Volume of the Synovia in Certain Joint Cavities in the Horse

Synoviavolymen i vissa ledkaviteter hos häst


A method of determining the volumes of synovia in certain articular cavities in the horse is described. The method is based on the degree of dilution of human serum albumin labelled with 125I that is injected into the joint. It is shown that uniform distribution of the injected substance is attained within 20 min post injection. The elimination of the labelled substance was found to follow the pattern of a single exponential function. The following volumes of synovia were determined (mean ± s) : hock, 39.8 ± 2.1 ml; radio-carpal, 12.6 ±1.5 ml; intercarpal, 14.9 ± 0.6 ml; foreleg fetlock joint, 12.5 ± 1.0 ml.


En metod för att bestämma synoviavolymen i vissa ledkaviteter hos häst beskrives. Metoden baseras på utspädningen av humant serumalbumin markt med 125I som injiceras i leden. Det visas att den märkta substansen är jämnt fördelad i leden 20 min efter injektionen. Eliminationen av det märkta albuminet kan beskrivas matematiskt som en enkel exponentiell funktion. Följande synoviavolymer uppmättes: has, 39,8 ± 2,1 ml (Medeltal ± s) ; radio-carpal, 12,6 ± 1,5 ml; intercarpal, 14,9 ± 0,6 ml, kotled, framben, 12,5 ± 1,0 ml.
