The Victoria Hand

Features of the Victoria Hand

Rotatable Thumb

The thumb can be rotated (adduct/abduct) by the user, to achieve different positions allowing for many different grasps. This includes a one-finger pinch, a two-finger pinch, a power grasp, or a lateral grasp.

Backlock Mechanism

The voluntary close (VC) model contains the back-lock mechanism. This lets the user lock the hand closed, for tasks such as carrying bags, or constant grip onto objects.  

Rotatable Wrist

The wrist contains a ball-and-socket mechanism that allows the user to quickly and easily change the orientation of the hand. This wrist can rotate the hand up to 360 degrees, while simultaneously being flexed or extended by 25 degrees.

Adaptive Grasp

The Adaptive Grasp mechanism allows the fingers to conform around the shape of oddly shaped objects making them easier to grasp and hold.


The Limbforge arm is passive, meaning it is not able to open and close, but is designed to be aesthetically pleasing and very closely match the appearance of a natural arm. LimbForge minimizes the appearance of limb difference, opening the door for more social integration.


We are committed to helping as many amputees as possible despite wide ranging variations in amputations.  The Victoria Hand Project currently offers three different arm prostheses.


The original Victoria Hand was designed for individuals with amputations below the elbow. The prosthesis consists of a hand, wrist, socket, triceps brace, and harness. We have provided over fifty of these prostheses and model the rest of our prosthetic designs on the trans-radial prosthesis.

The trans-radial suspension prosthesis is designed for amputees with shorter remnant limbs that are closer to the elbow. Our regular Victoria Hand was not suitable for this so we created a two part socket that can accommodate the shorter limb. This socket extends further up the arm for better control while maintaining a natural appearance.


The trans-humeral socket is the newest socket offered by VHP. The trans-humeral socket is for individuals with amputations between the shoulder and the elbow. It contains a ball-and-socket elbow which allows amputees to adjust the arm and lock it in place.
