Controlled tissue expansion for correcting amputation stump scar.

G Rubin1, L J Lachman, A Scheinhaus

  • 1Veterans Administration, New York City.

Orthopaedic Review

Summary

Tissue expansion is a new technique to fix amputation scars that hinder prosthesis use. This method creates excess skin for scar removal and improved prosthetic fitting.

Area of Science:

  • Plastic Surgery
  • Biomaterials Science

Background:

  • Amputation scars can cause significant functional impairment, particularly when they interfere with the proper use of prosthetic devices.
  • Scar tissue at amputation sites often lacks the elasticity and volume required for comfortable and effective prosthesis integration.

Observation:

  • A novel tissue expansion technique utilizing a progressively distended silicone bag has been developed.
  • This method is specifically designed to address problematic amputation scars that impede prosthetic functionality.

Findings:

  • The silicone bag is placed subdermally, gradually stretching the surrounding skin over time.
  • This controlled expansion generates sufficient cutaneous laxity to facilitate surgical revision.

Implications:

  • Successful application of this technique allows for the plastic closure and elimination of problematic scar tissue.
  • This can lead to improved comfort, function, and integration of prosthetic devices for amputees.
