Clinical Results of Percutaneous Pelvic Surgery. Computer Assisted Surgery Using Ultrasound Compared to Standard Fluoroscopy

Effectiveness of Periodontal Flap Surgery Multimedia Instructional Program Compared to Standard Lecture

Background and Aim: The aim of this study was to compare the knowledge and skill performance obtained by dental students exposed to two different instructional modalities for periodontal flap surgery: a Computer-Assisted Learning (CAL) multimedia software program and traditional lecture. Materials and Methods: In this experimental study, fifty volunteer fourth-year dental students with simil...

Robot-assisted surgery compared with open surgery and laparoscopic surgery.

Computer assisted spine surgery.

When inserting screws into a vertebral pedicle, the surgeon usually exposes the back part of the vertebra and uses his or her anatomic knowledge to align the drill in the proper direction. A slight error in direction may result in an important error in the position of the tip of the screw. This is done with no direct visibility of crucial structures (spinal cord, pleura, vessels). Statistical a...

Closed-wedge high tibial osteotomy using computer-assisted surgery compared to the conventional technique.

We assessed the reliability, accuracy and variability of closed-wedge high tibial osteotomy (HTO) using computer-assisted surgery compared to the conventional technique. A total of 50 closed-wedge HTO procedures were performed using the navigation system, and compared with 50 HTOs that had been performed with the conventional technique. In the navigation group, the mean mechanical axis prior to...

Laparoscopic Assisted ultrasound guided Percutaneous Nephrolithotomy (PCNL) in Ectopic Pelvic Kidney

We report a patient with pain, abdominal palpable mass and a history of previous open renal stone surgery.  Imaging studies showed a right pelvic kidney with multiple calyceal stones. We describe the successful management through laparoscopic assisted percutaneous nephrolithotomy with ultrasonography (PCNL) in ectopic pelvic kidney, stressing that this method is a minimally invasive therapeutic...
