It has been known that the ankle arthrodesis is a common surgical procedure for treating the ankle arthrosis and deformity that do not respond to the non-operative treatment. To date, various surgical techniques for the ankle arthrodesis have been reported. Clinical and biomechanical trials have shown that the rigid internal fixation leads the increased rate of the union. The ankle arthrodesis may be complicated with the nonunion, delayed union, malunion, and infection. In cases of the Charcot joint of the ankle in diabetic patients, however, arthrodesis could reduce the disadvantage of the nonoperative treatment, such as the loss of the reduction, progressive collapse, multiple ulcerations and infection. The object of this case report is to report our experience of a successful ankle arthrodesis using an anterior T plate in treating the unstable ankle of a diabetic patient, associated with the ankle fracture and the neuropathy. The surgical approach of this technique is simple so that it would allow less soft tissue injury, and this procedure would be regarded as one alternative to provide the rigid internal fixation in the ankle arthrodesis.

Video-assisted thoracoscopic surgery (VATS) has been established as the surgical approach of choice for lobectomy in patients with early-stage non-small cell lung cancer (NSCLC). Patients with clinical stage I NSCLC with no lymph node metastasis are considered candidates for VATS lobectomy. To rule out the presence of metastasis to lymph nodes or distant organs, patients should undergo meticulous clinical staging. Assessing patients' functional status is required to ensure that there are no medical contraindications, such as impaired pulmonary function or cardiac comorbidities. Although various combinations of the number, size, and location of ports are available, finding the best method of port placement for each surgeon is fundamental to maximize the efficiency of the surgical procedure. When conducting VATS lobectomy, it is always necessary to comply with the following oncological principles: (1) the vessels and bronchus of the target lobe should be individually divided, (2) systematic lymph node dissection is mandatory, and (3) touching the lymph node itself and rupturing the capsule of the lymph node should be minimized. Most surgeons conduct the procedure in the following sequence: (1) dissection along the hilar structure, (2) fissure division, (3) perivascular and peribronchial dissection, (4) individual division of the vessels and bronchus, (5) specimen retrieval, and (6) mediastinal lymph node dissection. Surgeons should obtain experience in enhancing the exposure of the dissection target and facilitating dissection. This review article provides the basic principles of the surgical techniques and practical maneuvers for performing VATS lobectomy easily, safely, and efficiently.

Background: Total shoulder arthroplasty (TSA) has been demonstrated to be an effective treatment for multiple shoulder pathologies. The purpose of our study was to compare the relative value units (RVUs) per minute of surgical time for primary and revision TSA. Methods: The American College of Surgeons National Surgical Quality Improvement Program database was queried to identify patients that underwent primary TSA, one-component revision TSA, and two-component revision TSA between January 1, 2015 and December 31, 2017 using current procedure terminology codes. RVUs were divided by mean operative time for each procedure to determine the amount of revenue generated per minute. Rates were compared between the groups using a one-way analysis of variance with post-hoc Tukey test. Statistical significance was set at p<0.05. Results: When dividing compensation by surgical time, we found that two-component revision generated more compensation per minute compared to primary TSA (0.284±0.114 vs. 0.239±0.278 RVU per minute or $10.25±$4.11 vs. $8.64±$10.05 per minute, respectively; p=0.001). Conclusions: The relative value of revision TSA procedures is weighted to account for the increased technical challenges and time associated with these procedures. This study confirms that reimbursement is higher for revision TSA compared to primary TSA.

19 chronic pericarditis patients reviewed who were treated by surgical intervention in the Department of Thoracic and Cardiovascular Surgery, Chonnam University Hospital during the recent 10 years from January of 1968 to January of 1978. 2. There were 14males and 5 females in this series. Range of age varied from 110 days to 61 years. 2. There were two hospital death, one expired 2 days and another 3 days after the pericardiectomy. In both of them, myocardial damage by disease process seemed to be major contributing factor. 2. Clinical and histological study showed tuberculous origin in 8 cases, nonspecific chronic inflammatory changes in 6 cases and pyogenic infection cases in 5 patients. 2. The postoperative complications were observed in 6 cases, and the most common was cardiac arrhythmia and wound infection. 2. The extent of pericardiectomy should be confined to the left and right ventricles to correct the hemodynamic anomaly in general. The results of this procedure has been satisfactory in 89 percent of the cases. 2. Optimal myocardial function in cases of constritive pericarditis was the key to the successful outcome of this procedure.

Objective : Surgical treatment of focal plantar hyperhidrosis is often unsatisfactory compared to palmar hyperhidrosis. The purpose of this study is to evaluate the effect of lumbar sympathetic radiofrequency neurotomy on plantar hyperhidrosis. Methods : From February 2004 to December 2005, 10 patients [mean age 24.3 male 1, female 9] with the clinical diagnosis of plantar hyperhidrosis were treated by bilateral lumbar sympathetic radiofrequency neurotomy of L3 and L4. Patients' symptom relief, satisfactory rate and side effects related to the procedure were analyzed. Results : Radiofrequency neurotomy was effective in the treatment of focal plantar hyperhidrosis showing excellent [more than 75% improved] outcome in 70% of the patients and good [more than 50% improved] in 30%. Complications related to the surgical procedure, such as sensory dysesthesia and compensatory hyperhidrosis were not detected in any case. Conclusion : The use of radiofrequency neurotomy to ablate the lumbar sympathetic ganglion is a safe and effective treatment option for patients with plantar hyperhidrosis.

Robotic surgery have been increasingly applied in the past several years to assist in a variety of operations. Some applications, such as in prostatectomy, have been widely adopted and have largely supplanted the alternative minimally invasive or open techniques. However, the use of surgical robots in esophagectomy has not been as common. Although a limited number of case reports demonstrated the feasibility of robotic esophagectomy, no large series of patients has been reported to date. The data on robotic-assisted esophagectomy suggest that the procedure is safe, feasible, and associated with perioperative outcomes similar to open and minimally invasive esophagectomy. Benefits of robotic system could be maximized when we do a extensive total mediastinal lymphadenectomy. For this procedure to gain widespread acceptance, identifiable benefit relative should be demonstrated in near future.

The purpose of this paper is to discuss the indication. treatment procedure. prognosos and complication of autogenous transplantation in treating impacted teeth of orthodontic patient. Autogenous transplantation is indicated, in cases of rejecting orthodontic treatment due to the visible orthodontic appliance, the relatively long treatment time, unfavorable tooth position for orthodontic repositioning, unrestorable advanced detal caries. advanced periodontitis and ankylosed tooth. Most process related to the decision of the prognosis is dependent on the careful surgical technique. In comparison to other orthodontic and surgical procedure, the application of the autotransplantation is limited, although its success rate is markedly increased today. Therefore we must we must pay attention to the treatment planning and cooperation with other specialties is needed.

A 5-year-old, male mixed breed dog was presented to Gyeongsang National University Animal Hospital for bilateral mandibular open fracture by bite. The dog had loss of the teeth and injury of the oral mucosa. Radio-graphic and blood examinations were conducted. Fracture lines were observed between first premolar and second premolar, but temporomandibular luxation was not observed on radiographs. In serum analysis, elevated levels of CPK and LDH were found. The dog was anesthetized and prepared for aseptic surgery. Acrylic external skeletal fixator with Kirschiner wire was applied. Pin loosening and malalignment of the right fracture line was observed at 7 weeks after surgery. We applied Kirschner-Ehmer fixator and half pins during the second surgical procedure. At 4 weeks after a second surgical procedure, the fixator and pins were removed from mandible. The fractures were healed with no complications.

Accessory navicular is a congenital anomaly of the tuberosity of the navicular from a secondary ossification center. The accessory navicular is occasionally the source of pain and local tenderness over the medial side of midfoot. If conservative treatment fails for the painful accessory navicular, surgical treatment is required. There are several surgical option for accessory navicular, which vary from simple excision, percutaneous drilling, modified Kidner procedure and osteosynthesis of the accessory ossicle to the navicular body. In addition, symptomatic flatfoot deformity should be addressed concomitantly.
