Brief summary
The primary objective of this prospective, post-market study is to collect data to assess the long term outcome of a broad contact modular interbody device in the form of the InterFuse S™ or InterFuse T™ device in patients undergoing long construct fusion for degenerative disc disease and/or scoliosis. Comparisons will be made with published historical data..
Detailed description
The primary objective of this prospective, post-market study is to collect data to assess the long term outcome of a broad contact modular interbody device in the form of the InterFuse S™ or InterFuse T™ device in patients undergoing long construct fusion for degenerative disc disease and/or scoliosis. While there is no concurrent control population, there is ample historical control data to be used for comparison. The study will include up to two hundred (200) patients, up to 10 centers, and provide a prospective evaluation of the InterFuse T and/or InterFuse S Interbody Fusion System. Primary endpoints will be assessed at twelve months post-surgery. All patients enrolled in the study will be followed for at least 24 months.

Inclusion criteria
* 1\. The patients has a planned fusion construct of at least five levels and will have the InterFuse (S) or (T) planned for L5-S1 and/or L4-L5. 2\. The patient has documented conservative (non-operative) treatment for at least 6 months. 3\. The patient has a VAS score of ≥ 60 mm for Back and/or Leg. 4. The patient has an ODI ≥ 40%. 5.
