In clinical practice, all injuries, if the wound is relatively deep, such as being cut by a sharp object into the subcutaneous tissue or even damaging the tendons, reaching the muscle tissue, can potentially be infected by tetanus. Wounds inflicted by plastic can also be infected by tetanus. In such deep wounds, Clostridium tetani can easily grow and reproduce. This bacterium can produce a toxin that causes muscle spasms, leading to related clinical symptoms. Therefore, if a plastic injury results in a deep wound, there is a risk of tetanus infection. It is advised that the patient seeks medical attention promptly, undergoes wound disinfection, and receives an injection of tetanus antitoxin to prevent infection.
