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.

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.

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.

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.

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.

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.

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.

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. Nível de Evidência III, Estudo Retrospectivo Comparativo.

ABSTRACT: Objective: To carry out registration of patients with scoliosis under 18 years old, followed in a quarternary hospital of high complexity, who need surgical treatment, aiming to identify the reasons for the delay in treatment. Methods: Data collection was carried out in person and by spontaneous demand at the spinal orthopedic specialty outpatient clinic in a tertiary hospital of high complexity from January 2021 to December 2022. The results were compiled in the networked database (Red Cap®). Result: 59 patients were evaluated, 45 female (77.9%) and 14 male (22.1%), with a mean age of 13.7 years. Etiology: 30 idiopathic (50.8%), eight syndromic (13.5%), 11 neuromuscular (18.6%), and ten congenital (16.9%). Of the total, 46 (77.9%) were awaiting surgery and 13 (22.1%) were undergoing conservative treatment. The main causes of treatment delay: unavailability of intraoperative neurophysiological monitoring (19 - 41.3%); unavailability of specific surgical material (16 - 34.8%); difficulty of referral to our institution (6 - 13.1%); loss to follow-up (3 - 6.5%) and limitation in casting making (2 - 4.3%). The mean time between diagnosis and the first consultation is 17.25 months (0 - 140). The average surgical wait until December/2022 was 38.4 months (1 - 156). Conclusion: There is a lack of assistance in the steps of monitoring and treatment in the public health system, from directing the patient with scoliosis to the specialized center to performing the surgical procedure, mainly due to limitations in the use of intraoperative neurophysiological monitoring and the unavailability of specific materials to perform highly complex surgeries.

RESUMO: Objetivo: Descrever a epidemiologia de pacientes, menores de 18 anos, com escoliose que aguardam cirurgia em hospital quaternário de alta complexidade e observar os motivos que acarretam atrasos no tratamento. Métodos: Coleta de dados presencial e espontaneamente no ambulatório de ortopedia da coluna vertebral num hospital de alta complexidade, de janeiro de 2021 a dezembro de 2022. Os resultados foram compilados no banco de dados (Red Cap®). Resultados: Foram avaliados 59 pacientes, 45 mulheres (77,9%) e 14 homens (22,1%), com média etária de 13,7 anos. Etiologia: 30 idiopáticas (50,8%), 8 sindrômicas (13,5%), 11 neuromusculares (18,6%) e 10 congênitas (16,9%). Do total, 46 (77,9%) aguardam cirurgia e 13 (22,1%) estavam em tratamento conservador. As principais causas de atraso do tratamento cirúrgico foram: indisponibilidade de monitoração neurofisiológica intraoperatória (19 - 41,3%); indisponibilidade de implantes para escoliose (16 - 34,8%); dificuldade no referenciamento para instituição (6 - 13,1%); perda de seguimento (3 - 6,5%) e limitação na confecção de colete (2 - 4,3%). Tempo médio entre diagnóstico e primeiro atendimento de 17,25 meses (0 - 140). A média de espera cirúrgica até dezembro/2022 era 38,4 meses (1 - 156). Conclusão: Há carência assistencial nas etapas do acompanhamento e no tratamento no Sistema Único de Saúde, desde o direcionamento do paciente com escoliose ao centro especializado até a realização do procedimento cirúrgico, sobretudo devido à limitação na utilização de monitoração neurofisiológica intraoperatória e indisponibilidade de materiais específicos para realização de cirurgias de alta complexidade.

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.

ABSTRACT Objective: The objective was to conduct an analytical epidemiological study to understand the profile, treatment, and outcome of patients with spinal tumors in a Brazilian Quaternary Hospital of the SUS. Methods: A retrospective cohort analysis of data from the last five years was performed. It was described qualitative characteristics evaluated by absolute and relative frequencies and quantitative characteristics by sintetized measures. Associations between characteristics were verified using chi-square tests or exact tests. Results: 92 patients met the eligibility criteria. The mean age was 56.1 years (±14.7), with 48 men (52.2%) and 44 women (47.8%). The types of tumors organized in the three proposed groups had 19 multiple myelomas (20.7%), 62 metastases (67.3%), and 11 other tumors (12%). The neurological status measured through the ASIA score was A: 5.4%, B: 22.8%, C: 26.1%, D: 35.9%, E: 9.8%. Karnofsky was prevalent in the 50-70 range with 65.2%. The total hospitalization period had a mean of 22.8±18 days, preoperatively 11.9±9.2 days, and postoperatively 10.9±14 days. Karnofsky presented lower values according to the worst ASIA (p < 0.001). A total of 12 patients (13%) died during hospitalization. The total and postoperative length of stay was longer in patients who died (p = 0.002 and p < 0.001). Conclusions: This study provides epidemiological data that allow an understanding of the profile of patients with spinal tumors in the Brazilian Public Health System. The severity of the patients is higher when compared to most of the series cases in the literature. The patients with longer hospitalization stay died. Level of evidence IV; Case series.

Anatomic and functional analysis of thoracic kyphosis and lumbar lordosis / Avaliação anatômica e funcional da cifose torácica e lordose lombar / Análisis anatómica y funcionalde la cifosis torácica y la lordosis lumbar

ABSTRACT Objective: Rate and compare radiographic measurements of thoracic kyphosis and lumbar lordosis using anatomical and dynamic parameters. Methods: Measurements were performed on lateral radiographs of 10 adults of both sexes without spinal disease or deformity. Thoracic kyphosis and lumbar lordosis were measured using anatomical parameters (T1-T12, T4-T12, T5-T12 and L1-S1) or dynamic parameters (cervicothoracic or thoracolumbar inflection point). Results: Thoracic kyphosis and lumbar lordosis were different in 30% of subjects. Differences in thoracic kyphosis values were observed according to the anatomical reference used for measurement. Lumbar lordosis wasn`t statistical difference considering the anatomical or dynamic reference, but in 30% of the individuals the inflection point was different from the anatomical reference. Conclusions: Thoracic kyphosis and lumbar lordosis values differ according to anatomical and dynamic references. The reference used must be considered in the measurement and interpretation of values. Level of evidence IV; Case series.

Correlation of postoperative infection with the etiology of the disease in spinal surgery with instrumentation / Correlação da infecção pós operatória com a etiologia da doença na cirurgia de coluna instrumentada / Correlación de la infección postoperatoria con la etiología de la enfermedad en cirugía espinal instrumentada

ABSTRACT Objective: To evaluate the epidemiological characteristics of postoperative infection in surgeries of the spine with instrumentation in our service, and whether there is a correlation between the rate of postoperative infection and the etiology of the indication for the primary surgical procedure. Methodology: A retrospective search through medical records of patients who underwent spinal surgery with instrumentation in our hospital between 2015 and 2019 was performed, and the ones that evolved with acute or chronic postoperative infection with need for surgical cleaning to resolve it were selected. Cases of non-instrumented surgery, primary infection of the spine (osteomyelitis and spondylodiscitis) and superficial infection of the surgical wound without the need for surgical cleaning were excluded. Results: The rate of postoperative infection was 11.6%. In this group of patients who evolved with this complication, most were submitted to surgery primarily for trauma (38.9%), followed by degenerative disease (30.8%), neoplasm (19.2%), and deformity (15, 4%). However, when we analyzed these patients comparing them with the total number of cases of spinal surgery with instrumentation performed in the period, we obtained a higher prevalence of infection in patients operated for deformity (17.6%), followed by degenerative disease (13%), neoplasm (11.4%) and trauma (9.9%). This difference did not prove to be statistically significant (p = 0.79), nor the correlation with sex and age. Conclusion: In our study, proportionally, there was a difference in the prevalence of postoperative infection according to the etiological indication, being higher in cases operated for deformity, mainly due to neuromuscular disease. Level of evidence IV; A case series therapeutic study.

RESUMO Objetivo: Avaliar as características epidemiológicas da infecção pós-operatória nas cirurgias com instrumentação da coluna vertebral no nosso serviço, assim como se há correlação entre a taxa de infecção pós-operatória e a etiologia da indicação do procedimento cirúrgico primário. Metodologia: Foi realizada uma busca retrospectiva por meio dos prontuários de pacientes submetidos a cirurgia da coluna vertebral com instrumentação em nosso hospital entre 2015 e 2019, e que evoluíram com infecção pós-operatória aguda ou crônica com necessidade de limpeza cirúrgica para sua resolução. Foram excluídos os casos de cirurgias não instrumentadas, casos de infecção primária da coluna (osteomielite e espondilodiscite) e casos de infecção superficial da ferida operatória sem necessidade de limpeza cirúrgica. Resultados: A taxa de infeção pós-operatória foi de 11,6%. Deste grupo de pacientes que evoluíram com essa complicação a maioria foi submetida a cirurgia primariamente por trauma (38,9%), seguido de doença degenerativa (30,8%), indicação oncológica (19,2%), e deformidade (15,4%). Porém quando analisamos esses pacientes comparando-os com o total de casos de cirurgia na coluna vertebral com instrumentação realizadas no período, obtivemos uma prevalência maior de infecção em pacientes operados por deformidade (17,6%), seguido de doença degenerativa (13%), doença oncológica (11,4%) e trauma (9,9%). Essa diferença não mostrou ser estatisticamente significativa (p=0,79), assim como a correlação com sexo e idade. Conclusão: Em nosso estudo, proporcionalmente, houve diferença na prevalência de infecção pós-operatória de acordo com a indicação etiológica, sendo maior nos casos operados por deformidade, principalmente em decorrência de doença neuromuscular. Nível de evidência IV; Estudo terapêutico de série de casos.

RESUMEN Objetivo: evaluar las características epidemiológicas de la infección postoperatoria en cirugías de columna con instrumentación en nuestro servicio, así como si existe una correlación entre la tasa de infección postoperatoria y la etiología de la indicación para el procedimiento quirúrgico primario. Metodología: se realizó una búsqueda retrospectiva a través de los registros médicos de pacientes que se sometieron a cirugía de columna con instrumentación en nuestro hospital entre 2015 y 2019, y que evolucionaron con infección postoperatoria aguda o crónica con necesidad de una limpieza quirúrgica para resolverlo. Se excluyeron los casos de cirugía no instrumentada, infección primaria de la columna (osteomielitis y espondilodiscitis) y infección superficial de la herida quirúrgica sin necesidad de limpieza. Resultados: la tasa de infección postoperatoria fue del 11,6%. De este grupo de pacientes que evolucionaron con esta complicación, la mayoría fueron sometidos a cirugía principalmente por trauma (38.9%), seguidos de enfermedad degenerativa (30.8%), neoplasia (19.2%) y deformidad (15, 4%). Sin embargo, cuando analizamos a estos pacientes comparándolos con el número total de casos de cirugía de columna con instrumentación realizada en el período, obtuvimos una mayor prevalencia de infección en pacientes operados por deformidad (17,6%), seguido de enfermedad degenerativa (13%), neoplasia (11.4%) y trauma (9.9%). Esta diferencia no resultó ser estadísticamente significativa (p = 0,79), así como la correlación con el sexo y la edad. Conclusión: En nuestro estudio, proporcionalmente, hubo una diferencia en la prevalencia de infección postoperatoria según la indicación etiológica, siendo mayor en los casos operados por deformidad, principalmente debido a enfermedad neuromuscular. Nivel de evidencia IV; Estudio terapéutico de serie de casos.
