BackgroundPercutaneous pedicle screws are commonly used in minimally invasive spinal procedures. Traditional techniques of percutaneous pedicle screw placement have employed the use of multiplanar fluoroscopy and Kirschner wires (K‐wires). The use of multiplanar fluoroscopy for the placement of percutaneous pedicle screws likely increases radiation exposure to the surgeon when compared to open techniques...
BackgroundRadiation exposure to the surgeon is a concern in spinal surgery, especially with the increasing popularity of minimally invasive spinal surgery techniques. Three‐dimensional (3D) image guidance used in conjunction with cone beam computed tomography (cbCT) has a theoretical advantage of decreased radiation exposure to the surgeon and operating room (OR) staff. Radiation scatter to the environment...
BackgroundSagittal split ramus osteotomy (SSRO) can be associated with postoperative neurosensory disturbances. This study aimed to evaluate the effectiveness of computer‐assisted SSRO in reducing the incidence and severity of neurosensory alterations, using a surgical guide fabricated by computer‐aided design and rapid prototyping (to guide bone cutting lateral to the inferior alveolar nerve).
MethodsA...
BackgroundFemoral tunnel positioning is a difficult, but important factor in successful anterior cruciate ligament (ACL) reconstruction. Computer navigation can improve the anatomical planning procedure besides the tunnel placement procedure.
MethodsThe accuracy of the computer‐assisted femoral tunnel positioning method for anatomical double bundle ACL‐reconstruction with a three‐dimensional template...
Background
The aim of this study was to evaluate the accuracy of supra‐acetabular pelvic tumor resections in human, full‐body cadavers and under realistic operation room conditions with the help of a navigation system and K‐wires as guidance for the oscillating saw.
Methods
Seven hemipelvises from fresh, human, male, full‐body cadavers were used. A preoperative and a postoperative CT was performed...
Background
This study will examine the differences between human lumbar vertebrae, three‐dimensional (3D) scans of these bones, 3D models based on ‘Black‐bone’ magnetic resonance imaging (MRI) scans, and 3D‐printed models.
Materials and Methods
3D mesh models were created from the “Black‐bone” MRI data from two cadaveric human spines, and then 3D printed. Four models were analysed and compared:...
Background
Postoperative intracerebral haematomas represent a serious complication following stereotactic biopsy. We investigated the possible underlying causes – poor planning or poor execution – of postoperative intracerebral haematomas following stereotactic biopsies.
Methods
We performed a technical investigation using a retrospective single‐centre consecutive series of robot‐assisted stereotactic...
