A Comparison of the Device-Related Complications of Intramedullary Lengthening Nails Using a New Classification System

(a) “Rotation coupling” which is at the junction between telescoping rod (arrow head) is intact before lengthening. (b) Disconnection of rotation coupling is seen in PRECICE2 (arrow). Since it was not associated with instability, this was categorized as stability related problem (IIa). (c) Damaged rotation coupling is noticed in the retrieved PRECICE2 nail.
