A short leg, or leg length discrepancy (LLD), is a fairly common condition in children. An LLD simply means that one of the child’s legs is of a different length. The difference varies widely, but the larger the difference, the more problems arise as the child grows.
An LLD is caused by anatomical or functional anomalies such as a pelvic tilt, healed fractures, or injury of the growth plates in the affected limb. If left untreated, an LLD can lead to more serious conditions such as scoliosis and arthritis, as well as chronic knee, back, and hip pain.
Signs and Symptoms
- One leg shorter than the other (this may not be visible)
- Toe walking
