## Indications for use
The STALIF TT™, STALIF MIDLINE®, MIDLINE II™, and MIDLINE II-Ti™ is indicated for use with bone graft (autograft bone and/or allogenic bone graft composed of cancellous and/or corticocancellous bone graft) in patients with degenerative disc disease (DDD) at one or two contiguous levels from L2 to S1. These DDD patients may also have up to Grade I Spondylolisthesis or retrolisthesis at the involved levels. DDD is defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies. These patients should be skeletally mature and have had six months of non-operative treatment. Patients with previous non-fusion spinal surgery at the treated level may be treated. These implants may be implanted via a laparoscopic or an open anterior approach. The STALIF TT™, STALIF MIDLINE®, MIDLINE II™, and MIDLINE II-Ti™ is a stand-alone system intended to be used with the bone screws provided and requires no additional supplementary fixation systems. The STALIF TT™, STALIF MIDLINE®, MIDLINE II™, and MIDLINE II-Ti™ system must be used with autograft and/or allogenic bone graft composed of cancellous and/or corticocancellous bone graft.
