A twist-drivable pin assembly includes first and second drivers, each having a driving end which can be received in a bore in the end of a twist-drivable pin, and an opposite end at which torque can be applied. The cross-sectional shape of each of the drivers at its driving end has a first plurality of apexes whose relative locations coincide with the apexes of a regular polygon such as a hexagon. The drivers differ from one another in their cross-sectional shapes at the driving end by virtue of one or more faces of at least one of the drivers between adjacent pairs of apexes having a groove formed in it. Each of first and second twist-drivable pins has a bore extending into it which is defined by a second plurality of apexes arranged as a regular polygon such as a hexagon and which is open at one end.

Assistive movement devices and methods therefor are provided that are capable of redirecting loads from an individual's foot to hip when an individual is recovering from an injury at or below the knee. The devices include a frame assembly comprising an upper member, a lower member, and a joint therebetween. An upper attachment is secured to the upper member and is configured to be secured to the thigh of the individual's leg, and a lower attachment is secured to the lower member or the base and is configured to be secured to a portion of the leg below a knee thereof. A base is secured to the lower member and is configured to support a foot of the leg, and the device adjustably redirects at least a portion of a load resulting from the individual standing and walking from the base to the upper attachment.
