IMPORTANT INFORMATION ON THE CLYDESDALE™ SPINAL SYSTEM
PURPOSE
This device is a PEEK (POLYETHERETHERKETONE) interbody fusion device intended for stabilization and to promote bone
fusion during the normal healing process following surgical correction of disorders of the spine. The product should be implanted
only by a physician thoroughly knowledgeable in the implant’s material and surgical aspects and instructed as to its mechanical
and material applications and limitations.
DESCRIPTION
The Clydesdale™ Spinal System consists of PEEK cages of various widths and heights, which include Tantalum markers.
These devices 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.
Implied warranties of merchantability and fitness for a particular purpose or use are specifically excluded.
INDICATIONS
The Clydesdale™ Spinal System is designed 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 to facilitate
interbody fusion and is intended for use with supplemental fixation systems cleared for use in the lumbar spine. The
Clydesdale™ Spinal System is used for patients diagnosed with degenerative disc disease (DDD) at one or two contiguous
levels from L2 to S1. These 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. These
patients should be skeletally mature and have had six months of non-operative treatment. These implants may be implanted via
a minimally invasive lateral approach.
CONTRAINDICATIONS
This device is not intended for cervical spine use.

▪ Change in mental status.
▪ Cessation of any potential growth of the operated portion of the spine.
▪ Death.
WARNINGS AND PRECAUTIONS
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 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, and/or alcohol/
drug abuse patients and those with poor muscle and bone quality and/or 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.
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 reprocessing may compromise the structural integrity of these implants and create a
risk of contamination of the implants which could result in patient injury, illness, or death.
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.
FOR US AUDIENCES ONLY
Caution: Federal law (USA) restricts these devices to sale by or on the order of a physician.
MRI INFORMATION
The Clydesdale™ Spinal System has not been evaluated for safety and compatibility in the MR environment. It has not been
tested for heating, migration, or image artifact in the MR environment. The safety of the Clydesdale™ Spinal System in the MR
environment is unknown. Scanning a patient who has this device may result in patient injury.
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 Clydesdale
undamaged, it may have small defects or internal stress patterns that may lead to early breakage.

PREOPERATIVE
▪ Only patients that meet the criteria described in the indications should be selected.
▪ Patient conditions and/or predispositions such as those addressed in the contraindications should be avoided.
▪ Care should be taken when handling and storing of 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
▪ The instructions in any available Clydesdale
™
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 function.
▪ Breakage, slippage, or misuse of instruments or implants may cause injury to the patient or operative personnel.
▪ To 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.
▪ 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 and the corresponding patient compliance are extremely
important.
▪ Detailed instructions on use and limitations of the device should 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 weightbearing, muscular activity, or sudden jolts or shock to the spine.
▪ The patient should be advised not to smoke or consume excess alcohol during the period of the bone fusion process.
▪ The 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 components loosen, migrate, and/or break, 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, exposure times) used for their equipment.
The sterilization cycles listed in Table 2 are not considered by the Food and Drug Administration (FDA) to be standard
sterilization cycles. It is the user’s responsibility to use only sterilizers and accessories (e.g. sterilization wraps, sterilization
pouches, chemical indicators, biological indicators, and sterilization cassettes) cleared by the FDA for the selected sterilization
cycle specifications (time and temperature).
