OBJECTIVE: To introduce a new spinal internal fixation system, @entity580 ( @entity580 ), and to investigate its early clinical outcomes. METHODS: The preliminary clinical outcomes of 15 @entity1 with thoracolumbar or lumbar @entity1635 treated by anterior spinal fusion with @entity580 instrumentation were studied retrospectively. Fourteen @entity1 were diagnosed as @entity2112 and 1 as @entity4094 . RESULTS: Preoperatively, the Cobb's angle on the coronal plane was 55.8 degrees (range 35 degrees to approximately 78 degrees), and 14 degrees postoperatively, with an average correction of 74.8%. The average unfused thoracical curve was 35.9 degrees preoperatively (range 26 degrees to approximately 51 degrees) and 21.8 degrees (10 degrees to approximately 42 degrees) postoperatively, with 40% correction. The sagittal curve of lumbar was kept physiologically, preoperative 27.9 degrees and postoperative 25.7 degrees respectively. The trunk shift was 13.4 mm (5 to approximately 28 mm) preoperatively and 3.5 mm (0 to approximately 7 mm) postoperatively. The averaged apic vertebra derivation was 47.8 mm (21 to approximately 69 mm) before operation and 10.8 mm (3 to approximately 20 mm) after operation. The distance of C7 to center sacrum vertical line (CSVL) was 19.5 mm (16 to approximately 42) preoperatively and 11.3 mm (0 to approximately 32 mm) postoperatively. The apical vertebra rotation was 3 degree in 15 @entity1 preoperatively, and were improved to normal in 10 @entity1 , 1 degree in 4 @entity1 , and 2 degree in 1 @entity1 postoperatively. None had @entity16 and @entity281 . Only 1 @entity1 complained a cool feeling in the low extremity of concave side, and the symptom vanished at 3-month followed up. CONCLUSION: If used appropriately, @entity580 anterior spinal system is a good teatment for low thoracic or @entity1514 .
