Hi folks have the vet coming today to vaccinate Pete so no riding for me, a friend's horse has just been diagnosed with thoroughpins in both hind legs, he was for sale and has failed a vetting. What are they and how do you get them? Would also love to know more about ringbone, sidebones,windgalls all the leg things really?

oh here missus you dont want much!!  thoroughpin is actually a type of windgall- a tendinous windgall to be precise- which is the swelling of the tendon where it passes over the hock. its a sort of soft squishy swelling and it generally caused by concussion , an injury or a blow ( less likely if he has 2) horses with poor conformation are more likely to have it. it tends not to cause lameness - although it is a vet failure so there is no particular treatment. avoid working on hard/uneven ground to prevent. the other type of windgall is an articular which a swelling of the joint capsule in the fetlock joint - causes etc same as thoroughpin. Ringbone can be true/false and high/low and is degenerative bone disease- usually the front legs true ringbone is in a joint whereby the inflamation of the joint capsule breaks down the articular cartilage - the body can then create new bone in place with stops movement in the joint. False is when there is damage to the bone and new bone is created but its not actually in the joint. High is pasern joint or bones and low is coffin joint short pastern or pedal bone. causes again poor conformation direct blow or injury damage to the joint or stress on the joint (polo ponies are very susceptible) its incurable. sidebone is where the lateral cartilage around the pedal bone becomes bone (ossified) causes lameness and same causes as the others in can be helped with corrective shoeing phew  |

Maxi - Fab descriptions.  One really, really minor point about side bone. It's the ungular cartilages (also known as lateral cartilages) at the palmar (back) part of the foot which ossify. It's usually as a result of imbalance in the foot or poor confirmation (eg long fetlocks). Osteoblasts ossify the cartilage in an attempt to stabilise the area. With corrective shoeing or good barefoot care (if problem is down to feet) Osteoclasts can change the ossified cartilage back again. |

Thank you folks you're good! My friend's pony has side bones another friend that is and she is really well except a bit arthritic in the mornings. Thanks again.

I find this fasinating - how do they de-ossify? isnt the world of nature wonderful!- you can PM me if its all scientific as you may have to take it slow! as joandlad says almost all these are due to poor conformation - another reason NOT to breed froma mare who goes lame!! |

there are 2 type of spavins - bone and bog.
bone is the degeneration of the hock more specifically the joint between the tarsal bones.
The symptoms are a stiffness in the back leg- shorter stride and perhaps the toe being dragged with an irregular rythtym to the sound of the footfalls. there are swellings on the inner lower area of the hock with heat and pain. this will lead to lameness.
Its caused by jusr wear and tear to the hocks - seen a lot on horses who do a lot of twisting and turning actions on the hocks so jumpers polo ponies, like all these it is seen more often in horses with poor conformation (sickle or cow hocks). The tarsal (hock) bones will eventually fuse at the the joint.
Its an incurable condition . It can be managed until such tie as the joint becoes fused and the horse is then no longer in pain and can carry out some light work. again corrective foot work can help.
Bog Spavin is a swelling in the joint capsule round the hock.
symptoms are swelling around the hock area generally a larger one to the front inside and a smaller one on the outside of the hock under the point of hock - if you press one the other bulges.
normally caused by injury or blow- the joint produces large amounts of synovial fluid to prtect the joint which is what caused the swelling - ditto the poor conformation which makes them more prone to injury .
theres not much you can do and it should not affect the horse in any way. If its lame is more probably bone than bog spavin

Only just found this thread so sorry if I'm a bit late...
Maxi - I love reading your threads/responses because I always learn so much! Yours too Jo!!
I've heard of osteoclasts and osteoblasts and stuff but never in much detail...I'd love to know how they work too if someone doesn't mind explaining it to me??
As for spavins, Maxi is spot on. I'm sorry to hear about Mouse Marie - was he/she PTS because of the spavin or was it something else? (Faith has had bone spavin in both hocks, worst on her left hock, and we've worked it so her bones have fused and they don't seem to affect her other than she's a bit stiff in a morning...)
