A new cause of erectile dysfunction (ED) in amputees is identified: compression from above-knee prosthetics. This prosthetic pressure can cause site-specific penile artery and veno-occlusive dysfunction, impacting sexual health.

Area of Science:

  • Urology
  • Prosthetics Engineering
  • Vascular Surgery

Background:

  • Blunt pelvic and perineal trauma can cause erectile dysfunction (ED) through localized vascular injury.
  • Previous cases linked ED to direct trauma, but not prosthetic device pressure.

Observation:

  • A young, previously potent amputee presented with erectile dysfunction.
  • The patient used a weight-bearing, lower extremity, above-knee prosthetic device.

Findings:

  • The erectile dysfunction was linked to a novel form of blunt trauma: site-specific compression from the prosthetic device.
  • Clinical evaluation revealed corporal veno-occlusive dysfunction and common penile arterial occlusive pathology.
  • These vascular issues occurred in the perineal area where the prosthesis contacted the body, suggesting a crush-like injury mechanism.

Implications:

  • Above-knee prosthetic design may need modification to prevent penile vascular compromise and subsequent erectile dysfunction.
  • This finding highlights a previously unrecognized cause of ED in amputee populations.
  • Further research into prosthetic-device-induced vascular injury is warranted.
