Spine implants have come a long way, revolutionizing the field of spine surgery and improving the quality of life for countless patients. As a leading manufacturer of spine implants, we’re proud to highlight the top five implants that are driving innovation and shaping the future of spine care.
Expandable Cages
Expandable cages are placed between two adjacent vertebrae following the removal of the intervertebral disc. They restore the disc height and spinal alignment, and they feature a hollow center to accommodate osteogenic material, such as autograft bone or synthetic substitutes like beta-tricalcium phosphate. The key innovation lies in their capacity to expand once deployed, allowing surgeons to tailor the device’s height and angle intraoperatively. This adaptability ensures improved contact with the vertebral endplates, promoting load sharing and reducing stress concentration.
Typically made from biocompatible materials such as titanium or polyetheretherketone (PEEK), these cages leverage material-specific properties for durability, radiolucency, and fusion compatibility. Titanium provides robust mechanical strength and promotes osseointegration, while PEEK offers elasticity similar to bone and allows for post-surgical imaging assessment without interference.
Clinical Advantages
Expandable cages offer several distinct advantages over static devices:
- Enhanced Endplate Contact: By conforming to individual endplate anatomy, expandable cages maximize load distribution Restoration of Lordosis: The adjustable design facilitates precise restoration of spinal alignment, particularly in conditions requiring correction of lumbar lordosis or cervical alignment.
- Minimally Invasive Applicability: Expandable cages are well-suited for minimally invasive surgical techniques, reducing operative time and postoperative recovery by allowing implantation through smaller incisions.
- Customization of Neural Foramina: Expansion increases the bony openings for nerve roots, reducing neural compression and associated symptoms in conditions like spinal stenosis or herniated discs.
Expandable cages are utilized in treating various spinal pathologies, including degenerative disc disease, spondylolisthesis, spinal tumors, and deformities such as scoliosis and kyphosis. They are particularly advantageous in revision surgeries where prior fusion attempts have failed or when addressing complex anatomical challenges. For hospital administrators and supply chain managers, the use of expandable cages aligns with goals of enhancing surgical outcomes while potentially reducing reoperation rates.
Standalone Cervical Cages
Among the top orthopedic implants, stand-alone cervical cages represent a transformative innovation in anterior cervical interbody fusion (ACIF) surgery. Devices like the Quasar™ Stand-Alone ACIF System exemplify the next generation of spinal implants, combining streamlined procedural efficiency with less invasive techniques. Designed to restore cervical disc height, maintain physiological spinal curvature, and achieve vertebral fusion, stand-alone cages have become a preferred choice in managing degenerative cervical spine pathologies.
Evolution of Cervical Implants
Traditionally, cervical fusion relied on a combination of interbody cages and plates to achieve spinal stability and alignment. While effective, these systems often required extensive surgical exposure and increased soft tissue disruption. Over the past few decades, stand-alone cervical cages have redefined the gold standard for cervical fusion by integrating the cage and plate into a single, seamless construct, simplifying the procedure while minimizing patient morbidity.
Key Features of the Quasar™ Stand-Alone ACIF System
The Quasar™ Stand-Alone ACIF System offers a cutting-edge approach to cervical fusion, leveraging advanced materials and engineering for optimal outcomes:
- Minimally Invasive Design: The central inserter requires less working space, reducing tissue trauma and operative time.
- Integrated Locking Plate: The system combines cage insertion and screw locking into one streamlined step, simplifying the surgical workflow.
- HA-PEEK Material: Made from Invibio™ HA-PEEK, the cage enhances bone ongrowth, achieving >75% direct bone contact at four weeks and improved apposition by 12 weeks.
Implant Highlights
- Cage Design:
- Constructed with HA-PEEK for enhanced biocompatibility.
- Available in three footprints to accommodate diverse patient anatomies.
- Tapered posterior edge for self-distraction during insertion.
- Plate Features:
- Zero-profile integration minimizes soft tissue irritation.
- Up to 36° cephalocaudal and 15° medial-lateral screw angulation for optimal positioning.
- Screw Options:
- Fixed or variable angle options.
- Self-drilling or self-tapping capabilities.
- Customizable lengths (12-26 mm) and diameters (3.6 mm or 4.1 mm).
Clinical Advantages
Stand-alone cervical cages, like the Quasar™ system, are associated with improved operative characteristics and postoperative outcomes compared to traditional cage-and-plate constructs. Key benefits include:
- Reduced Surgical Invasiveness: The integrated design eliminates the need for a separate cervical plate, reducing operative exposure and soft tissue disruption.
- Faster Procedures: Combining insertion and fixation into a single step shortens surgery time, lowering the risk of intraoperative complications.
- Less discomfort: As the construct is smaller compared to Plate and Cage construct, patients often report less discomfort swallowing.
Kyphoplasty
The Tracker Plus™ Kyphoplasty System exemplifies the cutting-edge evolution in treating thoracolumbar spine fractures, particularly vertebral compression fractures (VCFs) caused by osteoporosis or cancer. Over the past three decades, advancements in spinal care have prioritized minimally invasive techniques, and this system sets a new benchmark by combining precision-engineered tools with innovative materials. Designed to restore vertebral height, stabilize fractures, and alleviate pain, the Tracker Plus™ enables surgeons to achieve long-term deformity correction and spinal stability with reduced surgical aggression and fewer fused levels. For hospital administrators, surgeons, and medical distributors, this system not only streamlines procedures but also delivers superior patient outcomes, aligning seamlessly with modern goals of enhancing recovery and functional quality of life.
What Is Kyphoplasty?
Kyphoplasty, also referred to as balloon kyphoplasty or cementoplasty, is a minimally invasive procedure aimed at treating painful spinal compression fractures. Often performed on an outpatient basis, it involves:
- Percutaneous Access: Using a needle to access the affected vertebra, eliminating the need for large incisions.
- Balloon Inflation: A balloon catheter is introduced into the vertebra through the needle and inflated, restoring the vertebra’s height and correcting deformity.
- Cement Injection: Once the height is restored, medical-grade bone cement is injected into the cavity created by the balloon. The cement hardens quickly, stabilizing the fracture and reinforcing the bone structure.
The procedure is typically performed under local anesthesia, with or without sedation, although general anesthesia may be used in some cases. It is particularly effective for patients who experience severe pain that persists despite conservative treatments such as bed rest, physical therapy, or medication.
Pedicle Screws
Pedicle screws are a foundational component in modern spinal fusion surgeries, providing robust fixation and stability across nearly all levels of the spine. These screws are inserted into the vertebral pedicles and serve as anchor points for rods or plates, facilitating the alignment, stabilization, and fusion of spinal segments. Their versatility and effectiveness make them indispensable in a wide range of spinal procedures.
Key Benefits of Pedicle Screws
- Enhanced Stability: Pedicle screws deliver exceptional fixation, stabilizing the spine during the healing process and enabling secure support for adjacent hardware.
- Improved Fusion Outcomes: By promoting rigid fixation, pedicle screws enhance the conditions necessary for successful bone fusion and long-term healing.
- Deformity Correction: These screws are instrumental in correcting complex spinal deformities such as scoliosis and kyphosis, helping restore proper spinal alignment.
Pedicle screws are used across a variety of spinal fusion techniques, including ALIF (anterior lumbar interbody fusion), TLIF (transforaminal lumbar interbody fusion), and PLIF (posterior lumbar interbody fusion). After decompression surgery, where pressure on the spinal cord or nerves is relieved, pedicle screws stabilize the spine, preventing potentially harmful movement that could compromise the surgical outcome.
