Intended Use

OSSIOfiber® Compression Screws are indicated for maintenance of alignment and fixation of bone fractures, comminuted fractures, fragments, osteotomies, and bone grafts, of the upper extremity, fibula, knee, ankle and foot in the presence of appropriate brace and/or immobilization.

Device Story

Cannulated bone screw for orthopedic fixation; composed of degradable PLDLA polymer reinforced with mineral fibers. Implanted by surgeons in clinical settings to maintain alignment of fractures, osteotomies, or bone grafts. Device degrades via hydrolysis into metabolites; load transfers to healing bone over time; eliminates need for hardware removal surgery. Used with standard ISO 5835/ISO 9714 compatible instrumentation. Provides mechanical fixation during healing; benefits patient by avoiding secondary removal procedures.

Clinical Evidence

Bench testing only. Pull-out testing performed to verify fixation properties compared to metal predicate (K133842) at time zero and following in-vitro degradation. Torsional testing and rationale provided for driving torque. Biocompatibility and degradation profiles established via reference to previously cleared devices (K193660, K203465).

Technological Characteristics

Cannulated bone screw; material: degradable poly (L-lactide-co-D, L-lactide) (PLDLA) reinforced with continuous mineral fibers. Dimensions: 3.5 mm diameter, 14-50 mm length. Compatible with ISO 5835/ISO 9714 instrumentation. Sterile, single-patient use.

Indications for Use

Indicated for patients requiring maintenance of alignment and fixation of bone fractures, comminuted fractures, fragments, osteotomies, and bone grafts in the upper extremity, fibula, knee, ankle, and foot, requiring concurrent bracing or immobilization.

Regulatory Classification

Identification

A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.

## OSSIOfiber® Compression Screw, 3.5mm

#### Submitter

## Ossio Ltd.

8 HaTochen Street, Caesarea, Israel, 3079861 Phone: [phone] Facsimile: [phone] Contact Person: Taly Lindner Date Prepared: November 12, 2021

Name of Device: OSSIOfiber® Compression Screw, 3.5mm

Common or Usual Name: Screw, Fixation, Bone

Classification Name: Smooth or threaded metallic bone fixation fastener

Regulatory Class: Class II, 21 C.F.R. § 888.3040

Product Code: HWC

#### Predicate Devices

OSSIOfiber® Compression Screw (K193660) - Primary Predicate

Tyber Medical Compression Screw (K133842)

### Reference Devices

OSSIOfiber® Cannulated Trimmable Fixation Nail (K203465)

#### Purpose of Submission

This traditional 510(k) premarket notification is submitted to obtain clearance for an additional screw design made of the same material including lengths outside the previously cleared range of the OSSIOfiber® Compression Screw family (named OSSIOfiber® Compression Screw, 3.5mm).

#### Device Description

The OSSIOfiber® Compression Screws are cannulated bone screws made of degradable poly (Llactide-co-D, L-lactide) (PLDLA) reinforced with continuous mineral fibers. The polymer content degrades by hydrolysis into alpha-hydroxy acids that are metabolized by the body. The fibers are made of 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 Screws are supplied sterile, for single patient use only. The screws are partially threaded and have a cannulated design. The additional devices included in this submission are: 14- 50 mm long, and 3.5 mm diameter.

{4}------------------------------------------------

#### K213596

The OSSIOfiber® Compression Screws are designed to be used with commonly available orthopedic surgical tools such as ISO 5835/ISO 9714 compatible instrumentations.

## Indications for Use

OSSIOfiber® Compression Screws are indicated for maintenance of alignment and fixation of bone fractures, comminuted fractures, fragments, osteotomies, and bone grafts, of the upper extremity, fibula, knee, ankle and foot in the presence of appropriate brace and/or immobilization.

# Summary of Technological Characteristics

The OSSIOfiber® Compression Screws, 3.5mm have the same intended use, indications for use, material composition, manufacturing and sterilization methods and principles of operation as the primary predicate device (K193660). Although there are differences with regards to shape and length as compared to the predicate devices, mechanical pull-out testing demonstrated at least equivalent performance both initially and after in vitro degradation. Any differences between OSSIOfiber® Compression Screws, 3.5mm and its predicate devices do not raise different questions of safety and effectiveness.

# Non-Clinical Data

Pull-out testing was performed to verify the fixation properties of the OSSIOfiber® Compression Screw, 3.5mm, and to compare them to those of the metal predicate device (K133842). Testing was done initially and following in-vitro degradation. Torsional testing and rationale were also provided to support the torsional strength and driving torque at time zero for the OSSIOfiber® Compression Screw, 3.5mm.

In vitro degradation and biocompatibility for the implants were established based on the cleared primary predicate device (K193660) and referenced device (K203465). A rationale was provided to support the MR safe labeling of the device.

## Conclusions

The OSSIOfiber® Compression Screw, 3.5mm is as safe and effective as its predicate devices. The OSSIOfiber® Compression Screws, 3.5mm have the same intended use, indications for use, material composition, manufacturing and sterilization methods and principles of operation as the primary predicate device (K193660). The minor design differences and additional lengths do not alter the intended surgical use of the device and do not affect its safety and effectiveness when used as labeled. Non-clinical pull-out testing data and torsional rationales demonstrate that the OSSIOfiber® Compression Screw, 3.5mm is at least as safe and effective as its predicates (K193642). Thus, the OSSIOfiber® Compression Screws, 3.5mm are substantially equivalent to its predicate devices.
