Intended Use

DSM Biomedical Calcium Phosphate Cement with Microspheres is indicated to fill bony voids or gaps of the sketal system (i.e. extremities and pelvis). These defects may be surgically created or osseous defects created from traumatic injury to the bone. The Calcium Phosphate Cement with Microspheres is indicated only for bony voids or gaps that are not intrinsic to the stability of the bony structure. The Calcium Phosphate Cement with Microspheres cured in situ provides an open void/gap filler that can augment provisional hardware (e.g. K-Wires, plates, screws) to help support bone fragments during the surgical procedure. The cured cement acts only as a temporary support media and is not intended to provide structural support during the healing process. The Calcium Phosphate Cement with Microspheres resorbs and is replaced by bone during the healing process.

Device Story

Injectable, fast-setting bone void filler; composed of calcium phosphate, bovine collagen, and PLGA microspheres. Supplied as powder in mixing syringe; mixed with saline, patient blood, or bone marrow. Used by surgeons in clinical settings to fill non-structural bony voids or gaps in extremities and pelvis; augments provisional hardware (plates, screws, K-wires) during procedures. Cures in situ to form hydroxyapatite; resorbs over time and is replaced by bone. Provides temporary support; not intended for permanent structural load-bearing. Sterile, single-use device.

Clinical Evidence

Bench testing performed per FDA guidance and ASTM F1185. Biocompatibility testing conducted per ISO 10993-1 (cytotoxicity, sensitization, irritation, systemic toxicity, genotoxicity, hemocompatibility, subacute toxicity, implantation). Includes viral inactivation study and residual chemical assessment. Ovine bilateral femoral defect animal study compared bone healing performance against predicate. Results indicate acceptable biocompatibility and performance profile.

Technological Characteristics

Calcium phosphate powder with bovine collagen and PLGA microspheres; converts to hydroxyapatite in vivo. Injectable, sculptable, fast-setting. Supplied sterile via gamma irradiation (SAL 10^-6). Complies with ASTM F1185 for hydroxylapatite. Single-use, non-pyrogenic.

Indications for Use

Indicated for filling bony voids or gaps in the skeletal system (extremities and pelvis) caused by surgery or traumatic injury. Not for use in defects intrinsic to bony structure stability. Used as temporary support media to augment provisional hardware (K-wires, plates, screws).

#### Device Description

DSM Biomedical Calcium Phosphate Cement with Microspheres is an injectable, fast self-setting bone substitute. DSM Biomedical Calcium Phosphate Cement with Microspheres is composed of calcium phosphate which converts to hydroxyapatite in vivo, bovine collagen powder, and PLGA microspheres. The device can also be used to augment provisional hardware to help support bone fragments during the surgical procedure. The cement is provided in a powder form packaged in a mixing syringe. The mixing syringe allows for the combination of saline, the patient's blood, or the patient's bone marrow at the required powder-to-liquid ratio. DSM Biomedical Calcium Phosphate Cement with Microspheres is supplied sterile by gamma irradiation and is non-pyrogenic.

#### Indications For Use:

DSM Biomedical Calcium Phosphate Cement with Microspheres is indicated to fill bony voids or gaps of the skeletal system (i.e. extremities and pelvis). These defects may be surgically created or osseous defects created from traumatic injury to the bone. The Calcium Phosphate Cement with Microspheres is indicated only for bony voids or gaps that are not intrinsic to the stability of the bony structure. The Calcium Phosphate Cement with Microspheres cured in situ provides an open void/gap filler that can augment provisional hardware (e.g. K-Wires, plates, screws) to help support bone fragments during the surgical procedure. The cured cement acts only as a temporary support media and is not intended to provide structural support during the healing process. The Calcium Phosphate Cement with Microspheres resorbs and is replaced by bone during the healing process.

#### Basis for Substantial Equivalence:

The DSM Biomedical Calcium Phosphate Cement with Microspheres is substantially equivalent in terms of indications for use, material composition, technological characteristics and performance characteristics to that of the predicate device, Stryker® Injectable Cement (K060061).

DSM Biomedical Calcium Phosphate Cement with Microspheres and the predicate device have comparable indications for use. Both are calcium phosphate powders that when mixing liquid form a fast setting cement. The addition of the collagen and PLGA to the subject device does not raise questions of substantial equivalence as the safety of the materials has been shown through biocompatibility, bench top testing, an animal study, and a viral inactivation study. The subject and predicate devices are both injectable, sculptable, and fast setting calcium phosphate cement that converts to hydroxyapatite over time. Both the subject and predicate devices are packaged with accessories to aid in the mixing and delivery of the cement. The subject and predicate devices are provided sterile and are for single use only. The subject and predicate devices are biocompatible and non-pyrogenic.

performance characteristics and biological safety of DSM Biomedical Calcium Phosphate Cement with Microspheres.

Material characterization and performance testing of the DSM Biomedical Calcium Phosphate Cement with Microspheres was completed in accordance with the FDA Guidance Document, Resorbable Calcium Salt Bone Void Filler Device and ASTM F1185 Standard Specification of Hydroxylapatite for Surgical Implants.

An ovine bilateral femoral defect animal study was performed to evaluate bone healing following treatment with the DSM Biomedical Calcium Phosphate Cement with Microspheres compared to the predicate device.

Biocompatibility testing was completed in accordance with the requirements of ISO 10993-1: 2009, Biological Evaluation of Medical Devices-Part 1: Evaluation and Testing within a Risk Management Process for a permanent implant device with tissue/bone contact. Testing included cytotoxicity, sensitization, irritation, acute systemic toxicity, genotoxicity, hemocompatibility, subacute toxicity, and implantation. Other safety testing included a viral inactivation study and residual chemical assessment. Results indicate that the device's biocompatibility profile is acceptable.

#### Substantial Equivalence:

DSM Biomedical Calcium Phosphate Cement with Microspheres has the same intended use and similar indications, technological characteristics, and principles of operation as the predicate device. The minor technological differences that exist between the DSM Biomedical Calcium Phosphate Cement with Microspheres do not raise any new issues of safety and effectiveness. The bench, animal, and biocompatibility testing demonstrates that DSM Biomedical Calcium Phosphate Cement with Microspheres is substantially equivalent to the predicate device.

## Conclusion:

The DSM Biomedical Calcium Phosphate Cement with Microspheres is substantially equivalent in terms of indications for use, material composition, technological characteristics, and performance characteristics to the predicate device, Stryker® Injectable Cement (K060061) [Stryker® CMF].
