Abstract by Jon Miles
Two cases of tuberculosis of the coccyx are discussed, with symptoms of pain on sitting and in one case pain on rising from sitting. In both cases the coccyx was removed, resulting in relief of the symptoms. In one case a sinus in the skin over the coccyx, leading to a pocket of pus, was found. This suggests that this may have been a pilonidal sinus (not discussed in the paper). The paper is also of interest in demonstrating a use of terminology: the coccyx is referred to at one point as 'the lower two segments of the sacrum'.
