The effect of adding carboxymethylcellulose and alginate to hyaluronic acid on reducing epidural fibrosis in a lumbar laminectomized rat model.
Objective: This study aimed to compare the anti-epidural fibrosis and anti-inflammation effects of hyaluronic acid (HA)-carboxymethylcellulose (CMC)-alginate hydrogel, pure HA, and normal saline using a lumbar laminectomized rat model.
Methods: Thirty lumbar laminectomized adult rats were randomly assigned to three groups. The control group received normal saline, the HCA group received HA-CMC-alginate gel, and the HA group received pure HA gel soaked over the dura of the laminectomized area before closing the surgical wound. All rats were housed for eight weeks, then epidural fibrosis (EF) was histologically graded. In addition, the fibroblast and inflammatory cell density were computerized for evaluation.
Results: The mean fibroblast densities were 32.03 × 102 ± 488, 13.22 × 102 ± 200, and 14.52 × 102 ± 368 cell/mm2 in the control, HCA, and HA groups, respectively. The mean inflammatory cell density was 30.74 × 102 ± 459, 5.90 × 102 ± 129, and 11.08 × 102 ± 282 cell/mm2 in the control, HCA, and HA groups, respectively. The mean fibroblast and inflammatory cell densities in the HCA and HA groups were significantly lower than in the control group (P < 0.05). The HCA group had a significantly lower inflammatory cell density than the HA group (P < 0.05). The fibrous adherence grading of HCA and HA was significantly lower than the control (P < 0.05).
Conclusion: HA-CMC-alginate gel and HA hydrogels seem to have a better preventative effect on EF than no treatment (control). HA-CMCalginate can exhibit a better anti-inflammatory effect than HA. HA-CMC-alginate can be effective in reducing EF and inflammation after lumbar laminectomy.

Acta Orthopaedica et Traumatologica Turcica (AOTT) is an international, scientific, open access periodical published in accordance with independent, unbiased, and double-blinded peer-review principles. The journal is the official publication of the Turkish Association of Orthopaedics and Traumatology, and Turkish Society of Orthopaedics and Traumatology. It is published bimonthly in January, March, May, July, September, and November. The publication language of the journal is English.
The aim of the journal is to publish original studies of the highest scientific and clinical value in orthopedics, traumatology, and related disciplines. The scope of the journal includes but not limited to diagnostic, treatment, and prevention methods related to orthopedics and traumatology. Acta Orthopaedica et Traumatologica Turcica publishes clinical and basic research articles, case reports, personal clinical and technical notes, systematic reviews and meta-analyses and letters to the Editor. Proceedings of scientific meetings are also considered for publication.
The target audience of the journal includes healthcare professionals, physicians, and researchers who are interested or working in orthopedics and traumatology field, and related disciplines.
