Device Story

Headed Bio-Absorbable Corkscrew is a threaded, bio-absorbable fastener used for soft tissue-to-bone fixation in orthopedic procedures. Device is manufactured from poly (L, DL-lactide). Surgeon prepares bone site using a tap before driving the anchor into place using an associated driver. Device provides mechanical fixation for various repairs including rotator cuff, Bankart, SLAP lesions, biceps tenodesis, and ligament reconstructions across multiple joints (shoulder, knee, ankle, wrist, elbow). By securing soft tissue to bone, the device facilitates healing and stabilization of the injured joint. Clinical benefit is derived from the bio-absorbable nature of the material, eliminating the need for secondary removal surgery.

Clinical Evidence

Bench testing only. Pull-out strength testing was conducted using 20 lb. density foam blocks to simulate poor quality bone, comparing the subject device (79.3 lbs.) against predicates including FASTak (55.40 lbs.), Bio-Statak (69-71 lbs.), and Bio-Anchor (29-49 lbs.). No clinical data provided.

Technological Characteristics

Material: Poly (L, DL-lactide). Design: Threaded fastener with slotted rounded head. Dimensions: 5.0mm. Insertion: Screw-in (requires pre-tapping of bone). Energy source: None (mechanical). Sterilization: Not specified.

Indications for Use

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

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.

| Trade Name: | Arthrex Headed Bio-Absorbable Corkscrew |
|-----------------|------------------------------------------------|
| Common Name: | Bio-Absorbable Corkscrew Fastener |
| Classification: | Fastener, Fixation, Biodegradable, Soft Tissue |

### Description:

The Headed Bio-Absorbable Corkscrew is manufactured using poly (L, DL-lactide). It is a threaded design with a rounded head which is slotted to accept the associated driver. Prior to driving in the anchor, it is necessary to prepare the bone using a tap.

#### Intended Use:

The Headed Bio-Absorbable Corkscrew is intended for fixation of soft tissue to bone. This product is intended for the following indications:

Shoulder: Rotator Cuff Repair, 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

Knee: Medial Collateral Ligament Repair, Lateral Ligament Repair, Patellar Tendon Repair, Posterior Oblique Ligament Repair, Iliotibial Band Tenodesis

Hand/Wrist: Scapholunate Ligament Reconstruction, Ulnar Collateral Ligament Reconstruction, Radial Collateral Ligament Reconstruction

Elbow: Biceps Tendon Reattachment, Tennis Elbow Repair, Ulnar or Radial Collateral Ligamant Reconstruction

## Substantial Equivalence:

Substantial equivalence is substantiated when a device has the same intended use and the same technological characteristics as the predicate device, or has the same intended use and different technological characteristics, but it can be demonstrated that the device is as safe and effective as the predicate device and does not raise different questions regarding safety and effectiveness

from the predicate device.

A substantial equivalence comparison is given in Table A.

In regards to the material. Poly (L.DL-Lactide), it is currently used in the Synthes Polypin which recently received FDA marketing clearance. This material has undergone extensive in-vitro and in-vivo testing by Synthes.

In addition to the testing performed by Synthes, an independent evaluation of the material was conducted by Claes et. al. ("New bioresorbable pin for the reduction of small bony fragments: design, mechanical properties and in vitro degradation" - Biomaterials, 1996, Vol. 17 No. 16).

None of the aforementioned differences make the Arthrex Headed Bio-Absorbable Corkscrew any less safe and effective than the predicate devices. Furthermore, they do not raise any different questions regarding safety and effectiveness from the predicate devices.
