Femoral reconstruction with massive allograft and cementless prosthesis.

Classification of loss of bone substance in cases of prosthetic loosening allow for planning of the most suitable type of reconstructive surgery. The use of cemented prostheses has revealed negative long-term results. For this reason a cementless implant which is entirely coated is preferred in order to allow for distal anchoring (particularly in type 2B and 2C loosening). In more severe cases cancellous or cortical bone grafts stabilized by wiring will be used.
