Deep digital flexor tendonopathy in the foot

Tendonopathy of the distal portion of the deep digital flexor tendon is a newly recognised, important cause of foot lameness in horses. Although the pathological morphology of lesions has been well described, the aetiopathogenesis remains uncertain. A conclusive diagnosis can only be made with magnetic resonance imaging, but the results of a thorough clinical examination, including regional analgesia and other imaging modalities may lead to a strong suspicion of deep digital flexor tendonopathy in the foot. The prognosis for return to soundness is guarded but new treatment modalities are currently being investigated for an improved outcome.
