On<br \/>\nstanding anteroposterior (AP) foot radiographs, we measured first metatarsal (M1), second metatarsal (M2), proximal<br \/>\nphalanx (P1), and the entire hallux (HX) lengths. M1\/M2 and P1\/HX ratios were calculated. The first metatarsophalangeal<br \/>\njoint space was calculated. All measurements were recorded preoperatively, at 6 weeks postoperatively, and at final<br \/>\nfollow-up.<\/p>\n<p><strong>Results:<\/strong>\u00a0The pilot study included 11 patients. At final follow-up, we found shortening of M1 and P1 in comparison to<br \/>\nthe preoperative length, as evidenced by lower M1\/M2 (82.6 \u00b1 2.3 vs 75.4 \u00b1 5.1; P = .001) and P1\/HX ratios (53.4 \u00b1 2.3 vs<br \/>\n48.9 \u00b1 7.9; P = .001).
