Anatomic design to restore normal anatomy for optimal range of motion
- Tapered fixation plug pulls the implant against the resected bone surface
- Easy slide-lock mechanism with multiple insert thicknesses of 8, 9, 10, and 11 mm
- Matching articular geometry with talar implant allows for maximized contact area
- Ti plasma spray enhances long term fixation
- Tibial base size 0 now available
- 4 universal tibial base sizes for both left and right ankles
- 4 talar component sizes, wider anteriorly for better bone coverage
- Two distinct radii of curvature, medially and laterally, avoid overstressing the deltoid ligaments
- Based upon anatomy, the flexion/extension axis is the axis of a cone to allow normal external rotation of the foot during dorsiflexion
- Stability is provided by a hollow fixation plug and three bone cuts (anterior, posterior, lateral) to resurface the talus with minimal bone removal
Highly accurate and reproducible instrumentation
User friendly instrumentation and minimal steps
The Precision Instrumentation System was developed from the original Salto mobile-bearing design in order to restore the patient's normal anatomy and obtain an optimal primary fixation of the components. The instrument system allows for accurate component positioning with tibial and talar preparations that are separate but codependent.
Tibial Preparation:
A key principle is that the mobile-bearing concept has been moved from the implant to the instrumentation at the stage of the trial reduction. The trial tibial base, featuring a highly polished surface to remain mobile against the resected distal tibia, is allowed to rotate into proper position, thus self-aligning the prosthesis. After this optimal tibiotalar alignment is achieved, the preparation for the tibial keel and plug are completed.
Talar preparation:
The talar resections are linked to the tibia and allow for a measured resection with equal implant replacement.
The precise guides for the 3 talar resections allow for an anatomic resurfacing of the talus with immediate stability.
