The ISO Preferred TLSO Flex with Trunk Support (BA220) provides trunk support extending from the sacrococcygeal junction and ends just below the scapular spine. The 17” rigid posterior plate combined with a soft anterior apron restricts gross trunk motion in the sagittal plane and produces intracavitary pressure to reduce load on the intervertebral discs. The padded shoulder strap system can be easily adjusted and is held in place with adjustable anterior chest straps fastened together by a quick release buckle. The back of the shoulder straps join together and continue down the center of the spine. This center strap can be adjusted to shorten or lengthen the strap utilizing the advanced hook and loop fastening to provide optimum fit. The rigid lateral panels can be easily angled to provide the best possible fit for a variety of patient body structures. Waist belts can be trimmed to fit sizes S to 2XL (up to 56” waist). Universal size. For 3XL to 5XL, the Large Kit for this item includes two (2) 9” belt extensions (ISO-BA202 Lumbar Belt Extension: Universal) and fits up to 74” waist.
