The EXPEDIUM® Advance Reduction Derotation System is a streamlined instrument set used in spinal surgeries to correct spinal deformities and scoliosis. The instrument set works as part of the EXPEDIUM® 5.5 Spine System to assist with both reduction and derotation, demanding surgical maneuvers that properly align a patient's spine. EXPEDIUM combines formerly separate instruments into one system, eliminating multiple instrument exchanges. It also provides a secure locking feature, quick release tabs and a streamlined instrument set.
