The modified Lapidus procedure effectively treats symptomatic hallux valgus with a hypermobile first ray, achieving high fusion rates and significant correction of foot deformities. This surgical approach shows promising outcomes, particularly with specific techniques like bone grafting and screw fixation.

Area of Science:

  • Orthopedic Surgery
  • Foot and Ankle Surgery
  • Podiatric Surgery

Background:

  • Hallux valgus, often accompanied by a hypermobile first ray, is a common foot deformity.
  • The Lapidus procedure is a surgical option for correcting these complex deformities.
  • Modifications to the standard Lapidus procedure aim to improve outcomes.

Purpose of the Study:

  • To evaluate the outcomes of a modified Lapidus procedure for hallux valgus with hypermobile first ray.
  • To assess the efficacy and complication rates of this surgical technique.
  • To identify factors associated with successful surgical outcomes.

Main Methods:

  • Retrospective review of 32 patients (40 feet) who underwent the modified Lapidus procedure between 1979 and 1984.
  • Analysis of preoperative and postoperative radiographic measurements, including intermetatarsal and hallux valgus angles.

  • Assessment of arthrodesis site union and clinical outcomes based on a defined rating system.

    • Main Results:

    • Arthrodesis site union occurred in 90% of cases.
    • Significant correction of intermetatarsal angle (14° to 6°) and hallux valgus angle (26° to 11°).
    • Successful outcomes reported in 75% of primary procedures and 100% of revision cases; bone grafting and screw fixation correlated with better results.

    Conclusions:

    • The modified Lapidus procedure is an effective treatment for symptomatic hallux valgus with hypermobile first ray.
    • Factors such as bone grafting, multiple screw fixation, and first metatarsal plantarflexion contribute to optimal results.
    • This procedure demonstrates good union rates and significant correction of deformities, with positive outcomes in both primary and revision surgeries.
