Purpose: Un-healing and centrally located defect on back area, it is sometimes a challenge for the reconstructive surgeon. Although skin grafts are considered as the first choice for reconstruction of large skin defect on the back region, it is not always helpful but vascularized flaps provide a superior functional and aesthetic outcome. The present study was designed to investigate the clinical anatomy of the lumbar artery perforator flap to reconstruct back ulcer. Materials and Methods: Clinical anatomy study was undertaken using computed tomographic angiographic analysis. We identified the courses of lumbar arteries and its perforators, measured pedicle length by layers. The location of the perforator vessel was charted against anatomical landmarks. Results: The pedicle lengths of the third and fourth lumbar artery perforator reached a mean of 27.8 mm and 37.1 mm respectively from superficial fascia to deep fascia. The fourth perforator was more laterally located than the third perforator and less than 1 cm above the iliac crest. A case in which the fourth lumbar artery perforator was used as flap pedicle is described. Conclusion: For the reconstruction of central defect on the back area, the lumbar artery perforator flap coverage may be a good alternative option. Computed tomographic angiography can easily identify the course and location of lumbar artery perforators and can be helpful to elevate the flap successfully.

교량에서의 바닥판은 통행차량의 쾌적하고 안전한 주행성 확보하는 역할을 가진다. 동시에 교통하중의 충격 등에 의한 마모 및 전단에 저항하여 상부 구조를 보호하거나 빗물 등의 기타 기상작용이나 화학약품 등 상판의 악영향으로부터 바닥판을 보호하는 역할을 한다. 현재 일반국도상 교량은 총6,248개소로서 이를 효과적으로 관리하기 위하여 현재 차량탑재형 GPR시스템의 도입이 검토되고 있다. 본 연구에서는 교량 및 터널 현황조서 및 기타 국토해양부의 자료를 바탕으로 교량의 재령별, 상부구조형식별, 지역별, 경간장별 바닥판 상태평가등급을 분석하였다. 결과적으로 교량 바닥판 조사 우선순위 결정인자로는 바닥판 상태평가등급, 상부구조 형식, 재령, 연장이 주요 인자인 것으로 도출되었다.
