The RIPLEY SPINAL SCREW SYSTEM BY SAGICO is intended for use in the non-cervical spine. When used for anterior/anterolateral and posterior, non-cervical pedicle and non-pedicle fixation system, the RIPLEY SPINAL SCREW SYSTEM BY SAGICO is intended to provide additional support during fusion using autograft or allograft in Skeletally mature patients in the treatment of the following acute and chronic instabilities or deformities:
- Degenerative disc disease (DDD) (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;
- Curvatures (i.e. scoliosis, kyphosis, and/or lordosis);
- Tumor;
- Pseudoarthrosis; and
- Failed previous fusion
When used for posterior non-cervical pedicle screw fixation in pediatric patients, the RIPLEY SPINAL SCREW SYSTEM BY SAGICO implants are indicated as an adjunct to fusion to treat adolescent idiopathic scoliosis.
The RIPLEY SPINAL SCREW SYSTEM BY SAGICO for pediatric use is intended to be used with autograft and/or allograft. Pediatric pedicle screw fixation is limited to a posterior approach.
Indications for use as stated in the FDA summary.
