Porous Titanium Granules Research Articles

Surgical treatment of depression fractures of the lateral tibial plateau using porous titanium granules

The clinical and radiological results were excellent in this pilot study of four cases of depression fracture of the lateral tibial plateau, where, in addition to internal fixation with screws or a buttress plate, porous titanium granules were used to support the elevated articular surface.

Porous Titanium Granules for Implant Stability and Bone Regeneration – a case followed for 12 years

The clinical and radiological results were excellent for each of the nine fixtures individually tested in a case followed for 12 years after implant treatment using split crest technique in combination with porous titanium granules for an augmentation of the dento-alveolar ridge in a severely resorbed maxilla.

Bone Ingrowth Through Porous Titanium Granulate Around a Femoral Stem

The procedure of using of porous titanium granules for cementless fixation of a hip replacement femoral stem was studied in a hemiarthroplasty model in 10 canines for 6 months. A vibrating instrument was used to facilitate both the delivery and distribution of the irregularly shaped porous titanium granules into the femoral canal as well as the subsequent insertion of a titanium alloy stem into the intramedullary bed of granules. Histological examination revealed lamellar bone formation through the mantle of porous titanium granules in continuity with the surrounding cortex resulting in the formation of an integrated mantle of bone and titanium granulate around the prosthesis.

Implantation of the Femoral Stem into a Bed of Titanium Granules Using Vibration

This study describes a new method for the fixation of titanium hip stem prostheses based on interdigitation of irregularly shaped porous titanium granules onto bone tissue. The granules were distributed into the prepared femoral cavity using a vibrating tool, and the stem was vibrated and tapped into the bed of granules. In this pilot study, 5 patients were followed between 9 and 15 years. The clinical results were excellent and the prostheses remained stable. Autopsy (one specimen) and computer tomography (three patients) show that the granules become incorporated by bone ingrowth.
