Summary
This study reviewed a modified distal osteotomy for hallux valgus, finding it unreliable despite good subjective results in 90% of patients. Patient selection is crucial, especially for severe hallux valgus angles.
Area of Science:
- Orthopedic surgery
- Podiatric surgery
Background:
- Hallux valgus, a common foot deformity, often requires surgical correction.
- Distal osteotomy techniques are frequently employed to address hallux valgus.
- Assessing the long-term efficacy and reliability of surgical modifications is essential.
Purpose of the Study:
- To evaluate the outcomes of a modified distal osteotomy for hallux valgus correction.
- To determine the reliability and patient selection criteria for this specific surgical technique.
Main Methods:
- Retrospective review of 63 feet in 44 patients who underwent a modified distal osteotomy for hallux valgus.
- Surgical technique involved a modification of Mitchell's and Mommsen's osteotomies without internal fixation.
- Mean follow-up period was 4.6 years.
Main Results:
- Mean correction of intermetatarsal angle was 2.6 degrees; hallux valgus angle was 5.2 degrees.
- 90% of patients reported good subjective outcomes.
- 9.5% of cases showed worsening of the hallux valgus angle post-operatively.
- Hallux valgus angles greater than 40 degrees were less suitable for this procedure.
Conclusions:
- The modified distal osteotomy technique, as performed without fixation, demonstrated unreliability for hallux valgus correction.
- Careful patient selection is paramount for optimizing outcomes with this surgical method.
- The procedure may not be suitable for patients with severe hallux valgus deformities ( > 40 degrees).
