From Which Medical Device
The Tri-Lock Bone Preservation Stem is an uncemented tapered wedge design primary hip replacement stem. The original Tri-Lock was introduced in 1981 as the first proximally coated tapered-wedge hip stem available. Geometrical features which preserve bone include a reduced lateral shoulder and a thin antero-posterior profile.
The stem incorporates Gription fixation technology, and has a 12/14 Articuleze taper.
As of 2013, the stem has an unclassifed ODEP rating. Healy et al (2009) reported a 99.8% survivorship for the stem at 8.9 years.
