Abstract
In one embodiment, an ambulatory traction device includes a first support configured to be positioned on a user's body and a second support configured to be positioned on the user's body spaced apart from the first support such that a portion of the user's body is positioned between the first and second supports. The traction device also includes one or more lifting mechanisms that each couple the supports and apply a decompressive force to the portion of the user's body when the supports are positioned on the user's body. Each lifting mechanism includes a sleeve having a non-circular cross-section and operable to contain a fluid. Each lifting mechanism also includes a piston configured to move within the sleeve in response to an increase in pressure within the sleeve.
