Randomized Controlled Trial Clinical Trial
The impact of physical function and pain on work status at 1-year follow-up in patients with back pain.
A randomized, controlled trial. ⋯ Return to work was related to physical function and pain. More importance seemed to be attributed to physical performance in the intervention group than in the controls as a basis for returning patients to work.

Randomized Controlled Trial Clinical Trial
Prospective randomization of parenteral hyperalimentation for long fusions with spinal deformity: its effect on complications and recovery from postoperative malnutrition.
A prospective randomized study of total parenteral nutrition for long spinal deformity fusions as well as its effect on complications and recovery from postoperative malnutrition was performed. ⋯ The administration of postoperative total parenteral nutrition to patients with spinal deformity is safe. No statistical reduction in complications occurred in the total parenteral nutrition group despite a trend toward more rapid normalization of nutritional parameters and a decrease in postoperative nutritional depletion. The anterior/posterior-staged group with the administration of total parenteral nutrition had a lower overall complication rate and a decreased incidence of postoperative nutritional depletion than the one-stage reconstruction group. The difference in the complication rates between the two groups may relate as much to the staging as to the administration of total parenteral nutrition per se. For certain cases it may be more advisable to stage patients and deliver total parenteral nutrition than to manage the cases in a continuous (i.e., same-day) fashion.

Case Reports
Traumatic atlantoaxial rotatory dislocation with odontoid fracture: case report and review.
A case of traumatic rotatory dislocation associated with odontoid fracture is reported. ⋯ As the pivot of rotatory subluxation changed after odontoid process osteosynthesis, posterior C1-C2 arthrodesis was performed. The patient probably could have been treated in a single-stage procedure using posterior C1-C2 transarticular fixation with bicortical interspinous graft.

A reliability study was performed. ⋯ The reliability was found to be acceptable for the Astrand test and the isokinetic test at 60 degrees per second, as evaluated by the critical difference. All the tests were highly reliable according to the intraclass correlation coefficient, except for Biering-Sørensen test for healthy individuals. The critical difference is the preferable measure because calculation of the intraclass correlation coefficient may give a misleading high estimate of reliability.
