Extract

There is a variety of reconstructive options for revision of a femoral component in the setting of loss of proximal bone stock. Techniques employing stems designed to be inserted with16,28,31,33 and without8,18,27 cement have demonstrated durable results on intermediate to long-term follow-up; the use of a bulk allograft1,4,34 and replacement of the proximal aspect of the femur have been advocated for patients who have a massive loss of bone stock24. This paper will focus on the clinical results of a newer technique in which allograft cancellous bone is impacted into the proximal aspect of the femoral canal to provide a so-called neo-endosteum for a component inserted with cement.
