BACKGROUND: Local recurrence rates are high in sacral chordoma patients. Adjuvant radiotherapy may play a role in increasing local control. Patients with locally recurrent tumors continue to comprise a significant proportion of the sacral chordoma population and appear to have worse prognosis than those with primary tumors. High quality studies comparing presentation and treatments for primary and first local recurrent sacral chordoma tumors are sparse. PURPOSE: To determine: whether there is a difference in how primary and tumors at first recurrence present; the overall survival, local relapse free survival, and distant relapse free survival rates and prognostic factors for patients presenting with a primary tumor; overall survival, local relapse free survival, and distant relapse free survival rates and prognostic factors for patients presenting with a first local relapse; if there any differences in overall survival, local relapse free survival, and distant relapse free survival rates between patients presenting with a primary tumor and those with a first local relapse...

BACKGROUND CONTEXT: One of the common causes of low back pain is intervertebral disc degeneration. The pathophysiology of disc degeneration involves apoptosis of nucleus pulposes cells and degradation of extra cellular matrix (ECM). Caspase 3 plays a central role in apoptosis and the ADAMTS5 (A Disintegrin and Metalloproteinase with Thrombospondin motifs 5) gene plays a critical role in ECM degradation. Hence, we hypothesized that if one can silence these two genes, both apoptosis and ECM degradation can be prevented, thereby preventing the progression and even reverse disc degeneration...

BACKGROUND CONTEXT: Lumbosacral pseudoarthrosis and instrumentation failure is common with long segment constructs. Optimizing lumbosacral construct biomechanics may help to reduce failure rates. The influence of iliac screws and interbody type on range of motion (ROM), rod strain (RS), sacral screw strain (SS) is not well-established. PURPOSE: Investigate the effects of TLIF, ALIF, and iliac screws on long segment lumbosacral construct biomechanics. STUDY DESIGN: Biomechanical study PATIENT SAMPLE: Fourteen human cadaveric spine specimens OUTCOME MEASURES: Lumbosacral ROM, RS, and SS METHODS: Specimens were potted at L1 and the ilium...

#14
Gang-Un Kim, Gun Woo Lee
BACKGROUND CONTEXT: Cervical laminectomy and fusion (CLF) is a common surgical option for multilevel cord compression. Postoperative C5 palsy occurrence after CLF has been a vexing problem for spine physicians. The posterior shift of the cord following laminectomy has been implicated as a major factor for postoperative C5 palsy, but attempts by spine surgeons to mitigate excessive shift while providing sufficient decompression have not been well reported. PURPOSE: To compare the incidence of postoperative C5 palsy after performing selective blocking laminoplasty concurrently with CLF to those of conventional CLF...

BACKGROUND CONTEXT: Previous studies have shown the potential for intervertebral disc tissue regeneration is very limited. While in vivo and in vitro studies have shown that traction can restore disc height and internal pressure, in many clinical studies it was shown that axial mechanical traction for the treatment of low back pain is ineffective. PURPOSE: The aim of this study was to identify how the disc could be distracted, how to define the state of traction, and to further examine the feasibility of regenerating or restoring the degenerative disc by means of traction...

Dilip Chand Raja S, Ajoy Prasad Shetty, Balavenkat Subramanian, Rishi Mugesh Kanna, S Rajasekaran
BACKGROUND CONTEXT: Surgical procedures involving the spine are known to cause moderate to severe postoperative pain. Inadequate management of acute pain in the postoperative period results in higher morbidity, and consequently may lead to chronic pain due to central sensitization. The role of preemptive and intraoperative analgesia in management of postoperative pain has gained precedence over recent years. Pathophysiology of postoperative pain in spine surgery is unique, as it is a combination of nociceptive, inflammatory and neuronal stimuli...

Chen Xu, Hao Zhang, Wenchao Zhou, Huiqiao Wu, Xiaolong Shen, Yuanyuan Chen, Mingfang Liao, Yang Liu, Wen Yuan
BACKGROUND CONTEXT: The presence of ossification of posterior longitudinal ligament (OPLL) can lead to symptomatic spinal cord compression and myelopathy. The surgical approach in patients with myelopathy is influenced by the presence of OPLL. Diagnose of OPLL currently requires computed tomography which incurs a large dose of radiation. Circulating disease-specific microRNAs (miRNAs) may serve as promising diagnostic markers with no radiation and easy accessibility for OPLL patients...

BACKGROUND CONTEXT: Although 40% of adolescent idiopathic scoliosis (AIS) patients present with chronic back pain, the pathophysiology and underlying pain mechanisms remain poorly understood. We hypothesized that development of chronic pain syndrome in AIS is associated with alterations in pain modulatory mechanisms. PURPOSE: To identify the presence of sensitization in nociceptive pathways and to assess the efficacy of the diffuse noxious inhibitory control in patients with AIS presenting with chronic back pain...
