Jockey Marlon St. Julien, who injured his spine in a one-horse spill at the start of a race last Saturday night at Prairie Meadows, still was in an intensive-care unit as of Wednesday. St. Julien underwent surgery on Sunday to relieve pressure on his spinal cord. St. Julien still is intubated but is awake, able to communicate, and has movement in his limbs, according to Robin Dean, the wife of St. Julien’s agent, Bobby Dean. She has visited St. Julien several times in the hospital and has monitored his condition. A full evaluation, treatment plan, and prognosis can’t be fully formed until inflammation at the injury site subsides and St. Julien’s overall condition improves.
