A bunion treatment method comprising:

• cutting a metatarsal bone of a foot into a first metatarsal portion and a second metatarsal portion;
• inserting a stem portion of an intramedullary implant into the first metatarsal portion and positioning at least one fixation aperture extending through a plate portion of the intramedullary implant overlying the second metatarsal portion, wherein the stem portion has a length extending from a first end to a second end with the plate portion being positioned at the second end of the stem portion, the stem portion extends at an angle relative to the plate portion, and inserting the stem portion of the intramedullary implant into the first metatarsal portion comprises positioning the first end of the stem portion in contact with a lateral cortical wall of the first metatarsal portion;
• and
• inserting a fixation member through the at least one fixation aperture extending through the plate portion of the intramedullary implant and into the second metatarsal portion to fixate a moved position of the second metatarsal portion relative to the first metatarsal portion.
