Standard Surgical Technique for Applying Rod Through Plate (RTP) Internal Fixator – An Experimental Study in Sheep
The standard surgical technique for applying a rod through plate (RTP) internal fixator to treat long bone fractures was carried out. The experiments were performed in 4 male Estonian Blackhead sheep. Previously, a RTP fixator for small animal fracture repair has been tested experimentally in rabbits and also on clinical cases in dogs. To reduce complications such as screw loosening and rod displacement, modification to the original fixator was made: one locking screw on each rod was added to fix the rod to the plate. In this study the healing process of tibial osteotomies using the modified RTP fixator was evaluated in sheep. Sheep were used as experimental animals because body weight and bone structure is similar to small animals.
