Fracture of Revision Modular Femoral Stem

Number of revision total hip arthroplasties (THA) has increased in past decade. Use of modular femoral components has followed this number because of advantage of adjustment and restoration of joint kinematics including leg lenght, femoral version and offset. Fracture of modular uncemented femoral component is rare complication after revision hip surgery. There are not many cases described in medical literature. Several factors can lead to this kind of prosthesis failure: increased BMI, high activity levels, undersized femoral component, varus stem orientation and poor proximal bone support shown by absence of the calcar. The aim of this paper is to show a case of modular tapered femoral prosthesis fracture and technical aspects of THA that may increase the risk of such complication.
