The new Thoracic Lumbar Support by RCAI features "two sizes fits all", cutting down on inventory and assuring proper patient fit. Each size offers two additional side panels, 3" and 6" to increase the circumference of the brace. This lightweight, TLSO design offers a low profile approach in the stabilization of the thoracic spine following injury, post surgery or disease states. It features an easy to apply design, including "back pack type" shoulder straps with patient friendly adjustments. Rigid, heat moldable Kydex® posterior/anterior panels and unique strapping design relieves load on intervertebral discs by lifting and holding the patient's weight, improving posture and relieving pain. Bendable side panels with metal stays conform to the patient's anatomy for comfort and support, and can be removed from the brace in the latter stages of the healing process.
