Comparative Study
A comparison of the lenke and king classification systems in the surgical treatment of idiopathic thoracic scoliosis.
Retrospective case control study. ⋯ At intermediate follow-up, there does not seem to be significant radiographic or patient reported differences whether fusion levels are in agreement, longer, or shorter than those recommended by the Lenke or King classification systems.

Prospective clinical series with comparison to retrospectively collected data. ⋯ The critical ratio correlates more closely with the presence or absence of postoperative symptoms than measures of hematoma volume, and is consistent with the clinical expectation that greater thecal sac compression may result in more severe symptoms. Few guidelines exist for postoperative lumbar MRI interpretation. The critical ratio is an important contribution.

Investigation of the effect of static compression and anisotropy on the apparent diffusivity of glucose in bovine annulus fibrosus (AF). OBJECTIVE. To determine the apparent glucose diffusivity in 2 directions (axial and radial) of bovine AF under 3 levels of compressive strain (0%, 10%, and 20%). ⋯ Diffusion of glucose in bovine AF is dependent on strain and the direction of diffusion.

Evaluation of medication ordering errors discovered on an orthopedic/spinal in-patient hospital unit and efforts initiated to reduce them. OBJECTIVE.: In this study the authors aimed to assess the frequency of medication ordering errors and to examine the impact of local measures set forth to reduce their occurrence. ⋯ Medication errors in ordering are common in orthopedics. We found in part 1 that a chart review and patient interview by the pharmacy team can detect and correct these before reaching the patient. Furthermore, we found in part 2 that the risk could be further reduced by the implementation of pharmacist-led: patient education, education of preoperative nursing personnel, improvement of forms used for data collection, and having the patients bring all of their medications on admission.
