|Spondylitis is a type of arthritis that occurs at spine. Sometimes due to increased mechanical stress, bones at spine get distorted in their shapes. For example, they get elongated or sometimes they may even get fused with each other. This results in the swelling of back or chronic back pain. This occurs in persons having more mechanical work. The pain occurring on account of this disorder can be mild or severe. The ultimate treatment for the cure of such disease is surgery in the affected area. This disorder is more common in men than women.
Review article comes in the form of systematic reviews and literature reviews and are a form of secondary literature. Systematic reviews determine an objective list of criteria, and find all previously published original research papers that meet the criteria. They then compare the results presented in these papers. Literature reviews, by contrast, provide a summary of what the authors believe are the best and most relevant prior publications.
The concept of "review article" is separate from the concept of peer-reviewed literature. It is possible for a review to be peer-reviewed, and it is possible for a review to be non-peer-reviewed.
