Repeated measures design for intra- and interrater reliability. ⋯ The poor reliability of the American Medical Association Guides' spinal range of motion model can result in marked variation in the percentage of whole-body impairment. These findings have implications for compensation bodies in Australia and other countries that use the American Medical Association Guides' procedure to estimate impairment in chronic low back pain patients.
-
A controlled study with a 6-month follow-up period. ⋯ The results support the hypothesis that chronic low back trouble (i.e., pain, psychological distress, and general disability) hampers the functioning of short-term memory, which results in decreased speed of information processing among patients with chronic low back trouble.

A case is reported in which late displacement of a "hangman's fracture" was managed by transoral C2-C3 fusion by using bicortical iliac crest graft and a titanium cervical locking plate. ⋯ Undisplaced fractures of the axis are not always stable. The transoral route allows good access for stabilization of displaced hangman's fractures. In special circumstances, a locking plate may prove useful in securing the bone graft. The cervical spine locking plate can be inserted transorally with no complications and by using standard instrumentation.

Case Reports
Complete rotational burst fracture of the third lumbar vertebra managed by posterior surgery. A case report.
Case report of a young man with rotational burst fracture of the third lumbar vertebra, treated by posterior surgery. ⋯ Surgery to manage lumbar burst fracture must include reduction, decompression, restoration and fusion of anterior and posterior elements by using autologous pelvic spongious autografts, and anterior or posterior instrumentation. Posterior surgery including suturing of dural sac tears, fusion of damaged structures, and transpedicular fixation is successful in young patients and patients with good bone quality.
