 MR Findings:
There is marked damage to the lateral collateral ligament of the coffin joint of the right front foot. This includes focal areas of increased signal at both the origin as well as the insertion of the ligament. In addition, there is lysis of the bone at the insertion site on P3. The collateral ligament is diffusely enlarged with increased signal noted on all sequences. There is evidence of chronic proliferative bone on the dorsal surface of P3 on the lateral quarter. There is a slight irregularity noted in the sensitive lamina in this location. |
Impressions and Recommendations:
Severe lateral collateral ligament desmitis of the right front foot with associated changes at both the origin and insertion sites on both P2 and P3. The pedal osteitis and lamellar degeneration noted are likely contributing to the lameness. This case is quite severe given the degree of bone and soft tissue pathology. Many cases may have an enlarged collateral ligament with little or no signal or little or no boney changes. Although often reported, this is likely a more common variation of normal in an athlete. Prognosis for long term service ability is guarded. Potential treatments could include shock wave therapy, IRAP, shoeing changes and extended rest. |
