What is it?

A long-length X-ray (teleradiography) is a large-format X-ray that shows, in a single image, the whole spine (from the skull to the pelvis) or one or both lower limbs (from the hip to the ankle). It is taken standing, weight-bearing, to show the spine and legs as they are when they carry your body weight. It allows precise measurement of a spinal curve, a difference in leg length or the alignment of the knees. For the spine, it can be taken from the front only or from the front and the side; for the legs, on one limb or on both.

When is it indicated?

Scoliosis

It measures the angle of the spinal curve and helps monitor its progression, especially during growth.

Leg length difference

It measures the difference in length precisely, for example to fit a shoe insert.

Knee alignment before surgery

Before a knee replacement or alignment correction, it shows whether the legs are bowed or knock-kneed.

Assessment of posture or imbalance

It assesses the overall balance of the spine and pelvis.
