Category: Bunion Introduction/Purpose: Hallux valgus can be corrected by a variety of procedures. The Lapidus procedure corrects the first ray position in three planes using a first tarsometatarsal fusion (TMTF) and distal release and realignment. In a single surgeon practice the procedure was performed open until 2017, when burrs became available to perform the procedure percutaneously. This study compares the early radiographic results and complications of the percutaneous procedure with the open procedure. Methods: 47 patients undergoing the percutaneous procedure were compared with 44 patients undergoing the open procedure prior to July 2017. Radiographic measures preoperatively were compared to the postoperative measures for intermetataral angle (IMA), Hallux valgus angle (HVA), foot width (FW), distal metatarsal articular angle (DMMA), sesamoid station, metatarsus adductus angle (MAA), first metatarsal to second metatarsal length, and elevation of the first metatarsal. Early 30 day complications were recorded, as well as repeat surgeries. Demographics: There were 81 female and 10 male patients; The average age was MIS 58+/- 13, open 62+/-13. BMI was 28.4 vs 25.1. 1% of patients had diabetes, and 15% were smokers. Statistical analysis was performed using ANOVA. Because of multiple comparisons p
