초록
The fully porous structure of the Lübeck prosthesis is designed to closely resemble cancellous bone. Several studies have reported ‘good’ to ‘excellent’ mid- to long-term results for use of the Lübeck, but stem fractures have been reported as a complication. We report on the case of an 85-year-old patient who underwent total hip arthroplasty (THA) using the Lübeck more than 25 years ago who underwent revision surgery for management of two periprosthetic femoral fractures and a stem fracture. A subtrochanteric fracture and a fracture of the stem were observed on radiographs, and a radiolucent line was observed in the proximal portion of the stem and a well-fixed distal portion was observed. Revision THA using a proximal femoral replacement stem and resection of the proximal femur has been proven as an effective procedure for treatment of an elderly patient with a fractured Lübeck stem with a well-fixed distal stem.
Abstract
The fully porous structure of the Lübeck prosthesis is designed to closely resemble cancellous bone. Several studies have reported ‘good’ to ‘excellent’ mid- to long-term results for use of the Lübeck, but stem fractures have been reported as a complication. We report on the case of an 85-year-old patient who underwent total hip arthroplasty (THA) using the Lübeck more than 25 years ago who underwent revision surgery for management of two periprosthetic femoral fractures and a stem fracture. A subtrochanteric fracture and a fracture of the stem were observed on radiographs, and a radiolucent line was observed in the proximal portion of the stem and a well-fixed distal portion was observed. Revision THA using a proximal femoral replacement stem and resection of the proximal femur has been proven as an effective procedure for treatment of an elderly patient with a fractured Lübeck stem with a well-fixed distal stem.
