Division: Hip Reconstruction
Category: Hip Reconstruction

TRI-LOCK® was originally introduced in 1981 and was the first proximally coated tapered-wedge hip stem available to orthopaedic surgeons and their patients. With a well documented clinical history, TRI-LOCK demonstrated a 98% survivorship rate at 10 years for 68 patients.1


Features & Benefits

Features Benefits
GRIPTION® Porous Coating • Provides initial stability

• Allows for biological tissue ingrowth

• Helps provide consistent implant seating height
Reduced lateral shoulder, thin geometry and optimized length • Allow for bone preservation
Neck geometry • Improves range-of-motion and decreases the risk of dislocation due to neck impingement 2,3, 4

• Allows for hip stability

• Ability to achieve 178˚ range of motion when coupled with the PINNACLE® Acetabular Cup System during flexion/extension2

• Maintains a constant 130˚ neck angle allowing tissue tension to be increased without affecting leg length
Progressive dual offsets with direct lateralization • Ability to optimize soft tissue tension

• Ability to meet patients’ anatomic needs with availability in standard and high offsets
Broach-only technique and wide range of instrumentation • Accommodates surgeon preferences for traditional or less-invasive surgical approaches
Initial axial and rotational stability • Designed to limit micromotion at the implant to cortical bone interface making long term-fixation possible
Component sizing options in consistent intervals • Help achieve proper fit within the femur

•Ability to fine tune seating height and adjust leg length
