One of the uncemented cup systems used at our hospital is Pinnacle acetabular cup system. I thought I will collect more information about this system. Post below contains some of the links and useful information about this system

This system is developed and marketed by Depuy Orthopaedics, Allegedly useds Variable Interface Prosthesis (VIP) taper technology (cant find this patent application yet in either google patents or us patents database). Though some patents mention name “Pinnacle acetabular cup”

Quote from company website

DEPUY introduces the PINNACLE Acetabular Cup System with patented Variable Interface Prosthesis (VIP) taper technology. The PINNACLE Acetabular Cup is designed to accommodate multiple advanced bearing materials and provide surgical options without compromise. Surgeons now have a choice between standard polyethylene, MARATHON Cross-linked Polyethylene and ULTAMET metal inserts, which all work within one acetabular shell.

The Furlong H-A.C. Supravit® Coated Femoral Stem is based on the biomechanical teaching of Pauwels and has three distinct sections providing separate functions to satisfy the stressing requirements at different locations in the femur. The distal portion prevents toggle and because it is cylindrical will not allow axial distal loading.

Today I have seen  total hip replacement useing Mathys RM Classic cup with exeter stem. This cup is quite interesting because it is polyethelene cup which is inserted using uncemented technique. It has surface coating of pure titanium (one which we used). Reading company website they also have cup with hydroxy appetite coating. Outcome is quite good (96.7% at 15 yrs according to company)

Types of cups available

• Full profile cup
• Bevelled cup
• Bevelled metal-metal (metamys) cup
• Revision cup
