Mechanics of movement for rotation flaps and a local flap template.

After studying the mechanics of rotational movement, it has become apparent that there exists a local flap template for triangulated defects. Predominant rotation and transposition movements lie at extreme ends of its spectrum. This concept offers a design improvement by which these flaps can be executed with ease and confidence in all areas of the body. Several design variations are available from the template, making the hypothesis versatile and flexible. Underlying this success is the strategic placement of the triangulated defect within an imaginary circle of skin tissue around it. The concept also provides a logical and comprehensive teaching model.
