ing caught in the fissure and
perforation of its wall may result. Such a case is reported by
Bauman[36] wherein a three-year-old gelding bore the history of having
been lame for ten days. Upon rectal examination the bladder was found to
be hard and tumor-like and about the size of a baseball. The body of the
ischium in this case was fractured and a rent in the bladder was caused
by a sharp projecting piece of bone. Autopsy revealed, in addition to
the fracture and rent of the bladder wall, a large quantity of urine in
the peritoneal cavity.

In other instances hemorrhage caused death and not infrequently
infection was responsible for a fatal issue. Moller,[37] quoting Nocard,
describes a case where fracture occurred through the region of the
foramen ovale and paralysis of the obturator nerve followed.

Fractures which include the acetabular bones cause great pain. This is
manifested by marked lameness, both during weight bearing and when the
member is swung. Such cases terminate unfavorably--complete recovery is
impossible.

Where small portions of the angle of the ilium are broken, and the skin
is left intact, there exists the least troublesome class of pelvic
fracture. If large portions of the ilium are fractured, considerable
disturbance results. There eventually occurs more or less displacement
in such cases, if such displacement does not take place at the time of
injury. The same may be said of fracture of the tuber ischii, but when
these bones are fractured a more serious condition results.

Treatment.--When a case is found to be uncomplicated, that is, if the
fracture is such that recovery seems possible and after having
determined that treatment may be practicable, the first consideration is
that of confining the subject in suitable slings. In many cases of
pelvic fracture, the affected animal will need to be kept in slings from
six weeks to three months, and it becomes a difficult problem to
minimize the distress during this long period of confinement in the
peculiar manner required for favorable outcome.

The pattern of sling employed should be the best that is obtainable and
the matter of its adjustment is quite important lest unnecessary chafing
or even necrosis of skin result. Frequent readjustment may be necessary,
and time is well spent in this manner since this contributes materially
toward a favorable termination by encouraging the subject to remain
quiet so that coaptation of the broken bones may
