The comparison of the contrast medium X-ray of radical capsular with the results of operation of the lumbar spinal disc herniation showed that the diagnosis of the spinal disc herniation by the contrast medium X-ray was suitable with the results of the operation of the lumbar - spinal disc herniation in which the lumbar spinal disc herniation in the vertical of L4, L5, L5S1 and double herniation were 70.7%, 13.3% and 8.8%, respectively. The unsuitable rate of diagnosis between them was 5.7%. There were 11 cases that were the false negative due to press of extradural vein and the flaval ligament inflammatory. The X-ray technique should be implement in 3 positions: vertical, side and inclined 3/4 to prevent the missing of lesion

Thoraco Lumbar spine injury is about 3-5%. But the neurological lesion and sequela was very severe, many of patients became handicap. Early intervention with pedicle screws and plates give us good result for patients with Thoraco Lumbar spine injury

11 patients with the lumbar vertebral slip due to degeneration (male: 1; female: 10) ages of 39-70 received the surgical treatment by using fixation and posterior bone fusion. The results have shown that the average time for monitoring was 23.27 months; pain free (90.91%) pain relief (9.09%), out door normal walking (90.91%) home walking (9.09%). Technique of bone fusion: postero lateral fusion (81.82%), fusion of bony head (70%) posterobalteral fusion and fusion of bony head (70%), without fusion of bony head 30% and without posterolateral (18.18%). The conclusion: the fixation with instrument and bone fusion for treatment of lumbar vertibral slip due to the degeneration found the good and encoraged results

Dynamic stabilization technology has increasingly become the hot spot in basic and clinical research for treating lumbar degenerative diseases. As one kind of dynamic stabilization technology,dynamic neutralization system (Dynesys) keeps the spinal motion ability and improve clinical symptoms of patients, moreover, it shows a certain advantage in delaying the degeneration of adjacent segments. From the available documents,the preliminary biomechanical and clinical results of Dynesys were optimistically, it has become another choice in treating the lumbar degenerative diseases besides the lumbar fusion, and it primarily applies to the treatment of mild to moderate lumbar degenerative disease. However, it lacks a mechanism to maintain and restore the lumbar lordosis and patients need active stretching to achieve lordosis. What's more, how to extend the service life and prevent complications remain to be solved, the long-term effect and the mechanism of delaying the adjacent segment degeneration need further investigation. In this article, the design principle, biomechanical research, clinical outcome and clinical application of Dynesys was reviewed.

Background: Spinal injury is a severe, common injury in surgical emergency. In Vietnam, there are only few studies on fixing thoracolumbar spine. Objectives: To assess and to provide some preliminary remarks on the results of emergency surgery fixing thoracolumbar spine, performed in Viet Duc Hospital. Subjects and method: A descriptive, prospective study was conducted on 31 patients with thoracolumbar spinal injury (22 males, 9 females, the average age 35 years old), operated in Viet Duc hospital from January, 2005 to July, 2006. Results:Patients with thoracolumbar spinal injury was common seen in working ages. 45.2% of them were farmers. 21/31 patients caused by falls. For non-complete paralysis patients, emergency surgery was required as soon as possible. The most of patients recovered completely. For thoracolumbar spinal injury, Burst-fracture and non complete paralysis, surgery with anterior way should be performed to release cord compression and bone graft. For cases of Burst-fracture, no paralysis, surgery with anterior way helped bone fractures were easy to heal, avoiding postoperative humpback recurrence. Conclusion: Combined surgery with 2 ways (before and after) guaranteed fixing spine, making bone healing was more better in case of rupture of vertebrae, releasing directly spinal cord and facilitating to the best recovery of the spinal cord.

OBJECTIVETo explore the advantages and indications of the paraspinal approach by anatomical study and clinical application.

METHODSThe anatomical data and clinical practice of 27 cases were analyzed to explore the accurate approach between the paraspinal muscles and the structure of ambient tissues, as well as the results of clinical application of paraspinal approach. The operation time, blood loss, incision length, radiographic result (Cobb angle, height of anterior edge of the vertebrae) were compared with those in 24 cases treated by traditional approach.

RESULTSComplete exposure of the facets could be easily performed by identifying natural cleavage plane between the multifidus and longissimus muscles. The natural muscular cleavage was (1.47+/-0.23) cm lateral to the midline for females, and (1.64+/-0.35) cm for males at T(12) level. The distance was (3.3+/-0.6) cm lateral to the midline for females, and (3.7+/-1.0) cm for males at L(4) level. In paraspinal approach group, the operation time was (76.2+/-15.7) min, blood loss was (91.6+/-16.9) ml and incision length was (7.6+/-0.8) cm. In traditional approach group, the operation time was (121.4+/-19.6) min, blood loss was (218.7+/-32.3) ml and incision length was (17.4+/-2.1) cm. To compare paraspinal approach with traditional approach, the operation time, blood loss and incision length had statistical difference (P less than 0.05) and the radiographic result (Cobb angle, height of anterior edge of the vertebrae) had no statistical difference (P larger than 0.05).

CONCLUSIONSWhen the paraspinal approach is performed through natural cleavage plane between the multifidus and longissimus muscles, there are no wide muscular disinsertions, leaving the supraspinous and interspinous ligaments intact. The distance of natural cleavage to the midline is different at T(12) and L(4) planes. By this approach, the facet joints can be explored easily and completely, and a clear surgical field will be available for the placement of pedicle screws. As a minimally invasive approach, it can be widely used in thoracolumbar spine surgery.
