Hypermobilty Cervical Model demonstrating an unstable C3-4. Constructed from a degenerated specimen with a recreation of the intervertebral discs, ligamentum flava and the cruciform ligament at C1-2 this model shows how an adjacent level (C3-4) to the most degenerated segment (C4-5) is unstable and hypermobile in end ranges of motion. Further features include a C6-7 disc central protrusion as well as a herniating red nucleus under compressive and flexion loads. Custom creation.
