- n. An abnormal swelling (tenosynovitis) on the sides of the hock joint of horses
from the GNU version of the Collaborative International Dictionary of English
- n. A disease of the hock (sometimes of the knee) of a horse, caused by inflammation of the synovial membrane and a consequent excessive secretion of the synovial fluid; -- probably so called because there is usually an oval swelling on each side of the leg, appearing somewhat as if a pin had been thrust through.
from The Century Dictionary and Cyclopedia
- n. A swelling in the hollow of the hock of the horse, appearing on both inner and outer aspects, and caused by distention of the synovial sheath of the flexor perforans tendon playing over the side of the joint; also, a similar swelling on the posterior aspect of the carpal joint, or so-called knee of the fore leg.
The dilatation of this articular synovial sac is what is denominated bog spavin, the term thoroughpin being applied to the dilatation of the tendinous capsule.
Thus it seems that subjects of rather faulty conformation, animals having lymphatic temperaments and the coarse-bred types, are prone to synovial disturbances such as thoroughpin, bog spavin, etc., sometimes having both legs affected.
In fact, spontaneous relief from lameness usually results in the course of ten days 'time following the appearance of thoroughpin.
[Illustration: Fig. 58 -- Fibrosity of tarsus as a complication in chronic thoroughpin.]
Bog spavin is often present in case of thoroughpin but the two conditions are separate and distinct excepting in that both may occur simultaneously and as the result of the same cause.
Treatment of thoroughpin by aspiration and injection, 250
The thoroughpin is found at the back and on the top of the hock in that part known as the "hollows," immediately behind the shank bone.
A thoroughpin is an bursa (fluid filled cavity) on the hock, and can usually be 'pushed' through to the other side of the hock.
hi can anyone here tell me the difference between thoroughpin and a splint?
