회전근 개 질환의 병리기전의 연구과정은 과거에 형태학, 거시적 해부학 또는 방사선학적 연구를 통해 충돌 증후군에 대한 연구에 집중되었으나 그간의 병리조직학 및 생역학의 발전에 힘입어 좀 더 근본적인 원인에 대한 접근이 가능하게 되어 다양한 요인에 의해 복합적인 기전을 통해 발생함이 밝혀지고 있다. 그러나 아직 이와 같은 성과를 바탕으로 임상적으로 적절한 진단, 치료, 재활 및 예방에 대한 명확한 해답을 제시하기에는 부족함이 있으며 향후 건 내의 퇴행성 변화에 대한 분자 생물학적인 접근과 생체 내와 같은 조건에서의 역동성을 재현할 수 있는 견관절 모델의 개발을 통한 더욱 향상된 생역학적 연구가 필요할 것으로 생각된다.

This study attempted to analyze the difference in exercise-related factors according to the presence or absence of metabolic syndrome in middle-aged adults. Among the raw data of the 7th National Health and Nutrition Survey (2016-2018), 4,518 out of 5,421 middle-aged adults, excluding 903 who had insufficient responses, were selected as the final analysis targets. As a result of the study, the lower the level of education, the lower the subjective health status, and the less physical activity, the more significantly related to metabolic syndrome. According to the results of this study, active physical activity is necessary to prevent and manage metabolic syndrome in middle-aged adults, and more diverse factor analysis and multi-faceted research are needed in the future.

Purpose : The purpose of this study was to evaluate clinical efficacy of the arthroscopic anterior acromioplasty for the treatment of chronic impingement syndrome of the shoulder. Materials and Methods : Between July 1995 and December 1997, twenty seven consecutive shoulders of 26 patients with chronic impingement syndrome of the shoulder were treated by arthroscopic anterior acromioplasty. The patients who had severe osteoarthritis of the shoulder full thickness tear of the rotator cuff, and nonoutlet impingement were excluded. The clinical results were evaluated by using UCLA shoulder rating scale. The average follow-up was 2years 3months(range, 1year 7months to 3years 1 11months). Results : Twenty three patients$(85.2\%)$ were rated as excellent or good results, while four patients$(14.8\%)$ were fair. Twenty six cases$(96.3\%)$ were satisfied with the results of the operations, while one case$(3.7\%)$, who had Parkinsonian syndrome, ossification of posterior longitudinal ligament(OPLL) of the cervical spine, and spinal stenosis of the 5th and 6th cervical spine was not satisfied. Conclusion : Arthroscopic anterior acromioplasty was an effective treatment method, especially for relief of pain, for the treatment of chronic impingement syndrome of the shoulder. If the patient has the combined lesions in the cervical spine and the shoulder, and systemic lesions, these lesions may influence the results of treatment after operation, and cause the unpredictable results.

Purpose: The morphological study and dynamic stability of the ulnar nerve around the elbow joint was investigated in asymptomatic normal population using ultrasonography. The purpose of this study is to provide fundamental data for ultrasonographic diagnosis of ulnar neuropathy in cubital tunnel syndrome. Materials and Methods: Fifty cases of 25 healthy male volunteers, aged between 20 to 30 years, included in this study. High resolution 7.5 MHz linear probe was used to examine the ulnar nerve in axial and longitudinal views. In a longitudinal view, the course, position and the thickness of nerve were monitored, the diameter of ulnar nerve and dynamic stability at elbow flexion and extension were measured in an axial view at four different points; 1cm proximal to medial epicondyle, behind the medial epicondyle, entrance to Osborne ligament, and 1cm distal to Osborne ligament. Results: The short diameters of ulnar nerve at elbow extension at four anatomic points were 2.66 mm, 2.97 mm, 2.64 mm, and 2.69 mm and the long diameters were 4.61 mm, 4.56 mm, 4.36 mm, and 4.37 mm, which showed no significant change at each point. However, at elbow flexion, the short diameters were changed to 2.72 mm, 2.34 mm, 2.65 mm, and 2.41 mm and the long diameters into 4.49 mm, 5.40 mm, 4.16 mm, and 4.66 mm. At elbow flexion, significant morphologic change was observed in the medial epicondyle area, and the diameter of the ulnar nerve was shortest at the entrance of Osborne ligament both at flexion and extension. In terms of dynamic stability, nine subluxations and seven dislocations were observed. Conclusion: This study shows dynamic instability and a morphological change of long and short diameters of ulnar nerve at flexion and extension in a normal person, which should be considered in the ultrasonographic diagnosis of ulnar neuropathy.

Repetitive overhead throwing exerts significant mechanical stress on the elbow joint. Pitching in baseball, serving in tennis, spiking in volleyball, passing in American football and launching in javelin-throwing can all produce elbow pathology by forceful valgus stress, with medial stretching, lateral compression and posterior impingement. This stress can lead to developmental anatomic changes in the young thrower. Asymptomatic pathology in the shoulder and elbow joint is prevalent and, with overuse, can progress to disabling injury. Joint injury occurs as a result of the body's inability to properly coordinate motion segments during the pitching delivery, leading to further structural damage. The implications of acute and overuse injuries and the possibility of permanent damage should be understood by parents, coaches and the athletes. Proper understanding of the intrinsic and extrinsic risk factors that could lead to elbow injuries is thus required. Measures to prevent elbow injuries should include proper coaching, warm-up, medical expertise and protective gear. Injury prevention and rehabilitation should center on optimizing pitching mechanics, core strength, scapular control, and joint range of motion.

The Buford complex is unusual variant of the glenohumeral joint. This complex is distinguished by a cord-like middle glenohumeral ligament that oriented directly form the superior labrum at the base of the biceps tendon and crosses the subscapularis tendon to insert on the humerus. There is no anterior-superior labral tissue present between this attachment and the mid-glenoid notch. This anatomical variation may lead the surgeon to confuse this complex with a sublabral hole, pathologic labral detachment, Bankart lesion or SLAP lesion. We report a case of Buford complex which was found incidentally during the operation of impingement syndrome with stiffness and treated with subacromial decompression only.

This study aimed to evaluate the correlation between metabolic syndrome and periodontal in the adult Korean population on the basis of the 2009 Korea National Health and Nutrition Examination Survey(NHANES) data. Of 19-year-old or older adult patients suffering from their disease diagnosed as metabolic syndrome, 1,315 subjects whose community periodontal index(CPI) information was fully available were finally analyzed, and the following conclusions were drawn. 1. It was found that of sociodemographic characteristics, age and educational background correlated to the prevalence of periodontal diseases. With increasing age and poorer educational background, the rates of periodontal diseases increased(p<0.001). 2. It was revealed that of general health behaviors, smoking, alcohol drinking and BMI correlated with the prevalence of periodontal diseases. Higher rates of periodontal diseases were shown in the group of patients who were current smokers(p<0.05), had the higher frequency of drinking per week(p<0.001), and had higher BMI(p<0.005). 3. It was ascertained that of oral health behaviors, the history of oral health examination in the previous year, the use of proxabrush or dental floss, and perceived(i.e., subjective) oral health status correlated to the prevalence of periodontal diseases. The higher rates of periodontal diseases were seen in those who had no history of oral health examination in the previous year(p<0.001), had used neither proxabrush nor dental floss(p<0.05), and perceived that their own oral health was poor(p<0.001).

Purpose: Purpose was to explore associations between sleep duration and metabolic syndrome (MS) risks, and to determine factors associated with self-rated health (SRH) of adults with MS compared to other adults. Methods: This is a secondary data analysis based on the Fifth Korea National Health and Nutrition Examination Survey KNHANES V (N=12662). Study instruments included sleep duration, MS risk factors, SRH and health-related quality of life (HRQoL). Results: Mean age of participants was $43.68{\pm}12.26years$. Fifty-eight percent were women, and 18.3% were identified as having MS. Systolic blood pressure (SBP), diastolic blood pressure (DBP), and SRH were significantly different according to sleep duration (p <.05) among all participants. In the non MS group, male gender, younger age (19~30 and 41~50 age brackets) upper income level, sufficient sleep duration, and high density lipoprotein (HDL) were positively associated with SRH, whereas, lower education levels (${\leq}$ middle school), glucose level, and waist circumference were negatively associated with SRH (p <.05). In the MS group, lower income, lower education levels (${\leq}$ middle school), glucose level, and waist circumference were negatively associated with SRH, whereas, having an occupation was positively associated with SRH (p <.05). Conclusion: Results suggest that tailored approaches are required for prevention and control of MS and sleep duration of each individual should be considered rather than applying standardized guidelines. However, as sleep quality was not included in the analysis, further investigations regarding influence of sleep quality on MS and SRH and controlling for other lifestyle and health behavior factors are required.

This study aimed to examine whether there was difference on visual fatigue between active seniors and young people, and to provide a guideline for appropriate computer use time for seniors. Blinking rate, maximal blinking interval, temperature of the ocular surface, visual fatigue questionnare were evaluated. The blinking rate, ocular surface temperature, visual fatigue showed significant change before and after the tasks. There was no difference between the two groups and thus, about 30-minute computer work appeared to be appropriate for seniors.
