When used as a nonpedicle, noncervical posterior system, the ORIA Spinal Clip System is indicated for: (1) degenerative disc disease (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies); (2) spondylolisthesis; (3) fracture; (4) spinal stenosis; (5) deformities (i.e., scoliosis, kyphosis, lordosis), (5) tumor, (6) pseudarthrosis, (7) tumor resection, and/or (8) failed previous fusion.

ORIA Spinal Clip System is indicated for skeletally mature patients: (1) having severe spondylolisthesis (Grades 3 and 4) at L5-S1 joint; (2) who are receiving fusions using autogenous bone graft only; (3) who are having the device fixed or attached to the lumbar and sacral spine (L3 and below); and (4) who are having the device removed after the development of solid fusion mass.

When used as a pedicle screw system in the non-cervical spine of skeletally mature patients, the ORIA Spinal Clip System is indicated for immobilization and stabilization of spinal segments as an adjunct to fusion in the treatment of the following acute and chronic instabilities or deformities of the thoracic, lumbar, and sacral spine: (1) degenerative spondylolisthesis with objective evidence of neurological impairment, (2) fracture, (3) dislocation, (4) scoliosis, (5) kyphosis, (6) spinal tumor, and (7) failed previous fusion (pseudarthrosis).

The ORIA Spinal Clip System includes components that fit together to form a construct for use during spinal fusion surgery. The system contains components of various designs and sizes that allow the surgeon to build an implant system for each of four defined indications and to fit the patient's anatomical and physiological requirements. The components include: Lumbar, thoracic, and pedicular hooks: Sacral screws: Pedicle screws: Set screws; Locking nuts; Rods in various lengths; Connectors with set screws (sacral, transverse, lateral); Connecting elements; Instruments and Sterilizer trays.

The provided text is a 510(k) summary for the ORIA Spinal Clip System. It details the device's intended use, materials, and substantial equivalence to previously cleared devices. However, this document does not contain any information about acceptance criteria, device performance studies, sample sizes, ground truth establishment, or expert reviews as requested in the prompt.

Therefore, I cannot fulfill your request for the specific details about acceptance criteria and the study proving the device meets them based only on the provided text.

The document focuses solely on establishing substantial equivalence for regulatory clearance, which typically relies on comparisons to predicate devices and adherence to relevant standards, rather than new multi-reader comparative effectiveness studies or detailed performance metrics.
