Abstract:
Hallux valgus (HV) accompanied by metatarsus adductus (MA) is a surgical challenge because of its anatomical characteristics, often presenting with a high hallux valgus angle (HVA) despite a low intermetatarsal angle (IMA). This case report describes a 66-year-old female who presented with a 15-year history of left foot pain and deformity. The radiographs revealed an HVA of 45.0° and a low IMA of 7.2°, consistent with concomitant MA. Instead of a traditional proximal osteotomy for severe HV, the patient underwent a minimally invasive transverse distal metatarsal osteotomy along with distal metatarsal minimally invasive osteotomies (DMMOs) of the lesser metatarsals. At the 2-year follow-up, the radiographs showed excellent correction (HVA 12.5°, IMA 1.0°). The patient was asymptomatic and reported high functional and cosmetic satisfaction. This case shows that a minimally invasive transverse distal metatarsal osteotomy, combined with adequate ancillary procedures, can achieve a successful correction even in complex, severe HV with MA.
