HEDJET™

HEDJET™'s Double Lead Screw features two thread leads running simultaneously along the screw body. The result: 2× faster insertion than single-lead screws — directly reducing operative time and intraoperative fluoroscopy exposure.

Paired with the proven DOVETAIL locking mechanism, HEDJET™ ensures consistent, high-torque screw-rod capture — maintaining construct integrity under the cyclic loading demands of the thoracolumbar spine.

Mono, poly-axial, reduction mono, reduction poly, cannulated mono, and cannulated poly screw options provide the full range of fixation strategies — from percutaneous MIS approaches to open deformity correction.

Screw diameters from 4.5mm to 9.5mm and lengths from 20mm to 120mm — the widest size range in the Medyssey posterior fixation lineup — ensuring optimal fit across all thoracolumbar levels and patient anatomies.

Straight 5.5mm rods from 80mm to 200mm and pre-bending 5.5mm rods in 80mm and 110mm lengths, available in both Titanium Alloy and Cobalt-Chrome Molybdenum Alloy for tailored construct stiffness.

All HEDJET™ implants are manufactured from Titanium Alloy (Ti-6Al-4V ELI) — the gold standard in spinal implant materials for its optimal combination of strength, biocompatibility, and MRI compatibility.
