Abstract

BACKGROUND:

We aimed to compare the clinical and radiographic outcomes of minimally invasive surgery (MIS) and distal chevron metatarsal osteotomy (DCMO) for young female patients with mild-to-moderate juvenile hallux valgus deformity.

METHODS:

We retrospectively reviewed the radiographs and clinical findings of young female patients with mild-to-moderate juvenile hallux valgus who underwent MIS (25 feet) or DCMO (30 feet). In 12 of 25 MIS feet, 2.0-mm bio-absorbable pins were used as an additional fixation device crossing the osteotomy site, and 1.4-mm Kirschner wires were used in the remaining 13 feet.

RESULTS:

Radiographic and clinical parameters preoperatively and at the final follow-up were not significantly different between the 2 groups. There were no significant differences in the increments of hallux valgus angle (HVA), distal metatarsal articular angle, medial sesamoid position, first metatarsal length, metatarsal length index, or relative second metatarsal length. Two MIS subgroups according to the additional fixation device showed no significant differences in HVA, the first to second intermetatarsal angle lateral translation ratio, or plantar offset at the final follow-up.

CONCLUSIONS:

MIS for young female patients with mild-to-moderate juvenile hallux valgus deformity had similar radiographic and clinical outcomes compared to DCMO. Regarding additional fixation crossing the osteotomy site, both temporary Kirschner wires and absorbable pins showed no radiographic differences in terms of correction maintenance.
