Presentation about hip replacement. Do professional slides, only include (Main points) and (Pictures). Do NOT include any explanations in the slides, you can do so in the comments on each slides.
Use the following notes and source.
FIRST : Cement Fixation
1. Cement is a viscoelastic polymer (pictures)
a. High compressive strength and low tensile strength
b. Tensile stresses stress-relax rapidly thus preventing fatigue failure
2. Exeter from Stryker (pictures)
a. Highly polished reducing friction between cement and implant
b. Design helps produce radial compressive loading that does not fatigue cement
SECOND : Biological fixation
1. The preferred implant in younger and more active patients
2. Rough, porous surface for bone ingrowth and stability
3. Secur-Fit Max from Stryker
a. Abrasion resistant Titanium coating
b. Spray hydroxyapatite on surface to promote bone ingrowth
4. Highly porous metal
a. Trabecular Metal - reticulated vitreous carbon with vapor deposition of tantalum (pictures)
b. High ductility and low modulus elasticity similar to trabecular bone
c. Cup is highly porous so extra screws can be put in to enhance stability (picutres)
