This study compared the degree of disc degeneration of intervertebral disc between normal disc and disc disease using Magnetic Resonance images of tholacolumbar and lumbar vertebrae in dogs. The sample population consisted of 72 dogs and 188 intervertebral discs. These dogs were divided into four groups according to MRI criteria: normal, disc protrusion, disc extrusion, and fibrocartilaginous embolism. The Pfirrmann classification developed by Pfirrmann for use in human medicine was used to assess the degree of disc degeneration. Statistical analysis revealed that disc diseases had a significant difference in the degree of disc degeneration compared to normal discs in the intervertebral disc. Fibrocartilaginous embolism was found to have a relatively low disc degenerative change compared to two other disc disease groups, disc protrusion and disc extrusion. Disc degeneration in the disc extrusion group was slightly higher than that in the disc protrusion group, although the difference between the two groups was not statistically significant.

Signalment: A 7-month-old, female domestic shorthaired cat was presented for acute pelvic limb paraparesis. Results: There was no abnormality on survey radiographs and blood analysis, however neurological examination revealed proprioception positioning and hopping was absent in the pelvic limbs. Also, anal tone and perineal sensation were reduced. Magnetic resonance (MR) imaging showed nucleus pulposus dehydration and disc protrusion at T12-T13. Ill-defined diffuse lesion was found at T10-L2 level and it showed isointense on T1-weighted images and hyperintense on T2-weighted and FLAIR images. This lesion was considered as edematous lesion secondary to disc protrusion. The presumptive diagnosis was focal spinal cord edema associated with intervertebral disc protrusion. A traumatic aetiology was suspected. The cat was treated corticosteroids and analgesic and clinical sign improved following 9 days of treatment. Clinical relevance : Intervertebral disc protrusion is rare disease in a cat. However, it could be considered as a cause of paraparesis in cats.

The classification of herniated intervertebral lumbar disc type is clinically important, as treatment method may be slightly different according to the type of herniated intervertebral disc. When 450 patients who suffered from herniated intervertebral lumbar disc were tested with Magnetic Resonance Imaging (MRI) to find out the type of herniated disc, the following findings were given : 1. The age of the patients investigated ranged from 15 to 83, and their mean age was 40. 2. The male patients were twice as many as the female patients, since the ratio of males to females was 300 : 150. 3. 118 patients suffered from a single herniated disc, and 332 patients were attacked with multi-herniated disc. 4. The types of single herniated disc were a protrusion for 50 patients (40%) and an extrusion for 40 patients (34%). The part of being herniated was an intervertebral disc between $L_4-L_5$ for 95 patients(80%) and the same disc between $L_5-S_1$ for 22 patients(19%). 5. The types of multi : -herniated disc were an protrusion for 67 patients(20%) and an extrusion for 70 patients(21%). Besides, 90 patients (28%) were the case that protrusion and extrusion coexisted simultaneously. The parts of being herniated were $L_3-L_4,\;L_4-L_5$ and $L_5-S_1$ for 53 patients(16%), $L_3-L_4$ and $L_4-L_5$ for 57 patients(17%), and $L_4-L_5$ and $L_5-S_1$ for 139 patients(42%).

Three dogs referred to Veterinary Medical Teaching Hospital, Seoul National University were diagnosed as intervertebral disc disease. Physical examination, neurologic examination, survey radiograph, and myelography were performed in patients. Case 1 showed narrowing intervertebral space and calcified intervertebral disc material in survey radiograph. Case 2 showed increased opacity in the intervertebral opacity in survey radiograph. All of 3 cases showed extradural pattern during myelography. In survey radiography, radiographic signs consistent with intervertebral disc herniations include narrowing of the disc space and the dorsal intervertebral articular process joint space, small intervertebral foramen, increase opacity in the intervertebral foramen and extruded, mineralized disc material within the vertebral canal. Myelography is useful for evaluating the spinal cord and the cauda equina. Indication for myelography includes confirming a spinal lesion seen or suspected on survey radiograph, defining the extent of a survey lesion, finding a lesion not observed on survey radiograph, and distinguishing between surgical and nonsurgical lesion. In presentcases, two of three cases show radiographic signs of IVDD with survey radiograph and all of three case show extradural pattern during myelography. It is observed that intervertebral disc disease is one of the most important indication for radiographic examination and myelography of the vertebral column of small animals.

Objectives : This study is planned to classify correlation between thoracic kyphosis angle and prevalence of cervical intervertebral disc. Methods : We Measured the thoracic kyphosis angel of the 110 men and 179 women patients with neck pain in 00 Korean Medicine Hospital. We use Cobb's angle method and Thoracic cage dimension method for measuring the thoracic kyphosis. And We use Magentic Resonance Imaging(MRI) for classifying the patient who has cervical intervertebral disc or not. Results : 1. There was statistical difference on the thoracic cage dimension with gender(P<0.001), while there was no statistical difference on Cobb's angle with gender(P=0.882). 2. Age and thoracic cage dimension(r=0.383) is statistically more correlative than age and cobb's angle(r=-0.59). Conclusions : 1. Thoracic cage dimension and gender, Thoracic cage dimension and age were statistically concerned on patient who has neck pain, while Cobb's angle had no statistical correlation with age and gender. 2. There was no statistical difference on the Cobb's angle and Thoracic cage Dimension between patient who has one or more cervical disc herniation(Protrusion disc, Extrusion disc) segment and patient who didn't have cervical disc herniation(Protrusion disc, Extrusion disc) segment.

Background: The aim of this study was to examine whether the effects of acupotomy therapy were beneficial for the treatment of protrusion of lumbar intervertebral disc. Methods: The number of patients (n = 80) were equally assigned into treatment group and control group. Treatment group was given acupotomy therapy twice a week, and control group was given acupuncture 3 times a week, for 4 weeks. The beneficial effect and changes in score of the Japan Orthopedic Association (JOA) for low back pain were observed. Results: Among 40 cases in the treatment group, there were 25 (62.5%) with an excellent effect, 13 (32.5%) with good effect, 1 (2.5%) with a medium effect and 1 (2.5%) with poor effect, with the total experiencing an excellent/good effect of 95.0%. Among 40 cases in the control group, there were 11 (27.5%) with an excellent effect, 17 (42.5%) with good effect, 10 (25.0%) with a medium effect, and 2 (5.0%) with poor effect, with an excellent/good rate of 70.0%. The result of the rank sum test showed Z = -4.923, p < 0.05 in the comparison, indicating a significantly better outcome following acupotomy compared with acupuncture. JOA scores increased in both groups after treatment (p < 0.05), which was more significant in the acupotomy treatment group (p < 0.05). Conclusion: Acupotomy therapy has a beneficial effect on protrusion of lumbar intervertebral disc.

Background: Provocative discography (PD) is a test that is useful in diagnosing discogenic pain (DP). In this study, to diagnose DP, we used a posterolateral approach of needle placement and followed pressure criteria laid down by the Spine Intervention Society. The aim was to identify the correlation between magnetic resonance imaging (MRI) findings (desiccation, high intensity zone and change in shape and size of the disc) and the results of PD. Methods: Records of 50 patients who underwent PD for DP were analyzed. A total of 109 PDs were performed, with 54 suspect and 55 control discs. Alternate pain generators were ruled out. Results: A total of 35 suspect discs were positive on PD. The mean disc pressure in the suspect disc was 31.9 ± 7.9 psi (range, 15-44). Of the 50 patients who underwent PD, 35 had positive MRI findings. A significant positive correlation was found only between disc desiccation and discography result (r = 0.6, P < 0.001). Logistic regression analysis revealed that only desiccation successfully predicted the result of discography (OR = 26.5, P < 0.001); a high intensity zone and a disc protrusion/extrusion had an OR 2.3 and 1.24, respectively. Disc desiccation of Pfirmann grade 3 or more had a sensitivity and specificity of 0.93 and 0.64 respectively in identifying painful discs; the positive likelihood ratio was 2.58 while the negative likelihood ratio was 0.11. Conclusions: In patients with DP, disc desiccation is the most useful MRI feature that predicts a painful disc on PD.

Objectives : This study was performed to assess the effectiveness of conservative Korean traditional medical treatment on lumbar intervertebral disc herniation in 12 adolescents. Methods : Data were collected from adolescent patients diagnosed with lumbar intervertebral herniation by MRI, hospitalized at Jaseng Korean Medicine Hospital from January 1, 2014 to December 31, 2015. A total of 12 patients were included in the study. Patients were treated by acupuncture, pharmacopuncture, electroacupuncture, herbal medicine, chuna manual therapy, physical therapy during hospitalization period. To measure treatment outcomes, a verbal numerical rating scale (VNRS), Oswestry disability index (ODI), range of motion (ROM), Straight leg raising test (SLR), and EQ-5D were used. Results : The average age of the participants was $16.05{\pm}1.62$. The average of duration of symptom was $19.25{\pm}26.83(weeks)$ and the average length of hospitalization was $23.8{\pm}16.4(days)$. 2 patients (17 %) suffered from only lumbar pain, while 10 patients (83 %) suffered from lumbar and leg pain. No participant suffered from only leg pain. 8 patients (67 %) were diagnosed with disc herniation in one segment, and 4 patients (33 %) were diagnosed with disc herniation in multiple segments. A total of 17 disc segments (28 %) were herniated. The most herniated lumbar level was L4-5. 3 segments were diagnosed with bulging (17 %), 6 with protrusion (35 %), and 8 with extrusion (47 %). Extrusion was the most frequent herniated type. After treatment, the average VNRS of lumbar pain significantly decreased from $5.58{\pm}1.62$ to $2.91{\pm}1.56$ (p<0.001) and the average VNRS of leg pain significantly decreased from $5.16{\pm}2.51$ to $3.08{\pm}1.8$ (p<0.001). ODI significantly decreased from $48.87{\pm}18.72$ to $28.57{\pm}15.05$ (p<0.05), and EQ-5D significantly increased $0.58{\pm}0.31$ to $0.80{\pm}0.12$ (p<0.05). Range of flexion significantly improved from $61.25{\pm}32.62$ to $68.33{\pm}26.22$ (p<0.05). Conclusion : Conservative Korean Traditional Medical Treatment may be effective in the treatment of lumbar intervertebral disc herniation in adolescence. However, more case reports and clinical research are needed.
