The Ischial Containment (IC) Socket is the most commonly prescribed modern transfemoral socket. It encloses the ischial tuberosity and part of the pelvis, providing excellent stability and control.

Benefits

  • Excellent mediolateral stability
  • Improved gait symmetry
  • Better comfort
  • Enhanced prosthetic control
  • Suitable for active users

Recommended For

  • Most transfemoral amputees
  • Medium to high activity levels
  • Long-term prosthesis users
