## Indications for Use

Callos CMF Bone Void Filler is a calcium phosphate bone void filler indicated for the repair or filling of neurosurgical burr holes, other craniofacial defects and craniotomy cuts with a surface area no larger than 25cm². Callos CMF Bone Void Filler may be used in the restoration or augmentation of bony contours of the craniofacial skeleton, including frontoorbital, malar, and mental areas.

## Device Story

Callos CMF Bone Void Filler is an impactable, moldable, single-use, biocompatible calcium phosphate cement. It is used by surgeons to fill or repair neurosurgical burr holes, craniotomy cuts, and craniofacial defects, or to augment bony contours. The material is designed to remodel and be replaced by natural bone during the healing process. It is supplied in kit sizes of 3cc, 5cc, and 10cc. The device is applied directly to the defect site by the clinician to restore skeletal structure.

## Clinical Evidence

Bench testing only.

## Technological Characteristics

Biocompatible calcium phosphate bone void filler; impactable and moldable consistency; single-use; supplied in 3cc, 5cc, and 10cc kits; designed for in-vivo remodeling and replacement by bone.

## Regulatory 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.
