momentum Since its introduction in the late 1990s, there has been a significant increase in the clinical application of sub-atmospheric (elevated vacuum) prosthetic suspension. By Miki Fairley Sub-Atmospheric Socket Technology Gains “ When I began teaching…sub-atmospheric technology around ten years ago, only about 1 percent of the clinicians were using it; now I’d say the percentage is about 30–40 percent,” says Stan Patter-son, CP, president of Prosthetic & Orthotic Associ-ates, Orlando, Florida. “More and more practitioners are realizing its great potential for their patients.” Pioneered by Carl Caspers, CPO, a transtibial amputee, sub-atmospheric socket technology was ini-tially developed for the transtibial amputation level. However, clinicians soon saw its applicability for other amputation levels as well and are successfully using it for transfemoral, partial foot, hip disarticula-tion, hemipelvectomy/transpelvectomy, and transra-dial prostheses. Enthusiasts of the technology now have their own information-sharing and networking group, the Sub-Atmospheric Technology Group (SATG), under the auspices of the Lower Limb Prosthetics Society of the American Academy of Orthotists and Prosthe-tists (the Academy) and chaired by Michael Leach, CPO, clinical specialist, prosthetics, Professional and Clinical Services, Ottobock Manufacturing, Salt Lake City, Utah.
