Chang Hong Park, Sang Ho Lee
BACKGROUND: Lumbar radicular pain often results from lumbar disc herniation, spinal stenosis, or degenerative spondylolisthesis. Minimally invasive disc decompression procedures, such as nucleo-annuloplasty or epiduroscopic neural decompression by laser, have been devised to treat such pain. OBJECTIVE: The short-term outcomes of disc decompression by endoscopic epidural laser decompression (EELD) or transforaminal epiduroscopic laser annuloplasty (TELA) were compared in patients with lumbar radicular pain due to disc herniation...

Thoracic and lumbar cortical bone trajectory pedicle screws have been described in adult spine surgery. They have likewise been described in pediatric CT-based morphometric studies; however, clinical experience in the pediatric age group is limited. The authors here describe the use of cortical bone trajectory pedicle screws in posterior instrumented spinal fusions from the upper thoracic to the lumbar spine in 12 children. This dedicated study represents the initial use of cortical screws in pediatric spine surgery...

Cerebral palsy (CP) is the most common childhood motor disability and often results in debilitating walking abnormalities, such as flexed-knee and stiff-knee gait. Current medical and surgical treatments are only partially effective in improving gait abnormalities and may cause significant muscle weakness. However, emerging artificial walking technologies, such as step-initiated, multichannel neuromuscular electrical stimulation (NMES), can substantially improve gait patterns and promote muscle strength in children with spastic CP...

PURPOSE: Body composition parameters including low muscle mass, muscle attenuation (which reflects muscle quality) and adipose tissue measurements have emerged as prognostic factors in cancer patients. However, knowledge regarding the possibility of excessive muscle loss during specific systemic therapies is unknown. We describe the changes in body composition and muscle attenuation (MA) during taxane- and anthracycline-based regimens and its association with overall survival (OS) in metastatic breast cancer patients...

PURPOSE: Even though phenotypes of disc degeneration vary on different sagittal magnetic resonance images (MRI), measurements typically are acquired on the mid-sagittal MRI. This study investigated the appropriateness of using the mid-sagittal MRI to measure various phenotypes of age-related disc degeneration. METHODS: Lumbar spine MRIs of 66 subjects (mean age 50.3 years, standard deviation 16.5 years, range 22-84 years) were studied. An image analysis program Spine Explorer was used to obtain quantitative measurements for disc height, bulging, and signal on para- and mid-sagittal T2-weighted MRIs...

The purpose of this study was to review our experience with a single case of mastoiditis associated with sigmoid sinus thrombosis and increased intracranial pressure, and to review the experience of others through prior publications. We reviewed a case of a 6-year-old boy with an acute otitis media and mastoiditis, with associated ipsilateral sigmoid sinus and contralateral distal transverse sinus thrombosis. Based on the literature and our own experience, we conclude that most children with dural sinus thrombosis from acute otitis media and mastoiditis, in the setting of increased intracranial pressure, attain a good neurological outcome with a conservative neurosurgical approach...

Isolated abdominal aortic dissection (IAAD) is a rare form of aortic dissection involving usually the infrarenal part of the abdominal aorta. A 45-year-old male presented with lumbar pain and claudication. Computed tomography angiography (CTA) revealed an infrarenal IAAD extending to the left external iliac artery (EIA), causing ≥90% narrowing of the lumen. An endovascular approach was decided, with deployment of an aortic stent-graft and two balloon expandable stents in both common iliac arteries (IAs), applying the kissing stents technique...

Y Zipori, P Jakobi, I Solt, P Abecassis
Pregnant women with lower back tattoos who wish to have an epidural placed during labour pose a dilemma to anesthesiologists. Clear guidelines have not been established. We reviewed the epidural risks in pregnant women with low back tattoos and have suggested precautionary measures to minimise them. Given the limited information available, and in the absence of a clear evidence-based medical contraindication, an epidural technique should not be excluded in those women with a lower back tattoo.

BACKGROUND: Several studies showed instantaneous axis of rotation (IAR) in the intact spine. However, there has been no report on the trajectory of the IAR of a damaged spine or that of a fixed spine with instrumentation. It is the aim of this study to investigate the trajectory of the IAR of the lumbar spine using the vertebra of deer. METHODS: Functional spinal units (L5-6) from five deer were evaluated with six-axis material testing machine. As specimen models, we prepared a normal model, a damaged model, and a pedicle screw (PS) model...

Background: HIV/HCV co-infected subjects have a significantly greater osteoporotic fracture risk than HIV-infected, despite the fact that HIV/HCV co-infection has not been associated with lower bone mineral density (BMD) than HIV or HCV alone. We evaluated if changes in bone microarchitecture , measured by trabecular bone score (TBS) could explain these differences. Design: We performed a prospective, cross-sectional cohort study of virologically suppressed HIV, untreated HCV, HIV/HCV co-infected and non-infected controls...

Interbody fusion with posterior instrumentation is a common method for treating lumbar degenerative disc diseases. However, the high rigidity of the fusion construct may produce abnormal stresses at the adjacent segment and lead to adjacent segment degeneration (ASD). As such, biodegradable implants are becoming more popular for use in orthopaedic surgery. These implants offer sufficient stability for fusion but at a reduced stiffness. Tailored to degrade over a specific timeframe, biodegradable implants could potentially mitigate the drawbacks of conventional stiff constructs and reduce the loading on adjacent segments...

RATIONALE: Lumbar burst fractures are frequent injury resulting from high-energy trauma, and the patients suffer from pain and the neurologic dysfunction. Although minimally invasive techniques have advanced rapidly, it was the first time to apply transforaminal endoscopic combined with percutaneous pedicle screw fixation to treatment of lumbar burst fractures. PATIENT CONCERNS: A 33-year-old man underwent Magerl type A3.1 burst fracture at L2 and compression fractures at L3 due to falling from a height with severe lower back pain, sensory loss, and atony of the right leg...

OBJECTIVE: Bisphosphonate (BP) drug holidays are recommended to lower the risk of rare adverse events, such as atypical femoral fractures and osteonecrosis of the jaw. However, there are minimal data on the optimal duration of these holidays. Our aim was to determine the clinical and laboratory parameters associated with increased fracture risk in patients on BP drug holiday. METHODS: A retrospective chart review was conducted of 401 patients with osteopenia or osteoporosis who began a BP drug holiday from 2004 to 2013...

X-linked hypophosphatemia (XLH) is a rare, inheritable disorder manifesting as rickets in children and osteomalacia in adults. While conventional medical treatment with oral phosphate and alfacalcidol is recommended in childhood, it is undecided whether adults should continue therapy. The aim of this 6-year prospective study was to determine the impact of conventional medical treatment on areal bone mineral density (aBMD), bone turnover markers (BTMs) and measures of calcium homeostasis in 27 adult patients with XLH, 11 of whom received medical treatment...

Iatrogenic ureteral injuries account for ∼75% of all ureteral injuries and occur primarily during urologic, gynecologic, general, and vascular surgery procedures. Ureteral injury during spine surgery is a rare complication with only occasional reports in the literature. In this case report, we present a case of unrecognized left ureteral injury during an open right lumbar discectomy with a delayed presentation, and discuss the steps required for diagnosis and management. This report highlights a rare complication during laminectomy and serves to better inform patients and surgeons about this potential complication and the management options...
