To our knowledge, thoracolumbar burst fractures with a neurological deficit treated with posterior decompression and interlaminar fusion have never been reported. Our study was to assess the outcome of posterior decompression and interlaminar fusion in treating thoracolumbar burst fractures with a neurological deficit. ⋯ Posterior decompression, interlaminar fusion with posterior short-segment fixation provided excellent immediate reduction for traumatic segmental kyphosis and significant spinal canal clearance, and restored vertebral body height in the fracture level in patients with a thoracolumbar burst fracture and associated neurological deficit.

We evaluated the reliability and validity of an adapted Korean version of the Roland-Morris Disability Questionnaire (RMDQ). Translation/retranslation of the English version of RMDQ was conducted, and all steps of the cross-cultural adaptation process were performed. The Korean version of the Visual Analog Scale (VAS) measure of pain, RMDQ, and the previously validated Oswestry Disability Index (ODI) were mailed to 100 consecutive patients with chronic lower back pain (LBP) of at least 3 months. ⋯ Internal consistency was found to be very good at both assessments with Cronbach's α (0.942 and 0.951 at first and second assessments, respectively). The RMDQ was correlated with the VAS (r = 0.692; P = 0.000 and r = 0.668; P = 0.000 at first and second assessments, respectively), and with the ODI (r = 0.789; P = 0.000 and r = 0.802; P = 0.000, respectively). The adapted Korean version of the RMDQ was successfully translated and showed acceptable measurement properties, and as such, is considered suitable for outcome assessments in the Korean speaking patients with LBP.

In this study, we performed anatomic and computed tomography (CT) measurements of C2 lamina in Chinese people in order to provide the anatomic and radiographic data, and to verify the clinical applicability of trans-lamina screws to this population. ⋯ The preoperative radiographic evaluation is very important to determine the suitable size of screws. The diameter of screws is mainly restricted by the thickness of C2 lamina. It is safe to use screws with a length of 2.5-3.0 cm for Chinese people. The radiographic measurement method we used is simple, accurate and reliable for preoperative measurement.
