Chronic lateral ankle instability occurs in 10% to 20% of individuals after acute ankle sprain. The management of chronic lateral ankle instability is traditionally conservative treatment in the acute phase. On the other hand, surgical intervention is considered if conservative treatment fails and the symptoms are ongoing. This review focuses on the surgical approaches to treatment of chronic lateral ankle instability, including $Brostr{\ddot{o}}m$ surgical techniques, with a review of the traditional procedure and newer techniques.

The purpose of this study was to verify the effectiveness of an integrated nursing curriculum based on simulation with problem-based learning (PBL) by comparing the clinical competence and the self-confidence of newly graduated nurses. A non-equivalent control group post-test design was employed to compare the clinical competence and the self-confidence in the clinical performance examination using standardized patients between 39 newly graduated nurses with the traditional nursing curriculum and 35 with the integrated nursing curriculum. Data analysis involved Fisher's exact test, t-test, Pearson's correlation coefficient, and ANCOVA with the SPSS 19.0 program. The total clinical competence mean score graded by the standardized patients was not different between the two groups. However, the total clinical competence mean score graded by faculty was significantly higher in the integrated curriculum group than the traditional curriculum group. The mean self-confidence score was significantly higher in the integrated curriculum group than the traditional curriculum group. Active teaching-learning strategies including simulation or PBL in the nursing curriculum could benefit for nursing students by inducing favorable clinical competence and self-confidence. Longitudinal follow-up studies based on observation are needed to explore the patient outcomes in addition to the learner outcomes in clinical settings.

The purpose of this study was to investigate the correlation between basic self - confidence and CPR - related factors and to investigate factors affecting CPR intention in nursing college students. Data were collected between January to March, 2018. Using SPSS(ver, 24.0), independent t-test, Pearson's correlation and logistic regression were used for the statistical analysis. Among the variables related to cardiopulmonary resuscitation, there was a high correlation (r = .575~.738). In the case of AED use, there was a low correlation with self-confidence of core nursing skills, CPR confidence, proficiency, and self-efficacy (r = .163~.301). A moderate correlation (r = .415~453) was found between the variables related to core nursing skills and CPR related variabls. Logistic regression analysis showed that CPR Self-efficacy (OR=1.22, 95% CI: 1.07~1.38), and AED application Competency (OR=1.72, 95% CI: 1.09~2.75) are effect factors. Since there is a correlation with AED, which is the main tool in CPR, it is necessary to include not only the self - efficacy but also the use of AED which is closely related to CPR in the actual situation as an essential element of education.

Purpose: The purpose of this study was to introduce a new surgical technique and to evaluate the preliminary results after operative treatment with using TightRope$^{(R)}$ for treating acute acromioclavicular joint dislocation. Material and Methods: We studies 10 patients who were followed up for more than 6 months after operative treatment with using an TightRope$^{(R)}$. A longitudinal incision approximately 4cm in length was made from 1cm medial to the acromioclavicular joint to the coracoid process, and then coracocalvicular ligament augmentation using TightRope$^{(R)}$ was done after splitting the deltoid. For postoperative stability, two 1.6 mm Kirschner wires were inserted temporarily across the acromioclavicular joint in all cases. The radiologic results on the serial plain radiographs and the clinical results according to the UCLA score were analyzed. Results: Radiologically, 7 cases showed anatomical reduction, 2 cases showed a slightly loss of reduction and 1 case showed partial loss of reduction. Clinically, 6 cases were excellent, 3 cases were good and 1 case was fair. Conclusion: Coracoclavicular ligament augmentation using TightRope$^{(R)}$ for treating acute acromioclavicular joint dislocation is a minimally invasive, safe procedure that provides satisfactory radiologic and clinical preliminary results. Yet the long-term results have to be analyzed to determine the final results of this procedure.

We introduce arthroscopic Bankart repair technique using antegrade suture passer that can effectively restore detached anteroinferior capsulolabral complex for shoulder anterior instability. After diagnostic arthroscopy is performed using posterior, anteroinferior and anterosuperior portals, we confirm Bankart lesion and perform debridement and decortications of anteroinferior glenoid edge and neck. Suture anchor is inserted through anteroinferior portal at 2 mm medial side of glenoid edge (4:30 direction). Scorpion$^{TM}$ loaded suture is directly advanced to detached and retracted anteroinferior capsulolabral complex and the suture is passed at 10~15 mm medial side of detached anteroinferior capsulolabral complex (5:30 direction). The suture is retrieved by Scorpion's hook and then is tied using samsung medical center (SMC) sliding knot technique. Then suture anchors are serially inserted (2:30, 3:30) and capsulolabral complex repair is performed using suture hook and suttle-relay technique. This technique that can obtain anatomical restoration of anteroinferior glenohumeral ligament with proper tension is useful technique to reduce postoperative recurrence and makes it possible for less experienced surgeons.

Purpose: Inevitably, Maxillary structural defect follows maxillary cancer extirpation. Maxillary reconstruction is over every surgeon's head. Every physician tried to overcome limited donor site of craniofacial defect. We considered to suggest optimal method of inferior orbital wall defect in functional point as well as esthetic point. Methods: We performed wide excision of maxilla and vascularized partial thickness calvarial bone flap to reconstruct the defect from cancer extirpation in three cases. We select ipsilateral superficial temporal artery, vein and outer cortex of parietal bone flap as donor. And we applied bone flap as inferior orbital wall structure. The bony surface was wrapped with fascia to prevent direct contact between orbital contents and rough bony flap surface. Computed tomography image was checked during follolw up period. Results: We can observe these patients for over two years. In all three cases, We can get fair inferior orbital wall structure. Even though they got radiation therapy, there was no limitation of extraocular movements, no diplopia. no enophthalmos. Also there was minimal donor site morbidity. Conclusion: We suggest vascularized calvarial bone flap is practically excellent strategy for inferior orbital wall reconstruction.

Background: A composite valve graft replacement has been used for a variety of aortic root diseases. The aim of this study was to evaluate the mid-term results of this technique. Material and Method: We conducted a retrospective analysis of aortic root composite valve graft replacements in 39 patients and these procedures were done at our institution between 1992 and 2009. The mean age of the patients was $49.2{\pm}16.4$ years. The mean follow-up was $64.2{\pm}53.4$ months (maximum: 176 months). Result: There were 4 hospital deaths (8.6%) due to emergency aortic dissection and 4 late deaths owing to several causes. The causes of late death were 2 ruptures of a remnant aneurysm, 1 subdural hemorrhage and 1 paravalvular leakage. The calculated survival rate was 93.5%, 85.0% and 85.0% at 1, 5 and 10 years, respectively. There were 3 cerebrovascular accidents during the follow up period. The rate of freedom from cerebrovascular accidents was 97.0%, 92.0% and 80.0% at 1, 5 and 10 years, respectively. All of these brain accidents were hemorrhage-related complications. Conclusion: A composite valve graft replacement of the aortic root was associated with favorable results. So, this technique seems to be a good method to treat various aortic root diseases.

This study aimed to evaluate the courses of pediatric dentistry based on correlation analysis between scores of objective structured clinical examination (OSCE) and related subjects for 79 fourth-year students. The score of theory were related to preclinical (r = 0.449, p = 0.000) and clerkship (r = 0.437, p = 0.000) each, but the scores of clerkship were not related to OSCE. To make the students skillful for clerkship, more professor's firsthand teaching on treating patients and adequate numbers of clinical professors are required. Patients who come to the university dental hospital prefer to be treated by professors rather than students. In these circumstances, educational conditions should be arranged by ensuring the number of professors for teaching students to improve their clinical competence through direct instruction and feedback to students. In addition, pragmatic improvement plans, which allow continuous education and evaluation about basic techniques to be examined in the clinical practice course, should be compromised with the more concrete evaluation of the curriculum in order to evaluate theoretical knowledge and technical trainings to be well exercised and deepened in the practical clinical field.

Purpose: To evaluate the clinical stability and function after one-stage revision anterior cruciate ligament (ACL) reconstruction using fresh-frozen Achilles tendon allograft Materials and Methods: Thirteen patients who underwent one-stage revision ACL reconstruction using Achilles tendon allograft could be evaluated. The average time from primary procedure to revision surgery was 61.8 months. The mean follow-up period was 38.4 months. The bone defects of pre-constructed femoral and tibial tunnels were filled with calcaneal bone attached to Achilles tendon and the new femoral and tibial tunnels were created. Evaluations included the causes of failure of primary ACL reconstruction, Lysholm knee score, Lachman test, pivot shift test and KT-1000 arthrometer measurement. Results: The most common causes of failure of ACL reconstruction were poor surgical techniques in 10 cases (76.9%). Ten patients (76.9%) were good or excellent on the Lysholm score. Twelve patients (92.3%) had negative or 1+firm end Lachman test. Eleven patients (84.6%) had negative pivot shift test. Nine patients (69.2%) had less than 3 mm difference of manual maximum by KT-1000 arthrometer. Conclusion: One-stage revision ACL reconstruction with fresh-frozen Achilles tendon allograft, creating new tunnels after filling bone defects, resulted in a reliable and predictable outcome in terms of stability.
