An Assessment of Ankle Function, Oxidative Damage, and Inflammatory Factor Levels in Minimally Invasive Ankle Joint Fusion Surgery for the Treatment of Traumatic Ankle Osteoarthritis

SUMMARY: Traumatic ankle osteoarthritis is a degenerative condition resulting from traumatic injuries. The objective of this study was to evaluate the impact of minimally invasive ankle joint fusion surgery on ankle function, oxidative damage, and inflammatory factor levels in traumatic ankle osteoarthritis patients. A total of 112 traumatic ankle osteoarthritis patients treated in our hospital from January 2022 to January 2023 were enrolled. They were randomly rolled into a control group (Group C) and an experimental group (Group E), with the former undergoing conventional open ankle joint fusion surgery and the latter receiving minimally invasive ankle joint fusion surgery. A comparison was made between the two groups based on American Orthopedic Foot and Ankle Society (AOFAS), bony fusion rates, and visual analog scale (VAS) scores at pre-operation, and at 1, 2, and 3 months post-operation. Additionally, serum oxidative damage indicators and inflammatory factor levels were measured to evaluate the recovery effects in both groups. Relative to Group C, Group E showed drastically increased AOFAS scores and bony fusion rates (P<0.05), as well as greatly decreased VAS scores (P<0.05). Moreover, Group E exhibited more pronounced improvements in oxidative damage indicators and inflammatory factors versus Group C (P<0.05). Minimally invasive ankle joint fusion surgery drastically improves ankle function in traumatic ankle osteoarthritis patients and reduces levels of oxidative damage and inflammatory response. This provides an important clinical treatment option.

La osteoartritis traumática del tobillo es una afección degenerativa resultante de lesiones traumáticas. El objetivo de este estudio fue evaluar el impacto de la cirugía mínimamente invasiva de fusión de la articulación talocrural sobre la función del tobillo, el daño oxidativo y los niveles de factor inflamatorio en pacientes con osteoartritis traumática del tobillo. Se inscribieron un total de 112 pacientes con artrosis traumática de tobillo tratados en nuestro hospital desde enero de 2022 hasta enero de 2023. Fueron divididos aleatoriamente en un grupo de control (Grupo C) y un grupo experimental (Grupo E), donde el primero se sometió a una cirugía de fusión de la articulación talocrural abierta convencional y el segundo recibió una cirugía de fusión de la articulación talocrural mínimamente invasiva. Se realizó una comparación entre los dos grupos según la Sociedad Estadounidense de Ortopedia de Pie y Tobillo (AOFAS), las tasas de fusión ósea y las puntuaciones de la escala visual analógica (EVA) antes de la operación y 1, 2 y 3 meses después de la operación. Además, se midieron los indicadores de daño oxidativo sérico y los niveles de factor inflamatorio para evaluar los efectos de la recuperación en ambos grupos. En relación con el grupo C, el grupo E mostró puntuaciones AOFAS y tasas de fusión ósea drásticamente aumentadas (P <0,05), así como puntuaciones VAS muy disminuidas (P <0,05). Además, el grupo E exhibió mejoras más pronunciadas en los indicadores de daño oxidativo y factores inflamatorios en comparación con el grupo C (P <0,05). La cirugía de fusión de la articulación talocrural mínimamente invasiva mejora drásticamente la función del tobillo en pacientes con osteoartritis traumática del tobillo y reduce los niveles de daño oxidativo y la respuesta inflamatoria. Esto proporciona una importante opción de tratamiento clínico.

Chinese Medicines Treat Rheumatoid Arthritis via Gut-joint Axis： A Review / 中国实验方剂学杂志

Rheumatoid arthritis （RA） is a systemic autoimmune disease with local joint pain as the main clinical manifestation. It is one of the diseases specifically responding to traditional Chinese medicine （TCM）. The occurrence of RA is not only related to innate factors like genetic disorder but also associated with environmental factors， such as diets and microbial infection. The intestine， a vital human organ with digestive and immune functions， is a place where microorganisms colonize and exert intestinal metabolism-improving， barrier-protecting， and immunomodulatory effects. As the research on the onset and treatment of RA is deepening， the potential relationship of intestinal structural and functional abnormalities with the pathogenesis and progression of RA has been revealed. As clinical and experimental studies indicated， joint inflammation coexists with the impaired barrier function， imbalanced immune cells， and disordered gut microbiota. The theory of the gut-joint axis in the pathogenesis， progression， and treatment of RA is highly consistent with the holistic view in TCM. The recent pharmacological studies have shown that Chinese medicine prescriptions and active components can inhibit inflammation， protect joints， and maintain the intestinal function. This article summarizes the basic connotation of the gut-joint axis in RA and the mechanism by which TCM protect the intestinal barrier and modulate the immunity by regulating the gut microbiota structure and improving microbial metabolism in the treatment of RA. This review gives insights into the future research on the gut-joint axis in RA.

Expert Consensus on Clinical Diseases Responding Specifically to Traditional Chinese Medicine：Fibromyalgia Syndrome / 中国实验方剂学杂志

Fibromyalgia syndrome （FMS） is a refractory， chronic non-articular rheumatic disease characterized by widespread pain throughout the body， for which there are no satisfactory therapeutic drugs or options. There are rich Chinese medical therapies， and some non-drug therapies， such as acupuncture， Tai Chi， and Ba-Duan-Jin， have shown satisfactory efficacy and safety and definite advantages of simultaneously adjusting mind and body. FMS is taken as a disease responding specifically to traditional Chinese medicine （TCM） by the National Administration of Traditional Chinese Medicine in 2018. In order to clarify the research progress in FMS and the clinical advantages of TCM/integrated Chinese and Western medicine， the China Academy of Chinese Medicine organized a seminar for nearly 20 experts in Chinese and Western medicine， including rheumatology， psychology， acupuncture and moxibustion， and encephalopathy， with the topic of difficulties in clinical diagnosis and treatment of FMS and advantages of TCM and Western medicine. The recommendations were reached on the difficulties in early diagnosis and solutions of FMS， mitigation of common non-specific symptoms， preferential analgesic therapy， TCM pathogenesis and treatment advantages， and direction of treatment with integrated Chinese and Western medicine. FMS is currently facing the triple dilemma of low early correct diagnosis， poor patient participation， and unsatisfactory benefit from pure Western medicine treatment. To solve the above problems， this paper suggests that rheumatologists should serve as the main diagnostic force of this disease， and they should improve patient participation in treatment decision-making， implement exercise therapy， and fully utilize the holistic and multidimensional features of TCM， which is effective in alleviating pain， improving mood， and decreasing adverse events. In addition， it is suggested that FMS treatment should rely on both TCM and Western medicine and adopt multidisciplinary joint treatment， which is expected to improve the standard of diagnosis and treatment of FMS in China.

Evaluation of condylar position in patients with malocclusion and changes in condylar position before and after orthodontic treatment using cone beam computed tomography / 口腔疾病防治

@#The functional health and stability of the oral and maxillofacial system is one of the basic goals of orthodontic treatment. Currently, it is believed that, in general, the condyle is located in the center of the joint fossa when the mandible is in an intercuspal position (ICP) in healthy normal people. At this time, the function of the temporomandibular joint (TMJ) is stable. Due to orthodontic tooth movement and subsequent occlusal changes, patients with malocclusion may experience related remodeling of the temporomandibular joint, especially changes in the position of the condyle. The position of the mandibular condyle is traditionally evaluated using a condylar position indicator. However, this method lacks consistency in obtaining condylar position changes. In recent years, in the clinical application of orthodontic treatment, cone beam computed tomography (CBCT) has become the first choice for examination. CBCT can accurately measure the interarticular space and determine changes in condylar position. This article reviews the CBCT assessment of condylar position and related research on condylar position changes in patients with malocclusion before and after orthodontic treatment. The literature review results indicate that there are differences in the condylar position of patients with different malocclusions, and the condylar position may also change before and after orthodontic treatment. With a lower radiation dose, CBCT has higher accuracy in evaluating the condylar position in patients with malocclusion who undergo orthodontic treatment, thus promoting further study of the mechanism of condylar position changes in patients with malocclusion in the future and providing more accurate and personalized guidance for patient treatment.

Objective To investigate the morphological typing and clinical significance of the distal tibiofibular syndesmosis fibular notch based on CT images. Methods According to the inclusion and exclusion ceiteria‚ the imaging data of patients undergoing ankle joint CT examination were analyzed‚ and the inferior tibiofibular joint fibula notch was classified according to the morphological characteristics. The measurements included 8 distances. There were 123 males and 102 females‚ all of whom were Han nationality‚ aged 18-60 years old. Results Retrospectively analyzed the result of 225 patients from December 2013 to December 2022. The distal tibiofibular syndesmosis fibular notch was divided into four types according to morphological characteristics‚ C-shaped (50. 67%)‚ V-shaped (26. 67%)‚ flat-shaped (15. 11%) and L-shaped (7. 56%). The angle between the anterior and posterior facets of the flat shape (145. 56 ± 9. 25)° was the largest and the angle between the anterior and posterior facets of the L shape (125. 07 ± 13. 54)° was the smallest(P< 0. 05); the depth of the notch in the flat shape (3. 11 ± 0. 83) mm was the smallest and in the L shape (4. 47±1. 11) mm was the largest(P<0. 05);The posterior facet length (13. 06 ± 3. 56) mm and anterior tibiofibular gap (3. 83±1. 49) mm on left were larger than on the right side (P<0. 05); The posterior facet length (13. 36 ± 3. 46) mm‚ fibular notch depth (3. 93 ± 1. 10) mm and vertical distance of tibiofibular overlap (9. 10 ± 2. 55) mm larger in men than in women (P<0. 05). Conclusion In this study‚ the data related to the inferior tibiofibular syndesmosis notch were measured and divided into four types according to the shape. The flat inferior tibiofibular syndesmosis notch is more likely to have chronic ankle instability‚ and the fibula is more likely to move forward during anatomical reduction. The inferior tibiofibular syndesmosis of L-shaped and C-shaped notches is more prone to posterior displacement of fibula or poor rotation reduction during anatomical reduction.

Facial representation of paroxysmal hemicrania and associated temporomandibular disorder: a case report / Hemicrania paroxística com representação na face e associação com disfunção temporomandibular: relato de caso

ABSTRACT Paroxysmal Hemicrania is a trigeminal autonomic cephalalgia described as a severe and strictly unilateral pain, which occurs in paroxysms at orbital, supraorbital and/ or temporal region. A 45-year-old woman presented to an orofacial pain specialist reporting severe, burning, throbbing, strictly right-sided headache associated to ipsilateral autonomic symptoms and orofacial pain. The pain was perceived on the maxillary region followed by pain spread to the head. Interdisciplinary evaluation, along with absolute responsiveness to indomethacin and normal Brain Magnetic Resonance imaging, led to the diagnosis of primary Episodic paroxysmal hemicrania with facial representation and myofascial pain of masticatory muscles. Dentists should be aware of paroxysmal hemicrania with facial representation and the possibility of temporomandibular disorder coexistence, in order to avoid misdiagnosis and inadequate management. Paroxysmal hemicrania may be first perceived on the face and may be associated with interparoxysmal pain. In these cases, efficient anamnesis and clinical evaluation followed by interdisciplinary approach is needed.

RESUMO A Hemicrania Paroxística é uma cefalalgia autonômica trigeminal descrita como uma dor severa e estritamente unilateral, que ocorre em paroxismos na região orbital, supraorbital e/ou temporal. Uma mulher de 45 anos de idade apresentou-se a um especialista em dor orofacial, referindo uma cefaleia intensa, ardente, latejante, estritamente do lado direito, associada a sintomas autonómicos ipsilaterais e dor orofacial. A dor era sentida na região maxilar, seguida de dor que se estendia à cabeça. A avaliação interdisciplinar, aliada à resposta absoluta à indometacina e à normalidade em ressonância magnética cerebral, levou ao diagnóstico de hemicrania paroxística episódica primária com representação facial e dor miofascial dos músculos mastigatórios. Os médicos dentistas devem estar atentos à hemicrania paroxística com representação facial e à possibilidade de coexistência de Disfunção Temporomandibular, de modo a evitar diagnósticos incorretos e um tratamento inadequado. A hemicrania paroxística pode ser percebida inicialmente na face e pode estar associada à dor interparoxística. Nesses casos, é necessária uma anamnese e avaliação clínica eficientes, seguidas de abordagem interdisciplinar.

Imaging findings of acute calcific periarthritis, with emphasis on magnetic resonance imaging: pictorial essay / Achados de imagem da periartrite cálcica aguda, com ênfase na ressonância magnética: ensaio iconográfico

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.

Bone erosions and joint damage caused by chikungunya virus: a systematic review

ABSTRACT Background: Chikungunya fever is an emerging global infection transmitted by Aedes mosquitoes that manifests as an acute febrile illness with joint pain and can lead to chronic arthritis. The mechanism underlying chronic joint damage remains unclear; however, chronic chikungunya arthritis shares similarities with rheumatoid arthritis. Disease-modifying antirheumatic drugs have revolutionized rheumatoid arthritis treatment by preventing joint damage. However, the role of these therapies in chronic chikungunya arthritis has not been determined. We conducted a systematic review to evaluate the burden of joint structural damage in chronic chikungunya arthritis to help to define the role of disease-modifying therapy in this disease. Methods: This systematic review included retrospective and prospective studies, trials, and case reports evaluating joint damage caused by chikungunya virus. Various databases were searched without any date or language restrictions. Study selection was conducted independently by two researchers, and data were extracted from the articles selected. Results: A total of 108 studies were initially evaluated, with 8 meeting the inclusion criteria. Longitudinal studies have reported persistent joint pain from chikungunya infection and the progression of radiographic joint damage up to 13 years post-infection. Joint imaging revealed synovial inflammation, bone erosion, and cartilage destruction in patients with chronic chikungunya arthritis. Conclusions: Few studies have addressed chikungunya-induced joint damage, limiting our understanding of chronic chikungunya arthritis. Nevertheless, chronic chikungunya arthritis has similarities to rheumatoid arthritis. The success of early disease-modifying antirheumatic drug therapy in rheumatoid arthritis underscores the need for comprehensive research on its role in chikungunya arthritis.

Does the elbow position change the handgrip strength in Parkinson's disease? / A posição do cotovelo altera a força de preensão manual na doença de Parkinson?

Abstract The flexed elbow is a standardization position on the handgrip strength test, however the literature shows divergence in the values obtained from extended elbow. The aim of this study was to verify if there is such difference in people with Parkinson's disease. Cross-sectional study. Thirty-one elderly individuals with clinical diagnosis of Parkinson's disease, performed 2 handgrip tests, first with extended elbow and second with flexed elbow, with 48 hours of interval. There was not significantly different between positions for handgrip strength (p > 0.05). As well as, the effect size was insignificant (d < 0.19). The main results indicate there was no significant difference between the flexed and the extended protocol, the effect size was negative and very small, it shows there is no clinical effect. Since, there are no difference between elbow positions, The American Society of Hand Therapists standardized position is recommended for testing of handgrip strength.

Resumo O cotovelo flexionado é uma posição padronizada no teste de força de preensão manual, no entanto, a literatura mostra divergências nos valores obtidos com o cotovelo estendido. O objetivo deste estudo foi verificar se existe tal diferença em pessoas com a doença de Parkinson. Estudo transversal. Trinta e um idosos com diagnóstico clínico da doença de Parkinson realizaram 2 testes de preensão manual, o primeiro com o cotovelo estendido e o segundo com o cotovelo flexionado, com intervalo de 48 horas. Não houve diferença significativa entre as posições para a força de preensão manual (p > 0,05). Além disso, o tamanho do efeito foi insignificante (d < 0,19). Os principais resultados indicam que não houve diferença significativa entre o protocolo flexionado e o estendido, o tamanho do efeito foi negativo e muito pequeno, o que mostra que não há efeito clínico. Portanto, não há diferença entre as posições do cotovelo, recomenda-se a posição padronizada da Sociedade Americana de Terapeutas de Mão para o teste de força de preensão manual.

Minimally Invasive Tibiotalocalcaneal Arthrodesis with Blocked Retrograde Intramedullary Nail - Report of Three Cases / Artrodese tibiotalocalcaneana minimamente invasiva com haste intramedular retrógrada bloqueada - Relato de três casos

Abstract Ankle osteoarthritis (AOA) is associated with pain and variable functional limitation, demanding clinical treatment and possible surgical indication when conservative measures are ineffective - arthrodesis has been the procedure of choice, because it reduces pain, restores joint alignment and makes the segment stable, preserving gait. The present study reports 3 cases (3 ankles) of male patients between 49 and 63 years old, with secondary AOA, preoperative American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale (AOFAS AHS) of 27 to 39 points, treated by minimally invasive tibiotalocalcaneal arthrodesis using blocked retrograde intramedullary nail. Hospital stay was of 1 day, and the patients were authorized for immediate loading with removable ambulation orthotics, as tolerated. The physical therapy treatment, introduced since hospitalization, was maintained, prioritizing gait training, strength gain, and proprioception. Clinical and radiographic follow-up was performed at weeks 1, 2, 6, 12 and 24. After evidence of consolidation (between the 6th and 10th weeks), the orthotics were removed. One patient complained of pain in the immediate postoperative period and, at the end of the 1st year, only one patient presented pain during rehabilitation, which was completely resolved with analgesics. Currently, the patients do not present complaints, returning to activities without restrictions - one of them, to the practice of soccer and rappelling. The postoperative AOFAS AHS was from 68 to 86 points.

Resumo A osteoartrite do tornozelo (OAT) está associada a quadro álgico e limitação funcional variável, demandando tratamento clínico e eventual indicação cirúrgica quando as medidas conservadoras são inefetivas - a artrodese tem sido o procedimento de escolha, por reduzir a dor, restaurar o alinhamento articular e tornar o segmento estável, preservando a marcha. O presente estudo relata 3 casos (3 tornozelos) de pacientes do sexo masculino, com entre 49 e 63 anos de idade, portadores de OAT secundária, American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale (AOFAS AHS, na sigla em inglês) pré-operatória de 27 a 39 pontos, tratados mediante artrodese tibiotalocalcaneana minimamente invasiva utilizando haste intramedular retrógrada bloqueada. A permanência hospitalar foi de 1 dia, e os pacientes foram autorizados para carga imediata com órteses removíveis para deambulação, conforme tolerado. O tratamento fisioterápico, introduzido desde o internamento, foi mantido, priorizando-se treino de marcha, ganho de força e propriocepção. Foi realizado acompanhamento clínico e radiográfico nas semanas 1, 2, 6, 12 e 24. Após evidências de consolidação (entre a 6ª e a 10ª semanas), as órteses foram retiradas. Um paciente queixou-se de dor no pós-operatório imediato e, ao final do 1° ano, apenas 1 paciente apresentou dor durante a reabilitação, resolvida completamente com analgésicos. Atualmente, os pacientes não apresentam queixas, retornando às atividades sem restrições - um deles, à prática de futebol e rapel. A AOFAS AHS pós-operatória foi de 68 a 86 pontos.

Must a Knee with Anterior Cruciate Ligament Deficiency and High-grade Pivot Shift Test Present an Increase in Internal Rotation? / Um joelho com deficiência de ligamento cruzado anterior e alto grau no teste de pivot shift deve apresentar aumento de rotação interna?

Abstract Objective: Rupture of the anterior cruciate ligament (ACL) is one of the most common injuries in athletes and is often associated with damage to anterolateral structures. This combination of injuries presents itself clinically as a high-grade pivot shift test. The hypothesis of this study is that patients with ACL deficiency and high-grade pivot shift test should have an increased internal knee rotation. Methods: Twenty-two patients were tested. After effective spinal anesthesia, two tests were performed with the patient in supine position. First, the bilateral pivot shift test was performed manually, and its grade was recorded. Then, with the knee flexed to 90 degrees, the examiner drew the projection of the foot in a neutral position and in maximum internal rotation, and the angle of internal rotation was measured from the axes built between the central point of the heel and the hallux. Results: In the ACL-deficient knee, it was observed that there is a statistically significant average internal rotation (IR) delta of 10.5 degrees between the groups when not adjusted for age, and 10.6 degrees when adjusted for age. Conclusions: Knees with ACL deficiency and with pivot shift test grade I do not show increased internal rotation in relation to knees with intact ACL. Knees with ACL deficiency and with pivot shift test grades II and III show increased internal rotation in comparison to healthy knees.

Resumo Objetivo: A ruptura do ligamento cruzado anterior (LCA) é uma das lesões mais comuns em atletas e está frequentemente associada a danos nas estruturas anterolaterais. Esta combinação de lesões apresenta-se clinicamente como um teste de pivot shift de alto grau. A hipótese deste estudo é que pacientes com deficiência de LCA e teste de pivot shift de alto grau tenham aumento da rotação interna (RI) do joelho. Métodos: Vinte e dois pacientes foram testados. Após raquianestesia efetiva, foram realizados dois testes com o paciente em posição supina. Primeiro, o teste de pivot shift bilateral foi realizado manualmente e seu grau foi registrado. Em seguida, com o joelho flexionado a 90 graus, o examinador traçou a projeção do pé em posição neutra e em RI máxima e mediu o ângulo de RI a partir dos eixos construídos entre o ponto central do calcanhar e o hálux. Resultados: Joelhos com deficiência de LCA apresentam delta da RI média estatisticamente significativo de 10,5 graus entre os grupos sem ajuste de idade e de 10,6 graus com ajuste de idade. Conclusões: Joelhos com deficiência do LCA e teste de pivot shift de grau I não apresentam aumento da RI em relação aos joelhos com LCA íntegro. Joelhos com deficiência do LCA e teste de pivot shift de graus II e III apresentam RI em comparação aos joelhos saudáveis.
