Ebook: Bone modeling controlled by a nickel-titanium shape memory alloy intramedullary nail

Biomaterials.-Num 23 (2002).-pp 2535–2543.
Nitinol (NiTi) shape memory metal alloy makes it possible to prepare functional implants that apply a continuous bending force to the bone. The purpose of this study was to find out if bone modeling can be controlled with a functional intramedullary NiTi nail. Pre-shaped intramedullary NiTi nails (length 26 mm, thickness 1.0–1.4 mm) with a curvature radius of 25–37 mm were implanted in the cooled martensite form in the medullary cavity of the right femur in eight rats, where they restored their austenite form, causing a bending force.
