Finger fractures present a common type of fracture of the upper limb; they are most frequently caused with a direct mechanism of injury. These fractures are mostly unstable, indicated for surgical treatment (osteosynthesis of the fracture). The principle of osteosynthesis includes appropriate reduction (realignment) of the fracture, and its stabilization with an osteosynthetic material, most commonly using screws or plates. However, reduction of dislocated fractures is very difficult, that is why a new apparatus for repositioning of bone fragments has been developed, which may be simply used to reduce the fracture and maintain its appropriate position for subsequent osteosynthesis. The multifunctional apparatus makes repositioning of fragments in patients with finger fractures more easier, improves the quality of the final result and reduces the duration of surgery. In order to improve the quality of care provided for patients with finger fractures, it is possible to recommend introduction of this newly designed device into clinical practice (shortening of the operating time and the operating cycle). Laboratory experiments performed at the VŠB – Technical University of Ostrava provide a basic overview of force characteristics of fracture fragments compression induced by screwing the apparatus together in the course of surgery. The obtained results serve as a basis for introduction of the device into everyday clinical practice.
