Clinical Experience of the First 20 Prestige LP Cervical Arthroplasties

Cervical Disc Replacement with Prestige LP Cervical Disc Replacement

An Alternative to Anterior Cervical Discectomy and Fusion (ACDF)

 

Indications:

Cervical Spondylotic Radiculopathy and or Myelopathy

Average 1.5 year follow up:

20 Prestige LP cervical disc arthroplasties

 

Analysis of Results:

Scoring

Biomechanics

Radiological Analysis

Subsidence and maintenance of decompression

Motion Preservation

Heterotopic Ossification

Analysis of Complications

 

Adjacent Segment Disease Literature- controversial still?

Hilibrand et al.:

2.9% patients each year with ACDF require additional surgery due to adjacent level problems

25% prevalence of new symptomatic disease at a level adjacent to a prior fusion within 10 years.
