Objective : Fixation of the C1-2 segment is challenging because of the complex anatomy in the region and the need for a high degree of accuracy to avoid complications. Preoperative 3D-computed tomography (CT) scans can help reduce the risk of complications in the vertebral artery, spinal cord, and nerve roots. However, the patient may be susceptible to injury if the patient's anatomy does not match the preoperative CT scans. The intraoperative 3D image-based navigation systems have reduced complications in instrument-assisted techniques due to greater accuracy. This study aimed to compare the radiologic outcomes of C1-2 fusion surgery between intraoperative CT image-guided operation and fluoroscopy-guided operation. Methods : We retrospectively reviewed the radiologic images of 34 patients who underwent C1-2 fusion spine surgery from January 2009 to November 2018 at our hospital. We assessed 17 cases each of degenerative cervical disease and trauma in a study population of 18 males and 16 females. The mean age was 54.8 years. A total of 139 screws were used and the surgical procedures included 68 screws in the C1 lateral mass, 58 screws in C2 pedicle, nine screws in C2 lamina and C2 pars screws, four lateral mass screws in sub-axial level. Of the 34 patients, 19 patients underwent screw insertion using intraoperative mobile CT. Other patients underwent atlantoaxial fusion with a standard fluoroscopy-guided device. Results : A total of 139 screws were correctly positioned. We analyzed the positions of 135 screws except for the four screws that performed the lateral mass screws in C3 vertebra. Minor screw penetration was observed in seven cases (5.2%), and major pedicle screw penetration was observed in three cases (2.2%). In one case, the malposition of a C2 pedicle screw was confirmed, which was subsequently corrected. There were no complications regarding vertebral artery injury or onset of new neurologic deficits. The screw malposition rate was lower (5.3%) in patients who underwent intraoperative CT-based navigation than that for fluoroscopy-guided cases (10.2%). And we confirmed that the operation time can be significantly reduced by surgery using intraoperative O-arm device. Conclusion : Spinal navigation using intraoperative cone-beam CT scans is reliable for posterior fixation in unstable C1-2 pathologies and can be reduced the operative time.

The objective of this study was to identify pulmonary functional variations in relation to postural changes, lapse after changing position, and the use of abdominal band in the cervical cord injured. The subjects of this study were 19 quadriplegic patients who had been admitted to the department of the Rehabilitation Hospital, College of Medicine, Yousei University, from April, 1997 through May 3, 1997. A spiroanalyzer was used to measure pulmonary function in supine, standing, time after changing position, and recording to the position, application method, and tightness of the abdominal band. The data were analyzed by the repeated measure one-way ANOVA, and Wilcoxon signed rank test. The findings were as follows: 1. All phase of the patients' pulmonary function improved significantly in supine posture in contrast to standing (vital capacity by $0.46{\ell}$ and expiratory reserve volume by $0.09{\ell}$). 2. The longer the time lapsed from supine posture to standing, the patient's expiratory reserve volume, maximum ventilation volume, vital capacity, and forced expiratory volume increased. 3. When the patient lay in supine position, the maximum ventilation volume, vital capacity, and the forced vital capacity increased then the center line of the abdominal band was placed along iliac crest; on the other hand, when the patient was standing, placing the bottom line of the abdominal band along iliac crest increased the maximum ventilation volume, vital capacity, and forced expiratory volume. 4. In placing the abdominal band in the patients, leaving space between the top and bottom lines of the band helped increased in maximum ventilation volume, vital capacity, and forced vital capacity for patient in supine as well as in standing. 5. When placing the abdominal band to patients in supine posture, reducing the length of the band by 2.5% along the patient's waist line increased the patients' vital capacity, while reducing the length by 10% to patients in standing increased the maximum ventilation volume. The abdominal band should be placed in such a way that the bottom part of the band should be more tightly fastened while leaving enough room for a hand to be placed in between the body and the band for the top part of the hand. It should also be noted that in a supine position, the bottom line of the band should be placed along the iliac crest, while in standing, the center line should be placed along the iliac crest. The length of the band should also be reduced by 2.5% of the waist line in supine position, and in standing, the length should be reduced by 10%. It should also be noted that the pulmonary function of the patients should be measured at least 10 minutes after one position change.

토끼의 25분간의 척수허혈 모델에서 cyclosporin A의 신경보호효과를 신경병리학적 연관성과 면역조직화학적분석을 통하여 알아보고자 하였다. 대상 및 방법: 몸무게가 3.0 kg 전후의 뉴질랜드산 토끼를 이용하였고 복부 대동맥을 25분간 차단하였다. 32마리의 토끼를 무작위로 4군으로 나누어 대조군인 12군(n=8)과 17군(n=8)은 복부 대동맥 차단만 시행한 후 12군은 2일째, 17군은 7일째 희생시켜 신경학적 평가와 조직학적 검사를 시행하였다. 실험군인 Cs2군(n=8)과 Cs7군(n=8)은 복부 대동맥을 차단 후 재관류 15분 후에 cyclosporin A (25 mg/kg)를 정맥 주입한 후 Cs2군은 2일째, Cs7군은 7일째 희생시켜 신경학적 평가와 조직학적 검사를 시행하였다. 결과: 모든 토끼가 술 후 생존하였으며 술 후 2일째 신경학적 평가에 있어서는 군들 간 차이가 얼었으나 술 후 7일째 시행한 평가에서 복부대동맥 허혈 후 cyclosporin A를 투여한 Cs7군의 Tarlov score가 평균 $2.75{\pm}0.89$로 투여하지 않은 17군의 $1.25{\pm}1.39$에 비해 의미 있게 높아 신경학적 평가상 덜 손상을 받았음을 알 수 있었다(p<0.05). 또한 대조군 17군에서는 신경학적 평가가 2일째보다 7일째 악화하는 경향이었으나 통계학적으로 의미 있는 차이는 없었고 실험군 Cs7군에 있어서는 신경학적 평가가 2일째 $1.87{\pm}0.83$에 비해 7일째 $2.75{\pm}0.89$로 의미 있게 호전되었다(p<0.05). 모든 군을 조직학적으로 손상의 정도에 따라 등급을 매겼으며 신경학적 평가와의 상관관계를 분석하였는데 상관계수 -0.44로 조직학적 손상정도와 신경학적 평가사이에 유의한 관계가 있었다(p=0.009). 병리조직학적 등급을 4군 간 비교하였을 때 2일째 희생시킨 대조군과 실험군 사이에는 유의한 차이가 없었으나 7일째 희생시킨 17군은 조직학적 등급이 $2.13{\pm}1.36$이었으나 Cs7군은 $1.0{\pm}0.53$으로 두 군 간 유의한 차이가 있어 병리학적으로도 cyclosporin A를 투여한 실험군 Cs7군이 대조군 17군에 비해 덜 손상을 받았음을 알 수 있었다(p=0.039). 12군과 Cs2군에서 TUNEL 염색에 양성반응을 보이는 신경세포의 수는 12군이 $17.5{\pm}22.6$개였고 Cs2군이 $12.5{\pm}11.1$개로 통계학적으로 유의한 차이가 없었다. Heat shock protein-70 (HSP70)과 neuronal nitric oxide synthase (nNOS)에 대한 면역조직화학검사에서 실험군 Cs2군의 신경세포가 대조군 12군에 비해 HSP70과 nNOS의 과발현을 보였으며, 이는 통계학적으로 유의한 차이를 보였다(p<0.05). nNOS와 HSP70의 발현은 강한 연관성을 보였고(상관계수 0.91, p=0.000), nNOS를 발현하는 세포가 동시에 HSP70도 발현함을 확인할 수 있었다. 결론: 우리는 cyclosporin A가 토끼의 25분간의 척수허혈에 대해 척수보호 효과가 있었으며 이는 HSP70의 과발현과 연관이 있으리라 생각한다.

Background : Monoplegia is the paralysis of a limb. It is commonly caused by an injury to the cerebral cortex, and rarely caused by injury to the internal capsule, brain stem, or spinal cord. Most problems with cerebral cortex is derived from the occlusion of a brain cortex blood vessel due to thrombus or embolus. Objectives : This study is to see if there is a significance in thermal differences of acupoints in diagnosis and treatment of monoplegia on an upper extremity to test the validity of acupuncture and herbal treatment for it. Methods : By using Digital Infrared Thermographic Imaging(DITI), thermal differences$({\Delta}T)$ of acupoints on the upper extremity in a patient with monoplegia on the right upper extremity were measured after an attack of the disease. By giving Mangeum-tang(萬金湯) and treating the patient with acupuncture. the temperature changes of the upper extremity were examined through DITI and improvement was observed. Results : Compared with the left arm which suffered no such injury, the right recovered about 80% of sensation, and the grade of monoplegia improved from Grade O to Grade V. Also, the temperatures of right palmar-dorsal hand and the region of Weiguan(外關, Waiguan, TE5) were $1^{\circ}C$ and $1.45^{\circ}C$ higher than the same left region on admission day, but the thermal differences$({\Delta}T)$ narrowed to $0.5^{\circ}C$ by the last day. Conclusions : Results suggest that DITI screening is a reliable method of prognosis and that the time required for treatment can be estimated through this method in cases of monoplegia to an upper extremity. Also, progress in treatment is reflected in thermal differences of acupoints of the monoplegic upper extremity in accordance with the theory of meridian. This supports a role for acupuncture and herbal treatment for monoplegia.

Objective : DREZotomy is effective for the treatment of deafferentation pain as a consequence of root avulsion, postparaplegic pain, posttraumatic syrinx, postherpetic neuralgia, spinal cord injury, and peripheral nerve injury. We performed microsurgical DREZotomy to the patients with deafferentation pain and relieved pain without any serious complication. The purpose of this study is to evaluate the usefulness of the microsurgical DREZotomy for deafferentation pain. Methods : We evaluated 4 patients with deafferntation pain who were intractable to medical therapy. Two of them were brachial plexus injury with root avulsion owing to trauma, one was axillary metastasis of the squamous cell carcinoma of the left forearm, and the last was anesthesia dolorosa after surgical treatment(MVD and rhizotomy) of trigeminal neuralgia. Preoperative evaluation was based on the neurologic examination, radiologic imaging, and electrophysiological study. In the case of anesthesia dolorosa, we produced two parallel lesions in cephalocaudal direction, 2mm in distance, from the C2 dorsal rootlet to the 5mm superior to the obex including nucleus caudalis, after suboccipital craniectomy and C1-2 laminectomy, with use of microelectrode. In the others, we confirmed lesion site with identification of the nerve root after hemilaminectomy. We performed arachnoid dissection along the posterolateral sulcus and made lesion with microsurgical knife and microelectrocoagulation, 2mm in depth, 2mm in distance, to the direction of 30-45 degrees in the medial portion of the Lissauer's tract and the most dorsal layers of the posterior horn at the one root level above and below the lesion. Results : Compared with preoperative state, microsurgical DREZotomy significantly diminished dosage of the drugs and relieved pain meaningfully. One patient showed tansient ipsilateral ataxia, but recovered soon. There was not any serious complication. Conclusion : It may be concluded that microsurgical DREZotomy is very useful and safe therapeutic modality for deafferentation pain, especially segmentally distributed intermittent or evoke pain. Complete preoperative evaluation and proper selection of the patients and lesion making device are needed to improve the result.

Objectives : Skeletal muscle atrophy occurs in response to a variety of conditions. The unloading to muscle occurs clinically in limb immobilization, bed rest, spinal cord injury and peripheral nerve damage, resulting in significant loss of muscle mass and force production. Muscle disuse is accompanied by an increase in apoptotic signaling, which mediates some of the responses to unloading in the muscle. In this study we tested the hypothesis that Daeyeoung-jeon extract would improve muscle recovery after reloading following disuse. Method : Twenty young male Sprague-Dawley rats were used for the studies. The hindlimb immobilization was performed with casting tape to keep the left ankle joint in a fully extended position. No intervention was performed on the right leg and used as intact region. The Rats in Daeyeoung-jeon treated group (DYJ) were orally administrated Daeyeoung-jeon water extract, and rats of Control group were given with saline only. After 2 weeks of immobilization, all animals were sacrificed, and the whole gastrocnemius muscles were dissected from both legs. The morphology of right and left gastrocnemius muscles in both DYJ and Control groups were assessed by hematoxylin and eosin staining. Moreover, to investigate the immobilization-induced muscular apoptosis, the immunohistochemical analysis of Bax and Bcl-2 was carried out. Results : Daeyeoung-jeon represented the significant protective effects against the reductions of the left gastrocnemius muscles weight and average cross section area to compared with Control group. The treatment with Daeyeoung-jeon extract significantly reduced the immunoreactivity of BAX and increased the immunoreactivity of Bcl-2 in gastrocnemius muscle compared with Control group. Conclusion : Daeyeoung-jeon has protective effects against immobilization-induced muscle atrophy by regulating the activities of apoptosis-associated BAX/Bcl-2 proteins in gastrocnemius muscle.

Purpose: Ischial region is common site of pressure sore as well as greater trochanteric area. In general, ischial pressure sore associated with a large subcutaneous bursa often requires radical surgical treatment. The authors performed sclerotherapy using absolute ethanol which was considered as an alternative in treating recurrent ischial pressure sore. Methods: From may 2005 to February 2006, 11 ischial pressure sore patients were treated sclerotherapy using absolute ethanol. The authors performed sclerotherapy using absolute ethanol in 11 patients in whom the ischial sore has recurred despite of multiple radical surgical treatment. The patients' original disorders were spinal cord injury in 9 patients, cerebral palsy in 1 patient and giant cell tumor in thoracic vertebrae 1 patient. Results: Recurrence of pressure sore was not found in any patient during the follow-up period. The swap of the bursa taken before the surgery was germ cultured and compared with the discharge from an end of the inserted drain tube. The germ cultured results after the surgery were tested negative in all patients. Conclusion: This method involves causing the bursa to become scarred and closing it up by sterilizing, fixing, and denaturing by the pharmacologic effect of absolute ethanol instead of surgical excision of the bursa. We felt that aforementioned treatment modality may be considered as an alternative in treating recurrent ischial pressure sore.
