Open-Door Laminoplasty System includes a Grade-3 pure titanium plate and Ti6Al4V screws, specially designed for multilevel posterior cervical decompression surgeries.
It preserves cervical lordosis, reduces axial neck pain, and promotes early rehabilitation post-operatively by maintaining canal expansion with secure fixation.
Laminoplasty: also known as canal expansion surgery, is a procedure in which one or both sides of the lamina are surgically cut and hinged backward and laterally to enlarge the spinal canal, thereby achieving decompression. Cervical laminoplasty is a surgical technique designed to decompress the cervical spinal cord.
OPLL: Ossification of the posterior longitudinal ligament (OPLL) refers to the pathological process in which the posterior longitudinal ligament of the cervical spine undergoes hyperplasia, thickening, and ectopic ossification, eventually leading to spinal canal stenosis and spinal cord compression.
This condition results in a series of clinical symptoms and signs associated with myelopathy.
OPLL is particularly common in Asian populations and was first discovered and reported in Japan.
● Anatomical Plate Design – Pre-bent titanium plates with rounded edges and polished low-profile surface minimize soft tissue irritation.
● Variable Open-Width Options – Plates available in 6–18 mm widths (in 2 mm increments) to match patient anatomy.
● Integrated Fixation Supports –Lamina-support arms and hinge extensions ensure stable purchase in varied laminar thicknesses and depths.
● 20° Conical Locking Holes – Guarantee strong angular stability when used with matching screws.
● Self-Tapping Screws –Designed for precise, efficient insertion, complemented by colored anodized surfaces for enhanced durability.
● Stable Channel Maintenance – Provides rigid, long-term laminar opening, reducing canal reclosure risk.
● Early Mobilization Encouraged – Secure fixation allows for immediate movement post operation, potentially lowering axial pain rates.
● Protects Spinal Alignment – Preserves cervical lordosis while achieving reliable decompression.
● Custom Fit for Each Patient – Multiple sizes and anatomical supports facilitate personalized stabilization and surgeon flexibility.
