From the Guidelines
A femoral spiral fracture can occur from a fall onto the buttocks, although it is less common than other mechanisms, and the likelihood of such an injury should be considered in the context of the fall's specifics and the individual's overall health. When considering the possibility of a femoral spiral fracture from a fall onto the buttocks, it's essential to understand the mechanics of how such fractures occur. According to the study by 1, spiral fractures are caused by torsion or twisting of a long bone along its long axis. While the study primarily discusses fractures in the context of child abuse, the principles of fracture mechanics apply broadly.
In the context of a fall onto the buttocks, if the leg is twisted or bent in such a way that it applies a torsional force to the femur, a spiral fracture could potentially occur. This is more likely in scenarios where the fall is from a height, or there is an unusual twisting motion involved. However, the exact mechanism and likelihood can vary greatly depending on the specifics of the fall and the individual's bone health, among other factors.
Symptoms of a femoral spiral fracture include severe pain, inability to bear weight, visible deformity, swelling, and bruising around the thigh. Treatment typically involves surgical fixation with intramedullary nails or plates and screws, followed by physical therapy, as discussed in the context of hip fractures by 1. The healing process generally takes several months, with initial weight-bearing restrictions and a gradual return to activities as healing progresses.
It's also important to consider the broader context of extremity fractures, as discussed by 1, which can be life or limb-threatening, especially when involving long bones or major blood vessels. Therefore, any suspicion of a femoral spiral fracture should be taken seriously and promptly evaluated by a healthcare professional to ensure appropriate treatment and minimize potential complications.
Given the potential for significant morbidity and mortality associated with femoral fractures, particularly in elderly individuals or those with compromised bone health, prompt medical evaluation and treatment are crucial in the event of a suspected femoral spiral fracture from any cause, including a fall onto the buttocks.
From the Research
Femoral Spiral Fractures
- Femoral spiral fractures are a type of fracture that can occur in the femur, which is the largest and strongest bone in the human body 2.
- These fractures can be caused by various types of trauma, including motor vehicle accidents, falls, and abuse 2.
Causes of Femoral Spiral Fractures
- In adults, the most common cause of femur fracture is motor vehicle accidents 2.
- In children, abuse is often the cause of femur fractures 2.
- In the elderly, femur fractures most often occur from falling 2.
- However, there is no direct evidence to suggest that a femoral spiral fracture can occur from a fall onto the buttocks.
Treatment of Femoral Spiral Fractures
- Femoral spiral fractures can be treated with various methods, including intramedullary nailing 3, 4, 5.
- The use of reamed locked intramedullary nails can provide appropriate stability for femoral spiral fractures 3.
- The combination of proximal femoral locking plate and proximal intramedullary nail can also be used to treat femoral subtrochanteric spiral fractures 4.
Complications of Femoral Spiral Fractures
- Femoral spiral fractures can be complicated by various factors, including instability and difficulty in achieving good contact between the nail and femoral endosteum 3.
- The use of certain implants, such as the unreamed AO femoral intramedullary nail with spiral blade, can also be associated with complications, including bending, migration, and breakage of the spiral blade 5.
