A 69-year-old male pateint was admitted for discomfort on right temporomandibular joint during opening, closing and chewing that started few months ago. The patient had no special medical history except for lung tuberculosis approximately 30 years ago and nothing specific appeared on a physical exam taken 2 months ago. Clinical tests show that mouth opening of 53mm which was normal and no joint sound, deviation, pain during opening. But tenderness to palpation on Rt masseter muscle and pain existed on Rt temporomandibular joint during loading test on the right joint. No pain existed during resistance test and protrusion and range of lateral movement was normal. Rt temporomandibular joint was not swollen and no palpable mass was observed. No previous trauma history to the face existed. On X-ray calcific material existed in the joint cavity and on CT image, approximately 2mm sized calcific material appeared on the Rt temporomandibular joint but no change in bone appeared on the condyle nor the temporal bone. The patient was diagnosed as loose body, and the symptoms were relived after 2 physical therapies and is under regular check ups. The purpose of this case is to review disease that cause loose bodies.

This study is descriptive research clarifying the relations between physical inconvenience, social aptitude and sense of satisfaction In life of the chronic arthritis patients. This research has been conducted from 115 patients by structured self-reporting questionnaires and direct interview of the adult patients over the age of 16 years old who had been under treatment in 3 University hospitals in Seoul from Oct. 4, 1996 through Oct. 24, 1996 for 20 days. The collected materials have been under t-test and F-test(ANOVA) per variables after computerizing using SPSS package and the correlation between various causes was conducted by pearson's correlation coefficient method. The results are as the follows : 1) Generally the age of starling the disease was 40-60 with 91 in female(79.0%) and male 88(76.5%), the persons who had the religion showed the high rate of being taken ill and the persons with over high school education have fallen ill by 46.1%. The monthly income has shown that 77.5% was over 1,000,000won or over, the periods of the disease in average was 4 years 3 months showing it was the chronic disease, the degree of recognizing the disease was 19.0%, spouse and children were most concerned about their disease and the part of Joint attacked was knee(73.0%), wrist(43.5%) and others which showed that they have been very inconvenient in daily life. 2) The variables affecting to physical inconvenience were by age (F=9.06, p=.000), education level(F=7.14, p=000), economic standards (F=2.18, p=.05), the period of disease(F=3.09, p=.03), hospitalized or not(F=3.23, p=.002), showing such correlations. 3) The variables affecting to the social adaptation were by age (F=3.47, p=.018), education level(F=4.98, p=.001), periods of taken ill (F=419, p:.007), hospitalized or not (F=3.23, p=.004) and the operation or not (F=1.30, p=.028) showing such correlations. 4) The variables affecting to life satisfaction were by sex(t=2.08, p=.045), economic status(F=3.15, p=.01) being able to explain statistically. Through the above correlations, they are required to receive self-management education positively to elevate the effect of rehabilitation treatment and effective nursing arbitration and also they required to be reduced physical inconvenience at the early stage and be helped to be able to lead the quality life in satisfaction by elevating the diverse adaptation to the society by correcting the transformed joint.

Arthrosis of the temporomandibular joint is defined as a disease of a joint with chief complaint of pain, clicking, limited jaw movements. Generally, most patients with the temporomandibular arthrosis can be treated conservatively with muscle relaxation therapy combined with mandibular repositioning prostheses, followed by occlusal equilibration, restorative dentistry and/or orthodontics, and many other forms of treatment. In case prior nonsurgical treatment proved to be ineffective or the disease is chronic and severe, surgical operation is recommended. For patients with arthrosis of the temporomandibular joint, only discectomy as therapeutic method of the surgical treatment should not be applied and the removed articular disc of the temporomandibular joint should be replaced. Allograft such as Proplast-Teflon, Silastic, etc have been used as replacements of removed articular disc. However, these allograft materials have caused complications such as inflammatory changes, foreign body reactions. As a result, a replacement material which is autogenous, space occupying, easy to harvest and less inflammatory change has been developed. Auricular cartilage with perichondrium satisfies many of these requirements. The apparent advantages of autogenous auricular cartilage as an interpositional graft after a discectomy are as follows, (1) the form of the external ear corresponds to joint morphology, (2) a graft of adequate size can be harvested, (3) the form of the external ear remains unchanged after surgery, (4) the graft can be obtained adjacent to the surgical site, (5) biologically acceptable material is used, (6) the additional expense of allogenic graft is avoided. Because we considered autogenous auricular cartilage as a good replacement material, removed articular disc has been replaced with fresh autogenous auricular cartilage in the case of three patients. The result of the treatment is favorable, and the cases being presented here.

Optical Coherence Tomography (OCT) is an important noninvasive medical imaging technique that can reveal subsurface structures of biological tissue. OCT has demonstrated a good correlation with histology in sufficient resolution to identify morphological changes in articular cartilage to differentiate normal through progressive stages of degenerative joint disease. Current OCT systems provide individual cross-sectional images that are representative of the tissue directly under the scanning beam, but they may not fully demonstrate the degree of degeneration occurring within a region of a joint surface. For a full understanding of the nature and degree of cartilage degeneration within a joint, multiple OCT images must be obtained and an overall assessment of the joint surmised from multiple individual images. This study presents frequency domain three-dimensional (3-D) OCT imaging of degenerative joint cartilage extracted from bovine knees. The 3-D OCT imaging of articular cartilage enables the assembly of 126 individual, adjacent, rapid scanned OCT images into a full 3-D image representation of the tissue scanned, or these may be viewed in a progression of successive individual two-dimensional (2-D) OCT images arranged in 3-D orientation. A fiber-based frequency domain OCT system that provides cross-sectional images was used to acquire 126 successive adjacent images for a sample volume of $6{\times}3.2{\times}2.5\;mm^3$. The axial resolution was $8\;{\mu}m$ in air. The 3-D OCT was able to demonstrate surface topography and subsurface disruption of articular cartilage consistent with the gross image as well as with histological cross-sections of the specimen. The 3-D OCT volumetric imaging of articular cartilage provides an enhanced appreciation and better understanding of regional degenerative joint disease than may be realized by individual 2-D OCT sectional images.

The paper reviews various classifications and surgical techniques for the treatment of temporomandibular joint ankylosis. PubMed, EBSCO, Web of Science, and Google Scholar were searched using a combination of keywords. Articles related to classification, resection-reconstruction of the temporomandibular joint, and management of airway obstruction were considered and categorized based on the objectives. Seventy-nine articles were selected, which included randomized clinical trials, non-randomized controlled cohort studies, and case series. Though several classifications exist, most classifications are centered on the radiographic extent of the ankylotic mass and do not include the clinical and functional parameters. Hence there is a need for a comprehensive staging system that takes into consideration the age of the patient, severity of the disease, clinical, functional, and radiographic findings. Staging the disease will help the clinician to adopt a holistic approach in treating these patients. Interpositional arthroplasty (IA) results in better maximal incisal opening compared with gap arthroplasty, with no significant difference in recurrent rates. Distraction osteogenesis (DO) is emerging as a popular technique for the restoration of symmetry and function as well as for relieving airway obstruction. IA, with a costochondral graft, is recommended in growing patients and may be combined with or preceded by DO in cases of severe airway obstruction. Alloplastic total joint replacement combined with fat grafts and simultaneous osteotomy procedures are gaining popularity. A custom-made total joint prosthesis using CAD/CAM can efficiently overcome the shortcomings of stock prostheses.

목적: 전방십자인대 재건술의 수가 증가하면서, 재건술의 실패로 인한 재재건술의 빈도 또한 증가하고 있다. 따라서 저자는 전방십자인대 재건술 후 발생한 이식건 실패의 원인 및 전방십자인대 재재건술 후의 임상적 결과를 분석하였다. 대상 및 방법: 1998년 2월부터 2010년 7월까지 전방십자인대 재건술 실패에 대하여 전방십자인대 재재건술을 시술받은 후 최소 12개월 이상 추시가 가능하였던 36예를 대상으로 하였다. 재건술 후 재재건술까지의 평균기간은 60(5~334)개월이었으며, 처음 전방십자인대 재건술을 시술 시 23예(63.9%)에서 동종 이식건을, 13예(36.1%)에서 자가 이식건을 사용하였다. 전방십자인대 재건술 실패의 주증상으로 불안정성이 가장 많았으며, 전방십자인대 재건술을 한번 시행 받았던 경우가 35예(97.5%), 두 번 시행 받았던 경우가 1예(2.5%)였다. 임상적 결과는 Lysholm 슬관절 점수, Tegner activity 점수를 이용하여 평가하였으며, 안정성은 Lachman 및 pivot shift 검사와 Telos device를 이용하여 평가하였다. 결과: 환자의 평균 추시 기간은 21(12~40)개월이었으며, 전방십자인대 재건술의 실패원인으로는 외상이 19예(52.8%)로 가장 많았고, 대퇴 터널의 부정위치가 13예(36.1%), 경골부 터널의 부정위치가 1예(2.8%), 골융합의 실패 3예(8.4%)로 나타났다. 전방십자인대 재재건술을 시행할 시 34예(94%)에서 동종이식건을, 2예(6%)에서 자가 이식건을 사용하였으며, 21예에서 반월상 연골판 손상이 동반되었다(내측 반월상 연골판 손상 14예, 외측 반월상 연골판 손상 7예). Lysholm 슬관절 점수는 술전 66.5점에서 술후 최종 추시시 92점으로 호전되었다(p<0.01). 환자의 대부분은 수술 결과에 만족(92%)하고 있었다. Tegner activity 점수는 술전 2.0점에서 술후 6.2점으로 호전되었다(p<0.01). Lachman 및 pivot shift 검사에서 33예, 30예가 Gr I 이하로 호전되었으며, Telos device를 이용한 안정성 검사에서는 양측 차이 정도는 술전 평균 15.5 mm에서 술후 최종 추시시 4.5 mm로 의미있게 호전되었다(p<0.01). 환자의 대부분은 수술 결과에 만족(92%)하고 있었다. 결론: 전방십자인대 재 재건술은 1년 이상 추시 결과 약간의 전방 불안정성이 존재하였으나, 임상적 결과 및 환자의 주관적 만족도에 있어서는 우수한 결과를 보였다.

Objective: A comparison of American Joint Committee on Cancer (AJCC) 1988 and 1997 nasopharyngeal carcinoma (NPC) classifications was made in terms of patient distribution and efficacy in predicting prognosis. Materials and Methods: Between Jan. 1981 and Dec. 1998, 60 cases of node negative nasopharyngeal carcinoma were retrospectively reviewed. The extent of disease each patients restaged according to the 4th and 5th AJCC system and Ho system, respectively. Results: The overall and disease free 5-year survival rates were 61.1% and 62.6%, respectively. Among T classifications of 4th AJCC, 5th AJCC and Ho staging system were not observed significantly different in disease-free survival rates, respectively. Conclusion: We observed a better patient distribution with AJCC 1997 comparing to AJCC 1988. The new classification also attained better statistical significances among stages in the overall survival and disease free survival rates was needed.
