Fracture of Revision Modular Femoral Stem
ثبت نشده
چکیده
The number of revision total hip arthroplasties is predicted to more than double in USA over the next 25 years from an estimated 40800 in 2005 to approximately 96700 in 2030 [1]. Modular femoral stems offer the advantage of adjustment and restoration of joint kinematics including leg length, femoral version and offset, regardless of the exact position of the distal part of the stem [2]. Disadvantage of modularity are complications such as fretting corrosion and fatigue failure on the modular junctions.

Periprosthetic femoral fractures treated with a modular distally cemented stem.
PURPOSE To assess the treatment outcome of revision hip arthroplasty for Vancouver type B3 periprosthetic femoral fractures using a modular distally cemented stem. METHODS 22 men and 14 women (37 hips) aged 66 to 79 (mean, 70) years underwent revision hip arthroplasty for Vancouver type B3 periprosthetic femoral fractures. The indication for surgery was periprosthetic fracture with stem loose...
متن کاملRevision total hip arthroplasty in patients with extensive proximal femoral bone loss using a fluted tapered modular femoral component.
Revision total hip arthroplasty (THA) is challenging when there is severe loss of bone in the proximal femur. The purpose of this study was to evaluate the clinical and radiographic outcomes of revision THA in patients with severe proximal femoral bone loss treated with a fluted, tapered, modular femoral component. Between January 1998 and December 2004, 92 revision THAs were performed in 92 pa...
متن کاملFracture of cementless femoral stems at the mid-stem junction in modular revision hip arthroplasty systems.
BACKGROUND Mechanical failure of femoral stems at the modular junction of revision hip arthroplasty systems has been reported only infrequently. In the current study, the cause of six stem fractures, which occurred in vivo, was analyzed with use of clinical data and failure analysis. METHODS Six patients with a fracture at the mid-stem junction of a modular revision hip implant were identifie...
متن کاملModular tapered titanium stems in revision arthroplasty of the hip: The Risk and Causes of Stem Fracture.
Tapered fluted titanium stems are increasingly used for femoral revision arthroplasty. They are available in modular and non-modular forms. Modularity has advantages when the bone loss is severe, the proximal femur is mis shapen or the surgeon is unfamiliar with the implant, but it introduces the risk of fracture of the stem at the junction between it and the proximal body segment. For that rea...
متن کاملManaging femoral bone loss in revision total hip replacement: fluted tapered modular stems.
If a surgeon is faced with altered lesser trochanter anatomy when revising the femoral component in revision total hip replacement, a peri-prosthetic fracture, or Paprosky type IIIb or type IV femoral bone loss, a modular tapered stem offers the advantages of accurately controlling femoral version and length. The splines of the taper allow rotational control, and improve the fit in femoral cana...
