OBJECTIVE@#To observe the clinical efficacy of lesion removal, bone grafting, fusion, and external fixation in the treatment of late-stage wrist tuberculosis.@*METHODS@#From October 2015 to May 2019, 25 patients with late-stage wrist tuberculosis were treated using lesion removal, bone grafting, fusion, and external fixation. Among these patients, there were 14 males and 11 females, aged from 40 to 74 years old, with an average age of (60.72±8.45) years old. The duration of the disease ranged from 5 to 24 months, with an average of (11.52±7.61) months. There were 11 cases of left wrist tuberculosis and 14 cases of right wrist tuberculosis, with 5 cases accompanied by sinus formation. Postoperative regular anti-tuberculosis treatment was continued. Visual analogue score (VAS), inflammatory indicators, Gartland-Werley wrist function score, and upper limb function score were observed before and after treatment.@*RESULTS@#All 25 patients were followed up for ranging from 12 to 36 months with an average of (19.7±6.3) months. At the latest follow-up, all wounds were healed satisfactorily, and there was no recurrence of tuberculosis or infection. VAS at one week before operation and three months after operation were (5.16±1.14) score and (1.68±0.80) score respectively. One week before operation and three months after operation, erythrocyte sedimentation rate (ESR) was (44.20±20.56) mm·h-1 and (14.44±1.14) mm·h-1, and C-reactive protein (CRP) was (12.37±7.95) mg·L-1 and (4.3±3.37) mg·L-1. The differences in all three data sets were statistically significant (P<0.01). According to Gartland-Werley wrist function scoring, the scores at one week before operation and one year after operation were (21.32±3.44) and (14.96±1.37) respectively, showed a statistically significant difference (P<0.01). According to the upper limb function score (disabilities of the arm, shoulder, and hand, DASH), the score was (70.52±7.95) at one week before operation and(28.84±2.30) at one year after operation. The difference was statistically significant (P<0.01). At the latest follow-up, no patient had a recurrence of tuberculosis.@*CONCLUSION@#The short-term clinical efficacy of treating wrist tuberculosis with lesion removal, bone grafting, fusion, and external fixation is satisfactory.

Radiological Evaluation of Volar Cortical Angle in the Anatolian Population / Evaluación Radiológica del Ángulo Cortical Volar en la Población Anatoliana

SUMMARY: Distal radius fractures are the most common fractures of the upper limb. The most commonly used method in the repair of these fractures is volar locking plates. Recently, the frequency of removal of volar locking plates after surgery has increased. There are many factors in its reduction. Anatomically, incompatibility of the distal end of the radius with volar locking plates is one of them. In previous studies, different volar cortical angle (VCA) values were found in other races. For this reason, this study aimed to determine the mean values by making VCA measurements of the Anatolian population. The study was designed retrospectively. In the study, measurements were made on computed tomography (CT) images of the distal end of the radius of 53 men and 28 women. Radial width, intermediate volar angle, and radial volar angle were measured in the images. On average, the radius width was 23.35±1.96 mm, and the intermediate volar angle was 26.02±.3.83°, radial volar angle was 24±3.07°. Radial width, intermediate volar angle, and radial volar angle differed significantly by gender (p<0.001). A significant correlation was found between radius width, intermediate volar angle, and radial volar angle values (p<0.001). It has been determined that the Anatolian population has a different VCA value than the European, Asian, and other populations. When using volar locking plates in distal radius fracture surgery, volar locking plates should be selected by considering the average values of the races.

Las fracturas del radio distal son las fracturas más comunes del miembro superior. El método más utilizado en la reparación de estas fracturas son las placas de bloqueo volar. Recientemente, ha aumentado la frecuencia de extracción de placas de bloqueo volar después de la cirugía. Existen muchos factores en su reducción y anatómicamente, la incompatibilidad de la extremidad distal del radio con las placas de bloqueo volar es una de ellas. En estudios anteriores, se encontraron diferentes valores del ángulo cortical volar (VCA) en otras grupos. Por esta razón, este estudio tuvo como objetivo determinar los valores medios, realizando mediciones de VCA de la población de Anatolia. El estudio fue diseñado de manera retrospectiva. En el estudio, se realizaron mediciones en imágenes de tomografía computarizada (TC) de la extremidad distal del radio de 53 hombres y 28 mujeres. En las imágenes se midieron el ancho radial, el ángulo volar intermedio y el ángulo volar radial. En promedio, el ancho del radio fue de 23,35 ± 1,96 mm, el ángulo volar intermedio fue de 26,02 ± 3,83° y el ángulo volar radial fue de 24 ± 3,07°. El ancho radial, el ángulo volar intermedio y el ángulo volar radial difirieron significativamente según el sexo (p<0,001). Se encontró una correlación significativa entre los valores del ancho del radio, el ángulo volar intermedio y el ángulo volar radial (p<0,001). Se ha determinado que la población de Anatolia tiene un valor de VCA diferente al de las poblaciones europeas, asiáticas y otras. Cuando se utilizan placas de bloqueo volar en cirugía de fractura de la extremidad distal del radio, las placas deben seleccionarse considerando los valores promedio de los individuos de diferentes grupos.

Analysis of Wrist Morphology Through Hamate and Lunate Bone Variations in Anatolian Population Using Plain Radiography / Análisis de la Morfología de la Articulación Radiocarpiana a Través de las Variaciones de los Huesos Hamato y Semilunar en la Población de Anatolia Mediante Radiografía Simple

SUMMARY: The present study aimed to evaluate wrist (lunate) anatomy in terms of the incidence of lunatum morphology on plain-radiographs among the Anatolian (Turkey) population, accompanied by demographic analysis. We obtained all the patients' data regarding demographical features, diagnosis, and posteroanterior (PA) X-ray imaging. Two radiograph-reviewers repeated the analysis twice, one month later, blinded to their findings before the previous review. The lunatum structure was determined as Type-1 (n:293) and Type-2 (n:207) for each radiograph. Most of the 500 wrists' radiographs [n:293 (58.6 %)] were type-I lunate. The mean age was 36.7±13.3 (range:18-90) years. Sex distribution was as follows: 185 (63.1 %) males to 108 (36.9 %) females. Type-2 lunate was seen in 207 participants (41.4 %). The mean age for type-2 was 41.6±15.2 (18-88) years. 142 (68.6 %) participants were male sex, while 65 (31.4 %) were females. The mean age of subjects with type-I showed a difference with type-II (p=0.007). There was no relationship in terms of sex (p=0.206) between the groups. In the Anatolian region, type-1 lunate was dominant compared to type-2. The incidence rate of lunate type in Anatolian population was similar to the Arab population.

El presente estudio tuvo como objetivo evaluar la anatomía de la articulación radiocarpiana en términos de la incidencia de la morfología del hueso semilunar en radiografías simples entre la población de Anatolia (Turquía), acompañado de un análisis demográfico. Obtuvimos todos los datos de los pacientes con respecto a las características demográficas, el diagnóstico y las imágenes de rayos X posteroanteriores (PA). Dos revisores de radiografías repitieron el análisis dos veces, un mes después, sin conocer sus hallazgos antes de la revisión anterior. La estructura del lunatum se determinó como Tipo-1 (n:293) y Tipo-2 (n:207) para cada radiografía. La mayoría de las 500 radiografías de muñecas [n:293 (58,6 %)] fueron semilunar tipo I. La edad media fue de 36,7±13,3 (rango: 18-90) años. La distribución por sexos fue la siguiente: 185 (63,1 %) hombres y 108 (36,9 %) mujeres. El semilunar tipo 2 se observó en 207 participantes (41,4 %). La edad media para el tipo 2 fue de 41,6±15,2 (18-88) años. 142 (68,6 %) participantes eran del sexo masculino, mientras que 65 (31,4 %) eran del sexo femenino. La edad media de los sujetos con tipo I mostró una diferencia con el tipo II (p = 0,007). No hubo relación en cuanto al sexo (p=0,206) entre los grupos. En la región de Anatolia, el semilunar tipo 1 era dominante en comparación con el tipo 2. La tasa de incidencia del tipo semilunar en la población de Anatolia fue similar a la de la población árabe.

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.

Total Wrist Arthrodesis: A Preoperative Test to Predict Functional Outcomes / Artrodese total do punho: Um teste pré-operatório para prever resultados funcionais

Abstract Objective The study aims to demonstrate an evaluation method to predict the functional success of total wrist arthrodesis (TWA) and assist its indication. Methods A prospective study including ten patients submitted to (TWA) posttraumatic arthritis. Exclusion criteria were patients who lost postoperative follow-up or incomplete information in the medical record. The objective functional assessment (handgrip strength, three-point pinch, lateral pinch and pulp-pulp pinch) and the subjective functional assessment (DASH, PRWE, EVA) were evaluated in 3 different periods: (1) Before surgery without articular anesthesia, (2) Before surgery under articular anesthesia and (3) 12 weeks after the surgical procedure. Results There was an increase in handgrip strength in all three pinches measurements after pain relief, both after joint anesthesia and after the consolidation of the arthrodesis (p < 0.05). In the comparisons between the subjective evaluations (DASH, PRWE and VAS), the patients had better scores in the postoperative evaluation after 12 weeks (p < 0.05). There was no statistical difference when comparing the mean strength values found after anesthesia and after 12 weeks of TWA. Conclusion the outcomes could propose an assessment protocol for patients with indication for TWA, in which patients with good response to intra-articular anesthetic infiltration would benefit from the effects of the surgical procedure.

Resumo Objetivo O estudo tem como objetivo demonstrar um método de avaliação para predizer o sucesso funcional da artrodese total do punho (ATP) e auxiliar na sua indicação. Métodos Um estudo prospectivo incluindo dez pacientes submetidos a ATP por artrite pós-traumática. Os critérios de exclusão foram pacientes que perderam o acompanhamento pós-operatório ou informações incompletas no prontuário. A avaliação funcional objetiva (força de preensão manual, pinça de três pontos, pinça lateral e pinça polpa-a-polpa) e a avaliação funcional subjetiva (DASH, PRWE, EVA) foram avaliadas em 3 momentos diferentes: (1) Antes da cirurgia sem anestesia articular, (2) Antes da cirurgia sob anestesia articular e (3) 12 semanas após o procedimento cirúrgico. Resultados Houve aumento da força de preensão palmar nas três medidas de pinça após o alívio da dor, tanto após a anestesia articular quanto após a consolidação da artrodese (p < 0,05). Nas comparações entre as avaliações subjetivas (DASH, PRWE e VAS), os pacientes tiveram melhores escores na avaliação pós-operatória após 12 semanas (p < 0,05). Não houve diferença estatística ao comparar os valores médios de força encontrados após a anestesia e após 12 semanas de ATP.

Use of Smartphones as a Risk Factor for the Development of Morbidities in the Wrist and Fingers / Uso de smartphones como fator de risco para o desenvolvimento de morbidades no punho e nos dedos*

Abstract Objective To investigate the long-term use of smartphones as a risk factor for the development of morbidities in the wrist and fingers. Methods The present is a descriptive, exploratory study with a quantitative approach based on injury prevalence among one hundred smartphone users of a private university in the state of Pernambuco, Northeastern Brazil. We applied a semi-structured questionnaire and the Boston Carpal Tunnel Questionnaire (BCTQ), as well as the Visual Analog Scale (VAS) and the Finkelstein, Phalen, reverse Phalen, and Tinel signal tests on the wrist. Results The average of the sample was of 22.73 years, with a prevalence of single, right-handed female participants. Most of them had been using smartphones for 5 to 10 years, and 85% reported discomfort in the wrist and fingers while using the device, with numbness as the most prevalent symptom. Most clinical tests were negative, and the Finklestein test showed greater positivity. The BCTQ is composed of a symptom severity scale (S scale) and a functional status scale (F scale): the overall score on the S scale was of 1.61, indicating mild to moderate symptoms, and the F scale revealed that the symptoms did not affect functionality. Conclusion There was a significant correlation between the length of use of smartphones and discomfort in the wrist and fingers; as such, smartphones are a risk factor for the development of morbidities.

Resumo Objetivo Investigar o uso de smartphones em longo prazo como fator de risco para o desenvolvimento de morbidades no nível do punho e dos dedos. Métodos Realizou-se um estudo descritivo, exploratório, de abordagem quantitativa, para a obtenção de medidas de prevalência com cem acadêmicos usuários de smartphones de uma faculdade privada localizada no sertão de Pernambuco. Foram aplicados um questionário semiestruturado e o Questionário de Síndrome doTúnel do Carpo de Boston (Boston Carpal Tunnel Questionnaire, BCTQ, na sigla em inglês), além da Escala Visual Analógica (EVA) e dos testes de Finkesltein, Phalen, Phalen reverso, e sinal de Tinel no punho. Resultados A idade média da amostra foi de 22,73 anos, com prevalência de solteiros, de destros, e do sexo feminino. O tempo de uso do smartphone indicado pela maioria dos participantes era entre 5 e 10 anos, e 85% da amostra relatou já ter sentido desconforto no punho e nos dedos durante o uso do aparelho, sendo a dormência o sintoma mais prevalente. Com relação aos testes clínicos, houve prevalência de resultados negativos, e o de Finklestein apresentou maior positividade. Quanto ao BCTQ, dividido em duas escalas, uma de gravidade dos sintomas (escala G) e uma de estado funcional (escala F), a média geral das pontuações foi de 1,61 na escala G, o que indica sintomas de leve a moderados, já a escala F revelou que os sintomas não afetavam a funcionalidade. Conclusão Foi possível observar uma correlação significativa entre o tempo de uso dos smartphones e a presença de desconforto no punho e nos dedos, o que indica que se trata de um fator de risco para o desenvolvimento de morbidades.

Percutaneous Suspensory Stabilization of Chronic Distal Radioulnar Joint (DRUJ) Dislocation Using an Adjustable Loop Endobutton Construct: Case Report / Fixação suspensiva percutânea de luxação crônica da articulação radioulnar distal (ARUD) usando um dispositivo de endobutton de laço ajustável: Relato de caso

Abstract Chronic distal radioulnar joint (DRUJ) dislocation has been treated historically with complex osteotomies and reconstructive procedures, often resulting in intractable stiffness and loss of function. It is desirable to use a technique of fixation that will not only restore the wrist biomechanics but also be cosmetically appealing to the individual. We present a novel technique of reduction and fixation of a chronically dislocated DRUJ in a 26-year-old male using a minimally invasive approach, with successful restoration of DRUJ function and no postoperative complications.

Resumo Luxação crônica da articulação radioulnar distal (ARUD) foi tratada historicamente com osteotomias complexas e procedimentos reconstrutivos, geralmente resultando em rigidez intratável e perda de função. É desejável usar uma técnica de fixação que não apenas restaure a biomecânica do punho, mas também seja esteticamente atraente para o indivíduo. Apresentamos uma nova técnica de redução e fixação de uma ARUD deslocada cronicamente em um homem de 26 anos, usando uma abordagem minimamente invasiva, com restauração bem-sucedida da função da ARUD e sem complicações pós-operatórias.

Anatomical and histomorphometric study of the ulnar nerve at the wrist / Estudio anatómico e histomorfométrico del nervio ulnar en la muñeca

SUMMARY: The ulnar nerve (UN) is the main nerve responsible for innervation of the intrinsic musculature of the hand. It is of great importance to have a deep anatomical knowledge of the UN. The aim of this study is to enrich the knowledge of the UN anatomy at the wrist and provide useful reference information for clinical and surgical applications. In this descriptive cross-sectional study, 44 upper limbs of fresh cadavers were evaluated. The UN, the superficial branch of the ulnar nerve (SBUN), and the deep branch of the ulnar nerve (DBUN) were evaluated. Morphometric variables were measured using a digital caliper, and samples of nervous tissue were taken to evaluate the histomorphometry. Before entering the Guyon's canal, the UN had a diameter of 3.2 ± 0.4 mm. In 36 samples (82 %) the UN presented a bifurcation pattern and in the remaining 8 samples (18 %) a trifurcation was shown. The diameter of the DBUN was 1.9 ± 0.33 mm and that of the SBUN was 1.29 ± 0.22 mm. In the bifurcation patterns, the SBUN had a trunk of 5.71 ± 1.53 mm before bifurcating into the common digital nerve (fourth and fifth fingers) and an ulnar digital collateral nerve (fifth finger). The DBUN had an area of 2.84 ± 0.7 mm2 and was made up of 8 ± 1.4 fascicles and 3595 ± 465 axons. The SBUN area was 1.31 ± 0.27 mm2, it was made up of 6 ± 1.1 fascicles and 2856 ± 362 axons. The reported findings allow the hand surgeon to improve his understanding of the clinical signs of patients with UN pathologies at the wrist level and thus achieve greater precision while planning and performing surgical approaches and dissections.

El nervio ulnar (NU) es el principal nervio responsable de la inervación de la musculatura intrínseca de la mano. Es de gran importancia tener un profundo conocimiento anatómico del NU. El objetivo de este estudio fue enriquecer el conocimiento de la anatomía del NU en la muñeca y proporcionar información de referencia útil para aplicaciones clínicas y quirúrgicas. En este estudio descriptivo transversal se evaluaron 44 miembros superiores de cadáveres frescos. Se evaluó el NU, el ramo superficial del nervio ulnar (RSNU) y el ramo profundo del nervio ulnar (RPNU). Las variables morfométricas se midieron con un caliper digital y se tomaron muestras del nervio para evaluar la histomorfometría. Antes de ingresar al canal del nervio ulnar (canal Guyon), el ONU tenía un diámetro de 3,2 ± 0,4 mm. En 36 muestras (82 %) el ONU presentó un patrón de bifurcación y en las 8 muestras restantes (18 %) se presentó una trifurcación. El diámetro del RPNU fue de 1,9 ± 0,33 mm y el del RSNU de 1,29 ± 0,22 mm. En los patrones de bifurcación, el RSNU presentó un tronco de 5,71 ± 1,53 mm antes de bifurcarse en el nervio digital común (cuarto y quinto dedo) y un nervio digital colateral ulnar (quinto dedo). El RPNU tenía un área de 2,84 ± 0,7 mm2 y estaba formado por 8 ± 1,4 fascículos y 3595 ± 465 axones. El área del RSNU fue de 1,31 ± 0,27 mm2, estaba formado por 6 ± 1,1 fascículos y 2856 ± 362 axones. Los hallazgos reportados permiten al cirujano de mano mejorar su comprensión de los signos clínicos de los pacientes con patologías del NU a nivel de la muñeca y así lograr una mayor precisión en la planificación y realización de abordajes y disecciones quirúrgicas.

Comparison between free wrist crease flap pedicled with superficial palmar branch of radial artery and traditional free toe flap in reconstruction of hand soft tissue defects: A study on clinical efficacy / 中华显微外科杂志

Objective:To compare the difference in clinical efficacy between a free wrist crease flap pedicled with superficial palmar branch of the radial artery flap (SPBRAF) and a traditional free toe flap (TFTF) in reconstruction of hand soft tissue defects, and to provide reference for the treatment of small-to medium-sized hand soft tissue defects.Methods:Data of 37 patients who received hand surgery in Department of Hand Surgery, No.971 Hospital of the PLA Navy from December 2016 to December 2019 for small-to medium-sized hand soft tissue defects were retrospectively studied. Among the 37 patients, there were 32 males and 5 females, aged between 18 and 65 years old, with 41.5 years old in average. According to the reconstructive surgical procedure, patients were divided into SPBRAF group (22 cases) and TFTF group (15 cases). Regular follow-ups were conducted after surgery. The difference in curative effect at the last follow-up between the 2 groups was evaluated by the comparison of data acquired in follow-up. SPSS 25.0 was used to analyse the data statistically. The evaluation indicators included flap survival, long-term recovery of flap, recovery effect at donor site, total active movement(TAM) of the affected digit, time of hospital stay and the time return to work. P<0.05 was considered a statistically significant. Results:All free flaps survived. All patients were entered 6-18 (mean, 10) months of postoperative follow-up to comprehensively evaluate the therapeutic effect. According to the Evaluation Trial Standards of Upper Limb Partial Function of Hand Surgery of Chinese Medical Association, in the SPBRAF group, 20 flaps were found in excellent, and 2 in good; in the TFTF group, 14 flaps were found in excellent, 1 in good. There was no statistical difference between the 2 groups( P>0.05). The colour, texture and thickness of flaps between the 2 groups were either in excellent or good. There was no statistical difference between the 2 groups( P>0.05). TPD in the TFTF group (5-6 mm) was better than that in SPBRAF group (6-7 mm) with statistical difference between the 2 groups ( P<0.05). Texture at donor sites between the 2 groups was either in excellent or good ( P>0.05). In terms of appearance, sensation and recovery time of donor site, it was found that the SPBRAF group(mean, 6 weeks) was significantly better than those in the TFTF group(mean, 8 weeks) and there was statistical difference between the 2 groups ( P<0.05). In terms of recovery of TAM in single-digit, excellent or good were shown in both groups and there was no statistical difference between the 2 groups ( P>0.05). In terms of hospitalisation and time for return to work, the SPBRAF group(mean, 8 days and 17 weeks) was significantly better than that of TFTF group(mean, 12 days and 24 weeks), and there was statistical difference between the 2 groups ( P<0.05). Conclusion:SPBRAF has an ideal effect on reconstruction of small-to medium-sized hand soft tissue defects in hand. Although the flap is still inferior in sensation and appearance compared with the TFTF, the advantages in terms of donor site recovery, patient satisfaction of the donor site and reduced time of hospitalisation and return to original work are more obvious. SPBRAF provides a good complement to surgical procedures reconstructing a digit defect.

Preliminary application of a novel distraction reductor in the surgical treatment of unstable distal radius fractures with metaphyseal volar comminution / 中华创伤骨科杂志

Objective:To evaluate a novel distraction reductor in the surgical treatment of unstable distal radius fractures with metaphyseal volar comminution.Methods:From January 2019 to December 2020, 27 patients with unstable distal radius fracture complicated with metaphyseal volar comminution were treated at Department of Orthopaedics, Zhoupu Hospital Affiliated to Shanghai University of Medicine & Health Sciences. They were 6 males and 21 females, with an age of (69.4±9.4) years. All fractures were unilateral and closed, involving the right side in 17 cases and the left side in 10 cases. All patients were treated by internal fixation with an anatomical locking plate through the volar approach and the novel distraction reductor was used to reduce the fracture ends. Regular imaging examinations were performed to evaluate the reduction, maintenance and union of fractures after surgery. One year after operation, the curative efficacy was assessed by evaluation of the range of wrist motion, Disabilities of the Arm, Shoulder and Hand (DASH) score, Gartland-Werley score and Bartra radiology score.Results:All the operations went on successfully with a duration of (92.3±8.9) min. All the incisions healed primarily. The follow-up time was (15.9±2.9) months. The radial height, palmar tilt, ulnar inclination and articular surface step-off immediately after operation [(11.23±1.51) mm, 12.10°±3.44°, 20.54°±3.44°, and (0.95±0.42) mm] were not significantly lost compared with those one year after operation [(11.22±1.55) mm, 12.07°±3.44°, 20.51°±3.33°, and (0.93±0.40) mm] (all P>0.05). One year after operation, the range of wrist motion was good with dorsiflexion of 59.7°±5.5°, palm flexion of 63.0°±9.1°, pronation of 66.5°±5.5°, supination of 61.2°±5.6°, radial deviation of 22.7°±4.8°, and ulnar deviation of 30.3°±6.1°; DASH score was 13.5±5.5; Bartra radiology score was 88.6±6.5, giving an excellent and good rate of 88.9% (24/27);Gartland-Werley score was 2.7±2.1, giving an excellent and good rate of 92.6% (25/27). Follow-ups observed no poor fracture healing, internal fixation failure, tendon or nerve injury or traumatic arthritis. Conclusion:In the surgical treatment of unstable distal radius fractures with metaphyseal volar comminution, the novel distraction reductor can lead to ideal reduction of displaced fractures and effectively correct the shortening caused by volar cortex comminution to achieve satisfactory functional effects in clinic.

Research progress in the diagnosis and treatment of radiocarpal fracture-dislocation / 中华创伤杂志

Radiocarpal fracture-dislocation (RFD) is a rare injury normally associated with the destruction of bones, joints and ligaments. The improper diagnosis and treatment of RFD will cause severe complications and affect the long-term function of wrist joints. The difficulties of clinical diagnosis and treatment lie in the accurate diagnosis, identification and reconstruction of the structure of specific injury. As the foreign and domestic literatures are mainly case analyses or systemic case reports rather than large-scale reports, there still lacks a systemic knowledge of the standard diagnosis and treatment of RFD clinically, thus leading to problems such as missed diagnosed or misdiagnosed, improper application of treatment methods and incomplete reconstruction. Therefore, the authors reviewed relevant literatures about the features, diagnosis and treatment of RFD, in order to provide references for the clinical diagnosis and treatment of RFD.

Wrist-ankle acupuncture combined with rehabilitation for dysphagia caused by achalasia of cricopharyngeal muscle after stroke / 中国基层医药

Objective:To investigate the clinical efficacy of wrist-ankle acupuncture combined with rehabilitation for dysphagia caused by achalasia of the cricopharyngeal muscle after stroke.Methods:Sixty patients with dysphagia caused by achalasia of the cricopharyngeal muscle after stroke who received treatment in Wenzhou Hospital of Traditional Chinese Medicine from June 2019 to March 2020 were included in this study. They were randomly divided into a treatment group and a control group ( n = 30). All patients received routine drug treatment and swallowing rehabilitation training. The control group underwent routine acupuncture treatment. The treatment group received wrist-ankle acupuncture based on routine acupuncture treatment. Both groups were treated for 4 consecutive weeks. The clinical efficacy in the two groups was evaluated using the Video Fluoroscopic Swallowing Study (VFSS), Standardized Swallowing Assessment (SSA), and Swallow Quality-of-Life Questionnaire (SWAL-QOL). Results:Before treatment, there were no significant differences in VFSS, SSA, and SWAL-QOL scores between the two groups. After treatment, VFSS, SSA, and SWAL-QOL scores in the treatment group were (8.21 ± 0.77) points, (21.19 ± 1.42) points, (200.24 ± 11.12) points, and they were (6.01 ± 0.36) points, (23.31 ± 1.45) points, and (182.37 ± 12.06) points in the control group ( t = 3.26, 5.50, 6.31, all P < 0.05). Conclusion:Wrist-ankle acupuncture combined with rehabilitation is an effective treatment method for dysphagia caused by achalasia of the cricopharyngeal muscle after stroke. It can alleviate dysphagia and improve quality of life.

Curative effect of wrist-ankle acupuncture on postpartum abdominal pain and its influence on serum β-EP level in puerpera / 中国针灸

OBJECTIVES@#To observe the clinical effect of wrist-ankle acupuncture on postpartum abdominal pain and its influence on serum beta-endorphin (β-EP) level in puerpera.@*METHODS@#Seventy patients with postpartum abdominal pain were randomly divided into an acupuncture + herbal medication group (35 cases, 1 case dropped out) and a herbal medication group (35 cases, 2 cases dropped out). In the herbal medication group, 1 day after delivery, modified shenghua decoction was taken orally, one dose a day. In the acupuncture + herbal medication group, on the basis of herbal medication, wrist-ankle acupuncture was given at the Lower 1 and Lower 2 of the ankles, once daily. The duration of treatment was 3 days in the two groups. Before and after treatment, the score of visual analogue scale (VAS) for pain, serum β-EP level, uterine fundus height, postpartum conditions of lochia and the uterine recovery at 42 days postpartum were compared in the patients of the two groups.@*RESULTS@#At each time point after treatment (24 h, 48 h and 72 h after delivery), VAS scores and the uterine fundus height were reduced as compared with those before treatment (2 h after delivery) in the two groups (P<0.05); these indexes in the acupuncture + herbal medication group were lower than those in the herbal medication group (P<0.05). After treatment (72 h after delivery), β-EP levels in the serum were increased when compared with those before treatment in the two groups (P<0.05), and the β-EP level in the acupuncture + herbal medication group was higher than that in the herbal medication group (P<0.05). The volume of postpartum lochia discharge in the acupuncture + herbal medication group was higher than that in the herbal medication group (P<0.05), while the duration of postpartum lochia discharge and the total time of lochia discharge were shorter (P<0.05). Regarding the recovery of the uterus at 42 days postpartum, there was no statistical significance between the two groups (P>0.05).@*CONCLUSIONS@#Wrist-ankle acupuncture obviously reduces the degree of postpartum abdominal pain and promotes the lochia discharge and the uterine recovery. The effect mechanism may be related to the up-regulation of serum β-EP level and the increase of pain threshold so that analgesia is obtained.

Concomitant Ulnar Styloid Fractures in Distal Radius Osteosynthesis Does Not Impact Radiographic Outcomes, Ulnar Sided Symptoms and Patient Outcomes

@#Introduction: Current literature reports varied significance of ulnar styloid fractures (USF) associated with distal radius fractures. Our study assesses the role of ulnar styloid fractures and fragment size in surgically managed distal radius fractures. Materials and methods: We reviewed patients who underwent surgical fixation of distal radius fractures between January 2004 to June 2006. Patients were divided into those with (Group 1) and without (Group 0) USFs. Post-operative radiographic parameters, clinical outcomes and overall wrist function were analysed. Outcomes included ulnar-sided wrist pain, extensor carpi ulnaris (ECU) tendinitis, triangular fibrocartilage complex (TFCC) grind test, distal radioulnar joint (DRUJ) instability and pain. Overall wrist function was assessed with range of motion and Disabilities of the Arm, Shoulder and Hand (DASH) score. Results: Our study cohort included 31 males and 23 females, and 38.9% of these patients had concomitant USFs. There was no difference in terms of demographic data and fracture configuration between groups. Radiographic parameters were similar, except for palmar tilt, which was significantly higher in Group 1 (4.6º vs 9.4º, p=0.047). At 24 months, there were no differences in clinical outcomes and overall wrist function. A sub-group analysis showed that mean USF fragment size was larger in patients with a positive TFCC grind test (3.9mm vs 7.3mm, p=0.033). Conclusion: The presence of USFs in surgically managed distal radius fractures does not compromise clinical and functional outcome. Similarly, the size of USFs does not impact clinical and functional outcome but is associated with the presence of a positive TFCC grind test.

Association between wrist pain and awkward postures among workers in 10 key industries / 环境与职业医学

Background Prolonged awkward postures during occupational activities can lead to excessive musculoskeletal load on the wrist of workers and symptoms such as wrist pain or discomfort. Objective To survey the prevalence of wrist pain among workers in 10 key industries and analyze its correlation with wrist working postures. Methods By using stratified cluster sampling method, workers from 10 key industries, such as footwear manufacturing industry, shipbuilding manufacturing industry, and automobile manufacturing industry, were selected from seven regions in North China, East China, Central China, South China, Southwest China, Northwest China, and Northeast China. The demographic information, wrist working postures, pain in wrist of the workers were collected through a cross-sectional survey. Pearson χ2 test was used to compare prevalence by selected factors, trend χ2 test for between group comparison, and unconditional logistic regression models for the association of wrist working postures with wrist pain. Results There were 64052 workers enrolled in this survey, and 56286 provided valid questionnaires (the effective rate was 87.8%). According to the survey, the prevalence of wrist pain was 23.3% (13112/56286), and the industries with higher prevalences were footwear manufacturing (27.1%, 1927/7106), automobile manufacturing (24.9%, 5378/21560), and shipbuilding and related equipment manufacturing (24.4%, 850/3488) industries. Finger pinching (OR=2.09, 95%CI: 1.95-2.24), frequent wrist bending (OR=2.03, 95%CI: 1.92-2.15), fixed wrist bending (OR=1.77, 95%CI: 1.69-1.85), wrist on hard edge (OR=1.34, 95%CI: 1.28-1.40), and arms over shoulders (OR=1.11, 95%CI: 1.05-1.17) increased the risk of reporting wrist pain. Conclusion Awkward postures are related to wrist pain among workers in selected 10 key industries. The related factors are wrist on hard edge, frequent wrist bending, finger pinching, fixed wrist bending, and arms over shoulders.

Influencing factors and attribution analysis of hand/wrist musculoskeletal disorders among welders in an automobile factory / 环境与职业医学

Background Welders in automobile manufacturers are prone to hand/wrist musculoskeletal disorders (MSDs), which seriously affect workers' physical and mental health. Objective To investigate the factors influencing hand/wrist MSDs of welders in an automobile factory and the population attributable risk percentage (PARP). Methods Five branches of an automobile factory were selected by convenient sampling method, and all qualified welders in the selected branches were enrolled as research participants. The Chinese Musculoskeletal Disorders Questionnaire was used to collect information such as general characteristics of welders, presentation of MSDs in the wrists and hands, and selected ergonomic factors. Log-binomial model in the SAS program was used to calculate the prevalence ratio (PR) of each influencing factor and PARP. Results The prevalence rate of MSDs in the hands/wrists of welders in the automobile factory was 44.1% (345/782). The results of multiple analysis showed that female (PR=1.25, 95%CI: 1.10-1.44), being very tired after work (versus not tired, PR=2.22, 95%CI: 1.16-4.25), twisting wrists (PR=1.44, 95%CI: 1.19-1.74), insufficient operating space (PR=1.22, 95%CI: 1.07-1.40), and holding or pinching objects by hands (PR=1.58, 95%CI: 1.18-2.12) increased the risk of reporting hand/wrist MSDs symptoms. The PARP of major occupational risk factors was: holding or pinching objects by hands, 32.46%; twisting wrists, 21.50%; being very tired after work, 15.28%; and insufficient operating space, 8.18%. Conclusion The prevalence of MSDs symptoms in hands/wrists of welders in this automobile factory is high. Gender, holding or pinching objects by hands, twisting wrists, being very tired after work, and insufficient operating space are the factors affecting hand/wrist MSDs, among which holding or pinching objects by hands and twisting wrists are the priority intervention factors.

Clinical analysis of distal radius core decompression for chronic wrist pain / 中国修复重建外科杂志

OBJECTIVE@#To investigate the effectiveness of distal radius core decompression in the treatment of chronic wrist pain caused by various etiologies.@*METHODS@#A retrospective analysis was performed for the clinical data of 10 patients with chronic wrist pain treated with distal radial core decompression between January 2018 and December 2021. There were 6 males and 4 females with an average age of 37.4 years (range, 21-55 years). The disease duration ranged from 7 to 72 months, with an average of 26.5 months. Preoperative MRI examination showed that 10 cases had bone marrow edema at the distal radius on the affected side, and 8 cases had bone marrow edema in the carpal bones such as scaphoid and lunate bone. Among them, 3 patients had a history of wrist fracture, and 2 patients had Kienböck diseases (1 case each in stage ⅡB and stage ⅢA). Three cases were combined with triangular fibrocartilage complex (TFCC) type 1A injury. Two cases were combined with osteoarthritis, 1 of them was complicated with severe traumatic arthritis, the wrist arthroscopy showed that the TFCC was completely lost and could not be repaired, and the cartilage of the lunate bone and the ulnar head were severely worn.Visual analogue scale (VAS) score was used to evaluate the relief of wrist pain before operation, at 6 months after operation, and at last follow-up, and the range of motion of the affected wrist in dorsiflexion, palmar flexion, ulnar deviation, and radial deviation was measured. The degree of bone marrow edema was evaluated according to T1WI, T2WI, and STIR sequences of MRI.@*RESULTS@#All the patients were followed up 12-22 months, with an average of 16.4 months. Except for 1 patient who experienced persistent wrist joint pain and limited mobility after operation, the remaining 9 patients showed significant improvement in pain symptoms and wrist joint mobility. The VAS score and range of motion of wrist dorsiflexion, palmar flexion, ulnar deviation, and radial deviation at 6 months after operation and at last follow-up were significantly improved when compared with those before operation, the VAS score and the range of motion of wrist ulnar deviation and radial deviation at last follow-up were further improved when compared with those at 6 months after operation, all showing significant differences ( P<0.05). There was no significant difference in wrist dorsiflexion and palmar flexion between at 6 months after operation and at last follow-up ( P>0.05). Bone marrow edema was improved in 6 patients on MRI at 6 months after operation, and was also improved in other patients at last follow-up.@*CONCLUSION@#For chronic wrist pain caused by a variety of causes, distal radius core decompression can directly reduce the pressure of the medullary cavity of the distal radius, improve the blood supply of the corresponding distal structure, significantly alleviate chronic wrist pain, and provide an option for clinical treatment.

Discussion on the relationship between yuan-source points of yang meridians and diseases of fu- organs / 中国针灸

Huangdi Neijing (Yellow Emperor 's Canon of Medicine) establishes the theory that yuan-source points are indicated in zangfu diseases. However, compared with the yuan-source points of yin meridians for the treatment of zang-organ diseases, there is less attention to the indication of yuan-source points of yang meridians for fu-organ diseases, and this statement is even questioned. Collating the early literature and associating with the researches of medical experts, it is found that Nanjing (Classic of Difficult Questions) should be the theoretic origin that yuan-source points of yang meridians are indicated in fu-organ diseases. Regarding the reasons why this theory has not received clinical attention, the three aspects are involved, i.e. the theoretic completion of "he-sea points of three-foot-yang meridians for the diseases of six fu-organs", the limitation of the theory itself, and the lack of literature materials. It is proposed that the exploration on this theory should be deepened in views of the essence of yuan-source points relevant with the characteristic of the wrist-ankle pulse palpation region, acupoint combination, modern technology, etc.

Treatment duration of wrist-ankle acupuncture for relieving post-thyroidectomy pain: A randomized controlled trial / 中西医结合学报

BACKGROUND@#Treatment duration of wrist-ankle acupuncture (WAA) is uncertain for post-thyroidectomy pain relief.@*OBJECTIVE@#This study evaluated the effect of different WAA treatment duration on post-operative pain relief and other discomforts associated with thyroidectomy.@*DESIGN, SETTING, PARTICIPANTS AND INTERVENTION@#This randomized controlled trial was conducted at a single research site in Guangzhou, China. A total of 132 patients receiving thyroidectomy were randomly divided into the control group (sham WAA, 30 min) and three intervention groups (group 1: WAA, 30 min; group 2: WAA, 45 min; group 3: WAA, 60 min), with group allocation ratio of 1:1:1:1. Acupuncture was administered within 1 hour of leaving the operating room.@*OUTCOMES AND MEASURES@#Primary outcome was patients' pain at the surgical site assessed by visual analogue scale (VAS) at the moment after acupuncture treatment (post-intervention). Secondary outcomes included the patients' pain VAS scores at 6, 12, 24, 48 and 72 h after the thyroidectomy, the 40-item Quality of Recovery (QoR-40) score, the grade of post-operative nausea and vomiting (PONV), and the use of additional analgesic therapy.@*RESULTS@#The adjusted mean difference (AMD) in VAS scores from baseline to post-intervention in group 1 was -0.89 (95% confidence interval [CI], -1.02 to -0.76). The decrease in VAS score at post-intervention was statistically significant in group 1 compared to the control group (AMD, -0.43; 95% CI, -0.58 to -0.28; P < 0.001), and in groups 2 and 3 compared to group 1 (group 2 vs group 1: AMD, -0.65; 95% CI, -0.81 to -0.48; P < 0.001; group 3 vs group 1: AMD, -0.66; 95% CI, -0.86 to -0.47; P < 0.001). The VAS scores in the four groups converged beyond 24 h after the operation. Fewer patients in group 2 and group 3 experienced PONV in the first 24 h after operation. No statistical differences were measured in QoR-40 score and the number of patients with additional analgesic therapy.@*CONCLUSION@#Compared with the 30 min intervention, WAA treatment with longer needle retention time (45 or 60 min) had an advantage in pain relief within 6 h after surgery. WAA's analgesic effect lasted for 6-12 h post-operatively. Please cite this article as: Han XR, Yue W, Chen HC, He W, Luo JH, Chen SX, Liu N, Yang M.
