Background: The purpose of this study was to evaluate and compare deltoid origin status following large rotator cuff repair carried out using either an open or an arthroscopic method with a propensity score matching technique. Methods: A retrospective review of 112 patients treated for full-thickness, large rotator cuff tear via either a classic open repair (open group) or an arthroscopic repair (arthroscopic group) was conducted. All patients included in the study had undergone postoperative magnetic resonance imaging (MRI) and clinical follow-up for at least 12 and 18 months after surgery, respectively. Propensity score matching was used to select controls matched for age, sex, body mass index, and affected site. There were 56 patients in each group, with a mean age of 63.3 years (range, 50-77 years). The postoperative functional and radiologic outcomes for both groups were compared. Radiologic evaluation for postoperative rotator cuff integrity and deltoid origin status was performed with 3-Tesla MRI. Results: The deltoid origin thickness was significantly greater in the arthroscopic group when measured at the anterior acromion (P=0.006), anterior third (P=0.005), and middle third of the lateral border of the acromion level (P=0.005). The deltoid origin thickness at the posterior third of the lateral acromion was not significantly different between the arthroscopic and open groups. The arthroscopic group had significantly higher intact deltoid integrity with less scarring (P=0.04). There were no full-thickness deltoid tears in either the open or arthroscopic group. Conclusions: Open rotator cuff repair resulted in a thinner deltoid origin, especially from the anterior acromion to the middle third of the lateral border of the acromion, at the 1-year postoperative MRI evaluation. Meticulous reattachment of the deltoid origin is as essential as rotator cuff repair when an open approach is selected.

배경: 대동맥 축착증과 심실중격결손이 동반된 환아의 적절한 치료 방침에 대해서는 이견이 많다. 본 연구는 생후 6개월 이하의 환아에서 대동맥 축착증과 심실중격결손의 일타 완전교정 결과 및 수술방법에 따른 대동맥 축착증의 재발에 대해 알아보고자 하였다. 대상 및 방법: 1995년 1월부터 2000년 12월가지 본원에서 대동맥 축착증과 심실중격결손으로 일차 완전교정을 시행받은 생후 6개월 이하의 환아 33명을 대상으로 후향적으로 조사하였다. 환아의 평균 연령과 체중은 각각 54$\pm$37일(12일~171일)과 3.9$\pm$1.1kg(1.5~6kg)이었다. 대동맥 축착 고정은 연구 초기에는 저체온하 완전순환정지하에서 시행하였으며 최근에는 순환정지없이 무명동맥을 통한 국소 뇌관류 상태에서 시행하였다. 축착증 교정 방법은 초기에는 Extended cad-to-end anastomosis(EEEA;n=16)와 Extended side-to-side anastomosis(ESSA;n=2)를, 최근에는 Extended end-to-sidc anasto mosis(EESA;n=15)를 이용하였다 심실중격결손은 초기 16명에서는 Dacron을, 최근 17명에서는 자가 심낭편을 이용하여 폐쇄하였다. 대동맥궁 발육부전은 29명(88%)에서 있었으며 원위부 발육부전 18명, 완전형 5명, 그리고 복잡형은 6명이었다.

목적: 해부학적 봉합이 불가능한 대파열 및 광범위 회전근 개 파열에서 관절경하 모서리 맞춤 술식을 이용한 봉합술의 결과를 분석하고자 하였다. 대상 및 방법: 2008년 1월부터 2009년 6월까지 대파열 및 광범위 회전근 개 파열 환자 중에서 관절경하 모서리 맞춤 술식을 이용하여 비해부학적 봉합을 시행한 환자 중 1년 이상 추시가 가능하였던 22예를 대상으로 하였다. 수술 전 견관절 전후 방사선 사진 상 상완 골두의 상방 전이를 측정하였고, 수술 후 6개월에 MRI 검사와 최종 추시 시에 KSS, UCLA score, Visual analogue scale (VAS)을 이용한 기능평가를 시행하였다. 결과: 22예의 환자 중 11예에서 수술 후 6개월에 시행한 MRI 검사상 양호한 치유 3예, 부분적 치유 4예, 재파열 4예였다. 술 전 및 술 후 최종 추시 시의 KSS는 평균 45.0${\pm}$8.014점에서 77.1${\pm}$10.151점으로, UCLA score는 평균 10.8${\pm}$2.302점에서 30.0 ${\pm}$1.521점으로 전반적으로 향상되었고, VAS는 평균 7.7${\pm}$0.616점에서 3.0${\pm}$1.021점으로 감소하였다. 술 전 MRI 상 fatty degeneration 정도가 Grade 3 이상일 경우 기능적 결과가 좋지 않은 것으로 나타났다. 결론: 해부학적 봉합이 힘든 대파열 및 광범위 회전근 개 파열에서 관절경하 모서리 맞춤 술식을 이용한 부분적 봉합은 유의한 통증 감소와 좋은 기능적 결과를 보였다.

Reinforced concrete structure can be strengthened by glass fiber reinforced plastic thin panels. The GFRP-Thin Panels are manufactured by pressing form and their application technique are similar to steel plates. The use of FGRP-Thin Panels presents several advantages. The advantages of this structural system are the case of application, the elimination of joint and corrosion at the epoxy-panel interface. This paper introduces the method of manufacturing about GFRP-Thin Panels, mechanical properties and the application of reinforced concrete structures.

This is a review article of the wide-awake approach to hand surgery. More than 95% of all hand surgery can now be performed without a tourniquet. Epinephrine is injected with lidocaine for hemostasis and anesthesia instead of a tourniquet and sedation. This is sedation-free surgery, much like a visit to a dental office. The myth of danger of using epinephrine in the finger is reviewed. The wide awake technique is greatly improving results in tendon repair, tenolysis, and tendon transfer. Here, we will explain its advantages.

Bentall`s operation for repair of annuloaortic ectasia has been associated with postoperative bleeding and with false aneurysm of the anastomotic site between the coronary orifice and composite graft.Among 5 cases, 2 cases have been operated direct anastomosis between coronary artery and vascular graft.Remained 3 cases have been operated with doughnutlike Teflon felt buttress.The technique of sandwiching the freed button of aortic wall bearing the coronary artery ostium between an outer Teflon felt doughnutlike buttress and the inner composite graft provides a leak-proof anastomosis.We experienced one case reoperation for bleeding at coronary anastomotic site above method.

의치(denture) 파절조각(fracture segment)의 조립을 정확하고 쉽게 부착시킬 수 있는 cyanoacrylate의 사용을 권장하고 싶다. 이 수리 방법은 환자가 오랜기간 동안 보철물 없이 존속하는 것을 막기 위해 석고모형(stone cast)을 부울 필요없이 신속하게 수리하는 방법이다. 더불어 의치(denture)가 많은 조각으로 파절 되었기 때문에 전통적인 방법에 의해서는 수리가 가능치 않다고 생각 될 경우에는 이 방법이 좋으리라 생각되어 소개하는 바 입니다.

Ex vivo lung perfusion (EVLP) is a technique that enables active metabolism of the lung by creating an environment similar to that inside the body, even though the explanted lungs are outside the body. The EVLP system enables the use of lung grafts that do not satisfy the acceptance criteria for lung transplantation (LTx) by making it possible to evaluate the function of the lung grafts and repair lungs in poor condition, thereby reducing the waiting time of patients requiring LTx and consequently mortality.

Purpose: To describe a technique of the modified Neviaser method and to evaluate the clinical outcome of the technique in the treatment of the complete acromioclavicular joint dislocation, Materials and Method: We evaluated 20 patients who were treated by a modified Neviaser method from June 1996 to January 1999, They were followed up for a minimum of two years. The operative technique includes fixation of the acromioclavicular joint, repair of coracoclavicular ligament and transfer of the anterolateral band of coracoacromial ligament. Results: The 20 patients were evaluated clinically using Kang's criteria. The satisfactory results obtained in 85%. The mean coracoclavicular interval ratio was decreased from 2.22 preoperatively to 1.07 postoperatively. At the time of two year follow-up, the mean ratio was 1.20. There was no definite complication such as re-dislocation of the joint. Conclusion: In above type 3 acromioclavicular dislocation, the modified Neviaser method provided the advantage of strong and stable fixation with a low complication rate. Therefore, it is thought to be one of the useful operative technique.
