POSTERIOR SPINE TRUSS SYSTEM (PSTS) INTERBODY FUSION DEVICE INSTRUCTIONS FOR USE PLEASE READ CAREFULLY CAUTION: FEDERAL LAW (USA) RESTRICTS THESE DEVICES TO SALES BY OR ON THE ORDER OF A PHYSICIAN. INTENDED USE: The Posterior Spine Truss System (PSTS) Interbody Fusion Device is designed to provide mechanical support to the lumbar spine while biologic fusion takes place. DEVICE DESCRIPTION: The device is an open architecture truss design mathematically formulated to provide structural support with open space throughout the implant for bone growth and fusion. The 4WEB additive manufacturing process provides a hierarchical surface roughness. The implant is made from Ti6Al4V alloy. The device is available in a variety of sizes and lordotic angles to accommodate the patient’s anatomy. INDICATIONS FOR USE: The Posterior Spine Truss System (PSTS) Interbody Fusion Device is indicated for use in skeletally mature patients with Degenerative Disc Disease (DDD) at one or two contiguous levels from L2-S1. DDD is defined as discogenic back pain with degeneration of the disc confirmed by patient history and radiographic studies. Patients should have received 6 months of non-operative treatment prior to treatment with the devices. The device must be used with supplemental fixation and must be used with autograft and/or allogenic bone graft comprised of cancellous and/or corticocancellous bone graft. These DDD patients may also have up to Grade I spondylolisthesis or retrolisthesis at the involved level(s). CONTRAINDICATIONS: The PSTS Interbody Fusion Device should not be implanted in patients with: • An active infection at the operative site or other active systemic infections • Tumor involvement at the operative site • Prior fusion at the level(s) to be treated • Known sensitivity to the material WARNINGS AND PRECAUTIONS: Safety and effectiveness have not been established in the following conditions: • Gross obesity • Three or more levels to be fused • Symptomatic cardiac disease • Pregnancy • Previous fusion attempts at the involved level(s) • Spondylolisthesis or retrolisthesis greater than Grade I • Significant loss of bone stock as seen with osteoporosis or osteomalacia • Conditions requiring chronic corticosteroid use • Active drug abuse The PSTS Interbody Fusion Device is for single use only. Bending or fracture of the implants or instruments can occur if not handled properly. All sizers and instrumentation are provided non-sterile and must be steam sterilized prior to use. No implant should be reused if it has come in contact with blood or other bodily fluids. All implants, sizers and instrumentation should be inspected prior to use for possible damage or defects. Any damaged or defective component should not be used and should be returned to 4WEB. Interbody fusion devices are intended to provide mechanical support while biologic fusion occurs. In the event of pseudoarthrosis or delayed fusion, the risk of implant migration, loosening or breakage increases. The physician/surgeon should consider the levels of implantation, patient weight, patient activity level, other patient conditions, etc. which may impact the performance of the system. Only surgeons trained in lumbar spine fusion procedures should implant this device. OPERATIVE PRECAUTIONS: The surgeon is to be thoroughly familiar with the PSTS Interbody Fusion Device, methods of application, instruments and surgical technique. Correct positioning of the PSTS Interbody Fusion Device relative to the vertebrae should be checked intraoperatively with x-ray. The size (and more particularly the height) of the PSTS Interbody Fusion Device must be chosen on the basis of the patient’s anatomy and desired correction. Each PSTS Interbody Fusion Device is to be filled with autologous and/or allograft bone to promote bone fusion (See Surgical Technique Manual for complete details). The implants are for single-implant use only. An explanted implant must never be re-implanted. Stresses and fracture, even though not noticeable by visual inspection, may have been created during initial implantation. Following implantation, the product number and manufacturing lot number of the device that has been implanted must be reported in the patient’s surgical file. POTENTIAL ADVERSE EVENTS: Potential adverse events may be related to surgery in general, spine surgery specifically or the device. These may include, but are not limited to the following: • Adverse events related to any surgery: reactions to anesthesia, the anesthetic or other medications; bleeding; infection; ileus; blood vessel damage; nerve or soft tissue damage; atelectasis; pneumonia; hematoma; seroma; wound dehiscence or incisional hernia; urologic problems; embolism; anemia; colitis; thrombophlebitis; heart attack; stroke; or death. • Adverse events related specifically to spine surgery: dural tear and CSF leak; nerve damage leading to radiculopathy, myelopathy, paraparesis, paresthesia or paralysis; meningitis; vertebral body damage or fracture; ligament damage; fractured sacrum; or retrograde ejaculation. • Adverse events related to the device: implant crack or fracture, failure to achieve fusion, implant migration, dislodgement, or metal sensitivity to a foreign body, including possible tumor formation. Additional surgery may be necessary for implant removal, repositioning or replacement. Additional stabilization at the implanted level or surgery at another disc level may be necessary if non-union or anatomic change at an adjacent level develops. POSTOPERATIVE CARE: The physician’s postoperative directions and warnings to the patient and the corresponding patient compliance are extremely important. • Detailed instructions on the use and limitations of the device must be given to the patient. The patient must be warned that loosening, and / or breakage of the device(s) are complications which may occur as result of early or excessive weight-bearing, muscular activity or sudden jolts or shock to the spine. • The patient must be advised not to smoke or consume alcohol during period of the bone fusion process. • The patient must be advised of the inability to bend at the point of spinal fusion and taught to compensate for this permanent physical restriction in body motion. • It is critical that immobilization of union is established and confirmed by roentgenographic examination. If a non-union develops or if the components loosen, migrate, and / or break, the devices must be revised and / or removed immediately before serious injury occurs. • Any retrieved devices are not to be used in another surgical procedure. WARNINGS: • Follow the instructions and warnings issued by the suppliers of any cleaning and disinfection agents and equipment used. • Do not exceed 140° C (284° F) during reprocessing steps. • Highly alkaline conditions can damage products with aluminum parts. • Avoid exposure to hypochlorite solutions, as these will promote corrosion. • Scratches or dents can result in breakage. • For instruments produced by another manufacturer, reference the manufacturer’s instructions for use. • Care should be taken to remove any debris, tissue or bone fragments that may collect on the instrument. LIMITATIONS ON REPROCESSING: • End of useful life is generally determined by wear or damage in surgical use. • Carefully inspect instruments between uses to verify proper functioning and configuration. • Damaged instruments must be replaced to prevent potential patient injury such as loss of metal fragments into the surgical site. DECONTAMINATION CONSIDERATIONS - CREUTZFELDT-JAKOB DISEASE (CJD): • Under certain classifications of risk, the World Health Organization (WHO) or local regulatory authorities recommend special CJD (Creutzfeldt-Jakob Disease) inactivation processing procedures. For use of this product outside the United States, consult WHO and local regulations for further information. REPROCESSING INSTRUCTIONS CARE AT THE POINT OF USE: • Use purified water obtained via ultra-filtration, RO, DI and/or distilled. • Thoroughly clean instruments as soon as possible after use. If cleaning must be delayed, immerse instruments in a compatible pH neutral detergent solution and purified water to prevent drying and encrustation of surgical soil. • Avoid prolonged exposure to saline to minimize the chance of corrosion. • Remove excessive soil with a disposable low lint wipe. CLEANING: ALL INSTRUMENTS • Instructions for instruments requiring disassembly for cleaning may be found in the Surgical Technique Manual (ST-PSTS-01). • Prepare an enzymatic cleaning solution in accordance with the manufacturer’s instructions (1oz Enzol, or equivalent, per gallon of purified water).
