Minimally invasive plate osteosynthesis mipo and supercutaneous plating scp techniques for tibial and radial diaphyseal fractures in dogs

Abstract

The study was carried out in 24 dogs of different breeds, sex and body weight ranging from 12 to 29 kgs presented to the Small Animal Orthopaedic Out-Patient Unit of the Madras Veterinary College Teaching Hospital with a history of lameness and clinical symptoms suggestive of radial and tibial diaphyseal fractures. Six cases each of radial and tibial diaphyseal fractures were treated with Minimally Invasive Plate Osteosynthesis (MIPO) and Supercutaneous Plating (SCP) under fluoroscopic guidance. In the present study, automobile accident (45.83%) was the primary cause for the fractures in dogs followed by fall from height (41.67 %), slipped on the floor (8.33 %) and unknown cause (4.17 %). newlineIn the present study, minimally invasive plate osteosynthesis and supercutaneous plating techniques promoted relative stability of the fracture fragments and facilitated early pain-free limb ambulation. MIPO and SCP techniques were technically demanding and required fluoroscopic guidance intraoperatively. The locking compression plate used in this study had a combi hole design that could be used to bring about compression or buttress depending on the fracture configuration without disturbing the fracture environment. The locking compression plate system acted as a single beam construct and promoted secondary bone healing in radial and tibial diaphyseal fractures both with minimally invasive plate osteosynthesis and supercutaneous plating techniques. The operative time in these techniques was reduced when compared to open reduction internal fixation of fractures. Early functional outcomes with minimal postoperative complications were reported in the study. newline
