Evolución clínica en pacientes con síndrome del túnel carpiano tratados con ultrasonido o infiltración con corticoesteroides / Clinical Evolution in Patients with Carpal Tunnel Syndrome Treated with Ultrasound or Corticosteroid Infiltration

Introducción. El Síndrome del túnel carpiano es la neuropatía periférica compresiva más común de la extremidad superior, que se produce por la compresión del nervio mediano. Los casos leves y moderados pueden tratarse con métodos conservadores como ultrasonido terapéutico o infiltración con corticoesteroides. Objetivo. Describir la evolución clínica de pacientes con síndrome de túnel carpiano tratados con terapia por ultrasonido e infiltración de corticoesteroides. Metodología. Ensayo clínico abierto, en pacientes con síndrome del túnel carpiano leve y moderado, que consultaron del 1 de octubre 2021 al 30 de mayo 2022. Se formaron dos grupos; el que recibió tratamiento con ultrasonido con 12 casos y el grupo tratado con infiltración con corticoesteroides con seis casos. Ambos grupos fueron intervenidos en la consulta inicial, y luego, en las cuatro y ocho semanas posteriores al inicio del tratamiento. Resultados. Se muestran los resultados descriptivos relacionados con la intensidad de dolor, valorada con la Escala Visual Numérica, la infiltración obtuvo dos casos sin dolor y cuatro con dolor moderado, contrario a ultrasonido que se mantuvo con cuatro casos leves, tres moderados y cinco intensos. En los síntomas, la infiltración redujo el número de casos en cuatro de los síntomas estudiados, en cambio el ultrasonido únicamente en dos. En severidad, valorada con el cuestionario de Boston para túnel carpal, con infiltración se obtuvieron dos casos asintomáticos y ninguno con ultrasonido. Respecto a los signos clínicos, el signo de Tinel desapareció en cuatro casos en ambos grupos, mientras que signo de Phalen desapareció en cuatro casos en ultrasonido y dos en infiltración. Conclusión. En intensidad de dolor y grado de severidad, la infiltración generó casos asintomáticos y redujo mayor cantidad de síntomas que el ultrasonido. Ambos tratamientos disminuyeron la presencia de signos clínicos

Introduction. Carpal tunnel syndrome is the most common compressive peripheral neuropathy of the upper extremity, which is caused by compression of the median nerve. Mild and moderate cases can be treated with conservative methods such as therapeutic ultrasound or corticosteroid infiltration. Objective. To describe the clinical evolution of patients with carpal tunnel syndrome treated with ultrasound therapy and corticosteroid infiltration. Methodology. A prospective open clinical trial was conducted in patients with mild and moderate carpal tunnel syndrome who consulted from October 1, 2021 to May 30, 2022. Two groups were formed: the group that received ultrasound treatment with 12 cases and the group treated with corticosteroid infiltration with six cases. Both groups were treated at the initial consultation and then at four and eight weeks after the start of treatment. Results. The descriptive results related to the intensity of pain, evaluated with the Visual Numeric Scale, are shown. Infiltration obtained two cases without pain and four with moderate pain, contrary to ultrasound which was maintained with four mild, three moderate and five intense cases. In symptoms, infiltration reduced the number of cases in four of the symptoms studied, while ultrasound reduced the number of cases in only two. In severity, assessed with the Boston carpal tunnel questionnaire, with infiltration, there were two asymptomatic cases and none with ultrasound. Regarding clinical signs, Tinel's sign disappeared in four cases in both groups, while Phalen's sign disappeared in four cases in ultrasound and two in infiltration. Conclusion. Infiltration produced asymptomatic patients and reduced more symptoms than ultrasonography in terms of pain intensity and severity. Clinical symptoms were less common with both treatments.

Usefulness of the Phalen Test and the Tinel Sign in the Prognosis and the Impact on Quality of Life of Patients with Carpal Tunnel Syndrome Undergoing Classical Open Carpal Tunnel Release / Utilidade do teste de Phalen e do sinal de Tinel no prognóstico e o impacto na qualidade de vida de pacientes com síndrome do túnel do carpo submetidos a liberação aberta clássica do túnel do carpo

Abstract Objective: To evaluate the usefulness of the Phalen test and the Tinel sign in the prognosis and the impact on quality of life in the clinical course of patients with carpal tunnel syndrome undergoing surgical treatment through the traditional open approach. Methods: The present is a cohort study on prognosis. We included 115 patients with high probability of receiving a clinical diagnosis of carpal tunnel syndrome with indication for surgical treatment. All patients underwent the Phalen test and Tinel sign and answered the Boston Carpal Tunnel Questionnaire before and after the surgical treatment. Results: The estimates for the probability of the time until remission of the Phalen test at 2, 4 and 16 weeks postoperatively were of 3.54% (95% confidence interval [95% CI]: 1.16%-8.17%), 0.88% (95%CI: 0.08%-4.38%) and 0.88% (95%CI: 0.08% to 4.38%) respectively, and, for the Tinel sign, they were of 12.39% (95%CI: 7.13%-19.18%), 4.42% (95%CI : 1.65%-9.36%) and 2.65% (95%CI : 0.70%-6.94%) respectively. There was a reduction in the postoperative score on the Boston Carpal Tunnel Questionnaire of 1.8 points for symptom severity (p < 0.001) and of 1.6 points for functional status (p < 0.001). Conclusion: Phalen test remission was earlier than that of the Tinel sign, but, when performed as of the second postoperative week, they were prognostic factors favorable to the clinical course, with improved quality of life.

Resumo Objetivo: Avaliar a utilidade do teste de Phalen e do sinal de Tinel no prognóstico e o impacto na qualidade de vida no curso clínico de pacientes com síndrome do túnel do carpo submetidos ao tratamento cirúrgico por via aberta clássica. Métodos: Trata-se de um estudo de coorte sobre prognóstico. Foram incluídos 115 pacientes com alta probabilidade de diagnóstico clínico de síndrome do túnel do carpo com indicação de tratamento cirúrgico. Todos os pacientes foram submetidos ao teste de Phalen e ao sinal de Tinel, e responderam ao questionário de Boston antes e depois do tratamento cirúrgico. Resultados: As estimativas de probabilidade do tempo até a remissão do teste de Phalen em 2, 4 e 16 semanas pós-operatórias foram de 3,54% (intervalo de confiança de 95% [IC95%]:1,16%-8,17%), 0,88% (IC95%: 0,08%-4,38%) e 0,88% (IC95%: 0,08%-4,38%), respectivamente, e, do sinal de Tinel, foram de 12,39% (IC95%: 7,13%-19,18%), 4,42% (IC95%: 1,65%-9,36%) e 2,65% (IC95%: 0,70%-6,94%), respectivamente. Na pontuação pós-operatória no Questionário de Boston, houve redução de 1,8 ponto para a gravidade dos sintomas (p < 0,001), e de 1,6 ponto para o estado funcional (p < 0,001). Conclusão: A remissão do teste de Phalen foi mais precoce do que a do sinal de Tinel, mas, realizados a partir da segunda semana de evolução pós-operatória, esses testes foram fatores prognósticos favoráveis ao curso clínico, com melhora da qualidade de vida.

Application of modified mucogingival surgery in the treatment of gingival recession / 口腔疾病防治

@#With the increasing demand for beauty, the treatment of gingival recession has become a common request among patients. Clinically, gingival recession is mainly treated by surgery. The common surgical methods include free gingival grafting, pedicled flap technology and double flap technology (subepithelial connective tissue transplantation combined with coronally advanced flaps). If patients with indications are selected, satisfactory surgical results will be obtained. However, there are still some shortcomings in the above mentioned methods, such as the root coverage effect not being satisfactory. In recent years, researchers have put forward some improved schemes to minimize the shortcomings of the above methods to treat different degrees of gingival recession. A gingival unit graft containing gingival papilla and free gingiva can improve the blood supply of the recipient area and improve the effect of root coverage. It can obtain better root coverage for slight retraction, widening of the angular gingiva and deepening of the vestibular sulcus, but there may be issues with inconsistent color and shape of the gingiva after surgery, as well as poor aesthetic effects. Modified coronally advanced flaps, flaps prepared by the technique of half-thickness, full-thickness and half-thickness, and modified coronally advanced envelope flap technology are designed with the most serious retraction teeth as the center in the case of multiple gingival retractions, both of which can improve the effect of root covering. Tunnel technology and modified tunnel technology, without severing the gingival papilla and tunneling the gingival flap to accommodate the graft, can effectively reduce tissue damage and promote wound healing. This paper reviews the literature and summarizes the outcome of the modified surgery techniques in the treatment of gingival recession. These treatment options for gingival recession are proposed with the aim of improving clinical work, and some suggestions for the treatment of gingival recession to achieve a stable root coverage effect are put forward. In the future, the development direction of mucogingival surgery is to reduce trauma and have a stable curative effect.

Trigger Finger or De Quervain Tenosynovitis after Surgical Treatment for Carpal Tunnel Syndrome / Dedo em gatilho ou tenossinovite de De Quervain após tratamento cirúrgico da síndrome do túnel do carpo

Abstract Objective To evaluate the open surgical treatment for carpal tunnel syndrome as a risk factor for the development of stenosing tenosynovitis that results in trigger finger and De Quervain disease. Materials and Methods A retrospective study analyzing the medical records of patients submitted to open surgical release of carpal tunnel syndrome between 2010 and 2021 in a secondary- and tertiary-level hospital. The following data were collected: pathological history, duration of the follow-up after the surgical treatment for carpal tunnel syndrome, development of trigger finger or De Quervain tenosynovitis, affected fingers, and the interval between the end of surgery and symptom onset. Results We evaluated 802 patients of both genders and with a mean age of 50.1 (±12.6) years. The mean follow-up was of 13 (±16.4) months. The mean time until the development of trigger finger was of 61.4 months, and of 73.7 months for De Quervain disease. The incidence of development of De Quervain disease was of 4.12%, and for trigger finger it was of 10.2%. The most affected digits were the thumb (47.6%), the middle (24.4%), and the ring finger (8.54%). Age was the only factor that showed an association with the risk of developing trigger finger, with an increase of 2% for each increase in age of 1 year. Conclusion The incidence rates for the development of De Quervain disease (4.12%) and trigger finger (10.2%) after the surgical treatment for carpal tunnel syndrome were like those described in the literature. Only age was a factor that influenced the development of trigger finger.

A modified tunnel technique to treat multiple gingival recessions: Case Series

Abstract This case series reports a modified tunnel technique with connective tissue graft for the root coverage of multiple Miller Class I, II, and III gingival recessions. The modified approach presents an innovative suture technique to improve the stability and position of the graft. Ten patients with multiple gingival recessions (n=85 teeth) received surgical root coverage treatment. The gingival recession height and width were measured and presented as median, minimum, and maximum values. The percentage of the root coverage after at least 12 months expressed the treatment effectiveness. The Shapiro-Wilk test evaluated the normality; pared Wilcoxon test determined the exact P-value for the differences in the height of the gingival recession before and after surgical treatment (α = 0.05). An average of 97.9% (± 5.6%, p < 0.0001) root coverage after treatment occurred, and 73 out of 85 recessions presented complete root coverage after 12 months. Treatment of Miller class I and II gingival recessions resulted in root coverage higher than 99 and class III higher than 95% (p < 0.0001). The presented case series report the efficacy of a modified surgical technique promoting more than 95% of root coverage after 12 months in multiple Miller Class I, II, and III gingival recessions. Well-designed blind randomized controlled trials are needed to validate the proposed technique.

Resumo Esta série de casos relata uma técnica de túnel modificada com enxerto de tecido conjuntivo para o recobrimento radicular de múltiplas recessões gengivais Classe I, II e III de Miller. A abordagem modificada apresenta uma técnica de sutura inovadora para melhorar a estabilidade e a posição do enxerto. Dez pacientes com múltiplas recessões gengivais (n=85 dentes) receberam tratamento cirúrgico de recobrimento radicular. A altura e a largura da recessão gengival foram mensuradas e apresentadas como valores medianos, mínimos e máximos. A eficácia do tratamento foi expressa como uma porcentagem da cobertura radicular após pelo menos 12 meses. O teste de Shapiro-Wilk avaliou a normalidade; o teste de Wilcoxon pared determinou o valor P exato para as diferenças entre a altura da recessão gengival antes e após o tratamento cirúrgico (α = 0,05). Uma média de 97,9% (± 5,6%, p < 0,0001) de cobertura radicular após o tratamento ocorreu, e 73 das 85 recessões apresentaram cobertura radicular completa após 12 meses. O tratamento das recessões gengivais classe I e II de Miller resultou em recobrimento radicular superior a 99 e classe III superior a 95% (p < 0,0001). A série de casos apresentada relata a eficácia de uma técnica cirúrgica modificada promovendo mais de 95% de cobertura radicular após 12 meses em múltiplas recessões gengivais Classe I, II e III de Miller. Ensaios controlados randomizados cegos bem desenhados são necessários para validar a técnica proposta.

Endoscopic Release of the Ulnar Nerve at the Elbow: Technique Description and Case Series / Liberação endoscópica do nervo ulnar no cotovelo: Descrição da técnica e série de casos

Abstract Objective The endoscopic release of the ulnar nerve reproduces a simple (in situ) procedure with smaller incisions, less soft tissue damage, and higher preservation of nerve vascularization. Endoscopy allows the clear visualization of the entire path of the nerve and surrounding noble structures. Moreover, it reveals any signs of compression and allows a safe release of 10cm distally or proximally to the medial epicondyle. Methods A retrospective survey revealed that 15 subjects (1 with a bilateral injury) underwent an ulnar nerve compression release at the elbow using the endoscopic technique with Agee (Micro-Aire Sugical Instruments, Charlottesville, VA, EUA) equipment from January 2016 to January 2020. Results Symptoms of ulnar nerve compression improved in all patients; on average, they resumed their work activities in 26.5 days. There was no recurrence or need for another procedure. In addition, there were no severe procedure-related complications, such as infection and nerve or vascular injury. One patient had transient paresthesia of the sensory branches to the forearm, with complete functional recovery in 8 weeks. Conclusion Our study shows that the endoscopic release of the ulnar nerve at the elbow with the Agee equipment is a safe, reliable technique with good outcomes.

Resumo Objetivo A liberação endoscópica do nervo ulnar permite reproduzir uma liberação simples (in situ), mas através de incisões menores e com menor lesão de partes moles e uma maior preservação da vascularização do nervo. A visualização clara através da endoscopia permite observar todo o trajeto do nervo e das estruturas nobres circundantes, mostrando os sinais de compressão, possibilitando realizar a liberação de forma segura em um trajeto de 10 cm nos sentidos distal e proximal ao epicôndilo medial. Método Foram encontrados, de forma retrospectiva, no período entre janeiro de 2016 e janeiro de 2020, 15 pacientes (sendo 1 com lesão bilateral) submetidos a liberação da compressão do nervo ulnar no cotovelo pela técnica endoscópica com equipamento de Agee (Micro-Aire Sugical Instruments, Charlottesville, VA, EUA). Resultados Todos os pacientes tiveram melhora dos sintomas de compressão do nervo ulnar e o período de retorno ao trabalho foi de em média 26,5 dias. Não houve recidivas e não houve a necessidade de outro procedimento. Também não houve complicações graves decorrentes do procedimento, como infecção, lesão nervosa ou vascular. Em um paciente, houve parestesia transitória dos ramos sensitivos para o antebraço, com retorno completo da função em 8 semanas. Conclusão Os resultados mostram que a liberação endoscópica do nervo ulnar no cotovelo comoequipamentodeAgeeéuma técnica segura, confiável e com bons resultados.

Ultrasound-Guided WALANT Technique in Carpal Tunnel Decompression Surgery* / Técnica WALANT guiada por ultrassom na cirurgia de descompressão do túnel do carpo

Abstract Carpal tunnel syndrome (CTS) is the most common compressive neuropathy in the human body. Its symptoms result from compression of the median nerve in the carpus. The treatment can be conservative, with medications and/or infiltrations that alleviate the symptoms, or surgical, which is more effective, with decompression of the median nerve by surgical section of the flexor retinaculum of the carpus. The anesthetic technique varies according to the anesthesia method: sedation, venous locoregional anesthesia and, more recently, wide-awake local anesthesia no tourniquet (WALANT), which can be performed by the surgeons themselves. The WALANT technique uses local anesthesia with a vasoconstrictor, and does not require the use of a tourniquet on the upper limb nor sedation. The median nerve block in ultrasound-guided WALANT provides better accuracy to the technique, with greater patient safety; in the present article, its use in the performance of carpal tunnel decompression is described, and the literature is reviewed.

Resumo A síndrome do túnel do carpo (STC) é a neuropatía compressiva mais comum do corpo humano. Seus sintomas decorrem da compressão do nervo mediano no carpo. O tratamento pode ser incruento, com medicações e/ou infiltrações que amenizam os sintomas, ou cruento, mais eficaz, com a descompressão do nervo mediano pela seção cirúrgicadoretináculodos flexores do carpo. A técnica anestésica varia de acordo com o serviço de anestesia: sedação, anestesia locorregional venosa e, mais recentemente, a anestesia local com o paciente acordado e sem torniquete (wide-awake local anesthesia no tourniquet, WALANT), que pode ser realizada pelo próprio cirurgião. Por utilizar anestesia local com vasoconstritor, essa técnica dispensa o uso de torniquete no membro superior e a necessidade de sedação. O bloqueio do nervo mediano na WALANT guiada por ultrassonografiaconfere melhor precisão àtécnica,e mais segurança ao paciente, e, neste artigo seu uso na realização da descompressão do túnel do carpo é descrito, e a literatura, revisada.

Diagnostic Contradictions in Carpal Tunnel Syndrome / Contradições diagnósticas na síndrome do túnel do carpo

Abstract Objective Given the divergence of opinions on the need for complementary tests such as ultrasonography (US) and electroneuromyography (ENMG) for the diagnosis of carpal tunnel syndrome (CTS), we aimed to elucidate which of them presents greater accuracy for the confirmation of the presence or not of this condition. Methods A total of 175 patients from a hand surgery outpatient clinic were clinically evaluated, and the results of clinical trials (Tinel, Phalen and Durkan), US (normal or altered), and ENMG (normal, mild, moderate and severe) were noted, crossed, and submitted to a statistical analysis to verify the agreement between them. Results with the sample had a mean age of 53 years, with a prevalence of female patients (159 cases). Of the patients with positive clinical test, 43.7% had normal US and 41.7% had no alterations on the ENMG. Negative results were found on the Tinel in 46.9%, on the Phalen in 47.4%, and on the Durkan in 39.7%. In the crossing between the results of the ENMG and those of the other diagnostic methods, there was little statistical agreement between them. Conclusion There was no agreement between the results of the clinical examinations, the US and the ENMG in the diagnosis of CTS, and there is no clinical or complementary examination for CTS that accurately determines the therapeutic approach. Level of Evidence IV, Case Series.

Resumo Objetivo Diante da divergência sobre a necessidade de exames complementares, como ultrassonografia (US) e eletroneuromiografia (ENMG) para o diagnóstico da síndrome do túnel do carpo (STC), objetivamos elucidar qual deles apresenta maior precisão na confirmação da presença ou não desta afecção. Métodos Um total de 175 pacientes de um ambulatório de cirurgia da mão foram avaliados clinicamente, e os resultados dos testes clínicos (Tinel, Phalen e Durkan), da US (normal ou alterada) e da ENMG (normal, leve, moderada e grave) foram anotados, cruzados, e submetidos a análise estatística para verificar a concordância entre eles. Resultados A idade média da amostra era de 53 anos, sendo prevalente o sexo feminino (159 casos). Dos pacientes com teste clínico positivo, 43,7% apresentavam US normal, e 41,7%, ENMG sem alterações. Foram encontrados resultados negativos no Tinel em 46,9% no Phalen em 47,4%, e no Durkan em 39,7%. No cruzamento entre a ENMG e os demais métodos diagnósticos, houve pouca concordância estatística. Conclusão Não houve concordância entre os resultados dos exames clínicos, da US e da ENMG no diagnóstico da STC, e não há exame clínico ou complementar para STC que determine a conduta terapêutica com precisão. Nível de Evidência IV, Série de Casos.

Acute Carpal Tunnel Syndrome due to Persistent Median Artery thrombosis: Case report / Síndrome do túnel do carpo aguda por trombose da artéria mediana: Relato de caso

Abstract Carpal tunnel syndrome is the most common compressive neuropathy of the upper limb, affecting ~ 4% of the general population. The clinical picture is characterized by pain and, mainly, paresthesia in the median nerve territory, of insidious onset and, in the most severe cases, loss of strength and atrophy of the thenar musculature is observed. It is an extremely common pathology in the daily practice of hand surgery, and in most cases, it can be treated with conservative methods. We present here an atypical case of carpal tunnel syndrome, of acute onset, triggered by persistent median artery (PMA) thrombosis, condition associated with distal embolization and hypoper-fusion of the limb.

Resumo A síndrome do túnel do carpo é a neuropatia compressiva mais comum do membro superior, afetando ~ 4% da população geral. O quadro clínico caracteriza-se por dor e, principalmente, parestesia no território do nervo mediano, de início insidioso e, nos casos mais graves, observa-se perda de força e atrofia da musculatura tenar. Trata-se de patologia extremamente comum na prática diária de cirurgia da mão, e na maior parte dos casos pode ser tratada com métodos conservadores. Apresentamos aqui um caso atípico de síndrome do túnel do carpo, de surgimento agudo, desencadeado pela trombose da artéria mediana persistente, quadro associado com embolização distal e hipoperfusão do membro.

An Intraindividual Comparison of Open versus Paine Retinaculotome Release for Bilateral Carpal Tunnel Syndrome / Comparação intraindividual dos resultados da liberação aberta ou com retinaculótomo de Paine na síndrome do túnel do carpo bilateral

Abstract The main purpose of this research was to do an intraindividual comparison of outcomes between the open ulnar incision (OUI) and the Paine retinaculotome with palmar incision (PRWPI) techniques in patients with bilateral carpal tunnel syndrome (CTS). The patients underwent OUI surgery on one hand and PRWPI surgery on the contralateral hand. The patients were evaluated with the Boston carpal tunnel questionnaire, visual analogue scale for pain, palmar grip strength, and fingertip, key, and tripod pinch strengths. Both hands were examined in the preoperative and postoperative periods after 2 weeks, 1 month, and 3 and 6 months. Eighteen patients (36 hands) were evaluated. The symptoms severity scale (SSS) scores were higher, in the preoperative period, in the hands that underwent surgery with PRWPI (p-value =0,023), but lower in the 3rd month postoperative (p-value = 0.030). The functional status scale (FSS) scores were lower in the periods of 2 weeks, 3 months, and 6 months (p-value = 0,016) on the hands that underwent surgery with PRWPI. In a different two-group module study, the PRWPI group presents the SSS scores average on the 2nd week and 1st month, and the FSS scores average on the 2nd week, less 0.8 and 1.2 points respectively comported to open group. The hands that underwent surgery with PRWPI presented significantly lower SSS scores at 3 months postoperative, and lower FSS scores at 2 weeks, and 3 and 6 months postoperative, compared to open surgery group.

Resumo O principal objetivo desta pesquisa foi fazer uma comparação intraindividual dos resultados entre as técnicas de incisão ulnar aberta e retinaculótomo de Paine com incisão palmar em pacientes com síndrome do túnel do carpo (STC) bilateral. Os pacientes foram submetidos à cirurgia aberta em uma mão e cirurgia com retinaculótomo de Paine na mão contralateral. Os pacientes foram avaliados com o Boston carpal tunnel questionnaire, escala visual analógica para dor e força de preensão palmar, pinça lateral, pinça polpa-polpa e trípode. As duas mãos foram examinadas antes da cirurgia e 2 semanas, 1 mês, 3 e 6 meses após a cirurgia. Dezoito pacientes (36 mãos) foram avaliados. As pontuações da escala de gravidade dos sintomas (EGS) foram maiores no pré-operatório nas mãos submetidas à cirurgia com retinaculótomo de Paine (p = 0,023), mas menores no 3° mês após o procedimento (p = 0,030). As pontuações da escala de estado funcional (EEF) foram menores às 2 semanas, 3 meses e 6 meses (p = 0,016) nas mãos submetidas à cirurgia com retinaculótomo de Paine. Em um estudo de módulo de diferença de dois grupos, o grupo submetido à cirurgia com retinaculótomo de Paine apresentou pontuações médias de EGS na 2ª semana e 1° mês e de EEF na segunda semana inferiores a 0,8 e 1,2 pontos, respectivamente, em comparação ao grupo submetido ao procedimento aberto. As mãos submetidas à cirurgia com retinaculótomo de Paine apresentaram escores significativamente menores de EGS em 3 meses e de EEF em 2 semanas, e aos 3 e 6 meses após a cirurgia em comparação a técnica aberta.

Clinical and electrophysiological efficacy of extracorporeal shock-wave therapy in carpal tunnel syndrome: a placebo-controlled, double-blind clinical trial

SUMMARY OBJECTIVE: The aim of this study was to evaluate the efficacy of radial extracorporeal shock wave therapy on pain, functionality, and electrophysiological measurements in carpal tunnel syndrome. METHODS: Between June 2021 and January 2022, a total of 66 wrists in 45 participants with mild-to-moderate carpal tunnel syndrome were included in this double-blind, prospective, randomized, placebo-controlled study. Patients were randomized into two groups, namely, the radial extracorporeal shock wave therapy (group 1, n=33) and the sham radial extracorporeal shock wave therapy (group 2, n=33). Night splints and tendon nerve gliding exercises were given to all participants. The participants were evaluated at baseline and the first month after treatment. Participants were evaluated using a visual analog scale, the Boston Carpal Tunnel Questionnaire, Leeds Neuropathic Symptom and Symptom Assessment, and electrophysiological examinations. RESULTS: A total of 37 participants (a total of 55 wrists, radial extracorporeal shock wave therapy n=27, and sham radial extracorporeal shock wave therapy n=28) completed the study. After the intervention, there was a significant decrease in visual analog scale values (p<0.001) and a significant increase in Boston Carpal Tunnel Questionnaire scores (p<0.001) and Leeds Neuropathic Symptom and Symptom Assessment scores (p<0.001). In electrophysiological measurements, there was a significant decrease in median nerve sensory (p=0.002) and motor (p=0.003) distal latency, and a significant increase in median nerve sensory conduction velocity (p=0.026) was found in the radial extracorporeal shock wave therapy group. CONCLUSION: This study shows that radial extracorporeal shock wave therapy has positive effects on pain, functionality, and electrophysiological measurements for mild-to-moderate carpal tunnel syndrome 1 month after application.

Quality analysis of prior systematic reviews of carpal tunnel syndrome: an overview of the literature

ABSTRACT BACKGROUND: Carpal tunnel syndrome (CTS) is a common condition greatly affects patients' quality of life and ability to work. Systematic reviews provide useful information for treatment and health decisions. OBJECTIVE: This study aimed to assess the methodological quality of previously published systematic reviews on the treatment of CTS. DESIGN AND SETTING: Overview of systematic reviews conducted at the Brazilian public higher education institution, São Paulo, Brazil METHODS: We searched the MEDLINE and Cochrane Library database for systematic reviews investigating the treatment of CTS in adults. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and measurement tool to assess systematic reviews (AMSTAR) were applied by two independent examiners. RESULTS: Fifty-five studies were included. Considering the stratification within the AMSTAR measurement tool, we found that more than 76% of the analyzed studies were "low" or "very low". PRISMA scores were higher when meta-analysis was present (15.61 versus 10.40; P = 0.008), while AMSTAR scores were higher when studies performed meta-analysis (8.43 versus 5.59; P = 0.009) or when they included randomized controlled trials (7.95 versus 6.06; P = 0.043). The intra-observer correlation demonstrated perfect agreement (> 0.8), a Spearman's correlation coefficient of 0.829, and an ICC of0.857. The inter-observer correlation indicated that AMSTAR was more reliable than PRISMA. CONCLUSION: Overall, systematic reviews of the treatment of CTS are of poor quality. Reviews with better-quality conducted meta-analysis and included randomized controlled trials. AMSTAR is a better tool than PRISMA because it has a better performance and should be recommended in future studies.

Diagnostic criteria and outcome measures in randomized clinical trials on carpal tunnel syndrome: a systematic review

ABSTRACT BACKGROUND: The diagnostic criteria for carpal tunnel syndrome (CTS) lack uniformity. Moreover, because CTS is a syndrome, there is no consensus as to which signs, symptoms, clinical and complementary tests are more reproducible and accurate for use in clinical research. This heterogeneity is reflected in clinical practice. Thus, establishing effective and comparable care protocols is difficult. OBJECTIVE: To identify the diagnostic criteria and outcome measures used in randomized clinical trials (RCTs) on CTS. DESING AND SETTING: Systematic review of randomized clinical trials carried out at the Federal University of São Paulo, São Paulo, Brazil. METHODS: We searched the Cochrane Library, PubMed, and Embase databases for RCTs with surgical intervention for CTS published between 2006 and 2019. Two investigators independently extracted relevant data on diagnosis and outcomes used in these studies. RESULTS: We identified 582 studies and 35 were systematically reviewed. The symptoms, paresthesia in the median nerve territory, nocturnal paresthesia, and special tests were the most widely used clinical diagnostic criteria. The most frequently assessed outcomes were symptoms of paresthesia in the median nerve territory and nocturnal paresthesia. CONCLUSION: The diagnostic criteria and outcome measures used in RCTs about CTS are heterogeneous, rendering comparison of studies difficult. Most studies use unstructured clinical criteria associated with ENMG for diagnosis. The Boston Questionnaire is the most frequently used main instrument to measure outcomes.

Results of surgical treatment of carpal tunnel syndrome using two variations of open technique / Resultados do tratamento cirúrgico da síndrome do túnel do carpo por meio de duas variações da técnica aberta

ABSTRACT Transverse carpal ligament (TCL) opening is the treatment of choice for carpal tunnel syndrome. However, complications such as loss of grip strength and anterior displacement of the median nerve are described as common complications associated with this technique. Thus, techniques that reconstruct or extend TCL are described to reduce the incidence of these complications. Objective: To evaluate the effectiveness of TCL enlargement through Z-plasty and the reduction of complications by comparing it with the complete opening of the ligament. Materials and Methods: A prospective and randomized intervention study was conducted in 56 patients. They were divided into 2 groups: 1) complete opening of TCL 2) TCL enlargement via Z-plasty. We evaluated grip strength, sensitivity, and functional evaluation using the QuickDASH questionnaire. Results: There was no statistically significant difference in the improvement of scores with QuickDASH between the two techniques. The sensitivity test was better in patients subjected to TCL enlargement, whereas grip strength increased in the group subjected to complete TCL opening. Conclusion: According to the results of this study, the complete opening of the TCL showed no reduction in grip strength, although it showed inferior recovery to postoperative sensitivity. Both techniques were equivalent in functional improvement. Thus, Z-plasty showed no identifiable benefits for TCL enlargement. Level of Evidence III, Randomized Clinical Trial.

RESUMO A abertura completa do ligamento transverso do carpo (LTC) é o tratamento de escolha para a síndrome do túnel do carpo. No entanto, complicações como perda de força de preensão e deslocamento anterior do nervo mediano são complicações comuns associadas a essa técnica. Assim, descrevem-se técnicas que reconstroem ou alargam o LTC visando reduzir a incidência dessas complicações. Objetivo: Avaliar a efetividade do alargamento do LTC através de Z-plastia e a diminuição das complicações, comparando a técnica com a abertura completa do ligamento. Métodos: Realizou-se um estudo de intervenção, prospectivo e randomizado com 56 pacientes. Estes foram divididos em dois grupos: 1) abertura completa do LTC e 2) alargamento do LTC através de Z-plastia. Avaliamos força de preensão e sensibilidade e realizamos avalição funcional por meio do questionário Quick Disabilities of Arm, Shoulder and Hand (QuickDASH). Resultados: Não houve diferença estatisticamente significante na melhora dos escores entre as duas técnicas. O teste de sensibilidade teve melhores resultados nos pacientes submetidos ao alargamento do LTC, enquanto a força de preensão teve maior acréscimo no grupo submetido à abertura completa do LTC. Conclusão: A abertura completa do LTC não levou à redução da força de preensão, apesar de ter se mostrado inferior na recuperação da sensibilidade no pós-operatório. As duas técnicas foram equivalentes na melhora funcional. Dessa forma, não encontramos benefícios identificáveis na realização da Z-plastia para alargamento do LTC. Nível de Evidência III, Ensaio Clínico Randomizado.

Facial contouring surgery combined with the clinical application of minimally invasive tunnel separation and lifting technique / 中华医学美学美容杂志

Objective:To explore a simple and effective clinical method for improving facial sagging while performing maxillofacial contouring surgery.Methods:From October 2020 to October 2021, 50 patients with mandibular angle and malar surgery in the Plastic Surgery Department of Sichuan Friendship Hospital were selected, aged 30-43 years, with the average age of 37 years, including 44 females and 6 males. Maxillofacial contouring surgery was performed under transnasal intubation general anesthesia, the interorgual jaw groove incision was performed with a swing saw for bilateral long arc osteotomy, and the maxillary gingival groove incision and sideburn skin incision were performed for zygomatic osteotomy reduction and zygomatic arch incision. A small incision about 3 mm long was taken 1 cm from the edge of the temporal hair; a special conical cannula stripper was used to perform subcutaneous tunnel peeling to the zygomatic fat pad and masseter muscle ligament, anterior appendage ligament, then a two-way barb line was placed through the casing to lift vertically upwards, pierce above the posterior papillae of the ear, and the excess thread was cut off.Results:Following-up for 3-12 months, all recipients recovered well after surgery, the skin of the middle and lower parts of the postoperative body was lifted to varying degrees, the cheek fat pad was lifted, the jaw contour line was clearer, and the nasolabial fold was significantly improved as compared with that before the operation.Conclusions:At the same time as facial contouring surgery, the use of minimally invasive tunnel separation and lifting technique can effectively improve the skin sagging in the middle and lower parts, and it is simple and effective, and the clinical application effect is good.

Arthroscopic reduction and double-tunnel button fixation of fractures of the tibial intercondylar eminence in children / 中华创伤骨科杂志

Objective:To investigate the efficacy of arthroscopic reduction and double-tunnel button fixation in the treatment of fractures of the tibial intercondylar eminence in children.Methods:From January 2019 to June 2022, 8 children with fracture of the tibial intercondylar eminence were treated at Orthopedics Department, Shenzhen Children's Hospital with arthroscopic reduction and double-tunnel button fixation. They were 6 boys and 2 girls, with an age of (8.4±1.9) years. Injured sites: 4 left knees and 4 right knees. Their operation time, intraoperative blood loss, knee flexion and extension, and complications were recorded. Their Lysholm scores were compared between preoperation and the last follow-up.Results:The operation time was (161.9±57.9)min. All patients were followed up for (12.1±5.7) months. The intraoperative blood loss was 3.5 (1.0,4.3)mL. Their knee flexion was 145.0°±5.0° and extension 0.9°±1.2° after operation. All their incisions healed at one stage, with no postoperative infection or other complications. Their preoperative Lysholm score [(20.3±15.8) points (from 2 to 54 points)] increased significantly to (99.3±1.0) points (from 98 to 100 points) after operation ( P<0.05). Conclusions:Arthroscopic reduction and double-tunnel button fixation is effective for fractures of the tibial intercondylar eminence in children, leading to limited complications, limited bleeding and a low infection rate.

Comparison of the efficacy and long-term stability of tunnel technique and coronally advanced flap in the treatment of gingival recession: a Meta-analysis / 华西口腔医学杂志

OBJECTIVES@#This study aimed to evaluate the efficacy and long-term stability of tunnel technique (TUN) and coronally advanced flap (CAF) combined with connective tissue graft (CTG) in treating gingival recession.@*METHODS@#Databases including PubMed, Web of Science, Embase, and CNKI were electronically searched to collect randomized controlled trial (RCT) of CAF+CTG compared to TUN+CTG in the treatment of Miller class Ⅰ or Ⅱ gingival recession on September 1, 2022.@*RESULTS@#There were 8 RCTs with 305 patients (454 recession sites) participating. The results of the Meta-analysis revealed that, in terms of mean root coverage (MRC) of main indicators, no significant difference was found between the CAF group and the TUN group in both short- and long-term results, which were [MD: 1.45%, 95%CI (-2.93%, 5.82%), P=0.52] and [MD: -0.70%, 95%CI (-6.41%, 5.00%), P=0.81]. However, the CAF group outperformed the TUN group in the long term [MD: 5.69%, 95%CI (0.87%, 10.50%), P=0.02], and the results of complete root coverage (CRC) analysis were similar to those of MRC. In the short term, the TUN group grew keratinized gingiva significantly faster than the CAF group [MD: -0.38 mm, 95%CI (-0.67 mm, -0.10 mm), P=0.008]. Long-term findings revealed no significant difference between the two groups [MD: -0.26 mm, 95%CI (-0.94 mm, 0.43 mm), P=0.46]. The TUN group's secondary index root coverage esthetic score (RES) was statistically significantly higher than the CAF group's [MD: 0.62, 95%CI (0.28, 0.96), P=0.000 3]. Given that there were few results included in the literature and the heterogeneity was too great, no significant difference was observed in the postoperative VAS pain index score [MD: 0.53, 95%CI (-1.96, 3.03), P=0.68].@*CONCLUSIONS@#This study discovered that both CAF+CTG and TUN+CTG can achieve good root coverage in treating gingival recession, with CAF outperforming TUN and both groups achie-ving good long-term stability. After the operation, the TUN group had a higher RES than the CAF group. Given the limitations of this study, more high-quality studies are needed in the future to demonstrate the efficacy of TUN in gingival retraction surgery.

Accuracy of Femoral Tunnel Placement between Anteromedial and Anterolateral Visualisation Portals in Anterior Cruciate Ligament Reconstruction - Outcomes of a CT based Cross-Sectional Study

@#Introduction: Anatomical femoral tunnel placement is critical for anterior cruciate ligament reconstruction (ACLR). Tunnel placement may vary with different surgical techniques. The aim of this study was to compare the accuracy of femoral tunnel placement between the Anteromedial (AM) and Anterolateral (AL) visualisation portals on post-operative CT scans among a cohort of ACLR patients. Materials and methods: This cross-sectional study was conducted from January 2018 to March 2020 after obtaining ethics clearance. Patients who went for arthroscopic ACLR in our institute were divided into an AM (group 1) and an AL (group 2) based on the visualisation portal for creating the femoral tunnel and a 3D CT scan was done. The femoral tunnel position was calculated in deep to shallow and high to low direction using the Bernard Hertel grid. Femoral tunnel angle was measured in the 2D coronal image. Statistical analysis was done with the data collected. Results: Fifty patients with an average age of 26.36 (18-55) years ±7.216 SD were enrolled in the study. In this study, the AM technique was significantly more accurate (p<0.01) than the AL technique in terms of femoral tunnel angle. Furthermore, the deep to the shallow position was significantly (p= 0.018) closer to normative values, as determined by the chi-square test. The chances of error in tunnel angle in femoral condyle are 2.6 times greater in the AL technique (minimal clinical difference). Conclusion: To conclude, in ACLR the anteromedial visualisation portal can facilitate accurate femoral tunnel placement compared to the anterolateral visualisation portal.
