The Krukenberg procedure separates the bony remnants of the forearm into a makeshift pincer. The procedure involves separating the ulna and radius for below-elbow amputations, and in cases of congenital absence of the hand, to provide a pincerlike grasp that is motored by the pronator teres muscle.
While researching 3D printing, Lockey's mother discovered Open Bionics, who were looking for a below-the-elbow amputee to trial new prosthetic arms. [3] Since being chosen in 2016, Lockey has used bionic arms developed by the company, [4] which enable her to perform actions such as picking up small objects and playing video games.
Amputation is the removal of a limb by trauma, medical illness, or surgery. As a surgical measure, it is used to control pain or a disease process in the affected limb, such as malignancy or gangrene. In some cases, it is carried out on individuals as a preventive surgery for such problems.
Hugh Herr climbs the wall at the MIT Media Lab's h2.0 symposium on May 9, 2007, watched by fellow bilateral amputee Aimee Mullins. While a postdoctoral fellow at MIT in biomedical devices, Herr began working on advanced leg prostheses and orthoses, devices that emulate the functionality of the human leg. [1]

In 2015, Disney and Open Bionics announced a partnership to create superhero-themed prosthetics for young amputees. [8] In the same year, the company won the 2015 James Dyson Award in the UK for innovative engineering [9] [10] and Tech4Good's 2015 Accessibility Award. [11] [12] In 2016, it won a Bloomberg Business Innovators award. [13] [14]
A Jaipur foot in production. The Jaipur foot, also known as the Jaipur leg, is a rubber-based prosthetic leg for people with below-knee amputations.Although inferior in many ways to the composite carbon fibre variants, its variable applicability and cost efficiency make it an acceptable choice for prosthesis.
Rotationplasty allows the use of the knee joint, whereas amputation would result in loss of that joint. Therefore, it provides a better attachment point and range of motion for a prosthetic limb. As a result, children who have had rotationplasty can play sports, run, climb, and do more than would be possible with a jointless prosthetic.
