ABSTRACT

Fifteen cases of periprosthetic femoral fractures of after total hip arthroplasty (THA) in Department of Orthopedic Surgery, Guangdong People’s Hospital between May 1997 and May 2007 were retrospectively analyzed. According to the classification of Vancouver, there was 1 case of type AG, one of type AL, 3 of type B1, 5 of type B2, 3 of type B2, and 2 of type C. Two cases of type A were treated with conventional method, and cases of type B1 and C were treated with open reduction and internal fixation. Cases of type B2 and B3 were treated with a long-stem cemented prosthesis revision plus allograft cortical strut bone. Through 3-12 months follow-up, all the fractures were healed, and bone allografting was successful, but with high rate of complications which were curable. The new prosthesis stem was fixed well. Excellent and good rate of Harris scores for hip joint was 73.3%. Therapy selection based on Vancouver classification for periprosthetic femoral fracture after total hip arthroplasty is an effective method.
