Polymeric bone implants with shape memory with the bone graft installation

Polymeric bone implants with shape memory.

 

 

Polymeric bone implants with shape memory are made of polymeric material-based composite polylactide – polymer of lactic acid. Feature polymer implant with shape memory is that it can be compressed in 2 times from mechanical impact and to “unfold” under the influence of a certain temperature in the process of surgery. The polymeric material of the implant is bioresorbable.

Technology is in the process of development and testing!

Description:

Polymeric bone implants with shape memory are made of polymeric material-based composite polylactide – polymer of lactic acid. Feature polymer implant with shape memory is that it can be compressed in 2 times from mechanical impact and to “unfold” under the influence of a certain temperature in the process of surgery. Such polymeric bone implants are applied without fasteners and fixers to process the transaction.

Thus, the implant can be printed on a 3D printer at the specified dimensions, squeeze twice, and in the process of operation, to heat and to a fragment of the original form is securely fixed in the area of bone tissue, without the use of metal fasteners and clamps traditionally used in grafting.

For implants with shape memory characteristic increased the survival rate in the tissues of the body, as well as the ability to dissolve, and subsequently replaced by natural bone tissue. This is made possible by the fact that simultaneously with the implant developed and applied a technology of settling of the implant multipotent mesenchymal stromal cells (MSC) isolated from bone marrow of the patient that stimulates the formation of blood vessels and tissue inside of the implant, optimizing the process of survival and increasing the efficiency of transplantation.

The polymer implant has a given geometry and high porosity, does not require additional processing, is tightly fixed in the bone defect. In addition, the polymeric material of the implant is bioresorbable in the body, it decomposes harmlessly.

 


Advantages:

– increased survival rate in the tissues of the body

the ability to dissolve and be replaced with natural tissue,

– set geometry and high porosity,

does not require additional processing

– tightly fixed in the bone defect without fasteners and fixers,

decompose in the body, does not cause him any harm.
