    Abstract:
    OBJECTIVE: To analyze the therapeutic effect of plate cable system and cortical strut bone graft in the prosthesis revision of the total hip arthroplasty for the treatment of Vancouver type B1 periprosthetic femoral fracture. METHODS: A total of 8 patients were selected from January 2006 to January 2013, including 6 males and 2 females, aged from 56 to 74 years old (62.52 years old on average). All the cases were treated by the long plate cable system and appropriate cortical strut bone graft. Harris score was used to evaluate the hip functions before and after the operation. Prosthesis stability and the bony union were assessed by the digital radiography. RESULTS: All the patients were followed up for 45 months on average ranging from 24 to 60 months after operation. All the fractures reached union, and there was no infection, stem loosening, nonunion and malunion. The Harris score was 28.45±5.78 before operation, which was improved to 83.46±10.21 after operation. X ray showed that the prosthesis was stable, and the host bone and bone graft achieved bony union in 7 patients;and the other 1 patient need further operation of revision around the loose stem. CONCLUSIONS: The prosthesis revision of the total hip arthroplasty with the locking plate and cortical strut bone graft used for the Vancouver type B1 periprosthetic proximal femur fractures has the advantages of simple manipulation, less complications, good recovery of the hip function and can improve bone quality to provide favorable conditions for operation of revision.
