Prosthesis use significantly improves hand function and grip strength in patients with multiple finger amputations. This functional benefit extends to daily activities, enhancing overall quality of life.

Area of Science:

  • Orthopedics
  • Rehabilitation Medicine
  • Prosthetics

Background:

  • Traumatic amputation of multiple fingers results in significant functional and psychological deficits.
  • Previous research on finger prostheses primarily focused on psychological benefits, overlooking functional outcomes.

Purpose of the Study:

  • To evaluate the functional improvement in hand function tests for patients with multiple digit amputations using a prosthesis.
  • To determine if multiple finger prostheses provide a consistent functional benefit, given their expense.

Main Methods:

  • Ten patients with multiple finger amputations underwent a battery of hand function tests.
  • Patients rated their ability in activities of daily living with and without their prosthesis using the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire.

Main Results:

  • Significant improvements were observed in 3-finger-pinch and grip strength.
  • A trend of improvement was noted in tip-pinch, lateral-pinch, and grip strength across various dynamometer positions.
  • Prosthesis use globally improved function in activities of daily living, with notable gains in tasks like opening jars and writing.

Conclusions:

  • Prosthesis use offers a tangible functional benefit for patients with multiple finger amputations.
  • The study demonstrates that finger prostheses enhance performance in various daily activities, supporting their clinical utility.
