Carpometacarpal interpositional spacer, non-bioabsorbable

A carpometacarpal interpositional spacer, non-bioabsorbable, is a device implanted into the first carpometacarpal joint to treat pain, instability, and motion disabilities in the thumb caused by arthritis. These spacers are typically spherical and made from durable materials like metal or ceramic to provide long-term support.

Such devices are generally regulated as medical implants and require appropriate regulatory clearance or approval before market availability. They are supplied as permanent implants and are not designed to be absorbed by the body over time.
