A new surgical technique, the crescentic "shelf" osteotomy, offers precise correction for hallux abducto valgus. This method enables stable fixation and accurate reduction of the first metatarsal base for improved outcomes.

Area of Science:

  • Orthopedic Surgery
  • Foot and Ankle Surgery
  • Skeletal Biomechanics

Background:

  • Hallux abducto valgus (HAV) is a common foot deformity requiring effective surgical correction.
  • Existing osteotomy techniques for HAV may have limitations in achieving triplanar correction and precise reduction.
  • The first metatarsal base presents complex anatomical challenges for surgical correction of HAV.

Purpose of the Study:

  • To introduce and describe a novel surgical technique, the crescentic "shelf" osteotomy, for correcting hallux abducto valgus.
  • To evaluate the efficacy of this new technique in achieving triplanar correction and stable fixation.
  • To provide a comprehensive guide for the procedure, including anatomical considerations and potential complications.

Main Methods:

  • Description of the crescentic "shelf" osteotomy, combining dorsal-to-plantar crescentic and medial-to-lateral transverse osteotomies at the first metatarsal base.
  • Discussion of anatomical considerations of the first metatarsal and prediction of distal fragment motion.
  • Presentation of a procedural guide, case examples, and analysis of 22 procedures.

    • Main Results:

    • The crescentic "shelf" osteotomy allows for triplanar correction of hallux abducto valgus.
    • The technique provides stable open reduction with internal fixation.
    • Precise intermetatarsal angle reduction was achieved, with analysis of 22 procedures presented.

    Conclusions:

    • The crescentic "shelf" osteotomy is a viable new surgical technique for hallux abducto valgus correction.
    • This method offers advantages in achieving stable, precise, and multi-planar correction.
    • Further evaluation and comparison with existing techniques may be warranted.
