Os indivíduos canhotos necessitam de utensílios para concretização de suas atividades diárias, bem como, para o exercício da prática odontológica onde a escassez de equipamentos específicos pode refletir em desgaste corporal, com isso, o presente trabalho tem por objetivo identificar os estudantes canhotos do curso de Odontologia da Universidade Federal de Uberlândia além de identificar suas dificuldades, queixas e locais de dores osteomusculares nas atividades laboratoriais e clínicas. Métodos: Foram incluídos todos os alunos canhotos matriculados no ano de 2021. Foram aplicados questionários on line para coletar os dados dos alunos. Resultados: Foram tabulados e como resultados, encontrou-se que os canhotos representam 5,6% do total de alunos do curso de Odontologia, a maioria são mulheres (66,7%), com média de idade de 21 anos. O segundo período foi o que apresentou maior número de canhotos (25%). As atividades práticas do curso, estas foram cursadas por 91,7% dos entrevistados, que relataram com maior frequência usar a mão esquerda (62,5%), sentar na posição de 1 hora (20,8%) e ter maior dificuldade ao tratar o quadrante superior direito (45,8%). Os locais mais citados de dores osteomusculares após realizar essas atividades, foram: punhos e mãos (62,5%), parte inferior das costas (62,5%) e pescoço (58,3%). Conclusão: Os canhotos representam a minoria dos alunos e suas dificuldades são, a falta de estrutura física adequada e a incompreensão das pessoas ao redor. Em relação a queixa de dor ou desconforto, mãos, punhos, parte inferior das costas e pescoço foram os membros mais citados no estudo(AU)

Left-handed individuals need tools to carry out their daily activities, as well as for the exercise of dental practice where the scarcity of specific equipment can reflect on body wear, with this, the present work aims to identify left-handed students of the course of Dentistry at the Federal University of Uberlândia, in addition to identifying their difficulties, complaints and sites of musculoskeletal pain in laboratory and clinical activities. Methods: All left-handed students enrolled in the year 2021 were included, and three questionnaires were applied online to identify the profile of students and the difficulties encountered in laboratory and clinical practice. Results: They were tabulated and as a result, it was found that left-handers represent 5.6% of the total number of students in the Dentistry course, most of them are women (66.7%), with a mean age of 21 years. The second period was the one with the highest number of left-handers (25%). The practical activities of the course were carried out by 91.7% of the interviewees, who reported more frequently using their left hand (62.5%), sitting in the 1 o'clock position (20.8%) and having greater difficulty when treat the upper right quadrant (45.8%). The most cited sites of musculoskeletal pain after performing these activities were: wrists and hands (62.5%), lower back (62.5%) and neck (58.3%). Conclusion: Lefthanded people represent the minority of students, and their difficulties are the lack of adequate physical structure and the misunderstanding of the people around them. In relation to complaints of pain or discomfort, hands, wrists, lower back and neck were the most cited members in the study(AU)

OBJECTIVE@#To evaluate the clinical features, laboratory and imaging results, treatment and outcomes of eosinophilic fasciitis (EF) and assess the value of ultrasound in the diagnosis of EF.@*METHODS@#We retrospectively analyzed the clinical data of 45 patients with EF treated in our center from January 1, 2006 to February 28, 2022. The consistency between the diagnoses of EF based on ultrasound and MRI findings was assessed.@*RESULTS@#In the 45 EF patients (male/female ratio 3.5:1), the age of onset ranged from 16 to 64 years with a mean disease course of 22.6 months. The average time from symptom onset to diagnosis was 16 months. The most common possible trigger of the disease was vigorous exercise (10/45), causing symmetrical lesions in the limbs, most commonly in the forearms (86.7%) and lower legs (80%). Clinical features of EF included subcutaneous swelling and induration (95.6%), arthralgia and arthritis (55.6%), groove sign (42.2%), hand joint contractures (42.2%), skin pigmentation (37.8%), and peau d'orange appearance (13.3%). Eosinophilia was found in 31 patients (68.9%). Hypergammaglobulinemia was seen in 23/44 (52.3%) and positive antinuclear antibodies in 9 (20%) of the patients. Twentyone of the patients were treated with high-dose methylprednisolone (≥200 mg daily for 3 to 5 consecutive days), and compared with the patients who did not receive this treatment, these patients more frequently experienced relapse before admission, had more extensive involvement, and had a higher rate of hypergammaglobulinemia without fever, but these differences were not statistically significant. Of the 31 patients (68.9%) with follow-up data (for a median of 3.2 years [range 0.2-15.9]), complete remission was achieved in 12 (38.7%) patients, and the accumulative complete remission rate was 44.1% at 5.5 years. No specific baseline characteristics or immunosuppressants were found to correlate with the treatment response. A total of 26 patients underwent both ultrasound and MRI examination, and the Kappa value of the diagnostic results between ultrasound and MRI was 0.91.@*CONCLUSION@#EF is characterized by symmetrical subcutaneous swelling and induration in the limbs, accompanied by eosinophilia and hypergammaglobulinemia. Glucocorticoid is effective for treating EF. Ultrasound examination can identify thickening of subcutaneous fascia for an early diagnosis of EF.

In clinical practice, radiopharmaceutical dynamic imaging technology requires the bolus injection method to complete injection. Due to the failure rate and radiation damage of manual injection, even experienced technicians still bear a lot of psychological burden. This study combined the advantages and disadvantages of various manual injection modes to develop the radiopharmaceutical bolus injector, and explored the application of automatic injection in the field of bolus injection from four aspects: radiation protection, occlusion response, sterility of injection process and effect of bolus injection. Compared with the current mainstream manual injection method, the bolus manufactured by the radiopharmaceutical bolus injector based on the automatic hemostasis method had a narrower full width at half maximum and better repeatability. At the same time, radiopharmaceutical bolus injector had reduced the radiation dose of the technician's palm by 98.8%, and ensured more efficient vein occlusion recognition performance and sterility of the entire injection process. The radiopharmaceutical bolus injector based on automatic hemostasis has application potential in improving the effect and repeatability of bolus injection.

OBJECTIVE@#This study aims to clarify how the stimulation of acupuncture points is achieved by needles with different surface texture during acupuncture; it also seeks to lessen injury at the insertion site and increase the therapeutic efficacy of acupuncture, by simulating the mechanical effects of various needle surface patterns on Zusanli (ST36) without changing the radius of acupuncture needles.@*METHODS@#Five acupuncture needle models with different surface patterns, including the smooth needle, the lined needle, the ringed needle, the left-hand threaded needle and the right-hand threaded needle, and a layered model of the Zusanli acupoint were used to investigate how to reduce tissue damage and increase stimulation during acupuncture treatment. Puncturing of the skin as well as lifting-inserting and twisting needle manipulations were simulated using these models, and the degree of damage and force of stimulation caused by the acupuncture needles with different surface patterns during acupuncture were compared.@*RESULTS@#The smooth needle and the lined needle caused the least tissue damage during insertion, while the left-hand threaded and the right-hand threaded needles caused the most damage. The ringed needle, the left-hand threaded needle and the right-hand threaded needle stimulated the acupoint tissue more during lifting-inserting manipulations, while the lined needle and the smooth needle produced less stimulation. The stimulation of the lined needle on the acupoint tissue was the largest during twisting manipulation, whereas the left-hand threaded needle and the right-hand threaded needle had smaller effects. In lifting-inserting and twisting manipulations, both the left-hand threaded needle and right-hand threaded needle provided more stimulation, but the torsion direction in which they produced better stimulation was the opposite.@*CONCLUSION@#According to the simulation results, the ringed pattern enhances stimulation best in the lifting-inserting manipulation, whereas the lined pattern enhances stimulation best in the twisting manipulation. Both the right-hand and left-hand thread patterns have certain enhancing effects in these two operations. Taking the geometric properties of the pattern into account, the left-hand thread pattern and the right-hand thread pattern have the geometric characteristics of both the lined pattern and the ringed pattern. To conclude, a pattern perpendicular to the movement direction during the acupuncture manipulation creates more stimulation. These results have significance for future needle design.

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.

Purpose: The primary objective of this study was to compare the WALANT (wide awake, local anesthesia, no tourniquet) technique with local anesthesia associated with sedation in relation to pain intensity for minor hand surgical procedures. The secondary objective was to evaluate the need for analgesic complementation. Methods: A prospective, randomized, comparative, and clinical study was carried out. The sample size in each group was determined after statistical evaluation of the results of a pilot project. The participants were allocated to one of two groups; those in group 1 were submitted to the WALANT technique, and those in group 2, to local anesthesia associated with sedation, for elective surgery. The surgical procedures were carpal tunnel syndrome, De Quervain's tenosynovitis, synovial cyst, finger cyst, and trigger finger. Pain intensity, need for complementation and evolution to complex regional pain syndrome were evaluated. Results: There was no difference between groups in pain intensity after WALANT and need for intraoperative complementation. There was no significant difference in the amount of opioid applied postoperatively between the groups. There was no difference between groups regarding comfort during surgery. There was no difference in adverse effects and complications between the groups. Hematoma was the most frequent adverse event. No severe adverse events were observed. Conclusions: The WALANT technique promoted an analgesic effect similar to that of local anesthesia associated with sedation, without increasing adverse effects.

Abstract Objective To assess the satisfaction of patients undergoing hand surgery in relation to their hospitalization, their feelings, and the consequences resulting from the surgical procedure as well as to evaluate their opinion and feelings in relation to the surgical procedure and to detect possible weaknesses in the health care of patients undergoing hand surgery. Method Cross-sectional observational clinical study, with a quali-quantitative focus, carried out in an outpatient clinic of a teaching hospital specialized in hand care, with patients of both genders, aged 18 to 75 years, who have undergone corrective surgical procedures of hand pathologies in the last 5 years. Results We obtained a total of 54 participants, 26 females and 28 males, with a minimum age of 18 years and a maximum of 73 years. Patient satisfaction for the 11 moments evaluated had means between 8 and 10, showing great satisfaction. For the other five moments evaluated, the means were between five and eight. We did not get any satisfaction average below fivr. Conclusion The absolute satisfaction of patients undergoing hand surgery is dependent on the humanization of health care, especially in relation to surgical consequences, which require further follow-up. The surgical consequences that require greater follow-up and hinder the routine activities of patients are pain on hand mobilization, limitation of the range of motion, and parathesthesia; thus, proper management of these complaints leads to greater satisfaction.

Resumo Objetivo Determinar a satisfação dos pacientes submetidos a cirurgia de mão em relação a sua internação, seus sentimentos, e as consequências decorrentes do procedimento cirúrgico bem como avaliar sua opinião e seus sentimentos em relação ao procedimento cirúrgico e detectar possíveis fragilidades na atenção à saúde do paciente submetido a cirurgia de mão. Método Estudo clínico observacional de corte transversal, com enfoque quali-quantitativo, realizado em um ambulatório especializado em cuidado da mão de um hospital de ensino, com os pacientes de ambos os gêneros, com idade de 18 a 75 anos, que tenham sido submetidos a procedimentos cirúrgicos corretivos de patologias da mão nos últimos 5 anos. Resultados Obtivemos o total de 54 participantes, sendo 26 do sexo feminino e 28 do sexo masculino, com idade mínima de 18 anos e máxima de 73 anos. Em relação à satisfação dos pacientes em 11 momentos avaliados, as médias foram entre 8 e 10, mostrando grande satisfação. Para os outros cinco momentos avaliados, as médias ficaram entre cinco e oito. Não obtivemos nenhuma média de satisfação abaixo de cinco. Conclusão A satisfação absoluta dos pacientes submetidos à cirurgia de mão é dependente da humanização da assistência à saúde, principalmente em relação às consequências cirúrgicas, que demandam maior acompanhamento. As consequências cirúrgicas que demandam maior acompanhamento e que dificultam as atividades rotineiras dos pacientes são dor à mobilização da mão, limitação do arco de movimento, e parestesia; assim, o manejo adequado dessas queixas leva à maior satisfação.

Abstract Introduction: The practice of digestive endoscopy is a physically demanding activity, with musculoskeletal disorders present in 39 % to 89 % of endoscopists, associated with "excessive use" maneuvers. Due to a lack of knowledge of this problem in endoscopists in Colombia, the main objective is to determine the prevalence, types, and risk factors of musculoskeletal disorders in specialists and graduate students. The secondary objective is to identify the occupational impact, treatments used, and importance of prevention and education in ergonomics. Materials and methods: Analytical cross-sectional observational study. Electronic survey methodology, open from June 1 to 30, 2021. Purposive sampling of 450 endoscopists from four scientific associations and eleven graduate programs, including 50 questions in six groups according to the objectives. We validated 203 responses, with 131 confirmations of musculoskeletal disorders, the group on which the analysis was performed. Results: Global prevalence of musculoskeletal disorders of 64.5 % and prevalence in graduate students of 58.6 %. There was more significant involvement of the upper limbs (right shoulder, left thumb, right elbow), followed by lower back, neck, knees, and hips. Graduate students reported pain in the right hand/fingers (right thumb) and the lower back. There was no significant difference due to work factors, but there was a tendency for more reports when increasing the volume of procedures and years of professional practice. The labor impact showed 78 % absenteeism. The most used treatments were medication, physiotherapy, and rest; 93.8 % had not received ergonomic education. However, there is a positive perception (74.1 % to 90.9 %) of receiving formal training. Discussion: The prevalence reflected the health and safety problem for the endoscopist. Demographic risk factors plus those of the endoscopic practice give rise to an individualized risk framework that enables endoscopists to understand learning and training as a way to prevent musculoskeletal disorders in themselves and their work team.

Resumen Introducción: la práctica de la endoscopia digestiva es una actividad físicamente exigente, con trastornos musculoesqueléticos presentes en el 39 % a 89 %, asociados con maniobras de "uso excesivo". Debido al desconocimiento de este problema en endoscopistas de Colombia, el objetivo principal fue determinar la prevalencia, tipos y factores de riesgo del trastorno musculoesquelético en especialistas y estudiantes de posgrado. El objetivo secundario fue identificar el impacto laboral, los tratamientos utilizados y la importancia atribuida a la prevención y educación en ergonomía. Metodología: estudio observacional de corte transversal analítico. Metodología de encuesta electrónica, abierta del 1 al 30 de junio de 2021. Muestreo intencionado a 450 endoscopistas de 4 asociaciones científicas y 11 programas de posgrado, en el que se incluyeron 50 preguntas en 6 grupos según los objetivos. Se validaron 203 respuestas, con 131 confirmaciones de trastornos musculoesqueléticos, grupo al cual se le realizó el análisis. Resultados: prevalencia global de trastornos musculoesqueléticos de 64,5 % y prevalencia en estudiantes de posgrado de 58,6 %. Hubo mayor afectación de miembros superiores (hombro derecho, pulgar izquierdo, codo derecho); luego, en la espalda baja y cuello; y en las rodillas y caderas. En estudiantes de posgrado se registró dolor en la mano-dedos derechos (pulgar derecho) y en la espalda baja. No hubo diferencia significativa por aspectos laborales, pero hubo tendencia a un mayor reporte al aumentar el volumen de procedimientos y años de práctica profesional. El impacto laboral mostró 78 % de ausentismo laboral. Los tratamientos más empleados fueron medicamentos, fisioterapia y reposo. El 93,8 % no había recibido capacitación ergonómica y hay percepción positiva (74,1 % a 90,9 %) de recibir una didáctica formal. Discusión: la prevalencia evidenció el problema de salud y seguridad para el endoscopista. Los factores de riesgo demográficos más los propios de la práctica endoscópica generan un marco de riesgo individualizado que le permite al endoscopista entender el aprendizaje y la capacitación para prevenir trastornos musculoesqueléticos en sí mismo y su equipo de trabajo.

La posibilidad de operar a los pacientes con afecciones de la mano bajo anestesia local con la lidocaína y la epinefrina usando la técnica WALANT provocó una revolución en la cirugía de la mano, que facilitó la vida de los pacientes y disminuyó los costos de los servicios hospitalarios. Es necesario que los cirujanos conozcan la técnica y la historia de esta técnica. El objetivo fue identificar los orígenes del auge y la caída del mito y del dogma de la prohibición de la adrenalina en los bloqueos anestésicos de los dedos. Se realizó un análisis crítico de los principales textos de los artículos y los libros sobre el uso de la epinefrina en la anestesia de los dedos. La creación del mito de prohibir el uso de la epinefrina en los bloqueos anestésicos de los dedos se produjo debido a la mala interpretación de los informes de los casos de necrosis ocurridos que, en realidad, no fueron causados por la epinefrina. Ese mito influyó en la aparición de un dogma. La historia del uso de la epinefrina en los bloqueos de los dedos anestésicos demuestra que las interpretaciones superficiales y erróneas de las complicaciones clínicas publicadas como informes de casos pueden generar mitos y dogmas. Solo la ciencia puede prevenir y destruir tales mitos y dogmas médicos(AU)

The possibility of operating patients with hand conditions under local anesthesia, with lidocaine and epinephrine, using WALANT technique caused a revolution in hand surgery, which made life easier for patients and lowered the costs of hospital services. Surgeons need to be aware of the possibilities and history of WALANT technique. The objective was to identify the origins of the rise and fall of the myth and dogma of the prohibition of adrenaline in anesthetic finger blocks. A critical analysis of the main texts of the articles and books on the use of epinephrine in finger anesthesia was carried out. The conception of the myth of banning the use of epinephrine in anesthetic finger blocks occurred due to misinterpretation of reports of necrosis occurring, which were not actually caused by epinephrine. That myth influenced the appearance of a dogma. The history of the use of epinephrine in anesthetic finger blocks demonstrates that superficial and misleading interpretations of clinical complications published as case reports can breed myth and dogma. Only science can prevent and destroy such medical myths and dogmas(AU)

Introducción: En los últimos años la anestesia local sin torniquete y con el paciente despierto, técnica conocida por WALANT (por sus siglas en inglés), ha ganado mucha popularidad en las cirugías de la mano y la muñeca. Objetivo: Reportar nuestra experiencia con el uso de la técnica WALANT, a fin de prescindir del uso del torniquete en las cirugías de la mano. Métodos: En noviembre del 2020 fueron intervenidos 30 pacientes por diversas enfermedades ortopédicas, entre las que figuraron: dedos en resorte, síndrome del túnel carpiano, tenovaginitis estenosante del pulgar, gangliones del carpo y amputación del tercer radio por rigidez en extensión postraumática, entre otras. Para la evaluación de la técnica tuvimos en cuenta: tiempo quirúrgico, magnitud del sangrado, dolor durante la infiltración anestésica, la intervención, y en las primeras 24 horas del postoperatorio, la necesidad de refuerzo anestésico, uso de isquemia, complicaciones y nivel de satisfacción del paciente. Resultados: Los resultados obtenidos con esta técnica anestésica son semejantes a otras, con las ventajas que el sangrado es leve, no hay que utilizar isquemia, el tiempo quirúrgico es menor y el efecto anestésico duró entre 10 y 12 horas en todos los pacientes. En ninguno de los pacientes hubo necesidad de refuerzo anestésico. Conclusiones: Se demuestra la efectividad de la técnica WALANT en las cirugías de mano. Con ella se disminuye el gasto de materiales para el acto quirúrgico, así como de personal, es de fácil aplicación y disminuyen las sensaciones desagradables y los peligros del uso de isquemia en los pacientes(AU)

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)

Resumen El presente caso es un ejemplo del síndrome de la mano inútil de Oppenheim secundario a un astrocitoma cervical alto. La pérdida sensorial propioceptiva y discriminativa suspendida con conservación de la termoalgesia y el tacto crudo en ambas extremidades superiores es secundaria al daño a la entrada de la raíz dorsal y al núcleo cuneiforme. La torpeza y las dificultades para una prensión precisa con la mano se deben al daño del núcleo proprioespinal en las astas dorsales a nivel C3-C4. Este núcleo integra influencias excitadoras descendentes del tracto corticoespinal e interneuronas inhibitorias controladas por los sistemas descendentes y las aferencias de las extremidades anteriores. Probablemente la pérdida de las aferentes cervicales propioceptivas inhibitorias sea la culpable de las dificultades para agarrar con las manos.

The present case is an example of the useless hand syndrome of Oppenheim secondary to a high cervical astrocytoma. The suspended proprioceptive and discriminative sensory loss with conservation of thermoalgesia and crude touch in both upper extremities is secondary to damage to dorsal root entry and cuneate nucleus. The clumsiness and difficulties in precise grasping with the hand are due to damage of the propriospinal nucleus in the dorsal horns at C3-C4 level. This nucleus integrates descending excitatory influences from corticospinal tract and inhibitory interneurons controlled by descending systems and the forelimb afferents. Probably the loss of the inhibitory proprioceptive cervical afferents is the culprit of the difficulties in grasping by the hands.

SUMMARY: The current report presented a rare variant of extensor indicis brevis muscle, replacing extensor indicis, in the left hand of an adult male cadaver. The origin of the muscle was reported, for the first time, to be from the distal margins of radius and ulna. The muscle is inserted into the extensor expansion of the index. A new classification for extensor indicis brevis muscle was proposed based on its origin. Awareness of rare anatomical variations would help clinicians and surgeons in accurately managing suspected cases and planning surgical procedures.

RESUMEN: Este informe presenta una variante rara del músculo extensor corto del índice, que reemplaza al extensor del índice en la mano izquierda de un cadáver masculino adulto. Se informó por primera vez, que el origen del músculo se realiza en la parte distal de los márgenes del radio y la ulna. El músculo se insertaba en la expansión extensora del índice. Se propuso una nueva clasificación para el músculo extensor corto del índice basada en su origen. El conocimiento de las variaciones anatómicas raras es útil para los médicos y cirujanos al abordar los casos sospechosos y planificar los procedimientos quirúrgicos.

SUMMARY: The purpose of this research is to determine a regression equation for estimation of stature from hand length measurements. This research was carried out on 1001 subjects (504 male and 497 female) among the population of Montenegrin adolescents. The stature and hand length measurements were taken according to the ISAK protocol, and the data were analyzed statistically; the relationships between stature and hand length measurements were derived using simple correlation. A comparison of the means of hand length measurements between sex was performed using a t-test, while a linear regression analysis was employed to examine the extent to which hand length t measurements can reliably predict stature. The results of this research study confirmed that hand length reliably predicts stature in both sexes of Montenegrin adolescents and revealed a very useful finding for physical anthropologists and experts from related fields.

Intelligent and precision medical treatment is the future development trend of surgical operations. We proposed a core architecture of orthopedic robots with human-like thinking based on the growing demand for orthopedic robots and disadvantages of current robots, it consists of brain, eyes and hands three modules according to functions. The architecture design is extremely in line with the doctor's logic so that the work process of the orthopedic robot is similar to the process of traditional surgery which is mainly done by the doctor's brain-eye-hand coordination. It realizes the digitization of the doctor's thinking, the immediacy and visualization of surgical information and the accuracy of surgical operation process. The clinical application proved that the orthopedic robot has the advantages of higher accuracy, less radiation and shorter operation time, which can be further promoted clinically.

An auxiliary dining robot is designed in this paper, which implements the humanoid feeding function with theory of inventive problem solving (TRIZ) theory and aims at the demand of special auxiliary nursing equipment. Firstly, this robot simulated the motion function of human arm by using the tandem joints of the manipulator. The end-effector used a motor-driven spoon to simulate the feeding actions of human hand. Meanwhile, the eye in hand installation style was adopted to instead the human vision to realize its automatic feeding action. Moreover, the feeding and drinking actions of the dining robot were considered comprehensively with the flexibility of spatial movement under the lowest degree of freedom (DOF) configuration. The structure of the dining robot was confirmed by analyzing its stresses and discussing the specific application scenarios under this condition. Finally, the simulation results demonstrate high-flexibility of the dining robot in the workspace with lowest DOF configuration.

Introducción: Las fracturas aisladas del hueso grande son muy infrecuentes en los niños y se producen por traumatismos de alta energía. Pueden pasar desapercibidas en la valoración inicial y las radiografías solo permiten identificar las lesiones en huesos osificados, por lo que son necesarias pruebas complementarias, como la resonancia magnética, para descartar posibles lesiones del carpo asociadas, sobre todo en menores de 10 años. Se presenta el caso de una fractura aislada del hueso grande con aparición de quiste sinovial por causa traumática en un paciente pediátrico, tratado mediante inmovilización con yeso antebraquial durante cuatro semanas, con buena evolución. Conclusión: El manejo de estos casos depende de la gravedad de la lesión y, aunque por lo común evolucionan bien con un tratamiento conservador, su diagnóstico precoz permite elegir la mejor opción y evitar posibles complicaciones, como la falta de consolidación o la necrosis avascular. Nivel de Evidencia: IV

Introduction: Isolated capitate fractures, caused by high-energy trauma, are rare in children. They can be missed at the initial assessment of the patient and radiographs only allow the identification of lesions in ossified bones, so complementary tests such as magnetic resonance imaging are necessary to rule out possible associated carpal lesions, especially in children under 10 years old. We present the case of an isolated capitate bone fracture with the appearance of a synovial cyst due to trauma in a pediatric patient, treated by immobilization with a short arm cast for four weeks, with good evolution. Conclusion: The management of these cases depends on the severity of the injury. In most cases conservative treatment is enough but early diagnosis allows us to choose the best option and avoid possible complications as nonunion or avascular necrosis. Level of Evidence: IV
