Dr. Harry Shufflebarger, Director of the Division of Spine Surgery at Nicklaus Children's Hospital is featured as part of this half hour segment in the Planet TV series for broadcast on national television.
Our 10 year old son, Ryan, tore his Anterior Cruciate Ligament (ACL) in his left leg this past summer. I have frequently been asked, isn’t 10 years old very young to tear an ACL? Yes, for children that young, it is rare, but not unheard of. And for adolescents and teenagers, ACL injuries are occurring more frequently, likely due to early sport specialization, and the increase in travel sports and year-round training.
