Exeter stem
The Femoral Component of the Exeter Total Hip System
The first Exeter hip was implanted in November 1970 by Professor Robin Ling at the Princess Elizabeth Orthopaedic Hospital, Exeter UK. In 2003 66,000 Exeter stems were implanted in 41 countries worldwide. In Australia and New Zealand the Exeter stem is the most often
used stem for primary hip replacement.1 The continuing success of the Exeter Total Hip System is the result of lessons learned from more than 36 years of clinical experience, research and development. A published clinical series of 325 Exeter Universal hip replacements in patients from ages 24 to 87 years showed 100% stem survival at 8-12 years.2
Stem Design
The basic stem shape is a polished, double tapered and collarless design. This shape has remained unchanged since 1970 due to excellent long term clinical results.3 A very small number of modifications have been made to other aspects of the original stem design
Materials
The Exeter stem is made of Orthinox, a high grade stainless steel alloy. Orthinox provides superior mechanical strength combined with excellent corrosion resistance, which are critical properties required for orthopaedic implants. Modular Femoral Heads compatible for use with the Exeter stem are made of Orthinox (metal) or alumina ceramic (ceramic).
Bone Cement
Surgical Simplex® bone cement, with its superior strength and long clinical history, holds orthopaedic implants securely in place. The Exeter stem is designed to take advantage of Simplex® bone cement's inherent material characteristics.

Disclaimer
The implants described in this brochure are representative of Stryker hip replacement implants that your surgeon may choose to use in your hip replacement surgery. Notwithstanding your surgeon's pre-surgery evaluation of the hip replacement implants expected to be used for your surgery, it may be necessary, for clinical reasons, for your surgeon to make a revised assessment at the time of your operation. This may result in your surgeon deciding to use different implants (which may not necessarily be Stryker products) to meet your needs.
