Abstract: The present invention is a new method for combining five fundamental methods of orthopedic immobilization into one multipurpose utility, integrated synergistic emergency spline (30) that operates using various integrated synergistic combinations of rigid fixation, soft fixation, inflation-actuated fixation, vacuum-actuated fixation, and traction-actuated fixation methods for strengthening and providing backup immobilization of each single method. Splint (30) is of layered design and function, comprised of an anatomically shaped unibody envelope (32) with a medial long axis monostay pocket (102) for retaining a removable central stiffening monostay (100), and a plurality of self-stowing, orbital compression, isokinetic tensing straps (34a-l) for circumferential closure. Contained within unibody envelope (32) is a stiffening framesheet (94) which provides shape, a malleable support platform, and energy transfer base for detachable traction system (71).
