Ex Vivo Biomechanical Comparison of Four Techniques to Tibiotarsus Osteosynthesis in Adult Laying Hens (Gallus gallus domesticus).

Objective:  To assess the biomechanical parameters of intact tibiotarsi (INT) and tibiotarsi with a 5-mm segmental diaphyseal defect repaired using four osteosynthesis techniques: a locking plate (LP), a plate-rod combination, an external skeletal fixator (one end-threaded positive-profile pin per fragment) with an intramedullary pin tie-in (TIF 1), and an external skeletal fixator (two end-threaded positive-profile pins per fragment) with an intramedullary pin tie-in (TIF 2).

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.
