AbstractBackgroundThoracolumbar intervertebral disc extrusions (TL‐IVDEs) are a common spinal disorder in dogs, especially within chondrodystrophic breeds. Loss of deep pain perception is a well‐documented negative prognostic indicator in dogs with TL‐IVDE. The objectives of this study were to report the rate of return of deep pain perception and independent ambulation in surgically treated, paraplegic, deep pain perception negative French bulldogs with TL‐IVDEs.MethodsA retrospective case series of deep pain perception negative dogs with TL‐IVDE presenting to two referral centres between 2015 and 2020 was conducted. Medical and MRI records were reviewed, including the following quantitative MRI changes: lesion length, extent of spinal cord swelling and severity of spinal cord compression.ResultsThirty‐seven French bulldogs met the inclusion criteria, with 14 of 37 (38%) regaining deep pain perception by the time of discharge (median hospitalisation 10.0 days [interquartile range 7.0–15.5 days]) with two dogs independently ambulatory (6%). Ten of the 37 dogs were euthanased during hospitalisation. Significantly fewer dogs (3/16, 19%) with L4‐S3 lesions regained deep pain perception compared to 11 of 21 (52%) of dogs with T3‐L3 lesions (p= 0.048). Quantitative MRI changes were not associated with the return of deep pain perception. After discharge, with a median 1‐month follow‐up period, an additional three dogs regained deep pain perception and five dogs became independently ambulatory (17/37 [46%] and 7/37 [19%], respectively).Conclusions and clinical importanceThis study adds support to the contention that the recovery of French bulldogs with TL‐IVDE from surgery is poor compared with other breeds; further prospective, breed‐controlled studies are indicated.
