Introduction: revision joint replacement surgery presents a surgical challenge. The use of rotating hinge prostheses is an option in patients with femorotibial bone defects, ligament insufficiency, or significant deformities. The aim of this study was to evaluate the clinical, functional, and radiological outcomes of a series of patients who underwent surgery using the GMK Hinge (Medacta®) rotational hinge model. Material and methods: a descriptive, retrospective, and analytical study was conducted on a series of 36 patients, with a mean age of 72.5 years (47-85), operated on by the same surgical team between January 2015 and January 2022. The etiology of revision was chronic infection in 38.9% of cases, instability in 33.3%, aseptic loosening in 19.4%, and stiffness in 8.4%. The Knee Society Score (KSS) and the Forgotten Joint Score (FJS) were used to assess functional outcomes. The degree of femorotibial bone defect was evaluated using the Anderson Orthopaedic Research Institute (AORI) classification. Postoperative complications are also recorded. Results: a total of 36 patients, 17 males and 19 females, were included, with a mean follow-up of 30 months (12-66). Twelve patients had type 1 defects, ten had 2A defects, ten had 2B defects, and two had type 3 defects on the femoral side, with the use of wedges required for asymmetrical defects (21 patients). The predominant tibial defect was type 1 without the need for wedges. The majority achieved a satisfactory outcome on the KSS scale (72.2 ± 9.4), with significant differences compared to the previous KSS (54.3 ± 8.9). A score of 31 (12-67) was also obtained on the FJS scale. Postoperative complications were present in 16.7% of patients. Conclusions: complex prosthetic revision surgery using a rotating hinge prosthesis represents a suitable therapeutic option, yielding appropriate clinical and functional outcomes, albeit not without complications.

Objetivo. Comparar los resultados sanitarios y económicos de dos sistemas de adquisición de prótesis: un sistema tradicional en el cual la compra se inicia al solicitar el insumo versus un modelo de insumos en existencia denominado Banco de Prótesis. Métodos. Estudio descriptivo-analítico, en usuarios del Ministerio de Salud de la provincia de Buenos Aires, Argentina. Los pacientes pertenecían a dos grupos de estudio 1) prótesis provistas por vía tradicional del Sistema Informático para Adquisición y Contrataciones Hospitalarias (SIPACH); 2) prótesis provistas por Banco de Prótesis (BDP). Se limitó el análisis a prótesis endovasculares del tipo stent coronario y prótesis de cadera. Se utilizaron bases de datos oficiales gubernamentales. El periodo de estudio comprendió del 01/01/2018 hasta el 31/10/2022. Las variables analizadas fueron: edad, sexo, diagnóstico, hospital, tipo de implante o prótesis; fecha solicitud; fecha adquisición; precio unitario, costos directos e indirectos; costos promedio de la internación diaria, costo-efectividad e impacto presupuestario. Resultados. Se analizaron 4 106 solicitudes. En el sistema tradicional, 13,5% de los pacientes no consiguieron sus prótesis, hubo 50 días más de demora que con BDP, y los costos totales fueron superiores en SIPACH (stent coronarios +463%, prótesis de cadera +133%). El BDP ahorró US$ 3,2 millones anuales y evitó 22 muertes con la provisión temprana de prótesis endovasculares. Conclusiones. El BDP demostró superioridad al modelo tradicional de provisión de prótesis tanto en términos sanitarios, por lograr mayor acceso, acortar tiempos de espera y evitar muertes; como económicos, por reducir significativamente los precios unitarios y globales, logrando un notable ahorro en los presupuestos asignados.

Introduction: parosteal osteosarcoma is an extramedullary malignant bone tumor in which cells produce osteoid, represents less than 5% of all osteosarcomas, it occurs predominantly in women between the second and fourth decade of life. It is often located in the distal region of the femur and proximal tibia. Clinically it presents with increased volume and thigh or knee pain. Due to its low incidence and clinical features, a clinical case of femoral parosteal osteosarcoma is presented, with description of the surgical technique performed. Case report: a 14-year-old female presented with a 6-month history of increased volume and right thigh pain. Radiological studies revealed a bone lesion with malignant characteristics, for which she was sent to third-level hospital where oncology study protocol was set up; consisting in two percutaneous biopsies of the lesion with Jamshidi needle, which were histopathology reported as negative for malignant cells. The pulmonary high-resolution computed tomography showed metastasis and a Tc-99m MDP bone scintigraphy showed increased osteoblastic activity in the right femoral shaft. Given the results, is confirmed the need of en-bloc resection and intercalary prosthesis implantation with adjuvant chemotherapy. Conclusion: the intercalary prosthesis is a suitable therapeutic option in limb-salvage surgery for patients with femoral parosteal osteosarcoma. [ABSTRACT FROM AUTHOR]

The article presents the design of a new model of functional transtibial prosthesis that simulates the anatomical behavior of the tibioperoneo-astragalus joint. The design aims to improve gait biomechanics and reduce impact on the stump and gait alterations. The design of a new transtibial prosthesis is proposed that meets the requirements of human body functioning and improves body biomechanics. The model includes a spring system that allows for energy displacement during gait and has hydraulic, pneumatic, and electric actuators. This innovative design provides support in different anatomical positions of the human body and during gait. [Extracted from the article]

Background: Obesity is a global public health challenge, closely related with the progression of other diseases. In recent years, odontology has intervened against obesity through the implementation of intraoral devices that contribute with weight control treatments. Objective: To study the use of a dental occlusal disruptor as a strategy to moderate caloric intake. Material and methods: Pilot study which included 2 patients. It was used a dental occlusal disruptor that has an impact on the smaller amount of food at each bite. Patients attended five appointments in which a stomatological evaluation was carried out and anthropometric measurements were taken. All adverse effects were reported in each patient's clinical history. Results: Patients presented weight and body fat loss, increased muscle mass and decreased both body mass index and waist and hip measurements. Conclusions: The use of the disruptor does not alter the stomatological assessment, it promotes masticatory regulation and the decrease in body weight. It is necessary to analyze its use in a larger number of patients. [ABSTRACT FROM AUTHOR]

En un paciente con artrosis unicompartimental de rodilla grave, donde se agotaron los tratamientos conservadores que tiene clínica dolorosa localizada en el lado afectado y con alteración del eje reductible, la prótesis unicompartimenal de rodilla (PUR) es la primera opción para nuestro grupo de trabajo. Dentro del estudio para confirmar el diagnóstico y planificar la cirugía destacan las radiografías de rodillas con carga, radiografía de Rosenberg y telerradiografías de extremidades inferiores. El objetivo de la cirugía es reemplazar la zona afectada, restituyendo la anatomía con un adecuado balance de partes blandas. Respecto al alineamiento el desafío es no sobrecargar el lado contrario ni tampoco el de la prótesis. Existen de platillo móvil y fijo y aunque los resultados clínicos y de supervivencia son semejantes, en los últimos años con la incorporación de la cirugía robótica, la balanza se ha inclinado para el uso de los platillos fijos. En pacientes con artrosis unicompartimental los resultados clínicos y funcionales son mejores con PUR y tiene menos complicaciones que cuando se usan prótesis totales (PTR). La supervivencia estudiada en registros es menor que para PTR, pero cuando se usa en centros de alto flujo en que el porcentaje de PUR es cercano a un tercio del total con una estricta selección de pacientes, la duración es tan buena como en la PTR.

Objective: To analyze the results of endovascular treatment of venous anastomotic stenosis (VAS) in humero-axillary arteriovenous grafts (HAG), comparing outcomes between patent and thrombosed HAG. Material and methods: A retrospective cohort study was made of endovascular treated patients because of a VAS in a HAG between January 2009 and December 2019. Group A: Thrombosed HAG secondary to a VAS. Group B: Patent HAG with a VAS detected during follow-up. Technical success was defined as residual stenosis after treatment

Background and objective. Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a rare and partially understood disease that has aroused great interest due to the social and economic impact it generates. Little is known about the possible occurrence of the disease associated with the use of implants in other body locations. The objective of this article is to characterize and present the cases of anaplastic large cell lymphoma associated with implants located outside the breast described in the literature. Methods. A review of the literature was performed in PubMed, Cochrane, ScienceDirect and SciELO databases looking for reports of implant-associated anaplastic large cell lymphoma (IA-ALCL) in sites other than the breast. Results. Two case reports of IA-ALCL in the buttocks were found in patients with previous augmentation gluteoplasty with implants performed for aesthetic purposes. Additionally, the finding of a greater number of other types of lymphomas associated with the placement of different devices for medical use and the application of gluteal biopolymers in an additional case. Conclusions. The existence of a new disease associated with silicone implants in other body sites is possible. The literature is scant and does not allow us to confirm its existence. There must be a high index of suspicion in any case suggestive of the entity for its study, proper classification and timely management. We propose a diagnostic algorithm that can be very useful in patients with gluteal implants who present some associated symptoms. [ABSTRACT FROM AUTHOR]

Introduction: The repair of suprapubic incisional hernias represents a complexity due to its proximity to the bony flange of the pelvis and neurovascular structures such as epigastric arteries and iliac package, the difficulty of adequate adaptation and a good margin of prosthesis protection. Material and methods: Retrospective observational analysis of the HIS repaired in our hospital between January 1, 2012 to January 1, 2019. Abdominal CT was performed preoperatively in Valsalva to all patients. The variables related to the applied surgical treatment, postoperative complications and the overall recurrence rate were studied. Results: 25 patients with HIS were operated. Only 20 % of the incisional hernias were pure suprapubic (M5), the mean hernia transverse diameter being 7.7 cm. In 4 cases, preoperative administration of botulinum toxin and progressive pneumoperitoneum was necessary. All patients underwent a Stoppa repair. Postoperative morbidity was 28 %, mostly related to the surgical wound, although a patient died due to an intestinal fistula. The mean postoperative follow-up was 29 months, not finding hernia recurrence. Conclusions: In our experience, the repair of suprapubic incisional hernias is complex, with no negligible morbidity, but acceptable rates of hernia recurrence. [ABSTRACT FROM AUTHOR]

Introduction: Complex incisional hernia is an unusual pathology, although its incidence is increasing. It requires great knowledge of the anatomy of the abdominal wall and advanced methods for its preparation and treatment. In addition, it includes greater postoperative morbidity and long-term recurrence. Material and methods: A bibliographic research was carried out from August 2009 to February 2021 using the keywords complex ventral hernia, incisional hernia, hernia with loss of domain, incisional giant hernia, progressive pneumoperitoneum, botulinum toxin A and hernia, anatomic component separation and complex abdominal wall reconstruction. A total of 68 articles in English and Spanish were used to carry out the present review. Conclusion: Complex incisional hernia is a challenge for surgeons and an important disability for patients. Advances in patient optimization, tomographic measurements, and adjuvant pre and intraoperative techniques have contributed to restoring the anatomy and function of the abdominal wall, maintaining its innervation with acceptable morbidity and recurrence.

En pacientes frágiles, generalmente ancianos, las caídas son la principal causa de visitas a las emergencias. Un tercio de las personas ≥65 años se cae cada año, y en 1 a 5% de estas caídas ocurre una fractura, siendo las de fémur proximal muy frecuentes. La incidencia de fracturas femorales proximales, así como el uso de los dispositivos de osteosíntesis asociados a estas, continúa en ascenso, al igual que la incidencia de caídas recurrentes y fracturas reincidentes, conocidas como peri-implante y peri-protésicas. La literatura reporta escasamente estas lesiones, por lo que no existe estandarización en el tratamiento. Presentamos el caso de una paciente femenino de 92 años de edad, quien 20 meses posterior a enclavado endomedular por fractura pertrocantérica de femur derecho, sufre nueva caída y re-fractura en femur proximal, de tipo peri-implante. En vista de tratarse de hueso osteopénico y de ser una paciente activa, se decide realizar nueva síntesis de fractura combinando un sistema novel de clavo-placa-guayas bajo el principio de solidarización o solapamiento de implantes con resultados satisfactorios y retorno a sus actividades cotidianas. Concluimos que la aplicación de dicho principio es reproducible y segura, sin embargo, el tratamiento debe ser personalizado en estos patrones de fracturas/patologías infrecuentes, tomando en consideración las demandas biomecánicas de cada paciente.

In recent years, aesthetic dentistry has become a major focus for the public. Facial attractiveness plays a key role on modern society and the creation of harmonious smile is an aim for every dentist. The objective of this study was to define certain values of the inter-incisive index in Bulgarians, the sexual dimorphism and bilateral asymmetry and to verify differences of this index between Bulgarians and other Balkan populations. The present study included 121 males and 111 females of Bulgarian origin aged 20-40 years. Mesiodistal dimensions of maxillary central and lateral incisors were measured by Dentistry Sliding Vernier Caliper. We used the technique of direct anthropometry, modified by Prof. Y. Yordanov. We calculated the inter-incisive index as ratio of the mesiodistal dimension of maxillary lateral incisor to the mesiodistal dimension of the maxillary central incisor. The measurements were analyzed with SPSS 23. The level of statistical significance was set at P< 0.05. The inter-incisive index showed no statistically significant differences between left and right side of the dental arch in both sexes. We did not find statistically significant differences between males and females as well. On the other hand, we found statistically significant differences in MD values of incisors between Bulgarians and other Balkan nations. Inter-incisive index shows no sexual dimorphism and bilateral asymmetry in Bulgarians. This can be helpful in aesthetic dentistry, in prosthodontics and in orthodontic treatment planning.

El reemplazo total de rodilla (RTR) es un procedimiento quirúrgico, indicado en pacientes que presentan osteoartrosis severa (grado III - IV) de la articulación. Se han desarrollado diversas técnicas de analgesia para disminuir el dolor en el RTR. Objetivo: Evaluar la eficacia del bloqueo capsular versus bloqueo por infiltración entre la arteria poplítea y la cápsula de la rodilla (IPACK) en el manejo del dolor en pacientes tratados con RTR. Materiales y métodos: Se realizó un estudio observacional, analítico, de cohorte prospectivo, durante 10 meses, en 20 pacientes con artrosis severa de rodilla, corroborada por estudio de imágenes. A 10 pacientes se les aplicó el bloqueo IPACK guiado bajo ecografía con levobupivacaína y a los otros 10 pacientes se les aplicó el IPACK con la mezcla de Ranawat luego del cementado de la prótesis durante el acto quirúrgico. En un segundo tiempo, a las 24 y 48 horas del postoperatorio se aplicó un instrumento de evaluación para determinar la funcionalidad de la rodilla considerando los grados de flexión y el nivel de analgesia mediante la escala visual análoga del dolor (EVA). Resultados: No se presentaron diferencias significativas entre ambas técnicas anestésicas, sin embargo los grados de flexión con el bloqueo capsular fueron más altos con respecto al bloqueo IPACK así mismo que con la escala visual análoga del dolor. Conclusión: Los dos bloqueos resultan ser eficientes para el manejo del dolor postoperatorio en pacientes con reemplazo articular de rodilla.

Introduction: Major orthopedic surgery such as total hip arthroplasty (THA) is associated with an increased risk of postoperative complications. Candidates for THA are often older adults, with comorbidities that increase the risk of major bleeding, the IMPROVE scale has independent actors on the risk of bleeding according to the characteristics of the patients at hospital admission. It foresees the possibility of hemorrhage and the need for blood transfusion, being support in decision-making in the planning of a safe THA with the provision of the necessary resources. Objective: To evaluate the sensitivity, validity and reliability of the modified IMPROVE scale in patients undergoing primary total hip arthroplasty. Material and methods: Study of processes with a sample of 131 patients undergoing primary THA, in the period from January 01, 2018 to July 01, 2018. Results: The scale presents good reliability, as for the performance of the scale, a good sensitivity was obtained, classifying 96.9% of the patients correctly; which is suitable for the type of scale. Conclusions: The modified IMPROVE scale is a discretely adequate and useful tool for the prognosis of bleeding risk in patients who undergo THA, compared with other assessment scales developed in other geographical areas. It is recommended to continue with the study of risk factors for major bleeding in this specific population. [ABSTRACT FROM AUTHOR]

Introducción. Por ser un procedimiento de mínima invasión, la colangiopancreatografía retrógrada endoscópica (CPRE) es el procedimiento más utilizado para el manejo de la patología litiásica biliar. Sin embargo, puede presentar complicaciones que comprometen la vida del paciente. Caso clínico. Paciente masculino de 63 años es llevado a CPRE por una coledocolitiasis recidivante gigante. Durante el procedimiento presentó una disección aérea masiva con neumotórax bilateral a tensión, secundarios a una perforación duodenal, que derivó en una fístula bilio-retroperitoneal. Se trató de forma conservadora con una adecuada evolución. Discusión. Se han descrito pocos casos de neumotórax como complicación de la CPRE. Se considera que este es el primer caso publicado de neumotórax a tensión manejado exitosamente de forma conservadora. Conclusión. El diagnóstico temprano de las disecciones aéreas es el único predictor independiente que podría cambiar el curso clínico de esta patología y su manejo dependerá de la experticia del cirujano y del estado clínico del paciente.

En este artículo se reflexiona sobre la influencia que la narración tiene en la vida de los seres humanos. Se conecta este hecho con el concepto de ‘prótesis cultural’ de Roger Bartra. Y finalmente se utiliza dicha noción, una vez equiparada con la idea de ‘suplemento’ derridiano, para hacer una interpretación alternativa del episodio LXXIIII de Don Quijote de la Mancha.

This essay charts the role of armor in Renaissance practices of knowledge. Since the advent of gunpowder warfare, armor was largely unfit for combat, yet still became a centerpiece of princely representation and was prominently displayed in early collection spaces. Rather than illustrating chivalric virtues or antiquarian taste, such suits in my reading signal a shift towards a physiological fashioning of learning. Through juxtaposing two key sets of armor – one ‘gothic’ suit situated in the studiolo, the other a ‘grotesque’ garniture for a chamber of curiosities –, my paper traces how these embodied settings conflated epistemological with political sensibilities. While the earlier ensemble acted as a mnemonic ‘prosthesis’ that enhanced the mind of the wearer, the latter evoked natural history imagery to remap the order of things around personal authority. Objects of armor thus spotlight the interplay of material and political culture in engineering the early modern subject. El presente ensayo traza el papel de las armaduras en las costumbres renacentistas del conocimiento. Desde la aparición de las armas de pólvora, las armaduras dejaron de ser apropiadas para el combate, si bien todavía constituyeron una pieza central de representaciones principescas y fueron ampliamente expuestas en espacios de colección. En lugar de ilustrar las virtudes caballerescas o los estilos como antigüedades, estas vestimentas señalan, a mi entender, un giro hacia el conocimiento fisiológico de la moda. A través de la yuxtaposición de dos conceptos clave de las armaduras –uno como vestimenta gótica emplazada en el studiolo (taller de arte), otro como decoración «grotesca» en una sala de curiosidades – mi texto indaga cómo estos elementos ajustados al cuerpo confrontaban las sensibilidades epistemológicas y políticas. Mientras que las primeras actuaban como una prótesis que fortalece la mente del que las usa, las segundas evocan la imaginería de la historia natural para recolocar el orden de las cosas alrededor de la autoridad personal. Las armaduras enfocan de este modo la interacción entre la cultura material y la política en el desarrollo del sujeto moderno.

Introducción: la satisfacción de pacientes es importante en la adopción de medidas para la mejora continua de la calidad. Objetivo: evaluar el nivel de satisfacción de los pacientes atendidos en el servicio de Prótesis de la Clínica Estomatológica Docente “Lidia Doce Sánchez” Método: se realizó un estudio longitudinal prospectivo, el universo estuvo constituido por 171 pacientes que ingresaron en el servicio durante el período, al aplicar los criterios de inclusión y exclusión quedaron 160. Se definieron las variables: grupos de edades, sexo, nivel de satisfacción de los pacientes por el tiempo de atención, las condiciones de la sala de espera, las condiciones estructurales de la consulta y el tratamiento recibido. Para la recolección de la información se diseñó y validó un cuestionario mediante el criterio de expertos. Resultados: el 60 % mostró insatisfacción con el tiempo para ingresar en el servicio y con las sillas o bancos el 43,8 %. En la consulta mostró satisfacción con las condiciones del sillón dental el 46,8 % y con la limpieza y organización el 76,8 %, con la ventilación e iluminación el 39,5 % refirió insatisfacción. Conclusiones: la mayoría mostró insatisfacción con el tiempo de espera para el ingreso, con los bancos y sillas de la sala de espera y la ventilación e iluminación de la consulta. La mayoría mostró satisfacción con el tratamiento recibido.

Introduction: Total knee arthroplasty (TKA) is one of the most successful orthopedic treatments, however, it has been associated with severe postsurgical pain in 30-60% of patients. We propose that infiltration of the articular capsule of the knee during surgery will decrease postsurgical pain. Material and methods: Experimental, randomized, double-blind study in patients undergoing unilateral TKA between April 2018 and January 2019. Patients were divided into two groups, the first infiltration with placebo and the second with anesthetic solution and adjuvants (fentanyl, epinephrine and ketorolac). Pain was measured with the visual analog scale (VAS) at 4, 6, 8, 12, 18, 24, 36 and 48 hours postsurgical, as well as the consumption of opioid analgesics and antiemetics. Results: 20 patients in each group, with a follow-up of 4 weeks. There were no significant differences in demographic characteristics between the two groups. Better control of postsurgical pain was observed in the group that received infiltration with anesthetic and adjuvant, as well as a decrease in the consumption of opioid analgesics and antiemetics. There was no difference in bleeding or in the incidence of infections between the two groups. Conclusion: Peri-capsular infiltration is a safe and effective method, as part of multimodal analgesia in total knee arthroplasty, as it decreases postsurgical pain, opioid and antiemetic use and does not increase postsurgical bleeding.

Introduction: There is still controversy regarding thrombo-prophylaxis for the reduction of thromboembolic disease in major orthopedic surgery. Objective: To answer the following question: is there a difference in the effectiveness and safety in the antithrombotic management of patients with a traditional regimen of enoxaparin against acetyl salicylic acid? Material and methods: The surgeries were performed by 3 surgeons; the sample was randomized and the patients were subjected to the study criteria. We evaluated efficacy and safety as well as the need for readmission and secondary variables such as infection, acute myocardial infarction (AMI), cerebral vascular disease and death with a followup of 90 days. Results: The total sample was 402 patients; 214 in the enoxaparin group and 188 in the aspirin group. There were 5 cases (1.24%) with thromboembolic disease, 3 (1.4%) enoxaparin and 2 (1.06%) aspirin without significant difference (p = 0.23). In terms of safety, major bleeding was zero in both groups, with minor bleeding in 7 patients (1.74%), 4 (1.86%) were from the enoxaparin group and 3 (1.59%) from the aspirin group without significant differences (p = 0.82). Secondary outcomes showed 5 (1.24%) superficial surgical wound infections and one AMI in the first 30 days of the procedure in the enoxaparin group. Conclusion: Aspirin as monotherapy is safe, effective in antithrombotic prophylaxis in patients operated on total knee arthroplasty. [ABSTRACT FROM AUTHOR]
