Femoral canal occlusion in total hip replacement using a resorbable and flexible cement restrictor.
We have investigated the use of a conically-shaped cement plug made of Polyactive (PA), a biodegradable copolymer. The flexibility and hydrogel properties were thought to facilitate occlusion of the femoral canal even when it was oval or irregular in shape. The function of the plug was first compared with that of the Thackray polyethylene model in 16 artificial plastic femora. The maximum intra...
متن کاملVertebroplasty--high viscosity cement versus low viscosity cement.
The patients with intensive pain caused by the vertebra body fracture were treated by application of low viscosity cement (LVC), (Vertebroplastic, DePuy) and high viscosity cement (HVC), (Confidence, DePuy,) into the body, by means of diascopy through unilateral transpendicular approach. Application of LVC was made in 75 patients, on 109 vertebrae, and HVC was applied in 12 patients on 14 verte...
متن کاملRevision of the cemented femoral stem using a cement-in-cement technique: a five- to 15-year review.
The removal of well-fixed bone cement from the femoral canal during revision of a total hip replacement (THR) can be difficult and risks the loss of excessive bone stock and perforation or fracture of the femoral shaft. Retaining the cement mantle is attractive, yet the technique of cement-in-cement revision is not widely practised. We have used this procedure at our hospital since 1989. The st...
متن کاملThe fixation of the cemented femoral component. Effects of stem stiffness, cement thickness and roughness of the cement-bone surface.
After cemented total hip arthroplasty (THA) there may be failure at either the cement-stem or the cement-bone interface. This results from the occurrence of abnormally high shear and compressive stresses within the cement and excessive relative micromovement. We therefore evaluated micromovement and stress at the cement-bone and cement-stem interfaces for a titanium and a chromium-cobalt stem. ...
متن کاملCement migration after THR. A comparison of charnley elite and exeter femoral stems using RSA.
Studies using roentgen stereophotogrammetric analysis (RSA) have shown that the femoral components of cemented total hip replacements (THR) migrate distally relative to the bone, but it is not clear whether this occurs at the cement-implant or the cement-bone interface or within the cement mantle. Our aim was to determine where this migration occurred, since this has important implications for ...
