The I-Hip™ system features femoral stem and acetabular cup porous coated components, cross-linked polyethylene liners and Co-Cr alloy femoral heads.
Recognized femoral stem design with progressive features offer surgical adaptability
- Narrowed femoral neck designed to allow increased range of motion before impingement
- Shortened femoral stem lengths (i.e., 15-20% less than historic designs with this geometry type) to accommodate various surgical approaches
Fully coated hemispherical cup designed for biologic fixation
- Familiar 180-degree hemispherical, forged Ti-6Al-4V alloy cups
- 2-hole cups to provide option for adjunct fixation with cancellous bone screws
Modular femoral heads to facilitate functional versatility with various intraoperative bearing options
- Cobalt chrome femoral head available in 28mm, 32mm, and 36mm diameters to assist with ensuring adequate fit and stability
- Femoral heads provided in 5 different offset lengths (i.e., -4mm, 0mm, +4mm, +8mm, +12mm) to restore proper biomechanics and leg length
Modernized tapered wedge femoral stem design used more than 30 years
- Designed for axial stability by creating cortical bone contact both at the medial and lateral endosteal cortices
- Comprehensive offering of offsets in femoral stem and femoral head designs
Historically utilized poly liner locking mechanism with over 20 years of use
- Cup-to-head ratio designed to gain the largest size femoral head within a given cup without sacrificing bearing thickness
- Cup provided with integrated locking ring for intraoperative securing and removal of poly liners
Large diameter head (36mm) promote increased stability
- For an identically placed cup and stem, a larger head provides increased range of motion before impingement and reduces the risk of dislocation
- Clinical studies show that large diameter heads (i.e., 32mm and greater) can be used to reduce the rate of dislocation.
