RESUMO

INTRODUCTION: Hip resurfacing arthroplastys are a valid alternative for the treatment of degenerative hip disorders in young adults. Poor results and adverse soft tissue effects have been reported with high levels of chromium and cobalt, limiting its indications. Objective is to analyze clinical and functional survival results of the Durom system 10 years after its implementation in a public hospital. The hypothesis is that better results and survival are obtained in patients selected according to FDA criteria. MATERIAL AND METHODS: Retrospective cohort study of 83 patients, 91 hips in 76 men and 7 women operated between 2005 and 2013 with Durom-type prostheses. Demographic study, diagnosis, BMI, radiological study, serum chromium cobalt levels, functional assessment according to MPD and HSS, complications and survival at 10 years of follow-up. A cohort of active men under 65 years of age and heads over 48mm is selected. RESULTS: Follow-up time of 121 months with a range from 84 to 176 months. With a mean age of 52.78 years, with 4 deaths and loss of follow-up of 3 cases. There are 12 complications that require reoperation (14.45%) with 2 chronic infections, 4 femoral neck fractures, 4 acetabular loosening and 2 cases of pseudotumors. With an overall survival of 85.4% (71-91.9) and 87.85% (85.5-91.1) in the absence of infection. No statistical relationship between complications and neck narrowing and the angles of inclination of the components. In selected patients, 69 men and 73 hips, we obtained an overall survival of 91.82% and excluding infection of 93.18% at 10 years. CONCLUSIONS: The indication of the Durom system in the treatment of degenerative processes in selected active young patients presents better results and survival at 10 years, although somewhat lower than other highly indicated veneering models.

RESUMO

Introducción: Las prótesis de recubrimiento son una alternativa válida para el tratamiento de los trastornos degenerativos de cadera del adulto joven, pero han sido reportados malos resultados y efectos adversos en partes blandas con niveles altos de cromo y cobalto, limitándose sus indicaciones. Nuestro objetivo es analizar resultados clínicos, funcionales y de supervivencia del modelo Durom a los 10 años de su implantación en un hospital público. La hipótesis es que se obtienen mejores resultados y supervivencia en pacientes seleccionados según criterios de la FDA. Material y métodos: Estudio retrospectivo de cohortes con 83 pacientes, 91 caderas en 76 hombres y 7 mujeres operados entre 2005 y 2013 con prótesis tipo Durom. Estudio demográfico, diagnóstico, IMC, radiológico con posición de implantes, estrechamiento del cuello y tipo de unión ósea, niveles de cromo y cobalto en suero, valoración funcional según MPD y HSS, complicaciones y supervivencia a los 10 años de seguimiento. Se selecciona una cohorte de varones activos menores de 65 años y cabezas superiores a 48mm para la misma valoración. Resultados: El tiempo de seguimiento fue de 121 meses, con un rango de 84 a 176 meses. Con una edad media de 52,78 años, con 4 defunciones y pérdida de seguimiento de 3 casos. Se producen 12 complicaciones que precisan reintervención (14,45%) con 2 infecciones crónicas, 4 fracturas del cuello femoral, 4 aflojamientos acetabulares y 2 casos de pseudotumores. La supervivencia global fue del 85,4% (71-91,9), y del 87,85% (85,5-91,1) en ausencia de infección a los 10 años. No hubo relación estadística entre las complicaciones y el estrechamiento de cuello y los ángulos de inclinación de los componentes. En pacientes seleccionados, en 69 hombres y 73 caderas obtenemos una supervivencia global del 91,82% y, excluyendo la infección, del 93,18% a los 10 años.(AU)

RESUMO

El hundimiento protésico es una de las potenciales complicaciones de los vástagos femorales de anclaje diafisario no cementado en las cirugías de revisión protésica, lo cual puede afectar a la estabilidad y a la osteointegración del componente. En este estudio retrospectivo evaluamos los resultados al año y a los 5 años (especialmente el hundimiento y la relevancia clínica) de 40 revisiones de vástago femoral consecutivas, comparando 2 vástagos de revisión modulares no cementados rectos vs. curvos, con 20 pacientes en cada grupo. No se observó ningún fracaso mecánico y se obtuvo una mejoría en cuanto a resultados funcionales en la totalidad de los casos. El hundimiento radiológico medio fue de 9,9±4,9mm (p=0,076); 14 pacientes (35%) tuvieron ≥10mm de hundimiento, con un máximo de 22mm en un caso. Nuestros resultados son similares a las series publicadas en la literatura, sin manifestaciones clínicas a corto-medio plazo ni incremento del número de complicaciones o aflojamiento del vástago en ninguno de los 2 grupos. No se observaron diferencias en cuanto al hundimiento protésico al año y a los 5 años posteriores a la cirugía entre los 2 tipos de vástagos (AU)


Subsidence is one of the potential complications in femoral stem revision total hip arthroplasty surgery, and can affect stability and osseointegration. A retrospective study was conducted on the outcomes at one year and 5 years (specifically subsidence and clinical relevance) of 40 consecutive femoral total hip arthroplasty revisions, comparing two modular cementless revision stems, Straight vs. Curved, with 20 patients in each group. No mechanical failure was observed, and there was an improvement in functional outcomes. Mean radiological subsidence was 9.9±4.9mm (straight=10.75mm vs. curved=9.03mm), with no statistically significant difference between groups (p=0,076). Fourteen patients (35%) had ≥10mm of subsidence, up to a maximum of 22mm. The subsidence found in this study is similar to published series, with no short-term clinical manifestations, or an increased number of complications or stem loosening in either the Straight or Curved group. No differences in subsidence were observed at one year and 5 years after surgery between the 2 types of stems (AU)

RESUMO

Subsidence is one of the potential complications in femoral stem revision total hip arthroplasty surgery, and can affect stability and osseointegration. A retrospective study was conducted on the outcomes at one year and 5 years (specifically subsidence and clinical relevance) of 40 consecutive femoral total hip arthroplasty revisions, comparing two modular cementless revision stems, Straight vs. Curved, with 20 patients in each group. No mechanical failure was observed, and there was an improvement in functional outcomes. Mean radiological subsidence was 9.9±4.9mm (straight=10.75mm vs. curved=9.03mm), with no statistically significant difference between groups (p=0,076). Fourteen patients (35%) had ≥10mm of subsidence, up to a maximum of 22mm. The subsidence found in this study is similar to published series, with no short-term clinical manifestations, or an increased number of complications or stem loosening in either the Straight or Curved group. No differences in subsidence were observed at one year and 5 years after surgery between the 2 types of stems.

RESUMO

Objetivo. Estudio comparativo del ángulo de inclinación acetabular en la colocación del cotilo mediante cirugía asistida por ordenador y por el sistema convencional. Material y método. Estudio retrospectivo comparativo entre 42 pacientes a los que se les implantó una prótesis total de cadera. En un grupo de 21 pacientes se utilizó un sistema de navegación quirúrgica para la colocación del acetábulo y en otro, también de 21 pacientes, la técnica estándar con alineación manual. Sobre una imagen radiológica y sobre una tomografía computarizada (TAC) se midió el ángulo de inclinación acetabular de ambos grupos. Resultados. En el grupo con navegador la inclinación media medida intraoperatoriamente con el sistema de navegación fue de 44,14° (desviación estándar [DE] 1,35). Según la radiología convencional, de 44,57° (DE 1,88), y según la TAC, 44,81 (DE 2,06), diferencias que no fueron significativas. En el grupo de cirugía convencional, aunque los valores medios de inclinación no difieren con respecto al grupo con navegador, la dispersión obtenida fue significativamente mayor (p = 0,005). No se observó un aumento significativo ni del tiempo quirúrgico ni tampoco de las complicaciones postoperatorias. Conclusiones. La utilización de un sistema de navegación para la implantación acetabular en cirugía de cadera disminuye el índice de dispersión y favorece la colocación del implante en una posición más cercana a la ideal


Aim. To carry out a comparative study of the acetabular inclination angle when a prosthetic cup is put in place using computer-assisted surgery and when it is implanted by means of conventional surgery. Materials and methods. This was a comparative, retrospective study of 42 patients that underwent total hip replacement (THR). In a group of 21 patients a surgical navigation system was used to determine the placement of the acetabular prosthesis and in another group, also made up of 21 patients, the standard technique of manual alignment of the prosthesis was used. Using X-rays and CAT scans the acetabular inclination angle was measured in both groups. Results. In the group in which a navigator was used the average angle measured intraoperatively was 44.14° (standard deviation [SD] 1.35). Measured using conventional X-rays it was 44.57° (SD 1.88) and measured with a CAT scan it was 44.81° (SD 2.06). These differences were not significant. In the group that underwent conventional surgery, though the average inclination angle values did not differ with reference to the group operated with the use of a navigator, the dispersion seen was significantly greater (p=0.005). No significant increase was seen in OR time nor in postoperative complications. Conclusions. The use of a navigation system to implant an acetabular prosthesis in hip surgery decreases the scatter index and makes it possible to place the implant in a position closer to the ideal one
