Device Story

KFx Suture Lock Nail Bone Anchor is a bone fixation fastener; used as part of KFx Tissue Fixation System. System includes Nail Bone Anchor, Bone Screw Anchor, and re-usable surgical instruments. Device captures sutures to secure soft tissue to bone; eliminates need for manual suture knots. Used in orthopedic surgeries (shoulder, foot/ankle, knee, hand/wrist, elbow). Operated by surgeons in clinical/OR settings. Provides mechanical fixation of soft tissue to bone; benefits patient by facilitating stable tissue-to-bone attachment during healing. Device provided sterile via Ethylene Oxide (EO) gas.

Clinical Evidence

Bench testing only. No clinical data provided. Bench test results indicate device is safe and satisfies functional performance requirements.

Technological Characteristics

Bone fixation fastener; metallic construction. Materials are biocompatible. Provided sterile via Ethylene Oxide (EO) gas (SAL 10^-6). System includes Nail Bone Anchor, Bone Screw Anchor, and re-usable surgical instruments.

Indications for Use

Indicated for fixation of soft tissue to bone in shoulder, foot/ankle, knee, hand/wrist, and elbow for patients requiring ligament, tendon, or capsular repair/reconstruction.

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.

#### INTENDED USE

The intended use of the KFx Suture Lock Tissue Fixation System is for the fixation of soft tissue to bone in the shoulder, foot/ankle, knee, hand/wrist, and elbow.

#### Specifically:

Shoulder: Bankart lesion repairs, SLAP lesion repairs, acromio-clavicular separation repairs, rotator cuff repairs, capsular shift or capsulolabral reconstructions, biceps tenodesis, deltoid repairs.

Foot and Ankle: Hallux valgus repairs, medial or lateral instability repairs/reconstructions, Achilles repairs/reconstructions, mid-foot reconstructions, metatarsal ligament repair.

Knee: Medial collateral ligament repairs, lateral ligament repairs, posterior oblique ligament repairs, lliotibial band tenodesis, patellar tendon repairs.

Hand, Wrist and Elbow: Scapholunate ligament reconstructions, ulnar or radial collateral ligament reconstructions, tennis elbow repair, biceps tendon reattachment.

#### EQUIVALENT DEVICE

The KFx Suture Lock Nail Bone Anchor is similar in basic design, technology, construction and mechanical performance to the Suture Lock Nail Bone Anchor included in the KFx Tissue Fixation System previously cleared under 510(k) K072063. Intended use is identical. Device modification includes use of an additional biocompatible material.

### BIOCOMPATIBILITY AND PERFORMANCE DATA

The materials used in the KFx Suture Lock Nail Bone Anchor are biocompatible. The same materials are used in a myriad of legally marketed orthopedic devices.

Bench test results indicate that the device is safe and satisfies functional performance requirements when used as indicated and do not raise new issues of safety or effectiveness.

## CONCLUSIONS DRAWN FROM STUDIES

The test results demonstrate that the modified KFx Suture Lock Nail Bone Anchor is substantially equivalent to the currently marketed predicate device.
