How Do Pelvic Parameters Correlate With Postoperative Outcomes When the Parameters Are Not Measured Preoperatively in Patients Undergoing Instrumented Lumbar Fusion?

Objective: A normal age-adjusted sagittal alignment is an important factor in achieving long-term functional results after lumbar spinal fusion. We aim to determine if the changes in spino-pelvic alignment (SPA) correlate with post-operative functional outcomes in patients who underwent instrumented lumbar spine surgery when the parameters were not measured before.

Method: A retrospective review of medical records from 2012 to 2016, and radiographs of the patients who underwent instrumented fusion of the lumbar spine.

Spontaneous Spinal Epidural Hematoma: Correlation of Timing of Surgical Decompression and MRI Findings with Functional Neurological Outcome.

Objective: Spontaneous spinal epidural hematoma (SSEH) is a rare and morbid entity, with the prognosis affected by delayed diagnosis and surgical intervention. The correlation between the timing of the intervention and neurological recovery has not been clearly reported. We present a retrospective study of SSEH to determine the correlation between the timing of surgical intervention and changes in the spinal cord signal on magnetic resonance imaging (MRI) with the neurological outcome.

Experimental study on pressure response to graded spinal canal compromise in an burst fracture mode.

Background: Spinal cord compression is a known cause of spinal cord injury. The purpose of this study is to measure pressure response during graded spinal cord compression. This information will be important in evaluating the amount of canal compromise that can be tolerated before risking neurological injury secondary to cord compression.

Mitigating spinal cord distraction injuries: the effect of durotomy in decreasing cord interstitial pressure in vitro.

Study Design: The present study involved an in vitro examination of spinal cord interstitial pressure (CIP) during distraction before and after durotomy in three spinal cord segments obtained from five pigs.

Objectives: To determine whether durotomy can be used to decrease the elevated CIP associated with spinal cord distraction.

Summary Of Background Data: Spinal cord distraction is a known cause of spinal cord injury.

An in vitro study on the effects of freezing, spine segment, repeat measurement, and individual cord properties on cord interstitial pressure.

Study Design: In vitro study of the spinal cord tension and pressure relationships before and after thawing in 6 different spinal cord segment from 2 individual pigs.

Objectives: To determine if frozen and thawed spinal cord segments had different tension/cord interstitial pressure(CIP) relationships to fresh spinal cord segments. In addition, we will determine if the cord level, individual cord properties, and repeated CIP measurements affect the tension/CIP relationships.
