Comparative Study
An outcome measure for Japanese people with chronic low back pain: an introduction and validation study of Japan Low Back Pain Evaluation Questionnaire.
Development of a nationwide patient-based outcome measure for patients with chronic low back pain (CLBP). ⋯ The JLEQ was shown to be a valid and reliable questionnaire scale for measurement of patient-based outcomes in CLBP patients.

Retrospective study of consecutive patient series. ⋯ Most common causes of revision spine surgery due to sagittal imbalance were failure to enhance lumbar lordosis and adjacent disc degeneration after lumbar fusion surgery. These patients were effectively treated with a combined anterior and posterior arthrodesis. Following these surgical treatment, sagittal balance was generally improved with fair-to-good clinical outcomes, high patient satisfaction, and low perioperative complication rates.

Case Reports Comparative Study
Spinal cord injury in patients with ankylosing spondylitis: a 10-year review.
Retrospective study. ⋯ Neurologic deficits were often subtle on initial presentation, resulting in many injuries being missed because of a low index of suspicion and poor visualization of lower cervical fractures on conventional radiographs. Extension of the ankylosed kyphotic cervical spine during conventional immobilization or for radiologic procedures resulted in neurologic deficits. Patients with an ankylosed cervical spine are normally unable to see the ceiling lying supine because of cervicothoracic kyphosis and use pillows to support their head. Cervical spine alignment in a similar flexed position is essential during immobilization or imaging. Medical alert cards as for patients with diabetes would be a way forward in correctly identifying patients with AS so that appropriate precautions can be instituted by emergency services.

A retrospective clinical study. ⋯ In patients undergoing thoracolumbar surgery who are at high risk of spinal wound dehiscence, closure using a pedicled omental flap is a viable procedure that may limit the risk of dehiscence and improve outcome.

Comparative Study
Volumetric changes of iliac crest autografts used to reconstruct the anterior column in thoracolumbar fractures: a follow-up using CT scans.
Patients with a thoracolumbar injury had a reconstruction of the anterior column using an tricortical iliac crest autograft. The volume and the length of the autograft were measured after 9 and 21 months using computed tomography. ⋯ The results show that more than a third of the initial graft volume is absorbed during the consolidation process. The loss was greater, the larger the volume of the initial graft was. The efficiency, however, was not dependent on the initial graft size.
