Possibly, but more likely to present more obvious discomfort during hock extension and through the sacroiliac.
If the horse is very tender without his back shoes could the way he subtly compensates for that pain eventually lead to a sore stifle and flank area? Where the muscle is pretty hard to touch and painful at the slightest pressure?
Yep, particularly if the shoe provided extended heels and or lateral support. Lateral support eases load at the distal and central tarsal joints and can ease discomfort associated with bone spavin at the medial/anterior aspect of the hock. Extended heels set the foot down sooner, easing tension on the stifle and, to a much lessor extent, the SI.
If the horse needed that support and the support is removed, discomfort at the hocks can cause secondary muscle discomfort higher up in the limb and through the SI region.
Increasing phalangeal length (toe length) of the hinds can also increase discomfort as the unload phase of the stride is delayed, increasing pressure on the stifle.
Interested to hear more. Would love to know why/why not this is possible.
Hope you find that helpful.
