IMPLASPIN

The function of the osseoconductive spinal intervertebral disc is to prevent instability of the affected motion segment of the lumbar or cervical spine.

Osteoconductive implants, developed by the LASAK company, represent a new generation of biomaterials to replace bone tissue. The main characteristics of these implants are the excellent mechanical and significant osteoconductive properties of their surface, which enable faster and better healing of the implant. The implant is manufactured from pure titanium with a chemically treated surface or from PEEK-OPTIMA™ HA Enhanced with a roughened osteoconductive surface. The osteoconductive surface of the implant enables faster osseointegration without a soft tissue layer and helps to create a fusion between the implant and the bone. This strong fusion between the implant and the bone tissue ensures uniform distribution of stresses on the bone interface and loaded implant, thus preventing local overloading of the bone and subsequent bone resorption.

Indication

• Degenerative diseases of lumbar and cervical intervertebral discs

• Spinal cervical injuries

Osteoconductivity

The microstructure of an osteoconductive titanium assists the osteoblasts and osteocytes in the creation of new bone. The osteoconductive properties of the bioactive surface significantly enhance the creation of fusion between the bone and the implant.
Implants with an osteoconductive surface, compared to implants of pure titanium or PEEK show greater tolerance to unfavorable conditions for healing, such as a gap between the bone and the implant or primary implant instability.
