Violino classico, dettaglio

Catgut is a type of cord or string that was traditionally made from the natural fibers of the intestines of animals, most commonly sheep, goats, and sometimes cattle. Despite its name, catgut did not originate from cats. The term "catgut" may have been derived from the word "kitgut" or "kitstring" - the string used on a kit, which was a small fiddle. Catgut has been used for centuries in various applications, including as sutures in surgery, strings for musical instruments such as violins, violas, cellos, and double basses, and for tennis rackets and archery bows.

History

The use of catgut for surgical sutures dates back to the ancient Egyptians, but it became more widespread with advancements in sterilization techniques in the 19th century. In the realm of music, catgut strings were the primary choice for stringed instruments until the 20th century when steel strings and synthetic materials began to replace them due to their consistency and durability. The manufacturing process of catgut involves cleaning the intestines, splitting them into strips, and then twisting these strips into cords of various thicknesses. The cords are then dried, polished, and sometimes treated with chemicals to increase their longevity and performance.

Medical Use

In medicine, catgut was primarily used as a material for absorbable sutures. There are two main types of catgut sutures: plain and chromic. Plain catgut is untreated and is absorbed by the body relatively quickly, making it suitable for surgeries where fast healing is expected. Chromic catgut is treated with chromium salts to slow down its absorption rate, making it suitable for use in tissues that heal more slowly. However, due to the potential for causing inflammatory reactions and the development of more advanced synthetic materials, the use of catgut in medical sutures has significantly declined.

Musical Instruments

In the manufacturing of strings for musical instruments, catgut offers a unique tone that is difficult to replicate with synthetic materials. The elasticity and density of catgut produce a warm, rich sound that is highly valued, particularly in baroque and classical music. Musicians who specialize in historical performance practice often prefer catgut strings to preserve the authentic sound of the period.

Modern Alternatives

Today, the use of catgut has largely been supplanted by synthetic materials in both the medical and musical fields. Synthetic sutures, made from materials such as polyglycolic acid, polylactic acid, and polydioxanone, offer greater strength, less risk of infection, and more predictable absorption rates. In the world of music, synthetic strings designed to mimic the properties of catgut, such as nylon and perlon, are widely used due to their durability, stability in varying climatic conditions, and ethical considerations.

Ethical and Cultural Considerations

The production of catgut has raised ethical concerns, particularly regarding animal welfare and the use of animal products. The shift towards synthetic alternatives reflects not only advancements in technology but also a growing awareness and sensitivity towards these issues. Additionally, the unique cultural and historical significance of catgut in various fields continues to be a point of interest for researchers, musicians, and medical professionals alike.
