PURPOSE: Spine surgery still remains a challenge for every spine surgeon, aware of the potential serious outcomes of misplaced instrumentation. Though many studies have highlighted that using intraoperative cone beam CT imaging and navigation systems provides higher accuracy than conventional freehand methods for placement of pedicle screws in spine surgery, few studies are concerned about how to reduce radiation exposure for patients with the use of such technology. One of the main focuses of this study is based on the ALARA principle (as low as reasonably achievable)...

Spinal cord injury (SCI) can result in paralysis of trunk muscles, which can affect sitting balance. The objective of this study was to analyze trunk muscle coordination of individuals with thoracic SCI and compare it to able-body individuals. A total of 27 individuals were recruited and subdivided into: (a) high thoracic SCI; (b) low thoracic SCI; and (c) able-body groups. Participants were seated and asked to lean their trunk in eight directions while trunk muscle activity was recorded. Muscle coordination was assessed using the non-negative matrix factorization (NMF) method to extract muscle modules, which are the synergistic trunk muscle activations, and their directional activation patterns...

PURPOSE: A multidimensional classification approach suggests that motor control impairment subgroups exist in non-specific chronic low back pain (NSCLBP). Differences in sitting lumbar posture have been identified between two such subgroups [flexion pattern (FP) and active extension pattern (AEP)] and healthy individuals; however, functional spinal movement has not been explored. This study will evaluate whether NSCLBP subgroups exhibit regional spinal kinematic differences, compared to healthy individuals, during functional tasks...

Primary non-Hodgkin's lymphoma of the vertebra is rare in the spine of the elderly. The clinical presentation and radiological features are unspecific, which make it more difficult for diagnosis. We report a case of a 79-year-old woman complaining of serious backache without any injury. The magnetic resonance imaging (MRI) showed invasion of the fifth thoracic vertebra with the posterior vertebral body wall defect. There was a high suspicion that the patient had a metastatic tumor of the vertebra. A percutaneous vertebroplasty was performed under fluoroscopic guidance, which was used to treat the osteoporotic vertebral compression fracture, vertebral metastases, verte-bral hemangioma, and multiple myeloma...

BACKGROUND: The current American Society of Regional Anesthesia (ASRA) guidelines recommend discontinuing anti-thrombotic therapy prior to any interventional spine procedures to decrease the incidence of bleeding complications. However, discontinuing anti-thrombotics may pose considerable danger in terms of cerebrovascular and cardiovascular events. Recent evidence suggests that some spinal interventions may still be performed safely with anti-thrombotics on board and some practitioners thus elect to continue certain anti-thrombotics for these procedures...

Background: Most animal studies of spinal cord injury are conducted in quadrupeds, usually rodents. It is unclear to what extent functional results from such studies can be translated to bipedal species such as humans because bipedal and quadrupedal locomotion involve very different patterns of spinal control of muscle coordination. Bipedalism requires upright trunk stability and coordinated postural muscle control; it has been suggested that peripheral sensory input is less important in humans than quadrupeds for recovery of locomotion following spinal injury...

BACKGROUND: Reporting accurate surgical complication rates to patients and their families is important in the management of adolescent idiopathic scoliosis (AIS). In this study, we report the rate of major complications following the surgical treatment of AIS both in the perioperative period and among patients with a minimum of 2 years of follow-up. METHODS: We reviewed the prospectively collected data of a multicenter registry of patients who underwent surgical treatment of AIS during the period of 1995 to 2014 in order to identify all complications...

A "dorsal spinal arachnoid web" is the thickened arachnoid band on the surface of the spinal cord which disturbs the cerebrospinal fluid (CSF) flow, known as a rare cause of thoracic myelopathy. The ideal treatment is controversial because of the risk of readhesion after simple resection of the web. A subarachnoid-subarachnoid bypass is a method to reestablish CSF flow through a silicon tube between the cranial and caudal subarachnoid space. This method is reported to be useful for traumatic syringomyelia, adhesive arachnoiditis, etc...

BACKGROUND: Conservative treatment in spine deformities and spine related disorders is mainly based on proper individual proprioceptive and motor control training. For these reasons, conservative treatment involves the stimulation of individual capability of perceiving/reducing deformities, blocks and/or improper spine posture by voluntary control. The literature describes that habitually adopted relaxed postures often exacerbate low back pain. Typically, youths can be referred to therapeutic programs aimed at improving the quality of body posture along with fostering the awareness of the importance of correct posture...

Various studies have reported alterations of spinal kinematics in patients with chronic low back pain (CLBP) during gait. However, while recent findings stressed the importance of multi-segment analysis, most of prior gait studies modelled the lumbar spine as one segment, when it was not the entire trunk that was considered as a single segment. Therefore, there is a need for comprehensive multi-segment research that could improve our understanding of CLBP pathomechanism and thus possibly contribute to better care for CLBP...

Trunk instability is a major problem for individuals with thoracic and cervical spinal cord injury. Functional electrical stimulation (FES) neuroprosthesis, a technology that uses small electrical currents to artificially contract muscles, has previously been utilized to improve trunk stability during quasistatic and dynamic sitting. The aim of this study was to develop the first powered wheelchair-based neuroprosthesis and to test its feasibility for improving trunk stability. Eleven male, able-bodied individuals participated in the feasibility study...

Speed performance during gait initiation is known to be dependent on the capacity of the central nervous system to generate efficient anticipatory postural adjustments (APA). According to the posturo-kinetic capacity (PKC) concept, any factor enhancing postural chain mobility and especially spine mobility, may facilitate the development of APA and thus speed performance. "Spinal Manipulative Therapy High-Velocity, Low-Amplitude" (SMT-HVLA) is a healing technique applied to the spine which is routinely used by healthcare practitioners to improve spine mobility...

There is limited information in the literature related to the lower back loading in patients with LBP, particularly those with non-chronic LBP. Toward addressing such a research gap, a case-control study was conducted to explore the differences in lower back mechanical loads between a group of females (n=19) with non-chronic, non-specific LBP and a group of asymptomatic females (n=19). The differences in lower back mechanical loads were determined when participants completed one symmetric lowering and lifting of a 4...

BACKGROUND: Spinal cysticercosis has been reported only in 0.7 to 3.0% of patients with neurocysticercosis. Most of the patients with spinal cysticercosis have a coexisting intracranial disease. Most often these present as intradural extramedullary lesions, involving thoracic and lumbar regions or intramedullary lesions. Intradural extramedullary primary spinal cysticercosis presenting as cervical myelopathy is extremely rare and not reported till date.

INTRODUCTION: Spinal epidural lipomatosis (SEL) is a rare condition that presents with progressive spinal cord or nerve root compression. It is commonly reported in patients receiving long-term exogenous steroid therapy or in patients with endogenous steroid overproduction. The occurrence of this condition as an idiopathic entity is rarely reported. CASE PRESENTATION: The authors present the clinical course and outcome of a 16-year-old male student, who presented with progressive spastic paraparesis of a one-year duration caused by idiopathic spinal epidural lipomatosis...

This study sought to evaluate the facilitation effect of repetitive multi-train transcranial electrical stimulation (mt-TES) at 2 repetition rates on transcranial electrical motor evoked potential (Tc-MEP) monitoring during spinal surgery, and to assess the induction rate in patients with impaired motor function from a compromised spinal cord or spinal nerve. We studied 32 consecutive patients with impaired motor function undergoing cervical or thoracic spinal surgery (470 muscles). A series of 10 TESs with 5 pulse trains were preoperatively delivered at 2 repetition rates (1 and 5 Hz)...

BACKGROUND: Active upper-limb and passive lower-limb exercise are two interventions used in the spinal cord injury (SCI) population. While the global cardiac responses have been previously studied, it is unclear how either exercise influences contractile cardiac function. Here, the cardiac contractile and volumetric responses to upper-limb (swim) and passive lower-limb exercise are investigated in rodents with a severe high-thoracic SCI. METHODS: Animals were divided into a control (CON), SCI no exercise (NO-EX), SCI passive hind-limb cycling (PHLC) or SCI swim (SWIM) group...

Thoracic disc herniation is a rare pathology for which surgical treatment is difficult. The discovery of asymptomatic or only slightly symptomatic lesions can be problematic, especially in cases of marked canal stenosis. The possibility of spontaneous resorption has been documented by a few case reports but there is no study on this subject. Our objective was to compare the clinical and radiological data for two groups of patients with significant thoracic herniation (occupying more than 20% of the spinal canal): one showing spontaneous resorption (group 1) and the other persistence of the lesion during follow up (group 2)...
