Amputation of the Hand or Finger and Prosthetics

For a computer engineer like Saku, typing is a critical part of every day. Before receiving two PIPDriver™ prostheses, his speed and accuracy suffered; with them on, however, Saku can move across the keyboard with ease again. The articulation of the devices facilitate fine motor function, making this engineer’s workday that much smoother.

I became familiar with Naked Prosthetics after a woodworking accident. I have one of their unique prosthesis fitted for the partial loss of a finger and have ordered another for my missing index finger. The prosthetics were easy to fit and are easy to wear and use, while giving give an incredible amount of support to the entire hand. I have met with the personnel in Tumwater on two occasions and have found all of them to be very professional, most considerate and helpful, and dedicated to providing the best fitting and functional prosthetic which met my needs.

As a benchmark to facilitate future model modifications, the circumferencereductions that were made on the finger models for this series of patientscan be categorized into three ranges: small (1-3 percent), moderate (5-7percent), and large (8-9 percent). Feedback received from patients aboutloose prosthetic fit during our initial experience with fitting thimbleprosthesis had prompted us to experiment on a larger circumference reductionwhen modifying the finger models. The results of this retrospective studydemonstrated that a larger model circumference reduction of between fivepercent to eight percent is necessary for achieving a secure prosthetic fitand for obviating a subsequent need for rectifying the prosthesis. Thecomplaints in two patients--one with an eight percent and the other with anine percent model circumference reduction--of an uncomfortably tight fitsuggested that eight percent might be the threshold reduction beyond which anexcessively tight fit may result.

"We believe this is the first time a person using a has immediately performed individual digit movements without extensive training," study senior author Dr. Nathan Crone, a professor of neurology at the Johns Hopkins University School of Medicine, . "This technology goes beyond available prostheses, in which the artificial digits, or fingers, moved as a single unit to make a grabbing motion, like one used to grip a tennis ball." []

The new hand after amputation
Modern orthopaedic technology makes it possible to fit the affected hand with a hand, partial hand or finger prosthesis after an amputation. The aim of the prosthesis is to enable the affected person to do things that would not be possible without a prosthesis.

Prosthesis for the amputated ring finger

Exacting prior circumference reduction of finger models for producingthimble-type prostheses for distal finger amputations is crucial toachieving good prosthetic fit, given the shorter distal segment of theresiduum available for anchorage and the problems of residuum shrinkage fromdonning the prosthesis or late tissue atrophy. A five to seven percentcircumference reduction in the finger models against the respective models ofthe residuum was shown to best translate into good prosthetic fit of thesesuction-fitted thimble prostheses.

The adequacy/amount of the soft tissue cover in the residuum may also beconsidered when contemplating between a moderate and a large circumferencereduction. Of the three patients who had either a one percent or two percentmodel circumference reduction and yet had no problems with a poor fit, two hadfinger residua that were assessed as having inadequate/poor soft tissue cover(i.e., bony). None of the three patients who had bony residua and had amoderate to large model circumference reduction had a loose prosthetic fit. Although not proven statistically (p=0.14, logistic regression), thisseems to suggest that for bony residua, a moderate model circumferencereduction would suffice in achieving a good prosthetic fit, while residuahaving good soft tissue cover and therefore more susceptible to volumetricreduction from tissue compression may require a more aggressive modelcircumference reduction.
