To evaluate the possible cause & describe, the transient, increased tracer uptake on SPECT- CT observed around the cementless femoral component in a proportion of patients who underwent primary hip arthroplasty using the Corail®Total hip system, in the absence of radiographic findings on serial follow up.

We evaluated various modalities used for hip imaging (radiographic, cross-sectional and scintigraphic) of patients who underwent Primary hip arthroplasty using the Corail®Total hip system from 2008 to date in at tertiary referral centre for primary and revision hip replacement surgery. Patients with painful arthroplasty were further evaluated with a thorough history, physical examination, blood analysis, plain radiographs and hybrid imaging (SPECT-CT). Correlation between the radiographic and scintigraphic findings on serial imaging was scrutinised. Patients who had symptoms in our cohort (since 2008) were all called...

339 patients underwent primary hip arthroplasty in our institution using the Corail® Total hip system between 2008 and 2016; of which: 31 patients (9.14%) had bone scans (28 had symptoms, 3 had scans for other reasons including two patients with total knee replacement with possible infection or loosening and one patient to investigate malignancy (was negative). Out of three asymptomatic patients 1 had increased uptake around the Corail® implant (incidence 1 in 339, 0.29%) within 1 year from surgery. Out of 28 patients with hip...

The concept of an extensive hydroxyapatite (HA) coating for the fixation of a specifically tapered femoral stem (Corail®) was introduced 25years ago. The aim was to achieve durable biological fixation while preserving normal periprosthetic bone activity. The value of uncemented fixation using HA-coated implants is widely accepted amongst scholars. The Corail® system offers validated superior osteointegration around the femoral stem when compared to other systems, partially due to the lack of medullary reaming required prior to placement of the femoral stem component. On histological evaluation,...
