RESUMO
The aseptic loosening of the femoral stem may require different treatments due to the complex problems related to the bone resorption (qualitatively and quantitatively): a minimum bone stock loss may result in a periprosthetic resorption that is so severe to make the fixation of the revision prosthesis extremely difficult. The revision surgery of a loosened hip prosthesis is often characterized by a complex reconstruction due to such severe loss of femoral bone tissue. We illustrate our experience with MP-Link modular stem (Waldemar Link, Hamburg, Germany) in cases of severe bone loss of the metaphyseal area and of the proximal third of the femoral shaft, assessing the technological developments (materials and design) over the years and examining the pros and cons of cementless distalfixation modular stems versus the traditional Wagner's stem.
