Ankylosis Spondylosis

Cervical sagittal balance plays a pivotal role in spine surgeries as it has a significant impact on the clinical outcomes in cervical spine surgery. Image processing techniques have significantly improved the accuracy and precision of cervical surgical techniques. This study aims to investigate the effects of T1 slope (T1s) on the disappearance of cervical lordosis after posterior cervical double-door laminoplasty using medical informatics and radiographic measures. To do so, we determined and measured the loss of T1s and cervical lordosis during the postoperative follow-up period in patients with double-door posterior cervical laminoplasty...

Introduction Approximately 5-10% of strokes occur in adults of less than 45 years of age. The rising prevalence of stroke risk factors may increase stroke rates in young adults (YA). We aimed to compare risk factors and outcomes of acute ischemic stroke (AIS) among YA. Methods Adult hospitalizations for AIS and concurrent risk factors were found in the Nationwide Inpatient Sample database. Weighted analysis using chi-square and multivariable survey logistic regression was performed to evaluate AIS-related outcomes and risk factors among YA (18-45 years) and older patients...

Case summary: A rescued stray cat with an unknown history was examined for non-ambulatory paraparesis in the hindlimbs. Survey radiographs revealed typical findings of hypervitaminosis A, characterised by vertebral exostoses and extensive osteophytes, mainly in the cervicothoracic spine. CT findings were consistent with the radiographic findings, and CT-based volume rendering and virtual endoscopy into the vertebral canal were created for three-dimensional visualisation of the lesion...

A 26-year-old wheelchair-bound man was brought to our institute with progressive painful deformity of both lower limbs involving bilateral hip and knee for the past 5 years. The patient was wheelchair-bound for the past 18 months. He was only able to crawl to meet his locomotor demands. On examination, the patient was in a crouched posture with mild kyphosis at the thoracolumbar region and ankylosis of bilateral hip and knee in an unfavourable position. Radiological and serological evaluation diagnosed him to be a case of neglected ankylosing spondylosis...

OBJECTIVE: This study explored the changes of global public interest in internet search of ankylosing spondylitis (AS) based on Google Trends (GT) data, in order to reflect the characteristics of AS itself. METHODS: GT was used to obtain the search popularity scores of the term 'AS' on a global scale, between January 2004 and December 2018, under the 'health' classification. Based on the global search data of AS provided by GT, the cosinor analysis was used to test whether there was seasonality in AS...

STUDY DESIGN: Retrospective review. OBJECTIVE: Our objective was to examine the prevalence, clinical significance, ramifications, and possible etiology of postoperative bone formation at the index level after cervical disc replacement (CDR) with a minimum of 5 years of follow-up. SUMMARY OF BACKGROUND DATA: CDR can be complicated by postoperative ossification and unwanted ankylosis at the index level, which some authors have termed "heterotopic ossification...

RATIONALE: The excessive intake of vitamin A in the form of vitamin concentrate, supplement or vitamin-rich liver can result in hypervitaminosis A in man and animals. Although osteopathologies resulting from chronic vitamin A intoxication in cats are well characterized, no information is available concerning feline hypervitaminosis A-induced liver disease. CLINICAL SUMMARY: We report the first case of hepatic stellate cell lipidosis and hepatic fibrosis in a domestic cat that had been fed a diet based on raw beef liver...

INTRODUCTION: An axial symptom is one of the postoperative problems after cervical laminoplasty. The range of motion (ROM) of the cervical spine decreases after laminoplasty. It is speculated that the reduction in neck ROM is one of the causes of axial symptoms. However, most reports have focused on ROM of the cervical spine in flexion and extension, and few papers describe the rotational motion after surgery. It is impossible to assess the rotational motion in plain X-rays. This study was undertaken for the following two purposes: (1) to compare segmental rotational angles of the cervical spine between control subjects and patients with cervical laminoplasty ; (2) to analyze the relationship between postoperative axial symptoms and the range of cervical rotational angle after laminoplasty...

HISTORY AND ADMISSION FINDINGS: An 83-year-old patient with Parkinson's disease was referred because of pain in the thoracolumbar spine, increasing kyphosis and gait disturbance. Clinically, the main anomaly was a marked hyperkyphosis of the spine during standing and sitting which regressed while recumbent. INVESTIGATIONS: Radiologically, spondylosis, osteochondrosis, and facet joint arthrosis demonstrated marked degeneration of the spine (diffuse skeletal hyperostosis, DISH)...

Spondylosis deformans and diffuse idiopathic skeletal hyperostosis (DISH) are usually incidental findings and in most dogs are either asymptomatic or associated with mild clinical signs. Severe spondylosis deformans and DISH can result in complete bony fusion of consecutive vertebral segments. One of the recognised complications following vertebral fusion in human patients is the development of adjacent segment disease, which is defined as degenerative changes, most commonly degenerative intervertebral disc disease, in the mobile vertebral segment neighboring a region of complete vertebral fusion...

STUDY DESIGN: A retrospective review of 10 consecutive patients with a noninflammatory retro-odontoid pseudotumor. OBJECTIVE: To examine the radiographic characteristics in patients with a retro-odontoid pseudotumor and to evaluate the efficacy of posterior fusion. SUMMARY OF BACKGROUND DATA: A retro-odontoid pseudotumor, a reactive fibrocartilaginous mass, is known to develop after chronic atlantoaxial instability; however, one-third of the reported cases showed no overt atlantoaxial instability...

AIM: To conduct a pilot study investigating the incidence and pathology of spondylosis in a sample of cull rams in New Zealand. METHODS: Vertebral columns from 51 cull rams from different properties were assessed radiographically for evidence of spondylosis. They were graded according to severity, using a four-point grading system. Samples of intervertebral discs representing different grades of spondylosis were examined histopathologically. RESULTS: Forty (78%) rams had spondylosis in at least one intervertebral space...

In 1970 there was a conservation of Goethe's skeleton, housed in the Fürstengruft in Weimar. This procedure was kept secret until 1999. The restoration of the sarcophagus and the conservation of the skeleton have been documented together with many photos in the so-called "Sonderakte Mazeration Goethe" (special file mazeration Goethe). In this special file there are also photos of Goethe's skull and skeleton which will be published here for the first time and analysed under anthropological and palaeopathological aspects...
