Partial hand prosthesis
Cosmetic, functional and electronic hand/finger prostheses planned on the basis of the preserved hand structure for losses at the finger and hand level.
What is a partial hand prosthesis?
A partial hand prosthesis is an upper limb prosthesis used when one or more fingers, the palm (metacarpal region) or part of the hand is missing. Since part of the hand and the wrist are preserved at this level, the prosthesis is planned to complement the function of this preserved structure and to support the ability to hold and grasp.
Partial hand losses can vary widely, ranging from a single fingertip to losses involving several fingers and most of the hand. For this reason, the solution is determined individually according to the exact location of the loss and the person's daily needs.
Partial hand level and preserved function
At the partial hand level, the aim is to help regain grasping function by supporting the preserved wrist, palm and any remaining fingers. The more structure is preserved, the more targeted the support provided by the prosthesis can be.
At this level, the prosthesis is designed not as a sum of individual parts but as a whole that works in harmony with the preserved hand structure. Being able to perform two-handed tasks again, with the support of the opposite hand, is one of the main goals considered in planning.
Components of a partial hand prosthesis
The components are planned as a whole according to the location of the loss; selection and adjustment are carried out under the guidance of the physician and clinical team.
Partial hand socket
The part that fits the preserved hand and wrist structure individually, carries the prosthesis and determines comfort.
Finger / terminal components
Terminal parts that replace the missing fingers; they can be passive, body-powered or electronic.
Grasping surface
A structure that supports holding by creating a counterforce together with the preserved fingers or the palm.
Control and type options
There are different approaches at the partial hand level. Which one is suitable is determined by the specialist team according to the location of the loss, the preserved function and the person's goals.
Passive and cosmetic
Finger/hand solutions without a motor that prioritize a natural appearance and basic supporting function.
Learn moreFunctional (body-powered)
Mechanical solutions that work through movement of the preserved hand and wrist to make grasping easier in certain tasks.
Electronic (myoelectric)
An approach, considered in suitable cases, in which finger movements are controlled by sensors that detect muscle signals.
Learn moreThe fitting process
Physician's Prescription / Medical Report
Fitting begins with a specialist physician's prescription/medical report.
Assessment and Measurement
The location of the loss, the preserved function and skin condition are assessed; individual measurements are taken.
Fitting Trial and Adjustment
The socket and terminal components are planned; fit and comfort are adjusted during the fitting trial stage.
Training and Follow-up
Use training is provided; follow-up is carried out for check-ups and, when needed, modifications.
Frequently asked questions
Is a partial hand prosthesis the same as a finger prosthesis?
A finger prosthesis is a subtype of the partial hand level. Partial hand prosthesis is a general heading that covers different levels of loss, from a single finger to most of the hand.
Is electronic control possible with a partial hand prosthesis?
In some cases, electronic finger solutions operated by muscle signals may be considered. Suitability is determined clinically according to the preserved function, muscle signals and the location of the loss.
Which type is suitable for me?
The suitable approach depends on the location of the loss, the preserved hand structure, skin condition and daily needs, and is determined only by the assessment of the physician and the clinical team.
