Hydroxyapatite Coating

The coating of implant's stem with Hydroxyapatite (HA) leads in human body to a solid bond with the bone. Besides being biocompatible (compatible with living systems), Hydroxyapatite is bioactive, in the sense that it demonstrates a surface chemical activity which supports bone ingrowth. HA is a naturally occurring mineral, comprised of calcium and phosphorus and found in vertebrate bone and teeth.

PureFix™ HA is Stryker Orthopaedics’ own brand of Hydroxyapatite coating and one of the first Hydroxyapatite coating to enter the US Market more than 12 years ago. It is manufactured using a proprietary and technologically advanced in-house process providing the strictest control over HA coating parameters.
