RESUMO

INTRODUCTION: Developmental dysplasia of the hip (DDH) includes a spectrum of clinical and imaging findings at birth or early infancy. The circumstances in which this condition is detected and managed may be heterogeneous in Brazil owing to its large territory and regional socio-economic differences. Mapping DDH perspectives in a country is fundamental for designing guidelines and strategies for public policy. This scoping review aims to map the available literature related to screening, diagnosis, treatment and outcomes of DDH in the Brazilian population to provide an overview of this condition and to describe regional variations in presentation and management across the country. METHODS AND ANALYSIS: This study will follow the methods outlined in the Joanna Briggs Institute Reviewers manual for conducting a scoping review. Relevant publications will be first searched in PubMed/MEDLINE, Scientific Electronic Library Online, Web of Science, Scopus, "Biblioteca virtual em saúde" and "Biblioteca Digital Brasileira de Teses e Dissertações" using search terms developed from a brief preliminary search of those databases. There were no language or date range limitations for study inclusion. Databases will be searched from their inception until February 2024. Titles and abstracts will be analysed by two or more independent reviewers to assess them against the inclusion criteria for the review. The search results and study inclusion process will be reported in full in the final version of the scoping review and presented in a Preferred Reporting Items for Systematic Reviews and Meta-analyses extension for scoping review (PRISMA-ScR) flowchart. The resulting data will be recorded and organised to present the key information contained in all examined articles. ETHICS AND DISSEMINATION: This review will include existing available studies and does not require a specific ethical review or approval. The final study will be submitted for presentation at conferences that focus on Brazilian healthcare and publication in peer-reviewed journals. This scoping review protocol was registered in the Open Science Framework. DOI registration (https://doi.org/10.17605/OSF.IO/V3AYH).

RESUMO

Abstract Objective: This study aimed to assess physical and mental health, and health-related quality of life (HRQL) parameters in adolescents with physical disabilities enrolled in a sports nongovernmental organization (NGO) versus adolescents without disabilities during coronavirus disease 2019 (COVID-19) pandemic. Methods: This cross-sectional study included 30 adolescents with disabilities and 86 adolescents without disabilities who responded to an online questionnaire with sociodemographic data and self-rated healthcare routine information during the COVID-19 quarantine. Validated self-report versions of the Strengths and Difficulties Questionnaire (SDQ), Pediatric Quality of Life Inventory 4.0 (PedsQL 4.0), Pittsburgh Sleep Quality Index (PSQI), and Pediatric Outcome Data Collection Instrument (PODCI) were also applied. Results: The median of emotional [4 (0-10) vs. 5 (0-10), p=0.018] and prosocial [7 (0-10) vs. 9 (3-10), p=0.006] problems was lower in adolescents with disabilities versus adolescents without disabilities. Adolescents with disabilities had significantly lower global function [68 (21-99) vs. 94 (67-100), p<0.001] and higher happiness scores in the PODCI scale [90 (65-100) vs. 80 (0-100), p=0.016] compared to controls. Logistic regression analysis demonstrated that physical activity/week (OR=1.03; 95%CI 1.01-1.05, p=0.002) was higher in adolescents with disabilities compared to adolescents without disabilities. However, housework activities (OR=0.14; 95%CI 0.04-0.43, p=0.001) and screen time ≥3 h/day (OR=0.09; 95%CI 0.02-0.38, p=0.001) were lower in adolescents with disabilities compared to adolescents without disabilities. Conclusion: Adolescents with disabilities attending a sports NGO were not at higher risk of adverse health-related indicators; despite showing reduced physical function, they reported more physical activity, higher happiness, and less screen time compared to adolescents without disabilities during the COVID-19 pandemic.

Resumo Objetivo: Avaliar os parâmetros de saúde física e mental, de qualidade de vida relacionada à saúde (QVRS), em adolescentes com deficiência física matriculados em organização não governamental (ONG) esportiva vs. em adolescentes sem deficiência, durante a pandemia da doença do coronavírus 2019 (COVID-19). Métodos: Este estudo transversal incluiu 30 adolescentes com deficiência e 86 adolescentes sem deficiência que responderam a questionário online com dados sociodemográficos e informações de rotina de saúde autoavaliadas durante a quarentena da COVID-19. Versões validadas de autorrelato do Strengths and Difficulties Questionnaire (SDQ), Pediatric Quality of Life Inventory 4.0 (PedsQL4.0), Pittsburgh Sleep Quality Index (PSQI) e Pediatric Outcome Data Collection Instrument (PODCI) também foram aplicadas. Resultados: A mediana de problemas emocionais [4(0-10) vs. 5(0-10),p=0,018] e pró-social [7(0-10) vs. 9(3-10),p=0,006] foi menor em adolescentes com deficiência vs. adolescentes sem deficiência. Adolescentes com deficiência tiveram função global significantemente inferior [68(21-99) vs. 94(67-100),p <0,001] e pontuações de felicidade mais altas do PODCI [90(65-100) vs. 80(0-100),p=0,016] em comparação com o grupo sem deficiências. A análise de regressão logística demonstrou que a atividade física/semana (odds ratio — OR=1,03; intervalo de confiança — IC95%=1,01-1,05,p=0,002) foi maior nos adolescentes com deficiência. No entanto, atividades domésticas (OR=0,14; IC95%=0,04-0,43,p=0,001) e tempo de tela ≥3 horas/dia (OR=0,09; IC95%=0,02-0,38,p=0,001) foram menores nos adolescentes com deficiência. Conclusões: Os adolescentes com deficiência que frequentam uma organização não governamental (ONG) esportiva não tiveram maior risco de apresentar indicadores adversos à saúde; apesar de apresentarem função física reduzida, relataram mais atividade física, maior felicidade e menos tempo de tela em comparação com adolescentes sem deficiência durante a pandemia da COVID-19.

RESUMO

Children and adolescents with physical disabilities have motor and social-emotional challenges that interfere with their health-related quality of life and put them at greater risk of developing secondary conditions. Moreover, services that provide them therapies are more likely to be restricted, especially for the low-income population. There must be broader actions towards health promotion, offering not only means for physical habilitation and rehabilitation but for social and emotional improvements as well. This goal is attainable by adaptive sports and recreational activities where physical conditioning is accompanied by an improvement in self-esteem and social benefits. With the COVID-19 pandemic and social isolation, children and adolescents with physical disabilities were even further deprived of assistance. Our aim was to report the efforts of a non-governmental sports organization in maintaining physical and psychological care through virtual consultations and to analyze the perceptions of those affected by the process. Level of evidence IV; case series .

Crianças e adolescentes com deficiência física apresentam desafios motores e socioemocionais que interferem na qualidade de vida relacionada à saúde e os colocam em maior risco de desenvolver doenças secundárias. Além disso, estão mais sujeitos a restrições de serviços adequados que ofereçam terapias, principalmente para a população de baixa renda social. Torna-se necessário oferecer ações voltadas para a promoção da saúde em um sentido mais amplo, oferecendo não só meios de habilitação e reabilitação física, mas também de ganhos sociais e emocionais. Este objetivo pode ser atingido com esportes adaptados e atividades recreativas nos quais o condicionamento físico é acompanhado por ganhos em autoestima e benefícios sociais. Com a pandemia de COVID-19 e o isolamento social, crianças e adolescentes com deficiência física ficaram ainda mais privados de assistência. Relatamos aqui o esforço de uma organização não-governamental esportiva em manter o atendimento físico e psicológico por meio de consultas virtuais, e avaliamos as percepções das partes interessadas no processo.

RESUMO

Abstract Objective: To evaluate physical and mental health indicators in adolescents with preexisting chronic immunocompromised conditions during coronavirus disease 2019 (COVID-19) quarantine. Methods: A cross-sectional study included 355 adolescents with chronic conditions and 111 healthy adolescents. An online self-rated survey was used to investigate socio-demographic features, healthcare routine, and the quarantine impact on physical and mental health. The validated self-reported version of the Strengths and Difficulties Questionnaire (SDQ) was also applied. Results: The median of age [14 (10-18) vs. 15 (10-18) years, p = 0.733] and frequencies of female (61% vs. 60%, p = 0.970) were similar between adolescents with preexisting chronic conditions and healthy adolescents during quarantine of COVID-19 pandemic. The frequencies of abnormal total difficulties score of SDQ were similar in patients and controls (30% vs. 31%, p = 0.775). Logistic regression analysis showed that being female (OR = 1.965; 95% CI = 1.091-3.541, p = 0.024), fear of underlying disease activity/complication (OR = 1.009; 95%CI = 1.001-1.018, p = 0.030) were associated with severe psychosocial dysfunction in adolescents with chronic conditions, whereas school homework (OR = 0.449; 95% CI = 0.206-0.981, p = 0.045) and physical activity (OR = 0.990; 95% CI = 0.981-0.999, p = 0.030) were protective factors. Further analysis of patients with chronic immunocompromised conditions and previous diagnosis of mental disorders (9%) compared with patients without diagnosis showed higher median of total difficulties score (p = 0.001), emotional (p = 0.005), conduct (p = 0.007), peer problems (p = 0.001) and hyperactivity (p = 0.034) in the former group. Conclusion: Adolescents with preexisting chronic immunocompromised conditions during COVID-19 quarantine were not at higher risk of adverse health indicators. Being female, fear of underlying disease activity/complication, and household members working outside of the home were relevant issues for adolescents with preexisting chronic conditions. This study reinforces the need to establish mental health strategies for teens with chronic conditions, particularly during the pandemic.

RESUMO

Many experimental models exist to better understand the necrosis of the femoral head etiology, both in terms of the species variety in which necrosis is induced and in the operative techniques used for treatment. Objective: This study has two main objectives, the first is to review the literature concerning experimental models of avascular necrosis of the growing femoral head, the second, to demonstrate the experimental pig model's reproducibility using a pilot study. Methods: This was a bibliographic review to describe the attempts over time to find the best species and technique for induction that would reproduce ischemic necrosis of the growing femoral head in humans. Simultaneously, a pilot study was performed to verify the replication of induction in pigs, the species that has more similarities with the human hip. The pilot's methodological analysis consists of conventional radiology and verification of possible anatomical, pathological changes. Results: In imaging exams; lateral sub-dislocation of the femur head and triangular appearance of the head were observed, characterizing its flattening; in macroscopic examination, the femoral head flattening with femoral neck widening and shortening was identified; in histology, the proliferation of articular cartilage with the presence of vascular granulation regenerative tissue, with osteoclasts and fibrocartilaginous tissue in the metaphyseal femoral neck region was identified. Conclusion: The experimental pig model can be used as a valuable tool for the reproducibility of anatomical, pathological changes in ischemic necrosis of the growing femoral head. The model is reproducible and feasible and can be beneficial for future studies on the anatomical pathology of necrosis of the growing femoral head. Level of Evidence III, Literature Review .

Na tentativa de compreender melhor a etiologia da necrose da cabeça femoral, existe uma diversidade de modelos experimentais tanto no que diz respeito à variedade das espécies em que é induzida a necrose quanto nas técnicas operatórias utilizadas para o tratamento. Objetivo: Este trabalho tem fundamentalmente dois objetivos: a revisão da literatura concernente aos modelos experimentais da necrose avascular da cabeça do fêmur em crescimento e demonstrar a reprodutibilidade do modelo experimental do suíno por meio de um estudo piloto. Métodos: Foi realizada uma revisão bibliográfica descrevendo as tentativas ao longo do tempo em buscar qual seria a melhor espécie e técnica para indução que reproduzisse a necrose isquêmica da cabeça do fêmur em crescimento nos humanos. Simultaneamente foi feito um estudo piloto para verificar a replicação da indução na espécie suína, o espécime cujo quadril tem mais similaridades com o humano. A análise metodológica do piloto consiste na radiologia convencional e verificação das possíveis alterações anátomo patológicas. Resultados: Nos exames por imagem, foram observadas sub-luxação lateral da cabeça do fêmur e aparência triangular da cabeça, caracterizando o achatamento da mesma; no exame macroscópico, identificamos o achatamento da cabeça femoral com alargamento e encurtamento do colo; na histologia, identificamos a proliferação da cartilagem articular com presença de tecido regenerativo vascular de granulação, com osteoclastos e tecido fibrocartilaginoso na região metafisária do colo femoral. Conclusão: Podemos inferir que o modelo experimental suíno pode servir como ferramenta valiosa para a reprodutibilidade das alterações anátomo patológicas da necrose isquêmica da cabeça femoral em crescimento. O modelo é reprodutível e factível, servindo para estudos futuros sobre a anátomo patologia da necrose da cabeça do fêmur em crescimento. Nível de Evidência III, Revisão da Literatura .

RESUMO

Congenital clubfoot is one of the most common deformities at birth. The inadequacy or absence of treatment causes serious limitations for people with this condition. The initial treatment using the Ponseti method ensures functional results superior to other treatment modalities previously proposed. However, recurrences and neglected feet are still a challenge today. An understanding of the pathophysiology of the disease, as well as of the anatomy and local biomechanics and a thorough clinical and radiological evaluation of patients are essential to understanding the limits of the method and choosing the best treatment.

RESUMO

OBJECTIVE: To assess the possible factors that influence sleep quality in adolescents with and without chronic immunosuppressive conditions quarantined during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: This cross-sectional study included 305 adolescents with chronic immunocompromised conditions and 82 healthy adolescents. Online surveys were completed, which included questions on socio-demographic data and self-rated healthcare routine during COVID-19 quarantine and the following validated questionnaires: the Pittsburgh Sleep Quality Index (PSQI), Pediatric Quality of Life Inventory 4.0 (PedsQL4.0), and Pediatric Outcome Data Collection Instrument (PODCI). RESULTS: The median current age [14 (10-18) vs. 15 (10-18) years, p=0.847] and frequency of female sex (62% vs. 58%, p=0.571) were similar in adolescents with chronic conditions compared with healthy adolescents. The frequency of poor sleep quality was similar in both groups (38% vs. 48%, p=0.118). Logistic regression analysis, including both healthy adolescents and adolescents with chronic conditions (n=387), demonstrated that self-reported increase in screen time (odds ratio [OR] 3.0; 95% confidence interval [CI] 1.3-6.8; p=0.008) and intrafamilial violence report (OR 2.1; 95% CI 1.2-3.5; p=0.008) were independently associated with poor sleep quality in these adolescents. However, the PODCI global function score was associated with a lower OR for poor sleep quality (OR 0.97; 95% CI 0.94-0.99; p=0.001). Further logistic regression, including only adolescents with chronic conditions (n=305), demonstrated that self-reported increase in screen time (OR 3.1; 95% CI 1.4-6.8; p=0.006) and intrafamilial violence report (OR 2.0; 95% CI 1.2-3.4; p=0.011) remained independently associated with poor quality of sleep, whereas a lower PODCI global function score was associated with a lower OR for sleep quality (OR 0.96; 95% CI 0.94-0.98; p<0.001). CONCLUSION: Self-reported increases in screen time and intrafamilial violence report impacted sleep quality in both healthy adolescents and those with chronic conditions. Decreased health-related quality of life was observed in adolescents with poor sleep quality.

Resumo O pé torto congênito é uma das deformidades mais comuns ao nascimento. A inadequação ou ausência do tratamento provoca sérias limitações aos portadores desta condição. O tratamento inicial pelo método Ponseti garante resultados funcionais superiores a outras modalidades de tratamento propostas anteriormente, porém as recidivas e os pés negligenciados ainda são um desafio na atualidade. O entendimento da fisiopatologia da doença, da anatomia e biomecânica local e uma minuciosa avaliação clínica e radiológica dos pacientes são imprescindíveis para entendermos o limite do método e escolhermos o melhor tratamento.

RESUMO

Congenital femoral deficiency (CFD) is a rare disorder with several limb anomalies including limb shortening and knee cruciate ligament dysplasia.Limb lengthening is usually performed to correct lower limb discrepancy. However, complications, such as knee subluxation/dislocation, can occur during this treatment.Here, we explore CFD knee abnormalities and knee dislocation during limb elongation, discussing when and whether knee ligament reconstruction prior to the lengthening would be necessary to reduce the risk of knee dislocation.There is not enough support in the literature for the routine reconstruction of cruciate ligaments in CFD patients.Of note, in cases of severe anteroposterior or posterolateral rotatory instability, cruciate ligament reconstruction might be considered to decrease the risk of knee subluxation/dislocation during the lengthening treatment.

RESUMO

OBJECTIVE: The purpose of our study is to evaluate intraobserver and interobserver reliability of modified Waldenström classification system for Legg-Calvé-Perthes disease and assess the influence of the professional's area of expertise in the assessment. METHODS: Twelve evaluators assessed 40 pairs of pelvic radiographs of patients with Legg-Calvé-Perthes disease. After two weeks, a new evaluation was performed by the same evaluators. Kappa and Kendall's W indexes were used to evaluate both intraobserver and interobserver reliability and determine the influence of the evaluators' experience and area of expertise. RESULTS: The average intraobserver kappa value was 0.394, with a reasonable agreement level. The interobserver Kappa value was 0.243 in the first evaluation (95% CI, 0.227-0.259 and p < 0.0001) and 0.245 in the second evaluation (95% CI, 0.229-0.260 and p < 0.0001). The Kendall's W values obtained for pediatric orthopedists, radiologists and resident physicians were 0.686, 0.630 and 0.529 (p < 0.0001), respectively. Conclusion: The modified Waldenström classification presented both moderate and reasonable levels of intraobserver agreement, and reasonable level of interobserver agreement. The evaluators' degree of experience and area of expertise influenced the concordance level found. Level of Evidence II, Diagnostic Studies - Investigating a Diagnostic Test.

RESUMO

Cerebral palsy (CP) describes a group of disorders of movement, posture and balance caused by a non-progressive brain injury in the immature brain. It is the most prevalent cause of chronic motor disability in childhood, and although two thirds of CP children are able to walk, they show gait limitations. In this context, rehabilitation therapy can improve muscle balance and gait. Previous studies showed the importance of gait analysis as part of multidisciplinary tools for effective rehabilitation treatment. However, the high cost and the infrastructure required for the implementation of commercial gait analysis systems as well as the time-consuming preparation procedures, limit the access to this service. A low cost, non-restrictive, portable and of simple operation and installation system was developed based on Kinect v2 sensor. This study aims to validate it for capturing and analysing gait parameters in children with cerebral palsy. Several gait parameters from eleven CP patients with different levels of disability classified as a function of the Gross Motor Function Classification System (GMFCS) from II to III were recorded while they walked on a flat surface. The Kinect-based gait analysis system was compared with video-recording that yielded the same results. These results show the potential of Kinect to analyse gait in frail patient populations unobtrusively and with very low cost. More importantly, regarding to spatial parameters, the Kinect system was useful even for the worst case of GMFCS III that show a large gait variability with abnormal patterns.

RESUMO

OBJECTIVE: To retrospectively evaluate the preliminary postoperative results of modified Dega-type acetabular osteotomy to treat developmental dysplasia of the hip, confirming the efficacy and reproducibility of this technique. METHODS: This retrospective study included patients older than 18 months. A total of 19 hips underwent modified Dega osteotomy. RESULTS: Satisfactory results were obtained, with an average decrease of the acetabular index from 39.2 to 20.6 degrees. The final average center edge angle was 29.6 degrees. Hip joint congruence was reestablished in all cases, and as of this writing, only one case developed necrosis in the femoral head during follow-up. CONCLUSION: Modified Dega osteotomy demonstrated good initial results, as well as the potential for use in treating developmental dysplasia of the hip. Level of Evidence IV; Case series.

OBJETIVO: Avaliar, retrospectivamente, os resultados preliminares do pós-operatório de pacientes com displasia do desenvolvimento do quadril, tratados com osteotomia acetabular do tipo Dega modificada e, dessa forma, confirmar a eficácia da técnica. MÉTODOS: Neste estudo retrospectivo foram incluídos pacientes com idades acima de 18 meses. No total, 19 quadris foram submetidos à osteotomia de Dega modificada. RESULTADOS: Os resultados foram satisfatórios, com diminuição média do índice acetabular de 39,2 para 20,6 graus. A média final do ângulo centro-borda foi de 29,6 graus. Em todos os casos houve restabelecimento da congruência articular dos quadris e, até o momento, um caso apresentou necrose da cabeça do fêmur no mesmo período do seguimento. CONCLUSÃO: A osteotomia de Dega modificada demonstrou bons resultados iniciais e potencial para ser empregada no tratamento da displasia do desenvolvimento do quadril.

RESUMO

Biapical femoral deformities are challenging to treat. In order to correct concomitant metaphyseal and diaphyseal deformities of the femur, the authors propose a double femoral controlled osteotomy with combined internal fixation, consisting of a Puddu plate and an intramedullary nail. The method was described in two patients. Results were analyzed using a visual analog scale (VAS), the Lysholm score, and SF-36. No complications were found. Complete consolidation of the osteotomies and radiographic alignment correction were achieved. Results were obtained with a minimum follow-up of 66 months. Both patients had improved for pain (VAS from 60 to 40 and from 50 to 20 at reassessment), function (Lysholm score from 78 to 93 and from 55 to 73) and quality of life (SF-36, both mental - from 40.7 to 57.1 in case one and from 24.7 to 59.7 in case two - and physical - from 27.7 to 45.6 and from 28.2 to 46.8). The authors have found that this technique is a reliable, accurate, and reproducible solution for biapical deformities of the femur.

RESUMO

ABSTRACT Objective: To retrospectively evaluate the preliminary postoperative results of modified Dega-type acetabular osteotomy to treat developmental dysplasia of the hip, confirming the efficacy and reproducibility of this technique. Methods: This retrospective study included patients older than 18 months. A total of 19 hips underwent modified Dega osteotomy. Results: Satisfactory results were obtained, with an average decrease of the acetabular index from 39.2 to 20.6 degrees. The final average center edge angle was 29.6 degrees. Hip joint congruence was reestablished in all cases, and as of this writing, only one case developed necrosis in the femoral head during follow-up. Conclusion: Modified Dega osteotomy demonstrated good initial results, as well as the potential for use in treating developmental dysplasia of the hip. Level of Evidence IV; Case series.

RESUMO

INTRODUCTION: We attended three skeletally immature patients with Down syndrome (DS) with complaints of severe patellofemoral instability and dislocated patella (preoperatively, Dugdale classification IV or V), in addition to low functional capacity, with falls during gait. The technique (lateral release, medial capsulectomy, reconstruction of the medial patellofemoral ligament (MPFL) with the patellar ligament and associated techniques, and some knees) and results in three children with DS and bilaterally dislocated patella were revealed. CASE REPORT: Our minimum follow-up was 27 months and maximum was 105 months (average of 64 months). All children improved gait, patellar stability, Kujala (58.13%), and subjective IDKC (40.55%) scores and improved the congruence and the trochlea groove angles. CONCLUSION: The patellofemoral instability in children with DS is a challenge. We should use an arsenal of surgical techniques in this complex problem. We believe in early surgery to improve the formation of structures, especially in patients with gross instabilities and frequent falls. In all cases, we detected a weakness of medial components and lateral contracture, reconstructed the MPFL (we were the first researchers to describe this procedure for this group of patients), and performed a medial capsulectomy and lateral release. In some knees, intraoperatively, it was necessary to associate the reconstruction of the medial patellotibial ligament to improve instability. We consider fundamental analysis of the axis with panoramic radiographs and hemiepiphysiodes is in cases of asymmetric or severe valgus.
