The Pullout Strength of Pedicle Screws Following Redirection After Lateral Wall Breach or End-plate Breach.
STUDY DESIGN Using fresh cadavers, the biomechanical testing were used to examine the pullout strength of each pedicle screw. OBJECTIVE The aim of this study was to evaluate pullout strength of (1) a redirected pedicle screw following lateral wall breach; (2) a redirected pedicle screw following end-plate breach; and (3) a pedicle without redirection after end-plate breach without redirection...
متن کاملProtrusio After Medial Acetabular Wall Breach in Total Hip Arthroplasty.
BACKGROUND Medial protrusio is a recognized complication of total hip arthroplasty, but it is not known if a medial wall breach during cup implantation increases the risk. We thus investigated the effect of up to a 2 cm defect in the medial acetabular wall in a cadaveric model. Separately, we investigated the ability of acetabular screws to rescue the construct. METHODS Nine human fresh-froze...

متن کاملStructure free highway toll collection using non-repudiated tickets
This paper proposes a concept of how to collect toll on highways. Unlike any existing method, the proposed approach requires no structure to be built on highways for the toll collection purpose and drivers are not required to stop or even slow down to pay toll. Toll must be prepaid in advance and a driver must keep a toll ticket as proof of payment. We apply public key cryptographic operations ...
متن کاملLoculated cardiac hematoma causing hemodynamic compromise after cardiac surgery.
The authors describe a case of a rare complication occurring after cardiac surgery. Three weeks after aortic valve replacement a young male became hemodynamically unstable. The echocardiogram showed a large loculated hematoma compressing the right atrium. The patient was reoperated and the mass was removed. Recovery was complete.
