Tendon Adhesion

SIGNALMENT

21 year old Quarter Horse Mare

HISTORY

Left forelimb lameness, with improvement due to palmar digital nerve analgesia. Previous studies showed mild degenerative changes to the navicular bones. Treament consisted of intra-articular injection of both distal interphalangeal joints with corticosteroids and hyaluronan, and corrective shoeing. Lameness persisted.
She was also treated for Lyme disease with doxycycline and for hypothyroidism with Thyro-L.

PRESENTATION

1o out of 5o lameness on the left front
The remainder of physical exam findings were unremarkable.

DIAGNOSIS AND PROGNOSIS

The MRI revealed the presence of an aberrant tendinous tissue arising between the deep digital flexor tendon and the navicular bursa. Because this tissue was of similar appearance and intensity as the main portion of the deep digital flexor tendon, it remains difficult to determine if it is a true lesion (adhesion) or a variation of normal.

TREATMENT

Treatment options for this case include corrective trimming and shoeing, judicious administration of intra-articular medications into the distal interphalangeal joint, and possibly palmar digital neurectomy should her lameness persist or worsen in the face of conservative management.
