Revision of Failed Sacroiliac Joint Posterior Interpositional Structural Allograft Stabilization with Lateral Porous Titanium Implants: A Multicenter Case Series.

Background: Distraction arthrodesis (DA) and stabilization of the sacroiliac (SI) joint by placing standalone structural allograft (SA) into the joint from a posterior trajectory has recently been introduced as a surgical procedure for chronic SI joint pain refractory to non-operative care.

Methods: Retrospective case series of patients with recurrent and/or persistent pain after placement of one or more interpositional/intraarticular standalone SAs between the ilium and sacrum using a posterior procedure to treat SI joint pain/dysfunction. Patients subsequently underwent surgical revision with porous titanium fusion implants using a lateral transfixing procedure.

Cerebral hypoxia in severely brain-injured patients is associated with admission Glasgow Coma Scale score, computed tomographic severity, cerebral perfusion pressure, and survival.

Background: The purpose of this study was to determine the relationship of cerebral hypoxia with admission Glasgow Coma Scale (GCS) score, brain computed tomographic (CT) severity, cerebral perfusion pressure (CPP), and survival in patients with severe brain injury.

Methods: CPP and noninvasive transcranial oximetry (Stco2) were recorded hourly for 6 days in patients with a GCS score < or = 8 (3,722 observations). CT score was derived from midline shift (0/1) plus abnormal cisterns (0/1) plus subarachnoid hemorrhage (SAH) (0/1) (range, 0-3).

Correlation of noninvasive cerebral oximetry with cerebral perfusion in the severe head injured patient: a pilot study.

Background: Traumatic brain injury (TBI) is a leading cause of morbidity and mortality in trauma patients. Cerebral perfusion pressure (CPP) directed ICU management is recommended for patients with severe TBI. It, however, requires an invasive device to measure intracranial pressure (ICP).
