REMOTE CONTROL TECHNOLOGY FOR THE TREATMENT OF LIMB LENGTH DISCREPANCIES
The PRECICE system is an intramedullary nail used for limb lengthening of the femur and tibia that utilizes an External Remote Controller (ERC) to non-invasively lengthen the implant. The key to the technology is the magnetic interaction between the PRECICE implant and the PRECICE ERC, a portable, hand-held unit that lengthens the PRECICE implant. The PRECICE system is used to treat lower limb length discrepancies, often the result of acute or chronic fractures.
- Proprietary magnet technology
- Precision rate control
- Non-invasive adjustment via external remote controller
- Customizable lengthening protocol based upon patient’s prescription
- Up to 80mm of non-invasive distraction capability
- Available in three diameters (8.5mm, 10.7mm, and 12.5mm)
- Device is reversible
How the PRECICE System Works
The key to the platform technology is the magnetic interaction between the PRECICE implant and the PRECICE ERC. Permanent magnets are used to non-invasively adjust the PRECICE implant. This advancement in intramedullary limb lengthening allows for a precise, controlled lengthening phase with the ability to shorten the device if necessary.

The PRECICE Intramedullary Limb Lengthening (IMLL) System is composed of an implantable intramedullary nail, locking screws, reusable instruments, and a hand-held External Remote Controller (ERC). The PRECICE nail is a sterile single use device that is surgically implanted using the instruments and locking screws. The ERC is used daily after implantation to non-invasively lengthen or shorten the implant to a prescribed length. The PRECICE System is intended for limb lengthening of the femur and tibia. Contraindications include infection or pathologic conditions of bone such as osteopenia which would impair the ability to securely fix the device, metal allergies and sensitivities, patients whose distance from the surface of the treated limb to the intramedullary canal is greater than 51 mm for the 10.7 and 12.5 mm diameter implants or greater than 38 mm for the 8.5 mm diameter implant, patients with an irregular bone diameter that would prevent insertion of the PRECICE nail, patients in which the PRECICE nail would cross joint spaces or open epiphyseal growth plates, patients in which there is an obliterated medullary canal or other conditions that tend to retard healing such as blood supply limitations, peripheral vascular disease or evidence of inadequate vascularity, patients unwilling or incapable of following postoperative care instructions, patients weighing in excess of 114 Kg for the 10.7 and 12.5 mm diameter implants (models A-G, H, J, K, and U) or weighing in excess of 57 Kg for the 8.5 and 10.7 mm diameter implants models (A-G, H, J, K, U, N, M ,P, and Q). The implantable device is only to be used by a trained licensed physician. Please refer to the PRECICE IMLL System instructions for use for complete Important Safety Information. Caution: Federal law restricts this device to sale by or on the order of a physician.
