Prolong mattress use compresses the metal coil springs which may ultimately result in a compromised sleeping surface. This coil spring metal fatigue can result in spinal pain and stiffness. The purpose of this study was to compare the amount of metal fatigue of used mattress coil springs from the areas bearing greatest body weight versus areas subjected to little compression to ascertain the. Six weight bearing coil springs (WBS) were extracted from the center the used (range 8-10 yr.) mattresses (N=32) and six non-weight bearing coil springs (NWBS) were extracted from the head/foot are of the same mattresses. To determine spring weakness a special frame and platform was constructed to compare unloaded spring height with compression distance height following placement of a 1,296 g ingot on the platform. Also, a pressure gauge was used to measure the amount of pressure required to compress the coil springs a distance of 2 cm. Comparison between WBS and NWBS data were statistically treated using independent t-tests and a one-way ANOVA. There were no significant group differences in weight or height in unloaded coils. However, there were significant (p<0.05) differences in coil spring compression distance under load (WBS = 2.78 ± 0.34 cm; NWBS = 1.52 ± 0.39 cm) and force gauge compression (WBS = 1090.51 ± 88.42 g; NWBS = 1213.12 ± 71.38 g) between groups. While manufacturers’ recommendations to replace a mattress is ranges between 8 and 10 yrs., these results indicate that coil spring weakness may occur before 8 yrs. of use. Weak springs leads to loss of weight bearing capacity of the mattress thereby resulting in sagging upon use. Such sagging which may compromise sleep posture with accompanying back pain and poor sleep quality and quantity.

Herein, we aimed to compare the neurologic improvement, postoperative complications, and changes of Cobb’s angle between four main surgical approaches, including anterior cervical decompression and fusion (ACDF), laminoplasty (LAMP), laminectomy (LC), and anterior controllable antedisplacement and fusion (ACAF), to treat cervical ossification of posterior longitudinal ligament (OPLL).

Analyze the clinical profile of the spine with osteonecrosis in sickle cell disease. 610 patients were followed-up in this study between 2000 and 2017. 98 osteonecrosis were identified, 48 in the lumbar spine, 40 in the thoracic spine and 10 in both spine segments. We analyzed sex, age, genotype, and pain. Magnetic resonances and radiographs of the spine were performed.

Solitary bone plasmacytomas account for approximately 5% of plasma cell malignancies. These lesions are recognized as pre-malignant, if untreated, at least 50% will progress to multiple myeloma within 5 years of diagnosis. We present a case of a 54 year old male patient whom presented to our unit complaining of progressive axial backache complicated by acute onset paraplegia of 8 hours duration. Neurological examination revealed an incomplete L1 sensory level and no motor function of his lower limbs which had power 0/5 in all dermatomes (Frankel B).

Purpose: The purposes of this study were to examine the prevalence of psychological flag signs (yellow, black and blue) in workers who had sustained a low back injury and to examine the relationship between the presence and number of these signs and the level of pain, disability, anxiety, depression and ability to work. Methods: This study involved a review of the electronic files of injured workers with an active work-related claim related to the lumbar spine. The information on demographics, presence and number of psychosocial and workplace risk factors, level of disability as measured by the Roland Morris Disability Questionnaire (RMDQ), pain intensity as measured by the numeric pain rating scale (NPRS), and anxiety and depression as measured by the Hospital Anxiety and Depression Scale (HADS) was extracted from standardized forms.

Hydatid disease is caused by the larval form of parasitic tapeworm; Echinococcus granulosus. Primary spinal hydatid disease is rare. Primary bone localization is rare and it accounts between 0.5% and 4%. Spinal localization accounts for less than 1%. The infection may be misdiagnosed initially.

The Congenital Rubella Syndrome is a multisystemic disease and CNS involvement occurs in the form of microcephaly, mental/motor disabilities, leptomeningitis, encephalitis, vascular damage and retardation of myelination. We report a case of gross non-communicating hydrocephalus in a neonate of Congenital Rubella Syndrome which is a rare presentation.
