Navicular Bursoscopy (key-hole surgery for navicular disease)
Case Overview:
History:
This horse has a long-standing history of intermittent fore limb lameness. While initially responsive to corrective shoeing and conservative medical therapies, the lameness returned - raising concern for deeper soft tissue pathology.
Clinical Summary:
Diagnostic blocks localized the lameness to the foot and a foot MRI was performed standing - under light sadation only.
MRI Findings – Right Front Foot
Multiple significant abnormalities within the podotrochlear apparatus, including:
1) Moderate to marked deep digital flexor tendinopathy – core lesions in both medial and lateral lobes extending to the insertion, with dorsal surface disruption
2) Chronic navicular bursitis with probable adhesions
3) Flexor cortical defect of the navicular bone with surrounding bone remodeling
4) Moderate to marked synovitis of the distal interphalangeal joint
Next Step:
Navicular Bursoscopy
A navicular bursoscopy (key-hole surgery into the navicular bursa) was used to address adhesions and tendon damage. This minimally invasive approach allows direct visualization and debridement of affected structures, with the goal of restoring function in this apparatus and improving long-term soundness.
