## Indications for use
si-Mochi is an implant intended to fill bony voids or gaps of the skeletal system (i.e.extremities, pelvis). These osseous defects may be surgically created or the result of traumatic injury to the bone and are not intrinsic to the stability of the bony structure. si-Mochi resorbs and is replaced with bone during the healing process.
