The DonJoy Duel TLSO is a unique prefabricated orthosis for post-operative, post-traumatic or chronic spinal pathology. The Duel TLSO provides full-circumferential rigid support from the scapular thoracic region (T2/T3) of the spine down to the sacrococcygeal junction (S1). The DonJoy Duel TLSO restricts forward flexion and encourages a hyperextension posture. The posture increases lumbar lordosis and resists lateral and rotary movements of the spine.
