Abstract

PURPOSE: To present our experience of distal chevron osteotomy utilizing one BOLD screw(R) as an alternative fixation method which has advantages over the Kirschner (K)-wire fixation.
MATERIALS AND METHODS
Between January 2001 and June 2003, 19 patients with a symptomatic hallux valgus deformity underwent 20 distal metatarsal chevron osteotomies with one BOLD screw(R) fixation. The mean age was 55.6 years with a minimum follow up period 12 months. For radiographical evaluation, hallux valgus angle (HVA) and intermetatarsal angle (IMA) were used. For clinical evaluation, we used AOFAS hallux metatarsophalangeal interphalangeal scale and overall satisfaction of the patients.
RESULTS
The AOFAS scores improved from mean 47.5 points to mean 68.1 points at postoperative 3 months and mean 86.0 points at last follow-up. The average HVA corrected from 25.3 degrees to 12.7 degrees. The IMA was corrected from 11.6 degrees to 7.6 degrees. The overall satisfaction of the patients was 85%. There was no major complication.
CONCLUSION
We demonstrated that distal chevron osteotomy with one BOLD screw(R) fixation has advantages such as no additional procedure, no loss of correction, early rehabilitation, no prominent hardware and skin irritation. This method also showed excellent bone union, correction and patient satisfaction.
