Cement Filling of Contained Defects from Bone Tumor Resections

The management of bone defects of the extremities has important particularities. Patients prefer limited procedures when facing with complex reconstructions and each filling option has benefits and disadvantages. We aimed to present our short and long term results with small contained bone defects after tumoral resections filled with different types of cement. Over a period of five years we identified ten cases that were operated in our service and met the inclusion criteria: contained bony defects following intralesional or marginal tumoral resections of the lower limb (weight bearing extremity skeleton) with a minimum of one year of follow-up. The most important finding of our study is that polymethylmethacrylate cement filling of contained bony defects after tumoral resections is the only one that allowed for immediate postoperative weight bearing. In addition, the bone cement interface proved stable as far as two years after the surgery. The cases described can contribute to a greater understanding when searching for solutions targeted on filling contained bone defects after intralesional resections. Polymethylmethacrylate cement proves to be a validated, versatile and safe procedure but future perspectives already show good outcomes with new osteoinductive components.
