Type II IVDD is characterized by which process?

Type II IVDD is characterized by which process?

• A. Insidious bulging of annulus fibrosus
• B. Acute rupture of annulus fibrosus
• C. Fibrocartilaginous embolism
• D. Dwarfism

Answer: (A)

Type II IVDD is a chronic, degenerative disc disease where the annulus fibrosus thickens and the disc gradually bulges into the spinal canal. This produces a slow, insidious onset of signs rather than an abrupt event, which is why insidious bulging of the annulus fibrosus is the best description. In contrast, an acute rupture of the annulus fibrosus describes Type I IVDD, typically seen as a sudden extrusion of nucleus pulposus. Fibrocartilaginous embolism is a vascular spinal cord injury, not a disc protrusion issue, and dwarfism is not a process of IVDD.
