OBJECTIVE: Lumbar fusion is a procedure broadly performed for degenerative diseases of spines, but it is not without significant morbidities. Surgical Apgar Score (SAS), based on intraoperative blood loss, blood pressure, and heart rate, was developed for prognostic prediction in general and vascular operations. We aimed to examine whether the application of SAS in patients undergoing fusion procedures for degeneration of lumbar spines predicts in-hospital major complications. METHODS: One hundred and ninety-nine patients that underwent lumbar fusion operation for spine degeneration were enrolled in this retrospective study...

Clinically, vertebral fractures often occur in the upper lumbar spine and involve the superior endplate of a vertebra (which is immediately caudal to a disc). Knowledge that the cranial endplate of a disc is thicker and has greater bone mineral density (BMD) than the corresponding caudal endplate helps to explain this phenomenon. In this study, we investigated structural differences in vertebral trabeculae on either side of a lumbar disc to provide further insight into vertebral fracture risk. As the focus is trabecular difference within a spinal motion segment, we define cranial and caudal vertebral trabeculae relative to the disc...

OBJECTIVE: To investigate the biomechanical effects of the lumbar posterior complex on the adjacent segments after posterior lumbar interbody fusion (PLIF) surgeries. METHODS: A finite element model of the L1-S1 segment was modified to simulate PLIF with total laminectomy (PLIF-LAM) and PLIF with hemilaminectomy (PLIF-HEMI) procedures. The models were subjected to a 400N follower load with a 7.5-N.m moment of flexion, extension, torsion, and lateral bending. The range of motion (ROM), intradiscal pressure (IDP), and ligament force were compared...

INTRODUCTION: Endoleaks are a well-known complication after endovascular aortic repair. Type I endoleak-like phenomenon (also defined as a proximal pseudoaneurysm) post-open abdominal aortic aneurysm (AAA) repair is described as an anastomotic leak causing recurrent pressurization of the original aneurysm sac. It is rare but may result in aneurysmal sac rupture into the peritoneal cavity. REPORT: A 78-year-old man presented with a progressively enlarged aneurysmal sac due to proximal anastomotic degeneration of the proximal suture line associated with an outflow through a patent large lumbar vessel following a previous emergency open AAA repair...

OBJECTIVE: Low back pain, caused intervertebral disc degeneration has been treated by thermal annuloplasty procedure, which is a non-surgical treatement. The theoretical backgrounds of the annuloplasty are thermal destruct of nociceptor and denaturization of collagen fiber to induce contraction, to shrink annulus and thus enhancing stability. This study is about temperature and its distribution during thermal annuloplasty using 1414 nm Nd : YAG laser. METHODS: Thermal annuloplasty was performed on fresh human cadaveric lumbar spine with 20 intact intervertebral discs in a 37℃ circulating water bath using newly developed 1414 nm Nd : YAG laser...

BACKGROUND: Another rare cause of lower back pain with radiculopathy is the discal cyst. It is believed to arise from degeneration of a herniated disc, although many other theories of its origin have been proposed. Here, we report a patient with lower back pain/radiculopathy attributed originally to a herniated lumbar disc, which transformed within 6 months into a discal cyst. CASE DESCRIPTION: A 42-year-old male had a magnetic resonance (MR) documented herniated lumbar disc at the L4-5 level...

The relationship between abdominal adiposity and disc degeneration remains largely uninvestigated. Here, we investigated the association between abdominal adipose tissue thickness and lumbar disc degeneration in a cross-sectional study of 2415 participants from The Second Affiliated Hospital of Wenzhou Medical University. All subjects were scanned with a 3T Magnetic Resonance Imaging system to evaluate the degree of lumbar disc degeneration. Multiple logistic regression analysis revealed that men in the highest quartiles for abdominal diameter (AD), sagittal diameter (SAD), and ventral subcutaneous thickness (VST) were at higher odds ratio for severe lumbar disc degeneration than men in the lowest quartiles...

Autophagy has been shown to antagonize the development of Lumbar disc degeneration (LDD), whereas the molecular regulation of autophagy is unknown. We recently reported a potential role of Insulin-like growth factor 1 receptor (IGF1R)/phosphatidylinositol-3 kinase (PI3k)/Akt signaling in the initiation and progression of LDD. Here, we studied the effects of IGF1R signaling on disc cell autophagy. We showed a correction of activation of IGF1R and disc cell autophagy in the resected discs in LDD patients. In vitro, activation of IGF1R signaling antagonized the decreases in cell viability of human disc cells, HNPSV, through suppression of apoptosis and enhancement of autophagy...

BACKGROUND/OBJECTIVE: Internal disk disruption (IDD), an early event of lumbar disk degeneration, is the most common cause of low back pain. Since increased intradiskal pressure (IDP) is associated with symptoms and progression of disk degeneration, unloading a painful disk with an interspinous process device (IPD) is a rational treatment option. The goal of this study was to evaluate the effectiveness of dynamic stabilization with an IPD in the treatment of symptomatic IDD of the lumbar spine...

Sicong Wang, Lizhen Wang, Yawei Wang, Chengfei Du, Ming Zhang, Yubo Fan
In recent years, a combination of traction and vibration therapy is usually used to alleviate low back pain (LBP) in clinical settings. Combining head-down tilt (HDT) traction with vibration was demonstrated to be efficacious for LBP patients in our previous study. However, the biomechanics of the lumbar spine during this combined treatment is not well known and need quantitative analysis. In addition, LBP patients have different grades of degeneration of the lumbar spinal structure, which are often age related...
