Breaking legs to look taller may sound unbelievable, but there is a procedure called limb-lengthening surgery that gradually lengthens an arm or leg. The idea displayed in Dakota Johnson's lead romcom movie, Materialists, is no longer merely theatrical magic but is gaining popularity worldwide.

What Is Limb-Lengthening Surgery?

Limb-lengthening surgery is a procedure where the bones and soft tissues, like the skin, muscles and nerves, etc, in your arms and legs slowly increase in length. According to experts, the limb lengthening procedure can also be combined with gradual or acute deformity correction.

To increase height through limb-lengthening surgery, doctors typically perform surgery on the humerus (upper arm bone), radius/ulna (forearm bones), femur (thigh bone) and tibia (shin bone).

Benefits Of Limb-Lengthening Surgery

The Cleveland Clinic suggests that limb-lengthening surgery can be life-changing for individuals who have bone discrepancies or bone growth conditions. It states, "Newer internal devices can make your limb lengthening process easier and safer than ever before." This procedure has a high success rate with many people living full and active lives in their lengthened arm or leg.

Briggs warns that patients face months of treatment, which can be "extremely painful", with the possibility of infection, nerve damage, blood clots and even permanent disability.

"Anyone considering this surgery for cosmetic reasons abroad should think very carefully about the long recovery and the risks, and I would urge against it unless well informed about where they are seeking treatment," he said.
