OSferion60-Bone void filler-

Device Description

OSferion60 is a bone void filler which is composed of high purity beta-tricalcium phosphate.
In addition to the characteristics of OSferion (porosity 75%), OSferion60 increases the initial compression strength by reducing its porosity.
This improvement of initial compression strength enables OSferion60 to be press fitted to the defective parts.

Indications

OSferion is indicated to be gently packed or placed into bony voids or gaps of the skeletal system (i.e. the extremities spinc and pelvis.) that are not intrinsic to the stability of the bony structure. Following placement in the bony void or gap, the calcium phosphate scaffold resorbs and is replaced with bone during the healing process.
