## Intended Use

Wright Plaster of Paris Pellets are intended to be gently packed into non-loadbearing long bone voids. These bone voids may be surgically created osseous defects or osseous defects created from traumatic injury to the bone. The Wright Plaster of Paris Pellets provide a bone filler that resorbs and is replaced with bone during the healing process.

## Device Story

Biodegradable, radiopaque calcium sulfate dihydrate pellets; used as bone void filler; packed into non-loadbearing long bone defects; resorbed in 30-60 days; replaced by bone during healing; sterile, single-patient use; 0.1g per pellet; supplied in 100-count pouches.

## Clinical Evidence

Bench testing only; dissolution studies demonstrate equivalent dissolution rates to predicate device.

## Technological Characteristics

Composition: 98% medical grade calcium dihydrate (CaSO4 • 2H2O), 2% stearic acid; form factor: 0.1g pellets; sterile; biodegradable; radiopaque.

## Regulatory 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.
