Slack Motion Pedicle Couplings

• Many traditional rod system pedicle screws and attachments could be used with this progressively adjustable scoliosis rod system.

• Certain pedicle attachments to the scoliosis assembly could also be provided with fixed or adjustable slots or cam surfaces.

• Such slots can be tailored so as to allow them to become active later in the treatment protocol only after other desired corrections have reached a predetermined point.
