Qualitative and quantitative retrieval analysis of a ball-and-socket cervical disc replacement
The findings of the present study, specifically the minimal bony ongrowth, lack of extraction damage, and radiographic imaging, indicated that most devices were removed due to migration. Metrology analysis revealed a depression on the posterior edge of the inferior endplate polyethylene ball, which correlated with anterior slippage. This may be a distinctive feature of the PCM's relatively large ball-and-socket design that led to increased stress during extension, causing anterior migration.
