ABSTRACT
Objective To study treatment of Vancouver type-B periprosthetie femoral fractures after total hip arthroplasty.Methods There were 10 cases with Vancouver type-B periprosthetic femo- ral fractures after total hip arthroplasty being treatment,including three cases with type-B1 undergone open reduction and allografi strut to fix the fracture,two with type-B2 undergone open reduction and revi- sion with a long stem and five with type-B3 undergone open reduction,revision with a long stem and al- lograft strut to restore bone.The mean duration of follow-up was 27 months(8-36 months).The Harris Hip Score and radiographs were used to evaluate the outcome.Failure of the procedure.was defined as the need for revision surgery because nonunion of fracture,implant loosening,and infection.Results All cases obtained successful fracture healing,with no stem loosening or infection.Of all,nine cases were a- ble to walk by themselves but one needed aid in walking.The Harris Hip Score was 83 at the time of the final follow-up.Osseous union of the allograft to the host femur occurred in eight hips and mild graft re- sorption in two.The cotex thickness of host femur was increased more than 3-5 mm.Conclusions Stem stability and bone quality are important factors determining the outcome of treatment for periprosthet- ic femoral fracture after hip arthroplasty.Good outcome can be achieved by adopting different treatments according to sub-classification of Vancouver type-B fractures.The allograft strut for the treatment of a Vancouver type-B periprosthetic femoral fracture can not only provide fixation,but also make fracture heal fast and augment bone mass and strength.
