An implant port for repeated access to the medullary portion of bone is provided. The implant port includes an access port fittable into a surgically constructed bone orifice and an insert means that seals and fills the port volume. A penetrable insert means allows repeated access within bone using sharp surgical instruments; while an adapter means allows guided placement of a surgical instrument, such as a catheter, optical device, or rotating cutter. Skeletal surgery from the inside of bone is contemplated using the implant port provided.
