Background: The modified Rankin Scale (mRS) is a 6-level outcome scale used to assess level of function in neurological disease.
Objective: We examined the interobserver reliability and intraobserver reliability of the mRS-9Q, a 9 question “yes/no” survey that measures the mRS in Neurosurgical and Neurological patients.
Methods: The mRS-9Q was administered by form or telephone, and a web-based tool was used to calculate the mRS and perform error checking. Part 1 compared the mRS-9Q to a mRS Structured Interview (n=80). Part 2 compared mRS-9Q administration by telephone and by paper form (n=80). Part 3 compared mRS-9Q administration by an expert interviewer with administration by a non-expert (n=83). Part 4 examined repeatability of the mRS-9Q over a 2 week period (n=84).
Background: Lumbar discectomy is the most commonly performed spine procedure. Academic spine centers with potentially differing caseloads and experience may have different outcomes.
Objective: To determine whether the choice of center in which surgery is performed affects lumbar discectomy outcomes.
Methods: Spine Patient Outcomes Research Trial participants with a confirmed diagnosis of intervertebral disc herniation undergoing standard first-time open discectomy were followed from baseline at 6 weeks, and 3, 6, and 12 months, and yearly thereafter, at 13 spine clinics in 11 US states. Patient data from this prospective study were reviewed. Enrollment began in March 2000 and ended in November 2004.
Background: Lumbar interbody fusion has been extensively studied in the civilian population; however, data regarding its efficacy in the military are lacking.
Objective: To identify the rate of return to unrestricted active military duty after single-level lumbar interbody fusion surgery.
Methods: The surgical database at a single tertiary care military treatment facility was queried for active-duty patients who underwent a single-level lumbar interbody fusion over a 5-year period. A retrospective chart review was performed with backward stepwise logistic regression analysis, and Fisher exact and Wilcoxon rank sum tests were used for statistical analysis.
