Indications for Use

NovaBone-AR is indicated only for bony voids or gaps that are not intrinsic to the stability of the bony structure. NovaBone-AR is indicated to be gently packed into bony voids or gaps of the skeletal system (i.e. the extremities, spine and pelvis). These defects may be surgically created osseous defects or osseous defects created from traumatic injury to the bone. The product provides a bone void filler that resorbs and is replaced with bone during the healing process.

Device Story

NovaBone-AR is a synthetic, resorbable, osteoconductive bone void filler; composed of two calcium-phosphorus-silicate bioactive glass materials (melt-derived Bioglass and sol-gel derived glass). Particulate form; packed into osseous defects by clinicians during surgery. Sol-gel component resorbs more rapidly than melt-derived component; creates space for tissue infiltration and host bone replacement. Non-structural; requires internal/external fixation for stability. Benefits include scaffold for natural bone regeneration; resorption within six months. Used in clinical settings by surgeons familiar with bone grafting.

Clinical Evidence

No clinical data. Evidence consists of in vivo performance data comparing NovaBone-AR and its individual sol-gel component to the predicate, supplemented by in vitro testing.

Technological Characteristics

Particulate, synthetic, inorganic, biocompatible, osteoconductive bone void filler. Composed of melt-derived calcium-phosphorus-sodium-silicate (Bioglass) and sol-gel derived calcium-phosphorus-silicate glass. Non-structural scaffold. Resorbable within six months.

Indications for Use

Indicated for patients with non-structural bony voids or gaps in the skeletal system (extremities, spine, pelvis) resulting from surgery or traumatic injury. Contraindicated for load-bearing defects requiring structural support.

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

#### 4. Device Description

NovaBone-AR is a synthetic resorbable osteoconductive bone graft substitute particulate composed of two similar calcium phospho-silicate bioactive glass materials. The major component is a melt-derived calcium-phosphorus-sodiumsilicate (Bioglass) designed specifically for its absorbability and ostcoconductive nature. The second component is a calcium-phosphorus-silicate bioactive glass, chemically similar to the major component, but derived via a solution-gelation (sol-gel) process. The secondary sol-gel component is more rapidly absorbed from the graft site than the standard melt-derived component, opening additional space between the Bioglass particles for tissue infiltration and replacement by host bonc during the healing process.

#### Intended Use న్.

NovaBone-AR is indicated only for bony voids or gaps that are not intrinsic to the stability of the bony structure. NovaBone-AR is indicated to be gently packed into bony voids or gaps of the skeletal system (i.e. the extremities, spine and pelvis).

> These defects may be surgically created osseous defects or osseous defects created from traumatic injury to the bone. The product provides a bone void filler that resorbs and is replaced with bone during the healing process.

#### Technological Characteristics 6.

The technological characteristics of NovaBone-AR and the predicate devices NovaBone and NovaBone-BBG are similar. All are designed to be osteoconductive space-filling particulates to be gently packed into defect sites and to be used as a non-structural scaffold for the body's natural healing and bone regeneration process. To meet this design, the three devices are similar in nature, all being particulate, synthetic, inorganic, biocompatible and osteoconductive materials.

The main technological difference between NovaBone-AR and the NovaBone predicate is that while the predicate NovaBonc is a single-material Bioglass devices, the NovaBone-AR contains Bioglass and a second sol-gel derived bioactive glass composition. The sol-gel glass is composed of calcium, phosphorus, and silicon, similar to the Bioglass component, but without the sodium. This two-component NovaBone-AR is identical to the NovaBone-BBG predicate, the NovaBone-BBG being cleared for different indications.

For all three devices, the materials are substantially absorbed within the six-month timeframe normally associated with bone remodeling, the devices being replaced by new bone tissue. The sol-gel phase of the NovaBone-AR and the NovaBone-BBG predicate is more soluble than the standard melt-derived Bioglass, permitting a more rapid initial absorption and therefore providing more space for bone infiltration at an earlier period than for the predicates.

In vivo performance data comparing NovaBone-AR and/or the individual sol-gel component to NovaBone are summarized.

# Warnings and Precautions 7.

NovaBone-AR does not possess sufficient mechanical strength to support load bearing defects prior to hard tissue ingrowth. In cases of fracture fixation or where load support is required, standard internal or external stabilization techniques must be followed to obtain rigid stabilization in all planes.

NovaBone-AR is intended for use by clinician familiar with bone grafting and internal/external fixation techniques. NovaBone-AR must not be used to gain screw purchase or to stabilize screw placement.

# Complications 8.

Possible complications are the same as to be expected of autogenous bone grafting procedures. These may include: superficial wound infection, deep wound infection, deep wound infection with osteomyelitis, delayed union, loss of reduction, failure of fusion, loss of bone graft, graft protrusion and / or dislodgement, and general complications that may arise from ancsthesia and / or surgery.

# 9. Conclusion

NovaBone-AR is claimed to be substantially equivalent to the NovaBone and NovaBone-BBG predicates as a non-structural osteoconductive bone void filler for osseous defects. Side-by-side comparative in vivo performance data were presented. Additional supporting in vitro data were supplied.
