Objectives: The purpose of this study is to analyze trends in domestic studies on pharmacopuncture therapy for treating cervical disease. Methods: This study was carried out on original copies and abstracts of theses listed in databases or published until July 2014. The search was made on the Oriental medicine Advanced Searching Integrated System (OASIS) the National Digital Science Library (NDSL), and the Korean traditional knowledge portal. Search words were 'pain on cervical spine', 'cervical pain', 'ruptured cervical disk', 'cervical disc disorder', 'stiffness of the neck', 'cervical disk', 'whiplash injury', 'cervicalgia', 'posterior cervical pain', 'neck disability', 'Herniated Nucleus Pulposus (HNP)', and 'Herniated Intervertebral Disc (HIVD)'. Results: Twenty-five clinical theses related to pharmacopuncture were selected and were analyzed by year according to the type of pharmacopuncture used, the academic journal in which the publication appeared, and the effect of pharmacopuncture therapy. Conclusion: The significant conclusions are as follows: (1) Pharmacopunctures used for cervical pain were Bee venom pharmacopuncture, Carthami-flos pharmacopuncture, Scolopendra pharmacopuncture, Ouhyul pharmacopuncturen, Hwangryun pharmacopuncture, Corpus pharmacopuncture, Soyeom pharmacopuncture, Hwangryunhaedoktang pharmacopuncture, Shinbaro phamacopuncture. (2) Randomized controlled trials showed that pharmacopuncture therapy combined with other methods was more effective. (3) In the past, studies oriented toward Bee venom pharmacopuncture were actively pursued, but the number of studies on various other types of pharmacopuncture gradually began to increase. (4) For treating a patient with cervical pain, the type of pharmacopuncture to be used should be selected based on the cause of the disease and the patient's condition.

Objective : To report the learning curve of percutaneous endoscopic lumbar discectomy (PELD) for a surgeon who had not been previously exposed to this procedure based on the period and detailed technique with a retrospective matched comparative design. Methods : Of 213 patients with lumbar disc herniation encountered during the reference period, 35 patients who were followed up for 1 year after PELD were enrolled in this study. The patients were categorized by the period and technique of operation : group A, the first 15 cases, who underwent by the 'in-and-out' technique; group B, the next 20 cases, who underwent by the 'in-and-out-and-in' technique. The operation time, failure rate, blood loss, complication rate, re-herniation rate, the Visual Analogue Scale (VAS) for back and leg were checked. The alteration of dural sac cross-sectional area (DSCSA) between the preoperative and the postoperative MRI was checked. Results : Operative time was rapidly reduced in the early phase, and then tapered to a steady state for the 35 cases receiving the PELD. After surgery, VAS scores for the back and leg were decreased significantly in both groups. Complications occurred in 2 patients in group A and 2 patients in group B. Between the two groups, there were significant differences in operative time, improvement of leg VAS, and expansion of DSCSA. Conclusion : PELD learning curve seems to be acceptable with sufficient preparation. However, because of their high tendency to delayed operation time, operation failure, and re-herniation, caution should be exercised at the early phase of the procedure.

Objective: Different types of interbody fusion cages are available for use in the surgical treatment of degenerative cervical diseases. The purpose of this study is to assess the technical feasibility, clinical efficacy and radiological results of intervertebral fusion with a carbon composite Osta-Pek frame cage (Co-Ligne AG, Switzerland) following anterior cervical discectomy. Methods: 41 patients (25males and 16females) with minimum 6months follow-up were included in the study. Disc height, cervical lordotic angle, segmental angle, and fusion rate were assessed by lateral radiographs. In this retrospective analysis, clinical outcome was assessed as evaluated according to Odom's criteria. Results: Fifty-four cages were implanted in 30 single-level, 9 two-level, and 2 three-level procedures. The mean disc height, cervical lordosis angle, segmental angle were $4.2{\pm}1.8mm,\;23.5{\pm}7.2^{\circ},\;2.3{\pm}3.3^{\circ}$ pre-operatively and $5.3{\pm}2.1mm,\;24.2{\pm}8.3^{\circ},\;3.8{\pm}3.5^{\circ}$ at 6months after the surgery. Six months after surgery, there was radiographic evidence of fusion in 92.7% (38/41) of the patients. According to Odom's criteria, 37 of 41 (90.2%) patients experienced good to excellent functional recovery. Conclusion: These clinical and radiological results suggest that the carbon composite Osta-Pek frame cages are safe and effective alternative to autologous bone graft after anterior cervical discectomy for treatment of degenerative cervical disease.

Objective : Discal cyst is rare and causes indistinguishable symptoms from lumbar disc herniation. The clinical manifestations and pathological features of discal cyst have not yet been completely known. Discal cyst has been treated with surgery or with direct intervention such as computed tomography (CT) guided aspiration and steroid injection. The purpose of this study is to evaluate the safety and efficacy of the percutaneous endoscopic surgery for lumbar discal cyst over at least 6 months follow-up. Methods: All 8 cases of discal cyst with radiculopathy were treated by percutaneous endoscopic surgery by transforaminal approach. The involved levels include L5-S1 in 1 patient, L3-4 in 2, and L4-5 in 5. The preoperative magnetic resonance imaging and 3-dimensional CT with discogram images in all cases showed a connection between the cyst and the involved intervertebral disc. Over a 6-months period, self-reported measures were assessed using an outcome questionaire that incorporated total back-related medical resource utilization and improvement of leg pain [visual analogue scale (VAS) and Macnab's criteria]. Results : All 8 patients underwent endoscopic excision of the cyst with additional partial discectomy. Seven patients obtained immediate relief of symptoms after removal of the cyst by endoscopic approach. There were no recurrent lesions during follow-up period. The mean preoperative VAS for leg pain was $8.25{\pm}0.5$. At the last examination followed longer than 6 month, the mean VAS for leg pain was $2.25{\pm}2.21$. According to MacNab' criteria, 4 patients (50%) had excellent results, 3 patients (37.5%) had good results; thus, satisfactory results were achieved in 7 patients (87.5%). However, one case had unsatisfactory result with persistent leg pain and another paresthesia. Conclusion : The radicular symptoms were remarkably improved in most patients immediately after percutaneous endoscopic cystectomy by transforaminal approach.

Objective : Few studies on the clinical spectrum of automated pressure-controlled discography (APCD)-defined positive discs have been reported to date. Thus, the present study was undertaken to analyze clinical parameters critical for diagnosis of discogenic pain and to correlate imaging findings with intradiscal pressures and pain responses in patients with APCD-positive discs. Methods : Twenty-three patients who showed APCD-positive discs were selected for analysis. CT discogram findings and the degrees of nuclear degeneration seen on MRI were analyzed in comparison to changes of intradiscal pressure that provoked pain responses; and clinical pain patterns and dynamic factors were evaluated in relation to pain provocation. Results : Low back pain (LBP), usually centralized, with diffuse leg pain was the most frequently reported pattern of pain in these patients. Overall, LBP was most commonly induced by sitting posture, however, standing was highly correlated with L5/S1 disc lesions (p<0.01). MRI abnormalities were statistically correlated with grading of CT discogram results (p<005); with most pain response observed in CT discogram Grades 3 and 4. Pain-provoking pressure was not statistically correlated with MRI grading. However, it was higher in Grade 3 than Grade 4. Conclusion : APCD-positive discs were demonstrated in patients reporting centralized low back pain with diffuse leg pain, aggravated by sitting and standing. MRI was helpful to assess the degree of nuclear degeneration, yet it could not guarantee exact localization of the painful discs. APCD was considered to be more useful than conventional discography for diagnosis of discogenic pain.

Objective : The purpose of this retrospective study was to determine which of the proximal adjacent segment disease (ASD) and distal ASD was more prevalent and what parameters is more related to ASD in proximal levels and distal levels after more than 2 levels fusions. Methods : The medical records were reviewed retrospectively for 856 cases. A total of 66 cases of ASD were enrolled. On preop magnetic resonance imaging, disc degeneration was measured at the upper and lower parts of surgically treated levels and confirmed by the commonly used Pfirrmann grade. Segmental flexibility in sagittal plane was embodied in segment range of motion (ROM) obtained through flexion and extension X-ray before surgery. Coronal angle was recorded as methods Cobb's angle including fusion levels preoperatively. For the comparison of categorical variables between two independent groups, the chi-square test and Fisher exact test were performed. Results : Proximal ASD and distal ASD were 37/856 (4.32%) and 29/856 (3.39%), respectively. The incidence of proximal ASD was relatively high but insignificant differences. In comparison between ASD group and non ASD group, proximal Pfirmman was higher in proximal ASD and distal Pfirmman was higher in distal ASD group (p=0.005, p<0.008, respectively). However, in the ROM, proximal ROM was higher in proximal ASD, but distal ROM was not different between the two groups (p<0.0001, p=0.995, respectively). Coronal angle was not quite different in both groups (p=0.846). Conclusion : In spite of higher frequency in ASD in proximal level in spinal fusion, it is not clear that incidence of ASD in proximal level is not higher than that of distal ASD group in more than 2 level thoracolumbar fusions. Not only Pfirrmann grade but also proximal segmental ROM is risk factor for predicting the occurrence of ASD in patients more than 2 level of thoracolumbar spine fusion operation excluding L5S1.

Lower motor neuron signs of hind limbs, anus and bladder were identified by history taking and physical examination in the 6.8 year-old mongrel dog and 2.6 year-old Cocker spaniel. The Cocker spaniel, also showed gradual cranial migration of neurologic deficit including respiratory paralysis. On plain radiography and myelography, intervertebral disc extrusion between L2 and L3, the infiltration of contrast medium into the spinal cord and cord swelling were found in the mongrel dog, and infiltration of contrast medium like hollowness of cord parenchyma was observed in the Cocker spaniel. On the basis of clinical signs and radiographic findings, they were diagnosed tentatively as acute myelomalacia. The Cocker spaniel died of respiratory paralysis on the following day. Decompressive surgery was performed on the mongrel dog and the extensive necrosis and hemorrhage were found at surgery. It was euthanized with the owner's consent because of the perceived poor prognosis. Histopathologic examination after autopsy confirmed acute diffuse hemorrhagic myelomalacia with the swelling and the inflammation of axon, showing hemorrhagic changes in the white matter and the grey matter.

Recently, some authors reported that discogenic low back pain should be regarded as a referred pain in respect of neural pathway. The afferent pathways of discogenic low back pain is transmitted mainly by sympathetic afferent fibres from the sinuvertebral nerves in the second lumbar nerve root. This pain arises from the lumbar intervertebral discs, and it had been transmitted mainly through the sympathetic afferent fibres contained in the second lumbar spinal nerve root. Second lumbar dermatome corresponds to the low back area. We experienced a case of low back pain which could not be controlled by conventional therapy and progressed wax and wane. The CT finding showed bulging disc between $L_4$ and $L_5$ and spinal stenosis in $L_4$ area. And epiduroscopic feature showed severe adhesion in $L_4$, $L_5$ and $S_1$. After we blocked $L_2$ root, pain score decreased 10 to 2. Therefore, the $L_2$ root block may be a useful diagnostic procedure as well as provide therapeutic value.

Objective : Cervicogenic headache (CGH) is known to be mainly related with upper cervical problems. In this study, the effect of radiofrequency neurotomy (RFN) for lower cervical (C4-7) medial branches on CGH was evaluated. Methods : Eleven patients with neck pain and headache, who were treated with lower cervical RFN due to supposed lower cervical zygapophysial joint pain without symptomatic intervertebral disc problem or stenosis, were enrolled in this study. CGH was diagnosed according to the diagnostic criteria of the cervicogenic headache international study group. Visual analogue scale (VAS) score and degree of VAS improvement (VASi) (%) were checked for evaluation of the effect of lower cervical RFN on CGH. Results : The VAS score at 6 months after RFN was $2.7{\pm}1.3$, which were significantly decreased comparing to the VAS score before RFN, $8.1{\pm}1.1$ ($p$<0.001). The VASi at 6 months after RFN was $63.8{\pm}17.1%$. There was no serious complication. Conclusion : Our data suggest that lower cervical disorders can play a role in the genesis of headache in addition to the upper cervical disorders or independently.
