Diagnostic Capability of Intra-Articular Injections for Femoroacetabular Impingement Syndrome: A Systematic Review.

OBJECTIVE: To review and critically appraise available literature concerning the diagnostic capability of intra-articular injections for femoroacetabular impingement (FAI) syndrome. DESIGN: Systematic review. SETTING: N/A. PARTICIPANTS: N/A. INTERVENTIONS: N/A. MAIN OUTCOME MEASURES: Studies assessing pain relief following intra-articular injections for the diagnosis of FAI syndrome, compared with arthroscopy as diagnostic reference standard, were considered eligible. Searches were performed across 8 databases, and the risk of bias was evaluated through the Quality Assessment of Diagnostic Accuracy Studies tool. RESULTS: From 489 articles identified, 4 were included for analysis. Intra-articular injections were composed of anesthetic agents (such as lidocaine, bupivacaine, and ropivacaine), combined or not with corticosteroids (triamcinolone and betamethasone). All studies were judged as "at risk of bias", and a substantial heterogeneity was found considering assessment methods and pain relief thresholds for a positive response to intra-articular injections. Overall, 2 studies reported that intra-articular injections presented a high accuracy in determining the presence of FAI syndrome. However, the remaining 2 studies indicated that intra-articular injections might present restricted diagnostic capability to discriminate FAI syndrome from healthy individuals or those with other hip pathologies. CONCLUSIONS: Based on limited evidence, the diagnostic capability of intra-articular injections for FAI syndrome cannot be supported. It remains unclear which pain relief thresholds are related to a higher diagnostic capability. The combination of anesthetics with corticosteroids should also be further explored, including multiple pain assessments for evaluation of prolonged effects.

Does response to preoperative intra-articular anesthetic injections predict outcomes of femoroacetabular impingement syndrome?

INTRODUCTION: Some patients with femoroacetabular impingement syndrome (FAIS) who undergo surgery do not show satisfactory outcomes. Reliable tests that can inform prognosis of FAIS surgery are needed for optimized indications and contraindications to surgery. We aimed to review and critically appraise available literature on the capability of patient response to preoperative intra-articular anesthetic injections (PIAI) to predict post-surgical outcomes in patients with FAIS. MATERIALS AND METHODS: This study was conducted in accordance with the PRISMA statement. Studies that assessed the patient pain response to PIAI and post-surgical outcomes in patients with FAIS were considered eligible. Study selection and data collection were performed by three independent reviewers. Main outcomes evaluated were those measured by hip outcome scales often used in assessing postoperative pain and functional recovery, such as the modified Harris Hip Score (mHHS) and international Hip Outcome Tool (iHOT). The likelihood ratio of achieving satisfactory postoperative outcomes at the mHHS (LHR) was extracted or calculated-for patients with significant response to PIAI and for those without a significant response to PIAI. The risk of bias was assessed using the Quality In Prognosis Studies (QUIPS) tool. RESULTS: Six studies were considered eligible for analysis. Five studies indicated that patient response to PIAI are associated to surgical outcomes for patients with FAIS, with a greater reduction in pain typically indicating a better surgical outcome. Additionally, the LHR ranged from 1.15 to 1.92 for patients with significant response to PIAI (I2 = 90.6%). For patients without a significant response, the LHR ranged from 0.18 to 0.65 (I2 = 87.5). An overall high risk of bias was observed for all studies included in the analysis. Study attrition, the prognostic factor measurement and the presence of confounding factors were the main sources of bias. CONCLUSIONS: Greater reductions in pain with preoperative intra-articular anesthetic injections were found to be associated to better outcomes after FAIS surgery, but all available studies contain a high risk of bias.

Effects of total knee arthroplasty for primary knee osteoarthritis on postural balance: A systematic review.

BACKGROUND: Knee osteoarthritis is often related to physical function impairment. Although total knee arthroplasty is considered effective for advanced cases of knee osteoarthritis, its effects on postural balance is a topic of debate. RESEARCH QUESTION: What are the effects of total knee arthroplasty for primary knee osteoarthritis on postural balance compared to preoperative status and/or to healthy controls?. METHODS: Longitudinal studies (with more than 1-month follow-up) assessing postural balance measures (either clinical-based such as balance scales or laboratory-based such as postural sway) were considered eligible and selected in a 2-phase process. Six main electronic databases were searched, complemented by 3 grey literature sources. The risk of bias was evaluated using the Joanna Briggs Institute Critical Appraisal Tools. RESULTS: A total of 19 studies were included for qualitative synthesis, of which 14 had low and 5 had a moderate risk of bias. The follow-up period ranged from 1-24 months. Most studies (n = 11) presented comparisons to preoperative status only. From these, 7 studies reported relevant improvements in postural balance, 2 reported partial improvements, and 2 no improvements. The remaining studies (n = 8) presented comparisons to healthy controls and, although improvements following total knee arthroplasty were consistently observed, only one study reported postural balance measures comparable to that of controls. CONCLUSIONS: The majority of studies reported relevant improvements (especially in clinical-based measures) compared to preoperative evaluations, although inconsistencies were found possibly due to variability in studies' populations, assessment tools, and follow-up times. Despite this, persistent deficits in postural balance were commonly observed when compared to healthy controls. SIGNIFICANCE: This evidence synthesis could better inform clinicians and researchers about the therapeutic effects and limitations of total knee arthroplasty concerning postural balance. Standardization of assessment tools is recommended to strengthen the certainty of cumulative evidence.

Trauma do nervo facial e terapias de tratamento / Facial nerve trauma and treatment therapies

Os traumatismos bucomaxilofaciais, associados com as fraturas do osso temporal e lacerações na face, muitas vezes acabam causando algumas lesões em nervos periféricos, em específico, o nervo facial. Quando lesionado, o VII par craniano pode comprometer profundamente a vida dos pacientes, tanto com alterações fisiológicas significativas, quanto alterações psicológicas. O tratamento dessas lesões, geralmente é cirúrgico; no entanto, os resultados muitas vezes ainda são insatisfatórios. Com o intuito de aprimorar as técnicas cirúrgicas no tratamento das lesões aos nervos periféricos, muitos estudos têm sidos realizados pela engenharia de tecidos com o objetivo de desenvolver biomateriais associados com fatores neuroindutores, principalmente nas lesões nervosas em que há perda de substância. O estudo desses biomateriais parece ser bastante promissor, tornando-se uma fonte viável em substituição ao enxerto autólogo, que; embora seja o "padrão ouro", ainda apresenta limitações. Sendo assim, esse artigo consiste de uma revisão de literatura livre, pelo pubmed, sobre trauma de nervo facial e alternativas de tratamento.

Buccomaxillofacial trauma, associated with temporal bone fractures and lacerations on the face, often end up causing some lesions on peripheral nerves, specifically the facial nerve. When injured, the VII cranial torque can profoundly compromise patients' lives, both with significant physiological changes and psychological changes. The treatment of these lesions is usually surgical; However, the results are often still unsatisfactory. In order to improve surgical techniques in the treatment of peripheral nerve injuries, many studies have been carried out by tissue engineering in order to develop biomaterials associated with neuroindustrial factors, especially in nerve lesions in which there is loss of substance. The study of these biomaterials seems to be quite promising, becoming a viable source in replacement of the autologous graft, which; Although it is the "gold standard", still has limitations. Thus, this article consists of a review of free literature, by pubmed, on facial nerve trauma and treatment alternatives.

Balance and quality of life after total knee arthroplasty / Equilíbrio e qualidade de vida após artroplastia total de joelho

ABSTRACT Objective: To evaluate the change in balance and quality of life in patients undergoing total knee arthroplasty for primary gonarthrosis. Method: Patients aged 60 years or older were evaluated in relation to the balance and quality of life before total knee arthroplasty and six months after surgery. To assess balance, this study used the Motor Scale Test for the Elderly; quality of life was assessed using the Western Ontario and McMaster Universities Osteoarthritis Index questionnaire and the Short Form Health Survey. A control group consisting of healthy adults, age- and gender-paired, was used to compare the balance after surgery results. Results: Twenty-eight patients completed the study, of a total of 37 arthroplasties. The mean age was 70.18 ± 6.17 years. All variables were statistically significant (p ≤ 0.05) for improved balance and quality of life after arthroplasty. It was observed that, after knee arthroplasty, the level of balance does not reach that expected for healthy individuals (p ≤ 0.05). Conclusion: Total knee arthroplasty is effective at improving balance six months after surgery, as well as all domains of quality of life. However, it is not able to restore balance to a level comparable to that of healthy individuals.

RESUMO Objetivo: Avaliar o equilíbrio e a qualidade de vida em pacientes submetidos a artroplastia total do joelho por gonartrose primária. Método: Pacientes com 60 anos ou mais foram avaliados em relação ao equilíbrio e à qualidade de vida antes da artroplastia total de joelho e seis meses após a cirurgia. Para avaliar o equilíbrio, foi usado o teste da Escala Motora para a Terceira Idade; para avaliar a qualidade de vida, foram usados os questionários Western Ontario and McMaster Universities Osteoarthritis Index e Short Form Health Survey. Um grupo controle de indivíduos saudáveis, pareado por idade e gênero, foi usado para comparação dos níveis de equilíbrio do grupo em estudo após a cirurgia. Resultados: Completaram o estudo 28 pacientes, em 37 artroplastias. A média de idade foi de 70,18 ± 6,17 anos. Em todas as variáveis analisadas, observou-se significância estatística (p ≤ 0,05) para melhoria do equilíbrio e da qualidade de vida após a artroplastia. Observou-se que, após artroplastia do joelho, o nível de equilíbrio não alcança o nível esperado para indivíduos saudáveis (p ≤ 0,05). Conclusão: A artroplastia total de joelho é capaz de melhorar o equilíbrio seis meses após a cirurgia, bem como todos os domínios da qualidade de vida. No entanto, não é capaz de restaurar o equilíbrio comparável àquele dos indivíduos saudáveis.
