Indications for Use
The Bionx Suture Anchor is indicated for use in arthroscopic or open surgical procedures to reattach ligaments to the shoulder bone, i.e., for rotator cuff or Bankart lesion repair. The device may be attached to either the articular facet surface or to a metaphyseal region of the bone, provided that the thickness of the cortex is less than 1.5 mm.
Device Story
Biodegradable threaded suture anchor; 15 mm length, 3.8 mm diameter; square head design with transverse channels for suture retention. Used in arthroscopic or open shoulder surgery by orthopedic surgeons. Surgeon drills 3.5 mm hole; inserts anchor using specialized tool; secures ruptured ligament to bone via suture. Device remains in situ during healing; gradually degrades and is absorbed by body; eliminates need for surgical removal. Provides mechanical fixation of soft tissue to bone.
Clinical Evidence
Bench testing only. Performance data confirms adequate pullout and torsional strength for intended use.
Technological Characteristics
Threaded screw anchor; 15 mm length, 3.8 mm diameter; material: biodegradable polylactide polymers; mechanical fixation via interference fit; manual insertion tool.
Indications for Use
Indicated for patients undergoing arthroscopic or open surgical procedures for reattachment of ligaments to shoulder bone, specifically for repair of Bankart lesions or rotator cuff tears. Applicable to sites with cortical bone thickness less than 1.5 mm.
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.

#### Indications for Use
The Bionx Suture Anchor is indicated for use in arthroscopic or open surgical procedures to reattach ligaments to the shoulder bone, i.e., for repair of Bankart lesions or rotator cuff tears. The device may be attached to either the articular facet surface or to metaphyseal region of the bone, provided that the thickness of the cortex is less than 1.5 mm.
#### Principles of Operation
The Bionx Suture Anchor is a threaded screw with a square head which is 15 mm in length and 3.8 mm in diameter. The design of the screw incorporates two channels which are cut transversely through the threads on opposite sides of the device to create a groove to hold the suture. To use the suture anchor, the surgeon first prepares the implantation site by drilling a 3.5 mm hole through the cortical bone into the cancellous bone. The surgeon then inserts the square head of the anchor into the square recess on the end of the insertion tool; an interference fit securely holds the anchor in place. A suture is then placed into the channels on either side of the anchor, threaded through a groove in the insertion tool's shaft, and held in place in a slot on the insertion tool's handle. The surgeon rotates the driver to screw the anchor into the hole and uses the suture to secure the ruptured ligament to the bone at the site of the anchor insertion. The ligament remains secured to the bone throughout the healing period. after which the anchor
{2}------------------------------------------------
gradually degrades and is completely absorbed by the body. Thus, there is no need to surgically remove the anchor.
### Technical Characteristics
The Bionx Suture Anchor, the American Medical Electronics, Inc. Ogden Anchor ("Ogden"), the Zimmer, Inc. Statak® Soft Tissue Attachment Device ("Statak®"), the Arthrex, Inc. FASTak™ Suture Anchor ("FASTak™"), the Mitek Surgical Products, Inc. GII Anchor ("Mitek GII"), and the Smith & Nephew Endoscopy, Inc. Acufex® TAG Suture Anchor ("Acufex® TAG") possess similar technical characteristics. All of these devices are intended for use to anchor sutures to the bone in orthopedic surgical procedures to reattach soft tissue to bone. The Bionx Suture Anchor, the Ogden, the Statak®, and the FASTak™ are all screw anchors, while the Mitek GII is a "barbed" anchor, and the Acufex® TAG is a wedge shaped anchor. However, this difference in configuration does not raise any new questions of safety or effectiveness because the devices incorporate similar features to ensure that they remain fixed in the bone. In addition, although the Bionx Suture Anchor is made of biodegradable polymers, while the Ogden, the Statak®, the Mitek GII, and the FASTak™ are composed of titanium, and the Acufex® TAG is composed of biodegradable polyglyconate, this difference in materials does not raise any new questions of safety or effectiveness. The polylactide materials used in the Bionx Suture Anchor are substantially the same as the materials that have been used in other previously cleared implantable devices. Moreover, the biocompatibility of these materials has been established in the medical literature, and all of the materials possess sufficient strength for soft
{3}------------------------------------------------
tissue repair. Performance data confirms that the Bionx Suture Anchor possesses adequate pullout strength and torsional strength for its intended use.
## Summary Basis for the Finding of Substantial Equivalence
Like the previously cleared Ogden, the Statak®, the FASTakTM, the Mitek GII, and the Acufex® TAG, the Bionx Suture Anchor is intended for use to anchor the suture to the bone in orthopedic procedures to reattach soft tissue to bone in the shoulder. Furthermore, all of the suture anchors possess similar principles of operation and technical characteristics. The minor differences in the technical characteristics of the two devices, such as differences in the configuration, do not raise new questions of safety or effectiveness, as confirmed by performance testing. Thus, the devices are substantially equivalent.
