    ObjectiveTo discuss the treatment and clinical result of using titanium cerclage band to teat intra- and post-operative femoral fracture in total hip arthroplasty.MethodsFrom August 1999 to September 2007, twenty-two patients who suffered from intra-and post-operative femoral oblique fracture in total hip arthroplasty were reviewed among 2186 consecutive total hip arthroplasty patients performed by one surgeon. There were 12 fractures occurred intraoperative and 10 fractures postoperative. There are 9 primary and 13 revision total hip arthroplasty patients including 10 men and 12 women. All fractures are classified as Vancouver B1 type in 15 cases and B2 type in 7 cases. Two to five titanium cerclage bands had been used to fix the fracture followed by open reduction with 13 cases using 2 cerclage bands and 7 cases using 3 bands and 1 case using 4 bands and 1 case using 5 bands. Whether change the original stem or not depended on the classification of fractures and stability of stems. There were 15 cases of type B1 and 1 case of type B2 without changing stems and 6 cases of type B2 changing to revision stems of the same series of original stems.ResultsAll fractures showed successfully union for 12 - 20 weeks (average 18 weeks) after operation. The average Harris score of the hip improved to 90 points (80 to 95 points) at an average 6.5 years follow-up (4 to 11 years) and the average range of motion of the hip got to 120° (105° - 135°). Femoral prostheses were well-fixed without any subsidence or lucent lines or loosening. All patients were satisfied with the results with well-fixed and good alignment of femoral stem.ConclusionsStrong fixation of the fractures and good initial stability of femoral stem can be obtained using titanium cerclage bands to fix the intra- and post-operative femoral oblique fracture. Original stems should be changed to revision stems in case of type B2 and be retained in case of type B1.
