A convertible crutch is disclosed having a generally L-shaped upper support section to a generally S-shaped central support section connected, in turn, to a substantially straight lower support portion. The connection mechanism between the upper support section and the central support section can be utilized to connect the upper support section to the lower support section and convert the crutch to a cane when the central support section is removed.
