What Are the Hazards of Leaving Titanium Alloy Steel Pins Unremoved?

If titanium alloy steel pins are not removed in a timely manner, common hazards include complications. Prolonged placement can easily lead to fractures and osteoporosis due to pin breakage. Additionally, there are significant hazards in daily life, such as causing issues during security checks. Long-term placement may also result in rejection reactions. Here are some specific hazards:

1. Causing Complications: Prolonged placement of steel pins inside the body can lead to various complications. For instance, the pins may experience fatigue and even break, causing stress shielding at the fracture site, which can lead to osteoporosis.

2. Inconvenience during Security Checks: The presence of steel pins can cause inconvenience during security checks, as they may trigger alarms, leading to explanations and potential delays. However, with a medical certificate from a hospital, most situations can be resolved without issue.

3. Rejection Reactions: There is a possibility of rejection reactions to the internal fixation, which can result in loosening of the fixation and even protrusion of the pins under the skin. However, this scenario is clinically rare.

4. Severe Fracture Damage: In cases of severe trauma, the presence of steel pins can exacerbate the fracture damage. The leverage effect of the internal fixation may enlarge the fracture area, leading to more severe fractures.
