Summary
Brief summary (as posted)
This study aims to evaluate the osseointegration of 3D printed porous collars in hip and knee resection prostheses, in order to eliminate one of the causes of diaphyseal osteolysis, which often lead to loosening of the implants, and therefore to guarantee a further improvement in fixation of the implants in terms of both primary and secondary stability.

Inclusion Criteria: * age \> 18 years at the time of surgery. * patients undergoing hip and knee resection prosthesis surgery with the use of collars porous 3D printed. * date of intervention: starting from the regular entry into use of 3D printed porous collars at the reference center. * Patients operated on for primary tumor outcomes. * Patients operated on for infection. * Patients operated for revisions with severe loss of bone substance. * Patients capable of giving informed consent and obtaining written informed consent (prospective part/patients in follow-up). Exclusion Criteria: * Patients lost to follow-up and/or for whom radiographic and clinical documentation is not available corresponding to the post-operative moment and the clinical follow-up visit (6 months and 1 years).
