Area of Science:

  • Orthopedic Surgery
  • Foot and Ankle Surgery
  • Podiatric Medicine

Background:

  • Hallux valgus deformities are common, with numerous surgical treatments reported.
  • Prospective outcome studies evaluating surgical interventions are less frequent.
  • This study focuses on the Lapidus procedure for moderate to severe hallux valgus.

Purpose of the Study:

  • To prospectively evaluate the functional outcomes of the Lapidus procedure.
  • To assess outcomes in patients with moderate to severe hallux valgus (IMA > 14°, HAV > 30°).
  • To analyze long-term functional improvement and deformity correction.

Main Methods:

  • Prospective study of 91 patients (105 feet) undergoing the Lapidus procedure.
  • Inclusion criteria: failed nonoperative management for metatarsus primus varus and hallux valgus.

  • Data collected via AOFAS scale, VAS pain scale, clinical exams, radiographs, and patient questionnaires over an average of 3.7 years.

    • Main Results:

    • AOFAS scores improved significantly from 52 to 87 (p <.001).
    • Average intermetatarsal angle improved from 18° to 8.2°, and hallux valgus angle from 37° to 16°.
    • Complications included nonunion (7), loss of correction (5), and hardware removal (8).

    Conclusions:

    • The Lapidus procedure is an effective treatment for moderate to severe hallux valgus with metatarsus primus varus.
    • Proper technique and attention to detail are crucial for successful outcomes.
    • While not a universal solution, it provides an excellent alternative for specific deformities.
