Hallux Valgus: A modified Kramer osteotomy

Abstract 

Objective

The purpose of this study is to evaluate the outcomes for surgical treatment of Hallux Valgus deformity with the use of modified Kramer osteotomy.

Methods

From January 2003 to January 2005, 101 (23 bilaterally) modified Kramer osteotomies were performed in 78 patients evaluated clinically (74 of 78) with a phone interview and radiographic assessment with a mean follow up of 23.3±6.9 months.

Results

The average grade of satisfaction score was 7.9±2.0 (0–10). 82.4% of patients would come back to be operated by the same surgery if necessary, 6.7% needed special shoes, 21.6% needed insoles, 87.8% practiced sports activity. The postoperative radiographic assessments in metatarsophalangeal, intermetatarsal, distal metatarsal articular angle and sesamoid reduction showed a significant change (p<0.001), compared with the preoperative values. Complications: 1.2% vein thrombosis, 1.2% deep infection, 6.7% recurrences and 17.8% hipercorrected distal metatarsal articular angle.

Conclusion

The modified Kramer osteotomy enables a good correction in mild and moderate HV deformity with low rate of complications.
