ABSTRACT

ABSTRACT Peri-articular giant cell tumours present a unique challenge to the orthopaedic surgeon due to their locally aggressive nature. Native joint-preserving options confer less morbidity in comparison to radical excision and reconstruction; however, recurrence rates tend to be higher. The use of polymethyl methacryllate (PMMA) decreases the recurrence rate, but it has potentially devastating effects on the articular cartilage. To safeguard against this, the use of an insulating layer between the PMMA and the articular cartilage may be utilized with the goal of protecting the latter and is referred to as the Sandwich technique.


RESUMEN Los tumores de células gigantes periarticulares representan un desafío único al cirujano ortopédico debido a su naturaleza localmente agresiva. Las opciones de conservación de las articulaciones nativas confieren menos morbilidad en comparación con la supresión y reconstrucción radicales. Sin embargo, las tasas de recurrencia tienden a ser más altas. El uso de polimetilmetacrilato (PMMA) disminuye la tasa de recurrencia, pero tiene efectos potencialmente devastadores sobre el cartílago articular. Para protegerlo, el uso de una capa aislante entre el PMMA y el cartílago articular puede ser utilizarse con el objetivo de proteger este último, lo que se conoce como la técnica del sándwich.
