The FSLF is used in prosthetic and orthotic clinics, limb-fitting centres, anaplastology practices and rehabilitation services that restore the appearance of the lower limb. Its users are people with a below-knee prosthesis who want it to look like a natural leg and foot, and people with congenital or acquired differences of the lower leg and foot.
Patient experience is why services offer it. Many lower-limb prosthesis users dress to hide the prosthesis, choosing trousers and closed shoes for years. Occasions bring that choice into focus: a wedding, a graduation, a holiday, a family photograph. A single silicone piece that restores the shin, the ankle and the foot with its toes gives a continuous, natural outline, and with it the option of a dress or a bare-legged outfit.
The clinician records the dimensions of the leg and foot to be restored, usually with the other leg as reference, and Wonderful produces the FSLF to that record. At the fitting, the piece is checked along its whole length: the contour of the calf, the line of the ankle, the shape and position of the toes and how the foot sits in the wearer's chosen footwear. Because it is one piece, the outline is judged as a whole.
Typical uses include finishing a below-knee prosthesis for a wearer who wants a natural leg and foot, preparing for a particular occasion, and replacing a worn piece from the same record. Prosthetists, technicians and anaplastologists handle the order and the fitting. In each case, the FSLF gives the wearer one continuous leg and foot, made to their own dimensions.
