Pin Malposition in External Fixator Stabilization of Combat-Related Pelvic Fractures.

The purpose of this study was to compare the accuracy of pin placement in patients with unstable pelvic fractures undergoing either iliac crest or supra-acetabular external fixation. A retrospective review was performed of computed tomography (CT) scans and injury characteristics for all patients presenting to a North Atlantic Treaty Organization Medical Treatment Facility with data entered into the Department of Defense Trauma Registry from January 2008 to October 2013 who underwent pelvic external fixation for unstable pelvic ring injuries. Thirty-two patients were analyzed.

Sagittal balance is more than just alignment: why PJK remains an unresolved problem.

Background: The durability of adult spinal deformity surgery remains problematic. Revision rates above 20 % have been reported, with a range of causes including wound infection, nonunion and adjacent level pathology. While some of these complications have been amenable to changes in patient selection or surgical technique, Proximal Junctional Kyphosis (PJK) remains an unresolved challenge.

Discrimination of human placental alkaline phosphatase allelic variants by monoclonal antibodies.

Eighteen monoclonal antibodies were produced by the mouse hybridoma method using purified placental alkaline phosphatase (ALP) as antigen. The ability of the various antibodies to discriminate among allelic variants of the enzyme was tested using a large panel of placental ALPs that had been typed electrophoretically. The panel included sets of samples of each of the six common polymorphic phenotypes as well as a series of rare variants.
