THE PRECICE INTRAMEDULLARY LIMB LENGTHENING SYSTEM – EARLY RESULTS

We present the results of a new non-invasive lengthening nail enabling accurate control of the lengthening process and joint rehabilitation.IntroductionThe use of intramedullary lengthening nails have gained popularity as they reduce common complications associated with external fixators, including infection, joint stiffness, bone regenerate deformity, late fracture and patient implant acceptance. Current nails however are associated with complications including implant breakage, mechanical failure, runaway nail and requiring MUA to restart or obtain segment lengthening. The Precice nail incorporates magnet technology with a hand held device allowing non-invasive lengthening. The nail is also reversible allowing shortening if required. Physiotherapy can continue throughout treatment to maintain joint range of motion without concern of uncontrolled nail runaway. The lengthening is axial reducing shear/torsional forces on the regenerate.MethodThe lengthening of 4 femora was undertaken in 3 patients, mean ag...
