The Least Destructive Stab Wound: Anatomy and Survivorship

Stabbing injuries can be extremely serious and potentially life-threatening. They can damage vital organs, blood vessels, or nerves. However, if we consider the anatomy of the rib cage and the areas that might be less likely to cause significant damage, we can make some general observations. This article explores the factors that determine the potential severity of a stab wound and the anatomy involved.

Understanding Rib Anatomy and Vitals

In adults, ribs are numbered 1 to 12. The upper ribs are more closely associated with the lungs and major blood vessels, providing more protection to vital organs. The lower ribs, particularly ribs 11 and 12, are often less protected due to their more lateral and mobile nature.

Ribs 11 and 12: Floating Ribs

Ribs 11 and 12 are referred to as floating ribs because they attach to the liver or directly to the spine, not to the sternum. These ribs are located at the lower part of the rib cage. A stab wound between these ribs on the left side may be less likely to damage critical organs because the left side contains the spleen, which is protected by the ribs above it. However, even in this region, a stab wound could potentially puncture the kidney or damage other structures.

Side of the Body: Left vs. Right

The left side of the body contains the heart and the spleen, while the right side contains the liver and gallbladder. Therefore, a stab wound on the right side between ribs 11 and 12 might be considered to cause less immediate damage compared to the left side.

Real-Life Incident: A Fatal Stab Wound

Consider the case of a friend who was murdered. The perpetrator stabbed him five inches deep into his back between his ribcage and hipbone and he died from loss of blood. Despite the depth of the wound, the knife did not hit any organ. The perpetrator had done extensive research on stab wounds, which is why he was convicted of first-degree murder.

Factors Influencing the Severity of Stab Wounds

Unless you possess super strength, reaching the 2nd and 3rd ribs directly to the right of the sternum in an adult male over 6 feet tall can be challenging. Even getting through clothing is more difficult than one might imagine. Here are some additional insights into the factors that influence the severity of a stab wound:

Lower Ribs: Less Vital Protection

While some suggest that lower ribs are less protective of vital structures, the upper ribs provide a strong barrier, especially in the front and back. In real-life gore videos, such as a woman stabbed in the neck 40 times with a folding knife, the first 39 stabs did not kill her. Similarly, a girl taking a machete to the gut still survived. A man stabbed an offender who had a gun, and the gun wielder dropped the gun and continued to fight.

Knife Design and Human Anatomy

Knives without significant mass (over a quarter pound) lack the required momentum to penetrate the cartilage over the ribs. For the best chances, knives need to be very sharp, thin, long, and heavy. Smaller individuals are easier to penetrate but move out of the way faster. Very strong, well-trained individuals can acquire the strength to penetrate a rib with a vertical stab, but most first-timers will fail.

Common Cutting Surfaces vs. Ribs

Making a cut down the arm from the elbow to the wrist is much easier and opens up the entire arm, potentially leading to fatal blood loss within a minute. In contrast, penetrating the ribcage requires both force and the correct angular orientation, making it a more significant challenge.

Conclusion

A stab wound between ribs 11 and 12 on the right side of the body might cause the least amount of damage, but it could still be very serious. Any stabbing injury requires immediate medical attention, regardless of the location.
