Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Among the various surgical techniques practiced the percutaneous discectomy occupies its space since the first description of the technique by Hijikata, 1975. Throughout, many techniques have been described. Studies indicate that the treatment was successful for pain and disability resulting from herniated disc associated with radiculopathy small.
However, some methods remove very small amounts of tissue with little change in volume of the disc. Thus, studies on the cadaver with Percutaneous Diskectomy by SpineJet ® showed more macroscopic changes of the disc with a predictable amount of removal and significant disc material.
The Percutaneous Diskectomy by SpineJet ® is a new technique of percutaneous diskectomy which creates a suction effect in tissues adjacent to the exit point of the fluid and the opening point of the collector. However, no studies have examined the effect of the Percutaneous Diskectomy by SpineJet ® in humans about the disk size after treatment or measures of disc degeneration by imaging methods or how these characteristics might correlate with clinical outcomes.
Thus, the study will compare outcomes of patients with contained or extruded disc herniation, with complaints of radiculopathy, concordant with the imaging findings. With treatment by surgical technique or the traditional by SpineJet ®, in order to determine whether percutaneous discectomy with SpineJet ® will produce results comparable to open microdiskectomy.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
OMicro
This group will be formed by randomization, which gets out surgery to open microdiscectomy
Open microdiscectomy
The open microdiscectomy, will be performed under general anesthesia in the prone position with horizontal. The level of the spine indicated for surgical treatment will be identified with the aid of fluoroscopy. An incision is made about the dorsal disc level involved with dissection of the paravertebral muscles on the side of disc herniation. After laminectomy and resection of part of the yellow ligament, partial discectomy is done under direct vision.
SJet
This group will be formed by randomization, and receive the discectomy procedure addressed by the technique of Percutaneous Diskectomy SpineJet
Percutaneous Diskectomy SpineJet
Percutaneous Diskectomy SpineJet be performed under local anesthesia, in which a needle is placed via percutaneous posterolateral extra-pedicular, below the neural foramen in the center of the disc, using the traditional approach for discography. The researcher will confirm the proper placement of the needle in front and side incidences on the fluoroscopy.
