    ABSTRACT: To introduce a new method of flap design and to investigate the feasibility of the clinical application. Between April 2006 and November 2009, 89 patients with skin and soft tissue defects were treated. There were 47 males and 42 females with an average age of 36 years (range, 16-67 years). The injuries were caused by machine crush (38 cases), electric saw (16 cases), electricity (8 cases), traffic accident (18 cases), rolling machine (3 cases), and crash of heavy object (6 cases). The locations were forearm in 4 cases, palm in 23 cases, finger in 41 cases, lower leg in 7 cases, and dorsum of foot in 14 cases. All the cases complicated by exposure of tendons or bones. The time from injury to hospitalization was 30 minutes to 5 days (mean, 3 hours). The areas of skin and soft tissue defect ranged from 2.0 cm x 1.5 cm to 26.0 cm x 18.0 cm. The wounds were repaired with the pedicle flaps in 72 cases and the free flaps in 17 cases. All the flaps were designed with eight-point-location method. A trapezoid was made in the raw surface and the four vertexes of the trapezoid were on the edge of the raw surface. The exterior points of the heights of arciforms were made on the edge of the raw surface too. The eight points were the labelling points. The top width, the bottom width, the height of the trapezoid, and the heights of the arciforms could be measured. The above numerus were expanded 5%-10%. The expanded numerus were the corresponding numerus of the skin flap. The size of flaps ranged from 2.2 cm x 1.7 cm to 28.5 cmx 19.5 cm. The donor sites were closed directly in 17 cases, and repaired with skin grafts in 72 cases. All the flaps were successfully dissected according to flap design. When the flaps were transplanted to the wounds, tension of the flaps was appropriate. All the flaps and skin grafts survived. The wounds and incisions at donor sites healed by first intention. Eighty-nine patients were followed up 6 to 26 months (mean, 20 months). The texture, appearance, flexibility, and function of the flaps were satisfactory, and no complication occurred. The sensory restoration of the pedicle flaps were graded as S3-S4. It is an ideal and simple method to design flap using eight-point-location method. The flaps are precise in the figure and area.
