Historically open reduction and internal !xation of high energy proximal tibia fractures have been associated with high rates of infection (13–88%) and nowadays staged protocol for management was proposed (1). Also articular step o"s and angular deformities after operative treatment are observed in 10–19% of cases (2). Taking all this into account the complex tibial plateau fractures management...

OBJECTIVE the objective of this study was to present an analog method for preoperative planning of primary total hip arthroplasty procedures based on measuring the components by overlaying the transparencies of the prosthesis on the preoperative radiographs and checking the accuracy, both for predicting the size of the acetabular and femoral components used and for restoring the offset and corr...

To analyse the value and accuracy of preoperative planning for total hip replacement (THR) we digitised electronically and compared the hand-sketched preoperative plans with the pre- and postoperative radiographs of 100 consecutive primary THRs. The correct type of prosthesis was planned in 98%; the agreement between planned and actually used components was 92% on the femoral side and 90% on th...

BACKGROUND Successful extraction of third molars depends on preoperative diagnosis and planning. Gold standard preoperative examinations are performed through computed tomography, decreasing risks and avoiding potential accidents. The present report highlights the value of preoperative examinations in face of accidentally displaced third molars. METHODS An 18-years-old female patient underwen...

OBJECTIVES/HYPOTHESIS Skull base surgery (SBS) involves operative tasks in close proximity to critical structures in a complex three-dimensional (3D) anatomy. The aim was to investigate the value of virtual planning (VP) based on preoperative magnetic resonance imaging (MRI) for surgical planning in SBS and to compare the effects of virtual planning with 3D contours between the expert and the s...

The surgical insertion of dental implants requires careful preoperative diagnostics. Particularly, in morphologically difficult situations a CT scan is most useful for the true to scale three-dimensional imaging of the alveolar process and the implant planning. Using a navigation system we are enabled to transfer the preoperative planning and simulation accurately into the operating situs. In t...

Background Recent advances in image-based computer assistance in the last ten years allow computerized preoperative simulations, giving a lot of advantages in the preoperative surgical planning of resections. Preoperative simulation represents the prerequisite for navigated liver surgery. The aim of this study is to describe elementary technical aspects of a navigated approach to liver resectio...
