Application
Ostim® is a ready-to-use, injectable bone matrix in paste form. It consists of 100% synthetic, nanoparticular, phase free hydroxylapatite.
Ostim® is used for filling in or reconstructing bone defects.
The Ostim® syringe in the double sterile pack can be used to apply paste to the bone defect directly or by means of applicators.
Ostim® does not harden off when mixed with blood or spongiosa, so it is highly suitable for increasing the volume of autologous or homologous material. The volume stability of Ostim® 35 enables it to resist bleeding pressure. Simultaneously, its viscosity enables it to be applied to form-fit in close contact with the bone.
Ostim® is suitable for making good defects in fractures in the spongy area. After repositioning the joint surfaces and mechanical stabilization, the defect is filled in with Ostim®.
Thanks to its paste-type properties, Ostim® is quickly converted into bone. New bone formation is visible after only three months.

Product Properties
Absorption
Ostim® has a nanocrystalline structure that makes it degradable in the organism.
Viscosity
Ostim® does not harden off and is therefore quickly absorbed by macrophages and osteoclasts. The defect is set in the customary way using the usual osteosynthesis measures.
Vascularization
Because of early vascularization, which is detectable after 7 to 10 days, cells can migrate into the Ostim® matrix, absorb it and form new bone in parallel with this.
Bone formation
Ostim® accelerates the rate at which bone-forming cells proliferate and stimulates bone healing. Bone builds up very rapidly. Ostim® is fully absorbed after just a few months and the defect has been completely and stably filled in by bone.
Building of load-bearing capacity
Depending on the osteosynthesis measures used, consistent mechanical stability is achieved and is no different from usual.
Indications:
Metaphyseal fractures and cysts
Acetabulum reconstruction and periprosthetic fractures during hip prosthesis exchange operations
Osteotomies
Filling cages in spinal column surgery
Combination with autogenous and allogenous spongiosa
Filling in defects in children
