Abstract

Minimally invasive surgery for hallux valgus is evolving, but the optimal fixation method and its applicability to severe deformity remain debated. We describe a percutaneous distal metatarsal osteotomy (PDMO) using a Shannon burr, lateral soft-tissue release, and a 2.0-mm Kirschner wire crossing the first tarsometatarsal joint into the medial cuneiform, allowing immediate flat-sole weight-bearing.
Thirty-four patients (36 feet) were retrospectively reviewed. Hallux valgus angle (HVA), intermetatarsal angle (IMA), Self-Administered Foot Evaluation Questionnaire (SAFE-Q), and complications were analyzed; severe deformity (HVA ≥40°; n = 20) was examined separately.
HVA improved from 37.8 to 5.7° and IMA from 16.1 to 5.3° (both p < 0.001). All SAFE-Q subscales improved. In severe deformity, HVA improved to 6.3° with comparable gains. No recurrence occurred; complications were 4 of 36 (11.1%), all minor.
This PDMO technique produced satisfactory correction and significant SAFE-Q improvement while permitting immediate flat-sole weight-bearing, including in severe deformity.
Level IV, case series.
