Spinal fractures take different lengths of time to heal, depending on the type of fracture that occurs. According to Medline Plus, most spinal compression fractures that occur from an injury heal in about eight to 10 weeks. In some cases, these injuries heal with nothing but rest, the use of a back brace and pain medications. However, surgery is required to heal badly damaged vertebrae.Know More
Humans have 33 different vertebrae. Scientists and doctors group the vertebrae into different sections. The neck is comprised of seven cervical vertebrae, while the upper back contains 12 thoracic vertebrae. Five lumbar vertebrae support the lower back. The sacrum has five fused vertebra, and the coccyx has four fused vertebrae. According to the Mayfield Clinic, 64 percent of all broken vertebrae occur in the lumbar region.
The human vertebrae are comprised of three primary components. The vertebral body forms the posterior side of the bone and supplies the bulk of the vertebrae’s mass. The vertebral body is the weight bearing part of the bone, and each vertebra is separated from the adjacent vertebrae by structures called discs. The spinal cord passes through the middle portion of the vertebrae, called the spinal canal. The surrounding bone helps to protect the vulnerable cord from injury. The remaining portion of the vertebrae forms the vertebral process, which provides attachment points for muscles and ligaments.Learn more about Bones
To break the neck of a human, 1,000 to 1,250 foot-pounds of torque is considered sufficient. When hanging someone, a typical drop of 5 to 9 feet is enough to generate the force required to break the neck when the person hits the end of the rope.Full Answer >
A femur, which is the largest bone in the leg and the body as a whole, can be fractured with approximately 4000 newtons of energy, according to an article in SciFighting. The tibia and fibula, both smaller bones, require significantly less force.Full Answer >
If pressure is applied across the weakest point of a small bone, it takes about 25 pounds of pressure to cause a fracture. The force it takes to break a human bone is contingent on which bone it is.Full Answer >
The amount of force required to break a human bone varies depending on which bone and its density. On average, the human femur requires 1,700 pounds per square inch to be cleanly broken, while a weaker bone, such as the clavicle, takes considerably less force to break.Full Answer >
