Comparative radiation exposure using standard fluoroscopy versus cone-beam computed tomography for posterior instrumented fusion in adolescent idiopathic scoliosis.

Study Design: Retrospective cohort.

Objective: The objective of this study was to define the intraoperative radiation exposure during freehand surgical technique with fluoroscopic assistance for placement and confirmation of posterior instrumentation in patients with adolescent idiopathic scoliosis and compare data with published values using intraoperative cone-beam computed tomography (CBCT) for similar cases.

Summary Of Background Data: The treatment of idiopathic-like scoliosis used freehand placement of posterior instrumentation with fluoroscopic confirmation.

The morbidity and mortality of fusions from the thoracic spine to the pelvis in the adult population.

Study Design: A retrospective analysis.

Objective: To quantify the risks of surgery and explore the associations of early perioperative complications with patient demographics and surgical variables.

Summary Of Background Data: Long fusions extending from the thoracic spine to the pelvis in adults are increasingly common.

University of Washington orthopedic resident experience and interest in developing an international humanitarian rotation.

An academic orthopedic residency program can have a significant impact on the burden of musculoskeletal disease in low- and middle-income countries. Such an exposure may also enhance the education of a resident. A 17-question electronic survey was developed to quantify the interest of orthopedic residents in pursuing an elective international rotation.

Biomechanical comparison of lumbosacral fixation techniques in a calf spine model.

Study Design: biomechanical testing of the strength and stability of lumbosacral fixation constructs.

Objectives: The purpose of this study was to quantify and compare the biomechanical properties of five different lumbosacral fixation constructs and determine the benefit of adding supplementary fixation to S1 screws.

Summary Of Background Data: Extension of long fusions to the sacrum remains a difficult clinical challenge.
