Intended Use

Lorenz Sternal Closure System is intended for use in the stabilization and fixation of fractures of the anterior chest wall including Sternal fixation following Sternotomy and Sternal reconstructive surgical procedures.

Device Story

Lorenz Sternal Closure System consists of 2.4 mm diameter self-drilling titanium screws (lengths up to 16mm) for bone fixation. Used by surgeons in clinical/OR settings for sternal stabilization following sternotomy or reconstructive procedures. Self-drilling tip eliminates need for pre-drilling, though pre-drilling remains optional. Device provides mechanical fixation to facilitate bone healing; prevents sternal instability. Marketed as non-sterile, single-use; requires steam sterilization by user. Potential risks include implant migration, loosening, fracture, metal sensitivity, or impingement on internal chest structures if screws exceed sternal depth.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Titanium bone fixation screws; 2.4mm diameter; lengths up to 16mm; self-drilling tip design; non-sterile; single-use; steam sterilization required.

Indications for Use

Indicated for patients requiring stabilization and fixation of anterior chest wall fractures, including sternal fixation post-sternotomy and sternal reconstructive surgical procedures.

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.

Device Name: Lorenz Sternal Closure System

Classification Name: Single/multiple component metallic bone fixation appliances and accessories

Device Product Code: 87HRS (21 CFR 888.3030) Class II

Intended Use: Lorenz Sternal Closure System is intended for use in the stabilization and fixation of fractures of the anterior chest wall including Sternal fixation following Sternotomy and Sternal reconstructive surgical procedures.

Description: The Lorenz Sternal Closure System 2.4 self drilling screws are 2.4 mm in diameter and the lengths may range up to 16mm. The tip of the screw is designed so that a predrilled hole is not required, but may be used.

Material: Titanium

The Lorenz Sternal Closure System will be marketed as non-sterile, single use devices. Sterility Information: Steam Sterilization recommendations are included in the package insert.

Substantial Equivalence: Walter Lorenz considers the Lorenz Sternal Closure System equivalent to Lorenz Sternal Closure System (K011076 and K033740), Lorenz Self Drilling Screw (K013954) and Lorenz 2.4 Self Drilling Screw (K032228).

#### Possible risks:

- Poor bone formation, Osteolysis, Osteomyelitis, inhibited revascularization, or infection can 1. cause loosening, bending, cracking or fracture of the device.
- 2. Nonunion or delayed union, which may lead to breakage of the implant.
- 3. Migration, bending, fracture or loosening of the implant.
- 4. Metal sensitivity, or allergic reaction to a foreign body.
- খা Decrease in bone density due to stress shielding.
- 6. Pain, discomfort, abnormal sensation, or palpability due to the presence of the device.
- 7. Increased fibrous tissue response around the fracture site and/or the implant.
- 8. Necrosis of bone.
- 9. Inadequate healing.
- Selection of screws which are longer than the depth of the sternum may cause possible impingement on 10. structures internal to the chest wall including vessels, pleura and other structures.

Apart from these adverse effects there are always possible complical procedure such as, but not limited to, infection, nerve damage, and pain which may not be related to the implant.
