When cow saliva improves... surgery

Medical innovation is inspired by nature. A synthetic gel, derived from bovine saliva, could revolutionize herniated disc surgery. This intriguing discovery raises questions about the future of post-operative treatments.

Herniated discs affect a significant portion of the population, leading to pain and complications. Currently, managing these conditions relies on treatments that often do not address the underlying issues. Researchers at Uppsala University are proposing a promising alternative.

The treatment of a herniated disc typically occurs in two stages. Initially, efforts are made to alleviate symptoms without resorting to surgery. Painkillers, anti-inflammatory drugs, and steroid injections are commonly used, combined with physiotherapy sessions to reduce pain and improve mobility.


However, if symptoms persist after several weeks of conservative treatment, surgery becomes an option. It involves removing the portion of the herniated disc that is compressing the nerves. Yet, this intervention is considered a last resort, as it carries risks and may not prevent future complications, particularly immune system attacks on the remaining disc tissue.

Research conducted at Uppsala University has revealed that mucin gel, inspired by parasitic mucus, acts as an immune barrier. This innovation could reduce the risk of post-surgery complications, particularly by preventing immune cell attacks on the surrounding tissues. The gel, administered via injection, solidifies within minutes.

Preliminary results are encouraging. In animal models, the injection of the gel preserved the biomechanical properties of the intervertebral discs, unlike conventional treatments. The models treated with the gel showed prevention of degradation up to 24 weeks after surgery.

However, transitioning to clinical practice requires further study. The research team plans to explore the gel's efficacy in larger models and test its behavior under different mechanical loads. This work is crucial in confirming the gel's applicability in real-world conditions.

This method could transform the standard of care for patients suffering from herniated discs. A simple injection of this gel could significantly improve surgical outcomes and reduce post-operative pain. The promise of a better quality of life for patients is at the heart of this research.

Thus, this advancement could signal a turning point in the treatment of herniated discs. Inspiration drawn from nature is opening new avenues in the fight against pain and surgery-related complications.

What is a herniated disc?

A herniated disc occurs when the intervertebral disc, located between two vertebrae, deteriorates or shifts. This leads to the compression of a nerve, causing intense pain and sometimes loss of mobility. The disc consists of two parts: a soft jelly-like center and a tougher, fibrous outer layer.

The pain arises from the compression of the nerves around the spinal cord. When the soft center of the intervertebral disc bulges out from the fibrous outer layer, it can press on the nerves, causing pain that radiates into the limbs and back.
