Intended Use

Vitoss Bioactive Foam Bone Graft Substitute is intended for use as a bone void filler for voids or gaps that are not intrinsic to the stability of the bony structure. Vitoss Bioactive Foam is indicated for use in the treatment of surgically created osseous defects or osseous defects created from traumatic injury to the bone. Vitoss Bioactive Foam should not be used to treat large defects that in the surgeon's opinion would fail to heal spontaneously. Vitoss Bioactive Foam Bone Graft Substitute is intended to be used for filling bony voids or gaps of the skeletal system (i.e., the extremities, spine and pelvis). Following placement in the bony void or gap, the scaffold resorbs and is replaced with bone during the healing process.

Device Story

Resorbable, osteoconductive bone graft substitute; trabecular structure mimics human cancellous bone. Implanted by surgeons into non-structural bony voids or gaps in extremities, spine, or pelvis. Scaffold resorbs over time, replaced by natural bone. Osteostimulatory properties demonstrated via in-vitro calcium phosphate formation in simulated body fluid. Used in clinical settings for bone defect management.

Clinical Evidence

Bench testing only. In-vitro studies demonstrated osteostimulatory activity via calcium phosphate formation on the device surface after exposure to simulated body fluid; no human clinical data provided.

Technological Characteristics

Resorbable, osteoconductive implant; trabecular structure with multidirectional interconnected porosity. Material composition includes bioactive glass component. Form factor is a foam strip.

Indications for Use

Indicated for filling non-structural bony voids or gaps in the skeletal system (extremities, spine, pelvis) resulting from surgical procedures or traumatic injury. Contraindicated for large defects that would not heal spontaneously.

Regulatory Classification

Identification

A resorbable calcium salt bone void filler device is a resorbable implant intended to fill bony voids or gaps of the extremities, spine, and pelvis that are caused by trauma or surgery and are not intrinsic to the stability of the bony structure.

Special Controls

*Classification.* Class II (special controls). The special control for this device is the FDA guidance document entitled “Class II Special Controls Guidance: Resorbable Calcium Salt Bone Void Filler Device; Guidance for Industry and FDA.” See § 888.1(e) of this chapter for the availability of this guidance.

# Intended Use / Indications for Use

Vitoss® Bioactive Foam Bone Graft Substitute is labeled with the following Intended Use statement:

{1}------------------------------------------------

Vitoss Bioactive Foam Bone Graft Substitute is intended for use as a bone void v thoss Dioactive I vann that are not intrinsic to the stability of the bony structure. ffiter for volus of gaps that area for use in the treatment of surgically created v tross Droactive Fount is marcants created from traumatic injury to the bone. osseous derects of own should not be used to treat large defects that in the surgeon's opinion would fail to heal spontaneously.

Vitoss Bioactive Foam Bone Graft Substitute is intended to be used for filling bony voids or gaps of the skeletal system (i.e., the extremities, spine and pelvis). Following placement in the bony void or gap, the scaffold resorbs and is replaced with bone during the healing process.

# Technological Characteristics

Vitoss Bioactive Foam is a resorbable, osteoconductive implant with a trabecular structure that resembles the multidirectional interconnected porosity of human cancellous bone.

### Performance Data

Performance testing was conducted to ensure that Vitoss Bioactive Foam met its design r orrormative sond performed in a manner substantially similar to the predicate devices. In all instances, Vitoss Bioactive Foam functioned as intended.

Vitoss Bioactive Foam is osteostimulatory based on in-vitro studies in which calcium phosphate growth was induced on the surface of the Vitoss Bioactive Foam after exposure to simulated body fluid. The Vitoss Bioactive Foam strips had widespread calcium phosphate formation by 3 days. This phenomenon was not observed in control samples in which there was no bioactive glass component. The osteostimulatory nature of Vitoss Bioactive Foam has not been correlated to human clinical experience.

### Substantial Equivalence

Vitoss Bioactive Foam is as safe and effective as its predicates. Vitoss Bioactive Foam has the same intended uses and similar indications, technological characteristics, and principles of operation as its predicate devices. The minor differences between Vitoss Bioactive Foam and its predicate devices raise no new issues of safety or effectiveness. Performance data demonstrate that Vitoss Bioactive Foam is as safe and effective as its predicate devices. Thus, Vitoss Bioactive Foam is substantially equivalent.
