Most cats with surgically repaired spinal fractures walk again within 8 weeks

A retrospective study of 30 cats found 28 ambulatory at 8 weeks and 23 fully recovered long-term, with owner assessment good or excellent in 27 of 29.

A retrospective study of 30 cats that underwent surgical stabilization of vertebral fractures or luxations found that 28 were ambulatory at 8 weeks postoperatively, and 23 fully recovered in the long term.

What the study found

The study enrolled cats that had surgery for vertebral fractures and luxations without prior neurological disease, from March 2012 to December 2024. Injury locations were lumbar in 16 cats, thoracic in 9, lumbosacral in 4, and cervical in 1. Before surgery, "preoperative modified Frankel scores were grade 3" in 12 cats, grade 4 in 8, grade 2 in 4, grade 5 in 2, and grade 1 in 1, according to the study. "At 8 weeks postoperatively, 28 cats were ambulatory," the study reports. Long-term, the study found that "23 cats fully recovered. Grade 5 cats did not show neurological improvement. Among the 28 long-term ambulatory cats, 6 had persistent proprioceptive ataxia and all of these had T3-L3 neuroanatomical lesions. Urinary incontinence persisted in 4 cats." The study reports that "owner assessment of long-term neurological recovery was good or excellent in 27 of 29 cats."

How the study was built

This was a retrospective observational study conducted at one institution over the study period. The authors collected data from clinical and radiographic follow-up and telephone surveys. The study reports that "surgical stabilization techniques primarily involved polymethylmethacrylate with screws" in 18 cats or pins in 9. The study tracked modified Frankel score progression, urinary incontinence, and owner-reported outcomes. Because this is a retrospective design from a single hospital, it describes what was associated with recovery in this population but cannot prove that surgery was responsible for the improvement, and the results may not generalize to other settings or surgical techniques.

The number, and its error bars

Twenty-eight of 30 cats were ambulatory at 8 weeks postoperatively, and 23 of 30 fully recovered in the long term. The abstract does not provide confidence intervals, p-values, or statistical comparisons. Six of the 28 long-term ambulatory cats had persistent proprioceptive ataxia, and 4 cats had persistent urinary incontinence. Owners rated recovery as "good or excellent in 27 of 29 cats," the study reports. The authors conclude that "surgical management was associated with favorable neurological recovery, even when surgery was delayed or postoperative reduction was incomplete."

What the authors say it cannot tell you

The abstract does not state specific limitations. That absence is itself a limitation, because the reader does not know what confounders the authors considered, whether surgical technique or timing affected outcomes, or how many cats were lost to follow-up. The study also does not report how long term was defined or how many cats reached each follow-up interval.

Who paid for it

The abstract does not state funding sources or conflicts of interest.

What this means for your practice

VeterinaryPracticeNow's read, not the study's. Everything in this section is our editorial interpretation for practice owners. The study does not claim any of it.

This gives you a timeline and a success rate to cite when an owner asks whether surgery is worth it after a car strike or high-rise fall. Most cats in this series were walking by the two-month mark, and most owners rated recovery as good or excellent, which matters as much as the Frankel score in the prognosis conversation. The study does not tell you which surgical technique to recommend or whether delaying surgery changes the outcome, but it does tell you that incomplete reduction did not preclude recovery in this series.

The urinary incontinence data is the part that changes quality-of-life counseling. A subset of cats had persistent incontinence, and another subset had persistent ataxia despite regaining walking. If you are referring a spinal trauma case, those are the two outcomes that determine whether the owner considers the surgery successful, and now you have a rate to cite.

The study does not break out outcomes by injury location or preoperative Frankel score in the abstract, so we cannot tell an owner that a lumbar fracture has better odds than a thoracic one. The authors state that nociception must be preserved for surgery to be considered, which is the clinical gate most of us already use, but the study does not quantify how many cats without nociception were excluded.
