1. A method of correcting a hallux valgus deformity, the method comprising:
bisecting a metatarsal into a first fragment and a second fragment;
inserting an intramedullary (IM) member that is attached to a first screw mechanism into an intramedullary canal of one of the first fragment or the second fragment of the metatarsal;
aligning the first screw mechanism such that a longitudinal axis of a first screw of the first screw mechanism is substantially perpendicular to a longitudinal axis of the first fragment of the metatarsal; and
rotating the first screw to generate a lateral force between a position of the IM member and a first skin-interfacing portion at an end of the first screw located against the first fragment of the metatarsal or medial skin of the first fragment of the metatarsal.
