BACKGROUND Although favorable clinical outcomes have been reported for instrumented lumbar interbody fusion (LIF), adjacent segment degeneration (ASD) has been reported as a long-term complication after LIF. OBJECTIVE To investigate ASD after instrumented LIF performed at a single level and only for the homogeneous disease of adult low-grade isthmic(More)
BACKGROUND CONTEXT Lumbar degenerative kyphosis (LDK) is characterized by sagittal imbalance resulting from a loss of lumbar lordosis (LL). The pelvic incidence (PI) regulates the sagittal alignment of the spine and pelvis. PURPOSE The purpose of this study is to evaluate the spinopelvic parameters in patients with LDK and to compare them with those of a(More)
OBJECTIVE To compare radiographic analysis on the sagittal lumbar curve when standing, sitting on a chair, and sitting on the floor. METHODS Thirty asymptomatic volunteers without a history of spinal pathology were recruited. The study population comprised 11 women and 19 men with a mean age of 29.8 years. An independent observer assessed whole lumbar(More)
A 63-year-old female presented with a rare case of synovial cyst invading the dura mater and mimicking an intradural extramedullary tumor in the lumbar spine. She underwent posterior lumbar fusion with laminar wire fixation from L3 to S1 levels. She complained of severe pain along the anterolateral thigh in both legs for 1 year. Radiological examinations,(More)
OBJECTIVE Microdiscectomy (MD) is the gold standard for surgical discectomy. As a minimally invasive discectomy, automated open lumbar discectomy (AOLD) is designed to preserve annular integrity and disc height as well as effectively remove herniated disc and degenerated disc material. However, there have been no prospective clinical studies comparing their(More)
STUDY DESIGN Retrospective clinical study. OBJECTIVE To evaluate the effect of the limitation of flexion rotation clinically and radiologically after interspinous soft stabilization using a tension band system in grade 1 degenerative spondylolisthesis. SUMMARY OF BACKGROUND DATA Although several studies have been published on the clinical effects of(More)
The authors report 2 cases of nerve root herniation after discectomy of a large lumbar disc herniation caused by an unrecognized dural tear. Patients complained of the abrupt onset of radiating pain after lumbar discectomy. Magnetic resonance imaging showed cerebrospinal fluid signal in the disc space and nerve root displacement into the disc space.(More)
The occurrences of pneumothorax and pneumomediastinum are rare, but considered to be potentially life-threatening conditions in patients undergoing functional endoscopic sinus surgery under general anesthesia. Tracheobronchial rupture may results in serious complications, such as pneumothorax and pneumomediastinum. It may occur accidentally by endotracheal(More)
BACKGROUND Obese patients are at risk of complications such as slower wound healing and increased infection rates after spinal surgery. Transforaminal full-endoscopic lumbar discectomy (ELD) has advantages over conventional microdiscectomy because it decreases perioperative complications and increases favorable clinical outcomes. No clinical studies have(More)
