Neuromuscular stimulation via the sacral nerve roots is proposed for prevention of ischial pressure ulcers following a spinal cord injury (SCI). Acute effects of sacral functional magnetic stimulation (FMS) on seat interface pressure changes were investigated in five nondisabled volunteers. Similar effects were demonstrated with functional electrical stimulation in people with SCI who used a sa...

There is a paucity of orthopaedic literature describing avulsion of the ischial tuberosity, but its spontaneous healing does not seem to have been reported to-date. This article describes the case of a young football player who suffered an avulsion fracture of the ischial tuberosity while kicking vigorously next to the ball during a football match. The diagnosis was not made at the time of trau...

Microwave maps may provide critical information on the flux rope interaction and breakout eruption if their polarization is measured with high precision. We demonstrate this diagnostic capability using 17 GHz from Nobeyama Radioheliograph (NoRH) of a circular ribbon flare SOL2014-12-17T04:51. The EUV images SDO/AIA coronal magnetic field extrapolated HMI magnetogram are also used to support int...

PURPOSE AND METHODS Postmyelography CT studies of 84 patients with 114 thoracic herniated disks were reviewed for endplate irregularity, sclerosis, and/or disk-space calcification that could suggest a migratory path of the herniated fragment. RESULTS Abnormal straight or curvilinear densities (the "nuclear trial sign") were present at the level of the disk or endplate in 46% of the cases. MR ...

A 61-year-old man presented with orthostatic headaches and asymmetric sensorineural hearing loss (ASNHL) 8 years after cervical laminoplasty. Percussion of his cervical spine elicited Lhermitte sign. Brain MRI demonstrated trace intraventricular blood andmild superficial siderosis (figure 1); digital subtraction angiogram had normal results. CT myelogram revealed fractured hardware puncturing a...

the purpose of this historical review is to summarize the work of paul of aegina and especially his contribution to the treatment of spine disorders and trauma. a major review of the literature was undertaken with emphasis on the treatise of paul himself as well as those of later scholars and historians. paul expanded the horizons of surgery of his time, using his talent to perform very complic...

BACKGROUND Variations in position of the vermiform appendix considerably changes clinical findings. Retrocaecal appendicitis presents with slightly different clinical features from those of classical appendicitis associated with a normally sited appendix. K-sign looks for the presence of tenderness on posterior abdominal wall in the retrocaecal and paracolic appendicitis. This is the first case...

Diffuse idiopathic skeletal hyperostosis (DISH) is a noninflammatory degenerative disease that affects multiple spine levels and, in combination with osteoporosis, makes vertebrae more prone to fractures, especially in elderly people. We describe a rare case of thoracic fracture in an ankylosed spine in which hemoptysis was the only clinical sign. The patient (age in the early 80s) presented wi...
