Figure 2From: Axial osteitis of the proximal sesamoid bones and desmitis of the intersesamoidean ligament in the hindlimb of Friesian horses: review of 12 cases (2002-2012) and post-mortem analysis of the bone-ligament interfaceMacroscopic view of the PSBs and the ISL of a diseased and a non-diseased Friesian horse. Note the focal loss of bone at the proximo-axial aspects of the PSBs (open arrows). Concurrent partial rupture of the ISL (white line marked area), starting at the proximal level of the bone and coursing to distal with locally a detachment from the bone (black arrows). The rupture did not enter the plantar surface so there was no penetration into the DFTS in this case.Back to article page
