Biologically Oriented Plate Fixation for Avian Long-Bone Fractures: A Case Series

Avian long-bone fractures are challenging because of the distinctive anatomy and biomechanics of avian bone and the need to preserve local biology while restoring function. The aim of this study was to evaluate the clinical application of biologically oriented plate fixation in avian long-bone fractures. A retrospective descriptive case series was performed using six avian fracture cases with complete records of species, bone, fracture type, fixation method, complications, and radiographic follow-up. The population included two domestic chickens, one peafowl, one hyacinth macaw, one bald eagle, and one sulphur-crested cockatoo. Fractures involved the tibiotarsus (4/6), femur (1/6), and radius/ulna (1/6), with transverse and comminuted configurations. Internal plate fixation was used in all six cases. Radiographic union was achieved in all cases, with healing times of 60–92 days. One femoral fracture treated with a 3.5 mm locking plate was complicated by plate failure; no complications occurred in the remaining cases. Because outcomes were assessed only by radiographic union and documented complications, with no functional outcome data, these findings should be interpreted cautiously. Biologically oriented plate fixation may be a viable option for selected avian long-bone fractures, though larger prospective studies are needed to define indications, construct selection, and outcomes.
