This study was carried out on 19 dogs of different breed, age and sex. 10 different types of radius-ulna and 9 tibia fractures were treated by circular external skeletal fixator. The cases were followed by clinical and radiological controls in the postoperative period. It was observed that the cases tolerated the apparatus well. There was no looseness of fixator stability and configuration during the 15-day interval examination. Complications like pin track, serous drainage and pin loosening were observed postoperatively. It was concluded that radiographic, clinical and anatomical data together with good preoperative planning, the Ilizarov Method and circular external skeletal fixator was successful for the treatment of open or closed fragmented radius-ulna and tibia fractures in dogs.
The management of comminuted tibial fractures is a challenging problem in small animal orthopedics. External skeletal fixators with Maynard clamps and Schanz pins are commonly used for the osteosynthesis of such fractures. The aim of this study was to perform a clinical assessment of Schanz pins with type 11 frame external fixators in the treatment of comminuted tibial fractures, and the possibility of pin changing when osteolysis and pins loosening appear using Maynard clamps. Schanz pins and external fixators were applied in five dogs. The healing of the treated tibia bones was noted in all cases. Radiological signs of osteolysis, pin loosening and pin tract discharge were observed in two dogs. The results obtained indicate that Schanz pins with type II frame external fixators are reliable and easily manageable. It was also ascertained that Maynard clamps are especially useful for quick pin changing.
The summary describes a clinical case of a four-year-old American Quarter Horse gelding presented for evaluation of a grade 2-3 (2-3/5) lameness of the right hind limb. The patient underwent a thorough clinical and orthopaedic examination including limb flexion tests and diagnostic anaesthesia. Intra-articular anaesthesia of the stifle joint was impossible because of the uncooperative behaviour of the horse. However, provocation tests and radiographs proved diagnostically inconclusive. Therefore, magnetic resonance imaging of the right stifle was performed, revealing a tibial fissure fracture. The result was diagnostic and surprising, considering the degree and chronic nature of the lameness. Based on the findings of magnetic resonance imaging, the horse underwent surgery by the locking compression technique to restore full limb function. All implants were removed six months after surgery. The gelding returned to training without any signs of lameness.
