Anton G. Johannesson, PhD, CPO, Össur Clinics, writes that unique human qualities mean that there cannot be a standard for “optimal” prosthetic interface output. He goes on to address the historical background and evolution of prosthetic interface management, and asks, “Which shape should be captured?”
Johannesson argues that while shape capture, along with additive manufacturing, artificial intelligence, and other technology applications will continue to improve manufacturing precision, only O&P practitioners can address the individual patient complexities that influence interface performance.
“Residual limb tissues, suspension systems, gait mechanics, skin adaptation, and individual user characteristics interact dynamically throughout prosthetic use, limiting the ability of shape capture and manufacturing processes alone to determine successful outcomes,” he writes.
