Early coronal alignment after hallux valgus surgery predicts recurrence. Maintaining good alignment at 3 months post-op is crucial for preventing hallux valgus recurrence and improving patient outcomes.

Area of Science:

  • Orthopedic surgery
  • Radiology
  • Biomechanical analysis

Background:

  • Hallux valgus recurrence is a significant complication even after the modified Lapidus procedure.
  • Assessing early radiographic alignment is key to understanding long-term outcomes.

Purpose of the Study:

  • To determine the association between early postoperative radiographic alignment and the recurrence of hallux valgus.
  • Utilize routine weight-bearing radiographs for this investigation.

Main Methods:

  • Retrospective cohort study of 52 feet (43 patients) undergoing modified Lapidus for severe hallux valgus.
  • Weight-bearing radiographs analyzed preoperatively, at 3 months, and final follow-up (≥12 months).
  • Coronal and sagittal parameters assessed; recurrence defined by final hallux valgus angle (HVA) >20°.

Surgical Approach and Complications of Stand-alone Lateral Trans-Psoas Interbody Fusion

Published on: February 14, 2025

Main Results:

  • Recurrence occurred in 13.5% of feet.
  • Early recurrence group showed significantly worse coronal alignment (higher HVA, intermetatarsal angle) at 3 months.
  • Strong correlation between 3-month HVA and final HVA (ρ=0.944); poorer early alignment linked to worse patient-reported outcomes.

Conclusions:

  • Early postoperative coronal alignment on weight-bearing radiographs strongly predicts hallux valgus recurrence after the modified Lapidus procedure.
  • Adequate early coronal correction is vital for optimizing long-term surgical success and patient satisfaction.
