Unlike the popularized DePuy ASR hip replacement products that have been widely criticized in relation to an all-metal design (metal for the ball and socket), the Stryker Rejuvenate and ABG II is made of plastics, ceramics and metal to mimic the natural hip movement. However, the ABG II neck-stem joint still uses metal-on-metal parts to secure the hip in place.
Most problems with the Stryker ABG II Modular Hip System are believed to derive from the metal-on-metal connection which has been associated with a series of problems including:
- Heavy metal poisoning
- Pseudo tumors
- Repeated dislocations
- Revisionary sugery
