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

Click For Summary
SUMMARY

The discussion focuses on calculating the angle of anatomically curved long bones that have fractured and healed in a non-anatomic position. An orthopedic surgeon seeks methods to determine the changed angle of these bones post-fracture. The key approach involves identifying two lines that represent the direction of the bone at both ends to calculate the angle difference between the fractured and unfractured states. This method provides a systematic way to assess the degree of misalignment in healed fractures.

PREREQUISITES
  • Understanding of anatomical bone structure and curvature
  • Knowledge of basic geometry for angle calculation
  • Familiarity with orthopedic terminology related to fractures
  • Experience with imaging techniques to visualize bone alignment
NEXT STEPS
  • Research methods for measuring angles in orthopedic imaging
  • Explore software tools for 3D bone modeling and analysis
  • Learn about the principles of fracture healing and anatomical alignment
  • Investigate case studies on non-anatomic healing of long bones
USEFUL FOR

Orthopedic surgeons, medical students specializing in orthopedics, radiologists, and professionals involved in fracture management and rehabilitation.

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?
