Whiplash Injury

STUDY DESIGN: Review of the literature. OBJECTIVES: To present an overview of current research on whiplash injury. SUMMARY OF LITERATURE REVIEW: There are controversies over the definition, symptoms, and treatment of whiplash injury. MATERIALS AND METHODS: Review of the relevant literature. RESULTS: Symptoms of whiplash injury caused by an acceleration-deceleration force may present as widespread pain involving the neck or trapezius muscles, the interscapular area, the shoulders and arms, or as suboccipital headaches. Accompanying symptoms may include neurologic symptoms such as sensory dysfunction, motor weakness, or deep tendon reflex loss; non-specific symptoms such as dysphagia, dizziness, visual disturbances, tinnitus, deafness, memory loss, or temporo-mandibular joint disorders; and psychological symptoms such as depression, acute stress syndrome, or fear avoidance. The most important factor that facilitates spontaneous resolution of whiplash injury, which is a self-limiting disorder, has been shown to be prevention of the acute-to-chronic pain transition. Yet in spite of this knowledge the efficacy of several treatment methods for whiplash injury remains controversial. CONCLUSIONS: The appropriateness of treatment for whiplash injury should be evaluated on the basis of up to date academic research on its diagnosis and natural history.

Outcome and Complications in Surgical Treatment of Lumbar Stenosis or Spondylolisthesis in Geriatric Patients

Development of anesthesiology and improvement of surgical instruments enabled aggressive surgical treatment even in elderly patients, who require more active physical activities than they were in the past. However, there are controversies about the clinical outcome of spinal surgery in elderly patients with spinal stenosis or spondylolisthesis. The purpose of this study is to review the clinical outcome of spinal surgery in elderly patients with spinal stenosis or spondylolisthesis. MEDLINE search on English-language articles was performed. There were 39685 articles from 1967 to 2013 regarding spinal disease, among which 70 dealt with geriatric lumbar surgery. Eighteen out of 70 articles dealt with geriatric lumbar surgery under the diagnosis of spinal stenosis or spondylolisthesis. One was non-randomized prospective, and other seventeen reports were retrospective. One non-randomized prospective and twelve out of seventeen retrospective studies showed that old ages did not affect the clinical outcomes. One non-randomized prospective and ten of seventeen retrospective studies elucidated postoperative complications: some reports showed that postoperative complications increased in elderly patients, whereas the other reports showed that they did not increase. Nevertheless, most complications were minor. There were two retrospective studies regarding the mortality. Mortality which was unrelated to surgical procedure increased, but surgical procedure-related mortality did not increase. Surgery as a treatment option in the elderly patients with the spinal stenosis or spondylolisthesis may be reasonable. However, there is insufficient evidence to make strong recommendations regarding spinal surgery for geriatric patients with spinal stenosis and spondylolisthesis.
