Background: This study aimed to investigate the radiographic measurements associated with the progression of hallux valgus during at least 2 years of follow-up. Methods: Seventy adult patients with hallux valgus who were followed for at least 2 years and underwent weightbearing foot radiography were included. Radiographic measurements included the hallux valgus angle (HVA), hallux interphalangeal angle, intermetatarsal angle (IMA), metatarsus adductus angle, distal metatarsal articular angle (DMAA), tibial sesamoid position, anteroposterior (AP) talo-first metatarsal angle, and lateral talo-first metatarsal angle. Patients were divided into progressive and nonprogressive groups. Binary logistic regression analysis was performed to identify factors that significantly affected the progression of hallux valgus deformity. The correlation between change in HVA and changes in other radiographic indices during follow-up was analyzed. Results: The DMAA (P = .027) and AP talo-first metatarsal angle (P = .034) at initial presentation were found to be significant factors affecting the progression of hallux valgus deformity. Change in the HVA during follow-up was significantly correlated with changes in the IMA (r = 0.423; P = .001) and DMAA (r = 0.541; P < .001). Conclusion: The change in the HVA was found to be significantly correlated with changes in the IMA and DMAA. A future study is required to elucidate whether this correlation can be explained by the progressive instability of the first tarsometatarsal joint. We believe special attention needs to be paid to patients with pes planus and increased DMAA. Level of Evidence: Level III, comparative study.
