TG (Tri-Goniometry) technique: Obtaining perfect angles in Z-plasty planning with a simple ruler.
The Z-plasty is used frequently in hand surgery to release post-burn scar contractures. Correct angles and equalization of each limb are the most important parts of the Z-plasty technique. ⋯ These angles are important when elongating a contracture line or decreasing tension. Our method uses only trigonometry coefficients and a simple ruler, which is easily obtained and sterilized, enabling surgeons to perform all types of Z-plasty perfectly without measuring angles using a goniometer.
