In recent years, advances in 3D-printed upper-limb prostheses have captured much media attention and popular imagination. But use of the 3D process in fabricating lower-limb prosthetic components, particularly those beyond prototypes and test sockets, has grown at a slower rate, as clinicians and technicians consider factors such as strength and durability, efficiency versus traditional methods, and reimbursement implications. The O&P EDGE spoke with experts in the profession who shared their perspectives on these issues and discussed how 3D printing is earning an important place in the lower-limb prosthetics arena.
Part of the problem, many agree, is the lack of a consensus regarding what constitutes a “definitive” or final 3D-printed lower-limb prosthetic socket. What features are required—and what degree of strength and what level of durability must they demonstrate to qualify? Some sources pointed out that no standards exist for lower-limb sockets fabricated in the traditional manner, yet their right to the title definitive has not been questioned.
