ABSTRACT
Two staged bilateral total hip replacement (THR) is commonly performed for bilateral hip end stage arthritis and is preferred as THR is a complex planned surgery and performing both sides simultaneously may be fraught with risks and complications. However, many studies now indicate that in carefully selected patients , single stage or simultaneous bilateral THR can be performed with successful and cost effective results. We report a case of one-stage bilateral THR performed in a 22 year old with bilateral severe arthritis due to ankylosing spondylitis. Patient was severely disabled due to pain and was only ambulating on wheelchair. After a successful single stage bilateral THR, patient recovered fully and after 6 weeks was walking independently without any pain, with full function of both hips and performing his occupation normally. The surgical costs to the patient and hospital were both economical. We conclude that single stage bilateral THR is a better surgical option for young and fit patients with bilateral hip arthritis.
ABSTRACT
Introducción: El reemplazo total de cadera bilateral en un tiempo genera controversia en la bibliografía. Quienes están a favor argumentan que se reducen los tiempos quirúrgicos y anestésicos, la estadía hospitalaria, la rehabilitación y los costos económicos. Quienes se oponen aducen que está asociado a mayor índice de complicaciones, como trombosis venosa profunda, tromboembolia pulmonar, osificaciones heterotópicas y resultados funcionales subóptimos. Materiales y métodos: Se realizaron 40 reemplazos totales de cadera bilaterales en un tiempo, en 20 pacientes: 16 varones (80 por ciento) y 4 (20 por ciento) mujeres, con un promedio de edad de 56 años y un seguimiento promedio de 25 meses; el ASA promedio fue de 2. Se utilizaron prótesis no cementadas e híbridas. Resultados: Todos los pacientes se encontraron satisfechos con los resultados en el último control. El hip score promedio fue de 90,4 puntos. El tiempo de cirugía promedio fue de 186 minutos, requiriendo 27 minutos menos para los reemplazos no cementados. Todos los pacientes deambularon a las 72 horas de la operación y 17 pacientes debieron recibir transfusiones. El seguimiento promedio fue de 25 meses (rango 8 a 72 meses). Conclusiones: El reemplazo total de cadera bilateral en un tiempo, en la presente serie, mostró ser un procedimiento seguro. Depende de una adecuada selección del paciente, del correcto estudio de sus comorbilidades, además de la posición en decúbito dorsal y la utilización de prótesis no cementadas. Mostró disminuir los costos económicos y obtener una recuperación funcional más rápida que los realizados en dos tiempos, sin aumentar los índices de complicaciones.
Background: The literature on bilateral simultaneous total hip replacement (BTHR) is controversial. Those who agree with the procedure, contend that it reduces the amount of anesthetic, surgical time and hospital stay, the rehabilitation is faster and economic costs are lower. Opponents argue that it is associated with a higher rate of complications, such as deep vein thrombosis, pulmonary embolism, and heterotopic ossification leading to subop-timal functional outcomes.Methods: 40 BTHR were performed in 20 patients. 16 males (80%) and 4 (20%) females, average age: 56 years, and average follow up: 25 months, the average ASA was 2. Uncemented and hybrid prostheses were used. Results: All patients were satisfied with the results at the last control. The average Hip Score was 90.4 points. The average surgery time was 186 minutes for hybrid replacements, requiring 27 minutes less for uncemented implants. All patients walked at 72 hs POP, and 17 required blood transfusions. The median follow-up was 25 months (range: 8-72 months). Conclusions: In our series the BTHR proved to be a safe procedure after an appropriate patient selection, the correct study of their co-morbidities, supine position for surgery, and cementless prosthesis. The economic costs were reduced, and the functional recovery was faster than in the two-stage bilateral THR, without increasing the complication rate.
