Abstract

PURPOSE: To evaluate the clinical symptoms, useful diagnostic tools and radiological findings and results of treatment on naviculocuneiform coalition.
MATERIALS AND METHODS
Nineteen cases, in 11 patients with naviculocuneiform coalition were reviewed by specific clinical manifestations. Radiological results, invasive degree and morphology of the coalition were measured on plain radiographs, CT, and bone scan. The suit-ability of bone scan and the characteristic morphology of coalition on the CT were reviewed.
RESULTS
The chief complaints were fatigue, pain and tenderness on the plantar surface of the midfoot. The average degree of invasion was 37% and no difference was evident between the symptomatic and asymptomatic group in this respect. According to the morphology of coali-tion, there were cause of irregular (5 cases), cystic (2 cases), and mixed type (12 cases). CT was the most effective test for diagnosis and char-acterizing the morphology. If pain remained after conservative treatment for 6 months, fusion of the naviculocuneiform joint was performed (2cases), which proved effective.
CONCLUSION
Disorders of the naviculocuneiform coalition are uncommon but the diagnosis may be established more frequently and earli-er with increasing awareness of the condition. CT was the most reliable test for evaluating naviculocuneiform coalitions and for demon-strating its characteristic morphology. Conservative treatment is effective in most patients.
