Lumbar and lumbosacral pain in dogs often involves multiple concurrent spinal pathologies, complicating the identification of primary pain generators. This study assessed the associations between MRI-diagnosed spinal pathologies and pain to provide clinically relevant insights for their diagnosis and management. MRI scans and clinical records of 518 client-owned dogs were retrospectively reviewed, documenting demographic data, pain status, and MRI findings. Multivariable logistic regression models evaluated the associations between spinal pathologies and pain, adjusting for age and weight. The intervertebral disc (IVD) extrusion was the primary pathology associated with lumbar pain, while radiculopathy had the strongest association with lumbosacral pain. Additional lumbosacral pathologies, including foraminal stenosis, IVD bulging, and IVD protrusion, were also significantly associated with pain. However, some dogs with MRI-diagnosed abnormalities showed no pain, whereas others with pain had no detectable MRI pathology, underscoring the need to interpret imaging within the clinical context. Pain responses observed during physical examination often overlapped between spinal and hip conditions, complicating diagnostic accuracy. These findings emphasise the importance of integrating imaging, clinical assessment, and targeted diagnostic techniques to improve pain localisation and treatment decisions, providing veterinarians with valuable data to refine the management of lumbar and lumbosacral pain in dogs.

Traditionally, canine degenerative lumbosacral stenosis (DLS) has been defined as a multifactorial syndrome characterized by lumbosacral pain triggered by the compression of the nerve rootlets of the cauda equina. There is still no consensus on the treatment of this condition, probably because there are a plethora of possible causes. In addition to compression, inflammation is a very important factor in the physiopathology of the disorder. Platelet-rich plasma (PRP) consists of an increased concentration of autologous platelets suspended in a small amount of plasma. Platelets are a source of several growth factors. Growth factors were shown to help in wound healing and biological processes, such as chemotaxis, neovascularization and synthesis of extracellular matrix, and growth factors were used to improve soft tissue healing and bone regeneration. PRP also facilitates the restoration of the structural integrity of the affected anatomy. Fourteen dogs diagnosed with DLS were treated with three epidural injections of PRP on days 0, 15 and 45. All dogs showed clinical improvement 3 months after the initial treatment. Gait was also objectively assessed by means of the use of force platform analysis before and after treatment, showing significant improvement. The results show that PRP may provide a good alternative to other nonsurgical treatments, such as prednisolone epidural injection. Full article
