The OSSIOfiber® Compression Staple is indicated for fixation of arthrodesis, osteotomies and fractures in hand or foot surgery in the presence of appropriate brace and/or immobilization in adults and children (2-12 years) and adolescents (12-21 years) in which growth plates have fused or in which growth plates will not be crossed by fixation. The number and size of the OSSIOfiber® Compression Staples must be adapted to the indication.

The OSSIOfiber® Compression Staple is a fixation implant made of degradable poly (L-lactide-co-D, Llactide) (PLDLA) reinforced with continuous mineral fibers. The polymer content degrades by hydrolysis into alpha-hydroxy acids that are metabolized by the fibers are made from minerals that are found in natural bone. As the OSSIOfiber® implants degrade, the load transfers to the surrounding anatomy throughout the healing period of the osteotomy, fusion, or fracture. Substantial degradation takes place within approximately 18 months as shown in pre-clinical studies, thus eliminating the requirement for future hardware removal surgery. The OSSIOfiber® Compression Staples are supplied sterile, for single patient use only. They are available in several sizes: 9-25 mm bridge lengths, and 10-22 mm leg lengths. The OSSIOfiber® Compression Staples are designed to be used with commonly available orthopedic surgical tools such as ISO 9714 compatible instrumentations.

The provided text is a 510(k) summary for a medical device (OSSIOfiber® Compression Staple) and does not describe a study involving an AI/Machine Learning device or a diagnostic algorithm. It is a submission for a physical orthopedic implant seeking to expand its indications for use to include pediatric patients, based on substantial equivalence to previously cleared devices.

Therefore, I cannot extract the information requested regarding acceptance criteria, device performance, sample sizes, expert ground truth, MRMC studies, or standalone algorithm performance, as these concepts are not relevant to this type of device submission.

The document discusses:

• Device: OSSIOfiber® Compression Staple (an orthopedic implant)
• Purpose of Submission: To add pediatric patient populations (children 2-12 years and adolescents 12-21 years) to the indications for use.
• Basis for Clearance: Substantial equivalence to previously cleared predicate devices (K212594, K233302) and an additional predicate (K210582), as well as reference devices (K231272).
• Non-Clinical Data: Biocompatibility was established in prior clearances and referenced from other devices. No additional mechanical performance testing was deemed necessary because the expanded indication did not present a "new worst case" compared to already cleared predicates.

In summary, the information requested is not present in the provided text because the device and its submission type do not involve an AI/ML component or diagnostic testing that would require such performance evaluation metrics.
