What is it indicated for?

The CRESCENT™ Spinal System is indicated for interbody fusion with autogenous 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 1 spondylolishtesis 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. These devices are intended to be used with supplemental fixation

instrumentation which has been cleared by the FDA for use in the lumbar spine.

Indications for use as stated in the FDA summary.
