AMPUTATION-PROSTHETIC SUSPENSION & LINER

SUMMARY

STRAP SUSPENSION
1. Suprapatellar suspension strap.

BRIM SUSPENSION
2. Supracondylar brim suspension/supracondylar wedge (PTB-SC): PTB socket with medial and lateral walls extending above the femoral condyles for suspension. Instead of removable medial brim or wedge, a compressible foam wedge build-up may be incorporated into the soft liner.

3. Supracondylar-suprapatellar brim suspension (Patella Tendon Bearing Kegel, PTK): Similar to the PTB-SC socket with the addition of suprapatellar trim lines which improve suspension, designed for short stumps, difficult to sit on.

SLEEVE SUSPENSION
4. Sleeves made of neoprene, rubber, latex or silicone (e.g. Icelandic Roll-On Silicone Suspension [ICEROSS] with pin lock or Velcro strap) may be used as a primary suspension system or in combination with other mechanisms.

PIN & VACUUM SUSPENSION
5. Pin suspension: design includes a silicone or other gel insert/liner with an attached distal pin that locks into the bottom of the plastic laminated socket.

6. Vacuum suspension: design includes a silicone or other gel insert or liner with the use of a one-way expulsion valve in the distal aspect of the socket.

THIGH LACERS
7. Thigh lacers: Connects a leather thigh (femoral) corset to a PTB prosthesis through metal joints and side bars, not used frequently these days.
