Spinal Lengthening With Magnetically Controlled Growing Rods: Data From the Largest Series of Explanted Devices.

Study Design: Laboratory analysis of explanted MAGnetic Expansion Control (MAGEC) rods.

Objective: The aim of this study was to identify the in vivo lengthening of MAGEC rods.

Summary Of Background Data: Little data is available regarding the lengthening achieved by MAGEC rods.

Force Testing of Explanted Magnetically Controlled Growing Rods.

Study Design: Laboratory analysis of explanted MAGnetic Expansion Control (MAGEC) growing rods.

Objective: The aim of this study was to measure the force produced by explanted MAGEC rods compared with new rods and assess the influence of clinical variables.

Summary Of Background Data: MAGEC rods are increasingly used in early-onset scoliosis.
