The Easyspine Posterior Spinal System is a posterior, non-cervical pedicle and non-pedicle system intended to provide immobilization and stabilization of spinal segments in skeletally-mature patients as an adjunct to fusion in the treatment of the following acute and chronic instabilities of the thoracic, lumbar and sacral spine:
* Degenerative disc disease (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies
* Spondylolisthesis
* Trauma (i.e., fracture or dislocation)
* Spinal stenosis
* Deformities or curvatures (i.e., scoliosis, kyphosis, and/or lordosis)
* Tumor
* Pseudloarthrosis
