ABSTRACT
Introducción: La cirugía de revisión acetabular supone un reto quirúrgico sobre todo cuando aparecen los defectos óseos complejos, pues dificultan la fijación primaria y osteointegración de los implantes, lo que condiciona la aparición de complicaciones. Los cotilos de titanio trabecular intentan solventar estos problemas. Objetivos: Valorar los resultados clínico-radiológicos, la supervivencia de los implantes y aparición de complicaciones a medio plazo en cirugía de revisión acetabular en una serie de 37 recambios acetabulares con defectos óseos tipo IIIA y IIIB de Paprosky en los que se utilizó un implante de revisión tipo Cup-Cage de titanio trabecular. Material y método: Realizamos un estudio observacional, descriptivo y retrospectivo de 37 casos con defectos acetabulares complejos (20 tipo IIIA y 17 tipo IIIB, cinco de ellos con discontinuidad pélvica) en los que se realizó recambio del componente acetabular por implantes de titanio trabecular entre los años 2011 y 2019. Analizamos resultados clínicos (dolor y funcionalidad) y parámetros radiológicos (restauración del centro de rotación de la cadera y la movilización de los implantes), así como la aparición de complicaciones. Resultados: El seguimiento medio fue de 61 meses. Obtuvimos una mejoría en la mediana de 8 puntos en la escala de funcionalidad de Merlé DAubigné-Postel y de 6 puntos en la escala EVA de dolor percibido por el paciente. Registramos dos casos de aflojamiento acetabular, un caso de inestabilidad y tres infecciones de herida quirúrgica sin afectar al implante. Conclusiones: La utilización de implantes tipo Cup-Cage de titanio trabecular podría constituir una opción válida en cirugía de revisión acetabular con defectos acetabulares complejos, presentando buenos resultados clínico-radiológicos y en cuanto a complicaciones y supervivencia de los implantes, debido a su buena fijación primaria y osteointegración.(AU)
Introduction: Acetabular revision surgery is a surgical challenge, especially when complex bone defects appear. This makes primary fixation and osseointegration of the implants difficult, which conditions the appearance of complications. Trabecular titanium implants attempt to solve these problems. Objectives: To evaluate our clinical-radiological results, the survival of the implants and the appearance of mid-term complications in acetabular revision surgery in a series of 37 acetabular replacements with Paprosky type IIIA and IIIB bone defects in which a trabecular titanium Cup-Cage revision implant was used. Material and method: We conducted an observational, descriptive and retrospective study of 37 cases with complex acetabular defects (20 type IIIA and 17 type IIIB, five of them with pelvic discontinuity) in which the acetabular component was replaced by trabecular titanium cups between 2011 and 2019. We analyzed clinical results (pain and functionality) and radiological parameters (restoration of the hip rotation centre and the mobilization of the implants), as well as the appearance of complications. Results: The mean follow-up was 61 months. We obtained a median improvement of 8 points on the Merlé DAubigné-Postel functionality scale and 6 points on the VAS scale of pain perceived by the patient. We recorded two cases of acetabular loosening, one case of dislocation and three surgical wound infections without affecting the implant. Conclusions: The use of trabecular titanium Cup-Cage implants could be a valid option in acetabular revision surgery with complex acetabular defects, presenting good clinical and radiological results and in terms of complications and survival of the implants, mainly due to their good primary fixation and subsequent osseointegration.(AU)

Introducción Las fracturas del tercio distal de tibia son en su mayoría consecuencia de un traumatismo de alta energía con importante afectación de partes blandas siendo mas frecuentes en varones. Este tipo de fracturas se diferencian de la fractura articular de pilón tibial en su mecanismo de lesión, manejo y pronóstico. El objetivo del presente estudio fue analizar y comparar los resultados obtenidos en el tratamiento de las fracturas de tercio distal de tibia sin extensión articular mediante placa bloqueada y clavo intramedular. Material y métodos: Realizamos un estudio retrospectivo en el que se incluyeron todos los pacientes con diagnostico «fractura de tercio distal de tibia» segmento 43A según la clasificación propuesta por «Trauma Orthopedic Association» intervenidos entre enero del 2015 y mayo del 2019. Obtuvimos 24 pacientes intervenidos mediante clavo intramedular y 29 mediante placa bloqueada. Resultados: La muestra incluyó 53 pacientes (36 varones y 17 mujeres) con una media de edad de 51 años (rango: 15-77 años). El tiempo de seguimiento medio fue de 6 meses (3-30 meses). No se hallaron diferencias significativas en el tiempo de consolidación de la fractura, aunque el inicio de la deambulación con carga fue mas temprano en el grupo clavo. Discusión: En la actualidad no existe consenso acerca del manejo terapeútico de las fracturas distales de tibia sin extensión articular. Conclusiones: Dados los resultados obtenidos consideramos que tanto la osteosíntesis con clavo intramedular como con placa bloqueada son opciones válidas en el tratamiento de las fracturas del tercio distal de tibia.(AU)
Introduction: Fractures of the distal third of the tibia are mostly the consequence of high-energy trauma with significant soft tissue involvement, being more frequent in men.These types of fractures differ from the tibial pilon joint fracture in their mechanism of injury, management and prognosis. The objective of the present study was to analyze and compare the results obtained in the treatment of fractures of the distal third of the tibia without joint extension using a locked plate and intramedullary nail. Material and methods: We carried out a retrospective study with patients diagnosed of distal third tibia fracture segment 43A according to the classification proposed by the Trauma Orthopedic Association who were intervened between January 2015 and May 2019 were included. We obtained 24 patients intervened with a nail intramedullary and 29 using a blocked plate. Results: The study included 53 patients, 36 men and 17 women with a mean age of 51 years (range: 15-77 years). The mean follow-up time was 6 months (330 months). No significant differences were found in the time to fracture healing, although the beginning with load walking was earlier in the nail group. Discussion: Currently there is no consensus on the therapeutic management of distal tibia fractures without joint extension. Conclusions: After analyzing the results, we consider that both intramedullary nail osteosynthesis and a locked plate are valid options in the treatment of fractures of the distal third of the tibia.(AU)
