ABSTRACT
Gancao Fuzitang originates from the Treatise on Febrile Diseases and Miscellaneous Diseases (《伤寒杂病论》) and is mainly used to treat pain in the bones and joints and symptoms such as no flexion or extension. It has the effect of tonifying the spleen and kidney and removing dampness and turbidity, so it is widely used in the clinical treatment of various bone and joint diseases. This article reviewed the clinical research and mechanism of Gancao Fuzitang in the treatment of bone and joint diseases. The research has found that this prescription has good efficacy in treating bone and joint diseases such as rheumatoid arthritis, rheumatoid arthritis, ankylosing spondylitis, gout, and intervertebral disc herniation. Its mechanism of action may be related to regulating the level of inflammatory factors, antioxidation, and the protein expression of inflammatory and apoptotic cell-related pathways, improving bone and joint diseases, and alleviating related symptoms. This study can provide a reference for further deepening the research on the prevention and treatment of bone and joint diseases with Gancao Fuzitang.
ABSTRACT
BACKGROUND:Exosomes are vesicle-like structures secreted by cells into extracellular compartments in the form of cytosol,which contain a large amount of microRNAs with important intercellular communication roles.MicroRNAs in exosomes rely on exosome transport and are able to enter target cells to exert important biological regulatory effects.In common bone and joint diseases,abnormal or damaged bone metabolism releases a large number of exosomes,while some exosome-derived microRNAs also promote the progression of osteoarthritis.Therefore,exosome-derived microRNAs are closely related to the skeletal system and are important for the development as well as diagnosis and treatment of many osteoarticular diseases. OBJECTIVE:To review the research progress of exosome-derived microRNAs in bone metabolism and bone and joint diseases. METHODS:Using"exosomes,extracellular vesicle,microRNA,miRNA,bone,bone diseases,bone formation,bone regeneration,bone resorption,bone destruction"as Chinese and English search terms,articles were searched on CNKI,Metasys,and PubMed databases.Finally,86 articles were included for summarization. RESULTS AND CONCLUSION:Exosome-derived microRNAs can regulate bone metabolism by affecting bone formation and bone resorption,and are closely related to the development of bone and joint diseases such as fracture healing,osteoporosis,osteoarthritis,rheumatoid arthritis,osteonecrosis of the femoral head,and osteosarcoma.Exosome-derived microRNAs will be an effective means of diagnosis and treatment of certain bone and joint diseases in the future.However,the current research on exosome-derived microRNAs in osteoarthritic diseases is limited,and more explorations and researches are still needed to diagnose and treat osteoarthritic diseases using exosome-derived microRNAs.
ABSTRACT
Abstract Acute calcific periarthritis (ACP) is defined as periarticular inflammation associated with intra-articular deposits of hydroxyapatite and other basic calcium phosphate crystals. Patients with ACP present with a sudden onset of pain, together with localized swelling, as well as erythema, tenderness, and reduced range of motion. Familiarity with the clinical and radiological manifestations of ACP aids in the diagnosis and helps differentiate it from other conditions, particularly infectious or inflammatory pathologies such as septic arthritis and gout, thereby reducing the number of unnecessary diagnostic and therapeutic procedures. The objective of this pictorial essay is to illustrate the imaging findings of ACP in various joints, with an emphasis on the findings obtained by magnetic resonance imaging.
Resumo A periartrite cálcica aguda (PCA) é uma inflamação periarticular aguda associada a depósitos justa-articulares de hidroxiapatita e outros cristais básicos de fosfato de cálcio. Os pacientes apresentam início súbito de dor, edema localizado, eritema, sensibilidade e redução da amplitude de movimentos. A familiaridade com as manifestações clínicas e radiológicas da PCA facilita o diagnóstico e permite diferenciá-la de outras entidades, em particular, com doenças infecciosas ou inflamatórias, como artrite séptica e gota, reduzindo procedimentos diagnósticos e terapêuticos desnecessários. O objetivo deste ensaio iconográfico é ilustrar os achados de imagem de PCA em algumas articulações, com ênfase na ressonância magnética.
ABSTRACT
Varmam- a discrete medical science and a great contribution of Siddhars to Tamil Nadu. It encompases Varma martial arts, Varma therapy, internal and external medicines. Varma therapy and medicines effectively treat neuro musculoskeletal conditions which is admirable. Shoulder pain is most common orthopaedic condition. It is the third common cause of musculoskeletal consultations in primary care. Approximately 1% of adult develops new shoulder pain annually. Common pathological conditions of shoulder like rotator cuff disorders and adhesive capsulitis etc exhibits similar clinical features like pain and stiffness of shoulder joint and restricted movements. Varma therapy rearranges and regulates the “Vaasi” and consequently helps to maintain the equilibrium of trihumours (Vatham, Pitham, Kapham). This review article explicates the Varma points for the treatment of shoulder pathological conditions, the exact anatomical location of Varma points and the appropriate method of its manipulation, certainly a key to further research articles.
ABSTRACT
Despite the availability of drugs and pharmaceutical forms for the treatment of rheumatoid arthritis and osteoarthritis symptoms, their adverse effects and lack of response to therapy reinforces the need to search for new technological formulation strategies capable of delaying the progress of the disease, with better therapeutic results and prolonged control of arthropathy. The aim of this bibliographic review was to identify new reported therapeutic approaches for these diseases. The treatment of rheumatoid arthritis and osteoarthritis is an unresolved challenge, due to the complexity of these diseases. Thus, the new therapies aim to suppress inflammatory mediators and to reduce the degradation of the extracellular matrix. In addition, the use of nano and microtechnology takes advantage of the properties of polymers, lipids, peptides, and nucleic acids to develop controlled drug release systems, aiming to obtain highly effective precision therapies, whose usefulness should be evaluated in future clinical trials.

Nucleotide binding oligomeric dome-like receptor protein 3 (NLRP3) inflammasome is an intracellular sensing protein complex, and it is an important player in the innate immune system, capable of sensing foreign pathogens and endogenous danger signals. After tissue injury, the activation of the NLRP3 inflammasome induces the release of the pro-inflammatory cytokines interleukin (IL)-1β and IL-18, while promoting gasdermin D-mediated pyroptosis. Existing studies have shown that NLRP3 inflammasome plays a key role in the occurrence and development of common bone and joint diseases such as osteoporosis, osteoarthritis, rheumatoid arthritis, and gouty arthritis by inducing inflammatory cascade reaction and accelerating bone resorption and cartilage destruction. Therefore, blocking the NLRP3 inflammasome signaling pathway may be an effective strategy to treat or prevent bone and joint diseases. Currently, researchers have developed and tested several drugs that selectively target the NLRP3 inflammasome in animal and clinical studies, but the progress has been poor due to obvious side effects and high prices. Traditional Chinese medicine (TCM) has been widely recognized in the treatment of bone and joint diseases due to its unique advantages of multi-target, multi-pathway, multi-mechanism synergism, low price, and low side effects. With the deepening of research, the targeted intervention of NLRP3 inflammasome by TCM in the treatment of bone and joint diseases has attracted wide attention. In this paper, the mechanism of NLRP3 inflammasome in osteoarthritis was summarized by analyzing relevant literature in China and abroad in recent years, and the progress of targeted intervention of NLRP3 inflammasome by TCM in the treatment of bone and joint diseases was systematically reviewed, so as to provide new ideas and theoretical basis for the treatment of bone and joint diseases.

ABSTRACT
Objective:To evaluate the efficacy of certolizumab pegol (CZP) in the treatment of Chinese women of childbearing age with inflammatory joint diseases and the effect of intrauterine exposure on infant vaccination and risk of infection.Methods:This study is a retrospective observation study, including female patients of childbearing age who were treated with CZP in the outpatient clinic from November 2019 to October 2020. The patients were followed up for 24 weeks, and the related data was collected. We adopted disease activity score-28 for rheumatoid arthritis with CRP (DAS28-CRP), clinical disease activity index (CDAI) and simplified disease activity index (SDAI) to evaluate disease activity. Bath ankylosing spon-dylitis disease activity index (BASDAI) and ankylosing spondylitis disease activity score (ASDAS-ESR) were used to assess the disease activity of patients with ankylosing spondylitis or spondyloarthritis (AS/SpA). Low disease activity (LDA), the dosage of glucocorticoid (GC) and the qualified rates of ACR20 and ASAS20 were calculated to validate the efficacy of CZP. The data of infants vaccination and infection was recorded to estimate the effect of intrauterine exposure on infants. Correlation analysis were performed using paired t test or Mann Whitney test. All statistical tests were bilateral, with a significance of P<0.05. Results:Twenty women entered the study and fifteen completed, including eight patients with RA, six patients with AS and 1 patient with SpA. The average age was (30±5) years and the median symptom duration was 5.0 (3.0, 6.5) years. When these RA patients were enrolled into the study, DAS28-CRP, CDAI and SDAI were (3.4±1.2), 15.5(9.5, 21.0) and (18±12) respectively; and after the use of CZP, the DAS28-CRP, CDAI and SDAI changed to (2.5±0.9)( t=2.48, P=0.042), 4.5(3.5, 10.8) ( U=12.50, P=0.040) and (9±6) (t=2.76, P=0.028). At the first follow-up, the ACR20 rate was 50%. and at the end of the study, the LDA rate was 75%(6/8), three(37.5%) women reduced the dosage of GC. Among the AS/SpA patients, BASDAI was 19.0(14.5, 26.0) and ASDAS-ESR was (2.4±1.0) at first, while after treatment, BASDAI turned into 9.0(1.0, 10.5) ( U=11.50, P=0.100) and ASDAS-ESR turned into (1.4±0.5) ( t=3.44, P=0.014). The ASAS20 rate at the first follow-up was 71.4%(5/7), and 85.7%(6/7) at the end of the study. Four patients experienced adverse events, resulting in drug withdrawal. Three women were pregnant when they were enrolled into the study, and three others became pregnant during the research. Six infants were vaccinated with live attenuated vaccines and inactivated vaccines according to the plan. No adverse event related to vaccination was reported, but one of the babies had perianal abscess and the other one had cold symptoms, while both improved after treatment. Conclusion:CZP can effectively control disease activity of women with inflammatory joint diseases during pregnancy, and intrauterine exposure is safe to infants during the study period.
ABSTRACT
Objective To investigate the prevalence of osteoarthrosis and the association between hot spring bathing and osteoarthrosis among local adults in typical hot spring areas of Guizhou Province. Methods A face-to-face questionnaire survey was conducted among residents aged from 30 to 65 in five typical hot spring areas, including Xifeng(Xifeng County, Guiyang), Jianhe(Jianhe County, Qiandongnan), Fodingshan(Shiqian County, Tongren), Guiyu(Wudang District, Guiyang)and Huishangu(Suiyang County, Zunyi). Residents' basic information, bone and joint diseases prevalence, hot spring bathing, and other health-related behaviors were investigated in this study. The prevalence of local bone and joint diseases was analyzed, and binary logistic regression was used to calculate OR(95%CI)to analyze the association between hot spring bathing and bone and joint diseases. Results A total of 3 708 adults(1 648 males and 2 060 females)were included as the statistical analysis survey subjects, and 794 people reported bone and joint diseases, accounting for a prevalence rate of 21.41%, 95% CI: 0.201-0.227. The prevalence of females(24.56%)was higher than that of males(17.48%)(P < 0.001). The prevalence rates of diseases increased with age(χtrend2=130.265, P < 0.001). There were also statistically significant differences in the prevalence rate of bone and joint diseases among different genders, age groups, occupations, education levels, and smoking behaviors(P < 0.05). After gender, age, occupation, education and smoking were adjusted for, compared with the group who never took hot spring baths, participants who took hot spring baths occasionally(OR=0.793, 95%CI: 0.631-0.996)and frequently(OR=0.713, 95%CI: 0.536-0.948)were associated with a lower risk of bone and joint diseases. Conclusion The prevalence of osteoarthrosis is 21.41% in the typical hot spring areas of Guizhou Province. Older or females have a higher risk of prevalence of bone and joint diseases. Hot spring bathing may be associated with a lower risk of bone and joint diseases.

ABSTRACT
INTRODUÇÃO: A Osteoartrite (OA) é uma doença musculoesquelética com predomínio na população idosa. O tratamento com Laserterapia tem sido um dos métodos seguros e não invasivos para o tratamento da OA. OBJETIVO: Observar a influência na dor, rigidez e função em idosos antes e depois da aplicação da laserterapia associados a exercícios domiciliares. MÉTODOS: Dez pacientes idosos com OA de joelho, submetidos a 12 sessões de Laserterapia, 3 vezes por semana e orientados a realizarem exercícios domiciliares durante o período do estudo. Foi utilizado o Laser de baixa potência Class 3B Chattanooga, com energia total de 36J (divididos em 6 pontos- 6J por ponto) conforme a dosagem da World Association of Laser Therapy (WALT). Para mensuração do quadro álgico foi utilizados a Escala Visual Analógica (EVA); Índice de Osteoartrite de Western Ontario (WOMAC) e Índice de Lequesne para dor, rigidez e funcionalidade. Os exercícios domiciliares foram explicados e demonstrados pelo avaliador e orientado a realizar 3 vezes por semana durante 12 sessões. RESULTADOS: Observamos que após aplicações de Laserterapia e exercícios domiciliares, não houve melhora na EVA, porém com melhora significativa nos quesitos WOMAC geral (p=0,01) e função (p=0,001) enquanto os demais não houve significância (p>0,5) quando avaliados por meio do t-test, já na comparação entre questionários houve correlação forte em WOMAC e LEQUESNE com a Correlação de Pearson. CONCLUSÃO: Pode-se concluir que a Laserterapia associada a exercícios domiciliares não evidencia melhora significativa do quadro álgico através da EVA, podendo ser uma resposta subjetiva com dificuldade de compreensão pelos pacientes, porém foi observado melhora significativa na evolução funcional do paciente medidas pelos questionários WOMAC e LEQUESNE nos pacientes com OA de joelho.
INTRODUCTION: Osteoarthritis (OA) is a musculoskeletal disease with predominance in the elderly population. Laser therapy has been one of the safe and non-invasive methods for treating OA. OBJECTIVE: To observe the influence on pain, stiffness and function in the elderly before and after the application of home exercise laser therapy. METHODS: Ten elderly patients with knee OA who underwent 12 laser therapy sessions 3 times a week. The Chattanooga Class 3B Low Power Laser was used, with a total energy of 36J (divided into 6 points - 6J per point) according to the dosage of the World Association of Laser Therapy (WALT). We used the Visual Analog Scale (VAS) for pain; Western Ontario Osteoarthritis Index (WOMAC) and Lequesne Index for pain, stiffness and functionality. Home exercises were explained and demonstrated by the evaluator and instructed to perform 3 times a week during 12 sessions. RESULTS: We observed that after laser therapy and home exercises, there was no improvement in VAS but there was significant improvement in the general WOMAC (p = 0.01) and function (p = 0.001), while the others were not significant (p> 0, 5), when compared to the t-test, when compared to the Pearson correlation, there was an improvement in the WOMAC and LEQUESNE questionnaires. CONCLUSION: It can be concluded that after applying home exercise laser therapy, there was no significant improvement in pain through VAS, which may be a subjective response with difficulty for patients to understand, but there was a significant improvement in the patient's functional evolution measured by the questionnaires.

Objective: To explore the feasibility of T1ρ technique in evaluating ankle osteochondral lesions of talus (OLT). Methods: Totally 40 patients with ankle OLT underwent both conventional MRI and T1ρ imaging, also arthroscopy examination within 1 week. Conventional MRI,arthroscopy and T1ρ imaging were observed, and ankle OLT were classified into - type (type - injury group, respectively) according to the improved Hepple classification standards. Then normal cartilage areas of 20 cases were randomly selected as the normal control group. T1ρ values of cartilage in each group were measured and analyzed. The consistency of OLT typing Results: using conventional MRI and arthroscopy was compared. Results: T1ρ images could clearly show ankle talus cartilage, and the colorific orders were different according to the degree of injuries. T1ρ values of cartilage increased with the aggravation of cartilage damage. There was no statistically difference (P=0.12) in T1ρ values of damaged cartilage of type injury group ([43.07±2.05]ms) and type Ⅱ injury group ([45.24±2.19]ms), whereas statistically differences of T1ρ values of damaged cartilage were found among other groups (P<0.05). The consistency of OLT typing Results: using conventional MRI and arthroscopy was good (Kappa=0.80, P<0.01). Conclusion: T1ρ technique can clearly display the talus cartilage of the ankle joint and quantitatively evaluate the degree of talus cartilage damage, especially for patients with early talus cartilage damage.
ABSTRACT
ABSTRACT Objective To compare screw fixation strength for subtalar arthrodesis. Methods Eight matched pairs of cadaver feet underwent subtalar joint arthrodesis with two 7.3mm cannulated screws. Randomization was used to assign screw orientation, such that one foot in each pair was assigned dorsal to plantar screw orientation (DP Group), and the other foot, plantar to dorsal orientation (PD Group). Standard surgical technique with fluoroscopy was used for each approach. Following fixation, each specimen was loaded to failure with a Bionix ® 858 MTS device, applying a downward axial force at a distance to create torque. Torque to failure was compared between DP and PD Groups using Student's t test, with p=0.05 used to determine statistical significance. Results Statistical analysis demonstrated that the mean torque to failure slightly favored the DP Group (37.3Nm) to the PD Group (32.2Nm). However, the difference between the two groups was not statistically significant (p=0.55). Conclusion In subtalar arthrodesis, there is no significant difference in construct strength between dorsal-to-plantar and plantar-to-dorsal screw orientation. The approach chosen by the surgeon should be based on factors other than the biomechanical strength of the screw orientation.
RESUMO Objetivo Comparar a força de fixação dos parafusos para artrodese subtalar. Métodos Oito pares de pés de cadáveres frescos foram submetidos à artrodese da articulação subtalar com dois parafusos canulados de 7,3mm. A randomização foi usada para atribuir a orientação do parafuso, de modo que um pé em cada par foi designado com orientação de dorsal para plantar (Grupo DP), e o outro pé com orientação de plantar para dorsal (Grupo PD). Técnica cirúrgica padrão com radioscopia foi usada para os procedimentos. Após a fixação, cada amostra foi testada até a falha com um dispositivo Bionix®858 MTS, aplicando força axial descendente a uma distância para criar torque. O torque de falha foi comparado entre os Grupos DP e PD, usando o teste t de Student, com p=0,05 usado para determinar significância estatística. Resultados A análise estatística demonstrou que a média do torque até a falha favoreceu ligeiramente o Grupo DP (37,3Nm) em relação ao PD (32,2Nm). No entanto, a diferença entre os dois grupos não foi estatisticamente significativa (p=0,55). Conclusão Na artrodese subtalar, não há diferença significativa na força de compressão entre as orientações dos parafusos dorsal-plantar e plantar-dorsal. A abordagem escolhida pelo cirurgião deve ser baseada em outros fatores, sem preocupação com a força biomecânica da orientação dos parafusos.

ABSTRACT
Introducción: El desplazamiento discal es la artropatía temporomandibular más común. Los desplazamientos discales sin Reducción (DDSR) constituyen una condición clínica en la cual en boca cerrada el disco articular se encuentra desplazado completamente, sin contacto con la vertiente anterior de la cabeza mandibular y en boca abierta el disco no es recapturado. El tratamiento quirúrgico realizado es la discopexia. A pesar de toda la información presente en la bibliografía aún existe controversia entre la elección de tratamiento del DDSR. Objetivo: Presentar la experiencia clínica, quirúrgica e imagenológica de la discopexia en DDSR mediante la presentación de una serie de casos. Metodología: Se realizó un estudio retrospectivo de las historias clínicas del Servicio de Cirugía Bucal y Maxilofacial del hospital General del Oeste "Dr. José Gregorio Hernández", Distrito Capital, Venezuela, entre 2014-2018; se seleccionaron seis casos clínicos que presentaban DDSR, los cuales fueron intervenidos con discopexia, posteriormente se evaluaron clínica e imagenológicamente. Resultados: Los seis casos presentaron particularidades en el transcurso del tratamiento desde la fase inicial y en la postoperatoria. Se evidenció una franca mejoría en las manifestaciones clínicas, en contraste, la resonancia magnética postoperatoria, el cual reveló el desplazamiento discal nuevamente. Conclusiones: La estabilidad en la reubicación discal postoperatoria depende de múltiples factores, tales como la estabilidad oclusal, muscular y presencia de hábitos parafuncionales. El aumento en la apertura bucal fue la característica común en todos los pacientes de este estudio así como la disminución de la sintomatología dolorosa.
Introduction: Disc displacement is the most common temporomandibular arthropathy. The displacements without reduction (DDSR) become a clinical practice in the closed mouth the articular disc is completely displaced, without contact with the anterior vertical of the mandibular head and in the open mouth the disc is not recaptured. The surgical treatment performed is discopexy. Despite all the information present in the literature there is still controversy between the choice of treatment of the DDSR. Objective: To present the clinical, surgical and imaging experience of discopexy in DDSR by presenting a series of cases. Methodology: A retrospective study of the clinical records of the Oral and Maxillofacial Surgery Service of the General del Oeste Hospital "Dr. José Gregorio Hernández ", Capital District, Venezuela, between 2014-2018; Six clinical cases were selected that presented DDSR, which were operated on with discopexy, and then evaluated clinically and imaging. Results: The six cases present particularities in the course of the treatment from the initial phase and in the postoperative period. The evidence is improved in the clinical manifestations, in contrast, in the postoperative magnetic resonance, in the articular disc it moved again. Conclusions: Stability in postoperative disc relocation depends on multiple factors, such as occlusal stability, muscle stability and the presence of parafunctional habits. The increase in oral opening was the common feature in all the patients for this study, as well as the decrease in painful symptoms.

The objectives of this study were to demonstrate the lesions that affect athlete bulls and to correlate the disorders with weight, age, affected limb and region of the limb. The present study was accomplished using radiographic images of athletic rodeo bulls collected from the medical and surgical records of the large animal service at the veterinary hospital. Radiographic images were evaluated for 136 bulls that were taken care of at the Veterinary Hospital, ranging in age from 4 to 13 years, with an average weight of 800kg and proven prior physical activity through participation in rodeos. The chi-square or Fisher's exact test was used to assess the association between the studied variables. It was observed that 71.6% of the bulls studied and suffering from lameness had radiographic lesions, predominantly in experienced animals. Enthesopathy in starter and experienced bulls, septic arthritis in starter bulls, and fractures and degenerative joint disease in experienced bulls were the most frequent radiographic lesions diagnosed. The region of limb where the majority of radiographic changes occurred was the digits. Risk factors and occurrence of diseases of the locomotor system in athletic bulls are similar to those in sport equines.(AU)
O objetivo desse trabalho foi demostrar quais lesões acometem touros atletas, correlacionando as desordens com peso, idade, membro e região afetada. O presente estudo foi realizado utilizando radiografias de touros atletas de rodeio, após levantamento dos prontuários clínicos e cirúrgicos do serviço de grandes animais de um hospital veterinário. Foram avaliadas radiografias de 136 touros que haviam sido atendidos em tal hospital, com idade variando de quatro a 13 anos, com média de peso de 800kg e realizavam participação em rodeios. Para avaliar a associação entre as variáveis estudadas foi utilizado o teste exato de Fischer e o Qui-quadrado. Observou-se que 71,6% dos touros estudados que claudicavam, apresentavam lesões radiográficas, predominantemente em animais mais experientes. A entesiopatia em todos os animais, artrite séptica nos touros iniciantes, fraturas e doença articular degenerativa nos touros mais experientes, foram as alterações radiográficas mais frequentes. As regiões com maior ocorrência de lesões radiográficas foram os dígitos. Os fatores de risco para ocorrência de doenças no sistema locomotor de touros atletas são diversos, similares aos que ocorrem nos equinos atletas.(AU)

Abstract Objective: To determine the size of the ischiofemoral space (IFS) and quadratus femoris space (QFS) in patients with and without ischiofemoral impingement (IFI). Materials and Methods: Case-control study including consecutive patients submitted to magnetic resonance imaging (MRI) of the hip joint during a three-month period. Patients with deep gluteal pain who tested positive for IFI on at least one clinical test and showed signal changes in the quadratus femoris muscle on MRI were categorized as having a confirmed diagnosis of IFI. Results: Final sample comprised 50 patients submitted to unilateral MRI of the hip joint. The mean age was 47.3 ± 14.0 years (range, 22-76 years), and 33 (66%) of the patients were women. A diagnosis of IFI was made in 6 patients (12%), all of whom were female. On average, IFS and QFS were significantly smaller in IFI group than in control group (11.1 ± 2.7 mm versus 27.5 ± 6.5 mm and 5.3 ± 1.8 mm versus 18.8 ± 4.8 mm, respectively; p < 0.001 for both). Conclusion: Results of specific clinical tests and MRI findings indicate that the IFS and QFS are significantly reduced in patients with IFI.
Resumo Objetivo: Avaliar, prospectivamente, os valores médios dos espaços isquiofemoral e quadrado femoral em pacientes com impacto isquiofemoral e em um grupo controle. Materiais e Métodos: Estudo prospectivo incluindo pacientes submetidos a ressonância magnética da articulação do quadril em um intervalo de três meses. Os pacientes com dor glútea profunda, com pelo menos um teste clínico positivo para impacto isquiofemoral e alterações de sinal no músculo quadrado femoral na ressonância magnética, foram diagnosticados com impacto isquiofemoral. Resultados: A amostra final consistiu de 50 pacientes submetidos a ressonância magnética unilateral da articulação do quadril. A idade média foi 47,3 ± 14,0 anos (intervalo de 22 a 76 anos) e 33 (66%) eram mulheres. O diagnóstico de impacto isquiofemoral foi observado em 6 (12%) pacientes, todas mulheres. Os pacientes com impacto isquiofemoral mostraram redução significativa nos espaços isquiofemoral e quadrado femoral quando comparados ao grupo controle: 11,1 ± 2,7 mm versus 27,5 ± 6,5 mm e 5,3 ± 1,8 mm versus 18,8 ± 4,8 mm, respectivamente (p < 0,001 para ambos os grupos). Conclusão: Os pacientes com diagnóstico de impacto isquiofemoral apresentaram redução significativa dos espaços isquiofemoral e quadrado femoral após análise prospectiva baseada em testes clínicos específicos e ressonância magnética.
ABSTRACT
Abstract Snapping scapula syndrome manifests as an audible or palpable crackling during the sliding movements of the scapula over the rib cage, often perceived during physical or professional activities. It can be caused by morphological alteration of the scapula and rib cage, by an imbalance in periscapular musculature forces (dyskinesia), or by neoplasia (bone tumors or soft tissue tumors). In this pictorial essay, we review the main causes of snapping scapula syndrome, exemplified by a collection of didactic cases.
Resumo A síndrome da escápula em ressalto manifesta-se como uma crepitação audível ou palpável durante os movimentos de deslizamento da escápula sobre o gradil costal. Frequentemente percebida em atividades físicas ou profissionais, as suas causas podem ter origem na alteração morfológica da escápula e gradil costal, no desequilíbrio de forças da musculatura periescapular (discinesia) ou ainda em tumores ósseos ou de partes moles. O presente estudo revisou de forma ilustrativa as principais causas da síndrome da escápula em ressalto, exemplificadas por meio de uma coletânea de casos didáticos.
ABSTRACT
The prescription composition and the technology of a new type of specialized product - biologically active additive BAAhave been scientifically grounded. The pharmacological properties and functional orientation of the active principles of theformulation components of the dietary supplements were studied, which made it possible to determine the quantitative andqualitative composition of the formulation which has a synergistic effect on metabolic processes in the presence ofdeforming osteoarthrosis: bamboo extract, glucosamine and chondroitin, aloe vera extracts, leaves and grape seeds, vitaminand mineral composition with green tea extract, and the antioxidant complex "Cifrol-5". A production technology providinghigh consumer performance for the developed product was approved. Clinical trials involving two groups of women aged44-49 with deforming osteoarthritis of the knee joints confirmed the functional properties of the complex. The first groupreceived the BAA, the second was a control group. Changes in the control indicators were registered after dietary therapyor in clinically significant periods of patient recovery. The control indicators were joint soreness, skin, hair, and nailcondition, and the recovery time of postoperative sutures. The complex application of diet therapy and the basic treatmentfor dystrophic joint diseases and the rehabilitation measures of the postoperative period were shown to be effective. Inpatients, joint pain and pain index decreased, the fragility of nails and hair was reduced, the microcirculation of the nail bedimproved, and the healing time of the surgical sutures decreased. The consistency of quality indicators and consumerperformance was ensured by production certifications for the developed products within the requirements of internationalstandards of the ISO 9001 and 22000 series and GMP rules.
