Derived from a unique spherical bearing and clevis linkage combination, the Clevisphere Joint delivers a smooth, free motion ankle joint with a continuously variable posterior stop.

The Clevisphere Joint is made from participation-hardened stainless steel to achieve the durability that healthcare providers and patients expect from Tamarack ankle joints. The self-lubricating bearing needs no maintenance and the fabrication process is a breeze, thanks to the auto-aligning feature of the Clevisphere Joint, which doesn’t require a forming jig to fabricate.


Model 747 Clevisphere Ankle Joints are available in adult size only. Each kit includes a set of molding dummies.
