The Salto® Talaris Total Ankle Prosthesis is a new generation ankle replacement that mimics the anatomy and flexion/extension movement of the natural ankle joint, and is an alternative to traditional ankle fusion. ¹

Advancements in orthopaedic technology continue to revolutionize surgical options. Today's surgical instruments and implants make orthopaedic surgery more precise and more effective than ever before. One such advancement can now be seen in the Salto Talaris, which has been modeled after the human anatomy and is positioned to redefine the classic approach to ankle arthroplasty.

The innovative Salto Talaris now provides surgeons with the ability to reproduce the natural flexion/extension axis of the ankle with an anatomic design. The Salto Talaris implant design and instrumentation is founded on the Salto mobile-bearing ankle prosthesis, which has been in clinical use since 1997 and at 6.4 year mean follow-up (5-8.5) has a 93% survivorship.^1,2 The Salto Talaris provides accuracy and reproducibility with the Precision Instrumentation that has evolved to allow a fixed-bearing implant design and represents the philosophy "Less is Sometimes More".

Products

Resorbable Fixation
System Screw

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

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.
