Abstract
The authors propose the use of the metallic trocar used for venous catheter introduction as a pin guide and protector. These trocars are available in several internal diameters, allowing the use of 8/10 mm to 15/10 mm Kirschner pins. This technique has the following advantages: easy guiding of the pins and protection of subcutaneous neurovascular structures. The disadvantages are related to overheating and its consequences due to metal-on-metal friction.
