From January 1990 to December 1998, 449 consecutive single-digital replantations were reviewed retrospectively in order to determine the essential number of vascular anastomoses for successful finger replantation. The correlations between the number of anastomosed vessels and survival rate were examined according to the amputated digital levels and all of the correlated results were compared with each other statistically. In zone I, The survival rate of the digits with a repaired vein was higher than that of digits treated with external bleeding method. In zone II, the equal number(s) between the arterial and venous repair was an important factor in successful replantation. And the repaired arteries more than repaired veins in number led to venous congestion and resulted in a failure of replantation, which was maybe due to the large amount of arterial input relative to small volume of amputated stump with small sized vein. In zone III, the equal number(s) between the arterial and venous repair was also an important factor in successful replantation. But unlike in zone II, venous congestion was scarcely happened if the venous drainage was sufficient with a repaired large vein alone. In zone IV, two or more arteries and veins were required for successful replantation. In conclusion, it is desirable that the repair of vessels as many as possible to increase the possibility of a good result. But digital amputations and their condition for replantation were variable, therefore, the numbers in vascular repair should to be modified and straightforward as the case may be.

Background Aggressive treatment of sternoclavicular joint (SCJ) infection involves systemic antibiotics, surgical drainage and resection if indicated. The purpose of this paper is to describe a classification of post resectional SCJ defects and highlight our reconstructive algorithm. Defects were classified into A, where closure was possible often with the aid of topical negative pressure dressing; B, where parts of the manubrium, calvicular head, and first rib were excised; and C, where both clavicular, first ribs and most of the manubrium were resected. Methods Twelve patients (age range, 42 to 72 years) over the last 8 years underwent reconstruction after SCJ infection. There was 1 case of a type A defect, 10 type B defects, and 1 type C defect. Reconstruction was performed using the pectoralis major flap in 6 cases (50%), the latissimus dorsi flap in 4 cases (33%), secondary closure in 1 case and; the latissimus and the rectus flap in 1 case. Results All wounds healed uneventfully with no flap failure. Nine patients had good shoulder motion. Three patients with extensive clavicular resection had restricted shoulder abduction and were unable to abduct their arm past $90^{\circ}$. Internal and external rotation were not affected. Conclusions We highlight our reconstructive algorithm which is summarised as follows: for an isolated type B SCJ defect we recommend the ipsilateral pectoralis major muscle for closure. For a type C bilateral defect, we suggest the latissimum dorsi flap. In cases of extensive infection where the thoracoacromial and internal mammary vessels are thrombosed, the pectoralis major and rectus abdominus cannot be used; and the latissimus dorsi flap is chosen.

본 연구의 목적은 규칙기반 모델링을 구성하여 하계망을 일반화하고자 하였다. 그 동안 지도 일반화에 대한 연구는 제한된 지도요소를 대상으로 선형사상의 형태변형을 위한 알고리즘 개발과 평가에 집중되었다. 규칙 기반 모델링은 지도제작 원리와 공간현상의 분포패턴을 분석하여, 그 결과를 일반화 과정에 적용하기 때문에 기존의 일반화 알고리즘 개선에 도움이 된다. 규칙기반 모델링은 다양한 지도요소들을 대상으로 일반화를 적용할 수 있고, 디지털 환경하에서 다축척 지도제작에 효과적이다. 본 연구에서 개발된 하계망 규칙기반 모델링은 일반화 규칙, 중심선 추출 그리고 선형사상 일반화 알고리즘으로 구성된다. 일반화를 적용하기 앞서, 하계망은 논리적 오류를 최소화하기 위해 저수지와의 연결관계를 분석하였다. 모델을 적용한 결과, 108개의 실폭 하천 중 17개 하천이 중심선으로 추출되었다. 하천의 총길이는 1:25,000에서 17%, 1:50,000에서는 29%로 감소하였다. 선형사상 일반화를 위해 개발된 Simoo 알고리즘은 Douglas-Peucker 알고리즘과 비교하였다. Doug]as-Peucker 알고리즘은 자료점 간격과 편각이 커지게 되어 선의 형태가 거칠어지는 반면, Simoo 알고리즘에서 선형사상은 축척이 감소함에 따라 보다 완만해진다.

Pressure sores are an ulceration and necrosis of the skin and underlying tissue usually occur after prolonged or repeated pressure by interruption of blood flow from the small. vessels to the skin and deep tissue. The management of pressure sores is mostly difficult and requires prolonged hospitalization or repeated surgical interventions with a high recurrence rate. In this article we reviewed 14 cases of National Pressure Ulcer Advisory Pannel staging III, IV over the lateral malleolar area of the ankle in 2 years period from January 1999 to October 2001. The pressure over lateral malleolar area was mainly due to unique Korean sitting position with cross legs at flexed hips and knees or supine position of patient with external rotation of low extremity. Male to female ratio was 11: 3 and ages were between 36 and 83 (mean age: 67.1 years). Associated diseases were DM(7 cases), Hemiparesis caused by CVA(2 cases), Liver cirrhosis(2 cases), disarticulation of opposite hip due to squamous cell ca.(1 case), Intertrochanteric Fx.(1 case). Wound cultures reported Staphylococus, Pseudomonas and others. Abnormally elevated ESR and CRP were seen in 6 cases. Operative treatments were irrigation and debridement, direct closure with gravity drainage and skin grafting. The most important aspect of pressure sore treatment is pressure relief of the lateral malleolar area. Pressure-relieving Cast or Brace was helpful for local management and preventing recurrence.

Purpose: Recently, replantation of fingertip amputation, Zone I by Yamano classification, is still difficult because digital arteries branch into small arteries and also digital veins are hard to separate from the immobile soft tissue. However the replantation of fingertip in adults is a well-established procedure, but the replantation in infant or child is still uncommon. Therefore we present one case of replantation of the fingertip of the small finger in 12-months-old patient. Methods: We experienced a 12-months-old male amputation of small finger. It had been amputated completely at the level of Zone I by Yamano classification. Replantation was performed using the arteryonly technique with neither vein nor nerve repair. Because the artery has been damaged, it is still possible to make a direct suture by transposing the arterial arch in an inverted Y to I arterial configuration. Venous drainage was provided by an external bleeding method with partial nail excision and repaired margin for approximately 7 days. Results: We were performed replantation in infant with only-arterial anastomosis successfully, result in good recovery of aesthetic and functional outcome. Conclusion: In conclusion, although fingertip injury was difficult to replantation in infant and child, we must try it. Because of its functional and cosmetic advantage.

Purpose : The purpose of this study was to determine the effects of upper extremity volume, pain, and range of motion after participation in thera-band exercises according to the hand grip type in patients with breast cancer with upper extremity edema. We also aimed to determine the most efficient type of grip. Methods : The subjects were 10 female patients diagnosed with stage 2 breast cancer who had stage 2 lymphedema. Randomly, 5 patients each were allocated to the experimental and control groups. For six weeks, the patients in both the experimental and control groups exercised daily. In both groups, manual lymph drainage was applied for 1 hour. Afterward, patients in the experimental group placed their hands in the thera-band ring and exercised with their fingers outstretched. Patients in the control group exercised while holding the thera-band ring with a finger. Both the experimental group and the control group underwent measurements of the circumference of the upper extremity, pain, and range of motion of the shoulder joint at weeks 1, 2, 4, and 6 before and after exercise. Results : The upper arm circumference decreased by more in the experimental group in all weeks than before than that in the control group, and there was a statistically significant difference at 6 weeks. Compared with the difference between pre-exercise and 6 weeks post-exercise, the change in pain significantly decreased in the experimental group and showed a statistically significant difference. The shoulder range of motion increased in extension, external rotation, and internal rotation compared with that in the control group, and there was a statistically significant difference. Although the operating range increased in flexion and abduction, there were no statistically significant differences. Conclusion : In this study, we found that thera-band exercises with an open-hand grip are more efficient than thera-band exercises with a closed-hand grip in edema reduction, pain, and range of motion. In addition, it was found that it was more effective to continue the thera-band exercises with open-hand grip extended for at least 6 weeks rather than for a short time.

Purpose: In the finger, there are three major palmar arches in the arterial system. The location of this arches are constant. The middle and distal transverse arches are consistently large (almost 1 mm) and may be used for arterial vessel repairs either proximally or distally, depending on the length and direction needed. This paper describes our experiences in reconstruction and replantation of the finger using rerouting the transverse digital palmar arch. Methods: 31 patients with injuries according to our classification were treated from March of 2005 to October of 2008. In this study the authors subdivided injuries into those with amputation distal to the insertion of the flexor digitorum profundus (Class I, 31 fingers); those with amputation distal to the insertion of the flexor digitorum superficialis (Class II, 4 fingers). Replantation was performed using the artery-only technique with neither vein nor nerve repair. Because the artery has been damaged, it is still possible to make a direct suture by transposing the arterial arch in an inverted Y to I arterial configuration or converting the arch. Venous drainage was provided by an external bleeding method with partial nail excision, medical leech, and repaired margin. Results: The success rate was 87% (n=27) in class I and 75% (n=4) in class II. The authors conclude that crushing and complete avulsion injuries & amputations are salvageable, with acceptable functional results in select patients, especially those with amputation distal to the insertion of the flexor digitorum superficialis. Conclusion: We performed replantation and reconstruction with only-arterial transposing anastomosis successfully, resulting in good recovery of aesthetic and functional outcome. Three major digital palmar arches, especially distal two branches, give us additional treatment options. In the finger replantation and reconstructive techniques using rerouting healthy the transverse digital palmar arch increase the survival rate of the finger.

Purpose: Even though traumatic pancreatic injuries occur in only 0.2% to 4% of all abdominal injuries, the morbidity and the mortality rates associated with pancreatic injuries remain high. The aim of this study was to evaluate the clinical outcomes of traumatic pancreatic injuries and to identify predictors of mortality and morbidity. Methods: We retrospectively reviewed the medical records of 26 consecutive patients with a pancreatic injury who underwent a laparotomy from January 2000 to December 2010. The data collected included demographic data, the mechanism of injury, the initial vital signs, the grade of pancreatic injury, the injury severity score (ISS), the revised trauma score (RTS), the Glasgow Coma Scale (GCS), the number of abbreviated injury scales (AIS), the number of associated injuries, the initial laboratory findings, the amount of blood transfusion, the type of operation, the mortality, the morbidity, and others. Results: The overall mortality rate in our series was 23.0%, and the morbidity rate was 76.9%. Twenty patients (76.9%) had associated injuries to either intra-abdominal organs or extra-abdominal organs. Two patients (7.7%) underwent external drainage, and 18 patients (69.3%) underwent a distal pancreatectomy. Pancreaticoduodenectomies were performed in 6 patients (23.0%). Three patients underwent a re-laparotomy due to anastomosis leakage or postoperative bleeding, and all patients died. The univariate analysis revealed 11 factors (amount of transfusion, AAST grade, re-laparotomy, associated duodenal injury, base excess, APACHE 11 score, type of operation, operation time, RTS, associated colon injury, GCS) to be significantly associated with mortality (p<0.05). Conclusion: Whenever a surgeon manages a patient with traumatic pancreatic injury, the surgeon needs to consider the predictive risk factors. And, if possible, the patient should undergo a proper and meticulous, less invasive surgical procedure.
