Different types of lumbosacral transitional vertebra (LSTV) are classified based on the relationship of the transverse process of the last lumbar vertebra to the sacrum. The Ferguson view (30° angled anteroposterior [AP] radiograph) is supposed to have a sufficient interreader reliability in classification of LSTV, but is not routinely available. Standard AP radiographs and magnetic resonance imaging (MRI) are often available, but their reliability in detection and classification of LSTV is unknown. ⋯ Standard AP radiographs are insufficient to detect or classify LSTV. Coronal MRI scans, however, are highly reliable for classification of LSTV.

Comparative Study
A perioperative cost analysis comparing single-level minimally invasive and open transforaminal lumbar interbody fusion.
Emerging literature suggests superior clinical short- and long-term outcomes of MIS (minimally invasive surgery) TLIFs (transforaminal lumbar interbody fusion) versus open fusions. Few studies to date have analyzed the cost differences between the two techniques and their relationship to acute clinical outcomes. ⋯ MIS TLIF technique demonstrated significant reductions of operative time, LOS, anesthesia time, VAS scores, and EBL compared with the open technique. This reduction in perioperative parameters translated into lower total hospital costs over a 60-day perioperative period. Although hospital reimbursements appear higher in the open group over the MIS group, shorter surgical times and LOS days in the MIS technique provide opportunities for hospitals to reduce utilization of resources and to increase surgical case volume.

Multicenter Study
Reliability and validity of the adapted Dutch version of the revised Scoliosis Research Society 22-item questionnaire.
As in other fields of medicine, there is an increasing interest among orthopedic surgeons to measure health-related quality of life in adolescent idiopathic scoliosis patients and to evaluate the burden of disease and the effectiveness of different treatment strategies. The development of the revised Scoliosis Research Society 22-item patient questionnaire (SRS-22r) enabled a comprehensive evaluation of health-related quality of life of these patients. Over the years, the SRS-22r gained wide acceptance and has been used in several different countries, languages, and cultures. The SRS-22r has not been translated into Dutch to date. ⋯ The Dutch SRS-22r had the properties needed for the measurement of patient perceived health-related quality of life of adolescent idiopathic scoliosis patients in the Netherlands. The Dutch SRS-22r could be used for the longitudinal follow-up of adolescent idiopathic scoliosis patients from adolescence to adulthood and for establishing the effects of conservative or invasive surgical treatment.

Randomized Controlled Trial
The effect of milrinone on induced hypotension in elderly patients during spinal surgery: a randomized controlled trial.
Induced hypotension is widely used intraoperatively to reduce blood loss and to improve the surgical field during spinal surgery. ⋯ We conclude that milrinone is useful for induced hypotension in elderly patients during spinal surgery.

Randomized Controlled Trial
Associations between physical therapy and long-term outcomes for individuals with lumbar spinal stenosis in the SPORT study.
A period of nonsurgical management is advocated before surgical treatment for most patients with lumbar spinal stenosis. Currently, little evidence is available to define optimal nonsurgical management. Physical therapy is often used, however its use and effectiveness relative to other nonsurgical strategies has not been adequately explored. ⋯ Many patients with lumbar spinal stenosis pursuing conservative management receive physical therapy. Using physical therapy was associated with reduced likelihood of patients receiving surgery within 1 year. Results for other outcomes were mixed with no differences in several measures. Further research is needed to examine the effectiveness of physical therapy relative to other nonsurgical management strategies for patients with lumbar spinal stenosis.
