A method for guiding a saw blade (22) during preparation of a metatarsal (14) of a foot (10) for a procedure, such as to receive a metatarsal bone implant (20), includes positioning a housing (242) substantially adjacent to the metatarsal (14), coupling an aligner (38) to the housing (242), and aligning a saw guide (30) of the housing (242). The housing (242) includes the saw guide (30) for receiving and guiding the saw blade (22). The foot (10) includes one or more additional metatarsals (142), and the aligner (38) is used to align the saw guide (30) relative to the metatarsal (14) by aligning the aligner (38) to be substantially parallel to and positioned over a longitudinal axis (40) of one of the additional metatarsals (142).
