Comparisons were also done for the hip and lumbar regions calculated by DXA
scans. Hip regions were Femoral Neck (FN), Trochanter, Bone Mineral Content
(BMC/grams) and Bone Mineral Density (BMD/grams/cm 2 ) analysis for these
regions. Lumbar region analysis were on L1-L4.
Results showed there were statistical differences in most areas measured in the hip
except for NSA. FNAL= 15.7mm for blacks and 20.10mm for whites. HAL was
65.80mm for blacks and 73.76mm for whites.
Bone density of the femur showed an Area of 40.63cm 2 and 46.20cm 2 and BMC
of 39.94grams and 42.71grams black and white respectively. The value of BMC to
Area in the blacks achieves equality in BMD with the whites 0.962 to 0.924.
Bone density values for the lumbar were not significantly different: Blacks 0.9408
grams/cm 2 and whites 0.9523grams/cm 2 .

Abstract title: One- or two-stage revision of infected hip replacements: is a
randomised controlled trial possible?
1. Purpose of study.
Many patients with prosthetic hip infection receive revision surgery. Following
prosthesis removal and debridement, prostheses are replaced in the same operation
(one-stage) or delayed (two-stage). As the implications for patients and healthcare
providers are substantial, we assessed the feasibility of a randomised controlled trial
(RCT) to guide optimum treatment.
2. Description of methods.
We examined the National Joint Registry for England and Wales for use of one- and
two-stage revision and variation between centres.
In qualitative studies we interviewed 19 patients treated for prosthetic hip infection
and 12 specialist surgeons to assess acceptability of randomisation.
As there are no RCTs, we systematically searched bibliographic databases for case
series of infection treated with one- or two-stage revision. Further infection rates were
combined in random effects meta-analysis.
