[The application radionuclide bone imaging in the treatment of hallux valgus]

Radionuclide bone imaging (RNBI) was performed by means of 99mTc-MDP on both 20 health subjects (40 feet) and 20 patients with hallux valgus (26 feet). The results showed that radioactivity intake were increased in second (or third) metatarsal of 26 feet of hallux valgus. The ratio of radioactivity of the lesion and contralateral normal site (D/N) had statistical difference (P < 0.01). Both the patient and normal groups RNBI is a highly sensitive study and valuable for the classification of diagnosis. It help for selection of surgical treatment, as to evaluate the results of the treatment.
