ENGLEWOOD -- Paragon 28 announced it is adding an interference screw to its Grappler Interference Screw System.
Since its inception, Paragon 28 has obsessed over every aspect of foot and ankle surgery. Committed to creating tailored solutions to improve surgical outcomes, Paragon 28 has launched innovative products and instrumentation that help to streamline procedures, allow surgeons flexibility in technique and approach, and facilitate reproducible results benefiting both the surgeon and patient.
The Paragon 28 Grappler Interference Screw System was designed to provide surgeons an alternative fixation option for intraoperative tissue reattachment and fixation in the foot and ankle rounding out our comprehensive flatfoot portfolio.
The system includes 20 unique implants to accommodate varying patient anatomies and indications throughout.
Paragon said inherent challenges in addressing tendon transfers in the foot and ankle include:
- Varying anatomy and indications requiring a range of lengths and diameters
- Biocompatibility of implant
- Proximity of surrounding anatomy requiring accurate implant placement
- Achieving and maintaining appropriate tension of tendon in bone of varying densities
- Implant strippage due to torque transmission from driver
- Loss of tension following insertion of implant
The Grappler Interference Screw System was designed with these challenges in mind, the company said. The system includes seven diameters of implants with varying lengths to accommodate differing patient anatomies.
The implant is comprised of biocompatible PEEK material with inert properties and elasticity very similar to bone. The implant thread form is designed to minimize implant migration and loss of tension.
The instrumentation is offered as a non-sterile configuration, inclusive of all instrumentation needed for the procedure. Instrumentation was designed to streamline the procedure and minimize complications associated with tensioning and passing of suture.
Paragon said implant specific cannulated drills and tissue protectors are provided to help reduce imprecision when drilling, allowing for intended fit of implant and tendon. The tendon size, drill and implant diameters are one to one--there are no necessary calculations to be completed to determine drill diameter and implant size.
A novel trilobe driver engagement extends through the cannulation of the implant to help facilitate accurate implant insertion and help maximize torque transfer between driver and implant.
