Pain in the well-fixed, aseptic titanium hip replacement. The role of corrosion.
Pain in the well-fixed, aseptic titanium hip replacement. The role of corrosion.
J Bone Joint Surg Br. 2004 Jan;86(1):27-30
Authors: Hallam P, Haddad F, Cobb J
We have investigated nine patients with cemented Furlong (JRI, London, UK) titanium hip replacements who presented with early pain despite a well-fixed, aseptic prosthesis. All were followed up clinically and radiologically at regular intervals. Pain was located in the thigh and was worse at night. Radiographs showed cortical hypertrophy of the femur around the tip of the stem. Eight of the nine patients subsequently required single-stage revision using an uncemented prosthesis, which relieved the pain. At revision, the pH of the tip of the stem was found to be highly acidic with macroscopic evidence of corrosion consisting of multiple layers of titanium oxides when studied by X-ray dispersive analysis. Cemented titanium implants have a potential for crevice corrosion leading to cortical hypertrophy and intractable pain.

The femoral cement mantle in three total hip replacements.
The femoral cement mantle in three total hip replacements.
Int Orthop. 2004 Feb;28(1):40-3
Authors: Mellor SJ, Ripley LG, Ricketts DM
We measured the size and volume of the femoral broaches and stems supplied with three commercial total hip replacement (THR) systems (JRI Furlong, Biomet Stanmore, and Howmedica Exeter). Using an in vitro method, we created cement mantles that could be directly measured. The broaches supplied with the Biomet Stanmore and the Howmedica Exeter systems allowed the creation of significantly thicker cement mantles than the JRI broaches and stems (Stanmore mean thickness = 1.7 mm, defects at 3% of measurement sites; Exeter mean thickness = 2.0 mm, no defects; JRI mantles mean thickness = 0.9 mm, cement defects at 29% of measurement sites). We conclude that, in vivo, the broaches supplied with the Stanmore and Exeter systems are significantly larger than the corresponding stems, and will excavate a cavity large enough to accommodate the appropriate femoral stem surrounded by an intact cement mantle.

J Bone Joint Surg Br. 2000 Apr;82(3):378-82

We describe the clinical and radiological outcome of 100 consecutive total hip replacements in 86 patients using the JRI Furlong hydroxyapatite-coated femoral component. The follow-up was 100% at a mean of ten years (9.0 to 12.0). All 54 living patients (62 hips) were examined annually. Their mean Merle d'Aubigné score was 5.8/5.6/4.6. A total of 32 patients had died. Their notes at the last annual assessment recorded a similar outcome to that of the living patients. Radiographs showed no radiolucent lines around any femoral component and there were no signs of impending failure. One patient required excision arthroplasty, but the femoral component had been bonded satisfactorily. There have been no other revisions of femoral components. Our findings suggest that the hydroxyapatite coating gives a satisfactory prosthesis-bone interface which is preferable to any other system.
