Limb Lengthening and Reconstruction

The Precice™ Intramedullary Limb Lengthening (IMLL) System is designed for limb lengthening, mal-unions, non-unions, or bone transport procedures. The innovative technology operates through a magnetic coupling with the implant and the handheld External Remote Controller (ERC) that can allow the nail to compress or distract depending on its application.

We aspire to enable surgeons to improve patients’ lives by making complex orthopedic reconstruction easier.

Precice™ is a proprietary technology that is adjustable from outside the body. This allows for constant changes at the time of implantation and over the course of treatment to accommodate the clinical needs of patients as they heal and grow. The technology is designed to give healthcare providers the ability to customize postoperative therapy for patients in a non-invasive manner using the External Remote Controller (ERC), reducing the need for further repeat surgical procedures, and promoting meaningful improvements in patient quality of life.

Clinical Benefits

The Precice™ Difference

Ease of Surgical Application

The same technique used to implant a standard trauma rod is used to implant Precice™^1,2

Cost Savings

There was less total cost for limb length discrepancy patients treated with Precice™ compared to the previous standard of care³

Intraoperative Patient Customization

The surgeon can customize the implant with the fast distractor and use locking pegs and partially threaded or fully threaded screws^1,2

Postoperative Patient Customization

The surgeon can customize the prescription for their patients with an External Remote Controller^1,2

Standard of Care

More than 15,000 patients have been treated with Precice™ since 2011

How It Works

Technology Benefits

The Precice™ system provides a customized, less invasive* approach to limb lengthening with benefits that include:

• Proprietary magnet technology
• Precision rate control
• Non-invasive postoperative adjustment through the ERC
• Customizable lengthening protocol based upon the patient’s prescription
• Up to 80mm of non-invasive distraction capability
• Available in three diameters (8.5, 10.7, and 12.5mm)
• Device is reversible

*As compared to treatment with an external fixator

State-of-the-Art Reconstruction Solutions

Precice™ Limb Lengthening System

The Precice™ IMLL System is an adjustable, state-of-the-art device that utilizes a remote control to non-invasively lengthen the femur or tibia with an ERC postoperatively. Interaction between magnets in the device and the ERC allows for precise, adjustable, and customizable distraction throughout the lengthening phase of treatment. Following the corticotomy and during the lengthening phase, the Precice™ implant is gradually lengthened externally with the handheld ERC based on patient requirements.

Plate Assisted Bone Segment Transport

Traditional bone transport treatment can be burdensome. Plate Assisted Bone Segment Transport (PABST) is a bone transport technique that combines the Precice™ nail with a locking plate to treat long bone defects, offering a simple, internal solution to treat segmental bone defects caused by a tumor or trauma.
