IMPORTANT INFORMATION ON THE CAPSTONE™ SPINAL SYSTEM
PURPOSE
DESCRIPTION
The Capstone™ Spinal System consists of PEEK cages, titanium alloy cages, and titanium cages of various widths and heights, which can be inserted between two lumbar or lumbosacral vertebral bodies to give support and correction during lumbar interbody fusion surgeries. The hollow geometry of the implants allows them to be packed with autogenous bone and/or allograft bone graft comprised of cancellous and/or corticocancellous bone graft, and/or demineralized allograft bone with bone marrow aspirate.
No warranties express or implied, are made. Implied warranties of merchantability and fitness for a particular purpose or use are specifically excluded.
INDICATIONS
The Capstone™ Spinal System is intended to be used in spinal fusion procedures for patients diagnosed with Degenerative Disc Disease (DDD) at one or two contiguous levels from L2 to S1. DDD patients may also have up to Grade 1 Spondylolisthesis or retrolisthesis at the involved levels. DDD is defined as discogenic back pain with degeneration of the disc confirmed by history
and radiographic studies. When used for these indications, the Capstone fixation systems cleared for use in the lumbar spine.
Additionally, the Capstone degenerative scoliosis as an adjunct to pedicle screw fixation.
These patients should be skeletally mature and have had six months of nonoperative treatment. The Capstone is intended to be used with autogenous bone and/or allograft bone graft comprised of cancellous and/or corticocancellous bone graft, and/or demineralized allograft bone with bone marrow aspirate when the subject device is used as an adjunct to fusion. These implants may be implanted via an open or a minimally invasive posterior approach. Alternatively, these implants may also be implanted via an anterior and/or transforaminal approach.

NOTA BENE: Although not absolute contraindications, conditions to be considered as potential factors for not using this device include:
Severe bone resorptionOsteomalaciaSevere osteoporosis
POTENTIAL ADVERSE EVENTS
Adverse effects may occur when the device is used either with or without associated instrumentation. The risk of adverse effects as a result of movement and non-stabilization may increase in cases where associated complementary support is not employed. Potential adverse events include:
Implant migrationBreakage of the device(s)Foreign body reaction to the implants including possible tumor formation, auto immune disease, and scarringPressure on the surrounding tissues or organsLoss of proper spinal curvature, correction, height, and reductionInfectionBone fracture or stress shielding at, above, or below the level of surgeryNon-union (or pseudoarthrosis)Loss of neurological function, appearance of radiculopathy, dural tears, and development of painNeurovascular compromise including paralysis, temporary or permanent retrograde ejaculation in males, or other types of
serious injury

vertebral body) and bone graft or bone graft harvest site at, above, or below the level of surgery
Retropulsed graftHerniated nucleus pulposus, disc disruption, or degeneration at, above, or below the level of surgeryLoss of or increase in spinal mobility or functionReproductive system compromise including sterility, loss of consortium, and sexual dysfunctionDevelopment of respiratory problems (e.g., pulmonary embolism, atelectasis, bronchitis, pneumonia, etc.)Change in mental statusCessation of any potential growth of the operated portion of the spineDeath
WARNINGS AND PRECAUTIONS
A device that has been implanted should never be reused or reprocessed under any circumstances. Sterile packaged devices should also never be resterilized. Reuse or eprocessing may compromise the structural integrity of these implants and create a risk of contamination of implants which could result in patient injury, illness, or death.
When used in deformity procedures, undersizing the implant may limit endplate engagement and potentially lead to implant migration and/or expulsion.
A successful result is not always achieved in every surgical case. This fact is especially true in spinal surgery where other patient conditions may compromise the results. Use of this product without autogenous bone and/or allograft bone graft comprised of cancellous and/or corticocancellous bone graft, and/or demineralized allograft bone with bone marrow aspirate or in cases that do not develop a union will not be successful.
Preoperative and operating procedures including knowledge of surgical techniques, good reduction, and correct selection and placement of implants are important considerations in the successful use of the system. Further, proper selection and compliance of the patient will greatly affect results. Patients who smoke were shown to have a reduced incidence of bone fusion. These patients should be advised of this fact and warned of this consequence. Obese, malnourished, or alcohol/drug abuse patients, and those with poor muscle and bone quality and nerve paralysis are also poor candidates for spinal fusion.
Patients with previous spinal surgery at the levels to be treated may have different clinical outcomes compared to those without a previous spinal surgery.
PHYSICIAN NOTE: Although the physician is the learned intermediary between the company and the patient, the important medical information in this document should be conveyed to the patient.

CAUTION: FEDERAL LAW (USA) RESTRICTS THESE DEVICES TO SALE BY OR ON THE ORDER OF A PHYSICIAN.
MRI INFORMATION
MR Conditional The Capstone™ Spinal System was determined to be MR-Conditional based on non-clinical testing and engineering rationales.
A patient with this device can be safely scanned immediately after device placement under the following conditions: Static Magnetic Field
Static magnetic field of 1.5 Tesla and 3.0 TeslaMaximum spatial gradient magnetic field of 3000-Gauss/cm (30 T/m) or lessMaximum whole body average specific absorption rate (SAR) of 2.0 -W/kg or less underNormal Operating Mode, for 15 minutes of scanning per pulse sequence
Under the scan conditions defined, a worst-case interbody fusion device representative of the Capstone™ Spinal System produced a maximum temperature rise of 4.4 °C after 15 minutes of continuous scanning.
In non-clinical testing, the image artifact caused by a worst-case interbody fusion device representative of the Capstone™ Spinal System extends approximately 20 mm from the device when imaged with a gradient echo pulse sequence in a 3.0 Tesla MR system. Therefore, optimization of MR imaging parameters to compensate for the presence of this device may be necessary.
If Capstone™ Spinal System is used in connection with any device which is not MR Conditional, please be advised that this combination has not been tested in the MR environment and, therefore, higher heating and possible injury to the patient may occur. The presence of other implants or the health state of the patient may require a modification of the MR conditions.
IMPLANT SELECTION
Selection of proper size, shape, and design of the implant for each patient is crucial to success of the procedure. Surgical implants are subject to repeated stresses in use, and their strength is limited by the need to adapt the design to the human anatomy. Unless great care is taken in patient selection, placement of the implant, and postoperative management to minimize stresses on the implant, such stresses may cause material fatigue and consequent breakage or loosening of the device before the fusion process is complete, which may result in further injury or the need to remove the device prematurely.
DEVICE FIXATION
Installation and positional adjustment of implants must only be done with special ancillary instruments and equipment supplied and designated by Medtronic. In the interests of patient safety, it is therefore recommended that Medtronic implants are not used with devices from any other source.
Never, under any circumstances, reuse a Capstone undamaged, it may have small defects or internal stress patterns that may lead to early breakage.
Spinal System device. Even when a removed device appears
PREOPERATIVE
Only patients that meet the criteria described in the indications should be selectedPatient conditions and predispositions such as those addressed in the contraindications should be avoidedCare should be taken when handling and storing the device(s). They should not be scratched or damaged. Devices should
be protected during storage especially from corrosive environments.
The surgeon should be familiar with the various devices before use and should personally verify all devices are present
before surgery.
The size of device for the case should be determined prior to surgery. An adequate inventory of implant sizes should be
available at the time of surgery including sizes larger and smaller than those expected to be used.
Unless supplied sterile, all devices should be cleaned and sterilized before use. Additional sterile components should be
available in case of any unexpected need.
INTRAOPERATIVE
Instructions in any available Capstone
Spinal System surgical technique manual should be carefully followed.
At all times, extreme caution should be used around the spinal cord and nerve roots. Damage to nerves will cause loss of
neurological functions.
Breakage, slippage, or misuse of instruments or implants may cause injury to the patient or operative personnelTo ensure proper fusion below and around the location of the fusion, autogenous bone and/or allograft bone graft
comprised of cancellous and/or corticocancellous bone graft, and/or demineralized allograft bone with bone marrow aspirate must be used
When used via a posterior approach, supplemental posterior instrumentation is recommended. Posterior supplemental
fixation is limited to Medtronic posterior instrumentation systems.
Bone cement should not be used because this material may make removal of these components difficult or impossible.
Heat generated from the curing process may damage or deform the PEEK devices.
POSTOPERATIVE
The physician’s postoperative directions and warnings to the patient, as well as the corresponding patient’s compliance are extremely important.
Detailed instructions on the use and limitations of the device should be given to the patient. The patient must be warned
that loosening and breakage of the device(s) are complications which may occur as result of early or excessive weight­bearing, muscular activity, or sudden jolts or shock to the spine.
The patient should be advised not to smoke or consume excess alcohol during period of the bone fusion processThe patient should 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 important that immobilization of union is established and confirmed by roentgenographic examination. If a non-union
develops or if the components loosen, migrate, or break, the devices should be revised and/or removed immediately before serious injury occurs.

Minimum dry times were validated using sterilizers having vacuum drying capabilities. Drying cycles using ambient atmospheric
pressure may require longer dry times. Refer to the sterilizer manufacturer’s recommendations. NOTE: Because of the many variables involved in sterilization, each medical facility should calibrate and verify the sterilization
process (e.g. temperatures, times) used for their equipment. The sterilization cycles listed in Table 2 are not considered by the FDA to be standard sterilization cycles. It is the user’s
responsibility to use only sterilizers and accessories (i.e. sterilization wraps, sterilization pouches, chemical indicators, biological indicators, and sterilization cassettes) cleared by the FDA for the selected sterilization cycle specifications (time and temperature).
