TAICH Long Cemented Stem
Femoral Hip System
Product Overview
- Double-Tapered Straight Stem:
Optimized for cemented fixation, enhancing bone cement penetration into cancellous bone trabeculae to create multiple micro-locking mechanisms. - Anatomical Neck-Shaft Angle:
Features a 132° neck-shaft angle, specifically designed to better suit Chinese patients. - Adjustable Offset Design:
Allows for customization to accommodate varying patient anatomies and functional needs. - Precision Placement Guide:
A clear proximal implant guideline ensures accurate positioning and optimal bone cement thickness. - Distal Centralizer for Stability:
Blind-hole distal centralizer ensures proper alignment in the medullary cavity, enabling controlled prosthesis subsidence.
Special Description
The Threaded Hole is convenient to control rotation during implantation
132 degrees neck-shaft angle
Markings on the proximal stem is to assist positioning to restore exact leg length
High-polish surface
The high-polish surface can convert part of the shear force at the cement-implant interface into compressive stress perpendicular to the cement mantle.
Bone cement is highly resistant to compressive stresses from the prosthesis. When a mechanically compatible prosthesis generates compressive stress during implantation, it should not cause fractures or damage to the bone cement layer.
Long-term clinical follow-up has confirmed this.
The mirror-polished stem creates radial compressive loading to reduce shear force as stem migrates distally.
Distal centralizer prevents the tilt of the prosthesis in the medullary cavity and equalizes thickness of the cement mantle.
