#1
David J Kohns
For patients with Marfan syndrome who present with radicular low back pain, interventional spine providers should be familiar with dural ectasia with variable diffuse thinning of the posterior wall of the lumbar spine and sacrum. Providers should carefully weigh the risks and benefits of offering elective procedures because altered anatomy may put these patients at higher risk of dural puncture. Patient selection is essential because hydrostatic pressures and/or neural tension should also be considered as potential pain generators that may not be relieved by steroid injections...

INTRODUCTION: Teeth with a palatal radicular groove are challenging to diagnose, treat, and save. We classified this condition using cone-beam computed tomographic (CBCT) cross-sectional configurations combined with radiographic and morphologic observations during an intentional replantation procedure to identify and analyze the characteristics of palatal radicular grooves comprehensively as a reference for diagnosis, treatment planning, and prognosis evaluation of this condition. METHODS: Eight cases with palatal radicular grooves present in permanent maxillary incisors were investigated by radiography and CBCT imaging before intentional replantation...

Background and Study Aims There is a paucity of literature on beginners' training and on its connection with patient safety for transforaminal epidural steroid injections (TFESIs). This study retrospectively assessed the learning curves and associated complications of neurosurgery residents never previously exposed to TFESI and compared them with experienced board-certified faculty neurosurgeons (BCFNs). Material and Methods Procedure time in minutes, dose-area product (DAP) in cGy*cm(2), periprocedural observations, and complications in 354 TFESIs for radicular pain secondary to lumbar disk herniation or lumbar spinal stenosis were extracted from operative notes and the electronic infiltration logbook in the per-injection format...

Bin Zhu, Liang Jiang, Xiao Guang Liu
The isolated epidural gas-containing pseudocyst is an uncommon pathogenic factor for severe pain of the lower limb as a result of nerve root compression. After reviewing these rare cases reported in the literature, we found that the name, pathogenesis, and treatment strategy of this pathology remained controversial. The most common treatment is conservative treatment or percutaneous aspiration which might result inpoor pain relief and high recurrence rates. Moreover, the patient who received open surgery had good clinical outcome; however, he or she might experience a significant soft tissue injury...

BACKGROUND: Spinal intradural arachnoid cysts (SIAC) are cerebrospinal fluid (CSF) filled sacs formed by arachnoid membranes and may be either idiopathic or acquired. Idiopathic cysts represent a separate entity and their aetiology remains uncertain. By far the most difficult differential diagnosis is distinguishing between idiopathic anterior spinal cord herniation (IASCH) and dorsal thoracic intradural arachnoid cysts (TIAC), due to their similarity in radiological appearance. Cine-mode (SSFP) is emerging as a novel technique in the diagnosis and operative planning of SIAC...

REVIEW
Jingjing Zhu, Xinhuan Wang, Yanjun Fang, Johannes W Von den Hoff, Liuyan Meng
Dens invaginatus is a malformation with varying anatomical features, posing challenges to treatment. Early and accurate diagnosis plays a significant role in selecting the appropriate treatment. The diagnosis of teeth with a complex root canal system including dens invaginatus has made progress with the application of three-dimensional imaging techniques in endodontics. Advanced treatment options provide hope for teeth that could not be saved before. This review discusses diagnostic methods and treatment options for teeth with dens invaginatus, and provides guidelines for the management of dens invaginatus cases in clinic...

Background Extraforaminal lumbar interbody fusion (ELIF) surgery is a muscle-sparing approach that allows the treatment of various degenerative spinal diseases. It is technical challenging to perform the ELIF approach at the L5-S1 level because the sacral ala obstructs the view of the intervertebral disk space. Methods We reported earlier on the ELIF technique in which the intervertebral disk is targeted at an angle of 45 degrees relative to the midline. In this article we describe the technical process we developed to overcome the anatomic relation between the sacral ala and the intervertebral disk space L5-S1 that hinders the ELIF approach at this level...

OBJECTIVE: To investigate whether the microscopic filamentous aggregates observed in radicular cysts are associated with the molecular identification of Actinomyces israelii. Moreover, to verify whether this bacterium can be detected in radicular cyst specimens not presenting aggregates. STUDY DESIGN: Microscopic colonies suggestive of Actinomyces were found in 8 out of 279 radicular cyst samples (case group). The case and control groups (n = 12; samples without filamentous colonies) were submitted to the semi-nested polymerase chain reaction to test the presence of A israelii...

BACKGROUND: Endodontically treated teeth are widely considered to be more susceptible to fracture than vital teeth. Obturation procedures and post placement have been a main cause of vertical root fracture. MATERIAL AND METHODS: Forty-eight human premolars with standardized weakened roots were endodontically treated and allocated to four experimental groups (n=12). After root canal treatment, in group 1, fiber posts #1 were cemented in root canals using Estelite Core Quick, and the crowns were restored with resin composite...

Phantom limb pain in amputee patients is not well defined in the literature. Also there is still no clear information on the definition and treatment of phantom radicular pain, in which amputee patients also have radicular pain. This phenomenon, called phantom radiculitis or phantom radiculopathy, has been described in a limited number of cases. If a pathological condition to cause radicular pain is present in patients with amputee, the phantom pain\'s degree is increasing. Degenerative disc diseases are the most common cause of phantom radicular pain...
