Summary
Cervical total disc replacement (TDR) can lead to unexpected C-5 vertebral fractures, even in single-level procedures. Careful selection and placement of keel-design implants are crucial to prevent such complications.
Area of Science:
- Orthopedics
- Neurosurgery
- Spinal Surgery
Background:
- Degenerative disc disease is a common condition affecting the cervical spine.
- Cervical total disc replacement (TDR) is an established surgical treatment option.
- Keel-design prostheses are utilized in TDR procedures.
Observation:
- A 67-year-old male patient underwent single-level ProDisc-C TDR at C5-6.
- Postoperatively, the patient experienced immediate radicular pain relief and no neck pain.
- On postoperative Day 3, a radiograph revealed a vertical split fracture of the C-5 vertebra.
Findings:
- The C-5 vertebral fracture was managed conservatively.
- Two years postoperatively, CT scans showed stable device position and fracture fusion.
- The fracture did not result in neurological symptoms or device migration.
Implications:
- This case highlights a potential complication of cervical TDR with keel-design implants.
- Prudent selection and meticulous installation of these prostheses are recommended.
- Even in single-level TDR, careful surgical technique is essential to mitigate risks.

01:29Herniated Intervertebral Disc l: Introduction
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...
01:27Degenerative Disc Disease I: Introduction
Degenerative disc disease is a chronic condition in which intervertebral discs gradually lose structure and function. It is not infectious or autoimmune; rather, it results from age-related biochemical and mechanical changes, influenced by genetic, metabolic, and environmental factors.Structure and Function of DiscsThe spine contains 23 intervertebral discs that absorb load, distribute forces, maintain spacing, and allow flexibility. Each disc consists of a nucleus pulposus, a gel-like core...
01:23Degenerative Disc Disease ll: Pathophysiology
The symptoms of degenerative disc disease arise from a combination of mechanical compression, vascular compromise, and biochemical inflammation, which together disrupt nerve function and produce pain.Mechanical CompressionDisc degeneration reduces height and elasticity, predisposing to herniation of the nucleus pulposus, a major cause of radicular pain. Herniations may be protrusion (bulging with intact annulus), extrusion (nucleus extends beyond disc but remains connected), or sequestration...
