Migliore guided Ojibway to a head victory over Storm Boot Gold in the $49,000 allowance race.
The injury took place in the paddock prior to a race at Belmont Park on Oct. 20.
"Getting back took a lot of work," said Migliore. "To come back and have that hard work rewarded right away was emotional for me."
Migliore, who turns 42 on March 14, has won more than 4,000 races.
Ojibway ran the six furlongs on the fast track in 1:10.55 and paid $8.40, $6.40 and $2.20. Storm Boot Gold paid $7 and $2.20. Silver Flower got the show spot and paid $2.10.
