AJS -Hip Stem System
The AJS® hip stem system features a complete range of cementless and cemented implants for primary arthroplasty. Because they are shaped to very closely fit the proximal endosteal femoral geometry of European patients, the AJS® stem gives outstanding primary stability via an immediate tight fit. The lateral shoulder of the prosthesis fills the medullary cavity in a way that blood loss is minimised. The CCD-angle is 132°.
The cementless options have a 90µm thick hydoxyapatite (HA) coating proximally to encourage rapid secondary stability / biological fixation.
The cemented options have a matt finish on the internal fixation areas which defines (and helps to control) the insertion depth during definitive implantation.
