Area of Science:

  • Orthopedic Surgery
  • Podiatric Medicine
  • Skeletal Biomechanics

Background:

  • Hallux valgus, a common foot deformity, often requires surgical intervention.
  • Traditional osteotomies may lead to complications like metatarsus elevatus and metatarsalgia.
  • The modified Wilson osteotomy aims to address these limitations through specific fragment displacement.

Purpose of the Study:

  • To evaluate the long-term efficacy and outcomes of the modified Wilson osteotomy for hallux valgus.
  • To assess the procedure's impact on radiographic parameters and patient satisfaction.
  • To determine the incidence of complications such as metatarsalgia post-surgery.

Main Methods:

  • A retrospective review of 74 hallux valgus cases treated with modified Wilson osteotomy.

Related Experiment Videos

  • Postoperative assessment at five years, including clinical grading and radiographic analysis.
  • Measurement of hallux valgus angle, intermetatarsal angle, and first metatarsal length.

    • Main Results:

    • 89% of patients reported satisfactory outcomes after five years.
    • Significant reduction in hallux valgus angle (average 15 degrees) and intermetatarsal angle (average 4 degrees).
    • Average 5 mm shortening of the first metatarsal, leading to forefoot callosities but not metatarsalgia.

    Conclusions:

    • The modified Wilson osteotomy is a technically straightforward procedure for hallux valgus.
    • It achieves high patient satisfaction rates and effectively corrects key radiographic deformities.
    • The technique demonstrates a low risk of inducing metatarsalgia despite first metatarsal shortening.
