Revision THR after periprosthetic femoral fractures. An analysis of 23 cases.

23 consecutive proximal femoral fractures in 22 patients, who had previously undergone total hip arthroplasty, were treated with long revision stems. At the time of the fracture, 21 stems were loose. An uncemented Wagner revision stem was used in 9 cases and different conventional revision stems in the others. All fractures healed, but 7 of the conventional revision implants rapidly loosened again, whereas so far none of the Wagner stems have loosened.
