Abstract: A lumbosacral back support system with interchangeable and positionally adjustable lumbosacral orthopedic support members for supporting the spine of a user during physical activity, specifically for athletes and industrial workers. A back support band is provided with a first releasable attachment mechanism. A lumbosacral support member with second releasable attachment mechanism is provided for engagement with the first releasable attachment mechanism. The first and second releasable attachment mechanisms are arranged for attaching a lumbosacral support member to the back support band at a variety of positions relative to the spine of the user. The releasable attachment mechanism of the present invention provides the user the option to substitute different lumbosacral support members on the back support band. Additionally, the back support band may be releasably attach to a compression-type short to further secure the lumbosacral back support system to the user.

Abstract: A lumbosacral back support member is releasably secured to the user by a stabilizing belt generally worn over the user's clothes. The stabilizing belt may be inserted into the belt loops on the user's pants, attached to the belt loops, or engaged with the narrow portion of the user's waist. The lumbosacral support member is releasable attached to the stabilizing belt. The user positions the lumbosacral support member around the spine from approximately the sacrum to at least the L3 lumbar vertebra.
