Thorough-pin is a bursal enlargement situated on the inferiorlateral aspect of the thigh and upper and posterior part of thehock, arising from disease of the tendon of the ilexor pedis per-forans muscle, which is enclosed in a synovial sheath, on theinner side of the os calcis, or from dropsy of the sheath, withoutdisease of the tendon.

The fluid which iills it may, by pressure,be forced from one side to the other; hence the term thorough-pia, or rimning through from side to side. This may bedescribed as true thorough-pin, in contradistinction to thatassociated with very large bog-spavins. A thorough-pin, however large, does not cause bog-spavin, asthere is no real channel of communication between the true hock-joint and the bursa of the perforans tendon; but the capsule ofthe joint swells upwards and backwards, bulges into the bursaof the tendon, and a large bog-spavin may thus cause the
