Background Hallux valgus correction is mostly done by metatarsal procedures, and widely accepted strategy is to decide which surgical method should be used is based on radiological severity using intermetatarsal (IMA) and hallux valgus (HVA) angles (classical angular correction approach—CACA). The aim of the study is to compare the postoperative improvement in radiographic parameters and morphologic appearance of the foot between patients operated with and without adhering to CACA strategy based on classical severity classification using angle measurements. Materials and methods A retrospective comparative study between two groups (conforming and not conforming to proposed algorithm) was performed. Of 122 feet of 119 patients underwent metatarsal procedures for hallux valgus between October 2022 and November 2023, 92 feet of 92 patients were enrolled in the study (age 43.86 ± 16.1 years, 15.2% male). Patients were classified into two groups as conforming and non-conforming to CACA algorithm based on IMA and HVA angles (mild: IMA ≤ 13°, HVA ≤ 30°; moderate: 13°
