Regulatory Classification

Identification

Single/multiple component metallic bone fixation appliances and accessories are devices intended to be implanted consisting of one or more metallic components and their metallic fasteners. The devices contain a plate, a nail/plate combination, or a blade/plate combination that are made of alloys, such as cobalt-chromium-molybdenum, stainless steel, and titanium, that are intended to be held in position with fasteners, such as screws and nails, or bolts, nuts, and washers. These devices are used for fixation of fractures of the proximal or distal end of long bones, such as intracapsular, intertrochanteric, intercervical, supracondylar, or condylar fractures of the femur; for fusion of a joint; or for surgical procedures that involve cutting a bone. The devices may be implanted or attached through the skin so that a pulling force (traction) may be applied to the skeletal system.

## Purpose of Submission
This traditional 510(k) premarket notification is being submitted to obtain clearance for the OSSIOfiber® Interference Screw.

## Device Description
The OSSIOfiber® Interference Screw is an orthopedic implant made of poly (L-lactide-co-D,L-lactide) (PLDLA) reinforced with continuous mineral fibers. The OSSIOfiber® Interference Screws are cannulated and fully threaded, available in diameters ranging from 6 to 12 mm and lengths from 23 to 28 mm. The polymer content degrades by hydrolysis into alpha-hydroxy acids that are metabolized by the body. 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 implantation site. 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® Interference Screw is supplied sterile, for single patient use only.

The OSSIOfiber® Interference Screw is designed to be used with commonly available orthopedic surgical tools such as ISO 9714 compatible instrumentation such as ISO 9714 compatible instrumentations.

## Indications For Use

The OSSIOfiber® Interference Screws, are indicated for fixation of tissue, including ligament or tendon to bone, or a bone/tendon to bone 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. Interference fixation is appropriate for surgeries of the knee, shoulder, elbow, ankle, foot, and hand/wrist where the sizes offered are patient appropriate; Specifically:

- Shoulder: Rotator Cuff Repairs, Bankart Repair, SLAP Lesion Repair, Biceps Tenodesis, Acromio-Clavicular Separation Repair, Deltoid Repair, Capsular Shift or Capsulolabral Reconstruction
- Foot/Ankle: Lateral Stabilization, Medial Stabilization, Achilles Tendon Repair, Hallux Valgus Reconstruction, Midfoot Reconstruction, Metatarsal Ligament Repair, Flexor Hallucis Longus for Achilles Tendon reconstruction, tendon transfers in the foot and ankle
- Knee: Repair/Reconstruction of the Anterior Cruciate Ligament, Posterior Cruciate Ligament, Medial Collateral Ligament, Lateral Collateral Ligament, Patellar Tendon, Posterior Oblique Ligament, Iliotibial Band Tenodesis, MPFL

- Hand/Wrist: Scapholunate Ligament Reconstruction, Ulnar Collateral Ligament Reconstruction, Radial Collateral Ligament Reconstruction, Carpometacarpal joint arthroplasty (basal thumb joint arthroplasty), Carpal Ligament Reconstructions and repairs, tendon transfer in the hand/wrist

## Summary of Technological Characteristics

The OSSIOfiber® Interference Screws have the same intended use, and principles of operation, and similar indications for use, material composition and design characteristics as the predicate devices (K202535, K240441). The indications of the subject device are identical to the primary predicate (K202535), except slightly different wording relating to the repair/reconstruction of the knee, which is similar to the wording of the additional predicate (K240441). The OSSIOfiber® Interference Screws include indications for use in pediatric patients, which are not present in the predicate device (K202535, K240441). The difference in the identified patient population does not alter the intended use, as the design, materials, and performance characteristics are appropriate for both adult and pediatric applications. The OSSIOfiber® Interference Screws have identical intended use, material composition, principles of operation, manufacturing and sterilization methods (sterilized by EtO), and similar indications for use as their reference devices (K251309, K243760). The material, manufacturing and sterilization methods of the subject device are also the same as that of the cleared K231272 reference device. The OSSIOfiber® subject devices are available in sizes appropriate for the children and adolescents patient population. Although there are slight design and material differences compared to the primary predicate, mechanical testing demonstrated at least equivalent performance both initially and after in-vitro degradation. Thus, any differences between the subject devices and their predicates do not raise different questions of safety and effectiveness.

## Non-Clinical Data

Pull-out testing was performed to verify the strength and fixation properties of the OSSIOfiber® Interference Screws, and to compare them to those of the primary predicate device (K202535). Testing was done initially

{6}

Page 3 of 3

and following in-vitro degradation. The in-vitro degradation profile was characterized. Torsional strength and driving torque testing at time zero were also conducted for the OSSIOfiber® Interference Screws.

Biocompatibility for the subject device was established primarily based on the referenced ISO 10993 data from the previously cleared reference devices (K231272, K251309, K243760) and a rationale.

## Conclusions

The OSSIOfiber® Interference Screw is as safe and effective as its primary predicate device, Arthrex FastThread Interference Screw (K202535). The OSSIOfiber® Interference Screw have the same intended use, and principles of operation, and similar indications for use, material composition and design characteristics as the predicate devices. The OSSIOfiber® Interference Screw have identical intended use, material composition, principles of operation, manufacturing and sterilization methods (sterilized by EtO), and similar indications for use as their reference devices (K251309, K243760). Any minor differences do not alter the intended surgical use of the device and do not affect its safety and effectiveness when used as labeled. Non-clinical testing data demonstrate that the OSSIOfiber® Interference Screw is at least as safe and effective as the primary predicate device. Thus, the OSSIOfiber® Interference Screw is substantially equivalent to its predicate devices.
