- Abstract
The objective of the present study was to describe and evaluate the midventral approach to the lumbar spine and stabilization using Polymethyl methacrylate and pins. Six dogs presented with a history of traumatic posterior paralysis and diagnosed to be suffering from lumbar vertebral fracture and luxations by detailed clinical, neurological, radiographic and myelographic examinations were taken for the study. All dogs were subjected to mid ventral celiotomy and the ventral surface of the fractured lumbar vertebrae was reached in between the Psoas minor muscles. Two pins were inserted bicortically and diagonally at an angle of 45°-55° from either side of the mid sagital plane, in opposite directions across the body of each adjacent vertebra on either side of the fractured vertebra. The pins were bent and cut to the required length. The fracture was stabilized using Polymethyl methacrylate + Gentamicin + Iohexol mould by incorporation of all four pins. Pre and Postoperatively Amoxicillin clavunate, Meloxicam, Neurotonics and Vitamine-E were administered along with physiotherapy. All animals had complete neurological recovery and radiographically there was complete bony union by 60 days postoperatively. Computer tomographic evaluation revealed no violation of the vertebral canal. To conclude, this technique has several advantages like minimal dissection and bleeding, better visualization of the fracture site, more working space, ease of correct placement of implants into the body of vertebrae along the safe corridors, better bony purchase and anchorage of implants, preservation of blood supply, avoids entry into the spinal canal and or intervertebral disc space and overall gave stability to fracture site and better outcome.
