MRI findings associated with navicular bursa medication in the horse : good therapeutic choice or a dangerous one? Preliminary results

Navicular bursa injection (NBI) with corticosteroids (CS) in horses with palmar foot pain is controversial: NBI often cause a rapid worsening of deep digital flexor tendon (DDFT).1,2 The magnetic resonance imaging (MRI) has the capability to detect hemosiderin depositation as result of NBI and to evaluate the direction of the needle and verify the correlation with changes in the DDFT.The aim of this study was to investigate the correlation between MRI findings of haemosiderin depositation due to NBI and DDFT lesions. Furthermore, the eventuality of intratendinous injection into the DDFT performing NBI was investigated.
