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

AI Thread Summary
The discussion focuses on the challenges orthopedic surgeons face when calculating the angles of anatomically curved long bones that have fractured and healed improperly. It emphasizes the need to establish two lines that define the bone's direction at either end to determine the angle change. Participants discuss methods for identifying these lines to accurately assess the altered angles post-fracture. The conversation highlights the importance of precise calculations for effective treatment planning. Accurate angle measurement is crucial for ensuring proper healing and alignment in fractured bones.

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?
 
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
