However, how to correct three\u2010dimensional deformities in hallux valgus effectively and simply in MICA is still difficult. Special equipment is required in MICA as has been reported before. It is meaningful and necessary to reduce the reliance on special equipment in MICA.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>From January 2021 to July 2022, patients with mild or moderate hallux valgus were treated with a joy\u2010stick assistant three\u2010dimensional modified technique (Joy\u2010stick 3D technique) of MIS. VAS, AOFAS Hallux MTP\u2010IP scores, hallux valgus angle (HVA), intermetatarsal angle (IMA), and distal metatarsal articular angle (DMAA) were measured pre\u2010 and postoperatively at the last follow\u2010up of at least 6\u2009months. Scores and radiologic angles were compared using paired sample t\u2010test.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 36 cases were included.

VAS decreased from 4.3\u2009\u00b1\u20091.7 to 0.7\u2009\u00b1\u20090.7. AOFAS Hallux MTP\u2010IP scores improved from 68.6\u2009\u00b1\u20097.6 to 92.9\u2009\u00b1\u20096.1.
