1) 霊長類の赤核には, 局在する位置, 細胞構築, 連絡する回路構造など, その解剖学的特徴から明瞭な区分 (おもに大細胞性と小細胞性) が存在し, それぞれの機能には大きな差異がある. 2) 赤核の各区分における細胞群の発達の程度は, 哺乳類の中で大きなバリエーションがあり, 四足歩行動物では赤核脊髄路が, 高等霊長類では赤核オリーブ路が発達している. ヒトにおいてこの差異は極端であり, 前者の赤核脊髄路はほぼ退化し痕跡的となっている. このため, 齧歯類, ネコ, さらにはサルにおける実験結果から得られた知見を直接ヒトに外挿するには慎重を要する. 3) ヒトにおいて特異的に発達した小細胞性赤核の具体的, 詳細な機能についてはほとんどわかっていないが, その臨床病態の像や破壊損傷によって作出された実験動物の機能異常から, 小細胞性赤核は振戦への関わりがある.

Acute calcific tendinitis of the longus colli muscle presenting as an acute neck pain is not common. The present unusual case is a thirty eight year-old man who complained of an acute onset of neck pain. Lateral aspect of a plain X-ray of the neck showed a retropharyngeal space being dilated by 13.9 mm. CT/MRI delineated a partly calcified longus colli muscle with an effusion at the retropharyngeal space. Calcific tendinitis of the longus colli can be clinically misdiagnosed as retropharyngeal abscess, traumatic sequelae or infectious spondylitis. Correct radiographical diagnosis can be made by the presence of a calcified shadow anterior to C1-2 body, prevertebral soft tissue swelling and retropharyngeal effusion. His neck pain gradually ameliorated within 1 week by an administration of NSAIDs and neck rest. We present an uncommon case of acute calcific tendinitis of the longus colli muscle diagnosed by on unusual neck pain and the pathognomonic findings on the neuroimaging.

Objective : Odontoid fractures are the most common cervical injuries among the elderly population. We evaluated treatment outcome in 14 patients with odontoid fractures who were treated at our institute between 2003 and 2016. Additionally, in this report, we discuss the optimal treatment option for odontoid fractures in the elderly population and provide a literature review.  Results : Patient age ranged 19-90 (average, 60.6) years, and the patients included five (36%) octogenarians. According to Anderson’s classification, four cases (29%) were type II and 10 cases (71%) were type III odontoid fractures. Surgical intervention was performed in 12 cases, including anterior odontoid screw fixation in nine, posterior cervical instrumented fusion in four (including reoperation after anterior screw fixation in one), and conservative treatment with halo vest fixation in two. Moreover, 13 patients received radiographic follow-up, and 11 (85%) attained bone fusion. In octogenarians, three (60%) of five cases attained bone fusion through anterior screw fixation.  Conclusion : In the elderly population, tailor-made treatment is necessary according to systemic diseases, activities of daily living, and radiographic assessment of odontoid fractures in addition to Anderson’s classification.

脊髄の神経膨大を電気刺激や磁気刺激によって活動させると, 複数筋群の協調的活動による把持や歩行などの日常動作にみられるような機能的運動が誘発できる. 近年では, これを利用して身体麻痺のある者の脊髄に機能的刺激を施し, 麻痺した身体の随意運動機能を再建する試みが行われている. 本稿では, われわれの研究で開発した人工神経接続と呼ばれる神経細胞 (ニューロン) の働きをするコンピューターを用いた閉回路システムによる脊髄刺激の研究を紹介し, 身体麻痺のある者が自身の意思で脊髄刺激を制御することで随意運動機能を再建することを可能にした成果について報告する.

A 55-year-old woman felt a left shoulder pain and then left upper weakness 3 days after the pain onset. The patient was introduced to our department because of suspected cervical spondylosis. Muscle weakness was detected in her left deltoid, biceps brachii, and radial flexor carpi muscles. Cervical magnetic resonance imaging demonstrated a significantly expanded left vertebral artery in the C4/5, C5/6, and C6/7 intervertebral foramina. A septum was found inside the dilated vertebral artery, and true and false lumens were confirmed. The septum, expanded false lumen, and shrunk true lumen were also observed on contrast-enhanced computed tomographic (CT) angiography. The nerve root compression symptoms were thought to be caused by the dissection of the left vertebral artery. The symptoms were spontaneously improved after 6 months. The false lumen was markedly reduced on contrast-enhanced CT. We report a case of extracranial vertebral artery dissection presenting with radiculopathy, along with a literature review.

I reviewed the epidemiology and occurrence of traumatic cervical spine injuries of athletes in Japan and other countries, and noted the importance of initial assessment at the sports site, imaging diagnosis, and treatment of cervical spine injuries. From the global epidemiology of sports-related spinal cord injury, the frequency and cause of spinal cord injuries are different among countries, along with their respective characteristics. Taking prompt measures at the sports site is necessary to ensure safe patient handling and transport. However, as many people other than doctors are involved in sports events, the staff involved in these events should be prepared and practice emergency response measures. No major difference was found between athletes and non-athletes in regard to the treatment of cervical spine injury. However, athletes strongly hope for early return to active participation in their sport. Thus, surgical methods that are less invasive to soft tissues and involve strong fixation should be selected. However, further knowledge about evaluation and judgment for these athletes to return to their sport is needed. Many sports-related spinal cord injuries are preventable, and we must strive toward achieving zero incidence of spinal cord injuries. Thus, physicians attending to sports-related spinal cord injuries should both communicate more actively and supervise players of the team.

341 operated cases of lumbar disc hernia were analyzed. Cases of pure hernia were 87%, those with lumbar canal stenoses were 13%. The average age was 50.3 years-old and the male to female ratio was almost 2 to 1.The indication of surgery should be analyzed first, according to the patient's neurological status, complaints and the duration of leg pain. It also can be determined by examining the evidence of the findings of radiological images of neural compression. However, it may be also indicated, in consideration of the psychiatric aspects, excluding neurological degenerative diseases.In deciding the surgical plan, (whether it is limited to minimum surgery, or extended to the wide laminectomy), the surgeon should consider the following points; whether the patient is of working age or not, and whether his labor is physical work or not, for example.One of the other important points of surgical strategy is to make a change as promptly as possible from minimum laminotomy to the wide laminectomy, when the case of a large size hernia is accompanied with a severely narrow canal. This is in order to protect the nerve root, at the same time, as aiming for the maximum removal of the herniated tissue. Nevertheless, the rate of recurrence could not be decreased more than 2∼3%.The investigation of preoperative risk factors brings a decrease in the percentage of complications, such as, brain or heart vascular disorders, Exceptions would be postoperative infections or hematomas.
