MDT-0123 Japan Study

Image findings of symptomatic degenerative lesions from L2 to S1(MRI or myelography within 12 months prior to enrollment) and subjects who have been observed to have a neurological disorder by nerve root compression etc. as follows. A) Radiating pain in the lower limbs or buttocks, sensory disturbance, numbness, symptoms of weakness B) B. Nervous claudication

Subjects with degenerative disc disease with disc-derived low back pain, with or without leg pain, and the subject's medical history confirms disc degeneration [e.g., pain (symptoms of leg, back, or sciatic nerve distribution), functional deficits, and/or neurological defects)] and one or more of the following on image examination (e.g., CT, MRI, X-ray, etc.): A) Instability (defined as an angle of motion >greater than or equal to 5° and/or oscillation ≥4 mm, based on radiographs of anteroposterior flexion). B) Formation of osteophytes C) Decrease in the height of the intervertebral disc D) Thickening of ligamentous tissue E) Degeneration or herniation of the disc F) Degeneration of facet joints 3) Subjects with an ODI score of 35% or greater prior to the procedure. 4) Subjects with sufficiently mature skeletons. 5) Subjects who are 18 to 80 years of age or older at the time of surgery. 6) Subjects who has not responded to non-operative treatment (e.g., bed rest, physical therapy, medication, nerve block, manipulation, percutaneous electrical stimulation therapy (TENS)) for a period of 3 months. 7) Subjects who have received an adequate explanation of the details of this clinical trial and have given their written consent.
