Acute high speed accidents that results in full thickness skin defect and exposure of tendon, nerve, vessel and periosteum over denuded bone demands soft tissue coverage. Exposed bone often ensues chronic infection and requires free flap transplantation which surely covers defects in one stage operation and enhances transport of oxygen-rich blood and converts a non-osteogenic or partially osteogenic site into a highly osteogenic site, but exposed bone which had performed free flap transplantation sometimes necroses and needs secondary bone procedure. Scar contracture limits joint motion should be excised and covered with normal soft tissue to restore normal range of motion. Authors have performed the large latissimus dorsi myocutaneous free flap in 8 cases of extensive soft tissue defect and exposed bone lesion in the leg and 1 case of the flap was failed. The secondary ilizarov bone procedure was performed in 3 of 8 cases. 2 cases of large burn scar contracture and 1 case of posttraumatic scar contracture in lower extremity were restored with the large latissimus dorsi myocutaneous free flap. Authors concluded that large latissimus dorsi myocutaneous free flap is the most acceptable microvascular procedure in large soft tissue defect combined with exposed periosteum and bone requiring secondary bone procedure and in large burn scar contracture limiting knee joint motion.

전북대학교병원 정형외과에서 1993년 12월부터 1998년 9월까지 하지의 만성 골수염 7례에 대하여 유리 근 피판 이식술을 시행하고 최소 1년 2개월부터 최장 5년 3개월까지 추시하여 다음과 같은 임상적 결과를 얻었다. 1. 만성 골수염의 발생 부위는 경골이 4례, 종골 2례 그리고 대퇴골이 1례였다. 2. 만성 골수염의 지속 기간은 평균 31.6년이었다. 3. 전체 7례 중 1례에서 편평 상피암이 발병되었다. 4. 만성 골수염은 4례에서 혈행성 감염으로 초래되었고, 3례는 외상력이 있었는데 2례는 교통사고 그리고 1례는 경미한 외상이었다. 5. 치료는 부골 제거술과 유리 근 이식술을 시행하였던 예가 2례, 부골 제거술없이 유리 근 이식술을 시행한 예가 5례였다. 6. 전체 7례 중 6례에서 유리 근 이식술을 시행하였고 1례에서 유리 근피판 이식술을 시행하였는데 복직 근이 4례였고, 광배 피판, 광배 근피판 그리고 박근이 각각 1례씩이었으며 7례 중 6례(85.7%)에서 생존하였다. 7. 대퇴부에 시행하였던 광배 근피판 1례는 정맥이식술을 통한 단측 문합술을 시행하였으나 술 후 2일째부터 허혈성 변화를 일으켜 실패하였으며, 외상으로 인한 종골 1례에서는 복직근 이식술이 성공하였으나, 술 후 심한 외상성 족관절염으로 인한 극심한 통증으로 슬관절 하부 절단술이 시행되었다. Chronic osteomyelitis have been treated with wound dressing and antibiotics therapy often results in healing but foul odor pus discharges from the fibrotic soft tissues reactivates and requires appropriate control of the infection. Debridement of the wound, curettage and sequestrectomy, bone graft and immediate free flap transplantation is the curative protocol for the chronic osteomyelitis in the lower extremity. Authors have treated 7 cases of chronic osteomyelitis in the lower extremity with microsurgical free tissue transplantation at Department of Orthopedic Surgery, Chonbuk National University Hospital from December 1993 through February 1998. The results are as follows. 1. The chronic osteomyelitis occurred in tibial shaft in 4 cases, in calcaneus 2 cases and in femur 1 case. 2. Duration of the chronic osteomyelitis was at average 31.6 years. 3. Squamous cell carcinoma in the surrounding fibrotic tissue was biopsied in 1 case. 4. 4 cases had no trauma and occurred through hematogenous infection and 3 cases had fracture trauma. 5. Wound debridement and immediate free muscle transplantation had done in 5 cases and wound debridement, sequestrectomy and immediate free muscle transplantation in 2 cases. 6. Rectus abdominis muscle transplantation had peformed in 4 cases(57.1%), latissimus dorsi mucle 1 case(14.3%), latissimus dorsi myocutaneous 1 case(14.3%) and gracilis 1 case (14.3%). 6 cases of 7 were success(85.7%). 7. 1 case of failed latissimus dorsi musculocutaneous flap in thigh had done above knee amputation and 1 case of chronic posttraumatic osteoarthritis of the ankle joint had done below knee amputation at other hospital.

Therapy of pulmonary hypertension is limited by the low potency and adverse effects of current pulmonary vasodilators. The hemodynamic effects of nitroglycerin in human pulmonary hypertension are not clear. But some reported that nitroglycerin produced pulmonary venodilation at doses that do not affect the systemic arterial vasculature, so it may not decrease systemic arterial pressure, We administered nitroglycerin to 14 patients with chronic pulmonary hypertension. Nitroglycerin decreased mean pulmonary arterial pressure by 19%, pulmonary vascular resistance by 25% and systemic arterial pressure by 11%, but did not affect heart rate, cardiac out- put, pulmonary capillary wedge pressure and arterial oxygen tension. Among these patients, nitroglycerin was more effective in patients with moderate pulmonary hypertension(mean pulmonary arterial pressure: 30~49 mmHg) and there were no side effects during this study procedure. We conclude that therapy with nitroglycerin can be effective in patient with pulmonary hypertension, especially in those with moderate degree of pulmonary hypertension.

A simple imaging procedure has been devised for patients with peritoneo-venous shunts when ascites reaccumulates and a decision must be made on whether or not to revise the shunt. We recently experienced a patient with reaccumulated ascites in whom obstruction of peritoneo-venous shunt was suspected. 5 mCi of 99mTc-phytate was injected into the peritoneal cavity and imaging of the abdomen was performed 1~30 minutes later. With a proper funtioning shunt, radioactivity in the liver and spleen were easily identifiable in this case. If the shunt is obstructed, tracer activity will remain in the pediotoneal cavity and thus can not be identifiable m the liver or spleen. Conclusively, radionuclide methods might be very useful for evaluation of peritoneo-venous shunt patency.
