How to measure Cobb angle on Xray Films using your iPhone
Step 1: Identify and mark the end vertebrae
Step 2: Open Measure App on Iphone. https://apps.apple.com/us/app/measure/id1383426740
Step 3: There are two options on the bottom screen. “Measure” and “Level”. Choose “Level”. This brings up the inclinometer.
Step 4: Place the iPhone’s edge along the line drawn on the lower end vertebra.
Step 5: Touch the iPhone’s screen somewhere in the middle. The degrees recalibrate to Zero.
Step 6: Now move the iPhone’s edge to the line drawn for the upper-end vertebra.
Step 7: The reading on the iPhone will give you the Cobb angle.
Selecting posterior fusion levels in AIS
I gave this talk at the POSICON 2019 in Mumbai as a part of the instructional course on Adolescent idiopathic scoliosis. I discuss the Lenke classification and how it helps decide fusion levels. The video also includes the concept of last touched vertebra and how it helps to decide the LIV.
