Short- and long-term success of transfixation pin casts used to stabilize long bone fractures in ruminants.

Transfixation pin casts (TPC) may be useful in management of fractures in ruminants. A retrospective study was conducted to report the uses, complications, and outcomes of TPC in ruminant fracture stabilization. Twenty-five cattle, 7 goats, and 7 sheep with long bone fractures managed with TPC met the inclusion criteria. Long-term outcome was assessed from telephone interviews with owners. Thirty-one animals (79%) survived to removal of external coaptation and return to the farm. Common complications included pin-hole osteitis and disuse osteopenia. Common complications resulting in death or euthanasia included osteomyelitis and non-union and pin tract fracture. Animals with increased body weight had a greater odds of dying or being euthanized. Cattle had a decreased odds of dying or being euthanized compared with goats and sheep. Long-term follow-up was available for 20 patients, 17 of which returned to intended use and 12 of which had no residual lameness.
