Abstract

Purpose

The purpose of this study was to evaluate the clinical outcome of a modified Kidner procedure using a suture bridge technique in symptomatic type II accessory navicular.

Materials and Methods

Between January 2013 and December 2014, a total of 35 cases with symptomatic type II accessory navicular were treated with a modified Kidner procedure using the suture bridge technique. The patients were evaluated preoperatively, 3 months after surgery, and at the latest follow-up (at least six months postoperatively) clinically via the American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score, visual analogue scale (VAS), and the self-subjective satisfaction score.

Results

The mean AOFAS midfoot score demonstrated significant improvement from a mean of 45.3 preoperatively to a mean of 89.2 at 3 months after surgery. At the latest follow-up, the mean AOFAS midfoot score was 92.6 (p<0.001). The mean VAS also improved significantly, decreasing from 6.7 out of 10 preoperatively to 1.8 at 3 months after surgery. At the latest follow-up, the VAS was 1.2 (p<0.001). The mean time of a single-limb heel raise was 4.6 months postoperatively and the self-subjective satisfaction score was 1.4 out of 4 at the latest follow-up.

Conclusion

The short-term surgical results of the modified Kidner procedure with a suture bridge technique for symptomatic type II accessory navicular were good to excellent in terms of pain, functional and clinical assessments. In conclusion, the modified Kidner procedure with the suture bridge technique is a reasonable treatment option for symptomatic type II accessory navicular.
