Summary

Surgical correction of moderate to severe hallux valgus using proximal crescentic osteotomy and distal soft-tissue repair significantly reduced pain and improved function. This procedure effectively corrected deformities and normalized first ray mobility, offering excellent outcomes for patients.

Area of Science:

  • Orthopedic Surgery
  • Foot and Ankle Surgery
  • Surgical Outcomes Research

Background:

  • Limited prospective studies exist on surgical outcomes for hallux valgus.
  • This study addresses the need for evidence on operative treatment of hallux valgus deformities.

Purpose of the Study:

  • To evaluate the efficacy of surgical treatment for hallux valgus using a proximal crescentic osteotomy and distal soft-tissue repair.
  • To assess the impact of this surgical technique on the first metatarsophalangeal joint.

Main Methods:

  • Prospective study of adult patients with moderate to severe subluxated hallux valgus.
  • Surgical repair involved proximal crescentic osteotomy and distal soft-tissue reconstruction.
  • Outcomes assessed via preoperative/postoperative pain and AOFAS scores, range of motion, first ray mobility, and radiographic measurements at minimum two-year follow-up.

An Anatomical Study of Nerves at Risk During Minimally Invasive Hallux Valgus Surgery

Published on: February 17, 2018

Main Results:

  • Significant improvement in mean pain scores (6.5 to 1.1) and AOFAS scores (57 to 91).
  • 93% of feet achieved good or excellent results; hallux valgus angle reduced from 30 to 10 degrees.
  • First ray mobility normalized in most cases; recurrence observed in 6% of feet.

Conclusions:

  • Proximal crescentic osteotomy with distal soft-tissue repair is a viable surgical option for moderate to severe hallux valgus.
  • The procedure effectively reduces first ray mobility without necessitating metatarsocuneiform arthrodesis.
  • Plantar gapping is not a reliable indicator of sagittal plane first ray hypermobility.
