Retrospective analysis of preoperative imaging and clinical data from patients undergoing cervical expansive laminoplasty for cervical myelopathy. ⋯ Intraoperative US was more useful than postoperative MRI for predicting the clinical outcome of cervical expansive laminoplasty. Knowledge of the predictive parameters for spinal cord floating after cervical expansive laminoplasty could help evaluate the limitations of posterior decompression.

Comparative Study
A biomechanical comparison of different types of lumbopelvic fixation.
Comparative biomechanical testing in calf spines. ⋯ With extension of instrumentation across the lumbosacral junction, our results indicate significant improvement in stability with the use of S1 screws and iliac screw fixation. Furthermore, there does not appear to be any significant difference in the location of the connector for the iliac screw.

Case series. ⋯ Ultrasound-guided L5 nerve root block using electrical nerve stimulation is a safe and effective method.
-
Retrospective functional and radiographic analysis. ⋯ When compared to a control group of equal sex, age, weight, and height, adolescent idiopathic scoliosis patients had a slightly higher incidence of back pain. When compared to the control group using short form-36 evaluation, the patients had statistically equal scores in all 8 domains. Most patients were able to perform most activities of daily living.

A retrospective study of microsurgical treatment of intramedullary spinal cord tumors (IMSCT) was conducted. ⋯ Most intramedullary spinal cord tumors need operative treatment as early as possible. The outcome of aggressive surgery now is much better than it has been in the past, and the results are acceptable. For malignant tumors and those where total removal has not been possible radiation therapy is necessary.
