Limb length inequality study in children
Part of Bones, joints & muscles clinical trials.
This study looks at how a difference in leg length affects balance and movement in children aged 10 to 15. It uses a special low-dose X-ray (EOS) to take pictures of the child's spine and legs while they stand still.
Summary written for real people, not researchers, by Clin2.

This study gathers information on children with leg bone or muscle problems (from birth or later) to better understand their conditions. It may help improve future care for kids with similar issues.
This study looks back at records of children, age 12 or younger, who had surgery to lengthen a leg bone using the Precice nail or an external fixator. The goal is to understand how well these treatments work for kids with a leg length difference of at least 2 cm.
This study tests if ultrasound can accurately measure the length of magnetically controlled growing rods used in leg bone lengthening. It may help doctors monitor treatment without extra X-rays.
This study measures leg muscle strength in healthy children ages 5 to 16 to better understand normal development. If your child is developing typically and can follow instructions, they may be able to join.
This study looks at how children's legs heal after a thigh bone break that was treated with gentle skin traction. It helps doctors understand if any lasting shape changes happen, and why that matters for your child's future growth.
This study looks at how a child’s growth plate grows during and after a temporary growth plate procedure. It may help doctors better time and plan treatment for children whose leg alignment or leg length differs.
