이 연구의 목적은 악관절 내장증 환자에서 관절원판의 형태를 자기공명영상사진으로 평가하고 임상적 증상과의 관계를 알아보고자 하는 것이다. 악관절 내장증의 증상을 가진 90명의 환자에서 169개의 관절을 자기공명영상사진으로 관절원판과 하악과두의 관계를 기준으로 정상군, 정복성 관절원판 변위군, 비정복성 관절원판 변위군으로 분류하고 관절원판의 형태를 5가지로 나누었다. 임상검사는 측두하악관절통과 관절음의 유무를 확인하여 그 상관관계를 알아보았다. 실험 결과에서 측두하악관절통은 각 군에서 관절원판의 형태와는 정상군을 제외하고는 통계적인 유의성이 없었으며, 염증성 삼출액과 유의한 관계를 보였다. 관절음은 정복성 관절원판 변위환자에서 관절원판형태와 통계적으로 유의성을 보였으며, 비정복성 관절원판 변위환자에서도 상당수 관절음이 발생하였음을 알 수 있었다. 이 결과는 측두하악관절의 통증은 관절원판의 형태가 많이 변형될수록 통증이 심해지는 경우가 많았지만, 다른 여러 가지 원인들이 존재할 수 있으며, 관절음은 정복성 관절원판 변위환자에서 관절원판의 변형이 심할수록 관절원판이 정복할 때 발생될 수 있다는 것을 의미한다. 따라서, 임상적인 검사와 더불어 자기공명영상사진으로 정확한 진단을 함으로써 관절원판 변위의 적절한 치료가 행해질수 있으리라 생각된다.

Irreducible knee dislocation is a rare injury and often need an open procedure with ligaments reconstruction. This report describes a case of arthroscopic treatment of a patient with traumatic knee dislocation unable to reduce in a closed method. MRI revealed incarceration of the medial collateral ligament and capsule in the medial compartment. And arthroscopic examination confirmed incarcerated medial capsuloligamentous structures which prevented the knee from reduction. Arthroscopic procedure without ligaments reconstruction was complete when the medial condyle was well visualized and the knee reduced. After 4 weeks of immobilization in extension, range of motion exercise and gradual increases in weight bearing was allowed. At the 3- year follow-up, mild laxity was remained but the patient did not have any discomfort of doing ADL activity and showed full range of motion of the knee.

Aim: Disc displacement without reduction of the temporomandibular joint (TMJ) has been managed by mandibular manipulation to reduce the displaced disc but with a low success rate. The purpose of this study was to determine whether auriculotemporal nerve block anesthesia had an effect on the reduction of the displaced disc and to analyze the factors that influenced the result. Methods: 112 patients were diagnosed with disc displacement without reduction and treated by mandibular manipulation. Disc was recaptured in 35 patients. Among the 77 patients with whom disc recapture had failed, the auriculotemporal nerve was blocked with a local anesthetic in the 49 patients (mean $age \;{\pm}\; SD\; =\; 34.4\;{\pm}\; 15.1$; male 24, female 25) and then mandibular manipulation was performed again. Factors including age, elapsed time from the onset, and opening amount were analyzed in association with disc reduction rate with the auriculotemporal nerve block. Results: Among 49 patients who did not respond to manipulation only, manual reduction with auriculotemporal nerve block anesthesia was successful in 19 patients (38.8%). Maximum unassisted opening amount significantly increased in the 19 patients with successful recapture of the disc ($mean \;{\pm}\; SD\; =\; 46.1 \;{\pm}\; 4.5\; mm$), in contrast to the limited opening amount of the 49 patients before local anesthesia of the auriculotemporal nerve ($mean \;{\pm}\; SD\; =\; 25.7 \;{\pm}\; 6.0\; mm$). Age, elapsed time after the onset, and preoperative opening amount were not associated with the reduction rate. Conclusion: The results of this study suggest that auriculotemporal nerve block anesthesia increases the reduction rate of the disc displacement without reduction of the TMJ when combined with mandibular manipulation, and such anesthesia should be applied at the first stage of manual treatment of disc displacement without reduction.

The muscular button holing of vastus medialis is a very rare case of irreducible knee dislocations, and rapid reduction of this can diminish the complications which delayed reduction accompanies. We diagnosed a patient who appeared posterolateral dislocation of the knee and protrusion of the medial femoral condyle with MRI grossly. That was reduced by open arthrotomy, followed the reconstruction of both cruciate ligaments and repair of medial collateral ligament. Patient didn't show joint instability except minor posterior sagging and had full range of motion postoperatively after 10 months.

Disc dislocation without reduction, as known as closed lock, is a clinical condition in which the disc is dislocated from the condyle and does not return to normal position during condylar movement When the condition of disc dislocation without reduction is acute, the initial therapy should include an attempt to reduce or recapture the disc by manual manipulation. When patients report a history of being locked for 1 week or less, manual manipulation is usually successful. In patients with a longer history, success rate tends to decrease rapidly. If the disc has been successfully recaptured, placing an anterior positioning appliance is recommended to prevent clenching on the posterior teeth, which would likely redislocated the disc. But it is hard to make an appliance immediately in the clinic because it takes too much time. And making an appliance using self-curing acrylic resin is not very popular because of its discomfort by odor and working time. Also, if the patient has resin allergy or is under orthodontic treatment, or if it is impossible to control behavior of the patient, it has been restricted to make an appliance immediately. Therefore, to supplement this disadvantages, we tried to confirm about successful short term use of temporary anterior positioning splint made by using putty impression material after manual manipulation in this study.

An 11 year-old intact female Yorkshire Terrier weighing 3.5 kg was presented with the complain of having a perineal mass, fecal incontinence and tenesmus. Physical examination revealed reducible bilateral ventral perineal mass, enlarged mammary gland and vaginal discharge. Bilateral ventral perineal hernia (BVPH) and pyometra were diagnosed based on the clinical and radiographic findings. Ovariohysterectomy was performed after general anaesthesia to treat pyometra. The BVPH was repaired by herniorrhaphy with semitendinosus muscle transposition along with colopexy and cystopexy. The postoperative radiographs and CT revealed a good correction of the BVPH. The patient showed good activity after 10 days and no complications were observed during a one year follow up period. BVPH can be successfully surgically managed by herniorrhaphy with semitendinosus muscle transposition along with cystopexy and colopexy in the dog.

Conquering top and climbing was a major visiting purpose of Nogodan in the Chrisan National Park. The visitors prefered climbing as visiting times increased. 37 percents of the visitors did not know Mt. Chiri as a national park and 78 percents of the visitors did not understand Mt. Chiri as a observing nature area. No of visitors to Chirisan National Park and Nogodan increased each by 2.2 times (2.6 millions) and by 7 times (260 thousands), respectively after construction of the Sungsamjae access road in 1988.

The purpose of this study is to evaluate the effect of Dulegil in Bukhansan National Park in dispersing peak climbing hikers, characterize each section of Dulegil and suggest ideas of improvement. This study was conducted based on the survey completed by visitors in all 21 sections of Dulegil. After the construction of Dulegil, the number of visit to Dulegil grew and it was analyzed that Dulegil attracted new visitors given that the rate of young people(aged 19~30) who visited for the first time was quite high. Regarding the frequency of peak climbing, 7.6% of the respondents said "decreased" and 46.2% said "increased", showing that Dulegil's effect to disperse peak climbing hikers is nominal. Seven qualities were evaluated regarding Dulegil's level of satisfaction. Out of those seven, the quality of recreational place and taking a walk achieved high scores of 3.74 and 3.61 respectively. The quality of culture and history scored the lowest with 3.09. The analysis on the characteristic of each section of Dulegil, reason of visit, and the visitors' level of satisfaction showed that Dulegil is now regarded as a place where they can improve their health through light exercise and walking. In addition, a positive effect can be expected for a long time since there are different ways of utilizing the resources of the National Park, such as getting in touch with nature, preserving ecology, learning history and enjoying beautiful landscapes. If infrastructure and programs specific to each section of Dulegil were improved in a long-term perspective, it would be effective to encourage peak climbers and enjoy the lower parts of the mountain.
