JOURNAL FREE ACCESSThe appearance on MRI of the pars interarticularis was evaluated in 13 patients with lumbar spondylolysis (L5) and contrasted with the backache. T1-weighted images showed the lysis better than T2-weighted images. Sagittal MR images were most useful in delineating soft-tissue lesions around the lysis. Stenosis of the neural foramen by hypertrophic soft-tissue change was recognized in the patient with severe backache, furthermore, the degree of stenosis seemed to correlate with that of the seventy of backache.View full abstractDownload PDF (1491K) -

JOURNAL FREE ACCESSEleven patients treated surgically for lumbar spinal canal stenosis associated with lumbar spondylolysis were reviewed to investigate the pathogenesis of the lumbar nerve root involvement in spondylolysis. In accordance with the location of neural compression, spinal canal stenosis was divided into three categories; subarticular recess stenosis(five patients), central and subarticular recess stenosis (two patients) and stenosis at the pars defect (four patients). Stenosis in more than half of the patients was found to be degenerative, as it is in usual cases, rather than due to spondylolysis.View full abstractDownload PDF (1744K) -

JOURNAL FREE ACCESSWe evaluated eleven Patients with foot drop associated with lumber canal stenosis who underwent operative therapy.
Subjects included seven males and four females, ranging in age from 51 to 71 years (mean 59.4).
Symptoms, piysical signs, myelogram, electromyogram (EMG) and prognosis of foot drop were evaluated.
Low back pain and numbness of lower limbs were seen in many cases but the pain was not severe. Sensory disturbance and muscle atrophy of the leg were seen in all cases with the sensory disturbance seen in many dermatomes.
The foot drop only improved in four cases, indicating a poor prognosis. In the cases where the foot drop did improve, the anterior tibial muscle weakness was poor in MMT, and action potentials were seen in EMG.View full abstractDownload PDF (283K) -

JOURNAL FREE ACCESSThree out of 63 patients who had a partial facetectomy developed postoperative spondylolisthesis and required secondary fusion. We studied the changes in the lumbar spine radiologically to investigate the cause of postoperative spondylolisthesis.
Two of the three cases were shown to have had their facet joint damaged during the surgical procedure and the remaining case had congenital degenerative spondylolisthesis. We stressed the importance of preventing such damage in these spondylolisthesis patients before receiving surgery.View full abstractDownload PDF (1916K) -

JOURNAL FREE ACCESSWe analyzed 39 cases of postoperative lumbar canal stenosis. Subjects included 25 men and 14 women with a mean age at the time of operation of 53.7 years. The period before recurrence of symptoms following the first operation ranged from 11 months to 34 years (mean: 9 years and 8 months). Duration of follow-up ranged from 1 year to 6 years and 2 months (mean: 2 years and 1 month).
In regard to the first operation in this series, Love's operation was done in 24 cases, fenestration in 5 cases, laminectomies in 6 cases and fusion operations in 4 cases.
Laminectomies were performed in most of the second operations. From operative findings CT and MRI the main cause of postoperative stenosis was shown to be new bone formation at the site of operation. In some cases the main cause was spinal fibrosis.
The preoperative average JOA score was 10.0±2.5 points, postoperative JOA score was 22.6±1.8 points.View full abstractDownload PDF (1320K) -

JOURNAL FREE ACCESSCeramic interspinous block (CISB) was used following anterior spinal fusion (ASF) in 72 patients with lumbar disc lesions during the penod January 1989-October 1991. This method allowed the post-operative period before ambulation could be initiated to be shortened by one week, and the time to discharge to be shortered by to weeks. Solid fusion was avalable in all cases with no collapse of bone graft occurring. CISB is very useful for achieving good results following ASF operations.View full abstractDownload PDF (2182K) -

JOURNAL FREE ACCESSAnterior spinal fusion is a useful method for lumbar spinal disorders even though the fusion rate is not particularly high. However it has been demonstrated that the fusion rate is greater than 98% when using the A-O screw and wiring method. We used this method for 12 cases. In our seres there were 4 cases with wire-loosening (28.6%), which can be dangerous for vessels as the wire edge is sharp. We Therefore investigated the possibility of using Tekimron thread as a substitute for the wire. In vitro, the inter-column pressure measured by pressure gauge showed that Tekmiron thread was as useful as the wire.View full abstractDownload PDF (4072K) -

JOURNAL FREE ACCESSWe studied five patients with chronic back or chronic back and leg pain, who had failed to respond to the usual forms of conservative managiment. Subjects included 3 males and 2 females with a mean age of 65.8 years (range: 53 to 78). We used Roy's technique for percutaneous rhizotomy of the posterior medial branch. To be considered a sultable candidate for facet denervation, the diagnostic test which involues facet nerve block with 0.5% Marcaine must be successful twice.
The blocks are performed in a fluoroscopy room with the patient prone, using AP and oblique fluoroscopy. The needle is inserted lateral to the inferior third of the facet joint and 0.5ml of 3.3% phenol glycerin is injected at each level. Relief of pain was achieved in all patients and no complications were noted.View full abstractDownload PDF (1021K) -

JOURNAL FREE ACCESSFive male patients with lumbar facet joint pain received percutaneous electrical denervation of the posterior median branch, using the Yamoguchi University method.
The mean age of the patients was 69 years, ranging from 52 to 80 years. The mean duration of follow-up was 8 months.
The effect of denervation can be judged by electromyography of the multifidus muscle.
All five cases had a good clinical course.View full abstractDownload PDF (1261K) -

JOURNAL FREE ACCESS(1) 48 patients with ante-position type instability (AP group), were followed-up for an average of 4.2 years (range: 8.7 to 1.2 years) to clarify the special features of the AP group.
(2) 6 patients were diagnosed as degenerative spondylolisthesis, with their anterior slip shown in all postures by motion X-ray.
In 42 patients (87.5%), the anterior slip was only recognized in the flexion position, thus many of the AP group have kept their situation unchanged.
(3) In all 6 degenerative spondylolisthesis patients, their lamina (Facet joints) in the A-P view of X-P were shown to be W, M or XM type. There were no X or U types.
(4) Comparing the changed and unchange group, we found the following resulls: The changed group had statishcally larger (more than 5 degrees) negative disc-angles in flexion (P<0.01), larger facer angles (P<0.05), smaller lordotic curves in their lumbar spine (P<0.01), bigger facet angles (P<0.05) than the unchanged group.
There were no significant differrences in age, range of motion, or lumbo-sacral angle between the two groups.View full abstractDownload PDF (1686K) -

JOURNAL FREE ACCESSA 45-year-old man with left sciatica was shown to have an abnormal shadow in the spinal canal on CTM.
Simple X-P view in the lumber spine reve aled vacuum phenomenon in L5-S1 inter-vertebral disc and myelography revealed a leff L5 root defect.
Myelo-CT showed a low density area in the spinal canal at the same level. Following root block, CT Showed the left L5 root to be compressed by the low density area. At operation, only a little disc material was found, but the patient's pain was gradually relieved post-operatively.View full abstractDownload PDF (1670K) -

JOURNAL FREE ACCESSDiagnosis and treatment of low back pain requires consideration to be given to psychological factors.
We conducted the Yatabe-Guilford test (Y-G test) in 32 patients with low back pain who presented to our outpatient clinic. The subjects included 14 male and 18 female patients with an average age of 44.9 years. Treatment results were evaluated using the JOA Scoving system and we studied the significance of the Y-G test. Moreover, a Rorschach test was conducted in one patient who was resistant to treatment, in order to study the relationship with the Y-G test.
Looking at treatment results in association with different characteristics of the Y-G test it was shown that B-type tended to have bad outcomes. Other results ware variable.
However, it is interesting that many subjects showed many Δ points in the Y-G test. One patient who was resistant to treatment was considered to have Alexithymia, judging from his Rorschach test. It was suggested that comparison between the Δ points of the Y-G test with the Rorschach test, might reflect the mind in an unconscious state.View full abstractDownload PDF (2648K) -

JOURNAL FREE ACCESSThere are few papers about the effectiveness of under-water exercise for low back pain. We studied the effect of such exercise in fifteen female patients with low back pain.
Physical Tests including the % fat, vital capacity, spinal functional test (K-W test) were carried out in the patients prior to beginning therapy, then three and six months after the initiation of therapy.
Clinical examination showed an improvement in the low back pain in all casee. Furthermore vital capacity increased and % fat decreased significantly.
Marked improvement was seen using the spinal functional test (K-W test) and the JOA score.
This study demonstrates that under-water exercise was very effective for the treatrment of patients with low back pain.View full abstractDownload PDF (306K)
