This gruesome procedure has existed for some time now, but the patients were mainly dwarves and children with one leg longer than the other. Now, a lot more guys are shelling out serious dough for this surgery that adds height by lenghtening the patient's legs.

Dudes who are unhappy with their natural height have doctors break their shin bones in half and insert a telescopic rod between the two halves. The rod slowly pulls the bone apart very slowly, approximately one millimeter a day. The slow lengthening allows the bone, muscle tissue, ligaments, and skin to regenerate around the ever-elongating limbs. 

The entire process takes anywhere between three months and two years, and is reportedly excruciatingly painful. Besides, there are measures you can take to at least appear taller without having your legs cracked in half with a bonesaw.
