The Single Lock Hooks are components of a spinal fixation system used primarily in the thoracic and lumbar spine to anchor the fixation construct to the posterior elements of the vertebra (lamina or pedicle). Unlike screws, hooks are used to grasp or “hook” under bony structures. The “Single Lock” mechanism refers to the method by which the spinal rod is secured to the hook head. This system includes various specialized hooks to address different anatomical requirements and surgical goals.
Key features include:
-
Modular System: Includes five distinct hook types for different surgical anchor points.
-
Primary Use: Posterior spinal fixation, providing anchor points for rods in complex spinal deformity corrections or trauma stabilization.
-
Pedicle Hook (Code No. 807): Designed to anchor onto the pedicle of the vertebra.
-
Laminar Hooks (Code No. 808, 809, 811, 817): Designed to anchor beneath the lamina, available in different blade configurations (Reduced Distance, Angle Blade, Narrow Blade, Wide Blade).
-
Locking Mechanism: Features a “Single Lock” system to secure the spinal rod.
-
Material: Implied Titanium (common for spinal implants).
