ABSTRACT
Objective To evaluate the clinical results of uncemented fully porous-coated long femoral stems in treating Vancouver type B2 periprosthetic femoral fracture following hip arthroplasty.Methods A retrospective analysis was made on 12 patients (12 hips) with Vancouver type B2 periprosthetic femoral fracture treated using the uncemented fully porous-coated long femoral stem prosthesis combined with cerclage fixation with steal-wire or titanium cable devices from February 2006 to January 2013.There were 5 males and 7 females,aged average 69.8 years (range,62 to 79 years).The status of primary arthroplasty was uncemented bipolar hemiarthroplasty in 2 patients and total hip arthroplasty in 10 patients (2 cement and 8 cementless femoral stems).At the final follow-up,Harris hip score for clinical evaluation,Beals and Tower's criteria for radiological evaluation,and complications were recorded.Results There were no intra-operative complications such as femoral perforation and femoral fracture.All patients were followed up for mean 38 months (range,24-72 months).At the last followup,mean Harris hip score was 87.2 points (range,50 to 100 points).All fractures healed at average 16 weeks (range,12-28 weeks).All the 12 hips showed prosthesis stability despite there was one femoral stem subsidence of 3 mm.One patient slipped and sustained another periprosthetic fracture (Vancouver type B1) at postoperative 4 months and was treated successfully with locking plate and cables.According to the Beals and Tower's criteria,there were 10 excellent,1 good and 1 poor results.Final follow-up revealed no complications of deep vein thrombosis,dislocation and prosthesis loosening.Conclusion Uncemented fully porous-coated long femoral stems provide good primary stability that promotes fracture healing and offers a reasonable treatment of Vancouver B2 femoral periprosthetic fracture.
