Nonsurgical Rehabilitation in Dachshunds With T3-L3 Myelopathy: Prognosis and Rates of Recurrence

Abstract

Dachshunds are at significant risk of experiencing thoracolumbar intervertebral disk herniation (IVDH) during their lifetimes. Standard of care includes advanced imaging, surgical intervention, and postoperative rehabilitation. Conservative management is commonly recommended for cases where the standard of care is declined, and little is known about the prognosis of treatment with conservative management and rehabilitation (nonsurgical rehabilitation). This retrospective cohort study assessed 12-week functional outcome and recurrence of clinical signs in 40 dachshunds with T3-L3 myelopathy presumed to be due to Hansen's Type I disc herniation, treated with nonsurgical rehabilitation. The overall prognosis was good with 34 of 40 (85.0%, 95% CI 70.2–94.2) dachshunds achieving functional pet status by 12 weeks postinjury. Modified Frankel Score at presentation was significantly (p < 0.001) higher in dogs with a positive 12-week outcome compared to dogs that did not recover by 12 weeks. All 27 dogs with motor function at presentation had a positive outcome. Of the 9 dogs exhibiting paraplegia with intact deep nociception at presentation, 7 dogs (77.8%) had achieved a positive outcome by 12 weeks. None of the 4 dogs persistently lacking deep nociception had a positive outcome. Among 27 dogs with a positive outcome for whom follow-up records were available, the 1- and 2-year recurrence rates for T3-L3 myelopathy were 5 and 11%, respectively. Nonsurgical rehabilitation should be considered in dachshunds with mild to moderate T3-L3 myelopathy or in severe cases when advanced imaging and surgical intervention are not possible.

Comparative analysis of post-operative rehabilitation approaches for medial patellar luxation in small-breed dogs

“…In recent years, there has been a growing interest in companion animal rehabilitation in the field of veterinary medicine [8,11,22]. This study focuses on both primary rehabilitation management and post-operative rehabilitation approaches [9,14,23,24]. In primary management, the emphasis of rehabilitation is on enhancing the animal's physical functionality and alleviating any associated pain [12].…”

Recurrence of clinical signs following treatment for intervertebral disc extrusion: what is really going on?

“…Several factors could potentially help reduce this financial burden, including increasing awareness of the potential for recovery with medical management alone 5 and the more routine adoption of prophylactic procedures such as disc fenestration, 3 laser disc ablation 6 or chemonucleolysis 7 . Reducing the frequency of the disease within predisposed breeds would also help reduce the need for treatment in the long term.…”
