The Signature Series APOPPS® (Adjustable Post-Operative Preparatory Prosthetic System) is designed to enhance post-operative, transtibial limb rehabilitation. FLO-TECH® O&P Systems, Inc.'s new Signature Series will replace our current 7 socket sizes with just 4 sizes; both 7" and 9" lengths, left and right, with: #1416 [MPT 14"-16"], #1618 [MPT 16"-18"], #1821 [MPT 18"-21"], and #2124 [MPT 21"-24"] for your transtibial patients. We've combined our sizing in order to provide a larger range and sustained use of the sockets for anatomical shaping of your patients. Our new sockets now give you more versatility for edema control, knee flection contracture management and aid against distal end breakdown! The new Series will save money by decreasing your inventory to only 4 sizes of each FLO-TECH-TOR , UFOS and VCSPS (custom sockets are still available). Each socket has the same patented design & quality synonymous with the FLO-TECH® name.
