Tarsus Screw System

Product Overview

The Tarsus Screw System is an implantable stabilization solution designed for the treatment of talotarsal instability (TTI) associated with excessive foot pronation. The implant is positioned within the sinus tarsi to stabilize the talotarsal mechanism, helping maintain proper alignment between the talus and calcaneus while preserving physiological joint motion.

The system consists of a range of implant sizes and dedicated instrumentation to facilitate accurate implant placement and reproducible surgical outcomes.

  • Optimized anatomical profile
  • Fit to a wide range of anatomies
  • Facilitated anatomical reduction

The System consists of 2 types of plates with Different variants of length

  • curved version
  • standard version
  • Improved fixation in the intramedullary canal
  • Angular rotation stability
  • Facilitated insertion into the intramedullary canal
  • Stable fixation of in the metatarsal head
  • Avoided collisions with articular surface
  • Enhanced plate and fixation stability
  • Specially designed for easy surgery
  • Dedicated targeter, raspator and other devices
  • Cortical and AV-Wiselock screws gives multiple strength in the implants.
  • Configuration for individual cases

Product Features

  • Designed to stabilize the talotarsal mechanism and address excessive foot pronation 
  • Maintains alignment of the talus and calcaneus while allowing normal talotarsal joint motion 
  • Improved screw thread design for enhanced resistance to pull-out forces 
  • Optimized implant geometry for stable sinus tarsi fixation 
  • New screw head design engineered to lock securely with the driver through the positioning sleeve 
  • Dedicated instrumentation for controlled implant insertion and positioning 
  • Available in sizes 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, and 12mm to accommodate varying patient anatomies
