Introduction

The curettage of benign bone injuries or the development of metaphyseal fractures leads to the formation of bone defects, all of which must be filled with bone substitutes. Poly (methyl methacrylate) (PMMA) is the most widely used substitute in such cases, however, there has been some loosening of the cement for many years, which is related to the occurrence of osteoarthropathy.

A promising alternative to conventional PMMA is porous PMMA cement because porosity reduces the risk of necrosis and allows for osseointegration, while also having elasticity compatible with bone trabeculae.
