The Premier is intended to provide immobilization of spinal segments in skeletally mature patients as an adjunct to fusion in the following acute and chronic instabilities or deformities of the thoracic, lumbar, and sacral spine (T1-S1): 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; curvatures (i.e., scoliosis, kyphosis, and/or lordosis); tumor; and failed previous fusion (pseudoarthrosis).

The purpose of this 510(k) is to make modifications to the previously cleared Premier Spinal System (K160320). The changes include modifications to the implants, surgical instruments, indications and labeling. The Premier consists of fixed-angle screws, fix-angle reduction screws, multi-axial screws, multi-axial reduction screws, rods, crosslink plates, set screws, planar screw, iliac screw, domino connector, lateral connector and hooks.

It is made of Titanium Alloy (Ti6Al4V), which meets ASTM F136-13, Standard Specification for Wrought Titanium-6 Aluminum-4 Vanadium (Extra Low Interstitial) Allov for Surgical Implant Applications, which are widely used for surgical implants with wellknown biocompatibility.

The proposed devices are provided non-sterile. It is required to be sterilized via autoclave method to reach a SAL of 106 by the hospital prior to surgery. The recommended sterilization method was validated per ISO 17665-1: 2006 Sterilization of health care products -- Moist heat -- Part 1: Requirements for the development, validation, and routine control of a sterilization process for medical devices.

The provided text does not describe an AI medical device or a study proving its acceptance criteria. Instead, it is an FDA 510(k) clearance letter for a Premier Thoracolumbosacral pedicle screw system, which is a physical orthopedic device used in spinal surgeries.

Therefore, I cannot extract the requested information about acceptance criteria, study details, sample sizes, expert qualifications, or ground truth related to an AI device. The document focuses on regulatory clearance for a medical implant and mentions conformance to ASTM standards and ISO guidelines for sterilization, not AI performance metrics.
