Some embodiments of the present disclosure relate to an implantable device for the closure and/or repair of a spinal defect (e.g., posterior annular defects) and/or preventing recurring herniation. An implantable medical device, in some embodiments, may be coated or impregnated with a releasable pharmaceutical compound. Accordingly, some embodiments of the present disclosure relate to compositions that include one or more pharmaceutical compounds. In addition, some embodiments of the disclosure relate to methods for making and using compositions and medical implants. A spinal implant may include, for example, a scaffold having a substantially planar surface; and a plurality of tails, each of which has a first end that is attached to the scaffold and a second end that is configured and arranged to be threaded through a respective perforation in a vertical body, wherein the scaffold comprises a pharmaceutically effective amount of a pharmaceutical agent.
