Introduction
•Start of Cemented Hips
•Cement Bone Disease
•Younger Patients, higher expectations
•Biologic Bond
Cheap
Forgiving
Even in osteoporotic bones
Longer Follow-up
Easier to revise
Biological
No interface between Implant
& Bone
Quicker
Extra Interface
Cementing Techniques
More time
Reaction to Cement
Expensive
Chances of Fracture
Not for every bone
•Are all cemented the same ?
•Are all uncemented the same ??
•Hybrid
•Reverse hybrid
•Which one is better ?
•Is there a clear answer ?
•Why ???
•Individual studies
•Conflicting evidence
•Effect of age ?
•One size fits All ??
•Registries –conclusive proof for it?

Age Distribution of Hip Arthroplasty Procedures,
2012-2018 (N=597,258)
Femoral Stem Fixation for Elective Primary Total Hip
Arthroplasty for Patients ≥65 Years of Age with Primary
Osteoarthritis and an Endpoint of Revision, 2012-2018
Femoral Stem Fixation for Elective Primary Total Hip
Arthroplasty for Males ≥65 Years of Age with Primary
Osteoarthritis and an Endpoint of Revision, 2012-2018
Femoral Stem Fixation for Elective Primary Total Hip Arthroplasty for
Females ≥65 Years of Age with Primary Osteoarthritis and an
Endpoint of Revision, 2012-2018
Cemented Fixation have better long term survivorship
Cemented fixation had better survival in older patients
Cementlessfixation had better survival in younger patients
Periprosthetic fractures were common in cementlessfixation
summary
•There seems to be shift towards uncemented THA especially in the
younger patients
•Cemented tends to do relatively better in older patient group
•Not all prosthesis are the same .
•Different Cemented /uncemented THA will have different results
