Stem and Positioning System
The Comprehensive Fracture System was designed for complex fractures of the proximal humerus. It is also cleared for use in non-fracture cases and can be cemented or press-fit. The system is compatible with the humeral heads and glenoids of the Comprehensive and Bio-Modular Shoulder Systems.
Fracture Stem
- Reverse Morse taper for improved glenoid access
- Hashmarks aid proper reproduction of humeral height
- Lateral/medial fins with suture holes for optimal tuberosity fixation
- Engineered contour suture holes means significant reduction in suture wear1
- Reduced proximal body and 45 degree neck angle for easier tuberosity reconstruction
- Made from CoCr, which has a higher modulus of elasticity than titanium, allowing for less resistance to flexing within the humeral canal
- Material properties of CoCr provide for smaller stem sizes than titanium
Internal Positioning Sleeve
- Complete internal design eliminates need for external jig
- Internal design does not interfere with range of motion assessment
- Sleeve secures trials and final prosthesis at desired height
- Constructed of PMMA
