TalarLock™ Subtalar Arthroereisis System
Subtalar ArthroereisisThe TalarLock™ is a specialised arthroereisis implant designed to stabilise the subtalar joint and correct hyperpronation. By preventing the talus from shifting too far downward or backward, the device preserves natural joint movement while limiting the excessive inward rolling of the foot and its associated complications. It is supported by a dedicated set of single-use surgical instruments for precise delivery and placement.
