Objective—To evaluate long-term outcome of repair
of femoral capital physeal fractures with 7.0-mm cannulated
screws in juvenile bulls that weighed > 350 kg
Procedure—Medical records of affected cattle were
identified and reviewed. Follow-up information was
obtained by means of a written questionnaire, 1 to 15
years after discharge, from the veterinarians who
supervised the postoperative care at bull stud facilities.
Results—Mean age and body weight at time of repair
were 19 months (range, 11 to 27 months) and 513 kg
(1,128.6 lb; range, 364 to 720 kg [800.8 to 1,584 lb]),
respectively. Surgical repair was performed with 7.0-
mm cannulated screws. A second surgery to replace
malpositioned implants was required in 1 bull. Fourteen
of the 20 bulls were considered serviceable for semen
collection after surgical repair, and persistent lameness
was evident in 11 of the 14. Mean duration for bulls to
become serviceable was 5.5 months (range, 2 to 11
months). Age, weight, duration of injury at the time of
repair, and degree of reduction did not have a significant
effect on whether surgical repair was successful. Six
bulls remained severely lame and were euthanatized.
Conclusions and Clinical Relevance—Results indicated
that surgical repair of femoral capital physeal
fractures in adolescent bulls with 7.0-mm cannulated
screws placed in lag fashion has a good prognosis for
long-term function in a semen collection facility.

Objective—To describe signalment; surgical findings; short-, medium-, and long-term outcome; and recurrence rate for cattle undergoing celiotomy because of jejunal hemorrhage syndrome (JHS) and to analyze risk factors associated with outcome and recurrence.
Design—Retrospective case series.
Animals—31 dairy cattle with JHS.
Procedures—Medical records were analyzed. Follow-up information was obtained from owners of cattle surviving until discharge.
Results—18 of 31 (58%) cattle undergoing celiotomy survived to initial discharge. Fifteen (48%) and 13 (42%) were alive 6 and 12 months after discharge, respectively. All 5 deaths within 12 months after discharge were attributed to JHS recurrence. Survival time was 12 to 85 months for the 13 long-term survivors. Six of 7 that died > 12 months after celiotomy did so for reasons unrelated to JHS. Recurrence rate among short-term survivors was 7 of 18; 1 of these survived long-term. A significant proportion of affected cattle were Brown Swiss, compared with proportions for other breeds. Manual massage of the bowel to break down clots was associated with a significantly higher short-term survival rate than was en-terectomy or enterotomy. Medium- and long-term survival rate was higher in cattle referred 24 to 48 hours after onset of signs. Length of obstructing blood clots was not associated with outcome. Other factors were not significantly associated with recurrence.
Conclusions and Clinical Relevance—Survival rates were higher than those in other reports. Prompt celiotomy and resolution by use of manual massage were associated with higher survival rates. In this population, JHS recurred in 7 of 18 short-term survivors.
