“…During the fluoroscopy time, operating team is far from the operating table and fracture reduction is decreased to about 1.5 min. Using of this device can also be help-ful in the intentions of computer added fracture reduction (5,6). This device helps during the reduction but also holds the achieved fragment position until definitive fixation.…”

“…Several authors tried to develop reduction devices (1)(2)(3)(4)(6)(7)(8)(9)(10) but no one pub-lished motorised nor remote controlled one. Developing and introducing such ideas in orthopaedic trauma practice will bring progress not only because of protection of the surgical team from radiation, but also, because of possibility such system to provide quicker fragment reduction using different methods of assessment of fracture reduction.…”

The objective of this study was to test clinically one new portable, motorised, remote controlled fracture reduction device. In vivo fluoroscopic analysis of the function of the device. Radiation exposure of the surgical team during fluoroscopy is one potential danger for the health. Minimal invasive surgery searching for reduction device which will hold position of the fragments during the fixation. Visual analysis was performed in 20 bone models (n=20) and fluoroscopic in vivo (n=6) closed fracture reduction using motorised, remote controlled reduction device. In vivo results showed average closed tibial and femoral fracture reduction for 96 sec. Reduction was successful in all patients. Position of the fragments was held until definitive fixation. Motorised remote controlled device is helpful in obtaining relatively quick fracture reduction with reducing of irradiation exposure of the surgical team and in holding of achieved reduction. Remote controlled, motorised reduction device reduces irradiation exposure of the surgical team, but also minimally invasive fixation methods could take advantage of easy reduction and holding of the fragment position until fixation. Motorised reduction device could be useful tool implemented in computer added reduction and robot.

“…Die Hexapodkinematik ist ein Mechanismus, der eine Bewegung in allen diesen Freiheitsgraden über die Längenverstellung von sechs linearen AHtuatoren (beim Fixateun Distraktoren) ermöglicht. Der frühere Ansatz von Viceconti [18], eine automatische Frakturreposition entlang eines berechneten Pfades mit dem Fixateur externe durchzuführen, erforderte eine individu- Jede Einheit trägt deshalb zur Gesamtstabilität bei, woraus eine hohe Belastbarkeit bei einfachem mechanischem Aufbau resultiert [6].…”

Using hexapod kinematics (Stewart platform), an external fixator was developed that can be adjusted in all six spatial degrees of freedom by means of six linear adjusting elements. With such a system, any desired three-dimensional bone movements, for example, fracture reduction or deformity correction, can be effected exactly, without having temporarily to compromise any stability already achieved or to rearrange the construction during treatment. Since the introduction of the hexapod principle by Stewart in 1965, computerized control has been deemed necessary for its application. This paper describes the mathematical basis and the software developed for clinical use. Mathematical procedures are needed for the calculation of the inverse and forward kinematics of the hexapod, and for the description of three-dimensional movements.
