What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to evaluate the safety and effectiveness of surgeries for children with one leg shorter than the other. It compares two treatments: the Precice Intramedullary Limb Lengthening (IMLL) System and external fixator devices, both designed to lengthen the shorter leg. The trial targets children 12 years old and younger with a leg length difference of at least 2 cm due to birth conditions or other causes. As a Phase 2 trial, it measures the effectiveness of these treatments in an initial, smaller group of children, providing an opportunity to contribute to significant medical advancements.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What prior data suggests that these limb lengthening devices are safe for children?

Research has shown that the Precice Intramedullary Limb Lengthening (IMLL) System is generally well-received by patients. It has been used in over 1,000 cases worldwide, with more than 250 cases reporting excellent results. Patients often experience less pain and encounter fewer problems compared to older methods. This system also requires fewer surgeries, which is a significant advantage.

External fixator devices offer another safe and effective way to correct limb length differences in children. They allow gradual limb lengthening, which can lead to good results. These devices have been successfully used in children, proving reliable for managing moderate limb length differences.

Both treatments have strong safety records, making them good options for those considering limb lengthening procedures.12345

Why are researchers excited about this trial's treatments?

The Precice Intramedullary Limb Lengthening (IMLL) System is unique because it offers a less invasive option for correcting limb length discrepancies in children. Unlike traditional methods like external fixators, which require hardware to be attached outside the body and often involve discomfort and a higher risk of infection, the Precice system is implanted inside the bone. This internal approach allows for more precise control over the lengthening process and a more streamlined recovery, making it a promising alternative for young patients needing limb correction. Researchers are excited because it could potentially reduce complications and improve quality of life compared to existing treatments.

What evidence suggests that the Precice IMLL System and external fixator devices are effective for limb length discrepancy?

Research has shown that the Precice Intramedullary Limb Lengthening (IMLL) System, one of the treatments in this trial, effectively lengthens limbs. It has been used in over 1,000 cases worldwide, with more than 250 published cases demonstrating excellent results. Specifically, these results include less pain and fewer complications compared to older methods. Patients using Precice have required fewer surgeries than those with previous standard treatments. The External Fixator, another treatment option in this trial, also effectively corrects differences in limb length. It can adjust both limb length and shape simultaneously, making it a reliable choice. Both methods have successfully achieved the desired limb length in various studies.23678
