Abstract
Eleven revision total hip arthroplasties were treated with proximal segmental femoral allograft reconstruction in which the diameter of the distal host bone was larger than the largest long-stem femoral component which could fit into the segmental allograft. A long, lateral step-cut osteotomy of the allograft was used with placement of the lateral cortical allograft inside the distal host bone. All allograft-host bone junctions healed. The average time to union was 6.7 months. The long step-cut osteotomy provides stability of the allograft-host bone junction when the diameter of the host bone is larger than the allograft. The osteotomy also provides a large surface area of contact between the allograft and host bone.
