Abstract
Clinical tests with the prototype 4.5 mm PC-Fix system were conducted in large animals
suffering long bone fractures due to trauma. Initial interfragmentary fixation of
the fractures with cortex screws inserted as lag screws was followed by the application
of two plates at right angles to each other. The 4.5 mm PC-Fix plates and screws were
used in horses and cattle. In newborn animals, the 3.5 mm PC-Fix was used. In most
cases some type of external coaptation was applied to reduce the danger of fixation
breakdown during the immediate postoperative period.
Of the 24 fractures treated with the PC-Fix, 18 healed which represents a success
rate of 75%. Good or excellent results were achieved in cattle where 13 out of 15
(86.6%) fractures healed in a relatively short time. The fractures healed in only
5 of the 9 horses (55.5%). The percentages are similar to, if not somewhat better
than those for conventional internal fixation techniques. The reasons for the failures
are discussed.
The results of the study revealed that the 4.5 mm prototype, and in selected cases
the 3.5 mm PC-Fix systems were viable options for the treatment of long bone fractures
in large animals.
