Intraoperative periprosthetic acetabular fracture (IPPAF) during primary total hip arthroplasty (pTHA) is a challenging complication because of lack of knowledge on typical intraoperative manifestation, poor recognition, and bad treatment outcomes. Intraoperative identification and proper management of fractures can decrease the failure rate of acetabular components. Intraoperative fracture man...

With modern technology, intraoperative computed tomography scans are being used in neurosurgical operative rooms. A case of severe head trauma is reported to underline how intraoperative computed tomography can improve the treatment of traumatic lesions, without changing the operative setup, with safety for patients and surgeons. The ability to perform an intraoperative computed tomography scan...

A recent international consensus conference on the reduction in mortality in cardiac anesthesia and intensive care included intraoperative aortic balloon pump among the ancillary (i.e. non-surgical) drugs/techniques/strategies that might influence survival rates in patients undergoing cardiac surgery. The consensus conferences state that "Pre-operative intraoperative aortic balloon pump might r...

We consider the problem of improving outcomes for neurosurgery patients by enhancing intraoperative navigation and guidance. Current navigation systems do not accurately account for intraoperative brain deformation. We focus on the brain shift deformation that occurs just after the opening of the skull and dura. The heart of our system is a nonrigid registration technique using a biomechanical ...

The aim of this study is to evaluate the relationship between patellofemoral contact stress and intraoperative knee kinematic patterns after mobile bearing total knee arthroplasty (TKA). Medial osteoarthritic knees of forty-six posterior-stabilized total knee prostheses were evaluated using a computed tomography-guided navigation system. Subjects were divided into two groups based on intraopera...

A 40-year-old woman with a 3 cm sigmoid polyp lesion who underwent a laparoscopic colon resection after intraoperative localisation of the lesion using laparoscopic ultrasonography coupled with colour power Doppler is described. She has successful intraoperative detection of the polyp followed by radical laparoscopic removal of the lesion. The advantage of using laparoscopic high resolution ult...
