    Introduction: We wanted to evaluate the mechanisms of action and effectiveness of interspinous distraction in managing symptomatic Degenerative Lumbar disc herniation to determine the safety and efficacy of the New device implant and to avoid the last step of disc degeneration as described by White&Panjabi and Kirkalldy-Willis (1): Lumbar Instability.

    Methods: A prospective control trial ( 2012-2014) )Historic group + A new device (2012-2014 ) In a cohort of 100 patients with degenerative Lumbar disc degeneration 50 underwent surgical treatment in which the U device was placed and 50 control individuals were treated with discectomy alone. Patients underwent serial follow-up evaluations( clinical test ). and radiographic assessment were used to determine outcome Up to ten years follow-up data were obtained in all patients.

    Results: With a follow-up of Two years 90 % vs 60 % without evidence of any clinical or radiological instability. We have two years follow up for the new device at L5 s1 with good results so far.

    Conclusions: Our study Shows That The U new device was more effective than discectomy Group in the management of degenerative lumbar disc herniation.regarding lumbar instability.Easy learning curve ; at L5 / S1, depends on the Spinous Process of S1 Now with our device 90 % of the patients have implant the device Vs 60 % with Historic device.

    Patient Care: To avoid a new surgey in the future due to Lumbar instability

    Learning Objectives: Use the device in order to prevent or delay the clinical symptoms after discectomy : LAST step Lumbar Instability
