of caregivers of patients with EOS. The sample consisted of 72 patients. Two research assistants applied the Portuguese version of the EOSQ-24 and CHQ-PF50 in 3 treatment centers. The EOSQ-24 assesses the subjective response of children with EOS from the parent's point of view. The CHQ is a self-administered questionnaire or parental proxy assessment of the psychological and social status of children aged 5 to 18 years. RESULTS: Of 72 patients, 41 (56.9%) were females, mean age of 11.9 ± 4.2 years. The most common scoliosis was of neuromuscular origin (32%). The CHQ-PF50 showed that family-related items had significant scores. The most affected subcategory was physical function (45.5), and the least affected was mental health (90.8). Thus, the CHQ-PF50 PhS summary index was 27, and the CHQ-PF50 PsS was 71.7. Moreover, the critical categories for the EOSQ-24 questionnaire were daily life and physical function (45.1 and 47.8, respectively), and the least affected categories were transfer and pulmonary function (70.8 and 68.9, respectively). Four subcategories showed a strong correlation between both questionnaires: general health (r = 0.749, P < 0.001), physical function (r = 0.645, P < 0.001), bodily pain (r = 0.714, P < 0.001), and mental health (r = 0.424, P < 0.001). Using CHQ-PF50 as a dependent variable in multiple regression analysis (P = 0.028), the only variable affecting the scores was syndromic scoliosis (P = 0.019; 95% CI -27.4 to -2.5). CONCLUSION: A strong correlation between both questionnaires was seen for general health, physical function, bodily pain, and mental health. Syndromic scoliosis was a predictor of worse QOL according to the CHQ-PF50.

Personalized Interventional Surgery of the Lumbar Spine: A Perspective on Minimally Invasive and Neuroendoscopic Decompression for Spinal Stenosis.

Pain generator-based lumbar spinal decompression surgery is the backbone of modern spine care. In contrast to traditional image-based medical necessity criteria for spinal surgery, assessing the severity of neural element encroachment, instability, and deformity, staged management of common painful degenerative lumbar spine conditions is likely to be more durable and cost-effective. Targeting validated pain generators can be accomplished with simplified decompression procedures associated with lower perioperative complications and long-term revision rates. In this perspective article, the authors summarize the current concepts of successful management of spinal stenosis patients with modern transforaminal endoscopic and translaminar minimally invasive spinal surgery techniques. They represent the consensus statements of 14 international surgeon societies, who have worked in collaborative teams in an open peer-review model based on a systematic review of the existing literature and grading the strength of its clinical evidence. The authors found that personalized clinical care protocols for lumbar spinal stenosis rooted in validated pain generators can successfully treat most patients with sciatica-type back and leg pain including those who fail to meet traditional image-based medical necessity criteria for surgery since nearly half of the surgically treated pain generators are not shown on the preoperative MRI scan. Common pain generators in the lumbar spine include (a) an inflamed disc, (b) an inflamed nerve, (c) a hypervascular scar, (d) a hypertrophied superior articular process (SAP) and ligamentum flavum, (e) a tender capsule, (f) an impacting facet margin, (g) a superior foraminal facet osteophyte and cyst, (h) a superior foraminal ligament impingement, (i) a hidden shoulder osteophyte. The position of the key opinion authors of the perspective article is that further clinical research will continue to validate pain generator-based treatment protocols for lumbar spinal stenosis. The endoscopic technology platform enables spine surgeons to directly visualize pain generators, forming the basis for more simplified targeted surgical pain management therapies. Limitations of this care model are dictated by appropriate patient selection and mastering the learning curve of modern MIS procedures. Decompensated deformity and instability will likely continue to be treated with open corrective surgery. Vertically integrated outpatient spine care programs are the most suitable setting for executing such pain generator-focused programs.

Spinal infections in children: a review.

Spondylodiscitis affects children aged between two and eight years, and mainly involves the lumbar or lumbosacral spine. Diagnosis is difficult because the symptoms are not very specific and due to the children's difficulty in communicating. Unlike adults, children have vascularised intervertebral discs, which explains the higher incidence of this disease in this age group. C-reactive protein, and blood and urine cultures are important laboratory tests. In most cases, fine needle or traditional biopsy helps identify the pathogen particularly in patients who do not respond to the antibiotic therapy test. Magnetic resonance imaging has high sensitivity and specificity in the investigation of pyogenic infection of the spine, particularly in the early stages, when these changes are not shown in other imaging tests. X-rays can take up to six weeks to show changes. The first radiographic sign of infection is the irregularity of the vertebral endplates in the infection area, followed by their erosion and that of the adjacent bone, decreased disc space, segmental collapse, loss of lordosis (in cases of low back involvement) and ultimately, permanent structural deformity. After eight to twelve weeks, local regeneration occurs, accompanied by bone sclerosis arising from the formation of new trabecular bone, replacing the necrotic cancellous bone. Effective treatment often leads to bone fusion of the affected disc space. However, when no therapy is adopted, total vertebral collapse can occur. The treatment involves immobilisation, antibiotic therapy, and surgical decompression in more advanced cases.

A Simple Double-Spin Closed Method for Preparing Platelet-Rich Plasma.

OBJECTIVE: To describe and analyze a new protocol for the extraction of platelet-rich plasma (PRP) for use in clinical practice and compare this technique with methods that have been previously described in the medical literature. METHODS: Sixteen blood samples from healthy volunteers were collected. PRP was prepared using our new double-spin technique, consisting of successive centrifugation of blood samples with two different spins, without opening the container. Descriptive analysis of cell counts in baseline and PRP samples was undertaken. Comparison between cell and platelet count in baseline and PRP samples, as well as the statistical analysis, were done. RESULTS: The mean platelet concentration ratio was 3.47 (SD: 0.85; 95% CI: 3.01-3.92; range: 2.48-5.71). The baseline whole blood platelet count correlated positively to the PRP platelet count (rP = 0.56; 95% CI: 0.09-0.88; P = 0.023). The PRP was enriched for lymphocytes and monocytes but presented significantly lower counts of neutrophils and eosinophils in comparison to baseline. CONCLUSION:  Results show a safe and easily reproducible method to obtain PRP for use in clinical daily practice.

Thoracolumbar Burst Fracture: McCormack Load-sharing Classification: Systematic Review and Single-arm Meta-analysis.

STUDY DESIGN: A systematic review and single-arm meta-analysis of randomized clinical trials. OBJECTIVE: The aim of this study was to evaluate whether the load-sharing classification (LSC) is reliable to predict the best surgical approach for thoracolumbar burst fracture (TBF). SUMMARY OF BACKGROUND DATA: There is no previous review evaluating the efficacy of the use of LSC as a guide in the surgical treatment of burst fractures. METHODS: On April 19th, 2019, a broad search was performed in the following databases: EMBASE, PubMed, Cochrane, SCOPUS, Web of Science, LILACS, and gray literature. This study was registered on the International Prospective Register of Systematic Reviews. We included clinical trials involving patients with TBF undergoing posterior surgical treatment, classified by load-sharing score, and that enabled the analysis of the outcomes loss of segmental kyphosis and implant failure (IF). We performed random- or fixed-effects models meta-analyses depending on the data homogeneity. Heterogeneity between studies was estimated by I2 and τ2 statistics. RESULTS: The search identified 189 references, out of which nine studies were eligible for this review. All articles presenting LSC up to 6 proved to be reliable in indicating that only posterior instrumentation is necessary, without screw failures or loss of kyphosis correction. For cases where the LSC was >6, only 2.5% of the individuals presented IF upon posterior approach alone. For loss of kyphosis correction, only 5% of patients had this outcome where LSC >6. For both outcomes together, we had 6% of postoperative problems (I2 = 77%, τ2 < 0.0015, P < 0.01). CONCLUSION: Load-sharing scores up to 6 are 100% reliable, only requiring posterior instrumentation for stabilization. For scores >6, the risk of implant breakage and loss of kyphosis correction in posterior fixation alone is low. Thus, other factors should be considered to define the best surgical approach to be adopted.Level of Evidence: 1.

Validation of the Brazilian Portuguese Version of the 24-Item Early-Onset Scoliosis Questionnaire.

STUDY DESIGN: Multicenter prospective study. OBJECTIVES: To validate the Early-Onset Scoliosis 24 Questionnaire (EOSQ-24) questionnaire for the Brazilian Portuguese language, a widely used tool for assessing the impact of different treatments and interventions in EOS patients. METHODS: The EOSQ-24 questionnaire was cross-culturally adapted following guidelines already published. After language adjustments by a group of experts, the final version of the Brazilian Portuguese EOSQ-24 was applied to a group of 76 patients (35 male and 41 female). Internal consistency was evaluated using the Cronbach α coefficient and item-total correlations. Continuous variables were recorded as median values and interquartile ranges and categorical variables as percentages. RESULTS: In the study group, 76 patients were evaluated. The total EOSQ-24 Cronbach α coefficient was 0.883, indicating excellent reliability. The internal consistency of EOSQ-24 was assessed in 3 domains: patient quality of Life, parental burden, and satisfaction (Cronbach α: 0.816-0.934). The range across all subdomains was 0.473 to 0.934. Floor effects for the 24 items were between 1.3% and 43.4% and ceiling effects, between 3.9% and 42.1%. CONCLUSIONS: The Brazilian Portuguese adaptation of the EOSQ-24 shows excellent reliability and can be a valid tool for psychometric assessment of children with EOS.

Reconstruction of the Lower Limb with Fasciocutaneous Flap of the Distal Pedicle - Modified Technique of Monteiro, Series of 15 Cases.

Objective To describe and demonstrate the outcomes of the modified Monteiro (1991) technique for lower limb reconstruction with a fasciocutaneous flap of the distal pedicle in a series of 15 cases. Method We present the technique and outcomes from a series of 15 cases of the modified technique using a fasciocutaneous flap of the distal pedicle to repair the lower third of the leg and the foot. Results Outcomes were satisfactory since these flaps provided good cutaneous and subcutaneous tissue coverage in cases with bone exposure and skin loss. The donor area was closed 3 days after surgery with a partial skin graft to provide better graft viability. Conclusion The fasciocutaneous flap of the distal pedicle proved to be a good option for reconstruction of the middle and lower thirds of the leg, offering good bone coverage.

Spinal Cord Alignment in Patients with Thoracolumbar Burst Fracture / Alinhamento espinopélvico em pacientes com fratura toracolombar explosão

Abstract Objective To evaluate the spinopelvic alignment in patients with thoracolumbar burst fracture (TBF) without neurological deficit treated nonsurgically and surgically in a tertiary reference trauma hospital. Method Retrospective cross-sectional study of patients with single level, type A3 and A4 AOSpine TBF only of the thoracolumbar region. Analysis of clinical data, low back pain (visual analogue scale [VAS]), Denis Pain Scale, quality of life (SF-36), sagittal (TC, TLC, LL, SVA) and spinopelvic (IP, PV, SI, PI-LL) radiographic parameters of patients treated surgically and nonsurgically. Results A total of 50 individuals with an average age of 50 years old with a mean follow-up of 109 months (minimum of 19 and maximum of 306 months) were evaluated. There was a significant difference between treatments for the Denis Work Scale (p= 0.046) in favor of nonsurgical treatment. There was no significant difference between the treatments for lower back pain VAS and Denis Pain Scale (p= 0.468 and p= 0.623). There was no significant difference between treatments in any of the domains evaluated with the SF-36 (p> 0.05). Radiographic parameters were not different between the analyzed groups; however, all radiographic parameters showed significant difference between the population considered asymptomatic, except for pelvic incidence (p< 0.005). Conclusions The spinopelvic alignment was normal in patients with TBF without neurological deficit treated nonsurgically and surgically after a minimum follow-up of 19 months. However, they presented a higher mean pelvic version and discrepancy between lumbar lordosis and pelvic incidence when compared with the reference values of the Brazilian population.

Resumo Objetivo Avaliar o alinhamento espinopélvico em pacientes com fratura toracolombar do tipo explosão (FTE) sem déficit neurológico tratados de forma não operatória e operatória em um hospital terciário de referência em trauma. Método Estudo transversal retrospectivo de pacientes com FTE apenas da região toracolombar, de nível único, do tipo A3 e A4 AOSpine. Análise de dados clínicos, dor lombar (escala visual analógica [EVA]), Escala de Denis, qualidade de vida (SF-36), parâmetros radiográficos sagitais (cifose torácica [CT], cifose toracolombar [CTL], lordose lombar [LL] e eixo vertical sagital [EVS]) e espinopélvicos (incidência pélvica [IP], versão pélvica [VP], inclinação sacral [IS] e a discrepância entre incidência pélvica e lordose lombar [IP-LL]) de pacientes tratados de forma operatória e não operatória. Resultados O presente estudo avaliou um total de 50 indivíduos com uma média de 50 anos de idade com acompanhamento médio de 109 meses (mínimo de 19 e máximo de 306 meses). Houve diferença significativa entre os tratamentos para Denis trabalho (p= 0,046) a favor do tratamento não operatório. Não houve diferença significativa entre os tratamentos para EVA dor lombar e Denis dor (p= 0,468 e p= 0,623). Não houve diferença significante entre os tratamentos em nenhum dos domínios avaliados do SF-36 (p> 0,05). Parâmetros radiográficos não se mostraram diferentes entre os grupos analisados; contudo, todos os parâmetros radiográficos mostraram diferença significante entre a população considerada assintomática, com exceção da incidência pélvica (p< 0,005). Conclusões O alinhamento espinopélvico foi normal em pacientes com FTE sem déficit neurológico tratados de forma não operatória e operatória, após acompanhamento mínimo de 19 meses. Entretanto, estes pacientes apresentaram maior média de versão pélvica e de discrepância entre lordose lombar e incidência pélvica quando comparados com os valores de referência da população brasileira.

The Relative Lymphocyte Count is Lower when the Etiological Agent in Pott Disease is Successfully Isolated / O número relativo de linfócitos é menor quando o agente etiológico da doença de Pott é isolado com sucesso

Abstract Objective To describe the clinico-epidemiological, laboratory, and radiological characteristics of tuberculous spondylodiscitis in the Brazilian population, and to assess whether there are differences between patients in whom the etiological agent in Pott disease was isolated or not. Methods Patients diagnosed with tuberculosis (TB) of the spine (Pott disease) underwent follow-up between 2009 and 2019 at a quaternary hospital and were divided into 2 groups: successful isolation (SI) of the etiological agent (through bacilloscopy, culture, or positive molecular rapid test) and unsuccessful isolation (UI) of the etiological agent. Results From a total of 26 patients diagnosed with TB of the spine, 21 (80.7%) were male, with a mean age of 40 ± 22.5 years. The average lymphocyte counts were higher in the UI group (25.35 ± 13.08; p= 0.025) compared to the SI group (14.18 ± 7.48). Moreover, the monocyte/lymphocyte ratio was lower in the UI group (0.39 ± 0.22; p= 0.009) than in the SI group (0.89 ± 0.65). Relative lymphocyte counts higher than or equal to 16.7 had a sensitivity of 76.9% and specificity of 62.5% in the UI group. Values higher than or equal to 0.58 for the monocyte/lymphocyte ratio showed a sensitivity of 84.6% and specificity of 75.0% in the UI group. Conclusion No differences were observed regarding the clinico-epidemiological and radiological characteristics of the two experimental groups. However, the UI group had higher lymphocyte counts and a lower monocyte/lymphocyte ratio.

Resumo Objetivo Descrever as características clínico-epidemiológicas, laboratoriais e radiológicas da espondilodiscite tuberculosa na população brasileira e avaliar se há diferenças entre pacientes em que o agente etiológico da doença de Pott foi isolado ou não. Métodos Os pacientes diagnosticados com tuberculose (TB) da coluna (doença de Pott) foram acompanhados em um hospital quaternário entre 2009 e 2019 e divididos em 2 grupos: isolamento positivo (IP) do agente etiológico (por baciloscopia, cultura ou teste rápido molecular positivo) e isolamento negativo (IN) do agente etiológico. Resultados De um total de 26 pacientes com diagnóstico de TB da coluna, 21 (80,7%) eram do sexo masculino, e a média de idade era de 40 ± 22,5 anos. As contagens médias de linfócitos foram maiores no grupo IN (25,35 ± 13,08; p= 0,025) do que no grupo IP (14,18 ± 7,48). Além disso, a relação monócito/linfócito foi menor no grupo IN (0,39 ± 0,22; p= 0,009) do que no grupo IP (0,89 ± 0,65). O número relativo de linfócitos maior ou igual a 16,7 teve sensibilidade de 76,9% e especificidade de 62,5% no grupo IN. A razão monócito/linfócito maior ou igual a 0,58 teve sensibilidade de 84,6% e especificidade de 75,0% no grupo IN. Conclusão Não observamos diferenças em relação às características clínico-epidemiológicas e radiológicas entre os dois grupos experimentais. No entanto, o grupo IN apresentou maior número de linfócitos e menor razão monócito/linfócito.

Thoracolombar burst fractures: short fixation, without arthrodesis and without removal of the implant / Fratura toracolombar explosão: fixação curta, sem artrodese e sem a retirada do implante

ABSTRACT Objectives: To present the functional outcomes, through the first case series in our country, of patients with thoracolumbar burst fractures (A3,A4), submitted to short posterior fixation, without arthrodesis and without removal of the implants, until the end of the minimum follow-up of one year. Methods: Fifty five patients consecutively treated between January/2010 and January/2019 were evaluated through medical records and imaging exams. Radiographic analysis was performed by mea suring local and segmental kyphosis using the Cobb method. Functional assessment was analyzed using the non-specific SF-36 questionnaire and the 1983 Denis pain and work-specific questionnaire, applied after 12 months of follow-up. Results: With a loss of five patients (9%), 22 (44%) patients reported having minimal and occasional pain and 8 (16%) patients reported having no pain. Three (6%) patients responded that they were completely incapacitated. Patients had a mean score of 73.16 points in the SF-36 domains. There was a significant reduction in kyphosis in 12 months (9.1±5.2 [min-max 0-22]) compared to the preoperative period (14.9±7.8 [min-max 0-32]) ( p≤0.01). One patient required implant removal due to the symptomatic prominence of the implant. Conclusion: This case series suggests that the technique leads to satisfactory functional results, without implant failure or significant kyphosis after a minimum follow-up of 12 months of treatment. Evidence Level IV; Case series.

RESUMO Objetivo: Apresentar os desfechos funcionais, mediante primeira série de casos no nosso meio, de pacientes com fratura toracolombar do tipo explosão (A3, A4), submetidos a fixação posterior curta, sem artrodese e sem retirada dos implantes, até o final do acompanhamento mínimo de um ano. Métodos: Foram avaliados, por meio de prontuários e exames de imagem, 55 pacientes consecutivamente tratados entre Janeiro/2010 e Janeiro/2019. A análise radiográfica foi realizada medindo a cifose local e segmentar, pelo método de Cobb. A avaliação funcional analisada por meio do questionário inespecífico SF-36 e questionário específico de dor e trabalho de Denis de 1983, aplicados após os 12 meses de seguimento. Resultados: Com perda de cinco pacientes (9%), 22 (44%) pacientes relataram ter dor mínima e ocasional e 8 (16%) pacientes responderam não ter dor. Três (6%) pacientes responderam que estavam completamente incapacitados. Os pacientes tiveram uma pontuação média de 73,16 pontos nos domínios do SF-36. Houve redução significativa da cifose em 12 meses (9,1±5,2 [min-máx 0-22]) na comparação com o pré-operatório (14,9±7,8 [min-máx 0-32]) (p≤0,01). Um paciente necessitou de retirada do implante em razão da proeminência sintomática do implante. Conclusão: Esta série de casos sugere que a técnica leva a resultados funcionais satisfatórios, sem falha do implante ou cifose pós-traumática após acompanhamento mínimo de 12 meses de tratamento. Nível de Evidência IV; Série de casos.

Correlation between types of mindset and quality of life evaluation in patients with scoliosis / Correlação entre os tipos de mentalidade e avaliação da qualidade de vida em pacientes com escoliose

ABSTRACT Scoliosis is a pathology with multiple etiologies that leads to aesthetic changes, increased morbidity and, especially, psychological damage. Objective: This work aims to compare two mindset types (fixed and growth) and assess levels of quality of life in individuals with scoliosis. Methods: Two questionnaires, Scoliosis Research Society-30 (SRS-30) and Early-Onset Scoliosis-24 Questionnaire (EOSQ-24), associated with the "Health Mindset Scale," were used. We applied the SRS-30 to patients who were independent or whose diagnosis of spinal deformity occurred after the age of 10 years. For patients diagnosed before the age of 10 or who presented dependence due to cognitive impairment, caregivers were subjected to the "Health Mindset Scale" and EOSQ-24 questionnaires. Results: The sample consisted of 35 patients aged from 4 to 46 years, the majority aged from 15 to 18 years old (42.9%), female (71.4%), and with neuromuscular scoliosis (28.6%). The only significant result (p = 0.060) was the increase in pain/discomfort scores in the EOSQ-24 for a patient with a growth mindset. Lastly, there was no statistical difference between groups, however, in patients with a growth mindset, there was a tendency (p = 0.060) to have a higher pain/discomfort score, assessed via the EOSQ-24 score, reported by the caregiver. Level of Evidence III, Retrospective Comparative Study.

RESUMO A escoliose é uma patologia com múltiplas etiologias e que acarreta alterações estéticas, aumento de morbidade e principalmente danos psicológicos. Objetivo: Comparar dois tipos de mindset (fixo e construtivo) e o nível de qualidade de vida. Métodos: Foram utilizados dois questionários, o Scoliosis Research Society-30 (SRS-30) e o Early-Onset Scoliosis-24 Questionnaire (EOSQ-24), associados à escala Health Mindset Scale. Aplicamos o SRS-30 em pacientes independentes ou cujo diagnóstico de deformidade na coluna ocorreu após os 10 anos. Já no caso de pacientes com diagnóstico antes dos 10 anos ou que apresentassem dependência devido a dificuldades cognitivas, os cuidadores foram submetidos à Health Mindset Scale e ao EOSQ-24. Resultados: A amostra foi composta por 35 pacientes com idades entre 4 e 46 anos, sendo a maioria entre 15 e 18 anos (42,9%), do sexo feminino (71,4%) e com escoliose do tipo neuromuscular (28,6%). O único resultado com significância (p = 0,060) foi o aumento dos escores de dor/desconforto nos questionários EOSQ-24 em paciente com mindset de crescimento. Por fim, não houve diferença estatisticamente significante entre os grupos, porém, em pacientes com mindset construtivo, houve tendência (p = 0,060) de maior escore de dor/desconforto avaliado por meio do EOSQ-24 e referido pelo cuidador.
