Treatment of periprosthetic femoral fractures following total hip arthroplasty with femoral component revision.

摘要: Background: Revision total hip arthroplasty is indicated for most periprosthetic fractures that occur around the stem of femoral implant. The purpose present study was to assess results and complications revision treatment fractures. Methods: We evaluated 118 hips in 116 patients who underwent because an acute Vancouver type-B fracture. implant used a cemented forty-two hips, proximally porous-coated uncemented twenty-eight, extensively thirty, allograft-prosthesis composite or tumor prosthesis eighteen. mean duration follow-up 5.4 years. Results: Kaplan-Meier analysis demonstrated probability survival 90% at five years 79.2% ten with removal any reason as end point. Sixteen components were rerevised: rerevised loosening; three, loosening association fracture nonunion; two, recurrent dislocation; one, new Additionally, six implants resected deep infection (five) prosthetic (one). Radiographs ninety-six surviving showed twenty-one had evidence implant, four nonunion fracture, two both implant. Conclusions: successfully restored function patients. greatest long-term problems nonunion. Better seen when uncemented, used. Level Evidence: Therapeutic study, Level IV (case series [no, historical, control group]). See Instructions Authors complete description levels evidence.
