Abstract
We report the clinical results for10 cases of periprosthetic fracture after Hip Arthroplasty between April 2005 and March 2009.
On the basis of the Vancouver system, 7 cases were classified as Type B1, 1 case as Type B2, and 1 case as Type C.
Type B1 cases were treated with a cable plate system, wiring only, locking compression plate and conservative treatment respectively. Type B2 cases were treated with revision arthroplasty or wiring. The type C case was treated with a plate. We evaluated the JOA score, bone union, the period until full weight- bearing, operation time, intraoperative blood loss and complications.
All fractures healed with complete union. The mean JOA score was 69.6 preoperatively and 56.0 postoperatively. The mean period for the callus formation was 6.8 weeks. The mean period until full weight bearing was 8.6 weeks. The mean operation time was 180 minutes,and the mean blood loss was 359 ml.
We considered that the locking compression plate is useful for Vancouver types B1 and Type C. A bone graft should be considered for Vancouver types B2 and 3.
