Purpose: To compare and analyze the outcome of primary clavicular lateral end resection method and conventional acromioclavicular (AC) joint reduction method in type III AC dislocation patients over 45 years. Materials and Methods: This study was performed on selected 24 cases of type III AC dislocation patients, over 45 years of age, operated at our hospital from 1998 to 2002. Group I consist of 12 patients who underwent primary clavicular lateral end resection methods (average age: 54.3 years$(45{\sim}72)$). Group II consist of 7 patients using Bosworth methods and 5 patients using Phemister methods (average age: 54.4 years$(45{\sim}71)$). Clinical outcome was evaluated by Weaver and Dunn method. Radiological results were compared by measuring coracoclavicular distance between normal and injured side. Results: As clinical outcome, good was 10 cases(83%); fair 2(17%) in Group I, and good 6(50%); fair 3(25%); poor 3(25%) in Group II. In contrast, the difference of coracoclavicular distance was not statistically significant between two groups before or after surgery, and last follow up. At the last follow up, there was no special correlation between the difference of coracoclavicular distance and clinical outcome. Conclusion: We considered that primary clavicular lateral end resection may be effective for prevention of arthrosis in AC joint in type III AC dislocation patients over 45 years.

Background: The late progression of tricuspid regurgitation (TR) after mitral valve surgery is well known. However, few reports have described the progression of TR after aortic valve surgery. We investigated the incidence of and risk factors for the development of significant TR after isolated aortic valve replacement (AVR). Methods: This study analyzed patients with less than moderate TR who underwent isolated AVR at Seoul National University Hospital from January 1990 to December 2018. Significant TR was defined as moderate or higher. Echocardiographic follow-up was performed in all patients. The Fine-Gray model was used to identify clinical risk factors for the development of significant TR. Results: In total, 583 patients (61.7±14.2 years old) were included. Operative mortality occurred in 9 patients (1.5%), and the overall survival rates at 10, 20, and 25 years were 91.1%, 83.2%, and 78.9%, respectively. Sixteen patients (2.7%) developed significant TR during the follow-up period (13 moderate; 3 severe). The cumulative incidence of significant TR at 10, 20, and 25 years was 0.77%, 3.83%, and 6.42%, respectively. No patients underwent reoperation or reintervention of the tricuspid valve. Hemodialysis or peritoneal dialysis for chronic kidney disease (hazard ratio [HR], 5.188; 95% confidence interval [CI], 1.154-23.322) and preoperative mild TR (HR, 5.919; 95% CI, 2.059-17.017) were associated with the development of significant TR in the multivariable analysis. Conclusion: TR progression after isolated AVR in patients with less than moderate TR is rare. Preoperative mild TR and hemodialysis or peritoneal dialysis for chronic kidney disease were significant risk factors for the development of TR.

Pulp and palm of the hand and heel of the sole are anatomically unique. Satisfactory reconstruction of these areas presents the plastic surgeon with many challenges and requires durable and sensible skin coverage, minimal donor morbidity and reliable operative procedure. We presents 7 clinical cases of sensate instep free flap transfer in this paper during the last 2 years. Three cases were soft tissue defects due to crushing and avulsion injury on the pulp of finger. 1 case was unstable scar and redundant flap after reconstruction of soft tissue dect of palm and 1 case was contracture of first web of hand. One case was a soft tissue defect due to avulsion injury on heel. Lastly, one case was chronic osteomyelitis with open wound on lateral malleolar area. Follow-up period ranged from 3 months to 2 years. Through the whole follow-up period, all flaps were viable and durable to persistant stress or weight bearing and were sensible enough to porotect the recocstructed area from injuries and maintain functions. In conclusions, the instep free flap should be considered as a valuable tool in reconstruction of hand and extremity requiring durability and sensation.

Purpose: The purpose of this study was to document the results of fixation with ethibond suture in akin osteotomy and its advantages. Materials and Methods: From May 2001 to January 2004, Akin osteotomy was performed in 218 patients. We reviewed 110 patients (114 feet) who were possible radiographic evaluation more than 6 months after operation. 110 feet had hallux valgus and 4 feet had hallux valgus interphalangeus. 105 patients were female and 5 were male. The average age was 43.8 years old (18 to 68 years old). The average follow up was 9 months (6 to 23 months). After performing the Akin osteotomy at 7 mm from the proximal articular surface of the proximal phalanx, one hole is made on either side of the osteotomy site with a K-wire. The passer was passed through the both holes and the ethibond was passed. And then, the ethibond was tied tightly. 2 sutures in 66 feet and 1 suture in 48 feet were made. Radiographic bone union at 6 months follow up was regarded as success and loss of the reduction, nonunion was regarded as failed. Results: In the radiographic evaluation, bony union were made at 6 months follow up in all feet. There was no difference between 2 sutures and 1 suture, and the knots were removed in 3 feet because of skin irritation. Conclusion: The fixation of the osteotomy site using suture material was an effective method in Akin osteotomy. The advantage of this procedure was unnecessity of the material removal.

Background: To determine the predictive value of the baseline stimulated thyroglobulin (STg) level for ablation outcome in patients undergoing adjuvant remnant radioiodine ablation (RRA) for differentiated thyroid carcinoma (DTC). Materials and Methods: This retrospective study accrued 64 patients (23 male and 41 female; mean age of $40{\pm}14$ years) who had total thyroidectomy followed by RRA for DTC from January 2012 till April 2014. Patients with positive anti-Tg antibodies and distant metastasis on post-ablative whole body iodine scans (TWBIS) were excluded. Baseline STg was used to predict successful ablation (follow-up STg <2 ng/ml, negative diagnostic WBIS and negative ultrasound neck) at 7-12 months follow-up. Results: Overall, successful ablation was noted in 37 (58%) patients while ablation failed in 27 (42%). Using the ROC curve, a cut-off level of baseline STg level of ${\leq}14.5ng/ml$ was found to be most sensitive and specific for predicting successful ablation. Successful ablation was thus noted in 25/28 (89%) of patients with baseline STg ${\leq}14.5ng/ml$ and 12/36 (33%) patients with baseline STg >14.5 ng/ml ((p value <0.05). Age >40 years, female gender, PTS >2 cm, papillary histopathology, positive cervical nodes and positive TWBIS were significant predictors of ablation failure. Conclusions: We conclude that in patients with total thyroidectomy followed by I-131 ablation for DTC, the baseline STg level is a good predictor of successful ablation based on a stringent triple negative criteria (i.e. follow-up STg < 2 ng/ml, a negative DWBIS and a negative US neck).

Background: For AVR using conventional prosthetic valves in adult patients with a narrow aortic root, aortic root enlargement is necessary to reduce postoperative pressure gradient across the aortic valve (ΔP). An evaluation of early and mid-term results of aortic root enlargement with AVR and echocardiographic follow up of ΔP and left ventricular function was performed. Method: From Aug. 1991 to Feb. 1998, eighteen patients aged 17 to 59 years(mean, 38$\pm$12 years) underwent Manouguian procedure with AVR. Aortic annular circumstance was enlarged 10.0mm to 18.0mm(mean, 12.6$\pm$6.3mm). Eight patients(44.0%) had NYHA class III status before operation, and seven cases of them underwent concomitant MVR. Valve pathology was ASr in 6 cases, AS in 4 cases, nd ASr+MSr in 8 cases. Replaced valve size was 21mm in 8 cases and 23 mm in 10 cases, and St. Jude Medical mechanical valve was used in 10 cases and Carbomedics in 8 cases. Result: Follow-up duration was 6 to 57 months (mean, 26$\pm$18 months), and total follow-up was 287 patient-year. There were one hospital death and one late death, therefore, actuarial survival rate was 85.7% at 56 months. Peak ΔP wad decreased significantly at postoperative mid-term period as 13$\pm$5mmHg, compared with thepreoperative one (42$\pm$8mmHg) (p<0.01). LVM(gm/$m^2$) was also diminished as 35.8%(115$\pm$36gm/$m^2$)at postoperative mid-term period, compared with preoperative one (179$\pm$56gm/$m^2$)(p<0.05). Conclusion: There were no specific complications related to the procedure. And we could have adequate enlargement of aortic annulus to suitable prosthetic valve that have no effect of patient-prosthese mismatch.

The primary aim of this systematic review was to assess the evidence on periodontal disease progression after treatment in patients receiving supportive periodontal therapy (SPT) and to identify predictors of clinical attachment level (CAL) loss. A protocol was developed to answer the following focused question: In adult patients treated for periodontitis, what is the disease progression in terms of CAL loss after surgical or non-surgical treatment? Randomized controlled clinical trials, prospective cohort studies, and longitudinal observational human studies with a minimum of 5 years of follow-up after surgical or non-surgical treatment that reported CAL and probing depth changes were selected. Seventeen publications reporting data from 14 investigations were included. Data from 964 patients with a follow-up range of 5-15 years was evaluated. When the CAL at the latest follow-up was compared to the CAL after active periodontal therapy, 10 of the included studies reported an overall mean CAL loss of ${\leq}0.5mm$, 3 studies reported a mean CAL loss of 0.5-1 mm, and 4 studies reported a mean CAL loss of >1 mm. Based on 7 publications, the percentage of sites showing a CAL loss of ${\geq}2mm$ varied from 3% to 20%, and a high percentage of sites with CAL loss was associated with poor oral hygiene, smoking, and poor compliance with SPT. The outcomes after periodontal therapy remained stable over time. Disease progression occurred in a reduced number of sites and patients, mostly associated with poor oral hygiene, poor compliance with SPT, and smoking.
