Abstract
Traumatic lumbosacral joint dislocation (TLSJD) without L7 vertebral body fracture is a rare injury in dogs. This report describes clinical presentation, therapy and outcome in 3 dogs. Three crossbreed dogs with non-ambulatory paraparesis and lumbar pain were referred. Radiographs confirmed TLSJD and dorso-ventral displacement (DVD) was measured pre and postoperatively. Case 1 was treated by percutaneous transilial pinning. Cases 2 and 3 were treated by internal fixation with pins and PMMA. Within 72h after surgery all dogs were able to stand and walk, and faecal incontinence resolved. To the author’s knowledge this is the first description of a case series of TLSJD in the dog. The biomechanics of TLSJD in animals have not been investigated. It is likely that a single trauma severely hyper-extends L7-S1 causing disruption of the supra and inter-spinous ligaments with simultaneous shear and compression forces that cause ventral slipping of the sacrum. Pins and PMMA compared to percutaneous transilial pinning, provided more strength and stability. In conclusion, TLSJD requires appropriate surgical reduction and stabilization to allow fibrous healing of the L7-S1 junction, resulting in satisfactory neurological recovery
