The effect of halofuginone use on epidural fibrosis after spinal surgery: An animal experiment – Lumbar Spinal Stenosis

The article explores the effectiveness of local halofuginone application in preventing epidural fibrosis (EF) after spinal surgery in rats. The study divided rats into four groups and found that fibrosis was significantly lower in the group that received halofuginone compared to the control group. However, there was no significant difference in fibrosis between the groups that received spongostan or halofuginone-impregnated spongostan and the control group. The study concludes that halofuginone may help prevent EF after spinal surgery, but further research is needed to evaluate its safety in humans

ABSTRACT

AIM: Epidural fibrosis (EF) can cause persistent low back pain after spinal surgery. Type I collagen is the main component of scar tissue formed after spinal surgery, and an antifibrotic agent is necessary for preventing fibrosis. Halofuginone is an antifibrotic agent that has an effect on type I collagen. Our study aimed to investigate the effectiveness of local halofuginone application for spinal EF after lumbar laminectomy in rats.

MATERIAL AND METHODS: Forty rats were equally divided into four groups (Groups I-IV; 10 rats in each group), and lumbar laminectomy was performed under general anesthesia. After laminectomy, Group I received saline (NaCl 0.9%) locally (control), Group II received spongostan, Group III received 0.5 mL of halofuginone-impregnated spongostan, and Group IV received 0.5 mL of halofuginone. Spongostan was used to prolong the exposure period of halofuginone. All rats were sacrificed after four weeks and evaluated according to histopathological criteria. A p-value of 0.05 was considered statistically significant.

RESULTS: Fibrosis was significantly lower in Group IV than in Group I (p 0.05). There was no significant difference in fibrosis between Group II/III and Group I. It was observed that spongostan increased fibrosis.

CONCLUSION: Halofuginone helps prevent EF after spinal surgery. However, further clinical and experimental studies are needed to assess its safety in humans.
