Purpose:The purpose of this study was retrospectively to evaluate the results of the modified Kidner procedure for symptomatic accessory navicular in athletes.
Materials and Methods: Between July 1999 and December 2004, 26 feet in 22 patients with symptomatic accessory navicular who had underwent modified Kidner procedure were available for clinical follow-up, and 12 cases in 9 patients were available for clinical and radiological follow-up with a
minimum follow-up of 5 years were included in this study. All those patients had symptomatic accessory navicular bone who underwent modified Kidner procedure. American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score, Visual Analogue Scale (VAS), and satisfaction rate were
investigated. Talo-first metatarsal (T-MT1) angle, talo-calcaneal (TC) angle, and calcaneal pitch (CP) angle were measured in standing lateral radiograms.
Results: AOFAS score was improved from 40.8±7.5 (32~57) preoperatively to 88.7± 8.0 (72~100) postoperatively, and the difference was significant (p<0.01). VAS was improved from 7.0±0.9 (5~9) preoperatively to 1.8±0.8 (1~4) postoperatively, and the difference was significant (p<0.01). At the
lastest follow up, 11 feet were very satisfied, 11 feet satisfied, and 4 feet unsatisfied (a satisfaction rate 85.0%). No significant difference was observed for T-MT1 angle (p=0.67), TC angle (p=0.93), and CP angle (p=0.49).
Conclusion: Modified Kidner procedure for the symptomatic accessory navicular showed satisfactory results and is appeared to be one of the useful treatments.
