Spinal manipulation is a form of back and other musculoskeletal pain treatment that often involves a highvelocity thrust, a technique in which the joints are adjusted rapidly. The main objective of chiropractors is to correct spinal malalignment and relieve the nerves, allowing them to function optimally (Ernst In: Expert Rev Neurother 7:1451-1452 Oppenheim et al. In: Spine J 5:660-666, 2005 16-25, 2007; Thiel et al. In: Spine 32: 2375-2378. Several case reports and series have been focusing on the risks of chiropraxis, especially on the cervical spine, although the risk/benefit ratio for certain selected patients could be acceptable (Powell et al.In: Neurosurgery 33:73-78, 1993). We describe the case of a 45-year-old woman who suffered complete paraplegia shortly after a chiropractic maneuver in the thoracic spine. Dorsal CT showed a calcified disc herniation at the T8-T9 level and MRI revealed a diffuse spinal cord ischemia from T6 to the conus medullaris without spinal cord compression at the level of herniation. Despite a normal arteriography, authors suggest a vascular injury as the cause of the deficit.Keywords Chiropraxis Á Spinal cord ischemia Á Acute paraplegia Á Herniated disc
Clinical caseA 45-year-old woman was admitted to the Neurosurgery Department of our hospital with the diagnosis of traumatic thoracic disc herniation and complete paraplegia of 12 h of evolution. She was first attended to in another hospital and then urgently sent to our department.When the patient arrived at the emergency room, she had grade 0/5 motor strength in both the lower extremities, abolished deep tendon reflexes and complete sensory loss below the T8-T9 level. She had previously refused NASCIS protocol, which was offered at the first hospital, but she finally accepted it after being admitted to our department.She had a history of only diffuse, not irradiated middle and low back pain and was being treated with chiropractic sessions for 2 years. On the day of onset of her paraplegia, she went to one of those sessions and suffered an unusual but temporary thoracic pain when the chiropractor was manipulating her middle thoracic zone. Approximately 20 min after the end of the session, she felt proximal weakness in her lower extremities, and the symptoms of a complete paraplegia and spine cord shock were progressively established within a 1-2-h period.The blood and urinary analyses, including C-reactive protein levels and the globular sedimentation rate, were normal and the body temperature was 36.5°C.A magnetic resonance imaging (MRI) performed at the hospital of origin 5 h after the beginning of the weakness showed two anomalies: one disc herniation (T8-T9) (Fig. 1a) and hypersignal under the T9 level in a T2A.
