Summary
Basal chevron metatarsal osteotomy effectively corrects painful hallux valgus. This surgical procedure significantly improves foot alignment and reduces pressure points, leading to high patient satisfaction.
Area of Science:
- Orthopedic Surgery
- Podiatry
- Biomechanics
Background:
- Hallux valgus is a common foot deformity causing pain and affecting appearance.
- Increased intermetatarsal 1/2 angle is a key indicator of severe hallux valgus.
- Surgical intervention aims to correct alignment and alleviate symptoms.
Purpose of the Study:
- To evaluate the efficacy of basal chevron metatarsal osteotomy for hallux valgus.
- To assess radiological and pedobarographic changes post-surgery.
- To determine patient satisfaction following the procedure.
Main Methods:
- 32 feet (31 patients) with hallux valgus and increased intermetatarsal 1/2 angle underwent basal chevron metatarsal osteotomy.
- Preoperative and postoperative radiological and pedobarographic examinations were performed.
- Minimum six-month follow-up was conducted.
Main Results:
- Average hallux valgus angle improved from 40.9 to 19.2 degrees.
- Intermetatarsal 1/2 angle improved from 16.5 to 6.8 degrees.
- Significant reduction in high-pressure areas (> 5 kg/cm2) and increased foot contact area observed on pedobarography.
Conclusions:
- Basal chevron metatarsal osteotomy is an effective treatment for hallux valgus.
- The procedure leads to significant radiological correction and improved foot biomechanics.
- High patient satisfaction indicates successful symptom relief and aesthetic improvement.
