Summary
Cervical disc arthroplasty complications like migration and subsidence occur early to mid-term, while pain and ossification appear later. Most revisions convert to fusion, with Mobi-C showing fewer fusion conversions.
Area of Science:
- Spine surgery
- Orthopedic surgery
- Biomedical engineering
Background:
- Cervical disc arthroplasty (CDA) is a motion-preserving alternative to anterior cervical discectomy and fusion for degenerative cervical disc disease.
- CDA procedure rates have increased by 654% in the last decade.
- CDA complications can necessitate repeat procedures or conversion to fusion.
Purpose of the Study:
- Evaluate the timing of cervical disc arthroplasty complications (early, intermediate, late).
- Analyze the progression of complications leading to revision surgeries.
Main Methods:
- Retrospective review of the FDA MAUDE database (2005-2023) for 9 CDA devices.
- Complications categorized by postoperative onset: early (<6 months), intermediate (6-18 months), late (>18 months).
- Revision types classified as repeat CDA or conversion to fusion.
Main Results:
- 688 revision cases reviewed; 265 reported onset time (median 12 months).
- Migration was the most frequent early and intermediate complication.
- Neck pain and heterotopic ossification (HO) were most common in the late phase.
Conclusions:
- CDA complication timing varies, with migration early/intermediate and pain/HO late.
- Most devices commonly convert to fusion upon revision.
- Data aids clinicians in patient monitoring post-CDA.

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...
01:23Degenerative 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...
