Calculation of angles in normal anatomical curved bones that are fractured.

In summary, the conversation discusses the challenge of calculating the angle/curve or changed angle/curve of a fractured bone that has healed or been fixed in a none anatomical position. It is suggested that the angle is determined by 2 lines that identify the direction of the bone at either end, and finding these lines for the bone with and without fracture can help determine the change in angle.

Hi,
I am an orthopedic surgeon. Many of our long bones are anatomically curved. When they fracture they sometimes heal in a none perfect/anatomic position.

How do one calculate the angle/curve or changed angle/curve of a fractured bone healed or fixed none anatomically

Please see my drawn illutration

Hi thormunch! Welcome to MHB!

The angle a bone makes is determined by 2 lines that identify the direction of the bone at either end.
If you find these lines for the bone with and without fracture, you can find the change in angle.

So I assume your challenge is how to find such lines?
 

FAQ: Calculation of angles in normal anatomical curved bones that are fractured.

How do you calculate the angle of a normal anatomical curved bone?

The angle of a normal anatomical curved bone can be calculated using a protractor or goniometer. The instrument is placed on the bone, and the angle is measured by aligning the arms of the protractor or goniometer with the bone's curved surface.

What are the factors that affect the calculation of angles in fractured bones?

The factors that can affect the calculation of angles in fractured bones include the severity and type of fracture, the presence of any displacement or rotation, and the location of the fracture within the curved bone.

How are angles calculated in fractured bones with multiple fragments?

When a fractured bone has multiple fragments, the angle is calculated by measuring the angle between the two main fragments that form the fracture line. In some cases, additional measurements of smaller fragments may be necessary to accurately determine the angle.

Can the angle of a fractured bone change over time?

Yes, the angle of a fractured bone can change over time due to the natural healing process. As the bone heals and remodels, the angle may shift slightly. It is important to monitor the angle over time to ensure proper healing.

How does the calculation of angles in normal anatomical curved bones differ from that of straight bones?

The calculation of angles in normal anatomical curved bones is more complex compared to straight bones. This is because curved bones have multiple points of reference and may have varying degrees of curvature. Additionally, the presence of a fracture can further complicate the calculation process.
