ABSTRACT

Objetivo. Estudiar los resultados del tratamiento de la seudoartrosis de escafoides, con dudosa viabilidad del fragmento proximal, pero sin deformidad ni colapso importante del mismo, mediante la utilización de un injerto óseo vascularizado de la arteria suprarretinacular 1,2 intercompartimental (1,2 ICSRA) y osteosíntesis posterior. Material y método. Estudio retrospectivo de 10 pacientes varones con diagnóstico radiográfico de seudoartrosis. Después del tratamiento se evaluó la funcionalidad, el dolor medido por la escala analógica visual (EVA), la fuerza de agarre, la satisfacción del paciente y la reintroducción a la vida laboral, utilizando las escalas de Mayo y QuickDASH específicas de muñeca y comprobándose radiográficamente la integración del injerto. Resultados. El seguimiento medio fue de 31,4 meses; un 90% de las encuestas fueron satisfactorias. La EVA descendió en 4,6 puntos y la ganancia de movilidad flexo-extensora fue de 5°. La tasa de consolidación completa del injerto alcanzó el 40% en 5,5 meses de media. Discusión. Diferentes estudios han demostrado mejores resultados utilizando injerto óseo vascularizado frente al no vascularizado. Desde la descripción por Zaidemberg en 1991, el injerto microvascularizado con arteria 1,2 ICSRA, de radio distal, ha sido el más utilizado para el tratamiento de seudoartrosis del escafoides. Conclusiones. Nuestros resultados, comparables con la bibliografía revisada, utilizando el injerto vascularizado de arteria 1,2 ICSRA y osteosíntesis con tornillo tipo Herbert, pueden ser una alternativa de tratamiento para la seudoartrosis proximal de escafoides, sin colapso ni deformidad importante (AU)


Objective. To analyze the results of treatment of scaphoid nonunion with questionable viability of the proximal fragment, but without significant deformity or collapse, using a vascularized bone graft of 1,2 intercompartmental supraretinacular artery (1.2 ICSRA) and subsequent osteosynthesis. Material and method. A retrospective study was performed on 10 male patients with a radiographic diagnosis of nonunion. Functionality, pain using Visual Analog Score (VAS), grip strength, patient satisfaction and reintroduction to working life, using QuickDASH and May specific wrist scales were assessed after the treatment. The integration of the graft was checked by radiography. Results. The mean follow-up was 31.4 months, and 90% of the questionnaires were satisfactory. The VAS decreased by 4.6 points and the flexor-extensor mobility gain was 5°. The total graft consolidation rate reached 40% in 5.5 months on average. Discussion. Several studies have demonstrated better results using vascularized bone graft versus non-vascularized. From the description by Zaidemberg in 1991, the vascularized graft with 1.2 ICSRA artery, distal radius, has been the most widely used for the treatment of scaphoid nonunion. Conclusions. Our results are comparable with the literature reviewed, thus using vascular graft of the 1.2 ICSRA and osteosynthesis with Herbert-type screw, may be an alternative treatment for proximal scaphoid nonunion, without collapse or significant deformity (AU)

ABSTRACT

Objetivo. Estudio epidemiológico y funcional a largo plazo de las fracturas de pilón tibial ingresadas en nuestro servicio a lo largo de cinco años cuyo objetivo es determinar cuál fue la evolución a largo plazo de las mismas, analizar la posible influencia de la calidad de la reducción obtenida y del estado de las partes blandas en los resultados clínicos, y evaluar la relación existente entre el tipo de fractura, los signos degenerativos radiográficos y los resultados obtenidos.Material y método. Se revisan 91 fracturas de pilón tibial en 87 pacientes (4 bilaterales), de las que 29 fueron mujeres (31,9%) y 62 varones (68,1%). Se realiza un estudio retrospectivo de todas las historias clínicas, citando posteriormente a los pacientes para la encuesta de funcionalidad según la escala de Duquennoy para el tobillo, la valoración objetiva de parámetros y la actualización de las radiografías.Resultados. Los factores más afectados por la fractura, en la escala de valoración de Duquennoy, fueron la capacidad de carrera/salto con una media de 1,6/5 y la deambulación sobre terrenos irregulares (2,6/5); los que menos se vieron influidos por la lesión fueron la necesidad de utilizar bastones (4,3/5) y el perímetro de marcha (8,4/10). Destaca un elevado número de complicaciones iniciales para reducir (27,1%) y/o fijar (12,8%) la fractura; complicaciones precoces comoproblemas en las partes blandas perifractuarias, y destacando entre las tardías la gran incidencia de la rigidez articular (51,4%) y las consolidaciones viciosas (24,3%).Conclusiones. Las fracturas de pilón tibial habitualmente se asocian a una alta tasa de complicaciones que hace muy difícil la predicción de los resultados a largo plazo. Existe una relación directa entre la existencia de signos radiográficosde artrosis y los malos resultados obtenidos con el paso del tiempo. Una excelente reducción articular no asegura unos excelentes resultados a largo plazo, pero sí una mayor probabilidad de que éstos estén presentes (AU)


Purpose. This is a functional and epidemiological long-term study of tibial pilon fractures treated in our hospital over a five-year period. Our aim was to determine the long-term evolution of these fractures, to assess the potential effect of the quality of the reduction obtained and of the condition ofthe soft tissues on the final outcome and to evaluate the relationship between fracture type, radiographical degenerative signs and the results obtained.Materials and methods. Ninety-one tibial pilon fractureswere reviewed in 87 patients (4 bilateral ones), 29 of which were women (31.9%) and 62 men (68.1%). A retrospective study was carried out of all clinical records, further to which patients were called in to be evaluated with respect to the Duquennoy ankle scale and to have their parameters objectively assessed and their radiographs updated.Results. On the Duquennoy scale, the factors most significantly affected by the fracture were the ability to run and to jump, with a mean value of 1.6/5 points and walking on uneven ground (2.6/5). The factors least affected by the injury were the need of a walking-stick (4.3/5) and the gait perimeter (8.4/10). There was a high incidence of initial complications to reduce (27.1%) and/or fixate (12.8%) the fracture. There were also a few early complications such as soft tissue-related problems in the area around the fractureand some late complications such as a high incidence ofjoint stiffness (51.4%) and malunions (24.3%).Conclusions. Tibial pilon fractures are often associated to a high complications rate that makes it very difficult to anticipate long-term results. There is a direct relationship between the presence of radiographic signs of arthritis and poor long-term results. An excellent joint reduction does not guaranteethe attainment of excellent long-term results; but it does lead to a higher probability of success (AU)

ABSTRACT

Objetivo. El objetivo de este trabajo es comprobar si la hemostasia quirúrgica que se realiza tras la retirada del torniquete en las prótesis totales de rodilla es efectiva para reducir las pérdidas sanguíneas. Material y método. Se seleccionaron 30 pacientes, a los que se les realizó hemostasia con electrobisturí una vez retirado el torniquete (grupo A) y otros 30 pacientes a los que se les retiró el torniquete una vez cerrada la herida y aplicado el vendaje compresivo (grupo B). Se midieron las pérdidas sanguíneas recogidas por el drenaje aspirativo, los descensos de hemoglobina y hematocrito a las 24 y 48 horas después de la cirugía comparados con los preoperatorios, tiempos de isquemia e intervención y necesidades transfusionales. Resultados. No se encontraron diferencias estadísticamente significativas en cuanto a las pérdidas sanguíneas (p = 0,836) y requerimientos transfusionales (p= 0,618) entre ambos grupos. Conclusiones. La hemostasia quirúrgica que se realiza una vez retirado el torniquete no es efectiva para reducir las pérdidas sanguíneas en la artroplastia de sustitución de la rodilla


Purpose. The purpose of this study is to determine if surgical hemostasis carried out after tourniquet removal in total knee replacement (TKR) surgery is effective in reducing bleeding. Materials and methods. In 30 selected patients (Group A) undergoing TKR hemostasis was carried out with electrocautery once the tourniquet was deflated intraoperatively; in another 30 selected patients (Group B) the incision was closed and compressive dressing was applied before tourniquet removal. Blood loss was measured by aspiration drainage, and hemoglobin levels and hematocrit were measured at 24 and 48 hours after surgery and compared with preoperative values, ischemic time was also measured and any transfusions required registered. Results. No statistically significant differences were found between both groups regarding blood loss (p=0.836) or transfusions required (p= 0.618). Conclusions. Surgical hemostasis carried out after tourniquet removal is not effective as a way of reducing blood loss in total knee replacement (TKR)
