I am contemplating undergoing shoulder extension to enhance my wingspan so that it roughly aligns with my height after limb lengthening (LL) (i need a 2 inches increase but wish to avoid arm lengthening due to associated risks). I have delved into the subject and discovered that it has the potential to widen shoulders by up to 1 inch at most. It doesn’t sound too terrible, but is it indeed impossible to broaden them more than just one inch?
