When Mayuri explained to Ichigo how a broken Bankai is different from a broken Shikai, and the effects of that, he said that the blades of Hihiô Zabimaru that broke during Renji's fight with Byakuya, are still broken. That was in Bankai, so I don't know how that could affect the Shikai.

The Bankai has many more blades/links than the Shikai, but I don't know if permanently breaking some blades in Bankai also damages the Shikai.
