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.

A Importância dos Métodos de Determinação das Idades Esquelética e Dentária na Ortodontia e Odontopediatria ­ uma Revisão de Literatura / The Importance of Methods for Determination of Squeletal and Dental Age in Orthodontics and Pediatric Dentistry ­ a Literature Review

O estágio de desenvolvimento humano é intimamente relacionado à sua maturidade óssea ou dentária, sendo essencial para a escolha do tratamento de alterações dentofaciais em crianças e adolescentes por ortodontistas e odontopediatras. Existem diversos indicadores biológicos para determinar a maturação do indivíduo, como a idade cronológica e as alterações hormonais, porém esses indicadores podem sofrer interferências. Visando uma determinação de desenvolvimento e dos picos de crescimento mais precisa, para um melhor diagnóstico e plano de tratamento, foram desenvolvidos diversos métodos para determinar a idade esquelética e a idade dentária, sendo estes a avaliação da maturação carpal, da morfologia das vértebras cervicais, da fusão óssea da sincondrose esfeno-occipital e da sutura palatina mediana, bem como dos estágios da calcificação dentária. A avaliação das radiografias de mão e punho é o padrão ouro da predição da idade esquelética, e sua correlação com outros métodos já é evidente. Sendo assim, é possível utilizar a avaliação das vértebras cervicais e das idades dentárias de Nolla e Demirjian.

The stage of human development is closely related to bone or dental maturity, being essential for the choice of treatment for dentofacial changes in children and adolescents by orthodontists and pediatric dentists. There are several biological indicators to determine an individual's maturation, such as chronological age and hormonal changes, but these indicators can suffer interference. Aiming at a more accurate determination of development and growth peaks, for a better diagnosis and treatment plan, several methods have been developed to determine skeletal age and dental age, these being the assessment of carpal maturation, the morphology of the cervical vertebrae, bone fusion of the spheno-occipital synchondrosis and the median palatal suture, as well as the stages of dental calcification. The evaluation of hand and wrist radiographs is the gold standard for predicting skeletal age, and its correlation with other methods is already evident. Therefore, it is possible to use the assessment of cervical vertebrae and dental ages by Nolla and Demirjian.

Validity of the Maturation Stage Method in the Individual Assessment of Midpalatal Suture Ossification Before Maxillary Expansion: A Systematic Review / Validez del Método de la Etapa de Maduración en la Evaluación Individual de la Osificación de la Sutura Palatina Mediana Previo a la Expansión Maxilar: Una Revisión Sistemática

In 2013, midpalatal suture maturation stage assessment was proposed for the evaluation of patients before performing maxillary expansion. In this study, we aimed to analyze the association between the midpalatal suture maturation stages assessed by CBCT, according to the method described by Angelieri et al., and other objective methods used to assess skeletal maturation or bone fusion. A computerized database search was conducted using PubMed, Cochrane Library, SciELO, LILACS, Web of Science, and Scopus, without language restriction. Unpublished literature was searched on ClinicalTrials.gov, the National Research Register, and Pro-Quest Dissertation Abstracts and Thesis database. Authors were contacted when necessary, and reference lists of the included studies were screened. Search terms included midpalatal suture, maturation, correlation, diagnostic performance, classification, evaluation, assessment, and relationship. Quality assessment was performed using the Observational Cohort and Cross-Sectional Studies tool developed by the National Heart, Lung, and Blood Institute. Eleven studies met the inclusion criteria. Of all the studies included, 81.9% had fair qualit y and 18.1% good quality, respectively. Eight out of eleven studies assessed the correlation between the midpalatal suture maturation method and the skeletal maturity evaluated by CVM method (Spearman's correlation coefficient: 0.244-0.908). Two out of eleven studies evaluated the correlation between midpalatal suture maturation method and the skeletal maturity assessed by HWM method (Spearman's correlation coefficient: 0.904-0.905) Even though midpalatal suture maturation stage assessment needs an exhaustive training and calibration process, it is a valid method to evaluate skeletal maturation or bone fusion. From a clinical perspective, for patients at CS4, CS5 and CS6, an assessment of the midpalatal suture on CBCT is indicated. A similar assessment should be done in patients at SMI 7-9.

En 2013, se propuso un nuevo método para la evaluación del estadio de maduración de la sutura palatina mediana para la evaluación de los pacientes antes de realizar la expansión maxilar. En este estudio, nuestro objetivo fue analizar la asociación entre las etapas de maduración de la sutura palatina mediana evaluada en CBCT, según el método descrito por Angelieri et al., y otros métodos objetivos utilizados para evaluar la maduración esquelética o la fusión ósea. Se realizó una búsqueda en las bases de datos PubMed, Cochrane Library, SciELO, LILACS, Web of Science y Scopus, sin restricción de idioma. Se buscó literatura no publicada en ClinicalTrials.gov, el Registro Nacional de Investigación y la base de datos Pro-Quest Dissertation Abstracts and Thesis. Se estableció contacto con los autores cuando fue necesario y se revisaron las listas de referencias de los estudios incluidos. Los términos de búsqueda incluyeron sutura palatina mediana, maduración, correlación, rendimiento diagnóstico, clasificación, evaluación, valoración y relación. La evaluación de la calidad se realizó mediante la herramienta de Estudios transversales y de cohortes observacionales desarrollada por el Instituto Nacional del Corazón, los Pulmones y la Sangre. Once estudios cumplieron con los criterios de inclusión. Del total de estudios incluidos, el 81.9% tuvo calidad regular y el 18.1% calidad buena, respectivamente. Ocho de once estudios evaluaron la correlación entre el método de maduración de la sutura palatina mediana y la madurez esquelética evaluada por el método CVM (coeficiente de correlación de Spearman: 0.244-0.908). Dos de once estudios evaluaron la correlación entre el método de maduración de la sutura palatina mediana y la madurez esquelética evaluada por el método HWM (coeficiente de correlación de Spearman: 0.904-0.905). Aunque la evaluación del estado de maduración de la sutura palatina mediana necesita un proceso exhaustivo de entrenamiento y calibración, es un método válido para evaluar la maduración esquelética o la fusión ósea. Desde una perspectiva clínica, para pacientes en CS4, CS5 y CS6, está indicada una evaluación de la sutura palatina mediana en CBCT. Se debe realizar una evaluación similar en pacientes con SMI 7-9.

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.

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.

Design, sensitivity and validity of wrist patient self-evaluation instrument / 中华骨科杂志

Objective:To design a patient self-rating wrist scale suitable for Chinese patients, and evaluate its reliability and validity.Methods:The primary entry pool was established by referring to the existing foreign scales and the opinions of domestic experts. Opinions of 11 hand surgeons and 10 patients with wrist diseases were referred to select better items into the primary scale. During September 2015 to November 2016, 100 inpatients with wrist diseases in the hand surgery department of Beijing Jishuitan Hospital were selected by convenient sampling method, and the primary scale was conducted on them. Eight indices including item response rate, item differentiation, item-dimension attribution, variability, responsiveness, overall item attribution, internal consistency and factor loading were summarized. All the 8 indices were evaluated to establish the wrist patient self-evaluation instrument for Chinese. Test-retest reliability, Cronbach coefficient, expert score, KMO value, explanatory power, χ 2/df, root mean square error of approximation (RMSEA) and comparative fit index (CFI) were used to evaluate the reliability and validity of the scale. Results:A total of 40 subjective items in the primary entry pool were selected to form the primary scale, including 32 items (A1-D4), and 4 dimensions (physiology, safety, pain and emotion). There were 92 valid scale results in 100 cases. All cases' response rate were over 90%. In terms of item differentiation, only the high grouping score [3.20±0.577 points (range, 1-3 points)] and the low grouping score [2.68±0.627 points (range, 2-5 points)] of item B10 had no statistical significance ( t=5.11, P=0.340). There were 17 items: A1, A2, A5, A6, A7, A8, A9, A10, A11, A12, B4, B6, B7, C5, D1, D2, and D3 were considered to be deleted according to the result of item-dimension attribution.

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.

Comparison of second lumbrical interosseous median and ulnar motor conduction study in population of subjects with idiopathic carpal tunnel syndrome and non-CTS hands-a cross-sectional study

Background: Second lumbrical interosseous (2L-I) median-ulnar motor conduction study across wrist is pivotal in electrodiagnosis of carpal tunnel syndrome (CTS) in different grades of severity. 2L-I Median versus ulnar distal motor latency (DML) difference more than 0.5 milliseconds is used to diagnose median neuropathy at wrist. Other variables of study, namely, 2L DML, compound muscle action potential (CMAP) amplitude, CMAP duration, and conduction velocity (CV) remain less explored with few studies pressing for its role to substantiate CTS diagnosis. Aims and Objectives: Current cross-sectional study aimed to explore role of 2L-I DML, amplitude, duration, and CV in diagnosis of median neuropathy at wrist. Materials and Methods: Total 70, 37 clinically suspected CTS hands and 33 age, height, and weight matched non-CTS hands underwent 2L-I Median Ulnar motor conduction study. Results: Statistically significant difference (P < 0.05) in 2L median DML, CMAP amplitude, duration and CV between CTS and non-CTS hands along with 2L-I Median versus Ulnar DML difference. 2L DML and 2L-I DML difference variables showed better specificity and sensitivity: 83.78 and 93.91, respectively, in diagnosing CTS. Conclusion: We concluded that apart from 2L-I DML difference other variables such as DML, amplitude, duration, and CV may also play substantial role in evaluation of CTS and may be included as part of electrodiagnostic protocol.

Effect of Agnikarma with Tapta Guda in Carpal Tunnel Syndrome- A Case Study

Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy of upper extremity. It affects approximately 3% of the general adult population in the world. Women are three times more likely to have CTS than men. In conventional system, medications such as corticosteroids, Non-Steroidal anti-inflammatory drugs, etc., are used in management of carpal tunnel syndrome. Surgical decompression of carpal tunnel is the main stay of treatment for CTS. The structures involved in carpal tunnel is mainly the tendons, ligaments and nerves which can closely related with Snayu, thus Carpal tunnel syndrome can be correlated with Snayugata vata affecting Manibandhasandhi. Dahanopkarana used for Vatavyadi affecting Snayu, Sandhi, Asthi are Kshaudra, Guda, Sneha. Agnikarma with Snigdha dravyas have more penetrating capacity than Rooksha dravyas like Shalaka. So, Taptaguda is taken in the present study to assess the effect of Agnikarma in carpal tunnel syndrome. Here the patient was treated with Agnikarma using Taptaguda over the most painful and tender points. Assessments were done before treatment, after treatment, 7th day, 15th day and 30th day. The result showed Agnikarma with Taptha guda was effective in treating Carpal tunnel syndrome

Failure factors for carpal tunnel syndrome surgical treatment: When and how to perform a revision carpal tunnel decompression surgery / Fatores de insucesso do tratamento cirúrgico da síndrome do túnel do carpo: Quando e como revisar a cirurgia de descompressão do túnel do carpo

Abstract Despite being a procedure widely used all over the world with high rates of symptom remission, surgical treatment of carpal tunnel syndrome may present unsatisfactory outcomes. Such outcomes may be manifested clinically by non-remission of symptoms, remission of symptoms with recurrence a time after surgery or appearance of different symptoms after surgery. Different factors are related to this unsuccessful surgical treatment of carpal tunnel syndrome. Prevention can be achieved through a thorough preoperative clinical evaluation of the patient. As such, the surgeon will be able to make differential or concomitant diagnoses, as well as determine factors related to patient dissatisfaction. Perioperative factors include the correct identification of anatomical structures for complete median nerve decompression. Numerous procedures have been described for managing postoperative factors. Among them, the most common is adhesion around the median nerve, which has been treated with relative success using different vascularized flaps or autologous or homologous tissue coverage. The approach to cases with unsuccessful surgical treatment of carpal tunnel syndrome is discussed in more detail in the text.

Resumo Apesar de ser um procedimento amplamente utilizado em todo o mundo e com elevadas taxas de remissão dos sintomas, o tratamento cirúrgico da síndrome do túnel do carpo pode apresentar resultados não satisfatórios ao paciente. Esse resultado não satisfatório pode se manifestar clinicamente pela não remissão dos sintomas, remissão dos sintomas mas recorrência desses após um período de tempo da cirurgia ou aparecimento de diferentes sintomas após a cirurgia. Diferentes fatores estão relacionados a esse insucesso do tratamento cirúrgico da síndrome do túnel do carpo (ITCSTC). A prevenção pode ser conseguida por meio de minuciosa avaliação clínica do paciente no período pré-operatório. Dessa forma o cirurgião poderá fazer diagnósticos diferenciais ou diagnósticos concomitantes, assim como identificar fatores ligados a insatisfação do paciente. Os fatores per-operatórios incluem a correta identificação das estruturas anatômicas para completa descompressão do nervo mediano. Inúmeros procedimentos têm sido descritos para o tratamento dos fatores que ocorrem no período pós-operatório. Desses o mais comum, a formação de aderências em torno do nervo mediano, tem sido tratado com relativo sucesso utilizando diferentes retalhos vascularizados ou cobertura com o uso de tecido autólogo ou homólogo. Descreveremos a abordagem do ITCSTC com maiores detalhes no texto.

Síndrome de compresión del túnel del carpo y tercer dedo en gatillo secundarios a un fibrolipoma encapsulado de la muñeca: reporte de un caso / Carpal tunnel compression syndrome and third finger in trigger secondary to an encapsulated fibrolipoma of the wrist: a case report

Resumen: Introducción: la asociación del síndrome del túnel del carpo con tenosinovitis estenosante de la mano es muy rara, aún más, si es generada por un fibrolipoma a nivel del túnel del carpo. El estudio de imagen para detectar este tipo de lesiones en la mano incluye: desde una radiografía con proyección para el túnel del carpo, tomografía axial computarizada y resonancia magnética nuclear; pero éstos no se utilizan habitualmente para el estudio protocolizado del síndrome del túnel del carpo y mucho menos para los dedos en gatillo. Objetivo: el objetivo de este trabajo es reportar un caso en el cual se presenta la sintomatología característica de un síndrome de túnel del carpo, asociada a tercer dedo en gatillo, el cual se maneja con la liberación del nervio mediano por medio de un abordaje de mínima invasión, además de la polea A1. Caso clínico: la paciente persistió con ambas alteraciones y en la revisión secundaria se detectó bloqueo a nivel de la muñeca. Se intervino nuevamente a la paciente y se encontró una tumoración encapsulada, que midió 3.0 × 2.0 × 1.0 cm, con superficie externa lisa, blanquecina, de aspecto ovoide y consistencia blanda «ahulada¼. El estudio anatomopatológico la identificó como un fibrolipoma encapsulado que ocasionó la compresión nerviosa y el bloqueo del tendón flexor. Conclusión: la importancia de este reporte de caso radica en agregar los tumores al repertorio etiológico, que además pueden provocar una compresión del nervio mediano y en que sean aún menos frecuentes como causa de atrapamiento de los tendones flexores de la mano.

Abstract: Introduction: the association of carpal tunnel syndrome with stenosing tenosynovitis of the hand is very rare, even more, if it is generated by a fibrolipoma at the carpal tunnel. The imaging study useful to detect this type of hand injuries are X-ray screening for carpal tunnel, computed tomography and magnetic resonance imaging. But these are not commonly used for the study of protocolized carpal tunnel syndrome and much less trigger finger. Objective: the aim of this work is to report a case of a middle-aged female with carpal tunnel syndrome characteristic symptoms, associated with the third trigger finger; she was handled with the release of the median nerve by a minimally invasive approach, in addition to the A1 pulley release. Clinical case: the patient persists with both problems and at a secondary surgical review, we detected wrist locking sensation. The patient was reoperated finding an ovoid encapsulated tumor, measuring 3.0 × 2.0 × 1.0 cm, with smooth outer surface, whitish appearance, and soft rubbery consistency. The biopsy pathology outlines identified an encapsulated fibrolipoma, causing nerve compression and locking flexor tendon. Conclusion: the importance of this writing is in adding tumors to the etiological repertoire, which can cause compression of the median nerve and even less frequent as a cause of the flexor tendons of the hand snagging.

Prevalence of Anatomical Variations in Patients with Carpal Tunnel Syndrome Undergoing Classical Open Carpal Tunnel Release / Prevalência de variações anatômicas encontradas em pacientes com síndrome do túnel do carpo submetidos a liberação cirúrgica por via aberta clássica

Abstract Objective To evaluate the prevalence of anatomical variations encountered in patients with carpal tunnel syndrome who underwent carpal tunnel classical open release. Methods A total of 115 patients with a high probability of clinical diagnosis for carpal tunnel syndrome and indication for surgical treatment were included. These patients underwent electroneuromyography and ultrasound for diagnostic confirmation. They underwent surgical treatment by carpal tunnel classical open release, in which a complete inventory of the surgical wound was performed in the search and visualization of anatomical variations intra- and extra-carpal tunnel. Results The total prevalence of anatomical variations intra- and extra-carpal tunnel found in this study was 63.5% (95% confidence interval [CI]: 54.5-72.4). The prevalence of the carpal transverse muscle was 57.4% (95% CI: 47.8-66.6%), of the bifid median nerve associated with the persistent median artery was 1.7% (95% CI: 0.0-4.2%), and the median bifid nerve associated with the persistent median artery and the transverse carpal muscle was 1.7% (95% CI: 0.0-4.2%). Conclusion The most prevalent extra-carpal tunnel anatomical variation was carpal transverse muscle. The most prevalent intra-carpal tunnel anatomical variation was median bifid nerve associated with the persistent median artery. The surgical finding of an extra-carpal tunnel anatomical variation, such as the transverse carpal muscle, may indicate the presence of other associated carpal intra tunnel anatomical variations, such as the bifid median nerve, persistent median artery, and anatomical variations of the recurrent median nerve branch.

Resumo Objetivo Avaliar a prevalência de variações anatômicas encontradas em pacientes com síndrome do túnel do carpo submetidos a liberação cirúrgica por via aberta clássica. Métodos Foram incluídos um total de 115 pacientes com alta probabilidade de diagnóstico clínico de síndrome do túnel do carpo, com indicação para o tratamento cirúrgico. Estes pacientes realizaram eletroneuromiografia e ultrassonografia para confirmação diagnóstica. Foram submetidos ao tratamento cirúrgico por via aberta clássica, no qual foi realizado um inventário completo da ferida operatória na busca e visualização de variações anatômicas intra e extra túnel do carpo. Resultados A prevalência total das variações anatômicas intra e extra túnel do carpo encontradas neste estudo foi de 63,5% (intervalo de confiança [IC]95%: 54,5-72,4%). A prevalência do músculo transverso do carpo foi de 57,4% (IC95%: 47,8-66,6%), do nervo mediano bífido associado à artéria mediana persistente foi de 1,7% (IC95%: 0,0-4,2%) e do nervo mediano bífido associado à artéria mediana persistente e ao músculo transverso do carpo foi de 1,7% (IC95%: 0,0-4,2%). Conclusão A variação anatômica extra túnel do carpo mais prevalente foi o músculo transverso do carpo e a variação anatômica intra túnel do carpo mais prevalente foi o nervo mediano bífido associado à artéria mediana persistente. O achado cirúrgico de uma variação anatômica extra túnel do carpo, como o músculo transverso do carpo, pode nos indicar a presença de outras variações anatômicas intra túnel do carpo associadas, como nervo mediano bífido, artéria mediana persistente e variações anatômicas do ramo recorrente do nervo mediano.

Retrospective Study on the Radiographic Wrist Indices in a Nigerian Population.

Background: Evaluation of the degree of carpal collapse using radiographic wrist indices is important in the management of wrist diseases. These indices vary in different population groups, hence, the need for population-specific normal references. This study aimed at assessing the carpal height ratio using wrist radiographs of adult Nigerian patients.Materials and Methods: This retrospective study assessed wrist radiographs stored in the Radiology department of Delta State University Teaching Hospital, Oghara, Nigeria, following institutional approval. Apparently normal unpaired wrist radiographs of 135 adults (54 males and 81 females) were used to assess the 3rd metacarpal length, carpal height and capitate length which were used to calculate the carpal height ratio (CHR) and revised carpal height ratio (CHRr). Statistical Package for Social Sciences (SPSS) version 22 was used to analyze these quantitative variables. Independent t-test and Analysis of Variance (ANOVA) were used to probe for differences in gender groups and 10 years' age-groups respectively. Significance was considered at p<0.05. Results: The mean carpal height, capitate length and length of the 3rd metacarpal was 31.77 mm, 23.34 mm and 67.34 mm respectively. The mean CHR and CHRr was 0.47±0.04 and 1.36±0.07 correspondingly. All variables except CHRr were significantly larger in males than in females (p<0.05). All the parameters had no significant association with the age-groups (p>0.05). Conclusion: The CHR and CHRr in this study were lower than reports from other population groups. This study provides a reference database for our studied population to aid in accurate diagnosis and effective management of carpal collapse.
