axIOLink® PCFD Tether System
Addressing the Primary Driver of Progressive Collapsing Foot Deformity
Product Overview
The axIOLink® PCFD Tether System is designed to address Progressive Collapsing Foot Deformity (PCFD) by reconstructing the Interosseous Talocalcaneal Ligament (ITCL)—the primary stabilizer of the subtalar joint and a key contributor to peritalar subluxation.1-4
Utilizing a minimally invasive soft-tissue reconstruction approach, the system enables surgeons to restore subtalar alignment while supporting concurrent spring ligament and deltoid ligament reconstruction procedures.
Why ITCL Reconstruction Matters
Peritalar Subluxation (Class D PCFD) is increasingly recognized as the primary pathomechanical driver of symptomatic PCFD.1-4 Attenuation of the Interosseous Talocalcaneal Ligament leads to loss of the talocalcaneal rotational tether, resulting in:
- Subtalar joint instability
- Hindfoot valgus progression
- Talocalcaneal divergence
- Sinus tarsi impingement
- Subfibular impingement
- Progressive collapse of the medial arch
The axIOLink® PCFD Tether System is designed to directly address this pathology through anatomic ITCL reconstruction and restoration of the subtalar joint center of rotation.
