Alternative Anchors: Hooks and Sublaminar Wires ...

Specific fixation lamina hooks are specialized spinal implants used in posterior instrumentation, designed to engage the inferior (infralaminar) or superior (supralaminar) edge of the lamina to provide stability for spinal deformity correction, particularly in thoracic and lumbar procedures. They are often used as alternatives or supplements to pedicle screws for superior biomechanical strength in osteoporotic bone or to enhance rigidity, especially in revision cases or to reduce proximal junctional kyphosis.

Key Aspects of Lamina Hooks:

Types: Infralaminar hooks (up-going) hook under the lamina, while supralaminar hooks (down-going) hook over the top edge.
Fixation Function: Often used in "claw" constructs (pair of opposing hooks) to provide strong attachment to the spine, aiding in compression of a segment or graft.
Indications: Indicated for use where pedicles are small, to avoid using pedicle screws, and for stabilizing constructs at the cephalad or caudal ends of fusion, say NIH.
Application: Generally used in conjunction with rods and pedicle screw systems to enhance the stability of the fixation.

Site Preparation: Often requires partial resection of the spinous process or laminotomy (removing bone) for insertion, especially for supralaminar placement.
Instrumentation: Often used in combination with rods and screws for scoliosis or fracture correction, says ResearchGate.
Offset Option: Offset hooks can be utilized to align with pedicle screw tulips to provide a stable, consistent construct, according to ScienceDirect.com.
