Study designRandomised controlled trial
Secondary study designRandomised controlled trial
Scientific title
Study objectives1. How is bone remodelled around the cemented femoral head of three different designs of hip: triple tapered collarless (C Stems), double tapered collarless stems (TPS) and collared stems (Stanmore)?
2. To what extent do each type tend to conserve bone stock?
Ethics approval(s)Not provided at time of registration
Health condition(s) or problem(s) studiedSurgery: Total hip replacement
InterventionPatients will be randomised to receive one of the three types of hip:
1. Triple tapered collarless (C Stems)
2. Double tapered collarless stems (TPS)
3. Collared stems (Stanmore)

Pre-surgery, blood will be analysed for vitamin D, parathyroidhormone, and bone profile assay will be performed. Dual X-ray absorptiometry (DEXA) will be done preoperatively than at 3-5 days post-op, and at 3, 6, 12 and 24 months post-op.
Intervention typeProcedure/Surgery
Primary outcome measure(s)

Is there any difference between the bone loss secondary to bone remodelling in each type of hip?
