FEMORAL STRUT ALLOGRAFTS IN CEMENTLESS REVISION TOTAL HIP-ARTHROPLASTY

One hundred thirteen cases of cementless femoral revision total hip ar throplasty using either cortical strut or proximal calcar allografts w ere reviewed for radiographic incorporation at an average 4.75 years a fter operation. All cortical strut grafts were used to supplement the host bone after achieving stable femoral fixation by a tight distal di aphyseal fit. Eighty-seven of the 95 cortical strut grafts showed radi ographic evidence of graft incorporation. Eleven of the 18 calcar graf ts had resorbed. Complications consisted of eight dislocations, three pulmonary embolisms, two superficial infections, two myocardial infarc tions, and two sciatic nerve palsies. When stable distal fixation of c ementless femoral prostheses have been achieved, the cortical strut al lograft can be readily incorporated into the host femur and augments t he host bone structure.
