Optimal timing for decompression in post-operative epidural hematoma: a retrospective analysis and treatment flowchart.

Purpose: Post-operative epidural hematoma is a rare but devastating complication of spine surgery. The importance of timely decompression for preserving neurologic function has been repeatedly stressed, but the acceptable timescale for decompression remains controversial. The purpose of this study was to propose a diagnosis and treatment flowchart for post-operative epidural hematoma.

Indirect Spinal Decompression in Thoracolumbar Burst Fractures: Efficacy of Combined Modified Percutaneous Posterior Short-segment Fixation and Intraoperative CT Assistance.

Study Design: This is a retrospective cohort study.

Objective: To evaluate the combined modified percutaneous short-segment posterior instrumentation technique by reducing and fixating the thoracolumbar burst fracture and checking the efficacy of indirect spinal decompression using intraoperative CT. This study aims to (1) demonstrate that using modified percutaneous short-segment posterior instrumentation is enough to rebuild spinal stability and decompress the spinal stenosis for thoracolumbar burst fracture and (2) prove the effects of spinal canal decompression by intraoperative portable CT with the surgical technique.

Survival Analysis of Allografting and Antiprotrusio Cage in Treating Massive Acetabular Bone Defects.

Background: Massive acetabular bone defects reconstructed with allografting and antiprotrusio cage in revision hip arthroplasty is less reported in the literature. We here report a series of 84 antiprotrusio cages and analyze the risk factors associated with failure.

Methods: All instances of use of an antiprotrusio cage for massive acetabular defect (Paprosky type IIc, III, and pelvic discontinuity) between 2002 and 2017 in the authors' institute were reviewed after institutional review board's approval.
