It has been suggested that cemented fixation of total hip arthroplasty
(THA) is associated with an increased peri-operative mortality compared
with cementless THA. Our aim was to investigate this through a nationwide
matched cohort study adjusting for age, comorbidity, and socioeconomic
background. A total of 178 784 patients with osteoarthritis who underwent
either cemented or cementless THA from the Swedish Hip Arthroplasty
Register were matched with 862 294 controls from the general population.
Information about the causes of death, comorbidities, and socioeconomic
background was obtained. Mortality within the first 90 days after
the operation was the primary outcome measure.Aims
Patients and Methods
Large-head metal-on-metal (MoM) total hip replacements
(THR) have given rise to concern. Comparative studies of small-head
MoM THRs over a longer follow-up period are lacking. Our objective
was to compare the incidence of complications such as infection,
dislocation, revision, adverse local tissue reactions, mortality
and radiological and clinical outcomes in small-head (28 mm) MoM
and ceramic-on-polyethylene (CoP) THRs up to 12 years post-operatively. A prospective cohort study included 3341 THRs in 2714 patients.
The mean age was 69.1 years (range 24 to 98) and 1848 (55.3%) were
performed in women, with a mean follow-up of 115 months (18 to 201).
There were 883 MoM and 2458 CoP bearings. Crude incidence rates
(cases/1000 person-years) were: infection 1.3 In conclusion, we found similar results for small-head MoM and
CoP bearings up to ten years post-operatively, but after ten years
MoM THRs had a higher risk of all-cause revision. Furthermore, the
presence of an adverse response to metal debris seen in the small-head
MOM group at revision is a cause for concern. Cite this article:
Between 1999 and 2001, 90 patients underwent
total hip replacement using the same uncemented acetabular and femoral
components with a 28 mm metallic femoral head but with prospective
randomisation of the acetabular liner to either Durasul highly cross-linked
polyethylene or nitrogen-sterilised Sulene polyethylene. We assessed
83 patients at a minimum follow-up of ten years. Linear penetration
of the femoral head was estimated at six weeks, six and 12 months
and annually thereafter, using the Dorr method, given the non-spherical
shape of the acetabular component. There was no loosening of any component; only one hip in the
Sulene group showed proximal femoral osteolysis. The mean penetration
of the femoral head at six weeks was 0.08 mm (0.02 to 0.15) for
the Durasul group and 0.16 mm (0.05 to 0.28) for the Sulene group
(p = 0.001). The mean yearly linear penetration was 64.8% lower
for the Durasul group at 0.05 mm/year ( Cite this article:
