Purpose: This study is to investigate the alleviation effects of Daebangpoongtang in LPS induced arthritis in mice knee joint. Methods : Daebangpoongtang was chosen to treat the arthritis caused by injecting $300{\mu}g/kg$ LPS to mice knee joint. The control group had no treatment, while the LPS group was injected $300{\mu}g/kg$ LPS to mice knee joint and the DBP group was oral administrated of Daebangpoongtang. After injection of $300{\mu}g/kg$ LPS to mice knee joint, the alteration of synovial lining cell, vessel, fibrosis, distribution of collagen fiber, fibroblast, mast cell, infiltration of inflammation component cell and distribution of ICAM and VCAM was observed by light microscope(BX50). Results : In the DBP extract treatment group, the distribution of vessel, the enlargement of synovial lining cell layer, the synovial lining cells with filopodia, the fibrosis, the distribution of fibroblast in synovial membrane, the distribution of TCAM and VCAM on the knee joint was less than that of LPS group. Infiltrated lymphocyte into the apical surface had not observed in the DBP extract treatment group. The distribution of mast cell was as same as control group(no treatment group) and it showed granulated type. Conclusion: According to the above results, it might be considered that the administration of Daebangpoongtang has a curative effect on synovial membrane injury in arthritis by inhibiting increase of vessel, cell adhesion molecule(ICAM and VCAM) in LPS induced arthritis.

Objectives: To explore the quality of life in patients with temporomandibular disorders and to evaluate it in terms of source and duration of the pain. Methods: A total of 61 patients with temporomandibular disorders participated in this study. According to pain source, they were divided into 2 groups, masticatory muscle pain (MMP) group and intracapsular pain (ICP) group. And each group was divided into acute phase group (pain duration <6 months) and chronic phase group (pain duration=6 months). The Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) was used to measure patients' quality of life. The scores for eight-scale profile and the physical component summary (PCS) and mental component summary (MCS) of the SF-36 were compared between groups (MMP vs. ICP and acute vs. chronic). Student t-test was used to analyze the difference of the scores of the SF-36 between MMP and ICP groups. Results: MMP group showed significantly lower score in the 3 scales of the SF-36 (Role limitations due to emotional problems, Vitality, Bodily pain) when compared to ICP group. In acute phase there was no significant difference between MMP and ICP group in PCS as well as MCS scores, but in chronic phase MMP group showed significantly lower MCS score than ICP group. Conclusions: The masticatory muscle pain in patients with temporomandibular disorders,negatively influences the quality of life especially in chronic phase, and the mental components of quality of life are significantly interfered in the TMD patients with chronic masticatory muscle pain.

Purpose: We introduce arthroscopic assisted core decompression for humeral head osteonecrosis. Operative technique: After diagnostic shoulder arthroscopy is performed using posterior and anterior portal, we make a 2 cm lateral skin incision approximately 3 cm distal to 1/3 of lateral margin of the acromion and place short gray cannula to prevent adjacent soft tissue injury when insert guide pin. Under C-arm fluoroscopic and arthroscopic guidance, 3 to 4 guide pins are inserted toward the necrotic area. Then we perform drilling using 7.0 mm reamer. Conclusion: We believe this technique is a less invasive approach and avoids the complications comparing to deltopectoral approach. Arthroscopic assisted core decompression is an effective procedure in management of early stage of the humeral head osteonecoris.

Coracoid impingement syndrome results from abnormal contact between the anterosuperior humerus and the coracoacromial arch. The coracoid impingement may occur from traumatic, idiopathic, or iatrogenic causes. Traumatic causes of coracoid impingement include fractures of scapular neck, coracoid process or lesser tuberosity. Coracoid impingement due to lesser tuberosity malunion is a rare disease and most of them were treated by open procedures. The authors present a case of coracoid impingement caused by malunion after isolated lesser tuberosity fracture which was treated by arthroscopic coracoplasty with percutaneous screw fixation.

Purpose: To identify the damage of the articular cartilage and analyze the clinical results of the partial medial meniscectomy. Materials and Methods: From January 2001 to December 2004, forty-eight patients in the degenerative arthritis and medial meniscal tear of knee who undertook arthroscopic partial meniscectomy and were able to keep pace with the times follow-up for more than 3 years were enrolled in this study. Six cases were men and 42 were women, and the mean age was 55.7 years (40~78 years). The patients were classified into two groups according to the Outerbridge grade. Grade I and II were classified into group 1 and grade III and IV into group 2. Group 1 included 30 cases and group 2 included 18 cases. The result were analyzed according to the Tapper & Hoover classification and Lysholm knee scoring scale. And we measured the distance of medial joint space in standing anteroposterior (AP) view of both sides at the pre-operative and the last follow-up. Results: According to the Tapper & Hoover classification, 28 cases were excellent, 7 cases good, 8 cases fair, and 5 cases poor. Among group 1, 25 cases were excellent, 2 cases good, 2 cases fair, 1 case poor. However, among group 2, 3 cases were excellent, 5 cases good, 6 cases fair, 4 cases poor. Average Lysholm knee score was improved from 62.4 preoperatively to 94 postoperatively in group 1, and from 58 preoperatively to 77.9 postoperatively in group 2. The joint space narrowing showed no statistically significant difference in both knees standing AP view. Conclusion: The arthroscopic partial meniscectomy for a patient with the degenerative articular cartilage was an effective treatment. However, we could not satisfy the results, in cases of Outerbridge grade III and IV. In grade III and IV, the partial meniscectomy was not aggravated the cartilage damage.

In lateral projection imaging method of knee joint, a method that adjusts the incidence angle of central X-ray toward the head side to $5{\sim}7^{\circ}$ in true lateral position which is existing recommended is called imaging method A, Method of imaging the central X-ray perpendicular to the horizontal plane of the examination table toward the knee is called imaging method B, and a method in which the central X-ray is perpendicularly applied to the joints while the lateral side of the distal tibia is compensated by radiolucent materials is called as method C. After tests each imaging method to classified study subject respectively, the joint space distance and the distance between lateral and medial condyle of femur were measured and compared as the quantitative index from the three imaging methods. In addition, the convenience of each imaging method was confirmed through questionnaires to practician. According to the result of the quantitative index, there is no statistically significant difference in imaging method A and C(p>0.05). However, imaging method B showed a significant difference in both A and C(p<0.05). As a result of evaluating the convenience of the imaging method, imaging method A was relatively assessed lower in all items than imaging methods B and C, and as a small difference, imaging method B is assessed higher than C. In this study suggested new knee joint lateral projection imaging method, by using a simple support device, could describe joint space as not much different as existing recommended method without some complex process, and could increase convenience of the practician in the process of the imaging.

Osteoarthritis (OA) of the temporomandibular joint (TMJ) is a severe form of temporomandibular disorders (TMDs), presenting gradual breakdown of articular cartilage and subchondral bone by the functional load sustained to exceed the physiologic tolerance of the joint. In such a joint loaded, offensive bioactive materials such as matrix degrading proteins, cytokines, and free radicals increase in concentration to shift the tissue response in the joint to degeneration from regeneration or remodeling. Recently, it has been issued that obesity can play an offensive role in pathogenesis of OA in a metabolic way. Adipokines released by adipose cells are present at higher concentration in the arthritic joint and joints of obese individuals. However, because of conflicting data reported, further scientific study should be performed to elucidate the practical role of adipokines in pathogenesis of TMJ OA. As far as the clinical signs and symptoms of TMJ OA are not much different from those of other forms of TMD and any definitive treatment modality to control directly the bone resorptive activity is not available yet, the treatment of TMJ OA should be directed to reduce the physical load and enhance the physiologic tolerance of the joint by means of conservative treatment such as physical therapy, medication, and occlusal splint therapy for sufficient period and, if needed after that, supplementary surgical procedure such as intra-articular injection, arthrocenthesis, and arthroscopic surgery that have turned out to be effective to control OA signs and symtpoms. Enthusiastic reassurance and motivation for patients to control behaviors for themselves to reduce unnecessary functional load in daily life is very important for the joint to reach to more favorable orthopedic stability of the TMJ more quickly, guaranteeing more successful management TMJ OA.

Purpose: Distal radius fractures in youth are treated conservatively in most cases, but there are some cases of redisplacement in the follow-up period after cast immobilization, even after complete reduction. This study examined the risk factors of redisplacement in reduced unstable distal radius fractures. Materials and Methods: From February 2011 to June 2018, 44 unstable distal radius fractures were managed with a closed reduction and cast immobilization. The patients were aged between 6 and 14 years. The cases of redisplacement were analyzed with the fracture characteristics (fracture obliquity, fracture level ratio, ulnar fracture combined), cast qualities (gap index, cast index, 3 point index, and radius-2nd metacarpal angle) and host factors (age, sex). Results: The mean angulation in the union was 9.2° (0°-32.8°). In the categorical grouping 29 cases were within 10° angulation, and 15 cases were more than 10°. No significant differences in the factors of the cast indices or host factors were noted. The meaningful factor was the fracture level calculated by the relative width of the fracture site divided by the sum of width of diaphysis and epiphysis (p=0.001) and combined ulnar fracture (p=0.019). Conclusion: Unstable distal radius fractures should be treated with more stubborn guidelines lest the fracture loses its anatomical alignment. In particular, in patients with less remodeling power, operative treatment would secure a better result if the fracture occurs in a more proximal location.
