When used in conjunction with the CD HORIZON® Fenestrated Screws, KYPHON HV-R® Fenestrated Screw Cement is intended to restore the integrity of the spinal column even in the absence of fusion for a limited time period in patients with advanced stage tumors involving the thoracic and lumbar spine in whom life expectancy is of insufficient duration to permit achievement of fusion. KYPHON HV-R® Fenestrated Screw Cement is limited to use at spinal levels where the structural integrity of the spine is not severely compromised. When used in conjunction with KYPHON® HV-R Fenestrated Screw Cement, the CD HORIZON® Fenestrated Screws are intended to restore the integrity of the spinal column even in the absence of fusion for a limited time period in patients with advanced stage tumors involving the thoracic and lumbar spine in whom life expectancy is of insufficient duration to permit achievement of fusion. CD HORIZON® Fenestrated Screws augmented with KYPHON HV-R® Fenestrated Screw Cement are for use at spinal levels where the structural integrity of the spine is not severely compromised.

1) KYPHON HV-R® Fenestrated Screw Cement is self-curing PMMA based (high viscosity, radiopaque) bone cement. KYPHON HV-R® Fenestrated Screw Cement will be provided sterile in two components: 20 grams of powder and nine grams of liquid. The powder contains methylmethacrylate-styrene co-polymer, barium sulfate as a radiopacifier, and di-benzoyl peroxide as an initiator. This liquid contains methylmethacrylate monomer, N, N dimethyl-p-toluidine as a promoter and hydroquinone as a stabilizer. The powder and liquid components are mixed, in the provided liquid-to-powder proportions, into a homogenous paste, to initiate the polymerization reaction of monomer into polymer. 2) The CD HORIZON® Fenestrated Screw Set consists of a variety of cannulated multi-axial screws (MAS) with fenestrations offered in diameters ranging from 4.5mm to 10.5mm, with lengths ranging from 30-100mm based on CD HORIZON® LEGACY™ and CD HORIZON® SOLERA™ implants contained in the CD HORIZON® Spinal System. The CD HORIZON® Fenestrated Screws are specifically designed to connect to 4.75mm, 5.5mm, and 6.0mm diameter rods and associated connecting components contained within the CD HORIZON® Spinal System. The screws contain six fenestrations near the distal tip of the screw which provides a controlled means to deliver a small amount of polymethylmethacrylate (PMMA) bone cement into a targeted vertebral body. These screws are provided non-sterile.

The CD HORIZON® Growth Rod Conversion Set is indicated in patients with potential for additional spinal growth under 10 years of age who require surgical treatment to obtain and maintain correction of severe, progressive, life-threatening, early-onset spinal deformities associated with thoracic insufficiency including early-onset scoliosis. The CD HORIZON® Growth Rod Conversion Set may be used with any cleared traditional CD HORIZON® Spinal System rod construct ranging in diameter from 3.5mm to 5.5mm, with the exception of PEEK Rod constructs. The CD HORIZON® Growth Rod Conversion Set may not be used with PEEK Rods, SPIRE™ Spinous Process Plates, or Shape Memory Alloy (SMA) Staples.

The CD HORIZON® Growth Rod Conversion Set consists of a variety of connectors designed to convert a traditional fusion construct into a non-fusion growth enabling construct which can be surgically lengthened on a periodic basis as the patient grows. The CD HORIZON® Growth Rod Conversion Set components are manufactured from stainless steel or titanium alloy and are designed to interact with rod-based pedicle screw/hook constructs in which the rods range in diameter from 3.5mm to 5.5mm. The CD HORIZON® Growth Rod Conversion Set is specifically to be used with any traditional CD HORIZON® Spinal System (3.5mm) fusion construct cleared for pediatric usage. The CD HORIZON® Growth Rod Conversion Set may not be used with PEEK Rods, SPIRE® Spinous Process Plates and/or Shape Memory Alloy (SMA) Staples. The CD HORIZON® Growth Rod Conversion Set is limited to a posterior approach. The CD HORIZON® Growth Rod Conversion Set connectors are provided in both sterile and non-sterile form. The sterile implants are sterilized via gamma irradiation.
