Device Classification

Product Code NKG Posterior Cervical Screw System
Device Class Class 2 - Special Controls
CFR Regulation 21 CFR 888.3075
Definition Posterior Cervical Screw Systems Are Intended For Use In Fusion Procedures Of The Cervical Spine And/or Craniocervical Junction And/or Cervicothoracic Junction For: 1) Spinal Fractures And Dislocations; 2) Deformities; 3) Instabilities; 4) Failed Previous Fusions; 5) Tumors; 6) Inflammatory Disorders; 7) Spinal Degeneration, 8) Facet Degeneration With Instability; And 9) Reconstruction Following Decompression To Treat Radiculopathy And/or Myelopathy. These Systems Are Also Intended To Stabilize The Spine In The Absence Of Fusion For A Limited Time Period In Patients With Tumors Involving The Cervical Spine In Whom Life Expectancy Is Of Insufficient Duration To Permit Achievement Of Fusion.
What this classification means

Class II devices require demonstration of substantial equivalence to a legally marketed predicate device. This pathway does not require clinical trials - it relies on engineering equivalence and performance data. Most Orthopedic devices follow this clearance model.
