Resumen (ES)
We are describing 3 cases of femoral component
failure of a total hip arthroplasty with fully coated hidroxiapatite
(Furlong, JRI limited, London), without any traumatic
event. The follow-up before failure was 7 and 5 years. The
fracture of femoral stem was always just distal to the metaphisal
cone. The ingrowth of the distal portion of the femoral
component increased by hidrixiapatite causes abnormal
transmission of biomechanical forces in the metafiso-diafisal
union increasing the risk of material failure.
