A Case of Lumbar Spinal Canal Stenosis due to Achondroplasia

Orthopedics & Traumatology (1978)

S. Nishizima S. Hattori Masanobu Oyama S. Kawai H. Oda

A female achondroplastic dwarf was referred because of intermittent claudication, complained for 4 months, with numbness and dull sensation in her legs. She had slight bowel and rectum disturbance.This 45 year-old female was 112cm in tall, weighed 40kg, and had short arms and legs, hyperlordosis of the lumbar spine, and moderate kyphosis at the thoraco-lumbar level.Sensation was diminished over the L1 to L5 and S1 dermatomes.Lumbar puncture was unsuccessful and myelogram by cisternal puncture was done which revealed total block between the L1 and L2 level.Operation: Total laminectomy at L1 through L5 was carried out.The laminae were thick and pedicles were all short and thick. The dura and nerveroots were compressed extremely. After the laminectomy the widening of the canal was done including foraminotomy. There was no evidence of a ruptured disc. The dura was not opened. Post operative course was very good and four months later she can walk well without complaints in her legs.

A Study of Low Back Pain Land Carriage Workers from Questionnaire.

Orthopedics & Traumatology (1991)

Shintaro Toh H. Oda Toshihiko Taguchi Kou Tanekubo Tosikastu Tominaga

The purpose of this study was to investigate the relation between the low back pain and the circumstance of load carriage workers in Yamaguch prefecture from a questionnaire. It comprised 994 persons (849 men and 145 women) in the following three basic occupations: office worker, truck driver and luggage lifter. The 55.2% of office workers, 80.9% of truck drivers and 78.4% of luggage lifters had experienced low back pain. In this study, the percentage of men who had low back pain was 24.3% among office worker, 56.8% among truck driver and 50.0% among luggage lifter. The workers who treat the heavy load complain their low back pain in higher rate than those who don't treat it. Our data indicates that the incidence of low back pain become high in three basic occupations in comparison with the past data.

Follow-up Study of Whiplash Injury in Our Clinic

Orthopedics & Traumatology (1980)

F. Senzoku S. Hattori S. Kawai H. Oda Takashi Imagama

130 cases of whiplash injury were followed up directly or by mail from 4 years up to 13 years (average 8. 2 years).These cases were divided into 2 groups, which is, 75 cases with mild symptoms (improved less than 6 months after injury) and 55 cases with persistent symptoms (more than 6 months).Comparative study of 2 groups regarding age, sex, occupation, clinical pictures, x-ray findings and other factors were described.Of them, ten cases (7.7%) have being treated for 6.2 years in average.The factors which kept their symptoms remained for such a long time were discussed.

Mechanism of Vascular Tests in Thoracic Outlet Syndrome

Orthopedics & Traumatology (1978)

Takashi Imagama S. Hattori Masanobu Oyama S. Kawai Yasuo Azuma

Vascular tests for thoracic outlet syndrome are considered to be one of the important diagnostic aid in order to determine the localization and the severity of neurovascular lesion at the thoracic outlet region. However, the mechanism and significance of vascular tests are still unclear.This is to report our clinical and autopsial study to try to clarify the exact meanings of each vascular test.Materials are 72 cases in 48 patients with thoracic outlet syndrome (46 cases in 39 patients recieved first rib resection) and 21 cases of exploration in autopsy.Positive Adson's test, although the incidence is quite low, may suggest severe lesion at the scalen triangle. Eden's test indicate lesions at the costo-clavicular space. In this positive the clavicle moves most to the posteromedial direction among the various positions. Abduction-external rotation test and Wright's test show neurovascular compression mainly at the costo-clavicular region and partly at the scalen triangle. These positions make the neurovascular bundle tracted foward the lateral. Compression at the subcoracoideal region is not the main cause in Wright's test.

Enlargement of the spinal canal without laminectomy - An autopsied case.

Orthopedics & Traumatology (1984)

Akira Matsuoka S. Kawai K. Saiki H. Oda Takashi Imagama

Enlargement of the cervical spinal canal without laminectomy has been applied to one hundred cases with cervical myelopathy since 1971. A 58-year-old man, operated with this method 11 years ago, visited our clinic with acute paraplegia on Nov. 15, 1982. He died after two weeks and autopsy was performed. Multiple metastases of adenocarcinoma was diagnosed.At the autopsy the cervical spine was also examined. The enlarged spinal canal was still maintained and the laminae were very hard. Histologically, epidural connective tissue was loose compared with dorsal side of the laminae. Through this autopsied case it was confirmed that this operative method was effective for not only sufficient posterior decompression of the cord but also reconstruction of the posterior elements of the cervical spine.

The Circulatory Dynamics of the Cervical Epidural Space of the Patients with Cervical Osteochondrosis, Cervicoo-mo-brachial Syndrome

Orthopedics & Traumatology (1975)

S. Nitta S. Hattori Masanobu Oyama T. Isobe H. Oda

Forty patients with cervico-omo-brachial syndrome, twenty with cervical spondylotic myelopathy, twenty cervical spondylotic radicuolpathy and 20 normal controls were selected for this study.After catheter for cevrical epidural anesthesia had been placed in the cervlcai epidural space of these cases, circulation of the epidural space by R. I. and cervical peridurography were examined.From the results of our study, we suggest that one of the causes of cervico-omo-brachial syndrome is the lesion of the root area or unstable circulatory dynamics of the cervical epidural space.

A Case of Malignant Lymphoma Resembling to Osteomyelitis

Orthopedics & Traumatology (1975)

H. Oda K. Oda Y. Date

A 7-year-old boy with painfull swelling of the left elbow, right forearm and right acromio-clavicular joint. X-ray examinations showed irregular destruction and peiosteal thickening of the left humerus, right radius and ulna, and right clavicle.These findings were very similar to those of osteomyelitis.However, atypical eclls resembling to lymphocyte were seen 22% in peripheral blood and 85.2% in bone marrow.Malignant lymphoma (may be lymphosarcoma type) was diagnosed by the biopsy of the lesion.Chemotherapy was done and 27 months after onset he is now in complete clinical and hematologic remission of his disease.

Comparison of Myelographic Findings Before and After Surgery in Cervical Osteochondrosis

Orthopedics & Traumatology (1976)

S. Kawai S. Hattori Masanobu Oyama Hiroshi Hayakawa Yasuo Azuma

The preoperative myelographic findings of 131 patients operated for cervical osteochondrosis (105 operated by anterior fusion, 24 by laminectomy and 8 by foraminotomy) were compared with postoperative myelographic findings.There is generally a satisfactory correlation between the postoperative myelographic findings and the improvement of the clinical status of these patients.Both anterior fusior and laminectomy showed excellent or good improvement (more than 80%) of postoperative myelographic findings. It is necessary for getting satisfactory findings of post-operative myelography in anterior fusion to remove the posterior osteophytes and to correct alignment of the cervical spine.
