title: [Actual relevance of minimal invasive surgery in fracture treatment].
abstract: Minimal invasive osteosynthesis (MIO) should belong nowadays in the armentarium of each trauma surgeon. The tendency to minimize the invasivity of every operation is a logical development considering the goal of each surgeon to reduce the iatrogenic damage caused by the operation. The term 'MIO" stands for this criteria: Fracture zone not opened, reduction by indirect manoeuvres or percutaneously by joy-sticks, small approaches for the application of the implants, intraoperative assessment of the reduction by imaging (fluoroscopy, arthroscopy, endoscopy, etc.). Long time before the definition of "minimal invasive surgery" some technologies in trauma surgery as external fixator or intramedullary nailing already fulfilled these criteria. In the nineties of the 20th century first cases of percutaneously inserted plate osteosynthesis have been reported. This technique got a widespread acceptance under the term of MIPO (minimal invasive plate osteosynthesis) during the last five years, especially pushed with the new angular stable screw-plate systems (LISS, LCP). The main problem of the MIPO-technique is and remains the reduction (no direct manipulation possible) and their intraoperative assessment (no direct visualisation). The balance between the degree of invasivity and the achieved quality of reduction and stability is often difficult to define and must be related to several factors (localisation and type of fracture, local soft tissue conditions, quality of the bone, age and wishes of the patient, available implants, experience of the surgeon, etc.). New technologies as improved imaging, intraoperative navigation and percutaneous reduction tools will help to further reduce the invasivity of fracture surgery in the future.
