Steinmann implant migrated removed by videolaparoscopy in dog / Videolaparoscopia na remoção de pino de Steinmann migrado em canino

ABSTRACT

Background: For the stabilization of vertebral fractures and luxations are proposed various techniques, with an association of Steinmann pins and bone cement preferred. Implant failure or migration can occur as a late complication of spinal stabilization as well as breaking pins and cerclage wires. The actual incidence of migration of metallic fixation pins and wires is unknown, although the complication has been well documented being sometimes even associated with the death of the patient. The present report aims to describe the use of laparoscopy in removing a Steinmann pin the muscles of the abdominal wall, adjacent to the peritoneal cavity in a dog. Case A canine mixed breed, female, 1.5 years old, was attended with a history of hit by motor vehicles and after medical and neurological examination was submitted to radiographic examination, evidencing fracture and dislocation of the sixth lumbar vertebra, with cranio-ventral displacement the caudal fragment of the body of the sixth lumbar vertebra. Then underwent surgery to stabilize the spine. For that, was elected segmental spinal fixation modified by applying pins and cerclage wires on spinous processes and facet joints to stabilize the vertebral segments. Two months after the stabilization column radiographic examination control was observed the presence of radiopaque metallic structure, located between L2-L3 in the left...(AU)
