1.Juvenile Posterior Bony Spur of the Lumbar Spine.
Journal of Korean Neurosurgical Society 1990;19(10-12):1314-1322
The bony spur formation without degenerative change in the lumbar spines in the young age group is quite interesting and not uncommon. This bony spur is different from the degenerative spur in the old age group in shape and mechanism of formation. The authors analyzed 111 patients with such posterior lumbar bony spur for recent 3 years and 9 months. The authors concluded that posterioly located Schmorl's node is a main cause of the bony spur without degenerative change at lumbar region. The authors advocated 'Juvenile spur' as a new disease entity.

Nonunion at the lumbosacral junction is a classic complication of long construct and deformity corrections. Iliac fixations have been extensively studied in the literature and have demonstrated superior biomechanical proprieties and lower complication rates. S2 alar iliac screws address the drawbacks of classical iliac screws but demonstrate similar biomechanical advantage. The main aim of this paper was to describe the S1 alar iliac (S1AI) screw fixation technique while evaluating our early results. S1AI screw fixation technique has the advantage of being able to achieve pelvic fixation without dissection to the S2 pedicle entry and is therefore a viable option for salvage of a failed S1 promontory screw.

OBJECTIVE: To examine the relative efficacy of three active exercise programs for work-related, chronic low back pain, and to observe to what extent the programs affected the mechanical stability of the lumbar region. METHODS: The subjects were 64 employees who were randomly divided into three groups to match the three active exercise programs which were performed 3 times a week for 6 months. All subjects were assessed with the same measurements at a pre-study examination, and then were reassessed at 2 weeks, 3 months and 6 months after the study. RESULTS: The pain intensity didn't show any significant difference among the three groups. However, the Oswestry Disability Index showed significant differences among the three groups at 6 months and the lumbar and thoracic exercise groups showed significant decreases compared to the general physiotherapy group (p<0.05). Maximal stretching with both hands in the overhead direction showed a significant difference among the three groups at 3 months and 6 months, and the thoracic exercise group at 6 months showed a significant increase in overhead stretching compared to the lumbar exercise and general physiotherapy groups (p<0.05). The lumbar region angle of inclination showed significant differences among the three groups at 2 weeks, 3 months and 6 months, with the thoracic exercise group being decreased significantly more than the lumbar exercise and general physiotherapy groups at 6 months (p<0.05). CONCLUSIONS: Exercise aimed at increasing thoracic mobility has an effect on lumbar stability. Furthermore, it is far more effective for lumbar stabilization than general physiotherapy and deep muscle strengthening lumbar exercise.

The bony spur formation without degenerative change in the lumbar spines in the young age group is quite interesting and is not uncommon. This bony spur is different from the degenerative spur in the old age group in shape and mechanism of formation. The authors analyzed 25 patients below 29 years old with such posterior lumbar bony spur. We concluded that posterioly located Schmorl's node is main cause of the bony pour in youn age group at lumbar region.

A rare case of spinal meningeal mesenchymal chondrosarcoma in 3 10/12 year old boy is reported. The tumor was located in lumbosacral region. Osteoplastic laminotomy was performed for total removal of tumor. The postoperative result was good and related literatures were reviewed.

There are reports showing considerable morphological abnormalities in the lumbosacral region, which are usually caused by certain diseases or simply by anatomical variations. It is possible that if a caudal block is performed in patients with these anatomical abnormalities it will either fail or another unexpected difficult situation will result. However, there is no case report regarding such issues. We experienced two cases of an unexpected dural puncture during a trial of caudal block, and one case in whom the dural puncture would most likely have been caused by a trial of caudal block. The dural punture was caused by morphological abnormalities in the lumbosacral region i.e., diffuse ectasia of the lumbosacral dura and a posterior sacral meningocele with an enlargement of the lumbosacral canal. The dural termination was located more distally in the potential dural puncture case than in the normal cases.

Compared to the lumbar region, it is very rare to encounter far lateral disc herniation in the cervical spine, and because of this, correct diagnosis before surgery is difficult: the condition can, however, be identified through the use of advanced MRI imaging techniques. In this case, far lateral disc herniation at C7-T1 was effectivery removed through posterior laminoforaminotomy, and soon after surgery, the patient's symptoms showed complete remission.

PURPOSE: To evaluate the reliance of standard AP radiograph and Ferguson radiograph in assessment of instrumented lumbosacral fusion mass with interobserver and intraobserver reproducibilities. MATERIALS AND METHODS: Postoperative standard AP radiograph and Ferguson radiograph were used to evaluate the fusion mass at the lumbosacral region of 44 consecutive patients who underwent posterolateral L4-S1 or L5-S1 instrumented fusion with pedicle screws & autogenous iliac bone graft. Ferguson radiograph was performed with the x-ray beam oriented toward the cranial portion at 40degree relative to the x-ray table. All observations were performed independently by three observers, blinded to the history, diagnosis, and patient identity. The fusion mass was graded as solid, pseudarthrosis or questionable. A second review was repeated at 2 weeks after index review. Interobserver and intraobserver reproducibilities were analyzed with Fleiss'method. RESULTS: Ferguson radiographs were more reliable than standard AP radiographs in detecting the fusion mass. Kappa values with the interobserver reproducibility were higher in Ferguson radiographs than in the standard AP radiographs. Kappa values with the intraobserver reproducibility of all three observers were higher in Ferguson radiographs than in the standard AP radiographs. The questionable fusion masses in the standard AP radiographs were revealed solid or pseudarthrosis in Ferguson radiographs in 67%. CONCLUSIONS: Ferguson radiograph is a more reliable method than standard AP radiograph in evaluating instrumented posterolateral fusion mass in lumbosacral region.

OBJECTIVETo show the space structures of Mingmen (GV 4) area and its adjacent tissues.
METHODSA frozen female corpse was cut into about 0.5 mm thick sections with a high-speed steel plane machine and photographed with digital and optical camera. Two 2-D transverse phase picture data sets were obtained and then were sequenced, matched, modified and divided. The 3-D reconstruction software was used to reconstruct the outline form of the lumbar part containing Mingmen (GV 4) to attain transverse phase picture data sets (3 022 sheets, 0.57 mm in thickness). The sagittal, coronal and different oblique plane were cut and the tissue structures in these pictures were analyzed. Thus, the reconstruction data sets were obtained.
CONCLUSIONAfter the structures of Mingmen (GV 4) were reconstructed with computer, the form of Mingmen (GV 4) can be dynamically observed from any angle and the space construction law of gross form of Mingmen (GV 4) can be proved.

Lumbar spondylolysis and spondylolisthesis are common spinal disorders that most of the times are incidental findings or respond favorably to conservative treatment. In a small percentage of the patients, surgical intervention becomes necessary. Because too much attention has been paid to novel surgical techniques and new modern spinal implants, some of fundamental concepts have been forgotten. Identifying that small but important number of patients with lumbar spondylolysis or spondylolisthesis who would really benefit from lumbar surgery is one of those forgotten concepts. In this paper, we have developed an algorithmic approach to determine who is a good candidate for surgery due to lumbar spondylolysis or spondylolisthesis.
