소아 전방 십자인대 견열 골절은 비교적 드물게 발생하며, 주로 청소년기에 발생하고 경쟁 경기 중의 발생빈도가 증가하고 있다. 수술 후 합병증을 감소시키기 위해 최근에는 관절경적 수술방법이 많이 사용되고 있다. 나사못, K-강선, 봉합 나사못 등이 사용되고 있으며, 유관 나사못 고정술은 수술 술기가 가장 간단하나 단점으로 성장판 손상의 가능성이 있다. 저자들은 8세 여아의 전방 십자인대 견열 골절에서 관절경을 이용한 유관 나사못 고정술로 좋은 결과를 얻었기에 문헌 고찰과 함께 보고하는 바이다.

Popliteal artery injury in blunt trauma of knee joint is not common but poses high rate of amputation due to anatomical characteristics or delayed diagnosis and treatment. The aim of the present study is to review the authors' experiences with this condition and identify factors contributing to disability. We reviewed 7 cases of popliteal artery injury in trauma around knee. Injury mechanism, type of vessel damage, associated injuries, mangled extremity severity scores (MESS), ischemic time and additional treatments were analyzed. Tibial fracture, distal femoral fracture and serious soft tissue defect were combined. Mean MESS was 9.9 point and mean time of revascularization was 7.1 hours. Transfemoral amputation was performed in 2 cases due to vascular insufficiency and devastating infection, and 4 patients were able to walk without any support at the last follow up. Age, the severity of soft tissue injury, ischemic time and MESS are thought to be related to prognosis, and young patients with short ischemic time show best results, but authors experienced one exceptional case. We have to consider multiple factors related to the prognosis in popliteal artery injury with fractures around knee, and careful decision is needed regarding to early amputation.

목적 : 급성 족 관절 골절에서 족 관절경을 이용하여 관절내 잠재 손상의 관찰 및 발생을 예측하기 위한 인자를 알아보고자 하였다. 대상 및 방법 : 50명의 전위가 심하지 않은 급성 족 관절 환자 50명을 대상으로 전향적인 방법으로, 족 관절경을 시행하여 관절내 각 부위에서의 잠재 손상의 종류를 조사하였으며, 족 관절 골절을 Lauge-Hansen, AO 및 골절의 해부학적 위치에 따라 분류하여 특정한 유형에서 잠재 손상의 빈도가 증가되는가를 관찰하였다. 결과 : 50례의 족 관절 골절 중 37례에서 잠재 손상이 관찰되었으며, 전위된 골편을 포함한 유리체가 25례에서 관찰되었고, 31례에서 다양한 종류의 연골 손상이 관찰되었다. 방사선 사진상 관찰되지 않는 잠재 골절이 3례에서, 전하 경비 인대의 경골 부착부에서의 견열 골편이 6례에서 각각 관찰되었다. 환자의 연령, 성별, 수상기전 및 족 관절 골절의 여러 유형과 잠재 손상 발생 빈도와의 연관성은 관찰되지 않았다(p>0.05). 결론 : 단순 족 관절 골절에서 다양한 종류의 잠재 손상이 관찰되었으며, 족 관절경은 잠재 손상의 관찰뿐만 아니라 그 치료에도 매우 유용한 방법으로 사료되었으나, 족 관절 골절에서 잠재 손상의 발생을 정확히 예측하기는 어려웠다.

Introduction: Surgical treatment of subclavian artery (SA) injury is challenging because approaching the lesion directly and clamping the proximal artery is difficult. This can be overcome by using an endovascular technique. Case 1: A 37-year-old male was drawn into the concrete mixer truck. He had a right SA injury with multiple traumatic injuries: an open fracture of the right leg with posterior tibial artery (PTA) injury, a right hemothorax, and fractures of the clavicle, scapula, ribs, cervical spine and nasal bone. The injury severity score (ISS) was 27. Computed tomography (CT) showed a 30-mm-length thrombotic occlusion in the right SA, which was 15 mm distal to the vertebral artery (VA). A self-expandable stent($8mm{\times}40mm$ in size) was deployed through the right femoral artery while preserving VA flow, and the radial pulse was palpable after deployment. Other operations were performed sequentially. He had a viable right arm during a 13-month follow-up period. Case 2: A 25-year-old male was admitted to our hospital due to a motorcycle accident. The ISS was 34 because of a hemothorax and open fractures of the mandible and the left hand. Intraoperative angiography was done through a right femoral artery puncture. Contrast extravasation of the SA was detected just outside the left rib cage. After balloon catheter had been inflated just proximal to the bleeding site, direct surgical exploration was performed through infraclavicular skin incision. The transected SA was identified, and an interposition graft was performed using a saphenous vein graft. Other operations were performed sequentially. He had a viable left arm during a 15-month follow-up period. Conclusion: The challenge of repairing an SA injury can be overcome by using an endovascular approach.

A free rectus abdominis flap can include a variable amount of muscle length depending on recipient site requirements. There is also great flexibility in flap design in terms of size, orientation of its axis, and the level of its location over the muscle. It is safe to design the skin island across the midline. Though skin islands designed over the most inferior portion of the abdomen have not always proved reliable when based on the superior epigastric artery, free flaps based on the inferior pedicle can be successfully designed in this area. As free flap based on the inferior epigastric vessels, this flap has been useful for large head and neck defects following ablative procedures, for facial contour restoration as a buried flap, for upper extremity defects, for lower extremity defects such as coverage of grade III tibial fractures and for breast reconstruction. A free rectus abdominis muscle or myocutaneus flap was used in 8 patients. The operations were performed between Sep. of 1994 and April of 1996. The patients were tongue cancer 1 case, chronic facial palsy 1 case, unilateral breast reconstruction 1 case, upper and lower extremity injury 5 cases. The free rectus abdominis muscle flaps were 4 cases and the free myocutaneous flaps were 4 cases. There was no failure of the flap, except one partial necrosis. One case of the skin grafts on the muscle flap was regrafted. One case of reoperation due to venous thrombosis was performed. In tongue cancer patient, a orocutaneous fistula was occurred, but conservative treatment and secondandry skin graft were done. In conclusion, a free rectus abdominis flap has many advantages such as a long and constant pedicle, easy dissection, enough soft tissue available, scar on the donor site to be hiddened, no need for changing position. So we think that this flap is the most useful one for small or moderate sized defects on the various sites.

February 1995 to September 1999, authors have experienced seven cases of infected nonunion of tibial fractures with associated soft tissue injury and skin defect, and have accomplished union in all cases by free vascularized fibular graft. All grafts healed with no radiographic evidence of bone necrosis or resorption and have been able to treat large bony defect and skin defect simultaneously. In this study, five cases of vascularized free fibular osteocutaneous flap transfer and two cases of free fibular graft are reported. All of seven cases were infected nonunion of tibia. The results were obtained as follows 1) The mean duration of the radiologic bone union was average 5.3months. 2) Grafted fibular has been hypertrophied, average 10.6 months. 3) In five cases of preservation of posterior cortex of tibia, bony union and hypertrophy of grafted bone were earlier than that two cases of complete segmental resection of tibia. 4) In two cases which only free vascularized fibular graft were performed because achievement of cutaneous flap was failed, authors found that soft tissue defect was filled with granulation tissue and split-thickness skin graft was possible over the granulation tissue after 3 weeks postoperatively.

Background Free muscle flaps are a mainstay for reconstruction of distal third leg wounds and for large lower extremity wounds with exposed bone. However a major problem is the significant postoperative flap swelling, which may take months to resolve. We studied the efficacy and safety of immediate application of a vacuum assisted closure (VAC) dressing after a free muscle flap to the lower extremity. Methods Over a 19 months period, all consecutive free muscle flaps for lower extremity reconstruction at a Level I trauma center were evaluated prospectively for postoperative flap thickness, complications and flap survival. Immediate application of a VAC dressing was performed in 9 patients, while the flap was left exposed for monitoring in 8 patients. Results There was no statistically significant difference in flap survival between both cohorts. Mean flap thickness at postoperative day 5 for the VAC group was $6.4{\pm}6.4mm$, while flap thickness for the exposed flap group was $29.6{\pm}13.5mm$. Flap thickness was significantly decreased at postoperative day 5 for the VAC dressing group. Conclusions Immediate application of VAC dressing following free muscle flaps to the lower extremity does not compromise flap survival or outcomes and results in decreased flap thickness and a better aesthetic outcome.
