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.

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.

Gartland and Werley scores was (1.1±0.4) at 12 months afteropertaion, and 27 patients got excellent result and 3 good.@*CONCLUSION@#Dorsal plate assisted fixation of dorsal lunate fossa fractures is beneficial to reduction and stabilization of displaced dorsal fractures and restoration of palmar inclination.

Adaptive repetitive control of wrist tremor suppression based on functional electrical stimulation / 生物医学工程学杂志

Tremor is an involuntary and repetitive swinging movement of limb, which can be regarded as a periodic disturbance in tremor suppression system based on functional electrical stimulation (FES). Therefore, using repetitive controller to adjust the level and timing of FES applied to the corresponding muscles, so as to generate the muscle torque opposite to the tremor motion, is a feasible means of tremor suppression. At present, most repetitive control systems based on FES assume that tremor is a fixed single frequency signal, but in fact, tremor may be a multi-frequency signal and the tremor frequency also varies with time. In this paper, the tremor data of intention tremor patients are analyzed from the perspective of frequency, and an adaptive repetitive controller with internal model switching is proposed to suppress tremor signals with different frequencies. Simulation and experimental results show that the proposed adaptive repetitive controller based on parallel multiple internal models and series high-order internal model switching can suppress tremor by up to 84.98% on average, which is a significant improvement compared to the traditional single internal model repetitive controller and filter based feedback controller. Therefore, the adaptive repetitive control method based on FES proposed in this paper can effectively address the issue of wrist intention tremor in patients, and can offer valuable technical support for the rehabilitation of patients with subsequent motor dysfunction.

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.

Design and application of wrist restraint gloves suitable for patients with agitation / 中华危重病急救医学

Patients in the intensive care unit (ICU) often need to have various catheters placed on their bodies due to their severe condition. In order to prevent the occurrence of unplanned extubation, patients' hands should be restrained appropriately. The current restraint gloves used in clinical practice have problems such as improper restraint, easy falling off of oxygen saturation monitoring probes, and pressure injury of hands. Therefore, department of critical care medicine, Affiliated Hangzhou First People's Hospital, Zhejiang University School of Medicine designed a wrist restraint glove suitable for restless patients, and obtained the national utility model patent (ZL 2020 2 1612453.7). The device is composed of restraint gloves and restraint rings, which can not only restrain patients, but also continuously monitor the changes of blood oxygen saturation in patients with restfulness. This device is convenient to use, low cost, comfortable to wear, and can prevent the occurrence of device-related pressure injuries, which is suitable for clinical application.

According to the intraoperative method of placement of cannulated screw, they were divided into Guide group(16 patients)and Conventional group(12 patients). There were 13 males and 3 females in Guide group, aged from 20 to 60 years old with an average of(31.42±9.71)years old;5 patients were classified as type A2, 3 patients were classified as type B1 and 8 patients were classified as type B2 according to Herbert classification;they were treated with percutaneous cannulated compression screw fixation under the guidance of needle. There were 11 males and 1 female in Conventional group, aged from 23 to 61 years old with an average of(30.51±7.52)years old;5 patients were classified as type A2, 2 patients were classified as type B1 and 5 patients were classified as type B2 according to Herbert classification;they were treated with conventional percutaneous cannulated compression screw fixation. The operation time, screw angle relative to the longitudinal axis of the scaphoid and wrist function score were assessed and compared between the two groups.@*RESULTS@#A total of 28 patients were followed up from 20 to 45 months with an average of (33.00±8.72) months. None of patients had intraoperative complication and incision infection. These patients returned to work gradually 2 weeks after operation, and all fractures healed within 12 weeks. The operation time in the Guide group was significantly less than that in the Conventinal group(P<0.05). Screw angle relative to the longitudinal axis of the scaphoid in the Guide group was significantly smaller than that in the Conventional group(P<0.05). There was no significant difference in Mayo wrist function scores at the last follow-up between the two groups(P>0.05). During the follow-up period, none of the 28 patients showed internal fixation displacement, arthritis, scaphoid necrosis and other complications.@*CONCLUSION@#In the treatment of acute non-displaced scaphoid fractures, the operation time of needle-guided percutaneous cannulated headless compression screw fixation is significantly shorter than that of conventional percutaneous screw fixation, and the screw axis is easier to be parallel to the longitudinal axis of the scaphoid.

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.

Effect of Wrist-Ankle Acupuncture on Postoperative Analgesia after Total Knee Arthroplasty / 中国结合医学杂志

OBJECTIVE@#To evaluate the effect of wrist-ankle acupuncture (WAA) in pain and functional recovery after total knee arthroplasty (TKA).@*METHODS@#From June to September 2020, 94 participants were included from the Second Hospital of Tangshan and randomly assigned to the WAA group (47 cases) and the sham WAA group (47 cases) by a random number table, receiving real or sham WAA treatment, respectively. The primary outcome measure involved the visual analogue scale (VAS) scores at rest and in motion. The secondary outcomes involved the range of motion (ROM) of the knee joints, straight-leg raising time, postoperative weight-bearing time, sufentanil consumption within 48 h of patient-controlled analgesia (PCA) pump, length of hospital stay, and postoperative complications.@*RESULTS@#The VAS scores on the 3rd, 5th, and 7th postoperative days at rest and in motion was significantly lower in the WAA group than that of the sham WAA group (P<0.01). The ROM on the 1st, 2nd, and 3rd PODs was significantly higher in the WAA group than that of the sham WAA group (P<0.01). In comparison to the sham WAA group, the sufentanil consumption within 48 h of PCA pump was significantly less in the WAA group (156.3 ± 12.2 µg vs. 128.8 ± 9.8 µg, P<0.01). There was no significant difference in active straight-leg raising time, postoperative weight-bearing time, length of hospital stay, and postoperative complications between the two groups (P>0.05).@*CONCLUSIONS@#WAA could alleviate post-TKA pain, improve knee joint function, and reduce the sufentanil consumption within 48 h of PCA pump. WAA is a safe and effective treatment in the perioperative analgesic management for TKA.

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.

Introduction: Currently, the use of local anaesthetic with no tourniquet and wide awake patient (Wide Awake Local Anaesthetic No Tourniquet - WALANT) has gained popularity in surgeries of the hand and wrist. Objective: To report our experience in the use of WALANT technique in order to discard the use of tourniquet in hand surgeries. Method: In November 2020, thirty patients underwent surgery due to different orthopaedic conditions, among them trigger fingers, carpal tunnel syndrome, stenosing tenovaginitis of the thumb, carpal ganglion and amputation of the third radius due to post trauma stiffness, among others. In order to assess this technique, we considered surgical time, volume of bleeding, pain during anesthetic infiltration, intervention and the need for additional anesthetic during the first 24 hours after surgery; we considered also ischemia, complications and level patient´s satisfaction. Results: This technique had similar results to others; however, the bleeding is mild, there is no need for ischemia, the surgical time is lesser and the anesthetic effect lasted 10 to 12 hours in all patients. None of them required additional anesthetic. All subjects felt the initial infiltration but none complained of pain during the rest of the anesthetic injection or during the surgical act. There were no complications. Conclusions: The effectiveness of WALANT technique in hand surgeries is shown. The cost of materials for the surgical act is reduced with it, as well as the surgical staff, it is easy to use and unpleasant sensations and dangers of the use of ischemia in patients are reduced(AU)

Clinical observation on wrist-ankle acupuncture for shoulder-hand syndrome phaseⅠafter stroke / 中国针灸

OBJECTIVE@#To compare the clinical efficacy between wrist-ankle acupuncture and conventional acupuncture on shoulder-hand syndrome (SHS) phaseⅠafter stroke.@*METHODS@#A total of 64 patients with SHS phaseⅠafter stroke were randomized into a wrist-ankle acupuncture group and a conventional acupuncture group, 32 cases in each group. On the basis treatment of internal medicine and conventional rehabilitation, wrist-ankle acupuncture was applied at upper 4 area, upper 5 area and upper 6 area on the affected side in the wrist-ankle acupuncture group, while acupuncture was applied at Jianyu (LI 15), Quchi (LI 11), Shousanli (LI 10), etc. on the affected side in the conventional acupuncture group. The treatment was given 30 min each time, once a day, 5 days a week for 3 weeks in both groups. Before and after treatment, the visual analogue scale (VAS) score, degree of hand swelling, shoulder-hand syndrome scale (SHSS) score, Fugl-Meyer assessment for upper extremity (FMA-UE) score and modified Barthel index (MBI) score were observed, and the clinical therapeutic effect was evaluated in both groups.@*RESULTS@#After treatment, the VAS scores, degree of hand swelling and SHSS scores were decreased (P<0.05), and the FMA-UE scores and MBI scores were increased (P<0.05) compared before treatment in both groups; in the wrist-ankle acupuncture group, the VAS score, degree of hand swelling and SHSS score were lower (P<0.05), and the FMA-UE score and MBI score were higher (P<0.05) than those in the conventional acupuncture group. The total effective rate was 96.9% (31/32) in the wrist-ankle acupuncture group, which was superior to 90.6% (29/32) in the conventional acupuncture group (P<0.05).@*CONCLUSION@#Wrist-ankle acupuncture can effectively relieve pain and hand swelling, improve motor function of upper extremity and self-care ability of daily life in patients with shoulder-hand syndrome phaseⅠafter stroke, the therapeutic effect is superior to conventional acupuncture.

Comparação entre processamentos de dados do acelerômetro gt3x+ para atividade física moderada e vigorosa / Comparison between data processing from gt3x+ accelerometer for vigorous and moderate physical activity

RESUMO O uso do acelerômetro para mensurar a atividade física em pesquisas epidemiológicas, apresenta desafios para aumentar a comparabilidade entre os estudos que utilizam esse equipamento. Nesse sentido o objetivo deste trabalho é comparar estimativas de tempo em AFMV para adultos provenientes de diferentes métodos de processamentos de dados, através do acelerômetro Actigraph GT3X+. Trata-se de um estudo transversal, da linha de base do estudo piloto do Estudo Longitudinal dos Determinantes da Atividade Física. Amostra contou com 31 funcionários terceirizados de ambos os sexos, com idade média de 47.05anos (DP=9.35). Os participantes utilizaram acelerômetros do modelo GT3X+ durante sete dias consecutivos. A estimativa de tempo de AFMV foi gerada através de software Actilife e R-package GGIR. Análises estatísticas descritivas, ANOVA e pos-hoc de Bonferroni para comparabilidade foram realizadas no software R. Análise de Bland-Altman foi realizado no SigmaPlot para avaliação de viés e concordância. Houve diferença significativa no tempo médio de AFMV entre os dados baseados em counts e dados brutos (p<0,001). O tempo médio em AFMV foi menor a partir do processamento por dados brutos do que o em counts (-264,81min/dia; p<0,001). Concluindo que os achados sugerem não haver, estatisticamente, equivalência entre os métodos comparados para estimar tempo de AFMV.

ABSTRACT The use of accelerometers to measure physical activity in epidemiological research presents challenges to increase comparability between studies that use this equipment. In this sense, the objective of this work is to compare time estimates in MVPA for adults from different data processing methods, using the Actigraph GT3X+ accelerometer. This is a cross-sectional study, from the baseline of the pilot study of the Longitudinal Study of the Determinants of Physical Activity. Sample had 31 outsourced employees of both genders, with an average age of 47.05 years (SD=9.35). Participants used GT3X+ model accelerometers for seven consecutive days. The MVPA time estimate was generated using Actilife and R-package GGIR software. Descriptive statistical analyses, ANOVA and Bonferroni post-hoc for comparability were performed in the R software. Bland-Altman analysis was performed in SigmaPlot to assess bias and agreement. There was a significant difference in the mean time of MVPA between count-based data and raw data (p<0.001). The average time in MVPA was shorter from processing by raw data than in counts (-264.81 min/day; p<0.001). Concluding that the findings suggest that there is no statistically equivalence between the methods compared to estimate MVPA time.

Variantes anatómicas del tubérculo de Lister. Presentación de una clasificación imagenológica y su utilidad clínica / Anatomical variants of Lister's tubercle. Presentation of an imaging classification and its clinical utility

Objetivo: Evaluar, en forma retrospectiva, las diferentes variantes de los tubérculos de Lister y el extensor largo del pulgar en imágenes de resonancia magnética de muñecas y, sobre la base de dichos hallazgos, proponer variables a la clasificación. Materiales y métodos: Estudio retrospectivo utilizando imágenes de resonancia magnética entre el 1 de marzo y el 10 de noviembre de 2019. Se incluyeron imágenes de muñeca de pacientes sanos (cortes axiales, sagitales y coronales de 1 mm de espesor), >18 años, sin fractura de muñeca o del carpo, previa o actual, y se excluyó a quienes no cumplían estos criterios. Se analizaron el tubérculo de Lister, la altura de los picos radial y cubital, el ángulo, la longitud del tubérculo, la profundidad de los valles y la altura del tabique. Se evaluó el extensor largo del pulgar analizando la altura, el espesor, la superficie y la presencia o no inflamación asociada. Resultados: Se analizaron 500 imágenes de muñeca, y se obtuvieron 11 subtipos de tubérculo de Lister: 411 tipo 1, 58 tipo 2 y 26 tipo 3. Dentro de estos, el más frecuente fue el tipo 1B. El 26,6% tenía inflamación asintomática en el tercero y cuarto compartimento. Conclusiones: El tubérculo de Lister es importante en muchos procedimientos y sirve como punto de referencia anatómico; por lo tanto, es preciso conocer su patrón más frecuente y sus variantes anatómicas. Proponemos una ampliación de la clasificación, adicionando nuevos tipos de tubérculo por conocer y su relación con el extensor largo del pulgar. Nivel de Evidencia: IV

Objective: To retrospectively evaluate the different variants of Lister's tubercle (LT) and extensor pollicis longus (EPL) using magnetic resonance imaging (MRI) of the wrists, and based on these findings propose variables for classification. Materials and Methods: Retrospective study using images from MRI database files between 03/01/19 to 11/10/19. We included MRI of the wrist of healthy patients (axial, sagittal, and coronal slices of 1 mm thickness) who were older than 18 years, with no history of previous or current wrist or carpal fracture, excluding those who did not meet these criteria. We analyzed LT, height of the radial and ulnar peaks, the angle, tubercle length, depth of the grooves and septum height. We evaluated the EPL, analyzing the height, thickness, surface, and presence of associated inflammation. Results: We evaluated 500 MRI of the wrist, obtaining 11 different subtypes of LT. We found 411 type 1 Lister tubercles, 58 type 2, and 26 type 3. Among these, the most frequent were types 1b. 26.6% presented asymptomatic inflammation in 3rd and 4th compartments. Conclusion: Lister's tubercle is of importance in many procedures and serves as an anatomical landmark, meriting to know its most frequent pattern and its anatomical variants. We propose an extension of the classification, adding new types of tubercles to be known and their relationship with the EPL. Level of Evidence: IV
