[Complication in replacement of unconventional tumor prosthesis].

Abstract

Bone metastases from a primary cancer of any part of the body are the most common form of malignant bone tumor constituting approximately 70% of them. The proximal femur being the most common extra-vertebral location for its location; 10% of patients have some pathological fracture, which is a serious complication. Currently the objectives of the treatment of a pathological fracture are: resection with adequate oncological margins, that the patient survives the surgical intervention, maintain the functionality, that the placed implant has a longer life time than the patient. The use of non-conventional hip prostheses is an excellent treatment option fulfilling the 4 established objectives, therefore this case is presented in which a right bipolar hip hemiarthroplasty is performed with a non-conventional prosthesis where it was treated with a described complication and the surgery of resolution.
