An ex-employee at a Manhattan orthopedic surgeon’s office was sent off on a six-month jail sentence yesterday for her role in a scheme in which oxycodone pills were sold out of a Staten Island ice-cream truck.

Nancy Wilkins, of Brooklyn, had pleaded guilty to conspiracy for selling blank pages out of her boss’ prescription pad for $100 apiece. She’ll serve five years of probation upon her release.

Her co-defendants — Louis Scala Jr. and Joseph Zaffuto — have pleaded not guilty to the scheme, in which Scala allegedly sold Good Humor ice cream and $20-a-pop pills out of his truck.
