Scientists who were running a routine DNA test on this mummy found something astonishing. Evidence of surgery that was performed over 3,000 years ago.

A 23cm orthopaedic screw was found embedded in the knee joint. This male mummy is thought to have died sometime around the 11th century BC.

The pin is made with some of the same designs that modern surgeons use to get good rotation on the bone. Extremely innovative for the time period.

The screw is held in place by organic resin - very similar to what surgeons use today.

No other example of such ancient surgery has been found in any other mummy. Is this an isolated case? Or are there other mummies out there with similar screws in their bones?
