Computer-assistierte retrograde Anbohrung der Osteochondrosis dissecans tali mittels fluoroskopischer Navigation

Abstract

Thanks to the significantly increased accuracy, fluoroscopic navigation offers a high degree of safety and efficacy for this minimally invasive procedure. The operation can easily be performed successfully causing only minimal collateral damage to the bone, preserving the joint surface. The inherent risks of the retrograde drilling of osteochondritic lesions are lower with navigation, while the radiation exposure of the patient and the staff is significantly reduced.

Navigated versus conventional drilling of the knee in a model of obesity

“…Despite emerging and spreading systems and use, only few studies exist [17][18][19][20]22,[25][26][27][28] that report clinically acceptable results in precision with a distance from the given target of below four millimeters [17][18][19]23,24,26,27]. However, the bending of a wire or the tip of a thin drill could falsify the measured distances from the target since just their length and their indirect orientation by positioning of the drilling guide are detected.…”

“…Computer-assisted orthopedic surgery (CAOS) meanwhile is well accepted in several surgical fields, for improving precision and also minimizing X-ray exposition [18][19][20][21]. Different methods like the CT-based, fluoroscopically-assisted or imageless methods are used to simultaneously generate different planes of the therapeutic object to be treated [21].…”

“…Different methods like the CT-based, fluoroscopically-assisted or imageless methods are used to simultaneously generate different planes of the therapeutic object to be treated [21]. Only few studies that describe clinically accepted results in precision exist, despite emerging and spreading systems and use [17][18][19][20][22][23][24][25]. The methods differ in these studies and different navigation systems are used that cannot directly be compared and generalized.…”

Design of a Medical Non‐Linear Drilling Device: The Influence of Twist and Wear on the Fatigue Behaviour of NiTi Wires Subjected to Bending Rotation

“…Drilling is required mainly for three purposes: to provide access to the location of intervention, to guide and position screws, implants and other medical devices, and to create channels for various therapeutic reasons [1]. These different applications of drills presently use linear drilling, i.e.…”

Sustentaculum-tali-Schraubenplatzierung bei der Versorgung von Kalkaneusfrakturen – verschiedene Navigationsverfahren im Vergleich zur konventionellen Technik

“…2). Navigiert wurde sowohl die Bohrhülse zur Bestimmung der idealen Bohrrichtung, unabhängig von einer möglichen Bohrspitzenabweichung [15] als auch die Bohrerspitze zur Bestimmung der Bohrtiefe [16]. Hierfür werden Referenzierungskugeln an den entsprechenden Instrumenten befestigt, um so deren Position mithilfe einer optoelektrischen Kamera zu bestimmen (l " Abb.…”
