The ASTRA Spine System is designed for spine surgeons to achieve optimal deformity correction. It offers a comprehensive selection of implants and instruments, noted for performance, ease of use, and versatility in spine surgery procedures.
The system stabilizes the lumbar and thoracic spine using titanium or cobalt chrome alloy rods, polyaxial and uniplanar screws with dual core technology, cross connectors, and color-coded components for easy identification.
Detailed catalog numbers are provided for various screws, set screws, washers, cross connectors, and hooks, designed for specific surgical needs and available in multiple sizes and configurations.
The system includes a range of instruments to facilitate the surgical process, though specific details are not provided in the excerpt.
Techniques for using hooks and pedicle screws are outlined, emphasizing adaptability for deformity correction.
Guidelines for revision or removal of implants ensure the system can be adjusted or removed as necessary.
Detailed instructions are provided to ensure proper application and patient safety.
- Rod Types: Titanium and cobalt chrome rods are available in various configurations and sizes.
- Hook Types: Includes transverse process hooks, laminar hooks, and offset hooks for specific spinal regions and techniques.
- Hook Site Preparation: Details anatomical considerations and techniques for hook insertion.
- Rod Contouring and Insertion: Describes contouring rods to fit spinal curvature and securing them.
- Pedicle Preparation: Lists instruments for preparing the pedicle site.
- Implant Instruments: Includes tools for handling and positioning implants.
- Rod Correction Maneuvers: Tools specified for adjusting and securing rods.
- Screws and Nuts Instruments: Details drivers and torque-limiting handles for securing screws and nuts.
- Rod Bending: Emphasizes pre-bending cobalt chrome rods and using specific benders for minor corrections.
- Rod Reduction: Suggests using the Forceps Rocker method for seating rods into implants.
Rod rotation into final position is done slowly to prevent neurological changes, with methods suggested to stabilize hooks during rotation.
Used for final adjustments in sagittal and coronal planes, with further correction through rod rotation or in-situ bending.
Performed to position hooks, with Rod Clamps recommended as stops for distraction maneuvers.
After deformity correction, the opposite side is prepared for the stabilizing rod.
Performed using specific drivers and torque-limiting handles, with transverse connectors placed for stability.
Facet joints are cleaned, and osteotomy is performed to enhance visualization and fusion.
A posterior cortical breach is created, and the Thoracic Pedicle Probe is used to locate the cancellous bone entrance.
Polyaxial and Uniplanar Screws are inserted using specific screwdrivers, with features to simplify rod placement.
Rods are contoured to match spinal curvature and clamped to prevent rotation.
If not fully seated, Persuaders or Forceps Rockers are used to seat the rod.
Set screws are kept loose, and the concave rod is straightened with In-Situ Coronal Benders.
The iliac wing is exposed, and the Iliac Screw is placed with a specific trajectory.
The system includes various components such as rods, pedicle screws, and connectors, available in titanium and cobalt chromium alloys.
- Rod and Connector Application: Set screws must be tightened using specific tools.
- Rod-to-Rod Connectors: Used to extend or revise constructs.
- Final Tightening: Ensures rods are locked in place.
- Cross Connector Placement: Stabilizes constructs.
- Removal Procedures: Outlined for removing components.
Components like the Z Revision Rod and In-Line Connector Module are included for extending or revising constructs.
- Indications: Intended for spinal stabilization in various conditions.
- Packaging and Sterilization: Components must be sterilized before use.
- Cleaning and Inspection: Instruments must be cleaned and inspected before sterilization.
Surgeons must inform patients about limitations and potential complications. Implants are temporary and may require removal after bone fusion.
The system is intended to stabilize the spine during bone fusion, with emphasis on immobilization confirmed by X-rays.
Conditions that can be managed without internal fixation devices are contraindications.
Correct implant selection is crucial, and mixing metals is warned against due to corrosion risks.
Potential adverse effects include implant breakage and metal fatigue. Patient selection is critical.
Sterilized products should be stored in a controlled environment.
Postoperative instructions are vital for successful bone healing.
Implantation can lead to various risks, and factors such as implantation levels and patient weight should be considered.
Adverse effects include implant bending, fracture, loosening, and migration.
Pediatric patients may face additional risks such as malpositioning of screws and junctional kyphosis.
Healthcare professionals should report any dissatisfaction or malfunction to the distributor or SpineCraft.
The system is sold with a limited warranty against defects in workmanship and materials.
