Study Design: A retrospective cohort study.Purpose: The purpose of this study was to investigate the prevalence and risk factors for S2 alar-iliac (SAI) screw loosening following lumbosacral fixation, with a…
BACKGROUND: Good bone quality is key in avoiding a multitude of afflictions, including osteoporotic fragility fractures and poor outcomes after spine surgery. In patients undergoing instrumented spine fusion, bone quality…
Purpose: Many minimally invasive surgical (MIS) techniques have been developed for instrumentation of spine. These MIS techniques restore stability, alignment while achieving return to function quite early as compared to…
Multi-planar transverse, U-type, and vertical sacral fractures occur from high energy trauma or as pathologic fractures and often have associated neurologic and extremity injuries. Modern treatment algorithms fall into two…
In the present study, we describe autologous blood coagulum (ABC) as a physiological carrier for BMP6 to induce new bone formation. Recombinant human BMP6 (rhBMP6), dispersed within ABC and formed…
BACKGROUND: Hip and spine pathology can alter the biomechanics of spino-pelvic mobility. Lumbar spine fusions can reduce the mobility of the lumbar spine and therefore result in compensatory femoral motion,…
This is a prospective randomized study to compare the outcome of two widely used fusion methods ; posterior lumbar interbody fusion (PLIF) and posterolateral fusion (PLF) in treatment of adult…
OBJECTIVE: The objective of this cadaveric biomechanical study was to compare the area of the foraminal space during motion in the intact condition, after direct decompression via foraminotomy, and after…
