The Precise Nail, specifically the Precise 2.2, a magnetically actuated lengthening nail. I’d like to walk you through how we physically lengthen the bone after surgery using this device. During the procedure, the nail is implanted at the same time the bone is cut, or osteotomized. From that point, the body begins healing the osteotomy by forming new bone and blood clots, initiating the recovery process.
After about 10 to 14 days, I’ll teach you how to lengthen the nail. Although you can’t see them, the nail contains rare earth magnets attached to a small gearbox. By spinning these magnets, we activate the gearbox and gradually elongate the nail, allowing the bone to lengthen in a controlled manner.

This process begins while you’re still in the hospital under my care, ensuring you learn how to use the machine correctly. The device we use for this is called the ERC (External Remote Controller), and while it might look bulky, almost like something from the Cold War era—it’s simple and effective. The ERC generates a magnetic field that alternates polarity, spinning the magnet inside the nail, which, in turn, lengthens it.
Though the ERC may seem intimidating at first, it’s actually very user-friendly. I take great pride in personally teaching you how to use it, as I believe I’m one of the few surgeons who does this directly. It’s important to me that you feel confident in the process.
The nail will elongate at a precise rate, typically between 0.75 to 1 mm per day, which we’ve found to be the ideal pace for producing strong, healthy bone. Throughout the lengthening process, I’ll see you every two weeks for x-rays and clinical check-ups to monitor the bone’s progress and ensure everything is on track. We’ll also ensure that the surrounding soft tissues, blood vessels, nerves, and joints are keeping pace with the bone growth.
This method ensures that we perform the lengthening safely, combining advanced technology with meticulous clinical care and follow-up.
