Indications for Use
OsteoVation Impact is a calcium phosphate bone void filler indicated for the repair or filling of neurosurgical burr holes, other cranialbone defects and craniotomy cuts with a surface area no larger than 25cm2. OsteoVation Impact may be used in the restoration or augmentation of bony contours of the cranialbone skeleton.
Device Story
OsteoVation Impact is a self-setting, biocompatible calcium phosphate bone void filler. It consists of two components: a powder (calcium phosphate, carboxymethylcellulose) and a liquid (sodium phosphate, sodium silicate), which are mixed by the user using an included bowl, pestle, and spatula. The resulting paste is moldable and impactable, intended for application by a surgeon to fill cranial defects or augment bone contours. The device is supplied in sterile convenience kits and sterilized via gamma radiation. It is a passive implantable material; it does not involve electronic processing, software, or clinical decision-support algorithms. The device provides a structural scaffold for bone repair.
Clinical Evidence
No clinical studies were performed. Substantial equivalence is supported by bench testing, including working time, setting strength, tensile strength, temperature profile, pH profile, FTIR analysis, and crystallographic analysis (XRD).
Technological Characteristics
Calcium phosphate bone void filler; self-setting paste. Components: calcium phosphate, sodium phosphate (SPMA), carboxymethylcellulose, sodium silicate. Sterilization: Gamma radiation (25-50 kGy; SAL 10^-9). Form factor: 3cc, 5cc, 10cc convenience kits. No energy source, no connectivity, no software.
Indications for Use
Indicated for repair or filling of neurosurgical burr holes, cranial bone defects, and craniotomy cuts (surface area ≤ 25cm2) and restoration/augmentation of cranial bone contours.
Regulatory Classification
Identification
Methyl methacrylate for cranioplasty (skull repair) is a self-curing acrylic that a surgeon uses to repair a skull defect in a patient. At the time of surgery, the surgeon initiates polymerization of the material and forms it into a plate or other appropriate shape to repair the defect.

#### IV. DEVICE DESCRIPTION
OsteoVation Impact is a self-setting, calcium phosphate bone void filler designed for single use and biocompatible. Osteo Vation Impact is an impactable (moldable) calcium phosphate.
OsteoVation Impact is comprised of two working components: a calcium phosphate, a sodium phosphate (SPMA), carboxymethylcellulose powder, a sodium silicate, sodium phosphate (SPMA) solution, and a mixing system (mixing bowl, pestle and spatula). The two working components are packaged separately and are to be mixed together by the end user prior to implantation.

OsteoVation Impact is offered in 3cc, 5cc, and 10cc sterile convenience kits. Each kit includes the two working components in combination with a mixing bowl, pestle, and spatula. It is sterilized using gamma radiation with a minimum dose of 25 kGy and a maximum dose of 50 kGy with a Sterility Assurance Level of 10-9.
#### INDICATIONS FOR USE V.
OsteoVation Impact is a calcium phosphate bone void filler indicated for the repair or filling of neurosurgical burr holes, other cranialbone defects and craniotomy cuts with a surface area no larger than 25cm2. OsteoVation Impact may be used in the restoration or augmentation of bony contours of the cranialbone skeleton.
#### COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH VI. THE PREDICATE DEVICE
The subject and predicate devices are classified as Methyl Methacrylate for Cranioplasty, and are intended for use in cranialbone applications. In establishing substantial equivalence to the predicate device, Skeletal Kinetics, LLC evaluated the indications for use, materials, technology, and product specifications of those products. Additionally, performance testing has been completed to demonstrate that the Osteo Vation Impact as a bone void filler in cranialbone applications is as safe, and effective, and performs as well as the legally marketed device. The performance testing and device comparison did not raise issues of safety or efficacy.
A formulation change is being made to the powder and liquid working components of the subject device in order optimize the utility of the device during implantation. Sodium phosphate (SPMA) is being added to the liquid component along with a ratio change. A ratio change is also being made to the powder component. This formulation change increases the room temperature range for the utility of the paste from 19℃ - 21℃ to 19℃ - 25℃. Verification testing of the working and setting time shows the formulation change does not affect the performance characteristics of the bone void filler.
The following technological differences exist between the subject and predicate device:
- Increase in room temperature range in Instructions for Use from 19°C -● 21°C to 19°C = 25°C
- Addition of sodium phosphate (SPMA) to liquid component ●
- Ratio change to powder component ●

#### CONCLUSIONS VIII.
The indication for use, technological characteristics, materials, technology, and product specifications are equivalent. The performance testing conducted, demonstrate that the OsteoVation Impact as a bone void filler in cranialbone applications is as safe, and effective, and performs as well as the legally marketed device and did not raise new issues of safety or efficacy.
Differences in the subject and predicate device formulation change increases the room temperature range for the utility of the paste. Verification testing of the working and setting time shows the formulation change does not affect the performance characteristics of the bone void filler
Additional non-clinical evaluations (tensile strength, temperature profile, pH profile, FTIR analysis, crystallographic analysis) demonstrate comparable results as the test performed for the predicate device.
The conclusions drawn from the nonclinical demonstrate that the device is as safe, and effective, and performs as well as the legally marketed device.
