SYSTEM VALUES AND MECHANISM OF ACTION

SYSTEM VALUES

MECHANISM OF ACTION

– Typical 15 minute implantation time 1

– Reduced overall procedure time compared with pedicle screw based fi xation systems 1,2

– One size: Novel adjustable band locking mechanism allows adjustment to patient size and anatomy– Band fi xation results in less procedural morbidity compared to pedicle screw fi xation 1,3,4

– The LimiFlex™ Paraspinous Tension Band is designed to work in parallel with ligaments and facets, and utilizes low forces to minimize loads on the anatomy 5

– The LimiFlex™ Paraspinous Tension Band maintains sagittal lordosis while preventing progressive slip and translation 1

The LimiFlex™ Paraspinous Tension Band restores the range of motion of a destabilized segment and increases segmental stiffness, as demonstrated in biomechanical testing. Limiting flexion has a corresponding effect on translational instability. 5

PRECAUTIONS

PRECAUTIONS

It is important to read the Instructions for Use (IFU) prior to use of the LimiFlex™ Paraspinous Tension Band. The surgical procedure described in this Surgical Technique Manual is supplementary to and is adapted from the steps provided in the IFU

Preoperative planning and familiarity with the LimiFlex™ surgical technique are essential. Do not use this product if you have not been properly trained in its use.

Do not re-use / Do not resterilize. Reuse, reprocessing or re-sterilization of the device may compromise the structural integrity of the device and / or create a risk of contamination of the device, which could result in patient injury, illness, or death.

The LimiFlex™ Device and Leaders are sterilized with ethylene oxide. They are provided sterile unless the package is opened or damaged. Inspect the LimiFlex™ Device, Leaders and packaging before use to verify that no damage has occurred to the sterile packaging and that all product remains properly positioned in the packaging.

The LimiFlex™ Instruments and LimiFlex™ Instrument Tray are reusable and must be cleaned and sterilized prior to each use in accordance with the cleaning and sterilization instructions (see pages 32-34).Do not alter the pre-assembled device, accessory, or instruments prior to use of the devices.

Throughout the entire procedure, do not engage the Locking Driver with the LimiFlex™ Device unless both rods are loaded onto Holders and the Symbol Plate is in place on top of Holders. Do not engage the Locking Driver with the LimiFlex™ Device before the procedure: doing so could impede proper implantation. The LimiFlex™ Device is provided pre-aligned in its packaging to facilitate the threading of the tips of the bands through the attachment mechanisms of the rods.

The device must be appropriately adjusted for the individual patient, taking anatomical and biomechanical factors into account.

The LimiFlex™ Device should be implanted only while using radiographic visualization; imaging should be utilized during implantation to ensure titanium rods are appropriately positioned and tensioned. Use the LimiFlex™ Instruments and Leaders (accessory) to implant the LimiFlex™ Device.

The use of one or more LimiFlex™ Device(s) to treat multiple segments in the same patient has not been studied.

Do not use a single LimiFlex™ Device to treat multiple segments or attach a single LimiFlex™ Device to two non-adjacent spinous processes.

Note:For additional information and a complete list of indications, contraindications, procedure steps, warnings, precautions, cautions, potential adverse events, and directions for use, please see the LimiFlex™ Paraspinous Tension Band Instructions for Use.

PRE-OPERATIVE PLANNING

PRE-OPERATIVE PLANNING

DecompressionIf decompression is performed, ensure a thorough, adequate decompression. (LimiFlex™ provides segmental stabilization, but does not provide mechanical decompression.)

Patient Position for LimiFlex™ ImplantationThe patient should be in a neutral or slightly extended position (approximating a standing posture) for optimal device tensioning.

If decompression is performed in a fl exed position, the patient will need to be re-positioned prior to tensioning the LimiFlex™.

LigamentsThe interspinous and supraspinous ligaments (ISL/SSL) at the implantation level may be resected and LimiFlex™ will still provide biomechanical stability. If possible, leave the ISL/SSL at the adjacent segments intact.

FacetsFacet incompetence is contraindicated because the LimiFlex™ Device requires facets that can resist shear loads.

Partial, undercutting facetectomy and foraminotomy may be performed. Ensure that the articular surface of the facet is preserved.

Spinous ProcessesManually confi rm the competence of the spinous processes after decompression, prior to implantation.

Up to ½ of each spinous process (cranial-caudal) may be resected.

Bone QualityLimiFlex™ may be implanted in patients with osteopenia or osteoporosis, however LimiFlex™ should not be used in patients with severe osteoporosis (T-score ≤ –2.5 with fragility fracture1).

SURGICAL PROCEDURE

INCISION, DECOMPRESSION, AND PATIENT POSITIONING

Midline incision with bilateral fascial incisionsCreate a midline longitudinal incision at the affected level, followed by parallel bilateral fascial incisionsadjacent to the supraspinous ligament. Elevate the paraspinal musculature off of the spinous processesand laminae bilaterally. After decompression, if performed, reposition the patient if necessary to create the appropriate segmental alignment.

Decompression Decompression may be performed per standard technique (e.g., bilateral/midline-sparing, unilateral, midline, etc.).

Patient positioning After decompression, if performed, reposition the patient if necessary to create the appropriate segmental alignment.

Note: Manually confirm the competence of the spinous processes and facets after decompression, prior to implantation. Up to ½ of each spinous process (cranial-caudal) may be resected.

SURGICAL PROCEDURE

READJUSTMENT & UNLOCKING THE BAND (IF REQUIRED)

Unlock bandTurn Locking Driver counter-clockwise until flag is in unlock zone on Symbol Plate.

If both sides require re-adjustment, repeat this step for the second side.

Repeat procedure starting from page 19 with locking of first band in order to tension, secure, and lock bands.

Note: The band is only to be unlocked if readjustment of the LimiFlex™ Device is desired, for example if the patient positioning or device cranial-caudal location is unsatisfactory.

Caution: If the Holders have already been removed prior to re-adjustment, do not engage the Locking Driver alone with the LimiFlex™ Device. Instead, ensure that both rods are loaded onto Holders and that Symbol Plate is in place on top of Holders prior to re-adjustment.

If re-adjustment is deemed necessary after Holder removal, re-apply Holders and Symbol Plate, re-insert Locking Driver into same position in which it was prior to removal, and proceed to appropriate steps to re-adjust.

If Holders cannot be re-applied for re-adjustment, cut bands if necessary, remove both rods and bands, and use another LimiFlex™ Device.

MRI INFORMATION

MRI INFORMATION

MR Conditional (Contact Simpirica Spine for additional information)

The LimiFlex™ Device was determined to be MR-conditional in non-clinical testing. A patient with this device can be scanned safely, immediately after placement under the following conditions:

Static Magnetic Field Static magnetic field of 3-Tesla or less Highest spatial gradient magnetic field of 720-Gauss/cm or less

MRI-Related Heating In non-clinical testing, the LimiFlex™ Paraspinous Tension Band produced the following temperature rises during MRI performed for 15-min of scanning (i.e., per pulse sequence):

1.5-Tesla/64-MHz 3-T/128-MHz

MR system reported, whole body averaged SAR

2.9-W/kg 2.9-W/kg

Calorimetry measured values, whole body averaged SAR

2.1-W/kg 2.7-W/kg

Highest temperature change 1.8° C 2.2° C

Artifact Information MR image quality may be compromised if the area of interest is in the exact same area or relatively close to the position of the LimiFlex™ Paraspinous Tension Band. Therefore, optimization of MR imaging parameters to compensate for the presence of this device may be necessary. The maximum artifact size (i.e., as seen on the gradient echo pulse sequence) extends approximately 10-mm relative to the size and shape of this implant.
