Dynamic whole-spine MRI of contortionists

  title={Dynamic whole-spine MRI of contortionists},
  author={Spring Valley},
Many athletic activities involve extreme spinal stress, but few involve such extreme forms of spinal mobility as that of circus contortionists. In this study, five female contortionists from a Mongolian circus school, between 20 and 49 years of age, were examined using a 3T cylindrical MR imaging system (Philips Achieva) to assess pathological changes that might be associated with the contortionists’ act, in which the body is twisted into extreme positions. Additional whole-spine dynamic images…

Whole-spine dynamic magnetic resonance study of contortionists: anatomy and pathology.
Whole-spine dynamic MR imaging is a valuable tool for the evaluation of the extreme ROM in contortionists, allowing for the quantification of extreme mobility.
Posterior vertebral rim fractures.
A pictorial essay discusses the imaging findings of fracture of the posterior vertebral endplate, which resembles an acute disc prolapse with low back pain and radiculopathy, but may present with neurogenic claudication due to spinal stenosis in older patients.
Lumbar Surgery For 56 Limbus Fractures Emphasizing Noncalcified Type III Lesions
The preoperative recognition of the CA I-IV and NC III fracture types proved essential to the successful resection of five Type I, five Type II, 36 Type III, and ten Type IV fragments through extended laminotomies, hemilaminectomies, and laminectoms with the down biting curette, tamp, and mallet technique.
