A modified chevron osteotomy with screw fixation offers a reliable solution for hallux valgus. This surgical technique improved patient symptoms and radiographic alignment with minimal complications.

Area of Science:

  • Orthopedic Surgery
  • Foot and Ankle Surgery
  • Surgical Innovation

Background:

  • Hallux valgus is a common foot deformity causing pain and functional limitations.
  • Traditional chevron osteotomy may have limitations in stability and healing.
  • Need for reliable surgical options for mild to moderate hallux valgus.

Purpose of the Study:

  • To evaluate the efficacy and safety of a modified chevron osteotomy for hallux valgus.
  • To assess radiographic and clinical outcomes of the modified procedure.

Main Methods:

  • A modified chevron osteotomy with added screw fixation and adjusted osteotomy angle was performed on 36 patients.
  • Patients had mild to moderate symptomatic hallux valgus.
  • Standing radiographs were analyzed preoperatively, at 1 month, and at long-term follow-up (≥1 year for 15 patients).

Main Results:

  • Overall, 35/42 procedures were rated satisfactory without reservations, and 7 with mild reservations.
  • All patients reported improvement in pain, cosmetic concerns, and shoe wear.
  • Significant improvements were observed in the average metatarsophalangeal-1 angle (8 degrees) and intermetatarsal 1-2 angle (4 degrees), with no radiographic complications.

Conclusions:

  • The modified chevron osteotomy is a simple, stable, and reliable procedure for mild to moderate hallux valgus.
  • The technique allows for early weightbearing and demonstrates excellent clinical and radiographic outcomes.
  • This modification enhances stability, reducing the risk of complications like nonunion or displacement.
