Randomized Controlled Trial
Monitoring the quality of robot-assisted pedicle screw fixation in the lumbar spine by using a cumulative summation test.
Prospective randomized controlled trial. ⋯ First, this study demonstrates the adequacy of quality control of robot-assisted pedicle screw fixation even early in the application period based on the CUSUM analysis. Second, the CUSUM test can be a useful tool for monitoring of the quality of procedures related with spine surgery.

Cross-cultural adaptation and psychometric testing. ⋯ The NDI-PT demonstrated excellent reliability and good construct validity and it may be useful for assessing functional status of Portuguese-speaking patients with CNP.

Retrospective review of medical records and administrative data. ⋯ Claims data accurately reflected certain diagnoses and type of procedures, but were less accurate at characterizing operative features other than the surgical approach. This study highlights both the potential and current limitations of claims-based analysis for spine surgery.

Retrospective study of a consecutive series of patients with thoracolumbar hyperextension injuries (TLHIs) complicated by diffuse idiopathic skeletal hyperostosis (DISH) presenting to a single institution during a 9-year period. ⋯ To our knowledge, this is the largest series of TLHIs in DISH-altered spines in literature. The study helps to understand controversial findings in literature about morphological properties of TLHIs in DISH-affected spines. Surgeons should be aware of preexisting alterations in traumatized spines and the impact on therapeutic decisions. Because of the "aging population" and implications of metabolic diseases on an "aging spine," the incidence of TLHIs in DISH will probably rise.

A cross-sectional study on baseline data. ⋯ The Dutch ODI version 2.1a is a valid and valuable tool for the measurement of functional status and disability among Dutch patients with chronic low back pain. This translated condition-specific patient-reported outcome measure version is recommended for use in future back pain research and to evaluate outcome of back care in the Netherlands.
