Comparative Study
Growth guidance system for early-onset scoliosis: comparison of experimental and retrieval wear.
Laboratory study conducted using an in vitro wear simulator with a growth guidance system. Analysis of variance performed to compare in vitro specimens (n = 6) with in vivo retrieval components (n = 5). ⋯ An in vitro wear analysis for a spinal growth guidance system was conducted using a novel protocol and validated against retrieved implants. This is the first study establishing a baseline value for the wear of "growth enabling" devices for the treatment of early-onset scoliosis.
