Fibular and metatarsal osteosynthesis in a southern brown howler monkey (Alouatta guariba clamitans )

Here we describe a successful surgical management of a distal fibular fracture combined with a tarsocrural luxation and multiple metatarsal fractures in the left foot of a southern brown howler monkey ( Alouatta guariba clamitans ). We achieved satisfactory outcome by applying intramedullary pinning for each of the bone fractures and closed reduction of joint luxation—kept in place only by bone alignment, without further ligament reconstruction. Bone healing occurred uneventfully within eight weeks and the monkey's foot regained its normal function. Therefore, we could properly release the patient back into the wild.
