[Tele-rehabilitation in musculoskeletal pathology of the upper and lower limb]. / Telerrehabilitación en patología musculoesquelética de miembro superior e inferior.

Chronic musculoskeletal conditions cause pain and disability and have significant impact on morbidity worldwide. Tele-rehabilitation is proposed as an alternative or complement to improve patient's muscle function, pain, and quality of life. However, the satisfaction of both patients and professionals must be assessed, together with the patient's daily life activity independence. A search of the literature was made to locate assessment reports, systematic reviews and reports from regulatory bodies with support from a documentarian from the Andalusian Health Technologies Assessment Area (AETSA). For this purpose, the following sources were used: Medline, EMBASE, INAHTA (international network of health technologies assessment) and PEDro (Physiotherapy Evidence Database) from 2014 onwards. Subsequently a secondary search was carried out on the articles selected in the initial search. A search of open clinical trials was also carried out in the database: www.ClinicalTrials.gov Initially 345 articles were identified. Duplicated articles (57) were excluded. By first analysing the title and abstract 238 articles were excluded. The full texts of the remaining 30 articles were analysed. Finally 18 articles were included.

Concurrent uper limb and hip fracture in the elderly: experience at our centre. / Fracturas concomitantes de miembro superior y cadera en pacientes mayores de 65 años: experiencia en nuestro centro.

INTRODUCTION: The incidence of hip fracture in the elderly is on the rise, occasionally accompanied by concurrent upper limb fractures. Our investigation aims to determine whether these patients experience poorer functional outcomes, prolonged hospitalization, or higher mortality rates when compared to those with isolated hip fracture. MATERIAL AND METHODS: We retrospectively reviewed 1,088 elderly patients admitted to our centre with hip fracture between January 2017 and March 2020. We recorded the presence of concomitant fractures and their treatment. We analyzed the duration of hospital stay, in-hospital mortality and function. RESULTS: We identified 63 patients with concomitant upper limb fracture (5.6%). Among them, 93.7% were women, and the average age was 86.4 years. 80.9% of the upper limb fractures were distal radius or proximal humerus. Patients with concomitant fracture had increased length of stay (mean, 19.6 vs, 12.8, p=0.002), decreased proportion of patients returning to their own home at discharge (23.6% vs, 26.3%, p=0.042) and increased in-hospital mortality rate (9.5% vs, 5.9%, p=0.003). CONCLUSIONS: Patients with concomitant upper limb fracture require a longer length of stay and exhibit an elevated in-hospital mortality rate. Furthermore, this condition is associated with a reduced short-term functional recovery, thereby decreasing the chances of the patient returning home upon hospital discharge.

[Validity and reliability of DASH questionnaire in women who suffer from lymphedema as a side effect of a breast cancer treatment]. / Validez y fiabilidad del cuestionario DASH en mujeres con linfedema secundario a tratamiento de cáncer de mama.

INTRODUCTION: DASH questionnaire was designed to assess upper limb function in musculoskeletal pathologies. The aim of this manuscript is to study the reliability and validity of this questionnaire, to determine if is adequate to use in women with lymphedema due to breast cancer treatment. METHODS: Prospective study in 65 women with lymphedema due to breast cancer treatment was done, in which the reliability of DASH score with internal consistency (Cronbach's alpha) and test-retest reproducibility 15 days' interval (interclass correlation coefficient) and validity by correlation with SF-36v2 and FACT-B+4 (r or Kendall's τ b) scores was investigated. RESULTS: The internal consistency and the test-retest were Cronbach's alpha 0.969 and interclass correlation coefficient 0.861, respectively. There was correlation between the DASH score with the SF-36v2 score, mainly in the areas of physical function, body pain and physical role (r 0.800, 0.738, and 0.682, respectively; p<0.001), and lowest with the emotional and social wellbeing. The DASH score had correlation with FACT-B+4 (0.836; p<0.001) and the subscales the upper limb score (r=0.816; p<0.001), and there was no correlation with the social/familiar subscale (r=0.193; p=0.216). CONCLUSION: The DASH questionnaire is a reliable and valid tool to assess upper limb functionality in Spanish women with breast cancer related lymphedema.

Therapeutic intervention with virtual reality in patients with Parkinson's disease for upper limb motor training: A systematic review.

To analyze the scientific evidence regarding changes in upper extremities in patients with Parkinson's disease who use virtual reality as part of their neurological rehabilitation treatment. The search was carried out in the following databases: MEDLINE, Cochrane Library, PEDROs and SCOPUS. The following inclusion criteria were applied to a total of 106 articles: Randomized clinical trials with an age of 5 years, the sample had to be of patients with PD (regardless of their state of involvement) and who had performed RV in the treatment of limbs superiors. A total of n=7 articles were used, in which the variables corresponding to upper limb motor control were measured, such as: fine motor dexterity, gross motor dexterity, strength, tremor, functionality and speed. Virtual Reality as tool in neurorehabilitation in patients with Parkinson's disease shows positive effects in all measurements related to upper limb motor control.

[Update on prosthesis for partial hand and finger amputations]. / Actualización en prótesis para amputaciones parciales de mano y dedos.

Partial hand and finger amputations are relatively rare but devastating due to the consequences they provoque. In addition, they are more likely than lower limb amputations in car accidents, work accidents and by certain weapons of war. Men are going to have a much higher risk of traumatic amputation than women, with a rate 6.6 times higher. Fitting can be a complex process and a challenge for professionals. For this reason, it is important to know all the options available on the market that can meet the needs of patients, from cosmetic to myoelectric prostheses. Fitting requires the coordinated activity of a multiassistant clinical work team, the center of the team being the person who has suffered the amputation, who must have all the information possible to be able to actively participate in decision-making.

[Effectiveness of constraint-induced movement therapy in upper extremity rehabilitation in patients with cerebral palsy: A systematic review]. / Efectividad de la terapia de movimiento inducido por restricción del lado sano en la rehabilitación del miembro superior en pacientes con parálisis cerebral: revisión sistemática.

BACKGROUND AND OBJECTIVE: In hemiplegic cerebral palsy, learned non-use may appear. This phenomenon can be reversed by constraint-induced movement therapy in the healthy side. The aim of this article was to review the evidence of the effectiveness of this therapy on upper extremity functioning, the performance of activities of daily living and quality of life. PATIENTS AND METHODS: We performed a systematic review between January and April 2019 in the PubMed, COCHRANE, PEDro and TRIPDATABASE databases. We included 14 clinical studies describing their characteristics. RESULTS: Most of the studies found significant improvements compared with control groups. Only one article investigated quality of life. CONCLUSIONS: Constraint-induced movement therapy seems to have positive effects in the motor rehabilitation of the upper extremity in patients with hemiplegic cerebral palsy. Further studies are needed to assess the individual factors of greatest influence in rehabilitation.

Upper limb nerve variations may alter clinical diagnosis: a scoping review / Las variaciones nerviosas del miembros superior pueden alterar el diagnóstico clínico: una revisión de alcance

SUMMARY: Upper limb nerve variations may be related to the absence of a nerve, an interconnection between two nerves or a variant course. The purpose of this review is to screen the existing literature on upper limb nerve variations that may alter the neurologic diagnostic process. A scoping review was performed following PRISMA for Scoping Reviews guidelines. Initially, 1331 articles were identified by searching Pubmed and Web of Science until the 22nd of October 2022. After screening, reading, and additional searching 50 articles were included in this review. Variations were divided into two categories: 1) variations causing a different innervation pattern involving sensory, motor, or both types of fibers, and 2) variations causing or related to compression syndromes. Two-thirds of the included articles were cadaver studies. Nine articles were diagnostic studies on symptomatic or healthy individuals involving medical imaging and/or surgery. Nerve variations that may cause a different innervation pattern concern most frequently their interconnection. The connection between the median and musculocutaneous nerve in the upper limb and the connection between the median and ulnar nerve in the forearm (Martin-Gruber) or hand (Riche-Cannieu) may be present in half of the population. Injury to these connections may cause compound peripheral neuropathies a result of variant sensory and motor branching patterns. Muscular, vascular, or combined anomalies in the forearm were reported as causes of entrapment neuropathies. These nerve variations may mimic classical entrapment syndromes such as carpal tunnel syndrome or compression at ulnar canal (Guyon's canal). Knowledge of frequent nerve variations in the arm may be important during the diagnostic process and examination. Variant innervation patterns may explain non-classical clinical signs and/or symptoms during provocative tests. Classical nerve compression syndromes in the arm may warrant for differential diagnosis, especially in the case of persistent or recurrent symptoms.

Las variaciones nerviosas del miembro superior pueden estar relacionadas con la ausencia de un nervio, una interconexión entre dos nervios o un curso variante. El objetivo de esta revisión fue examinar la literatura existente sobre las variaciones de los nervios de los miembros superiores que pueden alterar el proceso de diagnóstico neurológico. Se realizó una revisión de alcance siguiendo las pautas de PRISMA para revisiones de alcance. Inicialmente, se identificaron 1331 artículos mediante la búsqueda en Pubmed y Web of Science hasta el 22 de octubre de 2022. Después de la selección, la lectura y la búsqueda adicional, se incluyeron 50 artículos en esta revisión. Las variaciones se dividieron en dos categorías: 1) variaciones que causan un patrón de inervación diferente que involucra fibras sensoriales, motoras o de ambos tipos, y 2) variaciones que causan o están relacionadas con síndromes de compresión. Dos tercios de los artículos incluidos eran estudios de cadáveres. Nueve artículos fueron estudios de diagnóstico en individuos sintomáticos o sanos que involucraron imágenes médicas y/o cirugía. Las variaciones nerviosas que pueden causar un patrón de inervación diferente se refieren con mayor frecuencia a su interconexión. La conexión entre el nervio mediano y musculocutáneo en el miembro superior y la conexión entre el nervio mediano y ulnar en el antebrazo (Martin-Gruber) o la mano (Riche-Cannieu) puede estar presente en la mitad de la población. La lesión de estas conexiones puede causar neuropatías periféricas compuestas como resultado de patrones de ramificación variantes sensitivos y motores. Se informaron anomalías musculares, vasculares o combinadas en el antebrazo como causas de neuropatías por atrapamiento. Estas variaciones nerviosas pueden imitar los síndromes de atrapamiento clásicos, como el síndrome del túnel carpiano o la compresión en el canal ulnar. El conocimiento de las variaciones nerviosas frecuentes en el brazo puede ser importante durante el proceso de diagnóstico y examen. Los patrones de inervación variantes pueden explicar los signos y/o síntomas clínicos no clásicos durante las pruebas de provocación. Los síndromes clásicos de compresión nerviosa en el brazo pueden justificar el diagnóstico diferencial, especialmente en el caso de síntomas persistentes o recurrentes.

Clinical assessment of patients with isolated hip fractures associated with an upper limb fracture. / Evaluación clínica de pacientes con fractura de cadera aislada y asociada a fractura de miembro superior.

INTRODUCTION: Some patients with a hip fracture also present a concomitant upper limb fracture. We want to know whether these patients have a worse functional level and whether they have any differences in various clinical parameters compared with patients with an isolated hip fracture. MATERIAL AND METHODS: We retrospectively reviewed 1061 discharge reports from the Orthogeriatrics Unit. We collected information on several clinical parameters of the fractures. Subsequently, we performed a statistical analysis of the data by comparing the associated fracture group with the isolated fracture group. RESULTS: We detected 44 patients with associated upper limb fracture, 90.9% were women (40) and the average age was 84.45years. Eighty-one point eight percent of the upper limb fractures were distal radius or proximal humerus. Pertrochanteric fractures were the most common (none of them were subtrochanteric fractures). Surgical delay was 2.60days and the average hospital stay was 12.30days. Sixty-four point three percent were nail surgery and 31% arthroplasty. The mean Barthel index score was 84.88 (P=.021). Fifty-two point 5 percent of the patients in the study group were referred to a functional support unit (P=.03). The in-hospital mortality rate was 4.2%, with no differences between groups. CONCLUSIONS: Patients with an associated fracture have a higher previous functional capacity and they are more independent. Nevertheless, after the fracture they need more help from the healthcare system for optimal functional recovery.

Validation of the FACT-B+4-UL questionnaire and exploration of its predictive value in women submitted to surgery for breast cancer. / Validación del cuestionario FACT-B+4-MS y exploración de su capacidad predictora en mujeres intervenidas de cáncer de mama.

INTRODUCTION AND OBJETIVE: The early detection of upper limb complications is important in women operated on for breast cancer. The "FACT-B+4-UL" questionnaire, a specific variant of the Functional Assessment of Cancer Therapy-Breast (FACT-B) is available among others to measure the upper limb function. PATIENTS AND METHODS: The Spanish version of the upper limb subscale of the FACT-B+4 was validated in a prospective cohort of 201 women operated on for breast cancer (factor analysis, internal consistency, test-retest reliability, construct validity and sensitivity to change were determined). Its predictive capacity of subsequent lymphoedema and other complications in the upper limb was explored using logistic regression. RESULTS: This subscale is unifactorial and has a great internal consistency (Cronbach's alpha: 0.87), its test-retest reliability and construct validity are strong (intraclass correlation coefficient: 0.986; Pearson's R with "Quick DASH": 0.81) as is its sensitivity to change. It didn't predict the onset of lymphedema. Its predictive capacity for other upper limb complications is low. CONCLUSIONS: FACT-B+4-UL is useful in measuring upper limb disability in women surgically treated for breast cancer; but it does not predict the onset of lymphoedema and its predictive capacity for others complications in the upper limb is low.

Pseudoaneurisma humeral secundario a punción arterial inadvertida / Brachial artery pseudoaneurysm secondary to inadvertent arterial puncture

RESUMEN Los pseudoaneurismas de la arteria humeral son infrecuentes, pero pueden asociarse a complicaciones de alta morbilidad como la isquemia de miembro superior. Comunicamos un caso de pseudoaneurisma humeral en el pliegue del codo, que se presentó como tumor pulsátil con leve disminución de la temperatura y parestesias en la mano homolateral de un año de evolución, debido a una punción arterial inadvertida durante la venopunción para extracción de sangre. Se trató con éxito mediante resección quirúrgica más reconstrucción vascular con bypass húmero-cubital y bypass húmero-radial ambos con vena safena. Se discuten las diversas opciones terapéuticas disponibles para los pseudoaneurismas humerales considerando las características anatómicas y la sintomatología del paciente.

ABSTRACT Brachial artery pseudoaneurysms are rare but can be associated with severe complications as ischemia of the upper extremity. We report a case of a brachial artery pseudoaneurysm in the crease of the elbow presenting as a pulsating mass with progressive growth over the past year. The ipsilateral hand was sightly cold and presented paresthesia. The lesion was due to inadvertent arterial puncture during venipuncture. The pseudoaneurysm was successfully treated with surgical resection and vascular reconstruction with a brachial to ulnar artery bypass and brachial to radial artery bypass with saphenous vein graft. The different therapeutic options available for brachial artery pseudoaneurysms are discussed, considering the anatomic characteristics and patients' symptoms.

Aneurisma venoso postraumático en extremidades superiores. Presentación de dos casos / Post-traumatic venous aneurysm in the upper limbs. Case report on two patients / Aneurisma venoso pós-traumático nos membros superiores. Apresentação de dois casos

RESUMEN Los aneurismas venosos, en especial de la extremidad superior, son malformaciones vasculares de baja frecuencia. Se presentó el manejo de dos pacientes del sexo femenino atendidas en el Servicio de Angiología y Cirugía Vascular del Hospital General Docente "Dr. Agostinho Neto" de la provincia Guantánamo, Cuba, a las que se les diagnosticaron aneurismas en diferentes segmentos del sistema venoso superficial de la extremidad superior, los que se resecaron quirúrgicamente y se les confirmó el diagnóstico mediante biopsia.

ABSTRACT Venous aneurysms, especially the ones located in the upper limbs, are vascular malformations with low incidence in the population. Two cases of venous aneurisms on female patients showed up at the Angiology and Vascular Surgery services at the General Teaching Hospital ¨Dr. Agostinho Neto¨ in Guantanamo, Cuba. Aneurism diagnosis was confirmed through biopsy. They were located in different segments of the superficial venous system of the upper limbs, and were surgically resected.

RESUMO Os aneurismas venosos, principalmente de membro superior, são malformações vasculares de baixa frequência. Foi apresentada a gestão de duas pacientes do sexo feminino atendidas no Serviço de Angiologia e Cirurgia Vascular do Hospital General Docente "Dr. Agostinho Neto" da província de Guantánamo, Cuba, que foram diagnosticados com aneurismas em diferentes segmentos do sistema venoso superficial do membro superior, os quais foram ressecados cirurgicamente e o diagnóstico foi confirmado por biópsia.

Traduccion, adaptacion cultural y validacion de una escala de funcion del miembro superior: DASH / Translation, cultural adaptation and validation of the DASH - upper extremity functional scale

Introducción El objetivo del estudio fue realizar la traducción, adaptación cultural y validación de una escala de función del miembro superior, denominada DASH, por sus siglas en inglés (discapacidad del brazo, el hombro y la mano). Materiales y métodos Se realizó un estudio metodológico de validación de escalas: traducción (constó de traducciones inglés-español, comité de expertos inicial, dos contratraducciones, un segundo comité de expertos y una traducción definitiva); evaluación de confiabilidad (pruebas de coherencia interna, test-retest y cambio mínimo detectable); respuesta al cambio (mediciones en pacientes antes y después de tratamiento), y estudio de validez (se hicieron pruebas de validez de apariencia, de constructo y de criterio). Resultados La prueba traducida fue aplicada a 338 pacientes con enfermedades de mano y hombro, 311 fueron utilizables. La consistencia interna, mediante alfa de Cronbach, se estimó > 0,96; el resultado del coeficiente de concordancia de Lin fue 0,86. El cambio mínimo detectable fue 15,88, la capacidad de respuesta al cambio mediante la prueba de la t de Student aplicada sobre la diferencia en la puntuación arrojó una p < 0,001; adicionalmente se corrió una correlación no paramétrica de Spearman entre la diferencia en la puntuación DASH y la diferencia en la escala visual analógica de cambio en estado de salud (EVA SALUD) y se obtuvo un r = 0,62 (p < 0,001). Discusión La escala DASH traducida y adaptada al español demostró una buena fiabilidad, estabilidad y capacidad de respuesta al cambio, logró discriminar entre diferentes enfermedades y tiene una validez estimada buena en cuanto a contenido, constructo y criterio.

Introduction The objective of the study was to perform translation, cultural adaptation and validation of a function scale of the upper limb, called DASH, for its acronyms in English (disability of the arm, shoulder and hand). Materials and methods A methodological study of scale validation was performed: translation (consisting of English-Spanish translations, initial expert committee, two backtranslations, a second committee of experts and a definitive translation); reliability assessment (internal consistency tests, test-retest and minimum detectable change); response to change (measurements in patients before and after treatment), and validity study (validity tests of appearance, construct and criteria were performed). Results The translated test was applied to 338 patients with hand and shoulder diseases, 311 were usable. The internal consistency, using Cronbach's alpha, was estimated to be > 0.96; The result of the Lin coefficient of agreement was 0.86. The minimum detectable change was 15.88, the ability to respond to change using the Student t test applied on the difference in score yielded a p <0.001; A nonparametric Spearman correlation was recorded between the difference in the DASH score and the difference in the visual analogue scale of change in health status (EVA HEALTH) with r = 0.62 (p <0.001). Discussion The DASH scale, translated and adapted to Spanish demonstrated good reliability, stability and responsiveness to change, managed to discriminate between different diseases and has an estimated validity in terms of content, construct and criteria.

An unusual case of primate arterial pattern in a human upper limb / Un caso inusual de patrón arterial de primates en un miembro superior humano

During routine undergraduate dissections of the upper limb, variations on the usual arterial and muscular patterns were observed in a 68 year-old male cadaver. The arterial and muscular pattern found in our specimen is similar to that of some primates in the following terms. 1) Brachial artery duplicity, on the right side, with a superficial brachio-ulnoradial artery. 2) In the right upper limb, the biceps brachii muscle continued with the superficial muscles of the forearm. 3) The brachial artery on the left side, cross over in front of the median nerve, as the only artery of the arm with a network axillary pattern. 4) On both sides, the ulnar artery was superficial and originated at the elbow from superficial brachial arteries. 5) The right anterior interosseous artery intervened in the vascularization of the hand. These results suggest that this may be a case of early detention of human embryonic development and/or the persistence of phylogenetic older patterns. In the literature, we have found no reference to the presence of all these variations in the same individual. The objective of our study was to analyze these variations from an embryological and phylogenetic perspective.

Durante las disecciones de pregrado de rutina del miembro superior, se observaron variaciones en los patrones arteriales y musculares habituales en un cadáver macho de 68 años. El patrón arterial y muscular que se encuentra en nuestro espécimen es similar al de algunos primates en los siguientes términos. 1) Duplicidad de la arteria braquial, en el lado derecho, con una arteria braquioulnoradial superficial. 2) En el miembro superior derecho, el músculo bíceps braquial continuó con los músculos superficiales del antebrazo. 3) La arteria braquial en el lado izquierdo, se cruza frente al nervio mediano, como la única arteria del brazo con un patrón axilar en red. 4) En ambos lados, la arteria ulnar era superficial y se originó en el codo de las arterias braquiales superficiales. 5) La arteria interósea anterior derecha intervino en la vascularización de la mano. Estos resultados sugieren que este puede ser un caso de detención temprana del desarrollo embrionario humano y/o la persistencia de patrones filogenéticos más antiguos. En la literatura, no hemos encontrado ninguna referencia a la presencia de todas estas variaciones en el mismo individuo. El objetivo de nuestro estudio fue analizar estas variaciones desde una perspectiva embriológica y filogenética.

Differences in body composition of upper and lower limbs in elite taekwondo athletes / Diferencias en la composición corporal de los miembros superiores e Inferiores en atletas de taekwondo de élite

In this study, we analyzed the differences in body composition among athletes during different stages of their career Forty taekwondo athletes and 10 non-athletes (20 males and 30 females) with a mean age of 18.2 years (range, 15-23 years), a mean height of 173.4 cm, and a mean body weight of 64.8 kg were studied using dual energy X-ray absorptiometry and Biodex balance system. The bone mineral density of upper and lower limbs was higher among university athletes of both sexes than in high school athletes. The lean body mass of male athletes in the university was higher than in high school male athletes. By contrast, in case of females, the opposite results were obtained for the upper and lower limbs. Elucidation of the body composition according to career and sex of taekwondo athlete is worthwhile.

En este estudio, analizamos las diferencias de la composición corporal entre los atletas durante las diferentes etapas de su carrera. Se estudiaron cuarenta atletas de taekwondo y 10 no atletas (20 hombres y 30 mujeres) edad media de 18,2 años (rango, 15-23 años), una altura media de 173,4 cm y un peso corporal medio de 64,8 kg. Se utilizaron la absorciometría de rayos X de energía dual y el sistema de equilibrio Biodex. La densidad mineral ósea de las miembros superiores e inferiores fue mayor entre los atletas universitarios de ambos sexos, que en los atletas de educación secundaria. La masa corporal magra de los atletas varones en la universidad fue mayor que en los varones de la educación secundaria. Por el contrario, en el caso de las mujeres, se obtuvieron los resultados opuestos para las miembros superiores e inferiores. En conclusión se debe considerar un análisis de la composición corporal según la carrera y el sexo del atleta de taekwondo.

Characterization of workers covered by a risk insurance company inColombia who suffered amputation / Caracterización de trabajadores amputados atendidos en una aseguradora de riesgos laborales en Colombia

| Background: Scarcity of information on the sociodemographic, occupational and clinical characteristics of workers who suffer upper limb amputation hinders planning and implementing actions to improve their living and working conditions. Objective: To investigate the sociodemographic, occupational and clinical characteristics of workers covered by a risk insurance company in Colombia who suffered upper limb amputations and investigate their association with risk categories. Methods: Exploratory, descriptive, retrospective and analytical study of data relative to workers covered by a risk insurance company in Colombia who suffered upper limb amputation in the period from 1982 and 2017. Following approval by School of Medicine, CES University, and a risk insurance company, we developed a checklist to collect data on the variables of interest. We performed descriptive and bivariate analysis with 95% of confidence and error of 5%. Results: The largest proportion of workers who suffered amputation were men aged 36 to 55 years old and residing in the Andean region of Colombia. Amputations mainly followed incidents during the performance of tasks, particularly in jobs in the secondary economic sector and classified as with type 3 risk. Conclusion: We were able to identify some characteristics associated with accidents, including age, risk class, economic sector, care received and disability duration. The results point to the need for appropriate interventions for the benefit of workers and risk insurance companies

| Introducción: La escasa información sobre las características sociodemográficas, laborales y clínicas de trabajadores que sufren amputaciones de miembro superior dificultan planear y adelantar acciones que aporten al mejoramiento de sus condiciones de vida y de salud. Objetivos: Determinar las características sociodemográficas, laborales y clínicas de trabajadores con amputaciones en miembros superiores atendidos en una aseguradora de riesgos laborales colombiana, para establecer una asociación con el tipo de riesgo. Métodos: Estudio exploratorio, descriptivo y retrospectivo con intención analítica. Se tomaron registros de la base de datos de pacientes con amputaciones de miembro superior atendidos en una aseguradora colombiana entre los años 1982 y 2017. Se aplicó una lista de chequeo, previa aprobación del proyecto por parte de la Facultad de Medicina de la Universidad CES y una aseguradora de riesgos laborales colombiana, para identificar las variables en estudio. Se realizaron análisis descriptivos y bivariados utilizando pruebas estadísticas con una confianza del 95% y un error del 5%. Resultados: Se observó que una mayor proporción de los trabajadores amputados fueron hombres entre 36 y 55 años de edad, residentes y trabajadores en la región andina. Las amputaciones fueron derivadas fundamentalmente de accidentes propios de su labor, particularmente para aquellos del sector secundario, clasificados como riesgo tipo 3. Conclusión: Se observaron algunas características asociadas a la accidentalidad laboral como edad, clasificación de riesgo, sector económico, tipo de atención hospitalaria requerida y días de incapacidad, evidenciando la importancia de intervenir adecuadamente para el beneficio de los pacientes y la aseguradora de riesgos laborales.

Tratamiento quirúrgico del linfedema de miembro superior postratamiento del cáncer de mama / Surgical treatment of lymphedema of the upper limb after breast cancer

Introducción. El linfedema de miembro superior postratamiento del cáncer de mama es una afección progresiva y crónica que compromete a una gran cantidad de pacientes causando efectos físicos, psicológicos y sociales. El linfedema secundario se da en un 20-40% de los casos luego de la cirugía del cáncer de mama con vaciamiento y radioterapia. Este es un problema desafiante. El tratamiento conservador ha demostrado no ser suficientemente exitoso por lo que su tratamiento quirúrgico es una buena opción. La transferencia microquirúrgica de nódulo linfático vascularizado (TNLV) brindó una nueva esperanza para este grupo de pacientes. Material y métodos. En el periodo comprendido entre marzo 2016 y agosto 2018 se analizaron 16 pacientes con una edad promedio de 50,25. Se realizó tratamiento quirúrgico basándose en la transferencia de nódulo linfático vascularizado (TNLV) de la ingle a la axila por medio de una anastomosis microquirúrgica de la arteria circunfleja ilíaca superficial en pacientes que presentaron linfedema secundario al tratamiento del cáncer de mama. Se realizó simultáneamente a la cirugía reconstructiva de la mama con colgajo libre DIEP y también en un segundo tiempo quirúrgico. Tiempo quirúrgico de 4,3 horas y una estadía en internación de 2,3 días. Resultados. La vitalidad de los colgajos fue 100%. Como morbilidad, se presentaron cuatro casos de seroma, una infección y una dehiscencia en la zona dadora. Con un seguimiento promedio de 10,43 meses y una reducción significativa de volumen del miembro afectado del 27.47% en comparación con el preoperatorio. La incidencia de celulitis descendió. La linfografía posoperatoria indicó una mejoría en el drenaje linfático del miembro afectado. Conclusiones. La transferencia linfática vascularizada al miembro afectado en conjunto con la cirugía reconstructiva mamaria DIEP es un procedimiento seguro y eficaz en el tratamiento del linfedema de miembro superior en pacientes mastectomizadas con vaciamiento ganglionar y radioterapia.

Purpose: Upper limb lymphedema post breast cancer treatment is a progressive and chronic condition that involves a large number of patients causing psychological, physical and social effects. The incidence of secondary lymphedema is about 20-40% before breast cancer treatment. This is a challenging problem. The conservative treatment has shown not to be successful enough so the surgery is a really good option. The vascularized lymph node transfer (VLNT) offers some hope to this group of patients. The purpose of the investigation is to demonstrate that te VLNT is an efficacious approach to treating postmastectomy upper limb lymphedema. Methods: From March 2016 to August 2018 were analyzed sixteen patients with a mean age of 50.25 years. They all have secondary lymphedema. They underwent surgical treatment based on vascularized lymph node transfer from the groin to the axially area or elbow as a recipent site. The deep inferior epigastric perforator flap was made at the same time, as a stacked flap. In only six cases, the VLNT was made on a second surgical time. The serrato's vessels were used as a recipient vessels in the axilary area and a radial artery branch and the cephalic vein were used in the elbow. Results: The flaps vitality was 100%. There were four seroma cases, one infection and one dehiscence. At a mean follow up of 10.43, the mean circumference reduction rate of the lymphedematous limb was about 27.47% between the preoperative and the postoperative groups. The postoperative lymphoscintigrapy showed a little improvement. The follow up of the vitality of the nodes was made by a lymphatic contrast tomography, and it showed all nodes survived. Conclusions: The vascularized lymph node transfer and the DIEP flap were confirmed as an effective and safe treatment to the secondary lymphedema in this type of patients, and it really improves postmastectomy upper limb lymphedema

Implementación de un modelo de atención kinesiológico, temprano y prospectivo, en personas con cáncer de mama / Implementation of an early and prospective physical therapy model care in people with breast cancer

Resumen El cáncer de mama es un problema de salud pública en Chile y el mundo por su alta incidencia. La cirugía es un pilar fundamental en el tratamiento del cáncer de mama. Hasta un 60% de las personas tratadas por cáncer de mama presentan alteraciones funcionales en el miembro superior. Existen modelos sanitarios para la rehabilitación de las alteraciones funcionales, sin embargo, en Chile no es un estándar en la atención de salud. Este artículo describe: 1) las alteraciones del miembro superior secundarias a la cirugía por cáncer de mama y 2) un modelo de atención kinesiológico, temprano y prospectivo, para personas tratadas por cáncer de mama.

Breast cancer is a public health problem in Chile and the world due to high incidence. Surgery is the mainstay in the breast cancer treatment. Up to 60% of people receiving this management have functional morbidity in the upper limb. There are rehabilitation health models care for the functional morbidity, however, in Chile is not a standard in the health care. This article describes: 1) upper limb morbidity secondary to breast cancer surgery, and 2) early and prospective physical Therapy model care for people with breast cancer.

Tumor de células gigantes en el antebrazo / Forearm giant cell tumor

RESUMEN El tumor de células gigantes se define como un tumor óseo benigno que invade las partes blandas localmente de forma agresiva. Se presenta una paciente con un tumor de células gigantes recidivante en el tercio distal del radio derecho, con signos de necrosis superficial e infección sobreañadidos, la cual, dada la magnitud y severidad de la lesión, requirió una amputación supracondílea de la extremidad. Presentó una evolución postoperatoria favorable, con recuperación física y psicológica(AU)

ABSTRACT Giant cell tumor is defined as a benign bone tumor that aggressively invades soft tissue locally. We present a patient with a recurrent giant cell tumor in the distal third of the right radius, showing signs of superimposed necrosis and infection, which, given the injury magnitude and severity, required supracondylar amputation of the limb. Her postoperative evolution was favorable, and this patient underwent physical and psychological recovery(AU)

RÉSUMÉ La tumeur à cellules géantes est définie comme une tumeur osseuse bénigne qui envahit agressivement les parties molles locales. Une patiente atteinte de tumeur récidivante à cellules géantes au niveau du tiers distal du radius droit, avec signes de nécrose superficielle et d'infection surajoutés, laquelle a requis une amputation supracondylienne du membre, due à la magnitude et à la sévérité de la lésion, est présentée. Elle a montré une évolution postopératoire favorable, avec une bonne récupération physique et psychologique.

Arteria ulnar superficial, bilateral y antebraquial: similitudes y diferencias / Superficial ulnar artery, bilateral and antebrachial: similarities and differences

Describimos un hallazgo infrecuente de arteria ulnar superficial en ambos antebrazos de un cadáver, con origen en la arteria braquial, a nivel de la fosa cubital. Las arterias presentan un trayecto que dividimos en cuatro segmentos, a causa de sus flexuosidades. Ambos antebrazos presentan ausencia del músculo palmaris longus. Se resumen las principales teorías sobre su desarrollo y las complicaciones que pueden ser ocasionadas por su presencia y el eventual beneficio de la misma. Hasta el momento, no hemos encontrado en la literatura, una disposición morfológica de arterias ulnares superficiales como las aquí descritas.

We describe an infrequent finding of a superficial ulnar artery in both cadaver forearms, which originates in the brachial artery at cubital fossa level. The arteries have a path that we divided into four segments, because of their flexuosities. Both forearms showed an absence of the palmaris longus muscle. This summarizes the main theories about its development and the complications and eventual benefits that can be caused by its presence. So far, we have not found in the literature, a morphological disposition of superficial ulnar arteries such as those described here.
