Yes, I also was unaware of its existence… Until he informed me about the option of implanting a 5 cm nail in me. I discovered the detailed information on NuVasive, where they offer three variants of the nail for limb lengthening – 5cm, 6.5cm, and 8cm. However, I haven’t come across any mentions on the forum regarding the utilization of this shorter nail with a diameter of 10.7.
