Southern Bone & Joint Study - Brimless Sockets

Biomechanical Superiority of Brimless Versus Ischial Ramus Containment (IRC) Sub Atmospheric Transfemoral Interfaces

The investigators are comparing a new type of prosthetic socket for above knee amputees to the standard of care. The hypothesis is that the new type of socket will show equivalence to the standard of care using our designated outcome measures.

Inclusion Criteria:

• Unilateral transfemoral or knee-disarticulation amputee
• 18 to 85 years of age
• K3 (variable cadence and community) ambulators;
• Be able to independently provide informed consent
• Be willing to comply with study procedures.

Exclusion Criteria:

• History of chronic skin breakdown on the residual limb
• Conditions that would prevent participation and pose increased risk (e.g. unstable cardiovascular conditions that preclude physical activity such as walking)
• Use of any assistive devices/walking aids, beyond a prosthesis, to ambulate
• Unwillingness/inability to follow instructions
