Proximally coated uncemented stem. Suitable for cobalt chrome heads and ceramic.
Straightforward instrumentation and easy to insert. Lack of distal coating means some possibility of subsidence but revision if needed will generally be easier with lower need for ETO. Wedge shape of distal end does carry some risk of splitting the femur if not broached and prepared carefully. Also there are reports of squeaking when the stem is used with ceramic bearings, theoretically postulated to be due to vibration of the uncoated distal part of the stem within the femoral canal.
Survivorship is largely similar to most other mainstream uncemented prostheses and there have not been any major issues with trunnionosis to the best of my knowledge.

This is my preferred uncemented femoral stem.
Choice of offset for increased stability.

After cemented stems, it is a joy to put in an Accolade. Haven't had issues with subsidence of thigh pain with a small personal series. However, they do have a higher revision rate than an Exeter in the NJR series, so there is a trade off.
