Purpose: To evaluate the short-term clinical outcomes of total ankle arthroplasty for the post-traumatic osteoarthritis. Materials and Methods: Fourteen patients who had undergone total ankle arthroplasty from February 2005 to June 2006 were reviewed. Eleven patients were male and three patients were female. The mean age was 52.8 years (range, 33 to 69 years). The mean follow-up duration was 15.9 months (range, 12 to 24 months). Primary injuries were pilon fractures in eight cases, malleolar fractures in three, ankle syndesmotic injury in one, talus fracture and dislocation in one, and distal tibial physeal injury in one. Visual analogue scale (VAS), Range of motion (ROM), American Orthopaedic Foot and Ankle Society (AOFAS) score and complications were evaluated. Results: The mean VAS improved from 8.6 preoperatively to 2.6 at last follow-up. The mean ROM improved from 24.6 degrees preoperatively to 33.1 degrees postoperatively. The mean AOFAS score improved from 44.5 points preoperatively to 75.1 points postoperatively. Radiographically, all components were stable, but there were component malpositions in two cases, including one varus malposition of tibial component and one increased anterior translation of talar component. Complications were deep infection in one case, intraoperative malleolar fracture in three, marginal wound necrosis in two, and heterotopic ossification in one. One prosthesis was revised because of deep infection. Conclusion: Total ankle arthroplasty for the post-traumatic osteoarthritis is believed to be an useful method for preservation of the motion, relief of the pain and high satisfaction of patients in short-term results.

The purpose of this study was to analyze the mid to long-term clinical and radiological outcome of vascularized pronator quadratus-wrapped radial bone flap arthroplasty for symptomatic advanced $Kienb{\ddot{o}}ck's$ disease. Between 1982 and 2000, 41 cases of advanced $Kienb{\ddot{o}}ck's$ disease were treated with vascularized pronator quadratus wrapped radial bone flap arthroplasty. There were 17 men and 24 women, with a mean age of 39 years at the time of operation. According to Lichtman's classification, there were 13 stage IIIb and 28 stage IV patients. The duration of follow-up averaged 6.1 ($3{\sim}22$) years. We assessed the clinical outcome by subjective pain and active range of motion of the wrist, and evaluated the radiologic outcome by using carpal height ratio and radioscaphoid angle. Postoperatively, all patient reported an improvement in their symptoms. The mean active extension and flexion were improved by $9^{\circ}$ and $6^{\circ}$, respectively (p<0.05). The carpal height ratio was decreased from a mean of 0.52 to 0.48, and the radioscahpoid angle was increased from a mean of $61^{\circ}$ to $66^{\circ}$, but the differences were not significant statistically. Vascularized pronator quadratus-wrapped radial bone flap arthroplasty improves the wrist motion and may prevent serious carpal collapse in advanced $Kienb{\ddot{o}}ck's$ Disease.

While working in an industrial environment which requires extended periods of upright posture; workers tend to develop muscle fatigue due to the constant load on lower-limb muscles. In addition, when working while bending knees; muscle fatigue of lower back and hamstrings is increased due to the abnormal posture. This can lead to damage of muscles, induce musculoskeletal disorders, and reduce long-term working efficiency. Recent medical studies have shown that long-term working in an upright posture can induce musculoskeletal disorders such as foot fatigue, edema, pain and varicose veins. Likewise, medical and rehabilitation expenses have grown due to the increase in musculoskeletal conditions suffered by workers. For this problem, we aim to develop a device that can reduce the physical fatigue on the lower limbs by supporting the weight of workers during the extended periods of upright and bending postures in the industrial environments. In this paper, we have designed and manufactured a wearable weight support system; with a user intention algorithm that the users can maintain various postures. For validation of the developed system, we measured the muscle activity of the users wearing the system with EMG sensors.

Objectives : Although interest in preventive medicine has increased recently, "Mibyeong", the preventive concept of Korean medicine, is still unfamiliar to the general public. Therefore, this study aims to investigate the concept of Mibyeong and users used on the Internet. Methods : Naver (www.naver.com), which has the highest ranking in terms of market share, number of visitors, search time share, and community category share, has been selected as a search target and jisik-iN Q&A and posts of cafe about Mibyeong were searched for recently approximately 6 years. Results : 105 cases of Jisik-iN Q&A and 283 cases of cafe posts were searched. Overall, the number of Jisik-iN Q&A and cafe posts's Mibyeong term usage was the highest in 2013. In the Internet user category, Mibyeong Term was used most commonly in the Jisik-iN Q&A by Korean medicine related medical personnel (29 cases, 28%) and in the cafe other health-related workers (87cases, 31%). In Mibyeong related cafe classification, Information Exchange (220 cases, 77%) was the most frequent and besides 39 cases (14%) used in Operation of Medical Institutions. And the concept of Mibyeong was often used as symptom-based rather than diagnostic test or disease (Cafe posts 52%, Jisik-iN Q&A 70%), in particular, topic of Mibyeong related Jisik-iN Q&A was used in the order of pain (31 cases, 16%), cancer (17 cases, 9%), fatigue (11 cases, 6%). Conclusions : This study has significance as basic research data of general Internet user group and can be used as fundamental data for awareness promotion, publicity and necessity of Mibyeong.

The forty patients with carcirLoma of the esophagus or cardia seen at National Medical Center between November 1983 and April 1994 underwent surgical exploration. The esophagogastrectomy was carried out in 29 of 40 patients, one case through right thoracotomy, the others through left thoracotomy. Two patients underwent colon bypass surgeries due to upper esophageal cancer Transhiatal esop agectomy was performed In one case. Feeding gastrostomy or feeding jejunostomy were performed in 8 patients due to the advanced stage or malnutrition. In this report, we evaluated the long-term results in the 28 patients who underwent esophagogastrectomy for palliation through the left thoracotomy. There were 25 men(89%) and 3 women(11 %), and the mean age was 58.65$\pm$7.15 years(range, 46 to 73 years). The most frequent preoperative symptoms included dysphagia (22), weight loss (15), chest pain (6), vomiting (1), and hoarsness (1). Twenty-three patients had sqamous cell cancers of mid-and lower esophagus and five adenocarcionomas of cardia. One patient died in the hospital within 30 days of the op- eration for a hospital mortality rate of ).7%, Cause of death was sepsis due to anastomotic leakage. There were five additional complications in five patients; acute respiratory distress syndrome (1), post-op- erative bleeding (1), diaphragmatic hernia (1), acute renal failure (1) and late raft stenosis (1). The one year, 1틴o years, and three years acturial survival rate were 75.6$\pm$9.5%, 43.2$\pm$ 11.6%, 21.6: 10.5$\circledcirc$ re- spectively. The average survival was 21.8 months. The data from this study suggest that esophagogastrectomy through the left thoracotomy can achieve resonable long-term palliation for carci- noma of the esophagus. The operation can be performed with a low operative mortality and few serious postoperative complications.

Whenever endodontic therapy is performed on mandibular posterior teeth, damage to the inferior alveolar nerve or any of its branches is possible. Acute periapical infection in mandibular posterior teeth may also sometimes disturb the normal functioning of the inferior alveolar nerve. The most common clinical manifestation of these insults is the paresthesia of the inferior alveolar nerve or mental nerve paresthesia. Paresthesia usually manifests as burning, prickling, tingling, numbness, itching or any deviation from normal sensation. Altered sensation and pain in the involved areas may interfere with speaking, eating, drinking, shaving, tooth brushing and other events of social interaction which will have a disturbing impact on the patient. Paresthesia can be short term, long term or even permanent. The duration of the paresthesia depends upon the extent of the nerve damage or persistence of the etiology. Permanent paresthesia is the result of nerve trunk laceration or actual total nerve damage. Paresthesia must be treated as soon as diagnosed to have better treatment outcomes. The present paper describes a case of mental nerve paresthesia arising after the start of the endodontic therapy in left mandibular first molar which was managed successfully by conservative treatment.

Purpose: The purpose of this study was to evaluate the clinical outcome of a modified Kidner procedure using a suture bridge technique in symptomatic type II accessory navicular. Materials and Methods: Between January 2013 and December 2014, a total of 35 cases with symptomatic type II accessory navicular were treated with a modified Kidner procedure using the suture bridge technique. The patients were evaluated preoperatively, 3 months after surgery, and at the latest follow-up (at least six months postoperatively) clinically via the American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score, visual analogue scale (VAS), and the self-subjective satisfaction score. Results: The mean AOFAS midfoot score demonstrated significant improvement from a mean of 45.3 preoperatively to a mean of 89.2 at 3 months after surgery. At the latest follow-up, the mean AOFAS midfoot score was 92.6 (p<0.001). The mean VAS also improved significantly, decreasing from 6.7 out of 10 preoperatively to 1.8 at 3 months after surgery. At the latest follow-up, the VAS was 1.2 (p<0.001). The mean time of a single-limb heel raise was 4.6 months postoperatively and the self-subjective satisfaction score was 1.4 out of 4 at the latest follow-up. Conclusion: The short-term surgical results of the modified Kidner procedure with a suture bridge technique for symptomatic type II accessory navicular were good to excellent in terms of pain, functional and clinical assessments. In conclusion, the modified Kidner procedure with the suture bridge technique is a reasonable treatment option for symptomatic type II accessory navicular.

Purpose: The purpose of this study was to examine the association between utilization of home care services under the national long-term care insurance system and family caregiver distress. Methods: A secondary data analysis was conducted in this study using data collected in 2011 and 2012 from the Korean version of International Resident Assessment Instrument (interRAI) Home Care assessment system. The study sample included 228 clients receiving community based home care and their family caregivers in Korea. Descriptive statistics, $x^2$ test, t-test, and Heckman selection model analysis were conducted using SAS 9.3. Results: Presence of family caregiver distress was significantly associated with days of nurse visits (${\beta}$=-.89, p=<.001) and home helper visits (${\beta}$=-.53, p=.014). Level of caregiver distress was also significantly associated with days of nurse visits (${\beta}$=-.66, p=.028). Other factors which were significantly associated with caregiver distress were depression, cognitive function, inadequate pain control, social support for older adult, and caregiver relationship to the older adult. Conclusion: The results of this study show that visiting nurse service and appropriate support programs for Older Adults and family caregivers experiencing caregiver distress should be developed and provided to families based on the health care needs of older adults and their family caregivers for effective and sustainable home care.

This is case report of open reduction of condylar fractures with or without discal injury. Many articles described open reduction and internal fixation of condylar fractures emphasize the method of bony reduction and fixation without mention of the position of the disc. So we like to present our cases of open reduction of condylar fractures in conjunction with reconstruction of the disc and associated structures. The pupose of this presentation is to emphasize several well - established principles of trauma management and management of temporomandibular joint injuries, such as 1) in situations of traumatic injury, anatomic restoration is the goal of treatment and, 2) anatomic alignment of the TMJ disc over the condyle is preferable to disc subluxation because the latter may lead to chronic pain, limitation of opening and degenerative arthritis. Although our case is small with short term follow up, we believe that open reduction and internal fixation of condylar fractures in conjunction with disc repair is a biologically sound approach to those fractures indicated for open surgery. Long term follow up will allow better judge the validity of this treatment approach to us.
