Claims20
A brachytherapy spinal implant, comprising:
- a spinal implant including a body extending along a longitudinal axis, a superior endplate disposed at one longitudinal end of the body, and an inferior endplate disposed at an opposing longitudinal end of the body, each end plate defining a vertebral-engaging surface configured to engage a complementary vertebral endplate;
- and
- a plurality of irradiated seeds attached to the implant body so as to direct radiation toward the spine in a desired direction when the brachytherapy implant is disposed in an intervertebral space.
A brachytherapy implant, comprising:
- a shaft defining a proximal end and a distal end, and a head attached to the proximal end of the shaft, wherein the shaft defines a cannulation configured to receive one or more brachytherapy seeds.
A method of treating a spinal tumor comprising the step of implanting a plurality of irradiated brachytherapy seeds into the spine at a location suitable to direct radiation toward the malignant cells.
