Abstract: A suspension liner has a liner body portion, a textile material, and a plurality of seals formed along a length of the suspension liner toward a closed distal end and protruding circumferentially about a liner profile. Each seal has a same shape including a peak having a rounded profile and a width narrowing toward the peak and defines a sealing surface arranged to form a secure interface with an interior wall of the socket that retains the suspension liner within the prosthetic socket. The textile material is located intermediate interior and exterior surfaces of the suspension liner that formed of one or more silicone materials in the area of the seals and the textile material defines the exterior surface of the suspension liner proximal and distal to the seals.

Abstract: A spinal orthosis includes posterior panels arranged with a flat spinal curvature to create a reverse three-point pressure system to the spine. The reverse three-point pressure system relieves pressure on the posterior side of the vertebrae beneficial for certain indications. Various arrangements allow for securing the posterior panel to the spinal orthosis. The spinal orthosis includes a belt member length adjustment system including belt members having end portions reducible in length and a belt panel adapted to secure to the end portion of the belt member reduced in length to form at least in part a belt circumference of the spinal orthosis.
