Betzbone
BETZBONE Intramedullary Lengthening Nail
A proprietary German weight-bearing internal nail with the highest stated stability and length capacity (up to ~12 cm) — offered by the Becker-Betz Institute.
How it works
BETZBONE is a proprietary internal lengthening nail developed by Prof. Betz and offered at the Becker-Betz Institute in Freiburg, Germany. It is a weight-bearing internal nail in the Albizzia family; per the manufacturer it uses an internal motor powered by an external transmitter applied through the skin. Its marketed distinction is the highest stability and lengthening capacity of current intramedullary nails — up to about 12 cm — allowing full weight-bearing and unlimited physiotherapy immediately after surgery. Because it is a single-center proprietary device, independent long-term data is limited compared with PRECICE.
