Abstract
An automatic oximeter has been developed to determine at the time of initial operation
which femoral head is alive and which is dead. The accuracy of prediction of avascular
necrosis by the measurement of oxygen transport is in the same range of accuracy as
several radioisotope methods, namely, 90 per cent or better. The instrument provides
a safe, easy method for use in any local hospital, to determine whether the subcapital
fracture should be reduced and pinned or whether further specific measures should
be taken in the case of an avascular head.
Experimental evidence indicates that displacement or volvulus of a subcapital fracture
in dogs results in a vascular obstruction. If unrelieved, the anoxia leads to infarction
of the bone in all cases within 12 hours, and in 50 per cent of cases, within 6 hours.
This experimental proof of a dynamic factor of vascular occlusion and a time limit
for anoxia of bone may have a direct bearing on the emergency treatment of displaced
subcapital fractures in the human.
