Physical examination and radiogram revealed comminuted fracture of left tibia with cranially displaced bone fragments. Plate-rod technique of biologic osteosynthesis was performed with adjunct therapy of engraftment of autologous platelet rich plasma seeded hydroxyapatite which provided better clinical outcome without post-operative complication and early ambulation. Plate-rod technique of biologic osteosynthesis in combination with engraftment of autologous platelet rich plasma seeded hydroxyapatite for the management of tibial fracture improved the clinical outcome in a Black buck.

In free-ranging ruminants among the non-infectious diseases, fracture constitutes a major reason for mortality (Mboera and Kitalyr, 1992). Tibial fracture is predominant in small ruminants among the long bone fractures (Gahlod et al., 2012). Fracture treatment in wild and free-ranging animals pose a challenge for veterinary surgeon as the
