Tethered Cord

Abstract

A 3-year-old boy who started walking at 18 months was in your clinic for his 3-year routine visit. His parent suggested that he seemed fine except when he became tired. As he tired, his left leg started to drag slightly. His mother did not notice that he complained of any pain after exercising but the fatigue was reproducible. She felt that the cosmetic appearance of his back looked normal but upon closer inspection, a subtle gluteal asymmetry was detected. Neurologically the child was completely normal except for decreased proprioception and light touch on the left.
