Chirurgische Nadeln in Orthopädie und Unfallchirurgie

For surgeons in the clinic and practice, the handling of suture material is the "daily bread". Therefore, one might assume that knowledge of this material is competent and comprehensive. However, daily experience shows a different picture. Often, the knowledge regarding needle shape, needle composition as well as needle size is only marginal and the surgeon has to rely on the knowledge of his OR nurse.The choice of needle is critical for each surgical step and each tissue; however, the use of the correct suture material in relation to the tissue to be sutured is essential, not only with respect to the quality of the suture but also with respect to the traumatization of the tissue. Depending on the tissue, different requirements must be placed on or taken into account for both the needle and the sutures. The purpose of this article is to provide the most essential and basic knowledge, such as the influence of needle shape and dimensions, effect of atraumatic or traumatic (so called sharp) needles on the tissue and shape of the needle tip. The interaction between the needle holder and the needle and the surgeon's hand in different applications is presented. In this present article, the main focus is on the needle and needle holder. A follow-up article specifically dedicated to sutures is being planned. The article does not claim to be 100% complete but the most essential, everyday questions should be clarified
